(2018) Civi, Soner; Durdag, Emre; Suner, Halil Ibrahim; Kardes, Ozgur; Tufan, Kadir; 0000-0002-1055-5152; 0000-0003-2854-941X; 0000-0001-6939-5491; 0000-0002-5957-8611; 0000-0003-1509-4575; U-2400-2018; P-5895-2018; AAK-1734-2021; AAJ-5381-2021; AAK-1686-2021
Objective: Percutaneous vertebroplasty (PVP) is one of the frequently preferred interventional methods in spinal surgery. Although it is classified as minimally invasive, the most common complication of this procedure is bone cement leakage. Leakage of bone cement is often asymptomatic, but can lead to serious complications such as paraplegia and pulmonary embolism. In this study, we aimed to investigate the complications and consequences of cement leakage in the percutaneous vertebroplasty procedure. Methods: Between 2009 and 2015, 20 (14 female and 6 male, mean age 69.7) patients who underwent percutaneous vertebroplasty to 26 vertebrae were included in the study. 17 vertebrae were treated for osteoporotic compression (65.3%), 4 vertebrae for pathologic compression fractures (15.3%), 4 vertebrae for traumatic compression fractures (15.3%) and 1 vertebrae for painful hemangioma (3.8%). Leakage localizations of bone cement were classified as venous plexus, paravertebral soft tissue, spinal canal, intervertebral foramen, into the niddle channel and intervertebral disc space. Results: Twelve vertebrae showed no leakage (46.1%). 5 vertebrae had leakage into the niddle channel (19.2%), and 3 had leakage to vertebra disc space leakage (11.5%) and 2 vertebrae had to venous plexus and paravertebral tissue leakage (7.6%) Foraminal and spinal canal leakage (3.8%) was observed in one patient on single level. Radicular pain was seen in one patient. Partial pain control was observed in 20% of the patients while 80% of the patients had complete pain control on follow ups. Conclusion: Major complications following percutaneous vertebroplasty are mostly due to bone cement leaks. In order to prevent major complications, it is necessary to determine the possible causes of leakage. Performing the application with the correct technique with properly prepared bone cement is essential. Also usage of contast dye may be useful for pre-injection risk of leakage complications.

Angiosarcoma is a rare malignancy originating from vascular endothelial cells. Brain metastasis of aniosarcomas are uncommon up to the literature. Penile angiosarcomas are also seldom among all anjiosarcomas. A case with penile angiosarcoma with confirmed brain metastasis is aimed to be reported and contribute to the literature for similar cases.

(2018) Civi, Soner; Tanburoglu, Anil; Suner, Halil Ibrahim; Kardes, Ozgur; Durdag, Emre; Tufan, Kadir; https://orcid.org/0000-0002-1055-5152; https://orcid.org/0000-0001-9627-3502; https://orcid.org/0000-0002-5957-8611; https://orcid.org/0000-0003-2854-941X; https://orcid.org/0000-0001-6939-5491; https://orcid.org/0000-0003-1509-4575; U-2400-2018; AAK-1876-2021; AAJ-5381-2021; P-5895-2018; AAK-1734-2021; AAK-1686-2021
Objective: Carpal Tunnel Syndrome (CTS) is the most frequently encountered entrapment neuropathy. Surgical treatment is usually suggested to patients with severe symptoms. In this study, we aimed to examine the effect of the dominant hand on the clinical results of CTS decompression surgery. Methods: Fifty (5M, 45F) patients were included in the study. The Edinburgh Handedness Inventory was used to identify the dominant hand of patients included in the study. Visual analogue scale (VAS) values were evaluated pre- and postoperatively. Results: Twenty-eight patients underwent surgery on the dominant hand and 22 patients had surgery to their non-dominant hand. The VAS values of patients who underwent non-dominant hand surgery were lower than those who underwent surgery on the dominant hand. Conclusion: In our study, it was determined that patient complacency after surgical procedures performed on dominant hands was less when compared with the non-dominant side. We believe that suitable exercise and protection programs for dominant hands in the postoperative period of carpal tunnel surgery, in addition to a good and careful surgical technique, positively affects the results of surgical treatment.

