    Repair of an abdominal aortic aneurysm in a renal transplant recipient poses many different problems due to warm ischaemia to the grafted kidney. This is a case of 50-year-old gentleman who had a pervious renal transplant with abdominal aortic aneurysm. To reduce the effects of warm ischaemia on the transplanted kidney, an axillo unifemoral bypass was done prior to aneurysm repair. This ensured continued perfusion to the transplanted kidney. The post operative period was complicated by Methicillin Resistant Staphyloccus Aureus infection of the graft.

    Abdominal aortic aneurysms (AAA) repairs are routine operations with low mortality in the developed world. There are few studies on the operative management of AAA in the Asian population.This study reports the initial results from a unit with no previous experience in this surgery by a single surgeon on completion of training.

    INTRODUCTION: There has been a paradigm shift in the treatment of AAA with the advent of endovascular aneurysm repair (EVAR). Rapid progress and evolution of endovascular technology has brought forth smaller profile devices and closure devices. Total percutaneous endovascular aneurysm repair (pEVAR) involves the usage of suture-mediated closure devices (SMCDs) at vascular access sites to avoid a traditional surgical cutdown.

    MATERIALS AND METHODS: We retrospectively reviewed our experience of pEVAR between April 2013 and July 2014. Primary success of the procedure was defined as closure of a common femoral artery (CFA) arteriotomy without the need for any secondary surgical or endovascular procedure within 30 days.

    RESULTS: In total there were 10 pEVAR cases performed in the study period, one case in Queen Elizabeth Hospital during visiting vascular service. Patients have a mean age of 73.4 year old (66-77 year old) The mean abdominal aortic size was 7.2 cm (5.6-10.0cm). Mean femoral artery diameter was 9.0 mm on the right and 8.9 mm on the left. Mean duration of surgery was 119 minutes (98- 153 minutes). 50% of patients were discharged at post-operative day one, 30%- day two and 20%- day three. Primary success was achieved in 9 patients (90%) or in 19 CFA closures (95%). No major complication was reported.

    DISCUSSION: We believe that with proper selection of patients undergoing EVAR, pEVAR offers a better option of vascular access with shorter operative time, less post- operative pain, shorter hospital stay and minimises the potential complications of a conventional femoral cutdown.

    A 68 year old man with significant cardiorespiratory risks factors presented with a ruptured thoracic aortic aneurysm (TAA). This was treated by emergency thoracic endovascular aneurysm repair (TEVAR) under general anaesthesia (GA). An incidental abdominal aortic aneurysm (AAA) was not treated. Eight months later, he presented with ruptured AAA. Due to the patient's compromised respiratory system, he underwent endovascular aneurysm repair (EVAR) under local anaesthesia (LA). He had a smoother post-operation recovery compared to the first repair under GA.

    The management of abdominal aortic aneurysms (AAA) at a private medical centre was reviewed. The criteria for surgery were AAA more than or equal to five centimeters in diameter, symptomatic AAA even if less than five centimeters and ruptured AAA. A total of 67 patients were seen between October 1991 to September 1994. The age range was 48 to 94 years, mean = 69.8. There were 58 males to nine females. Twelve patients presented with ruptured AAA. There were three suprarenal AAA and three mycotic AAA. Aneurysmectomies were performed on 50 patients. This include all patients with ruptured AAA. There was no mortality in the elective cases. One patient with ruptured AAA died, ie. an operative mortality of eight per cent. It was concluded that a very low operative mortality can be achieved in this group of high risk patients. Our results were comparable to those reported by other centres in the developed countries. Important factors contributing to these results include a team approach in a unit interested in this disease, careful pre-operative preparation and a rigid post-operative regime. For ruptured AAA, survival of the patient depended on a successful and timely operation. It was also concluded that no patient should be deemed unfit for surgery or denied an operation if they needed to have one and it was safe to transport patients with ruptured AAA to a centre where the operation can be performed.

    A 62-year-old man presented with continuous, persistent backache shortly after completion of antituberculosis medication for tuberculosis (TB) of the spine. Computed tomography scan revealed a pseudoaneurysm involving the infrarenal aorta. He was restarted on anti-TB medication and underwent repair of the pseudoaneurysm with an in situ silver-coated bifurcated Dacron graft. His postoperative recovery was uneventful and he remained well up to 12 months of follow up. To our knowledge, this is the first case in the literature where an in situ silver-impregnated vascular graft has been successfully used in treating a tuberculous pseudoaneurysm.

