intraoperative angioscopy
Direct visual examination of vessel interior using a flexible endoscope during surgery.
Full Definition
Intraoperative angioscopy involves the use of a flexible fiberoptic endoscope to directly visualize the interior of blood vessels during surgical procedures. This technique allows surgeons to assess the quality of endarterectomy endpoints, identify retained plaque or thrombus, and evaluate anastomotic sites in real-time. While less commonly used than completion angiography, angioscopy provides unique advantages in certain situations, particularly for ensuring complete plaque removal and detecting intimal flaps. In surgical documentation, this procedure is typically noted as a quality assurance measure during complex vascular reconstructions.
Usage
Usage note: Distinguish from postoperative endoscopic procedures.
