Publication Metadata only Acute Obstructive Hydrocephalus due to a Giant Posterior Cerebral Artery Aneurysm in a Pediatric Patient(S. Karger AG, 2018) DAĞÇINAR, ADNAN; Sarica C., Tanrikulu B., Sahin Y., Daǧçlnar A., Baltacioglu F., Bayri Y.Introduction: Intracranial aneurysms are very rare in children. Although subarachnoidal hemorrhage (SAH) is by far the most common presentation of aneurysms in the majority of the pediatric case series, it is not rare for an unruptured aneurysm to present with a mass effect. Acute hydrocephalus is a common finding following aneurysmal SAH. However, this malady may develop even in the absence of SAH but secondary to direct obstruction by a giant aneurysm. This situation is extremely rare in children, with only a few known case reports in the literature. Case Report: We report the case of a 10-year-old girl who presented with signs and symptoms of acute hydrocephalus; further radiological evaluation revealed obstructive hydrocephalus and a giant posterior cerebral artery aneurysm. Following endovascular treatment of the aneurysm, hydrocephalus was completely resolved, and the patient was symptom free. Conclusion: Although they are very rare, giant intracranial aneurysms must be kept in mind during the differential diagnosis of pediatric acute hydrocephalus cases. Hydrocephalus may resolve spontaneously after the successful treatment of these aneurysms. © 2018 S. Karger AG, Basel.

This study aims to evaluate the feasibility and efficacy of ACCLINO 1.9 F and ACCLINO Flex stent systems, designed for use as adjunctive products in coil embolization of intracranial aneurysms. Case files of 47 patients, and 52 aneurysms in total, treated with at least one ACCLINO 1.9 F or ACCLINO Flex stent were retrospectively evaluated. Technical success, complications, and angiographic outcomes were assessed based on immediate post-procedural controls along with 6th and 12th month angiograms. Mechanical untoward event rate, including asymptomatic complications, is 9.6 % (five out of 52 aneurysms). Failed dual-stenting attempt rate is 15.4 % (two out of 13). Overall procedure-related morbidity is 4.2 % with no neurologic sequelae. Initial occlusion rate is 90.4 % (47 aneurysms). One patient had residual filling in the aneurysm neck, which was stable throughout follow-up. The remaining four cases had spontaneous follow-up occlusion. Recanalization rate at 6th month is 2.1 % with one aneurysm requiring retreatment. One patient was lost to follow-up. There is no mortality associated with treatment. Stent-assisted coil embolization with ACCLINO stents in single or dual configurations is a feasible treatment option for challenging intracranial aneurysms. Follow-up results are encouraging; techniques were effective in complex cases and there were no clinically significant adverse outcomes.Publication Metadata only Transarterial microcatheter glue embolization of the bronchial artery for life-threatening hemoptysis: Technical and clinical results(ELSEVIER IRELAND LTD, 2010) BALTACIOĞLU, FEYYAZ; Baltacioglu, Feyyaz; Cimsit, Nuri Cagatay; Bostanci, Korkut; Yuksel, Mustafa; Kodalli, NihatObjectives: To report our experience with transarterial glue embolization of the bronchial artery for life-threatening hemoptysis. Materials and methods: Twenty-five patients underwent bronchial artery embolization, using coaxial microcatheter technique, with a liquid agent, n-butyl-2-cyanoacrylate (NBCA), named glue, for life-threatening hemoptysis. The technical and clinical outcomes were followed in terms of immediate control of bleeding, recurrence of hemoptysis and complications of the procedure. Results: Four patients had acute hemoptysis when they were evaluated. The average number of arteries embolized per patient was 2.9. BAEs were successful in controlling hemoptysis immediately in all 25 patients (100%) and in 24 patients (96%) at 1 month follow-ups. One patient had recurrent hemoptysis on the tenth day after embolization. The follow-up time ranged from 2 to 63 months (mean 14 months). Six patients (25%) died all as a result of their disease process. Bleeding recurred in 3 patients after 30 days (7th, 11th, 12th months). One patient had vomitting attacks with dysphagia after the procedure that lasted 24 h. Three patients had transient thoracic pain lasting 3-5 days. There were no procedure related spinal or vascular complications. Conclusions: Glue embolization with microcatheter technique is a safe and effective treatment in cases of life-threatening hemoptysis with a very high rate of success and low rate of complications.

