Catheter-based management of a catheterization related stroke

Ischemic stroke is a rare and serious complication of coronary angiography and percutaneous coronary intervention, which has high morbidity and mortality. To our knowledge, there is no large-scale randomized controlled trial for the management of catheter-related ischemic stroke. In this case study, we presented a 46-year-old male with peri-procedural ischemic stroke during the coronary angiography (CAG). The CAG was terminated after the stroke and the left carotid artery was selectively cannulated, and digital subtraction angiography (DSA) revealed total occlusion (Modified Thrombolysis in Cerebral Infarction, mTICI, 0) of the M1 part of the left middle cerebral artery (MCA). A stent-assisted thrombectomy was performed and the DSA revealed restoration of flow to the left MCA with mTICI 3 flow in the distal branches. The next day, the neurological exam showed no sensory, motor deficits. The patient was discharged four days later. In the setting of catheter-related stroke, mechanical thrombectomy seems to be the least time-consuming and effective approach.
