Case Reports[Surgical treatment of giant cerebral arteriovenous malformations].
Despite advances in the surgical management of cerebral arteriovenous malformations (AVMs), giant (AVMs (greater than 5 cm] are still considered unsuitable for direct surgical resection by most neurosurgeons. Some of the lesions are being treated with embolization, or embolization followed by surgical excision. Embolization alone is not curative and carries potential risks of neurological deficit as well involves multiple procedures. ⋯ At least in one report dealing with combined treatment of seven giant AVMs, some authors stressed that preoperative embolization did not significantly alter the blood flow and, hence, potential of bleeding at the time of operation. Blood loss has not been a significant problem in our experience. When there is an associated aneurysm, it should be treated prior to or at the time of excision of the malformation.

A case of acute pulmonary edema after subarachnoid hemorrhage is presented. A supra and infratentorial arteriovenous malformation was revealed by serial cerebral angiography. Sequential chest films documented regression of both, pulmonary edema and cardiac enlargment. The literature is reviewed and a possible physiopathology is discussed.
