Objective To investigate treatment efficacy and the factors influencing prognosis of conservative treatment of hypertensive intracerebral hemorrhage in basal ganglia. Methods A retrospective analysis was conducted on the clinical data of 174 patients with hypertensive intracerebral hemorrhage in basal ganglia who were admitted to our hospital during the period from April 2005 to December 2014. All the patients were given internal medicine conservative treatment and followed up to observe the clinical curative effect to analyze the prognosis. Results Of the 174 patients, 50 patients died and 4 patients were persistent vegetative state. 124 patients were followed up for 2-117 months and they were classified according to ability of daily life(ADL) prognosis scale: 43 cases were in I grade, 53 cases in II grade, 21 cases in III grade, 3 cases in IV grade, 4 cases in V grade. 96 cases achieved favourable outcomes and 28 cases got poor outcomes.The results of Chi square test revealed that GCS scale and intracerebral hemorrhage volume were the factors influencing prognostic of hypertensive intracerebral hemorrhage in basal ganglia. Conclusion There were many prognosis factors related with hypertensive intracerebral hemorrhage. The curative effect and prognosis in patients with conservative treatment is obvious in these patients with high GCS scale and less intracerebral hemorrhage volume.
