Successful Endovascular Therapy for Total Occlusion of the Distal Radial and Ulnar Artery with Palmar Artery Lesion in a Patient with Critical Hand Ischemia Associated with Systemic Sclerosis.

Vasculopathy of systemic sclerosis (SSc) is known to lead to severe limb ischemia and is often associated with macrovascular diseases. Revascularization of proximal macrovascular lesions that cause limb ischemia in patients with SSc has been recommended; however, it has rarely been reported for lesions below-the-elbow (BTE) involving the palmar artery. A 66-year-old female patient with SSc experienced critical hand ischemia (CHI) with gangrene of the left third finger that failed to respond to conventional pharmacological treatment. Angiography revealed total occlusion of the distal radial and ulnar arteries with a palmar artery lesion. Balloon angioplasty was performed for bilateral occlusive lesions around the wrist, which improved antegrade flow to the digital artery. Endovascular therapy may be a feasible option for BTE lesions involving palmar artery disease, presenting with CHI in SSc, when conventional conservative treatments fail.
