Ear Nose Throat J, 2023 Nov;102(11):NP540-NP542.

PMID: 34219487 DOI: 10.1177/01455613211031384

SIGNIFICANCE STATEMENT: Pulsatile tinnitus with erythematous tympanic membrane mass suggests vascular pathologies such as dural arteriovenous fistula, glomus tympanicum, or aberrant carotid artery. Jugular bulb aneurysmatic diverticulum is rare but should be suspected in a case with the presence of aneurysm in other organs. An imaging study is mandatory to confirm the diagnosis. Patient must avoid digging ear as it can cause profuse bleeding. Treatment option can be open surgery or endovascular treatment.

Adi O, Fong CP, Azil A, Wahab SFA

Ultrasound J, 2019 Feb 25;11(1):1.

PMID: 31359296 DOI: 10.1186/s13089-019-0116-9

BACKGROUND: We report a case study of fat embolism seen on ultrasound at right internal jugular vein during central venous cannulation in a patient diagnosed with fat embolism syndrome. This case demonstrates the importance of ultrasound for evaluation of trauma cases with suspicion of fat embolism.

CASE PRESENTATION: A 23-year-old trauma patient with closed fracture of left femoral shaft and left humerus presented to our emergency department (ED). 11 h after admission to ED, patient became confused, hypoxic and hypotensive. He was then intubated for respiratory failure and mechanically ventilated. Transesophageal ultrasound revealed hyperdynamic heart, dilated right ventricle with no regional wall abnormalities and no major aorta injuries. Whole-body computed tomography was normal. During central venous cannulation of right internal jugular vein (IJV), we found free floating mobile hyperechoic spots, located at the anterior part of the vein. A diagnosis of fat embolism syndrome later was made based on the clinical presentation of long bone fractures and fat globulin in the blood. Despite aggressive fluid resuscitation, patient was a non-responder and needed vasopressor infusion for persistent shock. Blood aspirated during cannulation from the IJV revealed a fat globule. Patient underwent uneventful orthopedic procedures and was discharged well on day 5 of admission.

CONCLUSIONS: Point-of-care ultrasound findings of fat embolism in central vein can facilitate and increase the suspicion of fat embolism syndrome.

Fulltext Fallacy of clinical confirmatory signs in internal jugular catheterisation: a case report

Venkateswaran V

Med J Malaysia, 1986 Dec;41(4):374-6.

PMID: 3670163

Repeatedly catheterising the internal jugular vein percutaneously through the same site, between the heads of the sternomastoid, resulted in soft tissue cleavage planes. The catheter entered the pleural cavity from the superior vena cava, a site remote from the percutaneous entry.
The internal jugular line can be misplaced in spite of respiratory fluctuation, free flow, and reflux with the container lowered below cardiac level. Radiological confirmation is mandatory.

Fulltext Cavernous hemangioma mimicking anterior jugular vein phlebectesia

Irfan M, Idayu MY, Venkatesh RN

Med J Malaysia, 2010 Mar;65(1):68-9.

PMID: 21265254 MyJurnal

Cavernous hemangioma is a vascular tumor composed of large dilated blood vessels and containing large blood-filled spaces. The formation is due to dilation and thickening of the walls of the capillary loops. Most cavernous hemangiomas present at birth or soon after. On the other hand, jugular phlebectasia is an abnormal benign sacculofusiform dilatation of jugular veins. It should be considered as one of the differential diagnosis of neck swelling. Majority of the reported cases occurred in a young child. We reported a case of an elderly woman who was diagnosed clinically as anterior jugular vein phlebectesia. Histologically the mass turned out to be a cavernous hemangioma.

Fulltext Ultrasound Probe Positions for Internal Jugular Vein Cannulation: A Prospective Study of Different Techniques

Kurien M, Teo R, Zainuddin K, Azidin AM, Izaham A, Budiman M, et al.

Clin Ter, 2021 Jul 05;172(4):278-283.

PMID: 34247211 DOI: 10.7417/CT.2021.2332

Objective: We compared sonoanatomy of the internal jugular vein (IJV) the high (HA), conventional (CA) and the medial oblique approach (MA) to identify the best approach and head position for IJV cannulation.

Materials & Methods: Total of 45 volunteers aged 18-65 years were included in this study. The degree of overlap in percentage, depth of IJV from skin, antero-posterior (AP) and transverse diameters (TD) of IJV were measured in real time with ultrasound (US). Measurements were taken in the HA, CA and MA in neutral and 30° head rotation on both the right and left side of the neck.

