Arterial bifurcations in the circle of Willis were observed three-dimensionally in 44 cases of cerebral aneurysm and 45 control cases. Variations of the circle of Willis were also studied in relation to cerebral aneurysm. The following results were obtained : 1. Aneurysm always occurred at the apex of the cerebral arterial bifurcation where axial flow in the parent artery immediately proximal t...

Aneurysm of extracranial carotid artery is an uncommon clinical disease and that presenting as a ruptured aneurysm is extremely rare. This entity represents a challenge to treatment strategy. A 54 year old hypertensive male presented with painful, pulsatile mass in left neck. Duplex scan revealed the ruptured left carotid artery at its bifurcation. Angiogram depicted clear picture of ruptured c...

BACKGROUND Splenic artery aneurysms are the commonest visceral and third most common abdominal artery aneurysms, having a strong association with both pregnancy and multiparity. Here we report possibly the first case of a giant splenic artery aneurysm in association with a smaller portal vein aneurysm, in a woman who had never conceived, leading to non-cirrhotic portal hypertension. CASE PRES...

Infective coronary artery aneurysm is extremely rare and ruptured aneurysm is life-threatening. We report a case of ruptured coronary artery aneurysm, which was successfully treated by the patch closure technique and coronary artery bypass grafting. Pathological examination revealed purulent inflammation in the aneurysmal wall. Prompt diagnosis and appropriate treatment were essential.

We report a hybrid surgery including endovascular aneurysm repair and debranching procedures to treat a patient with a complex right subclavian artery aneurysm. The patient was a 70-year-old woman who presented with dry cough and hoarseness. The aneurysm was characterized by the absence of a proximal neck, and involvement of the origin of the right vertebral artery. She underwent carotid-verteb...

We herein report a case of hemobilia caused by a hepatic artery aneurysm. A 40-year-old male patient with a history of Behçet's disease with a thrombus hanging out of the papilla of Vater had a large hepatic aneurysm in angiography. The hepatic artery feeding the aneurysm was embolized. Endovascular treatment can treat patients with hepatic artery aneurysms caused by Behçet's disease.

Objective and Importance—Vertebrobasilar artery aneurysms can be very challenging to treat and are preferentially dealt with using endovascular techniques, since they are associated with lower risk than surgical clipping. Small aneurysms located on perforating arteries can pose problems though, as their dimensions may not be favorable for coiling and leave the endovascular surgeon without many ...

Splenic artery aneurysms are rare but important vascular lesions that constitute approximately 60% of all visceral arterial aneurysms. Splenic artery is the third most common localization of intraabdominal aneurysm formation. Rupture is the main complication that occurs in 3%-10% of the cases. We describe a case with a proximal splenic artery aneurysm. To preserve splenic function and reduce th...

A subclavian artery aneurysm is rare. We report the case of a 61-year-old man with a history of hypertension and angina pectoris who was diagnosed with an atherosclerotic aneurysm of the left subclavian artery. An incidental computed tomography scan revealed a 37-mm saccular aneurysm adjacent to both the proximal left subclavian artery and the distal aortic arch. He underwent an aneurysmectomy ...
