Single-Center Analysis of Reliability of 3D-DSA Dual Volume Reconstruction for Evaluation of Endovascularly Treated Intracranial Aneurysms.

Abstract

To explore the applications of 3-dimensional digital subtraction angiography (3D-DSA) double-volume reconstruction technique (DVRT) in endovascular embolization for the treatment of intracranial aneurysm. A cohort of 112 patients with a total of 127 intracranial aneurysms admitted to the neurosurgery department from June 2018 to October 2019 were selected. Cerebrovascular angiographies were performed after admission. Patients were divided into observation group (56 of 112) and control group (56 of 112) randomly when endovascular embolization was performed. Individuals in the control group were treated with 2D-DSA technique, and patients in the observation group were treated with 3D-DSA DVRT. The Raymond method was used to determine the degree of embolism. There was no significant difference in sex, blood pressure, cerebral atherosclerosis, aneurysm site or size, contrast agent dosage, x-ray dose, or surgical cost between the 2 groups. There was no postoperative recurrence in the observation group. However, the recurrence rate in the control group is 10.7% (6 of 56). Postoperative thrombosis occurred in 1 case (1 of 56, 1.8%) in the observation group and 7 cases (7 of 56, 12.5%) in the control group. No postoperative cerebral infarction was recorded in the observation group, while 5 cases (8.9%, 5 of 56) in the control group presented with postoperative cerebral infarction. 3D-DVRT for intracranial aneurysm embolization provides the best working angle, clearly shows the process of aneurysm embolization and its relationship with peripheral vessels, and reduces the occurrence of surgical complications including postoperative recurrence, thrombosis, and cerebral infarction.