In this retrospective multicenter study, we analyzed the safety and efficacy of the treatment of intracranial, unruptured, or previously treated but recanalized aneurysms using Flow Re-Direction Endoluminal Device (FRED) Jr with emphasis on midterm results. Materials and Methods: Clinical and radiological records of 150 patients harboring 159 aneurysms treated with FRED Jr at six centers between October 2014 and February 2020 were reviewed and consecutively included. Clinical outcome was measured by using the modified Rankin Scale (mRS). Anatomical results were assessed according to the O'Kelly-Marotta (OKM) scale and the Cekirge-Saatci Classification (CSC) scale. Results: The overall complication rate was 24/159 (16%). Thrombotic-ischemic events occurred in 18/159 treatments (11%). These resulted in long-term neurological sequelae in two patients (1%) with worsening from pre-treatment mRS 0–2 and mRS 4 after treatment. Complete or near-complete occlusion of the treated aneurysm according to the OKM scale was reached in 54% (85/158) at 6-month, in 68% (90/133) at 1-year, and in 83% (77/93) at 2-year follow-up, respectively. The rates of narrowing or occlusion of a vessel branch originating from the treated aneurysm according to the CSC scale were 11% (12/108) at 6-month, 20% (17/87) at 1-year, and 23% (13/57) at 2-year follow-up, respectively, with all cases being asymptomatic. Conclusions: In this retrospective multicenter study, FRED Jr was safe and effective in the midterm occlusion of cerebral aneurysms. Most importantly, it was associated with a high rate of good clinical outcome.Publication Open Access Super-Selective Embolization of Vesical Arteries with Micro-Catheter Technique in the Treatment of Intractable Hemorrhage due to Bladder Cancer(GALENOS YAYINCILIK, 2016-03-30) BALTACIOĞLU, FEYYAZ; Sahin, Bahadir; Sulukaya, Muhammed; Tinay, Ilker; Tanidir, Yiloren; Baltacioglu, Feyyaz; Turkeri, LeventObjective: We aimed to share our experience about the super-selective embolization of the vesical artery performed with micro-catheter technique which was used as a palliative approach to control intractable hematuria in patients with bladder cancer. Materials and Methods: Super-selective embolization of the vesical artery with micro-catheter technique was performed in 12 bladder cancer patients whose hematuria could not be controlled with other palliative methods in our clinic. Hemoglobin levels, blood transfusion amounts, complications and urethral catheter removal duration before and after embolization were evaluated. Results: The average age of the patients was 73.3 (65-85, range) years. For the embolization process, n-butyl-2cyaboacrylate (glue) was used as the primary method in 3 patients and polyvinylalcohol (PVA) particle was used in the remaining 9 patients. In two of the patients whose hematuria could not be controlled after PVA embolization glue embolization was performed as the secondary procedure within one week. Super-selective embolization of the vesical artery with micro-catheter technique was performed in all of our cases. In 4 cases, embolization of the vesical artery was performed only to the side of the tumor, which was determined with cystoscopy. Bilateral embolization was performed to the remaining 8 cases. The average hemoglobin value before and after the embolization procedure was 7.9 g/dL and 9.2 g/dL, respectively. The average blood transfusion amounts before and after the procedure were 4 (2-15) and 2.3 (1-4) units erythrocyte/whole blood, respectively. The average urethral catheter duration after the procedure was 7 (2-16) days in 10 patients, who were treated one single embolization session. Urethral catheters were removed once the hematuria dissolved completely. There were no major complications or mortality related to the treatment after the embolization procedure. Conclusion: Super-selective embolization of the vesical artery performed with micro-catheter technique is a safe and effective alternative in patients with intractable hematuria due to bladder cancer whose hematuria could not be controlled with other palliative methods.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.

