Multiple ruptured cerebral aneurysms at the National Hospital of the Kyrgyz Republic between 2008 and 2014: a departmental summary

Despite the rapid progress of vascular neurosurgery with the development of microsurgical and endovascular techniques, the optimal strategy for surgical treatment of multiple cerebral aneurysms has not yet been developed. The indications for choosing one-stage or multi-stage surgery remain unsolved. This is a summary of the departmental routine reports at the Clinic of Neurosurgery, National Hospital of the Kyrgyz Republic. Subjects were 235 patients (124 males and 111 females) with ruptured multiple cerebral aneurysms admitted to the hospital. Their ages ranged from 18 to 72 years (average and standard deviation: 44.3 ± 9.7 years) and 48.1% of patients had 3 or more aneurysms. Among aneurysms that ruptured, 20.4% were a giant aneurysm (>25 mm) and 43.0% of patients had grade IV or V according to the Hunt-Hess Scale. Among 228 patients who were operated on, 147 were treated by single-stage surgery and 81 by multi-stage surgery. Microsurgical operations with clipping of the aneurysm neck were performed in 141 (61.8%) patients (97 single-stage and 44 multi-stage), while 40 (17.5%) patients (16 single-stage and 24 multi-stage) were operated using the endovascular technique. The number of palliative surgeries (trapping, ligation of the internal carotid artery, and reinforcement of the aneurysm wall) was significantly less (p=0.011) with multi-stage surgery (9 out of 81 cases, 11.1%) than with single-stage surgery (38 out of 147 cases, 25.9%). Among 600 aneurysms, 583 (97.2%) were treated by either single-stage surgery (n=296) or multi-stage surgery (n=287). There were no differences in prognosis at discharge between single-stage and multi-stage surgery.
