What are the medical complications associated with aneurysmal subarachnoid hemorrhage (aSAH)?
The medical complications associated with aneurysmal subarachnoid hemorrhage (aSAH) include hyperglycemia, brain energy metabolic crisis, anemia, heparin-induced thrombocytopenia, and deep venous thrombosis. Hyperglycemia can increase the risk of poor outcome in aSAH patients, while anemia can compromise brain oxygen delivery. Transfusion of red blood cells can result in a significant rise in cerebral oxygen delivery and a reduction in oxygen extraction ratio, and higher hemoglobin values are associated with improved outcomes. Heparin-induced thrombocytopenia is likely to occur in around 5% of aSAH patients and can increase the risk of thrombotic complications, vasospasm/DCI, and death. Deep venous thrombosis is another medical complication associated with aSAH.
