[Sub acute ischemia of a lower limb in a patient with juvenile peripheral arterial disease and arterial cocaine toxicity].

A 35-year-old woman was hospitalized for subacute ischemia of the left leg following an intermittent claudication for some weeks. She also presented paleness and coldness of both hands. The radial pulses could not be palpated. Smoking was the only cardiovascular risk factor. Duplex ultrasonography and angiography revealed a left popliteal thrombus combined with low diameter leg arteries and in the upper limbs stenosis of the left radial artery and thrombosis of the right radial artery. Search for a metabolic, embolic or thrombophilic etiology was negative. More minute history taking revealed use of cannabis and recent nasal administration of cocaine. Her condition improved with heparin therapy except for the upper limbs with ischemia of the hands and disabling Raynaud's phenomenon. This report highlights the combined arterial toxicity of drugs often used together by drug addicts. The association of cannabis use and tobacco smoking is not rare in patients with Buerger-like juvenile arteriopathy and cocaine may provoke peripheral vascular disease by embolism or in situ thrombosis. Interrogation of a patient presenting with Buerger-like peripheral arterial disease should insist on detecting use of drugs in association with tobacco smoking.
