Case Reports
[An Endovascular Approach for Ruptured Aneurysms of the Basilar Trunk Perforating Artery].
Aneurysms of the basilar trunk perforating artery are rarely described in the literature. Only 13 cases have been reported previously. ⋯ Microsurgical clipping or wrapping has the disadvantage of the deep and narrow operative area and the difficult skull-base technique. Here, we report a case of basilar trunk perforating rupture aneurysm and its treatment with endovascular coil embolization.

Cerebral venous sinus thrombosis after mild head trauma without skull fracture or intracranial hematoma is exceptionally rare. We describe an unusual case of progressive intracranial hypertension due to superior sagittal sinus thrombosis following mild head trauma. A 17-year-old boy presented with nape pain a day after a head blow during a gymnastics competition (backward double somersault). ⋯ After 7 days of conservative treatment, his symptoms resolved completely, and he was discharged from the hospital. Follow-up MR venography performed on Day 55 showed complete recanalization of the superior sagittal sinus. The exact mechanism of sinus thrombosis in this case is not clear, but we speculate that endothelial damage caused by shearing stress because of strong rotational acceleration or direct impact to the superior sagittal sinus wall may have initiated thrombus formation.
