Operative arteriography: an indicator for infrainguinal bypass
The Japanese Journal of Surgery
|November 1, 1983
Summary
Preoperative angiography often fails to fully visualize arteries for infrainguinal bypass surgery. Intraoperative arteriography improves visualization, aiding surgical decisions for complex cases.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Complete arteriographic delineation of recipient arteries is not always feasible before infrainguinal artery bypass surgery.
- Preoperative angiography failed to provide distinct visualization in 13 out of 63 patients with infrainguinal artery occlusion.
Purpose of the Study:
- To evaluate the utility of intraoperative arteriography in improving visualization of recipient arteries and distal circulation for infrainguinal bypass surgery.
- To determine if prebypass operative arteriography can serve as an indicator for arterial bypass surgery.
Main Methods:
- Retrospective analysis of 63 patients undergoing infrainguinal artery bypass surgery.
- Comparison of preoperative angiography with intraoperative arteriography findings.
- Assessment of bypass surgery performed on vessels visualized or not visualized on preoperative angiography.
Main Results:
- Preoperative angiography was insufficient in 13 patients.
- Intraoperative arteriography successfully visualized target vessels in 8 of these 13 patients.
- Bypass surgery was performed on previously unvisualized vessels in 5 patients and on vessels with poorly defined distal circulation in 3 patients.
Conclusions:
- Intraoperative arteriography significantly enhances visualization of recipient arteries and distal circulation.
- Prebypass operative arteriography is a valuable tool and may serve as an additional indicator for arterial bypass surgery.
