[Coronary ischemia caused by pseudoxanthoma elasticum and myocardial revascularization with double arterial graft]. / Isquemia coronaria producida por seudoxantoma elástico y revascularización miocárdica con doble injerto arterial.

We present a case of an 18 year-old woman with pseudoxanthoma elasticum, who had a biopsy taken from a lesion. Although she was asymptomatic, we tried to rule out myocardial ischemia with a treadmill and cardiac gammagraphy with Talio. The isotopic studies and the ergometry were positive and the patient underwent coronariography. This study showed a severe triple-vessel disease. We did an angiography of the supraaortic arteries, mamarian artery, and mesenteric artery. These studies showed no obstructive lesions. The treatment of patient was a double by-pass with internal mammary artery and one by-pass with safena vein grafts with satisfactory results.
