Objective: Decompressive craniectomy (DC) is one of the commonly used treatment modalities for refractory intracranial hypertension after traumatic brain injury. The objective of this study is to assess the functional outcome following DC in closed traumatic brain injury based on Glasgow Outcome Scale (GOS). Materials and Methods: This is a retrospective study conducted at Nepal Mediciti Hospital, Nepal, from September 2017 to October 2019. Data of the patients who had undergone DC for closed traumatic brain injury were reviewed from medical record files. Patients who had DC for nontraumatic causes were excluded from the study. Functional outcome was assessed using GOS at 3 months of follow-up. Results: Of the 52 decompressive craniectomies, 46 were included in the study. The majority was male (71.7%). The mean age and the mean Glasgow Coma Scale (GCS) score at presentation were 41.87 (standard deviation [SD] ± 15.29) and 7.59 (SD ± 2.97), respectively. The most common mode of injury was road traffic accident (76.1%). 60.9% had GCS score ≤8 while 39.1% had >8 GCS on admission. 34.8% had both the pupils reactive while 58.7% were anisocoric. Majority had Marshall IV and above grade of injury (67.4%). Sixteen (34.8%) had inhospital mortality. Favorable outcome was seen in 39.1%. GCS score >8 at presentation (72.2%, P < 0.001), bilaterally intact pupillary reflexes (75%, P < 0.001), Marshall grade injury ≤3 on computed tomography scan (90%, P < 0.001), and age <50 years (50%, P = 0.039) were significantly associated with favorable outcome. Procedure-related complications were seen in 36.9%. Conclusion: Favorable outcome was seen in 39.1%. Age <50 years, higher GCS score at presentation (>8), intact pupillary reflexes, and lower Marshall grade injuries were associated with favorable outcome. We recommend a larger prospective study to assess the long-term functional outcome after DC using extended GOS.
Objective: The purpose of this study is to assess demographic, clinical, and morphological characteristics of patients with brain arteriovenous malformations (bAVMs). The relation of outcome using modified Ranklin Scale (mRS) at time of discharge, early and last follow ups with respect to various factors. Materials and Methods: Demographic data, arteriovenous malformation characteristics, and treatment outcomes were evaluated in 43 bAVMs treated with microsurgery between 2009 and 2019. For this series, 43 patients were retrospectively reviewed. A subgroup analysis for Spetzler-Martin grades (SMG) I/II, III, IV/V and III–V were performed. The mRS was used to assess functional outcomes. Results: Overall, mean age at diagnosis was 33 years (standard deviation = 19). Transient deficit, mRS deterioration and impaired functional outcome occurred less frequently in SMG I–II patients compared with Grade III–V patients combined (29% vs. 32% respectively, P = 0.00). All patients with SMG Grade I, Supplemented SMG Grade 2, 3, 4 and 6 had a mRS score of 2 or less at the last follow-up. Age was the only significant predictor of overall outcome after bAVM surgery on Chi-square test ( P = 0.046), i.e: all patients <20 years had mRS score of 2 or less on last follow-up. Unfavorable outcome (mRS score of 3 or more than 3) level increased with higher grades in SMG on long term follow-up. Conclusion: The results of our case series of bAVM with SMG Grade I and Suplemented Grade 2, 3, 4 and even higher grade i.e., 6 can have excellent overall outcome after microsurgical resection. Association of factors which increases the grading system of bAVM like eloquence, deep venous drainage and increasing sizes did not correlate with the predicted unfavorable outcomes, whereas age of patients was a predictor of overall outcome. Although the small sample size of this study is a limitation, age of patient plays important role on the overall outcome.
Introduction: Lumbar degenerative spondylolisthesis is an acquired slippage of a vertebra due to degenerative arthritis of the facet joints without any defect in the vertebral ring. Degenerative spondylolisthesis is commonly treated with posterior decompression and posterolateral fusion. This study aims to evaluate the clinical outcome of posterior decompression and instrumented posterolateral fusion surgery by analysing patient reported outcome measures. Materials and Methods: A retrospective study in which patients who had posterior decompression and instrumented posterolateral fusion for lumbar degenerative spondylolisthesis between September 2017 and August 2019 at Nepal Mediciti Hospital were included in the study. Other types of spondylolisthesis managed with similar technique and patients who had follow up period of less than three months were excluded. Functional outcome was assessed by comparing pre and post-operative patient reported outcome measures: VAS leg pain, VAS back pain and Oswestry Disability Index (ODI). The paired t-test was used for statistical analysis. Results: Of the 16 patients, 81.25% were female. Mean age and mean follow up period were 58.81± 10.47 years and 13.56±7.15 months respectively. Seventy five percent had grade I spondylolisthesis. Most common level of spondylolisthesis was L4/5 (62.5%). Fourteen patients reported improvement in their symptoms after surgery. The changes in functional outcome scores between baseline and at follow up evaluation were as follows: 32.70 ± 17.44 points for ODI, 3 ±1.89 for VAS leg pain, and 5.37 ± 2.36 for VAS back pain (P<0.001). Superficial wound infection was the most common complication observed in 18.3%. Conclusion: In our case series, 87.5% had improvement in their symptoms after surgery. The change in mean score of patients’ reported outcome measures before and after surgery was statistically significant. We recommend a prospective comparative study between decompression alone and the fusion technique for the evaluation of long term functional outcome.
Objective: This studies aims to evaluate the outcome of Microvascular Decompression (MVD) using a muscle graft for interposition in Trigeminal Neuralgia (TN), Hemifacial Spasm (HFS) and Glossopharyngeal Neuralgia (GPN). All surgeries were performed by a single surgeon (G.R.S). Methods: In total, 26 patients with TN, HFS and GPN underwent MVD from September 2007 to April 2019. All the patients were either medically refractory or poor symptom tolerance. The mean follow-up period was 72 months. Results: Each MVD was performed using an autologous muscle graft with interposition of vessels. One patient (3.84%) had reoccurrence after MVD with muscle graft and two patients (7.69%) had partial relief. Conclusion: Various types of prosthesis are used for transposition and interposition of vessels in MVD surgeries. Although in our case series we didn't use any prosthesis for the comparative outcome, the use of muscle graft showed minimal reoccurrence rate with benefit of being cost effective. Therefore, we need randomized controlled trials to prove the superiority of muscle graft from other prosthesis material.
