Background: Adverse outcomes after aneurysm clipping can be potentially reversible, when managed appropriately. Methods: This is a case report describing kinking of a perforator due to clipping of parent vessel aneurysm. Results: Complete recovery of a high-grade motor deficit was achieved after instant reintervention with application of smaller clips in combination with gelfoam soaked in papaverine. Conclusion: Use of evoked potentials and intraoperative digital subtraction angiography are recommended and may help in preclinical diagnosis. Knowledge of delayed perforator kinking as a complication may lead to a more rapid diagnosis and management.
