    Bilateral high-level percutaneous cervical cordotomy in cancer pain due to lung cancer: A case report
    (Elsevier Science, 2006-07-11) Bekar, Ahmet; Kocaeli, Hasan; Abaş, Faruk; Bozkurt, Merlin; Uludağ Üniversitesi/Tıp Fakültesi/Beyin ve Sinir Cerrahisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; 6603677218; 6603500567; 8546184300; 16202046200
    Background: Computed tomography–guided high-level percutaneous cordotomy has been used unilaterally or bilaterally for the treatment of localized intractable pain in malignancies. Case Description: A 57-year-old man was admitted to the hospital with the complaint of intractable pain involving the left side of the chest, axillary region, and shoulder. He was operated for small cell lung cancer on the left side in December 2003 and received radiotherapy and chemotherapy. His neurological examination was normal. Magnetic resonance imaging of the thorax revealed contrast- enhancing lesions on the left side extending to mediastinum and pleura. His pain was relieved completely after the first cordotomy procedure, and he was discharged from the hospital on the second postoperative day. The patient was readmitted to the hospital with the complaint of severe unilateral chest pain like the initial pain on the right side 4 days after cordotomy. The CT-guided bilateral high-level percutaneous cordotomy was performed with a 15-day interval. Conclusion: The CT-guided bilateral high-level percutaneous cordotomy can be used in the treatment of intractable upper trunk pain in patients with cancer without pulmonary dysfunction.

    Comparison of ventricular drainage in poor grade patients after intracranial hemorrhage
    (Taylor and Francis, 2005-09) Yılmazlar, Selçuk; Abaş, Faruk; Korfalı, Ender; Uludağ Üniversitesi/Tıp Fakültesi/Nöroşirürji Anabilim Dalı.; 0000-0003-3633-7919; AAH-5070-2021; 6603059483; 8546184300; 7004641343
    Objectives: The selection of patients and treatment criteria for acute hydrocephalus and intracranial pressure (ICP) after intracranial hemorrhage remains unclear. In general neurosurgical practice, there is a tendency to use external ventricular drainage (EVD) for the patients. This study was undertaken to analyse the complications and efficiency of the different treatment modalities. Methods: The effects, complications and outcome of ventricular drainage on high ICP and hydrocephalus were analysed retrospectively in 109 patients with intracranial hemorrhage. All the patients were assessed using the Glasgow Coma Scale, computed tomograph and ICP monitoring. We excluded patients over the GCS of 8. All patients underwent a procedure for ICP monitoring plus ventricular cerebrospinal fluid (CSF) drainage. Sixty-one patients were managed with one (single) EVD system; 12 patients needed two EVD systems consecutively, while 23 patients underwent an EVD procedure followed by permanent ventriculoperitoneal (VP) shunt insertion. Thirteen patients were treated only by VP shunt for ventricular drainage. The infection rate and outcome 9 months after hemorrhage were analysed. Results: The infection rates were 8.1% in the one-EVD group, 33.3% in the two-EVD group (one EVD versus two EVD, p < 0.05), 8.6% in the EVD-VPgroup and 7.7% in the VP shunt group. The mortality rates were 73.7% in the one-EVD group, 83.8% in the two-EVD group, 47.8% (p < 0.05) in the EVD-VPgroup and 53.8% (p < 0.01) in the VP shunt group. Discussion: This study indicates that single and short-term use of EVD and/or early VP shunting are associated with a low risk of infection. Furthermore, early VP shunting may protect the brain from the irregular control of intracranial hypertension and may allow more time for resolution of CSF circulation and significantly lowers the mortality rates.

    Neuroprotective effects of postconditioning on lipid peroxidation and apoptosis after focal cerebral ischemia/reperfusion injury in rats
    (Türkiye Nöroşirürji Derneği, 2010-01) Abaş, Faruk; Alkan, Tülin; Gören, Bülent; Taşkapılıoğlu, Özgür; Sarandöl, Emre; Tolunay, Şahsine; Uludağ Üniversitesi/Tıp Fakültesi/Beyin ve Sinir Cerrahisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Fizyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyokimya Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Patoloji Anabilim Dalı.; 0000-0002-2593-7196; ABE-1716-2020; AAH-1718-2021; ABB-8161-2020; AAH-1792-2021; 8546184300; 6601953747; 6602543716; 6506852772; 55943324800; 6602604390
    AIM: Apoptosis after cerebral ischemia/reperfusion (I/R) injury leads to the process of cell death. The deal therapeutic approach would target the apoptosis after I/R. Ischemic postconditioning is a recently discovered neuroprotective strategy that involves the application of brief mechanical reperfusion with a specific algorithm at the onset of reperfusion following an ischemic period. MATERIAL and METHODS: Transient MCAo was performed on male SD (275 +/- 25g) rats with intraluminal thread insertion for 2hrs. Rats (n:36) were treated with postconditioning after 60 minutes of occlusion. The postconditioning algorithm was 30 secs of brief reperfusion followed by 30 secs of MCAo and this cycle was repeated 3 times at the onset of reperfusion. RESULTS: After I/R injury, % change of the malonyldialdehyde (MDA) levels in the cortex, which is an index of lipid peroxidation, was found significantly higher in the I/R group. On the other hand postconditioning upregulated Bcl-2 and Bax translocation to the mitochondria, and caspase-3 activity and also reduced oxidative stress levels. CONCLUSION: These findings indicated this neuroprotective effect is most likely achieved by antiapoptotic mechanisms through caspase pathways.

    Risk factors and complications of intracranial pressure monitoring with a fiberoptic device
    (Elsevier, 2009-02) Bekar, Ahmet; Doğan, Şeref; Abaş, Faruk; Caner, Burcu; Korfalı, Gülşen; Kocaeli, Hasan; Yılmazlar, Selçuk; Korfalı, Ender; Caner, Burcu; Uludağ Üniversitesi/Tıp Fakültesi/Nöroşirürji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Anestezi ve Reanimasyon Anabilim Dalı.; 0000-0003-3633-7919; AAI-6531-2021; AAH-5070-2021; 7102693077; 6603677218; 8546184300; 25027089000; 6701462594; 6603500567; 6603059483; 7004641343
    We prospectively investigated the complications associated with intraparenchymal intracranial pressure (ICP) monitoring using the Camino intracranial pressure device. A fiberoptic ICP monitoring transducer was implanted in 631 patients. About half of the patients (n = 303) also received an external ventricular drainage set (EVDS). The durations (mean +/- SD) of ICP monitoring in patients without and with an EVDS were 6.5 +/- 4.4 and 7.3 +/- 5.1 days, respectively. Infection occurred in 6 patients with only an ICP transducer (6/328, 1.8%) and 24 patients with an EVDS also (24/303, 7.9%). The duration of monitoring had no effect on infection, whereas the use of an EVDS for more than 9 days increased infection risk by 5.11 times. Other complications included transducer disconnection (2.37%), epidural hematoma (0.47%), contusion (0.47%), defective probe (0.31%), broken transducer (0.31%), dislocation of the fixation screw (0.15%), and intraparenchymal hematoma (0.15%). In conclusion, intraparenchymal ICP monitoring systems can be safely used in patients who either have, or are at risk of developing, increased ICP.
