Abstract：
UNASSIGNED: Intravenous thrombolysis (IVT) for acute brain infarctions caused by aortic dissection (AD) may lead to fatal outcomes; thus, it should be ruled out, especially if hypofibrinogenemia occurs after IVT. Successful management of AD-related acute brain infarction with hypofibrinogenemia after IVT has not been reported previously.
UNASSIGNED: An 84-year-old woman developed sudden left limb weakness and aphasia for almost 4 h. Alteplase was administered intravenously immediately after cerebral hemorrhage was ruled out by emergent head computed tomography (CT). An anomaly suspected to be AD was detected during subsequent routine chest CT, which was confirmed by CT angiography to be a thoracoabdominal aortic dissecting aneurysm (DeBakey type I). Severe hypofibrinogenemia was also noted. After effective blood pressure control, intramuscular injection of vitamin K, and rehydration therapy, her brain cell metabolism improved, hemiplegia improved slightly, and hypofibrinogenemia recovered gradually. The patient\'s cerebral hemorrhage did not progress, there was no chest pain or no aggravation of hemiplegia, and the fibrinogen level gradually returned to normal. The condition was stable during hospitalization. At 1.5 months after discharge, the patient showed minimal change in condition.
UNASSIGNED: The symptoms of AD may be nonspecific and latent. IVT may be allowed to perform for some patients with AD related ischemical stroke, And IVT can improve the neural symptoms of AD-related ischemic stroke, but close monitoring is needed to avoid aneurysm rupture. Fibrinogen levels should also be monitored periodically after IVT for early detection of hypofibrinogenemia.
