Publication Metadata only Temporal bone measurements on high-resolution computed tomography(B C DECKER INC, 2004) BALTACIOĞLU, FEYYAZ; Ekinci, G; Koc, A; Baltacioglu, F; Veyseller, B; Altintas, O; Han, TThe distances between the important neural and vascular structures in normal temporal bones were measured by using high-resolution computed tomography (HRCT). We examined 100 normal ears in 50 subjects ranging in age from 15 to 72 years (mean age 39 years). We measured the distances from the medial lip of the posterior wall of the internal auditory canal to the medial wall of the vestibule (mean 9.7 mm), from the cochlea to the tympanic segment of the facial canal (mean 1.76 mm), from the medial wall of the vestibule to the lateral aspect of the lateral semicircular canal (mean 8.03 mm), and from the external auditory canal to the lateral sinus (mean 13.2 mm). HRCT examination is the best method for defining the morphology of temporal bone.Publication Metadata only Renal artery stenting in solitary functioning kidneys: Technical and clinical results(ELSEVIER IRELAND LTD, 2006) BALTACIOĞLU, FEYYAZ; Sahin, S; Cimsit, C; Andac, N; Baltacioglu, F; Tuglular, S; Akoglu, EObjective: To evaluate the clinical and technical results of renal artery stenting for the treatment of renovascular hypertension and renal failure in patients with solitary functioning kidney. Materials and methods: Fifteen patients with solitary functioning kidney underwent renal artery stenting and were followed up for 12-60 months. Before the procedures, systolic and diastolic blood pressures and serum creatinine levels were measured and the number of antihypertensive drugs was recorded and followed up after stenting. In case of restenosis, either in-stent percutaneous transluminal renal angioplasty or stent-in-stent placement was performed. Results: Primary technical success rate was 100%. One lesion was nonostial while 14 were ostial. Primary patency rates were 100% for 6 months, 92.3% for 12 months, and 69.2% for 24 months. The secondary patency rate at 24 months was 100%. The differences between the baseline and postprocedural values of systolic blood pressures, diastolic blood pressures and the number of antihypertensive drug were statistically significant (P < 0.05), except the values of serum creatinine. Hypertension was cured in 1 (6.7%) patient, improved in 4 (26.6%) and stabilized in 10 (66.7%) patients. Renal function improved in 9 (60%), stabilized in 4 (26.6%), and deteriorated in 2 (13.4%) patients. Minor complication rate was 13.4% and major complication rate was 13.4%. Conclusion: Revascularization of renal artery stenosis using stent in solitary functioning kidneys is a safe and efficient procedure with high primary technical results, low restenosis rates and acceptable complication rates. It has an improving and controlling effect on blood pressure and renal functions. (c) 2005 Elsevier Ireland Ltd.

Distal middle cerebral artery (MCA) aneurysms constitute approximately 5% of all MCA aneurysms. We report the results of our coil embolization for the treatment of distal MCA aneurysms. Eleven patients (four men and seven women, average age 37 years) with distally located MCA aneurysms were treated. Four of the aneurysms were fusiform in shape and the remainder were saccular. Seven of the aneurysms were in the dominant hemisphere. Four of the seven patients who had saccular aneurysms were treated with selective aneurysm embolization. The remaining seven patients were treated with aneurysmal sac and parent artery coiling. All patients had good retrograde flow into the peripheral branches of the occluded artery. All the procedures were completed successfully without any additional neurological deficits. Coil embolization is a safe and effective technique for the treatment of distal MCA aneurysms. If the parent artery cannot be preserved, pial collaterals can supply adequate blood to prevent neurological deficits.Publication Metadata only Transarterial glue embolization in iatrogenic renovascular injuries(SPRINGER, 2008) BALTACIOĞLU, FEYYAZ; Cimsit, Nuri Cagatay; Baltacioglu, Feyyaz; Cengic, Ismet; Akpinar, Ihsan Nuri; Ilker, Yalcun; Turkeri, LeventIatrogenic injuries of the intrarenal arterial system include pseudoaneurysms and fistulas. They can cause hematuria and life-threatening hemodynamic instability, and therefore should be treated promptly. Endovascular treatment is recommended for these cases due to its effectiveness. Among the different agents used for embolization, n-butyl-2-cyanoacrylate (glue) has rarely been used. We present 15 patients with pseudoaneurysms and/or arteriovenous or caliceal fistulas who were treated by glue embolization. In our patient group, five had a history of percutaneous nephrolithotomy, six had renal biopsies, three had nephron-sparing surgery, and one had percutaneous nephrostomy. Glue embolizations were performed with the microcatheter technique. All patients were successfully treated, and all but one had excellent follow-ups. One patient suffered from disseminated intravascular coagulation secondary to transfusion and died after the procedure. We think glue embolization is a safe and effective treatment for this group of