Abstract
Many reports focus on the probability of intracranial hemorrhage as a complication after recombinant tissue plasminogen activator (rt-PA) therapy. However, thromboembolic complications are not well discussed. We experienced a case in which severe thromboembolic complications occurred in the right radial and right ulnar artery. Arterial fibrillation was observed in this case. If multiple thrombi exist in the atrium or ventricle, multiple small embolic particles may appear following thrombolytic therapy, and that may be a potential risk of secondary thromboembolic complications due to incomplete dissolution of thrombi. Transesophageal echocardiography is a standard method to detect intracardiac sources of emboli in the case of arterial fibrillation. Transesophageal echocardiography is, however, an invasive method for patients with ischemic stroke during rt-PA therapy. High resolution enhanced CT could be a useful tool and may be a reliable alternative to transthoracic echocardiography. Careful assessment of thromboembolic complications following rt-PA therapy in patients with arterial fibrillation is needed. In this case report and mini review, we would like to discuss about the accurate diagnostic methods to detect cardiac or undetermined embolic sources and provide expedited stroke care. These embolic sources may be more readily discovered during rt-PA therapy within the limited therapeutic time window.
