The Efficacy of Percutaneous Transluminal Angioplasty on the Limb Salvage and Recovery of Symptoms in Patients With Buerger's Disease With Critical Limb Ischemia.

INTRODUCTION: Buerger's disease, or thromboangiitis obliterans, is associated with limb-threatening chronic arterial lesions. In this study, we sought to investigate the efficacy of the percutaneous transluminal angioplasty method for the treatment of critical limb ischemia (CLI) in patients with Buerger's disease in our modest cohort.

METHODS: Patients diagnosed with CLI secondary to Buerger's disease who underwent percutaneous transluminal angioplasty between May 2014 and June 2017 were retrospectively investigated. Patient demographics, presentations, procedural details, responses to percutaneous treatment, complications, limb salvage, wound healing, reinterventions, and early follow-up data were recorded.

RESULTS: The cohort included 24 patients with Buerger's disease presenting with CLI observed in 46 limbs. Presentations were gangrene in 12 patients, ulcer formation in 7 patients, and rest pain in the remaining 5 patients. All patients received percutaneous balloon angioplasty, with limb salvage in 21 patients (87.5%). Revascularization was achieved in 87.5% of the destination arteries at the primary intervention and overall technical success rate including reinterventions reached 95.8%. Following the procedures, a total of 22 patients had clinical response with at least ≥1 Rutherford category and mean Rutherford category significantly improved from 5.2 ± 0.74 to 1.6 ± 0.7 (P<.001). Limb salvage rate was 87.5%. Complete wound healing was achieved in all patients with ischemic ulcers at 3.9 ± 2.6 months (range 1-13 months) post revascularization. Mean follow-up duration was 16.07 ± 3.4 months and 6 patients (who were especially subjected to cigarette smoke) required reinterventions.

CONCLUSION: Percutaneous treatment of arterial occlusions in patients with Buerger's disease seems feasible in the current era of improving devices and angioplasty materials. Procedures may be safely performed with good technical and clinical success rates, and without mortality or complications as experience increases.