    A prospective collection of patients referred with a diagnosis of abdominal aortic aneurysm (AAA) to the Vascular Unit, Hospital Kuala Lumpur (HKL) between February 1993 to July 1995 were analysed. There were a total of 124 patients, with a 85 per cent (%) male preponderance. Malays formed the largest ethnic group contributing about 60%. The median age of the patients was 69 years (range 49-84). Emergency referrals and admission accounted for 46.8% of patients. Hypertension and ischaemic heart disease were the two most common co-morbid medical conditions. The number of patients who underwent surgery was only 56 (45.2%). Of this total, 34 were done electively with an operative mortality of 8.8% (3 pts). The operative mortality for emergency surgery was 59.1%. AAA is relatively common in the older age group, especially in men and it should be actively looked for, as elective surgery can be offered with acceptable morbidity and mortality.

    RATIONALE: Abdominal aortic aneurysm is an extremely rare cause of deep vein thrombosis. Here we report an elderly gentleman who presented with deep vein thrombosis and was found to have concomitant abdominal aortic aneurysm upon ultrasonographic screening. It illustrates the possibility of such an aetiology, and the importance of screening for such aneurysms in a select patient population before heparinization.

    PATIENT CONCERNS: A 73-year-old Asian gentleman with underlying hypertension, hyperlipidaemia, chronic renal failure, and history of chronic smoking presented to the emergency department with acute left lower limb swelling of 1 day. On examination, the patient was tachycardic (110 beats/minute) and hypertensive (168/84 millimeters mercury (mmHg)). The entire left lower limb was swollen with notable pitting oedema, tenderness, and warmth; left calf swelling was measured to be 4 centimeters (cm).

    DIAGNOSES: The patient's Wells score of 4 placed him in the high-risk group for deep vein thrombosis. Serum D-dimer was subsequently found to be elevated at 926 nanograms/milliliter (ng/ml). Compression ultrasonography revealed a thrombus in the left deep femoral vein, confirming the diagnosis of deep vein thrombosis. The ultrasonographic evaluation was extended to the abdominal aorta due to the patient's high risk of abdominal aortic aneurysm, and a 7-cm aneurysm was indeed found. Further computed tomography and magnetic resonance imaging localized it to the infrarenal region, with left common iliac vein compression resulting in stagnant venous return.

    INTERVENTIONS: Emergency endovascular repair was performed with insertion of an inferior vena cava filter.

    OUTCOMES: The patient was subsequently monitored in the intensive care unit and uneventfully discharged after 2 weeks.

    LESSONS: Such clinical presentations of deep vein thrombosis are rare, but physicians are reminded to consider screening for abdominal aneurysms and other anatomical causes before heparinization in patients who seemingly do not have thromboembolic risk factors. This is especially so for the high risk group of male deep vein thrombosis patients aged 65-75 years with a history of smoking who have yet to be screened for abdominal aortic aneurysms, in line with United States Preventive Services Task Force recommendations.

    A prospective study of all infrarenal abdominal aortic aneurysm (AAA) repairs both as electives and emergencies in Penang between January 1997 to December 2000 is presented. The objectives of the study were to determine the age, gender, racial distribution of the patients, the incidence, and risk factors and to summarize treatments undertaken and discuss the outcome. Among the races, the Malays were the most common presenting with infrarenal AAA. The mean age of patients operated was 68.5 years. Males were more commonly affected compared to females (12:1). Most infrarenal AAA repairs were performed as emergency operations, 33 cases (61.1%) compared to electives, 21 cases (38.9%). Total survival was 70.3% (elective 85.7%; emergency 57.6%). Mortality rate was 31.5% and the primary reason is the lack of operating time available for urgent operation and for treatment of concurrent disease states. Mycotic aneurysm with its triad of abdominal pain, fever and abdominal mass resulted in a significantly higher mortality (46.6%). Ninety six percent of the infrarenal AAA had transverse diameter greater than 6 cm. Morphologically 90.7% were fusiform AAA rather than saccular aneurysm (9.3%). Pulmonary complications (35.2%) were more common than cardiac complications (11.1%) possibly related to the urgent nature of the operation, smoking or history of pulmonary tuberculosis. Bleeding (14.8%) was the most common cause of mortality in ruptured mycotic infrarenal AAA.

    Abdominal aortic aneurysm (AAA) repairs represent a significant workload in vascular surgery in Asia. This study aimed to audit AAA surgery and evaluate the application of the Portsmouth Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM) in an Asian vascular unit for standard of care. Eighty-five consecutive surgical patients with AAA from a prospective vascular database from July 1996 to December 2001 in Sarawak were available for analysis. Comparisons between predicted deaths by P-POSSUM and observed deaths in both urgency of surgery categories (elective, urgent, emergency ruptures) and risk range groups (0-5%, >5-15%, >15-50%, >50-100%) were made. No significant difference was found between the predicted and observed rates of death for elective, urgent and emergency AAA repairs. The observed mortality rates were 5%, 18% and 30%, respectively. The observed rates of death were also comparable to P-POSSUM predicted rates of death in the various risk range groups. The POSSUM score used with the P-POSSUM mortality equation is easy to use and applicable as a comparative vascular auditing tool in Asia.
