Postoperative assessment of arterial reconstructive surgery using Doppler flow detection
- 14 Downloads
The ankle systolic pressure was measured by the Doppler flow detector during the postoperative course after arterial reconstructive surgery in 61 limbs. The ankle systolic pressure was expressed as a pressure index (PI). There were 2 patterns in the recovery of PI after successful reconstructions. In one of these patterns, PI returned to the normal level within 24 hours. The other group represented a delayed recovery of PI. A comparative study between these 2 groups indicated that the delay in the recovery of PI may be chiefly related to a poor distal run-off. There was no relationship between the recovery pattern of PI and the late patency of reconstructed arteries. On the other hand, follow-up examination by means of the ankle pressure measurement was useful to detect new occurrences of stenotic lesions in the postoperative period.
