When the aortoiliac bifucation is occluded:Leriche syndrome

Intoduction

Leriche syndrome is a special type of obliterating arterial disease of the lower limbs which results in thrombotic occlusion of the aortoiliac junction.

Case report

We report the case of a 65-year-old patient with known cardiovascular and nephrological pathological history, who presented with acute abdominal pain with intermittent claudication of the lower limbs and in whom clinical examination found abolition of the femoral pulses.

Discussion

Doppler ultrasound of the abdominal aorta revealed aortic thrombosis in the lower of the renal segment extended to the iliac bifurcation with damping of upstream circulatory speeds. We supplemented with a CT angiography of the aorta and lower limbs which demonstrated extensive arterial thrombosis from the abdominal aorta to the bilateral external iliac arteries.

•

Leriche syndrome is a special type of obliterating arterial disease of the lower limbs.

•

It's Responsible of a unique triad of symptoms, including claudication, impotence, and decreased peripheral pulses.

•

The diagnosis is suspected clinically, objectified by Doppler ultrasound and detailed by CT angiography.

•

CT angiography is the examination of choice in the diagnosis of Leriche syndrome.

[Acute venous mesenteric ischemia in a young COVID-19 positive subject: a case report]

L'ischémie mésentérique aiguë (IMA) résulte d'une diminution ou d'une interruption brutale du flux sanguin mésentérique ayant pour conséquence un apport sanguin inadéquat au tractus gastro-intestinal, responsable de lésions ischémiques et inflammatoires évoluant souvent vers une nécrose en l'absence de traitement adapté, l´insuffisance vasculaire peut résulter d'une embolie ou d'une thrombose artérielle ou d'une thrombose veineuse. Nous présentons un cas rare d´ischémie veineuse mésentérique chez un homme de 33 ans dû au coronavirus (COVID-19) chez qui le diagnostic était fait grâce à l´échographie et surtout à la tomodensitométrie (TDM).
