Use of a Radial Artery Graft in STA-MCA Anastomosis and Other Recent Improvements in Reconstructive Surgery (&lt;Special Issues&gt;Reconstruction of Cerebral Artery)

A new method was developed to maintain a bloodless microscopic operative field for superficial temporal artery-middle cerebral artery (MCA) anastomosis surgery. A silicone suction tube with multiple holes is placed circumferentially under the reflected dural flaps around the craniotomy. Blood and irrigated saline are continuously aspirated by the tube. Use of this method in nine patients significantly reduced the mean MCA trapping time (24.0 ± 2.8 min) compared with nine patients treated using the conventional method (30.1 ± 4.6 min). MCA trapping time is shortened because the surgery is not interrupted for manual suctioning of bloody cerebrospinal fluid.

We present the use of radial artery graft for bypass of the proximal superficial temporal artery to the proximal middle cerebral artery. Six adult cadaver sites were used bilaterally. After apterional incision, 2x2-cm minicraniectomy was performed which began 2 cm behind the zygomatic process of the frontal bone. The superficial temporal artery was transsected before exposing the zygomatico-orbital artery branch. The proximal side of the radial artery graft was anastomosed end-to-end to the proximal superficial temporal artery and the distal side end-to-side to the proximal middle cerebral artery. The mean calibers of the proximal superficial temporal artery and largest trunk of the middle cerebral artery were 2.25+/-0.35 mm and 2.3+/-0.3 mm, respectively. The average graft length was 85+/-5.5 mm. We conclude that such bypasses are simpler than proximal middle cerebral artery revascularization using long vein grafts. This method proves that the caliber of the proximal superficial temporal artery is more suited to providing sufficient flow than the distal superficial temporal artery, and the graft is short. Such bypasses to the middle cerebral artery may be an alternative to those from the distal superficial temporal artery or extracranial carotid artery.

Proximal STA to proximal PCA bypass using a radial artery graft by posterior oblique transzygomatic subtemporal approach

The aim of the present study was to investigate the use of a radial artery graft (RAG) for bypass of the proximal superficial temporal artery (STA) to proximal posterior cerebral artery (PCA) by posterior oblique transzygomatic subtemporal approach as an alternative to the external carotid artery (ECA) to PCA anastomosis. We conducted an anatomical and technical study at a university hospital. Five adult cadaveric specimens were dissected. A preauricular vertical skin incision was used. The trunk of STA was identified. A 30 degrees oblique posterior zygomatic arch osteotomy and microcraniotomy was performed. The dura of the middle cranial fossa was then opened. The temporal lobe was retracted, the interpeduncular and ambient cisterns were opened, and the P2 segment of the PCA was exposed. The proximal side of the RAG was anastomosed with the proximal STA and the distal side was anastomosed with the P2 segment. The mean caliber of the proximal STA was 2.25 +/- 0.35 mm. The mean diameter of the P(2) was 2.2 +/- 0.2 mm. The average length of the RAG was 56 +/- 3.2 mm. The mean caliber of the proximal and the distal sides of the graft was 2.5 +/- 0.25 mm and 2.3 +/- 0.15 mm, respectively. Because the proximal STA to proximal PCA bypass uses a short RAG and their calibers are over 2 mm, this bypass technique can provide a sufficient blood flow and may be a reasonable alternative over ECA to PCA bypass using long grafts.