(2018) Civi, Soner; Bulduk, Erkut Baha; Kocer, Nazim Emrah; Kardes, Ozgur; Suner, Halil Ibrahim; Durdag, Emre; Tufan, Kadir; 0000-0002-5943-9283; 0000-0003-2854-941X; 0000-0002-5957-8611; 0000-0001-6939-5491; 0000-0003-1509-4575; 30569903; AAM-5436-2021; P-5895-2018; AAJ-5381-2021; AAK-1734-2021; AAK-1686-2021
INTRODUCTION AND OBJECT: The aim of our study was to assess the effect of perineural pregabalin administration on the success of coaptation in experimental rat sciatic nerve anastomosis by measuring the expression of anti-inflammatory cytokine TGF-beta. It is thus to provide alternative solutions to this problem which we often see in clinical practice and whose results are not satisfactory. METHODS: In our study, 40 adult, male, Sprague-Dawley rats; 5 groups were randomly assigned Group 1: This group's sciatic nerves were dissected and the surgical site was sutured. Group 2: Rats whose sciatic nerves are sectioned transversely through the fill-thickness and end-to-end anastomosis is performed and no additional procedure is performed. Group 3: Intraperitoneal administration of 30 mg / kg pregabalin for 7 days with anastomosis. Group 4: 30 mg/kg pregabalin given orally for 7 days with anastomosis. Group 5: Given 10 microliters / h pregabalin subcutaneous perineural infusion for 7 days with anastomosis. After 60 days of surgery, the experiment was terminated with high dose thiopental (50 mg/kg). The right sciatic nerves of all animals were taken and sections obtained were examined immunohistopathologically. RESULTS: Inflammation was significantly less in the 5th group than in the other groups. TGF-beta expression in Groups 3, 4, and 5 is significantly higher than Groups 1 and 2, which also supports this situation. Although the expression in group 5 was not statistically significant, the number of TGF-beta expression was higher than Groups 3 and 4. In terms of immunohistochemical properties; 1 to 3, 1 to 4, 1 to 5, 2 to 5 groups were statistically significant (p<0,05). CONCLUSIONS: In conclusion, perinural infusion of pregabalin into the anastomotic region has not been previously tried in the literature and it has been found that immunohistochemistry provides positive contributions to healing of anastomosis. More research is needed to demonstrate that this effect is superior to other methods of administration of the drug.

Objective: Stereotaxic biopsy is an important surgical procedure that provides definite diagnosis in brain lesions. It is possible to obtain diagnosis with minimal invasive manner in deeply located and critical localized lesions. There are large case series in the literature. We aimed to present our experience of magnetic resonance (MR) guided 310 stereotaxic biopsies in this study. Method:We retrospectively evaluated age and gender distribution, locations of the lesions, histopathologic results, and complications of 310 cases which MR guided stereotactic biopsied was performed in our clinic between 2012 and 2018. In addition, technical information was also provided. Results:Stereotactic frame application was performed with local anesthesia and surgical procedure was performed by under general anesthesia. Of 310 patients 169 were male (55%) and were 141 female (45%). Mean age was 57.28 (3-87). 184 of the lesions were hemispheric (59%), and the most common diagnosis was glioblastoma multiforme (34.19%). 8 patients were not diagnosed (2%). Complications developed in 13 cases (4%) and 2 of cases were died in the early phase due to the procedure (0.6%). Histopathological diagnostic success was 99% Conclusion:The results of our study show that the stereotactic biopsy procedure applied in the MRI guideline is reliable and feasible with low complication rate and high effectiveness in cases where definitive histopathologic results are required for treatment planning.

(2022) Hasbay, Bermal; Kayaselcuk, Fazilet; Suner, Halil Ibrahim; Sarialioglu, Faik; https://orcid.org/0000-0002-5957-8611; 000832603900001; AAJ-5381-2021
AIM: To reevaluate the medulloblastoma cases according to histomorphological and molecular features, and to investigate the relationship between the prognostic factors of the new WHO classification by applying Beta-catenin, YAP1, GAP1, p53, and INI1 antibodies immunohistochemically. MATERIAL and METHODS: This study includes 41 patients who have been diagnosed with medulloblastoma between 2007-2019 in pathology department. Immunohistochemically, p53, beta-catenin, YAP1, GAP1, and INI1 immune markers were applied, and the relationship between the results and the prognostic parameters was evaluated statistically. RESULTS: When 41 patients were classified into WHO medulloblastoma histological subtype groups according to histomorphological features, 22 (53.7%) patients were classified as classical type, 11 (26.8%) patients as desmoplastic nodular type, and 8 (19.5%) patients as large cell/anaplastic type medulloblastoma. According to their molecular characteristics, 14 (34.1%) patients were in the Non-WNT/SHH group, 5 (12.2%) patients were SHH mutant, 17 (41.5%) patients were SHH wild, and 5 (12.2%) patients were in the WNT active group. There was no statistically significant correlation between age, gender, tumor size, recurrence, Ki67 proliferation index with molecular types and histopathological types. CONCLUSION: In our study, metastasis at the time of diagnosis, histological large cell anaplastic type, immunohistochemical p53 positivity, molecular SHH mutant type were the statistically significant indicators of worse prognosis and shorter survival time.

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; 28944945
AIM: 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.
