Vasodilator proteins: role in delayed cerebral vasospasm.

abstract：BACKGROUND AND PURPOSE:Limited data exist on the frequency and outcome of carotid artery disease in Pakistan. Such information would help guide the usefulness of screening for the condition in this low-middle income health care setting. METHODS:A prospective, descriptive study was conducted among 3 large teaching hosp...
