Dissectors for pulmonary thromboendarterectomy

Ann Thorac Surg. 1991 May;51(5):842-3. doi: 10.1016/0003-4975(91)90150-o.


Even with circulatory arrest during pulmonary thromboendarterectomy, continued back-bleeding obscures the operative field. This necessitates frequent interruptions of dissection to allow aspiration with a second instrument. Therefore, pulmonary thromboendarterectomy dissectors are described that allow simultaneous suction of blood from the operative field. Before the use of these dissectors, circulatory arrest time was 59 +/- 23 minutes in 124 consecutive patients. In the last 10 consecutive patients using these dissectors, the mean circulatory arrest time has been 52 +/- 22 minutes (p = not significant). It is anticipated that with a larger database, the ability to aspirate blood simultaneously during the dissecting process will result in a significant shortening of circulatory arrest time.
