Surgical outcomes of delayed clipping in ruptured intracranial aneurysms of anterior circulation: Experience from a low-middle-income country

Objective: To evaluate the surgical outcomes of delayed microsurgical clipping for ruptured intracranial aneurysms (RICAs) of anterior circulation. Methods: This retrospective, cross-sectional study assessed the surgical outcomes of 50 patients who underwent surgical clipping for "ruptured aneurysms" with subarachnoid haemorrhage after the 21st post-bleed day, from May 01, 2022, till May 01, 2023, at the Department of Neurosurgery, Punjab Institute of Neurosciences, Lahore, Pakistan. Results: The mean age of patients was 49.66 +/- 6.231 years with a female preponderance of 54%. Out of 50 cases, 21 were midline aneurysms (42%), followed by left-sided laterality in 16 cases (32%). Aneurysm of the anterior communicating artery was the most common accounting for 42% of the patients. Forty-nine patients returned home after first postoperative week without deficits, with a success rate of 98%. Seizures, surgical site infection and cerebrospinal fluid leak were noted in 6%, 4% and 2% patients, respectively. Conclusion: Delayed clipping in RICAs after the 21st post-bleed day is advocated, especially in resource-constrained settings. Meticulous surgical technique and asepsis are responsible for great postoperative outcomes.
