Successful Limb Salvage in a Newly Diagnosed Diabetic Patient With Critical Limb Ischemia Managed With Percutaneous Transluminal Angioplasty and Stenting

Diabetic foot ulcers are a major cause of morbidity and limb loss, particularly when complicated by underlying vascular insufficiency. We report the case of a middle-aged male patient who presented with generalized weakness, epigastric discomfort, fever, and a chronic non-healing ulcer over the right foot. Initial evaluation revealed newly diagnosed type 2 diabetes mellitus, acute kidney injury secondary to dehydration, and a chronic diabetic foot ulcer. Despite stabilization with medical management, the ulcer failed to heal, prompting further vascular evaluation. Peripheral angiography demonstrated peripheral arterial occlusive disease (PAOD) with critical limb ischemia (CLI) involving the right lower limb. The patient subsequently underwent percutaneous transluminal angioplasty with stenting of the right superficial femoral artery, resulting in restoration of limb perfusion. Following revascularization, the ulcer showed progressive healing with significant clinical improvement. At follow-up, the patient had regained full functional mobility and resumed normal occupational activities. This case underscores the importance of early recognition of vascular insufficiency in diabetic foot ulcers and highlights the role of timely endovascular intervention in achieving limb salvage.
