Early complications and results of surgery for ruptured intracranial aneurysms

A personal prospective study has been carried out on 91 consecutive patients undergoing direct surgery for aneurysms of the anterior Circle of Willis. The protocol particularly involved maintaining normotension for each patient during surgery, and operating on all patients in Grades I, II, and III and on those patients in Grades IV and V suffering from coincidental hydrocephalus or intra-cranial haematoma. The results are discussed with particular regard to earlier complications following surgery.
