“…These results are consistent with other studies that show an improvement in diagnosis using stereoscopic 3D displays [13,25]. Liu showed that the accuracy of detection of cerebral aneurysms was the same (100%) for stereoscopy and conventional CT workstation display for aneurysms over 3 mm; however, it improved with aneurysms less than 3 mm (94% for stereoscopy and 82% for conventional workstation) [25]. Harake et al found that clinicians preferred viewing 3D echocardiography images of both simple and complex lesions in stereoscopic display, as evidenced by more time and interaction spent viewing stereoscopic display when both displays were equally available for viewing [13].…”

“…There was an improvement in accuracy and confidence of diagnosis of pulmonary vein stenosis with fewer type 2 errors for the more complex diagnostic cases with multiple lesions.

The use of three-dimensional (3D) technologies in medical practice is increasing; however, its use is largely untested. One 3D technology, stereoscopic volume-rendered 3D display, can improve depth perception. Pulmonary vein stenosis (PVS) is a rare cardiovascular pathology, often diagnosed by computed tomography (CT), where volume rendering may be useful. Depth cues may be lost when volume rendered CT is displayed on regular screens instead of 3D displays. The objective of this study was to determine whether the 3D stereoscopic display of volume-rendered CT improved perception compared to standard monoscopic display, as measured by PVS diagnosis. CT angiograms (CTAs) from 18 pediatric patients aged 3 weeks to 2 years were volume rendered and displayed with and without stereoscopic display. Patients had 0 to 4 pulmonary vein stenoses. Participants viewed the CTAs in 2 groups with half on monoscopic and half on stereoscopic display and the converse a minimum of 2 weeks later, and their diagnoses were recorded. A total of 24 study participants, comprised of experienced staff cardiologists, cardiovascular surgeons and radiologists, and their trainees viewed the CTAs and assessed the presence and location of PVS. Cases were classified as simple (2 or fewer lesions) or complex (3 or more lesions). Overall, there were fewer type 2 errors in diagnosis for stereoscopic display than standard display, an insignificant difference (p = 0.095). There was a significant decrease in type 2 errors for complex multiple lesion cases (≥3) vs simpler cases (p = 0.027) and improvement in localization of pulmonary veins (p = 0.011). Subjectively, 70% of participants stated that stereoscopy was helpful in the identification of PVS. The stereoscopic display did not result in significantly decreased errors in PVS diagnosis but was helpful for more complex cases.

“…[ 44 ] Three-dimensional rotational angiography can clearly show the anatomical characteristics of MCA and its branches that is helpful for the formulation of treatment plan. [ 45 ] The application of stents can reduce the recurrence rate of aneurysms by changing the hemodynamics of the brain and endothelialization of the stents. In addition, stents have less influence on the parent artery and its branches.…”

Background: The purpose of this study is to compare the prognosis and effective rate of interventional embolization and surgical clipping in the treatment of middle cerebral artery aneurysms, to provide evidence-based basis for the selection of clinical treatment. Methods: By searching PubMed, Cochrane library, Medline, Embase and other databases, we collected the related studies interventional embolization and surgical clipping in the treatment of middle cerebral artery aneurysms, whether it was a randomized controlled trial or not. According to the relevant inclusion and exclusion criteria, 2 researchers independently screened and extracted the relevant data. Quality of life, residual neck and recurrence rate, incidence of ischemic cerebral infarction, intracranial infection rate, incidence of vasospasm and rebleeding rate were measured. Revman5.4 software was used for Meta-analysis. Results: There were 3658 patients included in 30 literatures, including 1478 patients treated with interventional embolization and 2180 patients treated with surgical clipping. The rate of low quality of life (odds ratio [OR] = 1.68, 95% confidence interval [CI]: 1.36–2.07, P < .00001) and intracranial infection rate (OR = 8.79,95% CI: 4.47–17.27, P < .00001) in the interventional embolization group were lower than those in the surgical clipping group. The postoperative rebleeding rate (OR = 0.46, 95% CI: 0.29–0.73, P = .0009), residual neck and recurrence rate (OR = 0.32, 95% CI: 0.24–0.43, P < .00001) in the interventional embolization group were higher than those in the surgical clipping group. The heterogeneity of residual neck and recurrence rate were high, so subgroup analysis was performed. We divide them into short-term group (OR = 0.68, 95% CI: 0.40–1.13, P = .13) and long-term group (OR = 0.23, 95% CI: 0.16–0.33, P < .00001). The results showed that the residual neck and recurrence rate in the interventional embolization group were higher than those in the surgical clipping group. There was no significant difference in the incidence of cerebral vasospasm (OR = 1.09, 95% CI: 0.64–1.86, P = .74) and ischemic stroke (OR = 0.87, 95% CI: 0.63–1.19, P = .37) between the 2 treatments. Conclusion: According to the current clinical research evidence, compared with interventional embolization in the treatment of middle cerebral artery aneurysms, the quality of life of patients after clipping is lower, the incidence of intracranial infection is higher, but the residual neck, and recurrence rate are reduced. The risk of rebleeding is also reduced. There was no significant difference in the incidence of vasospasm and ischemic stroke between the 2 groups.

“…For this reason, considerable research effort has gone into developing methods and systems that are capable of fusing multimodal imaging data and presenting the surgically relevant information in interactive 3D displays. 25 In the field of surgical practice, greater improvement in programs and virtual immersion has been applied, an example of this is the Immersive Touch Aneurysm Clipping Simulator (ITACS) which provide realistic haptic virtual reality clipping of a patient-based cerebral aneurysm. The system provides force feedback simultaneously in real time.…”

Background The neurosurgical approach to clipping cerebral aneurysms has been a complex challenge for all neurosurgeon experts in cerebrovascular surgery. The three-dimensional computed tomography angiography (3D-CTA) allows identifying bone and vascular structures close to an aneurysm to simulate in virtual 3D images, the appropriate and safest approach to cerebral aneurysm clipping. Objectives This study aims to share our experience using 3D simulation as a support to the safe planning for cerebrovascular disease surgery. Materials and Methods We reviewed the surgical outcomes from a cerebrovascular neurosurgeon using the 3D-CTA images in 360-degree reconstruction in the planning of the preoperative surgical procedure for the treatment of brain aneurysm. In all patients, the virtual surgical approach was replicated in real-time surgery. Results We analyzed 34 patients around 51 ± 8 years of age. Of these, 76.5% (n = 26) and 23.5% (n = 8) were males and females, respectively. Saccular aneurysms were the most frequent (85%), the Arteries affected by aneurysms were middle cerebral artery (n = 6), basilar tip (n = 6), vertebral artery in V3 and V4 (n = 6), and posterior cerebral artery (n = 5). The virtual surgical pterional approach was the most frequently used (50%), followed by fronto-orbito-zigomático (29%) and far lateral (15%) approaches. There were no intraoperative complications in any patient. Conclusion Preoperative 3D virtual reality simulation is a great support tool to perform a safe surgical procedure in real-time for the treatment of simple and complex brain aneurysms.
