Value of transcranial Doppler ultrasonography on diagnosing the cerebral vasospasm following subarachnoid hemorrhage / 临床神经病学杂志

Objective To explore the value of transcranial Doppler ultrasonography (TCD) on diagnosing the cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH). Methods TCD was used to detect and monitor the cerebral blood flow status to estimate CVS following SAH in 30 cases, then the results of TCD were analyzed by combining with clinical manifestation and SAH severity on CT. Results 17 patients (56.7%) had the evidence of CVS confirmed by TCD, 10 of them were nonsymptomatic and 7 were symptomatic. The incidences of CVS in patients with Fisher grade Ⅲ and Ⅳ were more higher than gradeⅠandⅡ(P

Correlation between brain natriuretic peptide and cerebral vasospasm following subarachnoid hemorrhage and hyponatremia / 临床神经病学杂志

Objective To explore the correlation between brain natriuretic peptide (BNP) and cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH) and hyponatremia. Methods Plasma BNP levels and serum natrium were assessed at 4 different time periods (1 to 3 days, 4 to 6 days, 7 to 9 days, and 10 to 12 days after SAH) in 30 patients with SAH. Correlation analysis was carried out between plasma BNP and blood sodium level. Plasma BNP levels were compared according to patients with or without CVS, and with or without symptom. The plasma BNP levels of 18 healthy controls were measured meanwhile.Results Plasma BNP levels in SAH patients were significantly elevated compared with control subjects ( P
