Abstract

OBJECTIVE:

To assess outcomes of percutaneous infrainguinal arterial angioplasty for treatment of chronic limb-threatening ischemia (CLI) in poor surgical candidates.

METHODS:

A retrospective clinical analysis of 67 consecutively treated patients (76 limbs) with CLI over a 33-month period was performed. Patients were considered poor surgical candidates because of absent distal target vessels (31 limbs), severe comorbid conditions (36 limbs), or lack of an autologous vein for distal bypass (9 limbs). Limb salvage was defined as preservation of a functional foot without the need for a prosthesis. Technical success was defined as the ability to percutaneously recanalize the arterial segment with less than 30% residual stenosis. Clinical success was healing of ulcers or minor amputation sites, resolving rest pain, or avoiding a major amputation. Successful technical and clinical outcomes were correlated with patient demographics, clinical presentation, and TransAtlantic Inter-Society Consensus arterial lesion characteristics by using the Fisher exact test.

RESULTS:

Seventy-six limbs were treated for rest pain (n = 12), gangrene (n = 22), or nonhealing ulcers (n = 42). There were 40 men and 27 women. The mean age was 70 years (range, 36-94 years). Lesions were located in tibial (n = 55), popliteal (n = 6), and superficial femoral (n = 15) arteries. Arterial recanalization and limb salvage was achieved in 64 (83.5%) limbs. Technical failure (n = 12) correlated with TransAtlantic Inter-Society Consensus D lesions ( P = .009) and the presence of occlusion ( P = .027). Clinical failure (major amputation, n = 12) correlated with the presence of gangrene ( P = .032) or the combination of diabetes, arterial occlusion, and gangrene ( P = .018). The single variables of age, sex, diabetes, and renal failure did not adversely affect outcomes. There was one mortality (myocardial infarction), and there were two major morbidities (femoral artery pseudoaneurysm and sepsis).

CONCLUSIONS:

Peripheral arterial angioplasty should be considered as an alternative to primary amputation in selected patients with CLI who are poor candidates for traditional surgical bypass.
