Postoperative assessment of cerebral blood flow in subarachnoid haemorrhage by means of 99mTc-HMPAO tomography.

Regional hypoperfusion is a very frequent complication of subarachnoid haemorrhage (SAH), being related to vasospasm in the majority of cases. Twenty-six patients who were admitted for SAH underwent follow-up with technetium-99m hexamethylpropylene amine oxime single photon emission tomography (SPECT) 3 and 8 days after surgery. Fifteen patients of these had one more examination 15 days after surgery.

Morbidity after aneurysmal subarachnoid hemorrhages is proceeding from many factors; ischemic etiology is underestimated and frequently thought to be vasospasm related only. Other undoubted mechanisms are in the setting of ischemic disorders after ruptured aneurysms. The management of these disorders is relevant of new calcium blockers.
