Thromboangiitis obliterans: Aggressive angioplasty provides a potential solution (randomized pilot study)

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Peripheral Artery Disease Research

Background:

• Thromboangiitis obliterans (Buerger's disease) is an inflammatory vascular condition affecting small and medium-sized arteries, often leading to critical limb ischemia.
• Conventional treatments like vasodilators and antiplatelet agents have shown limited efficacy in managing Buerger's disease.
• The need for more effective therapeutic strategies for Buerger's disease is critical due to its potential for severe limb complications.

Purpose of the Study:

• To evaluate the efficacy and safety of balloon angioplasty as an endovascular intervention for patients diagnosed with Buerger's disease.
• To compare the outcomes of endovascular therapy with standard medical management (cilostazol and aspirin) in patients with Buerger's disease.
• To assess the impact of balloon angioplasty on key clinical and hemodynamic parameters, including ulcer healing, ankle-brachial index (ABI), and transcutaneous oximetry (TcPO2).

Main Methods:

• A randomized controlled study involving 82 patients with Buerger's disease between January 2006 and December 2016.
• 52 patients underwent aggressive endovascular intervention (balloon angioplasty), while 30 patients received medical treatment (cilostazol and aspirin) as a control group.
• Outcomes were assessed over 30 months, focusing on ulcer healing duration, ABI, peak systolic velocity, and TcPO2 levels, with allocation concealment ensuring unbiased randomization.

Main Results:

• Endovascular intervention demonstrated a statistically significant improvement in ulcer healing duration (3 months vs. 5.8 months, p < 0.001) and TcPO2 levels (27.23 to 71.32 mmHg, p < 0.01).
• The ankle-brachial index significantly improved from 0.54 to 0.82 (p < 0.01) in the endovascular group post-procedure.
• Angiographic success rates were high (100% for supragenicular, 90% for infrapopliteal lesions), with no major procedural complications reported.

Conclusions:

• Endovascular therapy, specifically balloon angioplasty, is an effective and safe minimally invasive treatment for Buerger's disease.
• Modified endovascular techniques yield promising results, offering significant improvements in limb perfusion and healing.
• Balloon angioplasty should be considered a valuable therapeutic option for patients suffering from Buerger's disease.
