Item Effect of decompressive hemicraniectomy in patients with acute middle cerebral artery infarction 2050(2021) Suner, Halil İbrahim; Tanburoglu, Anil; Durdag, Emre; Civi, Soner; Gunesli Yetisken, Aylin; Kardes, Ozgur; Andic, Cagatay; Tufan, Kadir; 0000-0002-5957-8611; 0000-0003-2854-941X; 0000-0001-9627-3502; 0000-0001-8581-8685; 33890450; AAJ-5381-2021; P-5895-2018; AAK-1876-2021; AAM-1671-2021Background/aim: We aimed to determine in which cases this procedure may be more effective based on the data of patients who underwent decompressive hemicraniectomy (DHC). Material and methods: Overall, 47 patients who underwent DHC due to acute middle cerebral artery (MCA) infarction between January 2014 and january 2019 were retrospectively investigated. These patients were divided into two groups: those who died after DHC (Group A) and those who survived DHC (Group B). The groups were compared in terms of various parameters. We investigated whether the patient's modified Rankin scale (mRS) status changed depending on age (> 60 and < 60 years). Results: The median age of all patients was 65 (37-80) years; groups A and B had median ages of 66.5 (37-80) and 61 (44-79) years (p = 0.111), respectively; 55.3% patients were male. The elapsed times until hospitalization after the onset of symptoms were 4.5 and 3 h in groups A and B, respectively (p = 0.014). The median GCS score at the time of admission was 7 (5-12) and 10 (8-14) in groups A and B, respectively (p = 0.0001). At the time of admission, 63.3% patients in group A had anisocoria, whereas no patient in group B had anisocoria (p = 0.0001). In postoperative period, 40% patients in group A and all patients in group B received AC/AA treatment. The survival of patients aged < 60 and > 60 years who underwent DHC for MCA infraction was 61.5% and 26.5%, respectively (p = 0,041). The median mRS of patients < 60 and > 60 years were 4 (1-6) and 6 (1-6), respectively (p = 0.018). Conclusion: Age, DHC timing, and elapsed time until hospitalization or access to treatment directly affect the functional outcome and survival in MCA-infarcted patients who underwent DHC. In patients in whom the medical treatment fails, early DHC administration will increase survival without waiting for neurological worsening once herniation is detected radiologically.Item Lumbosacral discitis as a rare complication of laparoscopic sacrocolpopexy(2020) Durdag, Gulsen Dogan; Alemdaroglu, Songul; Durdag, Emre; Simsek, Seda Yuksel; Turunc, Tuba; Yetkinel, Selcuk; Baran, Safak Yilmaz; Celik, Husnu; 0000-0001-6939-5491; 0000-0002-2165-9168; 0000-0002-5064-5267; 0000-0003-4335-6659; 32500164; AAK-1734-2021; AAL-1530-2021; AAI-9594-2021; AAK-7016-2021; AAI-8400-2021; ABF-6439-2020Introduction and hypothesis Sacrocolpopexy is considered to be the gold-standard procedure for apical compartment prolapse. However, complications such as sacral hemorrhage, small bowel obstruction, port site herniation, mesh erosion, mesh exposure, and occasionally discitis may occur. The aim of this study is to show laparoscopic treatment of L5-S1 discitis 3 months following laparoscopic sacrocolpopexy. Methods Two surgical interventions of a case with narrated video footage is presented. Results Laparoscopic sacrocolpopexy following hysterectomy in the first part and re-laparoscopy because of a diagnosis of discitis refractory to medical treatment, and removal of mesh along with anterior L5-S1 discectomy for curative debridement in the second part is demonstrated. Conclusion Frequency of postoperative discitis has been increased by the widespread use of a laparoscopic approach. In order to reduce the complication rate, surgical technique allowing the needle to penetrate only the depth of the anterior longitudinal ligament and usage of monofilament suture for mesh attachment is recommended. In treatment, removal of the sacral mesh, and even extensive tissue debridement, may be necessary.Item Usefulness of End-to-Side Bridging Anastomosis of Sural Nerve to Tibial Nerve : An Experimental Research(2017) Civi, Soner; Durdag, Emre; Aytar, Murat Hamit; Kardes, Ozgur; Kaymaz, Figen; Aykol, Sukru; 0000-0003-2854-941X; 0000-0001-6939-5491; 0000-0002-1055-5152; 28689390; P-5895-2018; AAK-1734-2021; U-2400-2018Objective : Repair of sensorial nerve defect is an important issue on peripheric nerve surgery. The aim of the present study was to determine the effects of sensory-motor nerve bridging on the denervated dermatomal area, in rats with sensory nerve defects, using a neural cell adhesion molecule (NCAM). Methods : We compared the efficacy of end-to-side (ETS) coaptation of the tibial nerve for sural nerve defect repair, in 32 Sprague-Dawley rats. Rats were assigned to 1 of 4 groups : group A was the sham operated group, group B rats had sural nerves sectioned and buried in neighboring muscles, group C experienced nerve sectioning and