“…CT Angiography and Digital Subtracted Angiography were used as investigative tool to diagnose aneurysm. 11,12 Nevertheless absurdity and imprudent counsel from the referring physicians who may have falsely labeled grade I SAH as simple headache has also been recited in our overview. 10 Besides, as high as 81% of our patients as evidenced by CTA presented with ruptured aneurysms, because of lack of awareness among the community from the concerned authority to formulate a screening setup among the vulnerable.…”

Introduction: Aneurysmal Subarachnoid Hemorrhage(SAH) is a neurosurgical emergency for which testing for COVID PCR was not an option and was unlikely to change the management of the case. Hence, all surgeries were performed without COVID PCR and Rapid Diagnostic Test (RDT) at our center for the welfare of the patient despite risks involved for the surgeons and supporting staff. Methods: Data were collected retrospectively of all cerebral aneurysm patients who received treatment at Annapurna Neurological Institute and Allied Sciences during the covid pandemic between February 2020 to May 2021. Their demographic profile, clinical and imaging characteristics, treatment decision, postoperative complication, postoperative functional status in terms of Modified Rankin Scale were taken into consideration and analyzed. Result: 63 patients were enrolled in study with patient age ranging from 9 years to 81 years. Male to female ratio was 1:3. Amongst them, 28% had hypertension. 82% underwent microsurgical clipping while three patients underwent coiling. Basilar Top aneurysm, Para clinoid aneurysm, PICA aneurysm underwent simple coiling. Wrapping, bypass and trapping were performed in 1,1, and 3 cases respectively. At the time of discharge, most of the patients (77%) achieved good functional recovery (mRS ≤ 2) while mortality was reported in 8% of patients. Based on our experience and limited dataset, posterior location of aneurysm, increasing HuntHess Grade and modified fisher grade had poor prognosis, related with degree of cerebral vasospasm, and delayed cerebral ischemia. Conclusion: Results from our study showed outcomes in surgical patients with aneurysmal SAH at par with international standards. COVID pandemic although posed initial difficulties, with proper guidelines and protocols in place, we were able to perform the emergency surgeries without compromising our standards.

Digital subtraction angiography (DSA) has been a fluoroscopic golden investigative tool to know the vascular angiography of the brain and spinal cord. The technique in performing this procedure exposes residents in accessing the major vessels, branches of the arch of aorta, selective angiography and diagnosing different vascular anomalies of brain and spine. They are also exposed to the knowledge of different diagnostic catheters, its manipulation, use of dye and radiation exposure and safety. We would like to share our experience in training and disseminating the knowledge of digital subtraction angiography to the residents.
