A 70-year-old man presented with severe pain on the right side of the abdomen for 7 days. An abdominal CT angiographic scan showed an impending rupture of a large right internal iliac artery aneurysm which compressed to a right ureter causing hydroureteronephrosis. Fornix rupture of a right duplex kidney was also detected. Selective embolization of right gluteal arteries and then ligation of th...

Aberrant right subclavian artery aneurysms are rare but demonstrate a propensity toward rupture; thus, early elective repair is mandated. Novel endovascular modalities are available to offer less-invasive treatment for a patient population with increasing comorbidities. We report a case of a 65-year-old woman with an aberrant right subclavian artery aneurysm causing dysphagia lusoria. The aneur...

Background Cerebral artery vasospasm accounts for the majority of delayed neurological deficits in ruptured aneurysm patients. We report two cases and review the literature* of patients who developed symptomatic vasospasm after treatment for unruptured cerebral artery aneurysms with clip ligation. Preand post-operative imaging and studies revealed absence of subarachnoid or focal hemorrhage. Ca...

A case of aneurysm of the extra-cranial section of the internal carotid artery extending to the base of the skull is described. Treatment comprised proximal vessel ligation, the tolerance of the patient's cerebral circulation to this procedure first being assessed by measuring the back pressure across the circle of Willis after temporary carotid artery occlusion. The value of this technique is ...

A 32 year old female with hyperprolactinaemia-galactorrhoea-amenorrhoea due to a right internal carotid artery aneurysm just before its bifurcation is described. She had two episodes of subarachnoid haemorrhage necessitating an emergency internal carotid artery ligation. She responded to bromocriptine treatment with restoration of her menses, normalization of circulating prolactin and disappear...

OBJECTIVE To determine the long-term outcome of surgical repair of popliteal artery aneurysms (PAA). METHODS A retrospective review of consecutive patients who underwent surgical PAA repair in two vascular surgery units between 1988 and 2006 was performed. Primary and secondary graft patency, limb salvage and patient survival rates were determined using Kaplan-Meier methods. RESULTS 48 pati...

Background If only proximal embolization or ligation is performed for an internal iliac artery aneurysm (IIAA), transcatheter arterial embolization is sometimes difficult due to complex collateral circulation. A new method of direct percutaneous n-butyl-2-cyanoacrylate (NBCA) sac embolization (b-DNSE) under balloon arterial occlusion for re-intervention of an IIAA after proximal ligation is pre...

Carotid occlusions are associated with de novo intracranial aneurysm formation in clinical case reports, but this phenomenon is not widely studied. We performed bilateral carotid ligation (n=9) in rabbits to simulate carotid occlusion, and sham surgery (n=3) for control. Upon euthanasia (n=3 at 5 days, n=6 at 6 months post ligation, and n=3 at 5 days after sham operation), vascular corrosion ca...

BACKGROUND AND PURPOSE Intracranial aneurysms have been induced in mice, rats, rabbits, and primates through carotid artery ligation. We reviewed our experience with RCCA ligation to quantify the rate of aneurysm formation in rabbits. MATERIALS AND METHODS In 30 consecutive New Zealand white rabbits, the RCCA was ligated during surgery to create elastase-induced aneurysms. The basilar artery ...

RATIONALE Coronary artery fistula (CAF) is characterized by an abnormal communication of a coronary artery with a cardiac chamber or a great vessel bypassing the capillary bed. Surgical closure of large or symptomatic CAF is the gold standard treatment. However the previously closed CAF still has the possibility to reopen. Superior vena cava syndrome (SVCS) is defined as a condition that occurs...
