RESUMO
Cerebral vasospasm is common in aneurysmal subarachnoid hemorrhage (aSAH). It often occurs several days after aSAH, and then peaks at 1 week, causing local cerebral ischemia, cerebral infarction and neurological deficit dysfunction. Cerebral vasospasm is an important reason for death or disability after aneurysm rupture. Cerebral angiography is the gold standard for the diagnosis of cerebral vasospasm, but now transcranial Doppler ultrasound, CT cerebral perfusion imaging, near infrared spectroscopy and other non-invasive inspection methods are increasingly popular and easy to carry out extensively. Treatments of cerebral vasospasm include hemodynamics and drug therapy, with early removal of hematoma, diastolic blood vessels, and enhanced brain perfusion as the main research direction. Joint treatments are the future trends of cerebral vasospasm therapy. In this review, we summarized the diagnosis and treatment of cerebral vasospasm after aneurysmal subarachnoid hemorrhage.
RESUMO
Objective To investigate the curative effects of hematoma evacuation (HE) combined with external ventricular drainage (EVD) and simple EVD in the treatment of patients with intraventricular hemorrhage secondary to hypertensive intracerebral hemorrhage (HICH). Methods We retrospectively analyzed the clinical data of 70 patients who were diagnosed with HICH from Jun. 2012 to Jun. 2015 in Changzheng Hospital of Second Military Medical University. The patients were divided into EVD combined with HE group (EVD+HE group, n=31) and EVD group (n=39) according to the different choices of operation. The Glasgow Coma Scale (GCS) score, length of neurointensive intensive care units (NICU) stays, in-hospital mortality, incidences of lung infection, intracranial infection and rebleeding, and modified Rankin Scale (mRS) scores and Glasgow Outcome Scale (GOS) scores after 6 months were compared between two groups. Then we screened the patients with supratentorial hematoma volume greater than 30 mL in the EVD+HE group (n=20) and EVD group (n=13), and compared the above clinical indicators between two groups. Results The in-hospital mortality rate of patients in the EVD+HE group was significantly higher than that in the EVD group (29.0% vs 5.1%, P=0.008). The survival patients were included in the subsequent research, including 22 cases in the EVD+HE group and 37 in the EVD group. The improved GCS (ΔGCS) scores of survival patients in the EVD+HE group was significantly higher than that in the EVD group (3.9±3.5 vs 1.2±3.3, P0.05). After screening, the patients with supratentorial hematoma volume greater than 30 mL in the EVD+HE group had significantly higher improved GCS (ΔGCS) scores (3.8±4.0 vs 1.1±2.4, P=0.044), lower 6-month mRS scores (4.2±1.6 vs 5.3±0.7, P=0.025) and higher 6-month GOS scores (3.1±2.0 vs 1.7±0.7, P=0.030) than those in the EVD group. The length of NICU stays, incidences of rebleeding, lung infection and intracranial infection of patients were not significantly different between the EVD+HE and EVD groups (P>0.05). Conclusion For patients with supratentorial hematoma volume greater than 30 mL, HE combined with EVD is superior to simple EVD in treating intraventricular hemorrhage secondary to hypertensive intracranial hemorrhage.
