Ruptured intrasellar superior hypophyseal artery aneurysm presenting with pure subdural haematoma. Case report.

SUMMARY: Subdural haemorrhage from a ruptured intracranial aneurysm is a well-known entity when associated with subarachnoid haemorrhage. However, haemorrhage confined only to the subdural space is rare because there are limited anatomical sites where extravasation can be purely subdural. We report the rare case of a patient who suffered pure subdural haematoma after the rupture of a left superior hypophyseal artery aneurysm located within the sella turcica. The patient was treated with endovascular coil embolization of the aneurysm. Angiography immediately after treatment and one month later revealed complete obliteration of the aneurysm. Six months after treatment, the patient remained symptom free.

Use of the transverse cervical artery with indwelling shunt for subclavian-vertebral bypass.

A patient presented with vertebrobasilar symptoms and a complex pattern of cerebrovascular occlusions that required direct bypass to the vertebral artery. A branch of the thyrocervical trunk was used with a temporary indwelling shunt; the outcome was successful.
