Angioscopy as an adjunct to arterial reconstructive surgery: a preliminary report

Area of Science:

• Vascular Surgery
• Medical Imaging
• Interventional Cardiology

Background:

• Arterial occlusive diseases pose significant challenges in vascular surgery.
• Traditional diagnostic methods may have limitations in visualizing complex arterial pathologies.
• Minimally invasive techniques are crucial for improving surgical outcomes.

Purpose of the Study:

• To evaluate the utility of angioscopy as an adjunct in various vascular interventions.
• To assess angioscopy's effectiveness in diagnosing arterial occlusive conditions.
• To determine angioscopy's role in guiding procedures like in situ vein grafting and laser recanalization.

Main Methods:

• Utilized three different angioscopes (1.7 mm, 2.8 mm, 3.2 mm) in 14 patients undergoing vascular procedures.
• Introduced scopes via arteriotomy with continuous saline infusion for a clear field of view.
• Performed 24 angioscopic evaluations across procedures including arterial embolectomy, femoropopliteal bypass, and laser recanalization.

Main Results:

• Achieved adequate visualization with all angioscope types.
• Identified atherosclerotic occlusion, intimal flaps, and thrombus in various arterial segments and grafts.
• Confirmed successful valvulotomy in saphenous veins for in situ grafting.
• Demonstrated direct visualization for laser fiber positioning and post-recanalization inspection.

Conclusions:

• Angioscopy is a potentially valuable diagnostic tool for arterial occlusive disease.
• It serves as an effective adjunct for in situ saphenous vein grafting and laser arterial recanalization.
• Direct visualization improves procedural accuracy and confirmation of successful outcomes.
