The Angio-Seal is a widely used arterial closure device that helps achieve faster hemostasis and provide early ambulation to patients. However, it can cause various complications in clinical practice. We present the uncommon complication of popliteal artery occlusion following Angio-Seal deployment, and describe an effective interventional approach to its treatment. Because fluoroscopy-guided Fogarty embolectomy has the advantages of complete removal of the embolus without fragmentation, and clear visualization of the exact location of the embolus during the procedure, it is a suitable method for treating this complication.

INTRODUCTIONThis paper reviews the epidemiology, aetiology and management of upper limb ischaemia in a series of 8 patients presenting to a tertiary referral centre over a 4-year period and the review of the pertinent literature.

MATERIALS AND METHODSDetails of patients admitted to Tan Tock Seng Hospital (TTSH) due to critical ischaemia of the upper limbs were obtained from admission summaries through the Computerised Patient Support System (CPSS) and operative notes through LOTUS.

RESULTSThere were 8 patients who presented with upper limb ischaemia excluding trauma and iatrogenic causes over the last 4 years. All patients underwent embolectomy. One patient had an amputation post-embolectomy. Our short-term results were encouraging with 7 patients who were well enough to be discharged. One patient had a massive brainstem stroke and was discharged home for comfort care at the request of the family.

CONCLUSIONCareful physical examination and history taking, prompt recognition of upper limb ischaemia and active approach to management in the form of embolectomy are crucial in obtaining a good outcome and reducing the risk of late disabling effects.

OBJECTIVE: To evaluate the technical feasibility and clinical outcome of percutaneous aspiration embolectomy for embolic occlusion of the superior mesenteric artery (SMA). MATERIALS AND METHODS: Between January 2010 and December 2013, 9 patients with embolic occlusion of the SMA were treated by percutaneous aspiration embolectomy in 2 academic teaching hospitals. The aspiration embolectomy procedure was performed with the 6-Fr and 7-Fr guiding catheter. Thrombolysis was performed with urokinase using a multiple-sidehole infusion catheter. The clinical outcome was investigated retrospectively. RESULTS: Superior mesenteric artery occlusion was initially diagnosed by computed tomography (CT) in all patients, and all patients had no obvious evidence of bowel infarction on CT scan. Percutaneous aspiration embolectomy was primarily performed in 6 patients, and thrombolysis was initially performed in 3 patients. In 3 patients who received primary thrombolysis, percutaneous aspiration was undertaken because the emboli were resistant to urokinase. Complete angiographic success was achieved in 6 patients and partial angiographic success was accomplished in 3 patients. One patient underwent bowel resection. One patient died of whole bowel necrosis and sepsis, and 8 patients survived without complications. CONCLUSION: Percutaneous aspiration embolectomy is a useful tool in recanalization of embolic occlusion of the SMA in select patients.
