Cerebral revascularization using cadaveric vein grafts

Comparative efficacy of autologous versus cadaveric saphenous vein grafts in cerebral revascularization surgery

“…12 Our preliminary report on the use of cadaveric SVGs in cerebral revascularization surgery noted a 100% short-term graft patency rate. 19 In the present analysis, at a median follow-up of 2.2 months (IQR 0.2-29.1), 13 (86.7%) of 15 cadaveric SVGs were patent compared with 26 (68.4%) of 38 autologous SVGs (p = 0.30), and Kaplan-Meier estimates showed no difference in the bypass patency rate over time between SVG types (p = 0.58). In addition, of the 13 cadaveric SVGs patent beyond the 1st postoperative day, 13 (100%) were patent at the last follow-up.…”

“…Preliminary outcome data from 3 (20.0%) of the 15 cadaveric cases have been previously reported. 19 Bypass procedures were performed for the purpose of either flow augmentation for steno-occlusive atherosclerotic disease (14 cases) or flow replacement during complex aneurysm (38 cases) or tumor (1 case) surgery. Between autologous and cadaveric SVG recipients, there were no statistically significant differences in age (p = 0.50), sex (p > 0.99), history of smoking (p = 0.75), hypertension (p > 0.99), diabetes mellitus (p = 0.13), or indication for bypass (p = 0.27; Table 1).…”

“Squeeze Maneuver” Assisted by Indocyanine Green Videoangiography: Simple Technique to “Resuscitate” Partially Occluded Bridging Veins During Microneurosurgical Operations

“…When the integrity of the vein wall is damaged, on the basis of the size of the defect, methods for definitive repair include wrapping, microsuture, venous reconstruction using the silicone tubing technique or saphenous vein bypass graft, and vein anastomosis. 1,[15][16][17][18][19][20] However, all of these procedures are not useful for collapsed veins with uninjured walls. In these circumstances, a profuse irrigation with isotonic saline solution may be useful to rehydrate the vein wall in order to restore its normal diameter.…”
