Popliteal artery pseudoaneurysm is uncommon. They usually result from penetrating or blunt trauma, arterial reconstructive surgery, invasive diagnostic or surgical orthopedic procedures. They can cause arterial thrombosis and limb ischeamia. We report a 53 year old Chinese gentleman with popliteal artery pseudoaneurysm who presented with right lower limb numbness and paralysis in toes extension. He gave a history of acupuncture treatment around the popliteal fossa of the affected limb. Clinical examination revealed a pulsatile mass in the popliteal fossa. Computed tomography angiography showed a large, 5 cm, pseudoaneurysm arising from the popliteal artery. A diagnostic angiogram was performed and revealed that there is no run off from the popliteal artery and the tibial vessels were reconstructed from collaterals. Endovascular intervention was carried out with an Amplatzer Vascular Plug to embolise the pseudoaneurysm. The pseudoaneurysm was successfully excluded and post-op follow up revealed no more pulsatile mass and improving lower limb function. To the best of our knowledge this is first reported case of pseudoaneurysm of the popliteal artery secondary to acupuncture in Malaysia.

A 44-year-old female was diagnosed with an ITA pseudoaneurysm in the right supraclavicular fossa. She was successfully treated with endovascular embolization. The challenges of diagnosis and treatment are discussed.

Concurrent thoracic and abdominal aortic aneurysm is uncommon. It remains a formidable surgical challenge to vascular surgeons, as decision to treat in staged or simultaneous setting still debatable. We present, here, a case of a 62-year-old-man with asymptomatic concurrent thoracic and abdominal aortic aneurysms, which was successfully treated with two-stage hybrid endovascular repair. The aim of this case report is to discuss the treatment options available, possible associated complications and measures to prevent them.

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.

Introduction: Peripheral arterial disease(PAD) and abdominal aortic aneurysm(AAA) are two important underdiagnosed vascular pathologies. As they share common risk factors with coronary arterial disease, we conducted a study to look at their prevalence among patients with acute coronary syndrome(ACS). Materials and Methods: Patients with ACS admitted to Queen Elizabeth Hospital, Malaysia, from February 2009 till August 2009 were screened prospectively for PVD and AAA. Patients’ data and clinical findings were gathered and analyzed. Measurements of ankle brachial index (ABI) and abdominal aortic diameter were performed by a single assessor. PAD was defined as ABI ≤ 0.9 or diabetic patients with signs and symptoms of PAD and absence of pedal pulses. AAA was defined as abdominal aortic diameter ≥ 3cm. Results: 102 patients were recruited with mean age of 59.5 years old. Male: female ratio was 6:1. 40.2% of patients had NSTEMI; 45.1%, STEMI and 14.7%, unstable angina. Risk factors profile is as follows: hypertension- 68.6%, smoking-56.9%, hypercholesterolemia- 52.9%, diabetes mellitus-35.3% and history of stroke- 5.9%. Median ABI was 1.1 with lowest reading of 0.4. Mean abdominal aortic size was 2.0cm with largest diameter of 3.3cm. PAD was present in 24.5% of patients and AAA in 2.0%. 68.0% of patients with PAD were asymptomatic. Smoking and age more than 60 years were independent predictors for PAD among ACS patients. Conclusions: PAD is strongly correlated with CAD with old age and smoker as independent predictors. However, association between AAA and ACS could not be established.

Middle-aortic syndrome is a surgically curable cause ofchildhood hypertension. Open surgery is traditionallyoffered but with the advance of medical technology,endovascular approached is available in many country.Failure to control BP in open surgery is as low as 4.1%compares to 13% in endovascular approaches. However,mortality is 4% in open surgery almost 2 times higher than2.3% in endovascular approach. This article presents a caseof 10 years old child treated successfully withoutcomplication with endovascular balloon dilatation, as a firstcase of such disease in East Malaysia.

INTRODUCTIONThis study aims to study how the effect of the location of patient collapses from cardiac arrest, in the residential and non-residential areas within Singapore, relates to certain survival outcomes.

MATERIALS AND METHODSA retrospective cohort study of data were done from the Cardiac Arrest and Resuscitation Epidemiology (CARE) project. Out-of- hospital cardiac arrest (OHCA) data from October 2001 to October 2004 (CARE) were used. All patients with OHCA as confirmed by the absence of a pulse, unresponsiveness and apnoea were included. All events had occurred in Singapore. Analysis was performed and expressed in terms of the odds ratio (OR) and the corresponding 95% confidence interval (CI).

RESULTSA total of 2375 cases were used for this analysis. Outcomes for OHCA in residential areas were poorer than in non-residential areas-1638 (68.9%) patients collapsed in residential areas, and 14 (0.9%) survived to discharge. This was significantly less than the 2.7% of patients who survived after collapsing in a non-residential area (OR 0.31 [0.16 - 0.62]). Multivariate logistic regression analysis showed that location alone had no independent effect on survival (adjusted OR 1.13 [0.32 - 4.05]); instead, underlying factors such as bystander CPR (OR 3.67 [1.13 - 11.97]) and initial shockable rhythms (OR 6.78 [1.95 - 23.53]) gave rise to better outcomes.

CONCLUSIONEfforts to improve survival from OHCA in residential areas should include increasing CPR by family members, and reducing ambulance response times.

The role of the dispatch centre has increasingly become a focus of attention in cardiac arrest resuscitation. The dispatch centre is part of the first link in the chain of survival because without the initiation of early access, the rest of the chain is irrelevant. The influence of dispatch can also extend to the initiation of bystander cardiopulmonary resuscitation, early defibrillation and the rapid dispatch of emergency ambulances. The new International Liaison Committee on Resuscitation, the American Heart Association and, especially, the European Resuscitation Council 2015 guidelines have been increasing their emphasis on dispatch as the key to improving out-of-hospital cardiac arrest survival.

INTRODUCTIONPrompt recognition of cardiac arrest and initiation of cardiopulmonary resuscitation (CPR) and defibrillation is necessary for good outcomes from out-of-hospital cardiac arrest (OHCA). This study aims to describe the recognition and treatment of OHCA in patients conveyed by non-emergency ambulance services (EAS) in Singapore.

MATERIALS AND METHODSThis is a multi-centre, retrospective chart review, of cases presenting to public emergency departments (EDs), conveyed by non-EAS and found to be in cardiac arrest upon ED arrival. The study was from October 2002 to August 2009. The following variables were examined: ability to recognise cardiac arrest, whether CPR was carried out by the ambulance crew and whether an automated external defibrillator (AED) was applied.

RESULTSEighty-six patients were conveyed by non-EAS and found to be in cardiac arrest upon ED arrival. Mean age was 63 years (SD 21.8), 70.9% were males. A total of 53.5% of arrests occurred in the ambulance while 70.9% were found to be asystolic upon ED arrival. Seven patients had a known terminal illness. Survival to discharge was 3.5%. Cardiac arrest went unrecognised by the ambulance crew in 38 patients (44.2%). CPR was performed in 35 patients (40.7%) of the 86 patients and AED was applied in only 10 patients (11.6%).

CONCLUSIONWe found inadequate recognition and delayed initiation of treatment for OHCA. Possible reasons include a lack of training in patient monitoring and detection of cardiac arrest, lack of CPR training, lack of confidence in performing CPR, lack of AEDs on ambulances and lack of training in their use.