Results: The HA had lower percentage of overlap when compared to CA and MA in neutral and 30° head rotation (p= 0.002 to ≤0.001). The IJV was more shallow in the CA and MA. The AP and TD of the IJV were larger in the MA when compared to HA (p=<0.001) and CA (p =0.026 to < 0.001) and the right IJV has a larger AP and TD in all approaches.

Discussion: The HA had the least percentage of overlap compared to CA and MA, therefore the risk of accidental ICA puncture can be reduced. The apparent overlap seen in MA may not reflect the actual scenario because of the way the US beam cuts the vessel. The AP and TD of IJV were significantly increased in the MA, which would ease CVC.

Conclusion: We conclude and recommend the medial oblique probe position with 30° head rotation provides optimal real time sonographic parameters for US guided IJV cannulation.

Fulltext Quality Assessment of Longissimus and Semitendinosus Muscles from Beef Cattle Subjected to Non-penetrative and Penetrative Percussive Stunning Methods

Sazili AQ, Norbaiyah B, Zulkifli I, Goh YM, Lotfi M, Small AH

Asian-Australas J Anim Sci, 2013 May;26(5):723-31.

PMID: 25049845 DOI: 10.5713/ajas.2012.12563

This study provides a comparative analysis of the effects of pre-slaughter penetrative and non-penetrative stunning and post-slaughter stunning on meat quality attributes in longissimus lumborum (LL) and semitendinosus (ST) muscles in heifers. Ten animals were assigned to each of four treatment groups: i) animals were subjected to conventional Halal slaughter (a clean incision through the structures at the front of the upper neck - the trachea, oesophagus, carotid arteries and jugular veins) and post-cut penetrating mechanical stun within 10 to 20 s of the neck cut (Unstunned; US); ii) high power non-penetrating mechanical stunning followed by the neck cut (HPNP); iii) low power non-penetrating mechanical stunning followed by the neck cut (LPNP); and iv) penetrative stunning using a captive bolt pistol followed by the neck cut (P). For each carcass, muscle samples were removed within 45 min of slaughter, portioned and analysed for pH, cooking loss, water holding capacity (WHC), tenderness (WBS), lipid oxidation (TBARS) and color, over a two week storage period. Stunning did not affect pH and cooking loss. Significant differences in water holding capacity, tenderness, lipid oxidation and color were present at different storage time points. HPNP stunning resulted in lower WHC and color values, particularly lightness (L*), higher TBARS values and peak force values compared with those stunned using LPNP, P and US. These adverse effects on quality were mostly encountered in the ST muscle. In conclusion, the meat quality achieved using P, LPNP and US treatments was comparable, and no treatment stood out as considerably better than another.

Internal jugular phlebectasia--an unusual cause of neck swelling

Indudharan R, Quah BS, Shuaib IL

Ann Trop Paediatr, 1999 Mar;19(1):105-8.

PMID: 10605529

We describe a 7-year-old child who presented with a soft fluctuant swelling on the neck which became more prominent during the Valsalva manoeuvre. He underwent adeno-tonsillectomy based on a mistaken diagnosis of ballooning of the pharynx secondary to enlarged adenoids and tonsils obstructing the nasopharyngeal and oropharyngeal airways. Investigations revealed the swelling to be a markedly dilated internal jugular vein. We discuss the diagnostic features and mode of treatment of this condition so as to avoid unnecessary and dangerous surgical intervention.

Fulltext Surgical and embryological perspective of a big loop of internal carotid artery extending laterally beyond internal jugular vein

Nayak SB, Shetty SD

Surg Radiol Anat, 2021 Mar;43(3):413-416.

PMID: 33231750 DOI: 10.1007/s00276-020-02619-z

Knowledge of variations of the internal carotid artery is significant to surgeons and radiologists. The internal carotid artery normally runs a straight course in the neck. Its anomalies can lead to its iatrogenic injuries. We report a case of a large loop of the internal carotid artery in a male cadaver aged about 75 years. The common carotid artery terminated by dividing it into the external carotid artery and internal carotid arteries at the level of the upper border of the thyroid cartilage. From the level of origin, the internal carotid artery coursed upwards, backwards and laterally, and formed a large loop behind the internal jugular vein. The variation was found on the left side of the neck and was unilateral. The uncommon looping of the internal carotid artery might result in altered blood flow to the brain and may lead to misperceptions in surgical, imaging, and invasive procedures.

Fulltext Stenting of vertical vein in an infant with obstructed supracardiac total anomalous pulmonary venous drainage

Lim WK, Leong MC, Samion H

Ann Pediatr Cardiol, 2016 5 24;9(2):183-5.

