It is the key step of the cerebral aneurysm recognition system to locate the cerebral aneurysm accurately and fast onto the image. A new detection method of cerebral aneurysm, which is based on the improved thinning algorithm, is proposed after analyzing the morphological characteristics of cerebral aneurysm fully in the paper. In this new detection method, the improved OPTA algorithm is used t...

Splenic artery aneurysm is the third most common location of intra-abdominal aneurysms. Giant splenic artery aneurysm is rarely seen and is at a high risk of rupture. Location and size of the splenic artery aneurysm determine the likelihood of rupture. A case of giant splenic artery aneurysm in a 35-year-old woman is reported. She presented with upper gastrointestinal bleeding. She had splenome...

Volume representations of blood vessels acquired by 3D rotational angiography are very suitable for diagnosing an aneurysm. We presented a fully-automatic aneurysm labelling method in a previous paper. In some cases, a portion of a “normal” vessel part connected to the aneurysm is incorrectly labelled as aneurysm. We developed a method to detect and correct these erroneous border areas. Applica...

Brachiocephalic artery aneurysm with concomitant coronary artery aneurysm is rare. We describe a case of a patient with a history of prosthetic graft placement following resection of an abdominal aortic aneurysm and was subsequently found to have a brachiocephalic artery aneurysm. After surgical correction of the brachiocephalic aneurysm, postoperative coronary arteriography demonstrated corona...

We modified the elastase-induced aneurysm model by use of a simple surgical technique in rabbits. A temporary arcuated aneurysm clip was placed at the origin of the right common carotid artery (RCCA), ascertaining the inner edge of the clip blade on the juncture of the RCCA and right subclavian artery (RSCA), and the elastase-induced aneurysm procedure was undertaken. We found elastase and loca...

Results One patient with subclavian artery aneurysm underwent resection of the aneurysm and subclavian-axillary bypass surgery with brachial embolectomy using a polytetrafluoroethylene (PTFE) graft; whereas the other patient underwent resection of the aneurysm and subclavian-axillary bypass surgery with saphenous vein graft. In addition to resection of the aneurysm, three out of 6 patients with...

conclusions although propofol remains a standard agent for such types of surgeries, lidocaine proved equally effective and coupled with its low cost, minimal side effects and omission of other hypnotic agents was a plausible induction agent and a maintenance drug in the selected cases. case presentation lidocaine was applied as the sole anaesthetic for induction and maintenance during aneurysm ...

BACKGROUND AND PURPOSE Children with brain aneurysms may be at higher risk than adults to develop new or enlarging aneurysms in a relatively short time. We sought to identify comorbidities and angiographic features in children that predict new aneurysm formation or enlargement of untreated aneurysms. MATERIALS AND METHODS Retrospective analysis of the University of California-San Francisco Pe...

OBJECTIVE To establish, in a case-control study, the early mortality and long-term survival after surgical correction of sealed rupture abdominal aortic aneurysm, compared to controls who underwent standard, nonruptured abdominal aortic aneurysm repair. PATIENTS AND METHODS From January 1992 to December 2002, 465 patients underwent infrarenal abdominal aortic aneurysm repair. Of those, 13 had...

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 ...
