Insights
Cardiac myxoma rarely causes abdominal aortic occlusion above the renal arteries. This case highlights a rare presentation of paraplegia due to aortic blockage by a cardiac myxoma, leading to severe ischemia.
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Neurology
Background:
- Cardiac myxomas, typically benign tumors, can present with diverse symptoms, including embolic events.
- Abdominal aortic obstruction by cardiac myxoma is uncommon, with lesions above the renal arteries being exceedingly rare.
- Acute paraplegia is an unusual manifestation of cardiac myxoma.
Abstract:
The presentations of cardiac myxoma are diverse, from asymptomatic to a variety of symptoms due to embolization. Occlusion of abdominal aortic bifurcation by straddled myxoma is not common; however, obstructive level above renal artery is very rare. We present a patient with cardiac myxoma who presented with acute onset of paraplegia. The aorta was occluded from the level of the liver dome to the renal arteries, and catastrophic outcome (ischemia/reperfusion) following its removal.
