[Two patients treated with intra-aortic balloon pump counterpulsation after subarachnoid hemorrhage]

Intra-aortic balloon pump counterpulsation (IABP) was used to treat two patients with symptomatic vasospasm after subarachnoid hemorrhage. One could not tolerate triple H therapy (hypertensive hypervolemic hemodilution) because of poor cardiac function and another suffered acute myocardial infarction after aneurysm surgery followed by cardiac failure. IABP increased cerebral blood flow and prevented cerebral infarction in the former case but this could not reverse cerebral ischemia in the latter. IABP may be one choice for patients with vasospasm after subarachnoid hemorrhage.
