Evaluation of small hypothalamic hamartomas with 3D constructive interference in steady state (CISS) sequence.

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...
