Abstract Objective: To study the application effects of ultra-high resolution subtraction computed tomography (CT) angiography (CTA) in the follow-up after treatment for intracranial aneurysms.Methods: The clinical data of 98 patients with intracranial aneurysms who were treated in the hospital from June 2020 to January 2022 were retrospectively analyzed. The patients underwent ultra-high resolution subtraction CTA and digital subtraction angiography (DSA) review at 3 months after surgery. Taking DSA as the "gold standard" to analyze the diagnostic value of ultra-high resolution subtraction CTA in diagnosing aneurysm occlusion, residual aneurysm neck, parent artery and intracranial macrovascular patency and presence or absence of postoperative cerebral vasospasm (CVS) and new aneurysm in patients with intracranial aneurysms after treatment. Results: The sensitivity, specificity and accuracy of ultra-high resolution subtraction CTA were 97.87% (92/94), 75.00% (3/4) and 96.94% (95/98) in the diagnosis of aneurysm occlusion in patients with intracranial aneurysms after treatment, were 95.70% (89/91), 85.71% (6/7) and 96.94% (95/98) in diagnosing residual aneurysm neck, were 98.89% (89/90), 62.50% (5/8) and 95.92 (94/98) in diagnosing the parent artery and intracranial macrovascular patency in patients with intracranial aneurysms after treatment, were 62.50% (5/8), 98.89% (89/90) and 95.92% (94/98) in diagnosing the presence or absence of CVS, and were 50.00% (1/2), 98.96% (95/96) and 97.96% (96/98) in the diagnosis of presence or absence of new aneurysm after treatment. Conclusion: Ultra-high resolution subtraction CTA has high diagnostic accuracy in diagnosing tumors and blood vessels in patients with intracranial aneurysms, and it is helpful for postoperative follow-up diagnosis of tumor occlusion and postoperative complications, and can provide a basis for judging clinical follow-up and help clinical formulation of follow-up treatment regimen.
