PMID: 19803294 MyJurnal

The management of epistaxis remains to be a challenging problem for most ENT surgeon especially posterior epistaxis. Most cases are managed by placement of posterior nasal packs or balloons and failure leads to more invasive techniques, involving ligation of the internal maxillary artery. The above management is associated with significant patient complication and morbidity. Endoscopic ligation or cauterization of the sphenopalatine artery has emerged as a viable and minimally invasive alternative. We have performed endoscopic cauterization of nine sphenopalatine arteries in eight patients with no further episodes of epistaxis and complications, with an average follow-up of 25 months. The mean age of the patients was 52.75 years. Fifty percent of the patients had a history of hypertension.

Fulltext Elevated plasma tissue factor levels in neonates with umbilical arterial catheter-associated thrombosis

PMID: 17694958 MyJurnal

Catheterization of the umbilical artery has been a useful aid in the management of sick neonates for the past few decades. However, it is associated with various complications. Reported studies strongly suggest a significant role of intravascular catheterization in the development of aortic thrombi. Increase in thrombosis of large vessels is believed to be related to mechanical injury in the catheterized vessels, which provide direct exposure of blood to tissue factor (TF), the primary cellular initiator of the extrinsic coagulation pathway. This study was conducted to determine the levels of plasma TF, tissue factor pathway inhibitor (TFPI) and D-dimer (DD) in infants with umbilical arterial catheter (UAC)-associated thrombosis. Quantification of TF was carried out using an in-house sandwich ELISA, whereas TFPI and DD levels were measured with commercial immunoassay kits. Infants with UAC inserted were found to have significantly higher levels of plasma TF (p < 0.001) than baseline levels. However, there were no significantly elevated levels of TFPI or DD. Infants with UAC-associated thrombosis demonstrated a greater increase of TF level (median: 414.5 pg/mL; range: -76.0, 6667.0) than infants without UAC-associated thrombosis (105.0 pg/mL; -976.0, 9480.0; p = 0.009) following UAC insertion. Our findings indicate that quantification and monitoring of TF levels could predict thrombus formation in infants with indwelling UAC. Following umbilical arterial catheterisation, infants with an approximately 3-fold rise in plasma TF levels were most at risk of developing abdominal aorta thrombosis as confirmed by real-time abdominal ultrasonography.

Anomalous arterial supply to the muscles in a combined latissimus dorsi and serratus anterior flap

Halim AS, Wan Z

Clin Anat, 2004 May;17(4):358-9.

PMID: 15108344

The combined latissimus dorsi and serratus anterior flap has been employed for large defect reconstruction and has been shown to be reliable. These flaps are based on the subscapular-thoracodorsal vascular pedicle that usually supplies both muscles. In the case reported, serratus anterior possessed an anomalous arterial supply totally independent of the subscapular pedicle. The latissimus dorsi and serratus anterior muscles were used as a combined flap to reconstruct a massive thigh defect. The combined flap required two arterial anastomoses.

Fulltext Ankle pseudoaneurysm: distal posterior tibial artery pseudoaneurysm in a child following blunt trauma

Aimanan K, Chea CH, Lim KY, Damodaran A

BMJ Case Rep, 2019 May 24;12(5).

PMID: 31129637 DOI: 10.1136/bcr-2018-228255

Pseudoaneurysm of the ankle involving the posterior tibial artery is a rare presentation with only four paediatric cases previously reported in English literature. We report a new case following blunt trauma with the clinical presentation and management strategy. A 6-year-old boy presented with a pulsatile swelling at the medial aspect of ankle following a history of blunt trauma 3 weeks ago. Imaging confirmed pseudoaneurysm involving the distal posterior tibial artery. Excision of the pseudoaneurysm was performed without any complication.

A Flowmeter Technique to Exclude Internal Mammary Artery Anastomosis Error in an Arrested Heart

Hashim SA, Amin MA, Nair A, Raja Mokhtar RA, Krishnasamy S, Cheng K

Heart Lung Circ, 2018 May;27(5):e59-e63.

