Fluoroscopically assisted thromboembolectomy: an improved method for treating acute arterial occlusions

Area of Science:

• Vascular Surgery
• Interventional Radiology

Background:

• Acute arterial and graft occlusions pose significant clinical challenges.
• Traditional thromboembolectomy can cause arterial damage and requires substantial contrast agents.

Purpose of the Study:

• To evaluate the safety and efficacy of fluoroscopically assisted thromboembolectomy for acute arterial or graft occlusions.
• To assess the technique's ability to identify and facilitate treatment of underlying arterial lesions.

Main Methods:

• Bilateral femoral artery dissections were performed in a canine model to assess balloon overdistention.
• Fluoroscopically assisted thromboembolectomy was used to treat 21 patients with acute occlusions over 25 months.
• Underlying arterial lesions were identified and treated with repeat thrombectomy, angioplasty, or stenting.

Main Results:

• Balloon overdistention was 23% in the iliac artery and 40% in the femoral artery in the canine model.
• In 21 patients, fluoroscopically assisted thromboembolectomy successfully restored luminal continuity.
• Fifteen residual lesions were identified and treated, with 10 patients requiring additional vascular reconstruction.

Conclusions:

• Fluoroscopically assisted thromboembolectomy is a safe and effective method for treating acute arterial occlusions.
• The technique minimizes arterial damage and contrast agent usage.
• It aids in accurate identification and treatment of underlying arterial lesions, potentially reducing the need for further interventions.
