Intermediate surgical outcome in patients suffering poor-grade aneurysmal subarachnoid hemorrhage. A single center experience.

BACKGROUND: It is known that patients suffering poor-grade aneurysmal subarachnoid hemorrhage (aSAH) have a dismal prognosis. The importance of early intervention is well established in the pertinent literature. Our aim was to assess the functional outcome and overall survival of these patients undergoing surgical clipping. MATERIAL AND METHODS: In the current retrospective study we included all consecutive poor-grade patients after spontaneous SAH who presented at our institution over an eight-year period. All participants suffering SAH underwent brain CT angiography (CTA) to identify the source of hemorrhage. We assessed the severity of hemorrhage according to the Fisher grade classification scale. All patients were surgically treated. The functional outcome was evaluated six months after the onset with the Glasgow Outcome Scale. Finally, we performed logistic and Cox regression analyses to identify potential prognostic risk factors. RESULTS: Our study included twenty-three patients with a mean age of 53 years. Five (22%) patients presented with Hunt and Hess grade IV, and eighteen (78%) with grade V. The mean follow-up was 15.8 months, while the overall mortality rate was 48%. The six-month functional outcome was favorable in 6 (26%) patients. The vast majority of our patients died between the 15th and the 60th post-ictal days. We did not identify any statistically significant prognostic factors related to the patient's outcome and/or survival. CONCLUSIONS: Poor-grade aSAH patients may have a favorable outcome with proper surgical management. Large-scale studies are necessary for accurately outlining the prognosis of this entity, and identifying parameters that could be predictive of outcome.

Extreme lateral lumbar interbody fusion (XLIF) in the management of degenerative scoliosis: a retrospective case series.

BACKGROUND: Surgical treatment of adult degenerative scoliosis (DS) always remains a challenge and often necessitates complex multilevel surgery via traditional open approaches. However, the severity of the procedure, in association with the fact that many of these patients are at an advanced age with several comorbidities, results in high rate of complications. Therefore, during the last decade, minimally invasive procedures have gained a place in the treatment of this pathology. Our aim is to determine the safety and efficacy of extra lateral lumbar interbody fusion (XLIF) with or without supplemented instrumentation in the treatment of DS. METHODS: In a retrospective case series study, we reviewed the files of patients who underwent XLIF in our Hospital between 2008 and 2017. We recorded the patients' demographic characteristics, clinical parameters such as back-pain [visual analogue scale (VAS)] and back-related disability [Oswestry Disability Index (ODI)], as well as radiological parameters including the Cobb angle. Comparison of the before and after results were performed with the t-test and Chi-square test, where appropriate. RESULTS: Twelve patients fulfilled the eligibility criteria of our study. All patients were female, with a mean age of 64.5 years (SD =7.8 years) and 28 months (SD =13 months) follow-up. The XLIF decreased the pain intensity by 4.66 cm (SD =1.23 cm), and improved the back-related disability by 26% (SD =8.35%) in the ODI scale at the 6-month follow-up. Similarly, scoliosis improved by an average of 11.5° (SD =7°) and lordosis changed by an average of 13.5° (SD =10.86°). All changes were statistically significant. There were three complications, two patients presented meralgia paresthetica, which resolved spontaneously in 3 months, and in one patient occurred an intraoperative bowel perforation treated with bowel anastomosis. CONCLUSIONS: XLIF is a feasible and efficient alternative in the treatment of DS. It can be the treatment of choice in elderly patients in whom comorbidities increase the perioperative risk of complications.

The value of the identification of predisposing factors for post-traumatic amnesia in management of mild traumatic brain injury.

OBJECT: To identify the risk factors for post-traumatic amnesia (PTA) and to document the incidence of PTA after mild traumatic brain injuries. METHODS: This was a prospective study, affecting mild TBI (mTBI) (Glasgow Coma Scale 14-15) cases attending to the Emergency Department between January 2009 and April 2012 (40 months duration). Patients were divided into two groups (Group A: without PTA, and Group B: with PTA, and they were assessed according to the risk factors. RESULTS: A total of 1762 patients (males: 1002, 56.8%) were meeting study inclusion criteria [Group A: n = 1678 (83.8%), Group B: n = 84 (4.2%)]. Age, CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs, and skull base fractures), anticoagulation therapy and seizures were independent factors of PTA. There was no statistically significant correlation between PTA and sex, convexity fractures, stroke event, mechanism of mTBI (fall +/or beating), hypertension, coronary heart disease, chronic smokers and diabetes (p > 0.005). CONCLUSION: CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs and skull base fractures), age, seizures and anticoagulation/antiplatelet therapy, were independent factors of PTA and could be used as predictive factors after mTBI.
