Mattress anastomosis in micro vascular reconstruction: technical note

Superficial temporal artery-to-middle cerebral artery (STA-MCA) anastomosis is a common procedure for neurosurgeons. The surgery necessarily requires accurate and speedy manipulation of microscope, for which a specific training is needed. Unexpected bypass occlusion sometimes happen during surgery. Generally, conventional interrupted or continuous suture has been used for vascular anastomosis, despite various ideas have been attempted in the other surgery fields. We propose a horizontal mattress suture technique for intracranial microvascular bypass surgery. This is the first report ever published on intracranial vascular anastomosis. We had four patients of STA-MCA bypass surgery with "mattress anastomosis" from March to May of 2012. During the procedure, there was no bypass occlusion and good patency was confirmed in all cases. Intimae of the recipient and the donor blood vessel contact each other precisely with this technique. Although a long-term assessment of patency is needed, it is useful for the intracranial bypass surgery.

Complications of Middle Cerebral Artery-Superficial Temporal Artery Anastomosis

Microvascular bypass surgery for occlusive cerebral vascular disease has aroused considerable interest in the past decade. This interest has been accompanied by considerable experience. Improvements in the technique, together with experience, has refined the indications for the procedure and made us aware of the complications of bypass surgery for occlusive cerebral vascular disease.

Microvascular bypass surgery. Part 2: physiological studies.

Intraoperative electromagnetic blood flow measurements were recorded in 15 patients undergoing extracranial-intracranial arterial bypass surgery. The initial average blood flow of 28.2 cc/min supplies 8.4% of the expected flow from one internal carotid artery. Blood flow probably increases postoperatively, as evidenced by angiographic enlargement of the bypass and its recipient cortical arteries.

Microvascular bypass surgery. Part 1: anatomical studies.

Microvascular anatomical studies were performed to ascertain the most suitable cortical vessel for extracranial-intracranial arterial bypass (EIAB). The three most commonly used cortical areas (the tip of the frontal lobe, the tip of the temporal lobe, and the area at the angular gyrus) were examined in detail. Because of their accessiblity and size, the cortical arteries in the area of the angular gyrus offer the most suitable location for creating an EIAB.
