Autogenous artery and vein grafts in common carotid-supraclinoid carotid anastomoses.
Microsurgical techniques employing either autogenous saphenous arterial grafts or venous grafts were used for common carotid-supraclinoid carotid anastomoses (CC-SCAs) in dogs. The CC-SCA provides a large volume of blood to a major vessel supplying the brain. Within 10 to 14 days postoperatively, angiography and postmortem examination showed arterial patency in 9 (69%) of 13 dogs and venous patency in 2 (25%) of 8 dogs. The discrepancy in patency between the arterial and venous grafts may be the result of the differences in construction of arteries and veins, technical failure, shear stress, turbulence, and/or boundary layer separation. The application of autogenous arterial grafts (i.e., radial, hypogastric) in humans seems justified.