patients and present our experience along with the technical approach.Publication Metadata only MR imaging, CT, and angiography features of endolymphatic sac tumors: report of two cases(SPRINGER, 2002) BALTACIOĞLU, FEYYAZ; Baltacioglu, F; Ekinci, G; Ture, U; Sav, A; Pamyr, N; Erzen, CLow-grade adenocarcinoma of endolymphatic sac origin is a rare tumor of the temporal bone. There are some difficulties in its differential diagnosis from other vascular and non-vascular tumors of the temporal bone. However its radiological differentiation from other tumors of the temporal bone is important for surgical planning. We present a report on two endolymphatic sac tumors with some specific radiological findings which can support a correct diagnosis.Publication Metadata only Fat necrosis mimicking liposarcoma in a patient with pelvic lipomatosis. CT findings(2003) BALTACIOĞLU, FEYYAZ; Andaç, Nurten; Baltacioglu, Feyyaz; Cimşit, N. Cagatay; Tüney, Davut; Aktan, OzdemirPelvic lipomatosis is a rare condition characterized by an overgrowth of normal fat in the perirectal and perivesical spaces. The most important differential diagnosis is liposarcoma. We present a case of pelvic lipomatosis associated with a mass, which was diagnosed radiologically as a liposarcoma, but surgical biopsy result revealed fat necrosis.Publication Open Access Intraarterial thrombolysis with r-tPA for treatment of anterior circulation acute ischemic stroke - Technical and clinical results(SAGE PUBLICATIONS INC, 2003-09) BALTACIOĞLU, FEYYAZ; Baltacioglu, F; Afsar, N; Ekinci, G; Tuncer-Elmaci, N; Cimsit, NC; Aktan, S; Erzen, CTo investigate factors effecting the safety and recanalization efficacy of local intraarterial (IA) recombinant tissue plasminogen activator (r-tPA) delivery in patients with acute ischemic stroke. Eleven patients with anterior circulation acute ischemic stroke were treated. The neurological status of the patients were graded with the Glasgow Coma Scale (GCS) and National Institute of Health Stroke Scale (NIHSS). All patients underwent a computed tomography (CT) examination at admission. In addition four patients had diffusion-weighted and one patient had a perfusion magnetic resonance (MR) examinations. Patients were treated within six hours from stroke onset. Immediate, six hours, and 24 hours follow-up CT examinations were performed in order to evaluate the haemorrhagic complications and the extent of the ischemic area. The Rankin Scale (RS) was used as an outcome measure. Two of the 11 patients had carotid T occlusion (CTO), nine had middle cerebral artery (MCA) main trunk occlusion. Four patients had symptomatic haemorrhage with a large haematoma rupturing into the ventricles and subarachnoid space. Of these, three patients died within 24 hours. The remaining seven patients had asymptomatic haematomas that were smaller compared to symptomatic ones, and showed regression in size and density on follow-up CTs. At third month five patients had a good outcome and three patients had a poor outcome. In acute ischemic stroke, local IA thrombolysis is a feasible treatment when you select the right patient. Haemorrhage rate does not seem to exceed that occuring in the natural history of the disease and in other treatment modalities.Publication Metadata only Transsphenoidal (large craniopharyngeal) canal associated with a normally functioning pituitary gland and nasopharyngeal extension, hyperprolactinemia, and hypothalamic hamartoma(AMER ROENTGEN RAY SOC, 2003) BALTACIOĞLU, FEYYAZ; Ekinci, G; Kilic, T; Baltacioglu, F; Elmaci, I; Altun, E; Pamir, MN; Erzen, CPublication Metadata only Inguinoscrotal bladder herniation: is CT a useful tool in diagnosis?(2002) BALTACIOĞLU, FEYYAZ; Andaç, Nurten; Baltacioğlu, Feyyaz; Tüney, Davut; Cimşit, N. Cagatay; Ekinci, Gazanfer; Biren, TuğrulUrinary bladder herniation into the inguinal canal is a rare occurrence. The condition is often diagnosed during inguinal hernia surgery. We present a rare case of inguinoscrotal bladder herniation with its computed tomography findings.Publication Metadata only Approach to fragmented central venous catheters(SAGE PUBLICATIONS LTD, 2005) YILDIZELİ, BEDRETTİN; Yildizeli, B; Lacin, T; Baltacioglu, F; Batirel, HF; Yuksel, MProlonged venous access devices are needed in cancer patients for central venous access. Catheter fragmentation leading to catheter malfunction represents a rare problem. Herein we present our experience in the management of fragmented catheters. Between 2001 and 2003, 183 catheters were placed via the subdavian vein, and five cases of fragmented catheters were observed. Fragments were removed by an Amplatz gooseneck snare (Microvena, St. Paul, MN) with angiographic intervention. The diagnosis of the breakage was made by chest radiography.The incidence of catheter breakage was 2.7%. All fragments were removed by the snare, without any complications. Catheter narrowing and breakage owing to its medial positioning in the subdavian vein were the main causes of catheter malfunction. In any case of catheter malfunction, radiologic evaluation of the catheter must be done to rule out its rupture. Removal of the fragments using the Amplatz snare is a safe and easily applied procedure.
