Intraoperative angioscopy after carotid endarterectomy.
The angioscopic evaluation of the carotid bifurcation has proved valuable for intraoperative quality control after carotid endarterectomy (CEA). From January 1989 to July 1990, intraoperative angioscopy was performed in 196 patients undergoing CEA. We used a 2.2, 2.8 or 3.6 mm angioscope inserted at the end of the CEA through the remaining opening in the suture line. The angioscopic findings were classified as follows: I--no pathology (68%), II--thrombi, smaller debris, suture irregularities (29%), III--intima flap, endoscopic removal (3%), IV--intima flap, surgical redo (3%). Our results support the practicability and importance of intraoperative angioscopy for surgical decision making. It is possible to rinse out thrombi or remove remaining debris using flexible forcepy, under direct visual control. There were no significant complications related to the angioscopic procedure.
