Who is Likely to Present in Poor Neurologic Condition After Aneurysmal Subarachnoid Hemorrhage? Risk Factors and Implications for Treatment

AbstractIntroductionAneurysmal subarachnoid hemorrhage is a type of spontaneous hemorrhagic stroke, which is caused by a ruptured cerebral aneurysm. Cerebral vasospasm (CVS) is the most grievous complication of subarachnoid hemorrhage (SAH). The aim of this study was to examine the risk factors that influence the onset of CVS that develops after endovascular coil embolization of a ruptured aneurysm.Materials and methodsThe study was designed as a cross-sectional study. The patients included in the study were 18 or more years of age, admitted within a period of 24 h of symptom onset, diagnosed and treated at a university medical center in Serbia during a 5-year period.ResultsOur study showed that the maximum recorded international normalized ratio (INR) values in patients who were not receiving anticoagulant therapy and the maximum recorded white blood cells (WBCs) were strongly associated with cerebrovascular spasm, increasing its chances 4.4 and 8.4 times with an increase of each integer of the INR value and 1,000 WBCs, respectively.ConclusionsSAH after the rupture of cerebral aneurysms creates an endocranial inflammatory state whose intensity is probably directly related to the occurrence of vasospasm and its adverse consequences.

OBJECTIVETakotsubo cardiomyopathy (TC) in patients with aneurysmal subarachnoid hemorrhage (aSAH) is associated with high morbidity and mortality. Previous studies have shown that female patients presenting with a poor clinical grade are at the greatest risk for developing TC. Intra-aortic balloon pumps (IABPs) are known to support cardiac function in severe cases of TC, and they may aid in the treatment of vasospasm in these patients. In this study, the authors investigated risk factors for developing TC in the setting of aSAH and outcomes among patients requiring IABPs.METHODSThe authors retrospectively reviewed the records of 1096 patients who had presented to their institution with aSAH. Four hundred five of these patients were originally enrolled in the Barrow Ruptured Aneurysm Trial, and an additional 691 patients from a subsequent prospectively maintained aSAH database were analyzed. Medical records were reviewed for the presence of TC according to the modified Mayo Clinic criteria. Outcomes were determined at the last follow-up, with a poor outcome defined as a modified Rankin Scale (mRS) score > 2.RESULTSTC was identified in 26 patients with aSAH. Stepwise multivariate logistic regression analysis identified female sex (OR 8.2, p = 0.005), Hunt and Hess grade > III (OR 7.6, p < 0.001), aneurysm size > 7 mm (OR 3, p = 0.011), and clinical vasospasm (OR 2.9, p = 0.037) as risk factors for developing TC in the setting of aSAH. TC patients, even with IABP placement, had higher rates of poor outcomes (77% vs 47% with an mRS score > 2, p = 0.004) and mortality at the last follow-up (27% vs 11%, p = 0.018) than the non-TC patients. However, aggressive intra-arterial endovascular treatment for vasospasm was associated with good outcomes in the TC patients versus nonaggressive treatment (100% with mRS ≤ 2 at last follow-up vs 53% with mRS > 2, p = 0.040).CONCLUSIONSTC after aSAH tends to occur in female patients with large aneurysms, poor clinical grades, and clinical vasospasm. These patients have significantly higher rates of poor neurological outcomes, even with the placement of an IABP. However, aggressive intra-arterial endovascular therapy in select patients with vasospasm may improve outcome.
