What are the most serious complications following subarachnoid hemorrhage from aneurysm rupture?

 

The most serious sequela of subarachnoid hemorrhage is re-bleeding. The incidence of re-bleeding following aneurysm rupture is approximately 15% in the first week, and approximately 10% in the second week. Morbidity and mortality following re-bleed is very great and has motivated the trend towards early intervention following aneurysm rupture.

 

Cerebral vasospasm is also a major cause of morbidity and mortality following subarachnoid hemorrhage. Symptomatic brain ischemia from vasospasm occurs in 15–35% of patients. Angiographic evidence of vasospasm occurs in as many as 70% of patients. Vasospasm may lead to cerebral infarction.

 

Subarachnoid hemorrhage often also leads to hydro-cephalus and may result in dangerously elevated intra-cranial pressure.
