Thromboembolic cerebral ischaemic attack complicating cardiac catheterization. Successful local thrombolytic therapy with reduced dose rt-PA.
ABSTRACT Cerebral ischaemia caused by thromboembolism is a possible complication of diagnostic and interventional cardiac catheterization. In this case report we describe the diagnostic steps and successful treatment strategy in the management of a patient who suffered from cerebral ischaemia during cardiac catheterization. Initial CT scanning to exclude cerebral haemorrhage was followed by angiography through the cardiac catheterization sheath in the right femoral artery. Occlusion just before the intracranial bifurcation of the right internal carotid artery was found and local thrombolysis given with a reduced dose of 34 mg rt-PA. The subsequent angiogram showed restored perfusion in the affected vessel after completion of thrombolytic therapy and resolution of neurological symptoms.
