Biochemical adaptation of venous patches placed in the carotid circulation.

The influence of venous patching on luminal prostacyclin (PGI2) and thromboxane A2 (TBX) production of endarterectomized arteries was studied in a canine model. Fifteen dogs underwent bilateral common carotid endarterectomies. In each dog, one artery was closed primarily and the contralateral artery was closed by vein-patch angioplasty. At six and 12 weeks… (More)
