Öğe Contralateral subdural effusion after aneurysm surgery and decompressive craniectomy: case report and review of the literature(Elsevier Science Bv, 2005) Kilincer, C; Simsek, O; Hamamcioglu, MK; Hicdonmez, T; Cobanoglu, SWe report a complication of decompressive craniectomy in the treatment of aneurismal subarachnoid hemorrhage (SAH) and accompanying middle cerebral artery (MCA) infarction. A 56-year-old man presented with subarachnoid hemorrhage and right sylvian hematoma. He was diagnosed with high-grade SAH and medical therapy was employed. He showed rapid clinical deterioration on day 9 of his admission. Computed tomographic scans showed right MCA infarction and prominent midline shift. Because of the patient's rapidly worsening condition, further evaluation to find origin of SAH could not be obtained, and decompressive right hemicraniectomy was performed. During sylvian dissection, right middle cerebral and posterior communicant artery aneurysms were detected and clipped. One week after operation, a contralateral frontoparietal subdural effusion and left to right midline shift was detected and drained through a burr-hole. Through successive percutaneous aspirations, effusion recurred and complete resolution was achieved after cranioplasty and subduroperitoneal shunt procedures. Decompressive craniectomy is generally accepted as a technically simple operation with a low incidence of complications. In the light of this current case, we hypothesize that a large craniectomy may facilitate the accumulation of recurrent effusion on contralateral side creating a resistance gradient between two hemispheres. This point may be especially true for subarachnoid hemorrhage cases requiring aneurysm surgery. We conclusively suggest that subdural effusions may be resistant to simple drainage techniques if a large contralateral craniectomy does exist, and early cranioplasty may be required for treatment in addition to drainage procedures.

Although surgical decompression of large hemispheric infarction is often a life-saving procedure, many patients remain functionally dependent. The aims of this study were to identify specific factors that can be used to predict functional outcome, thus establish predictive criteria to reduce poor surgical results. Method. In this non-randomized prospective study, we performed decompressive craniectomy in 32 patients (age range, 27 to 77 years) with large hemispheric infarctions. Based on their modified Rankin Score (RS), which was calculated 6 months postoperatively, patients were divided into two functional groups: good (RS 0-3, n = 7) and poor (RS 4-6, n = 25). The characteristics of the two groups were compared using statistical analysis. Findings. One-month mortality was 31%. However, most of the surviving patients were severely disabled (RS 4 or 5), and 6-month total mortality reached 50%. Increased age (>= 60 years) (P = 0.010), preoperative midline shift greater than 10 mm (P = 0.008), low preoperative Glasgow Coma Score (GCS <= 7) (P = 0.002), presence of preoperative anisocoria (P = 0.032), early (within the first three days of the stroke) clinical deterioration (P = 0.032), and an internal carotid artery infarct (P = 0.069) were the positive predictors of a poor outcome. Interpretation. We view decompressive craniectomy for space-occupying large hemispheric infarction as a life-sparing procedure that sometimes yields good functional outcomes. A dominant hemispheric infarction should not be an exclusion criterion when deciding to perform this operation. Early operation and careful patient selection based on the above-mentioned factors may improve the functional outcome of surgical management for large hemispheric infarction.Öğe Large intradiploic growing skull fracture of the posterior fossa(Springer, 2006) Hamamcioglu, MK; Hicdonmez, T; Kilincer, C; Cobanoglu, SGrowing skull fractures (GSFs) are rare complications of head injury and mostly occur in infancy and early childhood. Location in the posterior fossa and intradiploic development of a GSF is very uncommon. We report a 7-year-old boy with a large, 9x7x4-cm, occipital intradiploic GSF. The lesion developed progressively over a period of 5 years following a documented occipital linear fracture. This case of a GSF developing from a known occipital linear fracture demonstrates that a GSF may reach a considerable size and, although uncommon, intradiploic development and occipital localization of a GSF is possible.Öğe Pituitary metastasis mimicking a macroadenoma from carcinoma of the larynx: A case report(Pensiero Scientifico Editor, 2001) Uzal, MC; Kocak, Z; Doganay, L; Tokatli, F; Caloglu, M; Kilincer, CMetastatic tumors of the pituitary gland are not commonly diagnosed during life in cancer patients. The occurrence of symptomatic lesions is also very unusual and difficult to differentiate clinically and radiologically from pituitary adenomas. Furthermore, a single intrasellar metastasis from laryngeal carcinoma mimicking a pituitary adenoma is an extremely rare pathological finding. We report on the clinical, radiological, and pathological findings in a patient with laryngeal carcinoma who had a symptomatic solitary pituitary gland metastasis that was recognized antemortem.Öğe Recovery from aphasia after decompressive surgery in patients with dominant hemispheric infarction(Lippincott Williams & Wilkins, 2005) Asil, T; Utku, U; Balci, K; Kilincer, C[Abstract Not Available]Öğe Surgical management of combined stab injury of the spinal cord and the aorta -: Case report(Japan Neurosurgical Soc, 2004) Simsek, O; Kilincer, C; Sunar, H; Hamamcioglu, MK; Canbaz, S; Çobanoglu, S; Duran, EA 32-year-old man presented with a combined penetrating stab injury of the spinal cord and the aorta caused by a knife wound in his back at the low thoracic level. The knife had broken, and part of the blade had been retained in the wound, passing through the spinal canal and into the aortic lumen. The patient was treated in two steps: the aorta was repaired by a thoracotomy, then spinal exploration was carried out through a laminectomy. Because of the tamponade effect of the foreign body, it was necessary to delay removal of the blade until vascular control had been achieved. Any sign of a penetrating body passing through the spine should suggest careful evaluation to detect any visceral injury, and multidisciplinary treatment should be planned.
