Summary
Intraoperative angioscopy offers valuable visualization of peripheral vascular anatomy during surgery. This technique aids in identifying graft issues and can alter surgical decisions, improving patient outcomes.
Area of Science:
- Vascular Surgery
- Medical Imaging
- Endovascular Techniques
Background:
- Peripheral vascular anatomy assessment is crucial for surgical success.
- Traditional methods like angiography have limitations in real-time visualization.
Purpose of the Study:
- To describe the technique of intraoperative angioscopy for peripheral vascular anatomy.
- To evaluate the utility and impact of angioscopy on intraoperative management.
Main Methods:
- Utilized angioscopes (0.85-2.9 mm) in 86 peripheral vascular procedures.
- Performed angioscopic inspections on arteries, anastomoses, and vein grafts.
- Documented findings and changes in surgical management.
Main Results:
- Obtained useful images in 85% of procedures (73/86).
- Angioscopy led to changes in management, including anastomotic revision (14%) and in situ venous valve revision (47%).
- Identified potential causes of graft occlusion in 30% of cases.
Conclusions:
- Intraoperative angioscopy provides direct visual assessment of luminal patency and anastomotic integrity.
- This technique alters intraoperative procedures and offers insights not achievable with angiography.
- Complications were minimal, with one requiring revision and minor flaps noted.