PMID: 29246681 DOI: 10.1016/j.hlc.2017.11.011

The revision of an internal mammary artery graft anastomosis because of a technical error can be time-consuming and complicated and may lead to complications. Here, we describe the technical details and our early experience of using a standard transit-time flowmeter to exclude technical errors and facilitate rapid decision making for anastomosis revision in an arrested heart during aortic cross-clamping in the absence of ultrasound guidance.

Calibre persistent submucosal artery of the jejunum: a rare cause of massive gastrointestinal bleeding

Wan Muhaizan WM, Julia MJ, Al Amin D

Malays J Pathol, 2002 Dec;24(2):113-6.

PMID: 12887171

Historically a calibre persistent submucosal artery was most often described in the stomach. However in later years it was also discovered in the duodenum and jejunum. It is an uncommon and important cause of massive gastrointestinal bleeding in which failure of detection and early intervention would lead to death. In this paper we report a 27-year-old man with no significant medical history who presented at the emergency unit for recurrent melaena, haematochezia and hypotension. Initial investigations failed to localize the source of bleeding. Emergency exploratory laporatomy revealed a small jejunal mucosal nodule that was actively spurting blood. Histopathological evaluation identified a calibre persistent submucosal artery.

Internal iliac and ovarian artery ligation in the control of pelvic haemorrhage

Thavarasah AS, Sivalingam N, Almohdzar SA

Aust N Z J Obstet Gynaecol, 1989 Feb;29(1):22-5.

PMID: 2562595

Bilateral ligation of the internal iliac artery with or without ligation of the ovarian arteries was carried out in 17 patients who had life-threatening pelvic haemorrhage; 14 were due to obstetric haemorrhage, 2 followed abdominal hysterectomy and 1 intractable haemorrhage associated with carcinoma of the cervix. The procedure was successful in arresting the haemorrhage in 13 patients but 4 needed hysterectomy in spite of the ligation; 1 patient died from disseminated intravascular coagulation following surgery and 1 had cardiac arrest due to extensive blood loss during surgery and died 12 hours later. A review of the literature, a brief description of the procedure and its indications are discussed.

Effect of implantation site on outcome of tissue-engineered vascular grafts

Sologashvili T, Saat SA, Tille JC, De Valence S, Mugnai D, Giliberto JP, et al.

Eur J Pharm Biopharm, 2019 Jun;139:272-278.

PMID: 31004790 DOI: 10.1016/j.ejpb.2019.04.012

OBJECTIVE: Vascular prostheses for small caliber bypass grafts in cardiac and vascular diseases or for access surgery are still missing. Poly (Ɛ-caprolactone) (PCL) has been previously investigated by our group and showed good biocompatibility and mechanical properties in vitro and rapid endothelialisation, cellular infiltration and vascularisation in vivo yielding optimal patency in the abdominal aortic position. The aim of the present study is to evaluate our PCL graft in the carotid position and to compare its outcome to the grafts implanted in the abdominal aortic position.

METHODS: PCL grafts (1 mm ID/10 mm long) were implanted into the left common carotid artery in 20 Sprague-Dawley rats and compared to our previously published series of abdominal aortic implants. The animals were followed up to 3, 6, 12 and 24 weeks. At each time point, in vivo compliance, angiography and histological examination with morphology were performed.

RESULTS: PCL grafts showed good mechanical properties and ease of handling. The average graft compliance was 14.5 ± 1.7%/ mmHg compared to 7.8 ± 0.9% for the abdominal position and 45.1 ± 3.2%/ mmHg for the native carotid artery. The overall patency for the carotid position was 65% as compared to 100% in the abdominal position. Complete endothelialisation was achieved at 3 weeks and cell invasion was more rapid than in the aortic position. In contrast, intimal hyperplasia (IH) and vascular density were less pronounced than in the aortic position.

CONCLUSION: Our PCL grafts in the carotid position were well endothelialised with early cellular infiltration, higher compliance, lower IH and calcification compared to the similar grafts implanted in the aortic position. However, there was a higher occlusion rate compared to our abdominal aorta series. Anatomical position, compliance mismatch, flow conditions may answer the difference in patency seen.