A study of 3.0-Tesla lumbar MRI comparing skeletal, neural, and vascular markers(ELSEVIER SCIENCE INC, 2014) TÜRELİ, DERYA; Tureli, Derya; Ekinci, Gazanfer; Baltacioglu, FeyyazPurpose: This study aimed to determine the reliability of the iliolumbar ligament (ILL), 12th costa, aortic bifurcation (AB), Tight renal artery (RRA), and conus medullaris (CM) for numbering of vertebral segments. Subjects and methods: Five hundred five patients underwent routine lumbar MRI examinations including a cervicothoracic sagittal scout and T1 and T2-weighted sagittal and axial turbo spin echo images. Images were evaluated by two radiologists separately. Results: The identifiability of ILL and 12th costa were 85.7% and 48.1%. AB, RRA, and CM were located more caudally in lumbarized S1 and more cranially in sacralized L5 cases. Conclusion: Landmarks suggested by previous studies are not reliable alternatives to cervicothoracic scout images due to wide ranges of distribution and inconsistencies in identification.

Unfortunately, a significant part of 90Y-labeled microspheres may shunt to the lungs after intraarterial injection. It can be predictable by infusing technetium-99 m-labeled macro-aggregated albumin particles through a catheter placed in the proper hepatic artery depending on the lobe to be treated with performing a quantitative lung scintigraphy. Radiation pneumonitis (RP) can occur 1 to 6 months after the therapy, which is a rare but severe complication of SIRT. Prompt timing of steroid treatment is important due to its high mortality rate. On the other hand, pulmonary diffusion capacity measured by carbon monoxide (DLCO) is an excellent way to measure the diffusing capacity because carbon monoxide is present in minimal amount in venous blood and binds to hemoglobin in the same manner as oxygen. Some authors reported that the most consistent changes after radiation therapy (RT) are recorded with this quantitative reproducible test. The relationship between the proportional reductions in DLCO and the severity of RP developing after this therapy may prove to be clinically significant. Case presentation We herein present a patient who developed RP after SIRT that could be quantified using DLCO. To the best of our knowledge, this case is the first who developed unexpected RP after SIRT with significant decrease in DLCO with internal radiation exposure. Conclusions RP is a very rare complication and may lead to a fatal outcome. Decline in DLCO could be a valuable parameter for follow-up and to identify potential candidates for RP and could be also another trigger for administration of steroid therapy with prompt timing in this patient group.Publication Open Access Resistant pediatric priapism: A real challenge for the urologist(CANADIAN UROLOGICAL ASSOCIATION, 2015-08-10) ŞEKERCİ, ÇAĞRI AKIN; Sekerci, Cagri Akin; Akbal, Cem; Sener, Tarik Emre; Sahan, Ahmet; Sahin, Bahadir; Baltacioglu, Feyyaz; Simsek, FerruhPriapism in pediatric patients is a rare entity. We present an 8-year-old boy with known cerebral palsy. He came to the emergency department with sustained painful erection for 12 hours. Physical examination showed rigid penis. Blood count and biochemical analysis were normal. Although penile Doppler ultrasound revealed normal arterial and venous flow, cavernosal blood gas was hypoxic. A total of 50 mL of dark blood was aspirated, and 2 mL of 0.001% adrenalin solution was applied to both corpus cavernosum, twice within 20 minutes, which eventually did not achieve detumescence. A distal Winter shunt was performed at the end of which the penis was semi-flaccid. By the 18th hour of surgery, the penis re-gained painful erection status, so an Al-Ghorab shunt was performed. After the Al-Ghorab shunt, the penis was still in the semi-flaccid state. The next day, an angiography was performed and an arteriovenous fistula was discovered and treated by embolization. The flaccid state was achieved and the patient was discharged the day after the embolization.
