Aneurysm of the pulmonary artery is a rare condition in animals, and to our knowledge it has never been reported association with neoplasia. This report describes case an adult female sheep “Churra Galega Bragançana” breed aneurysm associated lung cancer (ovine adenocarcinoma).

 Abstract Background: Renal insufficiency is a potential complication after infrarenal abdominal aortic aneurysm repair and is a significant risk factor for postoperative mortality and morbidity. The aim of this study was to analyze the effect of this risk factor, before and during operation. Methods: In this prospective study, between 2003 and 2006, 45 patients underwent repair of an infrarena...

OBJECTIVE Cases of a ruptured pericallosal artery aneurysm with a high risk of intraoperative premature rupture and technical difficulties for proximal vascular control require a technique for the early and safe establishment of proximal vascular control. METHODS A combined pterional or subfrontal approach exposes the bilateral A1 segments or the origin of the ipsilateral A2 segment of the an...

BACKGROUND Prospective observation of hemodynamic changes before and after formation of brain aneurysms is often difficult. We used a vessel surface repair method to carry out a retrospective hemodynamic study before and after aneurysm formation in a ruptured aneurysm of the posterior communicating artery (RPcomAA) and an unruptured aneurysm of the posterior communicating artery (URPcomAA). M...

Although wall shear stress (WSS) has long been considered a critical indicator of intracranial aneurysm rupture, there is still no definite conclusion as to whether a high or a low WSS results in aneurysm rupture. The reason may be that the effect of WSS direction has not been fully considered. The objectives of this study are to investigate the magnitude of WSS (|WSS|) and its divergence on th...

There are few observation papers regarding the natural history of an aneurysm. We report on a case of a completely occluded middle cerebral artery (MCA) aneurysm. A 47-year-old female patient presented with a headache and was diagnosed with rupture of a right MCA aneurysm. Due to a high risk of direct neck clipping, she received conservative treatment after craniotomy and wrapping of her aneury...

SUMMARY A replica of a lethal wide-necked basilar artery aneurysm was created by casting a deceased patient's brain vessels and then placing the replica in a circuit of pulsating optically clear non-Newtonian fluid. Individual fluid slipstreams were opacified with isobaric dyes, and images were recorded on film. Studies were completed on the vascular replica, then were repeated, first after pla...

Splenic artery aneurysm, one of the most common visceral aneurysms, accounts for 60% of all visceral aneurysm cases. Open surgery is the traditional treatment for splenic artery aneurysm but has the disadvantages of serious surgical injuries, a high risk of complications, and a high mortality rate.We report a case who was presented with splenic artery aneurysm. A 54-year-old woman complained of...

BACKGROUND AND PURPOSE The main issue with use of a liquid embolic agent is one of safety. To determine and improve the efficacy of potential neuroendovascular treatment regimens, particularly the use of liquid embolic agents, we evaluated the changes in aneurysm flow dynamics resulting from alterations of parent vessel flow. METHODS We created silicone replicas of a laboratory-created aneury...
