Stenoses in the posterior cerebral circulation often have a bad prognosis. There may be a high rate of morbi-mortality and recurrences of ischemic events in this territory. Currently we have no evidence or consensus about what the best pharmacological option is for these patients. We report a case of a 75 year old woman with sever stenosis of the proximal part of the basilar artery with recurrent transient ischemic events unresponsive to different combinations of antiagregant and anticoagulant treatments. A percutaneous transluminal angioplasty with the addition of a stent in the basilar artery was performed successfully. At present, there are few studies and a low number of patients treated by this technique. The results obtained are promising, with a low rate of morbi-mortality, the most frequent complications being embolization of the atherosclerotic lesion, dissection, rupture or restenosis.

Delayed rupture of intracranial aneurysms after endovascular treatment is a rare but serious complication. We report the first documented case of late aneurysmal rupture following treatment with a Contour intrasaccular device. A patient in their 60s with a basilar tip aneurysm underwent endovascular treatment using a 14-mm Contour device.

The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

Background: Intravascular injection of liquid adhesive hemostats is a rare but serious complication that can result in cerebral thromboembolism.
Observations: A 64-year-old female underwent orbitozygomatic craniotomy for posterior communicating artery aneurysm clipping with the routine use of a flowable hemostatic agent during extradural dissection. After placement of the aneurysm clip, flow was confirmed through the parent vessel and nearby branches.

Basilar artery perforator aneurysms (BAPAs) are rare and may be occult on initial imaging due to their small size and susceptibility to intermittent thrombosis.1 2 Conventional treatments for aneurysms (eg, clipping or coiling) have proved challenging.3 Recently, endovascular electrocoagulation has been shown to be effective for BAPAs.
