AbstractIntraoperative angioscopy was performed in three patients who underwent pulmonary embolectomy for massive pulmonary embolism. Angioscopy followed conventional techniques such as extracting the clot by a gallstone forceps, using a Fogarty catheter in the pulmonary tree or squeezing of the lungs. The rationale for angioscopy was to assess the result of these usual "blind" techniques. In two patients residual thrombus was detected and removed under direct visual control. Our initial experience suggests that intraoperative angioscopy appears to be useful in the detection of residual thrombus material, especially in the asanguinous, arrested heart. The small size of the angioscope allows easily access to the secondary, and up to the tertiary pulmonary branches. Clots can be visualized and extracted under direct visual control.