end-to-end (ETE) anastomosis, and group D had sural nerves sectioned and ETS anastomosis was performed using atibial nerve bridge. Neurological evaluation included the skin pinch test and histological evaluation was performed by assessing NCAM expression in nerve terminals. Results : Rats in the denervated group yielded negative results for the skin pinch tests, while animals in the surgical intervention groups (group C and D) demonstrated positive results. As predicted, there were no positively stained skin specimens in the denervated group (group B); however, the surgery groups demonstrated significant staining. NCAM expression was also significantly higher in the surgery groups. However, the mean NCAM values were not significantly different between group C and group D. Conclusion : Previous research indicates that ETE nerve repair is the gold standard for peripheral nerve defect repair. However, ETS repair is an effective alternative method in cases of sensorial nerve defect when ETE repair is not possible.Item Safety and Efficacy of Ventriculostomy Procedures under Dual Antiplatelet Therapy in Patients Treated with Stent Assisted Coiling in Subarachnoid Hemorrhage(2018) Kardes, Ozgur; Civi, Soner; Suner, Halil Ibrahim; Durdag, Emre; Tufan, Kadir; Andic, Cagatay; Ozmete, Ozlem; 28944945AIM: Stent assisted coiling (SAC) is an alternative in the treatment of ruptured aneurysms. Stenting requires the use of dual antiplatelet agents. Hydrocephalus is a complication of subarachnoid hemorrhage (SAH) and may require ventriculostomy. Antiplatelet treatment carries a risk of hemorrhage in ventriculostomy. The anti-aggregant effect starts at least four hours after the initial doses of treatment. However, in many studies, ventriculostomy was performed before antiplatelet treatment and hemorrhagic complications were related to the procedure. The aim of this study was to determine the risk of ventriculostomy related hemorrhage in patients with impaired thrombocyte function and to contribute to the literature. MATERIAL and METHODS: Between 2011 and 2016, 53 patients treated with SAC due to SAH in our clinic were retrospectively evaluated. Hemorrhagic complication risks due to antiplatelet therapy related to ventriculostomy were also evaluated. RESULTS: All of the ventricular catheter procedures were performed at least 1 day after the dual therapy (in average 4.3 days after SAC). In 5 patients 1 ventriculostomy was performed, in 2 patients 2, and in 1 patient 6 ventriculostomies were performed. Although radiological hemorrhage was present on the catheter tract in 4 patients, no temporary or permanent neurological deficit was observed. CONCLUSION: Impaired thrombocyte functions pose a risk in ventriculostomy. Also, evaluating the risk of hemorrhage before the antiplatelet treatment reaches its full effect may lead to false results. Studies with small patient groups with anti-aggregant therapy and impaired thrombocyte functions also contribute to the literature. Larger studies regarding this subject are needed.Item Effect of gabapentin on primary surgical treatment of experimental sciatic nerve injury in rats(2018) Kardes, Ozgur; Civi, Soner; Bulduk, Erkut Baha; Selcuk, Fazilet Kaya; Suner, Halil İbrahim; Durdag, Emre; Tufan, Kadir; 30394505BACKGROUND: The aim of our study is to minimize the morbidity related to nerve injury by determining the protective effects of gabapentin in experimental sciatic nerve injury and end-to-end anastomosis model in rats and to guide clinical studies on this subject. METHOD: In our study, 40 adult male Sprague-Dawley rats were randomly divided into the following five groups: I: Only surgical intervention was applied; II: The sciatic nerve was cut properly and was repaired by end-to-end anastomosis. No additional procedure was performed; III: A single dose of gabapentin at 30 mg/kg was given after anastomosis; IV: 30 mg/kg gabapentin was given for 3 days after anastomosis; and V: 30 mg/kg gabapentin was given for 7 days after anastomosis. The experiment was terminated with high-dose thiopental (50 mg/kg) 60 days after the surgical intervention. The right sciatic nerve was taken from all animals. The obtained sections were examined immunohistopathologically. RESULT: Immunohistochemical properties and Schwann cell proliferation were found to be statistically significantly lower in the control group than in the other groups. Schwann cell proliferation was higher in Group 3 than in Group 5. Immunohistochemical changes were significantly lower in Group 4 than in Group 3. Axonal degeneration was also higher in Group 4 than in Group 3. CONCLUSION: Gabapentin promotes neurological recovery histopathologically in peripheral nerve injury due to its neuroprotective properties. Our study results show that gabapentin can be used as an adjunctive therapy to primary surgical treatment after peripheral nerve injury.
