Study of Venous Thromboembolism Risk Profiles and Prophylaxis in Neurosurgical Inpatients

Study Overview
=================
Brief Summary
-----------------
Venous thromboembolism (VTE), comprising deep venous thrombosis (DVT), pulmonary embolism (PE), or both, is a life-threatening complication in postoperative patients. VTE has been estimated an incidence ranged from 79 per 100000 to 269 per 100000 population1. The incidence of VTE rises up to 3.0% in average among all postoperative neurosurgical patients in recent studies, but the number varies in a large range according to primary diseases. This cross-sectional study was aimed to investigate the incidence, associated risk factors, prophylaxis, treatment, and outcomes of VTE in a large clinical neurosurgery center in China.

Detailed Description
-----------------
Venous thromboembolism (VTE), comprising deep venous thrombosis (DVT), pulmonary embolism (PE), or both, is a life-threatening complication in postoperative patients. This cross-sectional study was aimed to investigate the incidence, associated risk factors, prophylaxis, treatment, and outcomes of VTE in a large clinical neurosurgery center in China. 9010 patients underwent neurosurgery procedure were included. Distribution of age, sex, whether received PICC during perioperative period, and some special primary diseases are significantly different between VTE and non-VTE patients. Student's test and chi-square test were performed for analyses. We investigated VTE incidence, risk factors, prophylaxes, treatment and outcomes in postoperative neurosurgical patients, and summarized the VTE susceptible population of the patients, providing a VTE patient profile for neurosurgeons to concern.