PMID: 27212859 DOI: 10.4103/0974-2069.173549

A 1.7 kg infant with obstructed supracardiac total anomalous pulmonary venous drainage (TAPVD) presented with severe pulmonary hypertension secondary to vertical vein obstruction. The child, in addition, had a large omphalocele that was being managed conservatively. The combination of low weight, unoperated omphalocele, and severe pulmonary hypertension made corrective cardiac surgery very high-risk. Therefore, transcatheter stenting of the stenotic vertical vein, as a bridge to corrective surgery was carried out. The procedure was carried out through the right internal jugular vein (RIJ). The stenotic segment of the vertical vein was stented using a coronary stent. After procedure, the child was discharged well to the referred hospital for weight gain and spontaneous epithelialization of the omphalocele. Stenting of the vertical vein through the internal jugular vein can be considered in very small neonates as a bridge to repair obstructed supracardiac total anomalous venous drainage.

Fulltext Hemogram responses in goats toward challenged with Corynebacterium pseudotuberculosis and its immunogen mycolic acids

Odhah MN, Abdullah FFJ, Haron AW, Lila MAM, Zamri-Saad M, Khuder Z, et al.

Vet World, 2017 Jun;10(6):655-661.

PMID: 28717318 DOI: 10.14202/vetworld.2017.655-661

AIM: This study was conducted to analyze the changes in blood profile of goats inoculated with Corynebacterium pseudotuberculosis and its immunogen mycolic acid (MA) extract.

MATERIALS AND METHODS: A total of 12 clinically healthy crossbred Boer female goats were divided into three groups; A, B and C (4 goats each per group). Group A was inoculated with 2 ml sterile phosphate buffered saline via intradermal route as the negative control group whilst Group B was inoculated with 2 ml of MA extract (1 g/ml) intradermally and Group C was then inoculated with 2 ml (1×10(9)) colony forming unit of active C. pseudotuberculosis intradermally. Blood sample was collected aseptically from the jugular vein periodically for complete blood count (CBC) analysis throughout the experimental period (3 months).

RESULT: A significant decrease (p<0.05) was observed in red blood cells, hemoglobin (Hb), packed cell volume, mean corpuscular volume and mean corpuscular Hb concentration in Groups B and C as compared to the control while WBCs, neutrophil, lymphocyte and basophil showed a significant increase (p<0.05) as compared to the control.

CONCLUSION: The inoculation of C. pseudotuberculosis and MA resulted in a significant change in the CBC, thereby, indicating that MA has a role in caseous lymphadenitis pathogenesis.

Correlation and assessment of coronary artery luminal stenosis: Post-mortem computed tomography angiogram versus histopathology

Chainchel Singh MK, Abdul Rashid SN, Abdul Hamid S, Mahmood MS, Feng SS, Mohd Nawawi H, et al.

Forensic Sci Int, 2020 Mar;308:110171.

PMID: 32032870 DOI: 10.1016/j.forsciint.2020.110171

BACKGROUND: Post-mortem Computed Tomography (PMCT) allows non-invasive or minimally invasive detection of findings that may or may not be visible during conventional autopsy, however, it does not allow the investigator to draw any conclusions regarding patency of the vessel's lumen. To address this deficiency, Post-mortem Computed Tomography Angiography (PMCTA) utilizing different contrast media and techniques have been introduced with various studies looking at the correlation between PMCTA, autopsy (gross) findings and coronary artery histology in diagnosing coronary artery disease.

OBJECTIVES: The aim of this study is to investigate the sensitivity and specificity of PMCTA in diagnosing coronary artery stenosis using water-based contrast media introduced though the vessels of the neck, compared to the gold standard of diagnosis i.e. gross and histological evaluation of the coronary artery.

METHOD: This was a cross sectional study of 158 arterial sections involving 37 subjects recruited from the National Institute of Forensic Medicine (IPFN), Hospital Kuala Lumpur (HKL). An unenhanced PMCT was performed followed by PMCTA using water-based contrast media introduced though the vessels of the neck. Coronary artery stenosis was determined using multiplanar reconstructionD while the degree of stenosis was determined by calculating the percentage of luminal diameter divided by the diameter of the vessel internal elastic.

RESULTS: The analysis of PMCTA and histopathology examinations revealed a sensitivity of 61.5%, specificity of 91.7%; positive predictive value (PPV) of 40.0% and negative predictive value (NPV) of 96.4%.

CONCLUSION: PMCTA utilizing water-based contrast introduced though the vessels of the neck yielded similar results as other methods and techniques of PMCTA. We would therefore conclude that PMCTA utilizing this technique could be used to assess the degree of calcification and the presence of significant stenosis.

Surgically important variations of the jugular veins

Nayak BS

Clin Anat, 2006 Sep;19(6):544-6.

