In most previous studies, ischemia-reperfusion (I/R) induced vascular injury referred to injury in the tissue or blood vessel that was actually subjected to I/R. However, less attention has been focused on remote vascular injury that might be caused by cardiac I/R. In the present study, we aimed to assess whether ...

Emerging evidence suggests that protease-activated receptors-1 and -2 (PAR1 and PAR2) can signal together in response to proteases found in the rapidly changing microenvironment of damaged blood vessels. However, it is unknown whether PAR1 and PAR2 promote or mitigate the hyperplastic response to arterial injury. Using cell-penetrating PAR1 pepducins and ...

The incidence of ischemic stroke reported after blunt vertebral artery injury is lower than that reported after blunt carotid artery injury. Unlike the carotid arteries, the vertebral arteries receive collateral blood flow through ascending cervical branches in addition to a convergent arterial supply with the contralateral vertebral artery. We hypothesize ...

Neonatal stroke encompasses a range of focal and multifocal ischaemic and haemorrhagic tissue injuries. This review will concentrate on focal brain injury that occurs as a consequence of arterial infarction, most frequently the left middle cerebral artery, or more rarely as a consequence of cerebral sinus venous thrombosis (CSVT). Both ...

Carotid artery injury during endonasal surgery is the most feared and catastrophic complication. Internal carotid artery injury is more frequent during skull base surgery, and risk factors include acromegaly, previous revision surgery, and prior radiotherapy and bromocriptine therapy. Nasal packing is frequently used to gain hemostasis, often resulting in vascular ...

Pseudoaneurysms are vascular injuries resulting from a rupture of the vessel walls with blood extravasation into perivascular tissues. Proper treatment is required to prevent rupture and intense bleeding. This article reports a case of pseudoaneurysm of the facial artery that evolved to a late complication, presenting dehiscence of suture and ...

Fenestration in A1 segment of anterior cerebral artery is a rare entity. Treatment of aneurysms derived from a fenestrated artery may be more challenging because the fenestrations provide specific difficulties. A thorough radiologic work-up driven by high clinical suspicion is needed. Endovascular treatment, although it has been tried only once,(7) ...
