We present a unique case of abdominal aortic aneurysm initially presenting with inferior vena cava compression leading to deep venous thrombosis, for which the patient subsequently underwent an endovascular aortic repair. Aorto-uni-iliac endografting was performed for subacute occlusion of left common iliac artery complicated by proximal type 1 endoleak. Subsequent management of the endoleak wa...

Ultrasound can be an effective alternative to computed tomography for surveillance following endovascular aneurysm repair (EVAR). Recently, ultrasound fusion imaging with the real-time navigation system was introduced. Here we described 3 patients who underwent post-EVAR surveillance using this novel technique. Complete coregistration was achieved in all patients. The origin of left renal arter...

BACKGROUND Endovascular repair of aortic aneurysms (EVAR) is obtained through the positioning of an aortic stent-graft, which excludes the aneurysmatic dilation. Type I endoleak is the most common complication, and it is caused by an incompetent proximal or distal attachment site, causing the separation between the stent-graft and the native arterial wall, and in turn creating direct communicat...

Cone beam CT, usually used in dental area, could easily obtain 3-dimensional images using cone beam shaped ionized radiation. Cone beam CT is very useful for direct percutaneous sac injection (DPSI) which needs very precise measurement to avoid puncture of inferior vena cava or vessel around sac or stent graft. Here we describe two cases of DPSI using cone beam CT. In case 1, a 79-year-old male...

INTRODUCTION The use of a proximal Palmaz stent is a well-recognised technique to treat proximal endoleak in endovascular aortic repair. This study aimed to report the effectiveness and safety of an intra-operative Palmaz stent for immediate type 1a endoleak in Hong Kong patients. METHODS This case series was conducted at a tertiary hospital in Hong Kong. In a cohort of 494 patients who under...

OBJECTIVE We describe our initial experience with the use of the TriVascular Ovation endograft system for the treatment of abdominal aortic aneurysms (AAA). METHODS We retrospectively reviewed data from patients treated for AAA using the Ovation endograft at two institutions from January 2011 to September 2012. Main outcomes included primary success, survival, complications, and device-relate...

OBJECTIVES The objective of the present study was to evaluate short- and mid-term outcomes of the left subclavian artery (LSA) chimney stent implantation (LSACSI) during thoracic endovascular aortic repair (TEVAR), and to summarize our experience with this technique. METHODS From June 2010 to September 2012, 59 patients (49 men; mean age of 57.4 ± 13.3 years, range from 26 to 83 years) who un...

A 65-year-old male presented to the emergency department complaining of two hours of severe lower abdominal pain radiating into his left testicle. The patient described a vascular procedure in the past but did not recall the details. An emergent bedside ultrasound was performed to evaluate the abdominal aorta. During the exam an echogenic object consistent with a prior endovascular stent was di...

BACKGROUND Prior reports indicate that intentional coverage of the accessory renal arteries (ARAs) with a diameter larger than 3 mm during endovascular aneurysm repair (EVAR) increases risk of additional treatment for type II endoleak. Here, we report a case of prophylactic coil embolization for a 4 mm ARA originating from an abdominal aortic aneurysm. CASE PRESENTATION A 76-year-old woman wa...
