Intraoperative sonographic assessment of graft patency during extracranial-intracranial bypass.
Extracranial-intracranial (EC-IC) bypass may be necessary to facilitate treatment of unclippable posterior circulation fusiform aneurysms. Although intraoperative digital subtraction angiography (DSA) allows assessment of graft patency, this technique, because of difficulties inherent in performing selective catheterization and angiography in the operating room, has limitations. Duplex sonograp...
متن کاملExtracranial-intracranial bypass grafts.
An extracranial-intracranial bypass graft was established in 16 dogs. The graft was routed deep in the lateral pharyngeal space as opposed to the subcutaneous course in front of the ear, which may be hazardous. Of 10 common carotid-middle cerebral arterial bypass grafts three were still patent four and a half, six, and 11 months postoperatively. The remaining seven arterial and six venous bypas...
متن کاملThe extracranial/intracranial bypass study.
PHYSICIANS IN their eagerness to help patients often become enthusiastic or supportive of a particular therapy based on their own limited experience or on the anecdotal experiences of others before there is clear evidence that a particular treatment is useful or effective. Many treatments are proposed and carried out often at great expense and sometimes with considerable risk long before there ...
متن کاملMagnetic resonance angiographic assessment after extracranial-intracranial bypass surgery.
Extracranial-intracranial (EC-IC) bypass operation may be performed to augment the distal cerebral circulation. The bypass patency is usually assessed postoperatively with conventional cerebral angiography. Six patients are reported in whom the bypass patency was assessed using magnetic resonance angiography (MRA): Two had intracavernous carotid aneurysms, three had base of skull tumours encomp...
متن کاملCortical blood flow during extracranial-intracranial bypass surgery.
Cortical blood flow was evaluated at the time of surgery with a thermal diffusion flow probe in 25 extracranial-intracranial bypass operations. The procedures were performed 14 times for carotid occlusion, 6 times for inaccessible carotid stenosis, on 3 occasions for middle cerebral occlusion, once for basilar occlusion and once for middle cerebral stenosis. Fifty-seven different cortical regio...
