Routine intraoperative angiography. An essential adjunct in vascular surgery

Area of Science:

• Vascular Surgery
• Diagnostic Imaging

Background:

• Arterial reconstructive procedures are critical for restoring blood flow.
• Early graft failure remains a significant complication in vascular surgery.
• Intraoperative assessment is essential for optimizing surgical outcomes.

Purpose of the Study:

• To evaluate the utility of intraoperative angiography in identifying correctable defects during arterial reconstructive procedures.
• To determine the impact of intraoperative angiography on preventing early graft failures.

Main Methods:

• Intraoperative angiography was performed in 155 arterial reconstructive procedures.
• Procedures included bypass, endarterectomy, embolectomy, thrombectomy, primary reconstruction, and angioplasty.
• Identified defects were categorized and corrected.

Main Results:

• Defects were identified in 27 cases (17%) and subsequently corrected.
• Commonly identified defects included technical errors, thrombus, debris, and unrecognized runoff lesions.
• The highest likelihood of identifying lesions was observed in bypass surgery, particularly with distal leg anastomoses.

Conclusions:

• Intraoperative angiography is a valuable adjunct to vascular surgery.
• Routine use can identify and correct defects, thereby obviating many early graft failures.
• This technique is particularly beneficial for bypass surgery involving leg arteries.
