Isolated splenic infarction following left cardiac catheterization: case report and a review of the literature

Athero-embolic isolated splenic infarction following left cardiac catheterization

Instrumentation of the aorta during cardiac catheterization, resulting in peripheral embolization, is an underdiagnosed clinical entity. Such an atheromatous embolization can present in a subtle way or could be catastrophic. Isolated splenic infarction as a complication of the procedure is extreme rare. We report a 59-year-old man with risk factors for atherosclerotic vascular disease who underwent percutaneous coronary intervention and presented 3 days later with isolated splenic infarction. He was managed conservatively with heparin. Further evaluation revealed a concomitant mural thrombus in an abdominal aortic aneurysm, which could be a contributing factor along with atheroembolization from advanced atherosclerosis. Our case highlights the importance of using a right brachial or radial approach in an individual with significant atherosclerotic vascular disease and with an abdominal aortic aneurysm.
