This paper investigates the efficacy of by computer aided design (CAD)-based three dimensional printing (3DP) individualized guideboard assisted minimally invasive perforation on patients with hypertensive cerebral hemorrhage (HCH).

A total of 108 patients with HCH were enrolled in our department from September 2015 to May 2017, they were randomly divided into two groups, the 48 patients in the invasive group received CAD-based 3DP perforation surgery, the microscopic group of 60 patients received small bone window minimally invasive craniotomy treatment, compared the two groups of patients with postoperative complications and clinical efficacy. On the basis of high-resolution CT data of the invasive group, the three-dimensional images were obtained by computer-aided design and an optimal individualized guideboard was designed, after 3DP technique was used to print, preoperative communicate with the patient and their families the disease and surgical programs by physical model intuitively, and simulate the specific minimally invasive puncture process. Intraoperative individual guides guide the direction and depth of puncture.

The incidence of postoperative complications and clinical efficacy in the invasive group were compared with the microscopic group, the difference was not statistically significant (P>0.05).

Small bone window minimally invasive craniotomy treatment of HCH has been largely accepted by scholars, the invasive group were compared with the microscopic group, treatment effect is no remarkable, which is safe and reliable and worthy of promotion and application, especially the basic-level hospitals that do not meet the conditions of microsurgery treatment.
