Reversed intracranial blood flow in patients with an intra-aortic balloon pump.

abstract：:Background and Purpose- Intracranial thrombi can be characterized according to their permeability as measured by contrast agent penetration. Thrombus composition and its associated pathogenesis are important factors affecting treatment and secondary prevention. We aimed to explore the histopathologic factors explainin...
