Chemical Angioplasty Alone Versus Chemical and Mechanical Angioplasty for Cerebral Vasospasm after Aneurysmal Hemorrhage: A Pilot Randomized Controlled Study

Key Points

• The study aims to compare the effectiveness of chemical angioplasty versus a combination of chemical and mechanical angioplasty in treating cerebral vasospasm after aneurysmal hemorrhage.
• Pilot randomized controlled study design
• Comparison of intra-arterial nimodipine alone versus nimodipine with mechanical angioplasty
• Evaluation of vessel dilation and perfusion improvements
• Assessment of safety profile and retreatments
• Combined angioplasty led to greater vessel dilation than chemical angioplasty alone
• Improved perfusion was observed in the combined treatment group
• Fewer retreatments were necessary in the combined angioplasty group
• The safety profile was deemed acceptable for both methods
