[Acute finger ischemia: A retrospective study of 13 patients]. / Ischémie digitale aiguë : étude rétrospective de 13 cas.

ABSTRACT

BACKGROUND: Acute ischemia of the upper limbs is rare in comparison with ischemia of the lower limbs. The origins of this condition are varied. GOALS We retrospectively analyzed cases of acute finger ischemia (Raynaud's phenomena was excluded) in a dermatology department between 2008 and 2013 in order to evaluate the etiology and management of this phenomenon. RESULTS: Thirteen cases of finger ischemia were reported. The mean age was 54 years. Active smoking was noted in 11 cases. Ischemia was acute in 9 cases and subacute in 4 cases. The location was unilateral in 10 cases and bilateral in 2. Etiologies were dysplasia of the palmar arch, antiphospholipid antibody syndrome, frostbite, distal arteritis linked to smoking, paraneoplastic arteritis, Buerger's disease, polyarteritis nodosa, stenosis of the subclavian artery, and 3 cases of embolic origin (ulnar, cardiac, and paraneoplastic aneurysm). In the acute phase, antiplatelets were given in 6 cases, anticoagulants in 10 cases and ilomedin in 6 cases. Sympathectomy was performed in 1 case and amputation in 2 cases. DISCUSSION: This study illustrates the diversity of etiologies of finger ischemia. The etiological test battery should be broad and include immunological and thrombophilia tests, arterial and cardiac investigations, cervical radiography and CT scan (screening for cancer). Close collaboration between dermatologists, hematologists, vascular surgeons and radiologists is essential for the management of these patients.