PMID: 16372344

Knowledge of variations of veins of head and neck in relation to external jugular, anterior jugular, internal jugular, and facial veins is important to surgeons doing head and neck surgery as well as to radiologists doing catheterization and to clinicians in general. In the current case, multiple variations in the veins of the left side of neck are reported. The anterior division of retromandibular vein was absent. The facial vein continued as anterior jugular vein. The internal jugular vein was duplicated above the level of hyoid bone. There was a large communicating vein between the anterior jugular vein and anterior division of internal jugular vein. Lingual vein drained into the communicating vein. Jugular venous arch was abnormally large, doubled, and highly placed. The veins of the right side were normal.

PMID: 29379394 DOI: 10.21315/mjms2017.24.6.14

Introduction: Venous aneurysms are not as common as their arterial counterpart. The choice of management is debatable. Case Report: We present the case of a teenage boy with left external jugular vein aneurysm treated by endovascular technique. Embolisation was done using pushable microcoils with access via the femoral vein and direct puncture.

Conclusion: This form of treatment provides a less-invasive option with a more concrete evaluation of the venous abnormality and its drainage during venous aneurysm occlusion.

PMID: 30217665 DOI: 10.1016/j.forsciint.2018.08.038

We present a case of a fatal motor vehicle collision of a 22-year-old car driver, who died at the scene after losing control of his car, and subsequently collided with a tree by the roadside. The subsequent autopsy revealed penetrating injuries on the neck, severing the larynx, carotid artery, jugular vein and fracturing the cervical vertebrae. Internal examination showed the offending material to be a semi-cylindrical metal fragment, which had lodged within the paravertebral muscle. Examination of the car with the authorities found that the metal fragment originated from a defective airbag booster cannister, which shattered upon deployment.

Fulltext Cannulation of internal jugular vein in neutral head position

Lew YS, Lim SK

Med J Malaysia, 1998 Sep;53(3):227-31.

PMID: 10968158

An approach to cannulate right internal jugular vein in neutral head position is described for situations where head rotation and extension are contraindicated. Venous puncture was made immediately lateral to the carotid artery at the level of cricoid cartilage and directed caudad. In 40 patients studied, the right internal jugular vein of 97.5% of the patients were successfully located by the finder needle. The mean (SE) number of puncture attempts to locate the vein was 1.3 (0.1) per patient. In 72.5% (29 patients), the veins were located exactly at the predicted point after the first attempt. However the overall success rate for cannulation by the angiocath cannula was 87.5% and short term complication rate was 5.0%. We conclude this technique is a reliable, safe alternative for central venous access, especially in patients where cervical spine movement is contraindicated or restricted.

Internal jugular vein (IJV) aneurysm is a rare entity, and a thrombosed aneurysm poses diagnostic and management challenges. We came across a 53-year-old woman who presented with fever, vomiting and right neck swelling for a week. Laboratory investigations showed neutrophilic leucocytosis, raised acute phase reactant and blood culture yielded Klebsiella pneumoniae Ultrasound and contrast-enhanced CT neck revealed a large fusiform aneurysm of the right IJV with filling defect extending from the aneurysm into the right transverse sinus. There was a cavity at the right lower third molar tooth. MRI confirmed the findings with additional enhancing focus at right lower periodontal region. The swelling reduced after 2 weeks of medical therapy, and follow-up imaging 4 months later showed complete resolution of the aneurysm with residual thrombosis. After extensive workup, dental infection remains the only identifiable primary source leading to thrombophlebitis of the right IJV and subsequent sequelae.

PMID: 2042085

An 8-year old boy presented with a right neck swelling which appeared only intermittently. The swelling was well demonstrated by the Valsalva manoeuvre. The differential diagnosis include a laryngocele, a superior mediastinum tumour or cyst and a venous aneurysm. Plain radiography, computerized tomography, ultrasonography and venography were performed. A diagnosis of venous aneurysm was confirmed. Ultrasonography was the best modality for imaging of this rare condition. It is non-invasive and it will also delineate the extent of the lesion. The treatment is expectant. Surgery is reserved for cosmesis and symptomatic aneurysms.

High-riding jugular bulb (HRJB), although rare, may pose a challenge as it may be mistaken for other non-alarming condition, such as middle ear effusion. Patients with HRJB classically present with pulsatile tinnitus. We report a unique case of a 26-year-old patient with underlying beta thalassaemia who presented with a 2-month history of intermittent epistaxis and rhinorrhoea. Otoscopic examinations revealed a pulsatile bluish mass behind the right tympanic membrane and a dull left tympanic membrane. Imaging performed revealed a finding of dual retrotympanic pathology, which consisted of a right dehiscent HRJB and left cholesterol granuloma. We highlight a rare case of dual retrotympanic mass as well as its management.
