Subarachnoid hemorrhage or intracerebral hemorrhage caused by rupture of a saccular intracranial aneurysm (sIA) is often fatal and causes significant loss of productive live years in addition to significant mortality. Around 3.5 % of the middle aged otherwise healthy population carries unruptured sIAs. Many sIAs never rupture, and since their prophylactic ...

Cryptogenic (of unknown cause) ischaemic strokes are now thought to comprise about 25% of all ischaemic strokes. Advances in imaging techniques and improved understanding of stroke pathophysiology have prompted a reassessment of cryptogenic stroke. There is persuasive evidence that most cryptogenic strokes are thromboembolic. The thrombus is thought to originate ...

A growing health problem, venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), requires refined diagnostic and therapeutic approaches. Neutrophils contribute to thrombus initiation and development in experimental DVT. Recent animal studies recognized neutrophil extracellular traps (NETs) as an important scaffold supporting thrombus stability. However, the hypothesis ...

Mitral valve regurgitation together with aortic stenosis is the most common valvular heart disease in Europe and North America. Mechanical and biological prostheses available for mitral valve replacement have significant limitations such as the need of a long-term anticoagulation therapy and failure by calcifications. Both types are unable to remodel, ...

Although coil embolization is known to prevent rebleeding from acutely ruptured cerebral aneurysms, the underlying biological and mechanical mechanisms have not been characterized. We sought to determine if microcoil-dependent interactions with thrombus induce structural and mechanical changes in the adjacent fibrin network. Such changes could play an important role in ...

Surgical clipping for upper basilar artery (BA) trunk aneurysms has become less common since the popularization of endovascular therapy. However, when endovascular therapy is not feasible, direct open surgery is still the treatment of choice. The anterior transpetrosal approach (ATP) is most often used to safely treat these aneurysms. We ...

Penile transplantation may provide improved outcomes as compared to autogenous phalloplastic reconstruction. The optimal approach to vascularizing penile allografts is unknown. In penile replantation typically only the dorsal arteries are repaired, but utilizing the cavernosal and external pudendal arteries may improve erectile function and shaft skin perfusion, respectively. The authors ...

Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease affecting 4-8% of men older than 60 years. No pharmacologic strategies limit disease progression, aneurysm rupture, or aneurysm-related death. We examined the ability of rapamycin to limit the progression of established experimental AAAs. AAAs were created in 10-12-week-old male C57BL/6J mice ...

Aortic dissections originating in the ascending aorta and descending aorta have been classified as type A and type B dissections, respectively. However, dissections with intimal flap extension into the aortic arch between the innominate and left subclavian arteries are not accounted for adequately in the widely used Stanford classification. This ...

Flow diversion is a new endovascular technique developed for treatment of intracranial aneurysms. It is based on stent-induced modification of blood flow within and around an aneurysm inflow zone, leading to gradual intra-aneurysmal thrombosis and subsequent atrophy, while preserving flow into the parent vessel and perforating branches. Flow-diversion technique is ...

Carotid artery stenting has been advocated as an effective alternative to carotid endarterectomy. Periprocedural embolization of debris during endovascular treatment of carotid artery disease may result in neurological deficit. Different strategies are being developed and evaluated for their ability to minimize the clinical embolic risk. Distal filter devices, proximal and ...

Treatment of giant posterior circulation aneurysms, via endovascular or microsurgical approaches, carries a high risk of morbidity and mortality. While flow-diverting stents (FDSs) represent a potent therapy for endovascular reconstruction of complex aneurysms, they are also associated with novel complications for which effective salvage techniques are lacking. We present a ...

Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across ...

Arterial restenosis frequently develops after open or endovascular surgery due to intimal hyperplasia. Since tissue transglutaminase (TG2) is known to involve in fibrosis, wound healing, and extracellular matrix remodeling, we examined the role of TG2 in the process of intimal hyperplasia using TG2-null mice. The neointimal formation was compared between ...
