Should we treat aneurysms in perforator arteries from the basilar trunk? Review of 49 cases published in the literature and presentation of three personal cases.
Authors: Chau Y, Sachet M, Sédat J Abstract Basilar trunk perforator artery aneurysms are rare. Their diagnosis and treatment are difficult, controversial, and challenging. Analysis of 52 cases (49 documented in the literature and three personal cases) clearly shows a re-bleeding rate of 15% in patients whose aneurysm has not been occluded and 0% in treated patients ( p

Severe cerebellar hemorrhage following transverse sinus stenting for idiopathic intracranial hypertension.
We report a severe adverse event occurring in the course of a cohort study (ISRCTN13784335) aimed at measuring the efficacy and safety of venous stenting in the treatment of patients with medically refractory idiopathic intracranial hypertension (IIH). The patient was a 41-year-old woman who was not overweight, who presented with severe headache, grade 1 bilateral papilledema and transient tinnitus, refractory to medical treatment. Right transverse sinus stenting was successfully performed. Following surgery, the patient's state of consciousness decreased acutely with rapid and progressive loss of brainstem reflex. CT scan...

Endovascular treatment for acute basilar thrombosis via a transradial approach: Initial experience and future considerations.
We report our initial multi-institutional experience using primary radial access in the treatment of acute BAO in nine consecutive cases. Technical success defined as a TICI score of 2B or 3 was achieved in 89% of cases. Average puncture to revascularization time was 35.8 minutes. There were no complications related to radial artery catheterization. We contend radial access should potentially be considered as the first-line approach given inherent advantages over femoral access for mechanical thrombectomy for BAO.

Combined use of stent-retriever and aspiration thrombectomy for cerebral venous sinus thrombosis involving the straight sinus: A case report.

A 42-year-old woman presented with a progressive disturbance in consciousness, and diagnosed CVST in the straight sinus (SS). Recanalization of SS was achieved by emergent thrombectomy using aspiration catheter and stent-retriever system, and her level of consciousness improved immediately.

Successful presurgical endovascular management of venous sinus thrombosis associated with high-grade cerebral arteriovenous malformation: A case report.
We report a case of a 39-year-old man presenting with a high-grade left parieto-occipital arteriovenous malformation (AVM) complicated by superior sagittal sinus (SSS) stenosis, seven years after the first presentation. Magnetic resonance imaging revealed a newly developed perilesional edema. Venous sinus stenosis acutely progressed to occlusion and induced multiple intracerebral hemorrhages. An emergent balloon venoplasty of the SSS successfully recanalized the thrombosed sinus. Further, multistage transarterial nidus embolization was performed followed by surgical resection, resulting in a complete eradication of the lar...

Cardio-cephalic neural crest syndrome: A novel hypothesis of vascular neurocristopathy.
Authors: Komiyama M Abstract A novel hypothesis proposes that "cardio-cephalic neural crest (NC) syndrome," i.e. cephalic NC including cardiac NC, contributes to the concurrent occurrence of vascular diseases in the cardio- and cerebrovascular regions. NC is a transient structure present in early embryogenesis. Cephalic NC provides mesenchymal cells to the vascular media in these regions. Concurrent cardio- and cerebrovascular lesions have been reported in PHACE syndrome, ACTA2 mutation syndrome, and less frequently in the spontaneous occlusion of the circle of Willis (so-called moyamoya disease).
