abstract：:Local intra-arterial fibrinolysis (LIF) is considered to support spontaneous recanalisation, which does not usually occur fast enough to prevent an infarct. Therefore, LIF may, at least theoretically, be especially useful in occlusions with large thromboembolic masses. We report our experience of LIF with urokinase in...

If the vessel wall can be regenerated at the neck orifice of an aneurysm, thereby reducing the blood flow into the aneurysm, the recurrence ...
