The complication of the posterior fossa surgery is seldom described in the literature. The purposes of this retrospective study are to draw attention to the potential complications associated with posterior fossa surgery and to critically review the predisposing factors that might influence the complication rate. ⋯ Posterior fossa surgery involves greater morbidity and mortality and has a wider variety of complications than surgery in the supratentorial compartment. These complications may be avoided by careful perioperative planning, strict adherence to aseptic technique, meticulous microsurgical dissection, proper wound closure, and the judicious use of prophylactic agent. A thorough understanding of the patient's history, neurological findings, imaging studies, operative anatomy, as well as all potential adverse events associated with the procedure is also essential to minimize complications.

Cerebral vasospasm is a widespread and potentially treatable complication after aneurysmal SAH. Aggressive treatment often includes hemodynamic augmentation, although the exact mechanism by which such therapy leads to improved cerebral blood flow and reduced neurologic deficits is incompletely established. This case report is only the second to provide compelling evidence that hypertension can lead to direct dilation of vasospastic arteries, thereby providing valuable insight into its potential mechanism. ⋯ The present case illustrates that extreme hypertension can lead to direct dilation of vasospastic arteries and suggests that hypertensive-type hemodynamic therapy may act not only through increasing the pressure gradient across vasospastic arteries but also via direct induction of arterial vasodilation.

Endovascular coil treatment is being used increasingly as an alternative to clipping for some ruptured intracranial aneurysms. The relative benefits of these 2 approaches have yet to be fully established. The aim of this study was to compare the clinical outcome, resource consumption, and cost-effectiveness of endovascular treatment vs surgical clipping in a developing country. ⋯ Patients with aneurysmal SAH whom we judged to require coiling had higher charges than patients who could be treated by clipping. The benefits of apparent decrease in length of stay in the endovascular group were offset by higher procedure price and cost of consumables. There was no significant difference in clinical outcome at 6 months. We have proposed a risk scoring system to give guidelines regarding the choice of treatment considering size of aneurysm and resource allocation.
