Öğe APPENDIX INVAGINATION MIMICKING ILEOCECAL INTUSSUSCEPTION IN A PEDIATRIC PATIENT: A CASE REPORT(Elsevier Science Inc, 2016) Aybay, Muhsin Nuh; Erol, Seyit; Kaya, Hasan Emin; Guler, IbrahimBackground: Appendix invagination is a rare cause of right lower quadrant abdominal pain. Clinical findings are not specific and can mimic a wide range of diseases. Case Report: An 8-year-old girl was admitted with abdominal pain lasting for 2 weeks. Clinical and radiologic findings suggested ileocecal intussusception initially. A failed hydrostatic reduction attempt and subsequent abdominal ultrasound and computed tomography studies showed that the underlying pathology was invagination of the vermiform appendix. The patient was managed conservatively and spontaneous reduction was observed during follow-up. She underwent appendectomy 9 months later due to chronic appendicitis. Why Should An Emergency Physician Be Aware of This?: Appendix invagination should be kept in mind while evaluating patients with suspected ileocecal intussusception. In distinguishing between these two conditions, a blind-ending invaginating segment is an important clue in favor of appendix intussusception. (C) 2016 Elsevier Inc.

Purpose To determine the prevalence of possible etiologies other than SI and frequency of incidental findings demonstrated on sacroiliac MRI examinations in a cohort of patients with lower back pain and suspected SI. Material and Methods Sacroiliac MRI examinations of 1421 patients with suspected SI were retrospectively reviewed. In patients without SI findings, other potential causes for lower back pain and incidental findings were documented. Results SI was present in 535 of 1421 patients (37.6%). In 886 of the patients whose MRI studies were negative for SI, other possible causes for lower back pain or incidental findings were seen in 386 (43.5%). The most common musculoskeletal (MSK) finding was lumbosacral transitional vertebra (8.6%) followed by findings suggesting piriformis syndrome (4.2%), spondylosis (3.7%), and sacral insufficiency fractures (1.8%). The most common non-MSK findings were follicular cysts (15.3%) and uterine fibroids (4.9%). Conclusion In patients with suspected SI but negative MRI examinations for SI, some other possible causes for lower back pain and several incidental findings can be seen on imaging. The presence of these findings may explain the patient's symptoms, and awareness of these conditions may be helpful in patient management and individualizing treatment.Öğe İntrakraniyal anevrizmaların endovasküler tedavisinde woven endobridge (WEB) kullanımı: Retrospektif bir değerlendirme(Necmettin Erbakan Üniversitesi Meram Tıp Fakültesi, 2018) Kaya, Hasan Emin; Koç, OsmanWoven EndoBridge (WEB) özellikle geniş boyunlu bifurkasyon anevrizmalarında kullanılan görece yeni bir tedavi modalitesidir. Çalışmamızın amacı hastanemizin WEB deneyimini sunmaktır. Yöntem: Eylül 2014 – Eylül 2017 tarihleri arasında intrakraniyal anevrizmaları hastanemizde WEB ile tedavi edilen 35 hasta çalışmaya dahil edilmiştir. Tedavi sonrası ortalama 10 ay (aralık: 1 – 33 ay) takip edilen edilen hastaların oklüzyon oranları MR anjiyografi ve dijital subtraksiyon anjiyografisi ile değerlendirilmiştir. Bulgular: Yirmi kadın, on beş erkek hastaya (ortalama yaş: 55; aralık: 32 – 76) ait 35 anevrizma (ortalama çap: 6,4 mm; aralık: 3,5 – 12 mm) WEB ile tedavi edilmiştir. Anevrizmaların 30'unda (%85) boyun ≥4 mm olarak bulunmuştur. Anevrizmaların 24'ü (%68) orta serebral arter bifurkasyonu, 5'i (%14) baziler tepe, 4'ü (%12) anterior komunikan, biri (%3) internal karotid arter tepe, biri de (%3) orta serebral arter M1 segmenti yerleşimli idi. Üç hastada rüptüre bağlı subaraknoid kanama vardı. Vakaların hepsinde cihaz başarılı bir şekilde yerleştirilebilmiştir. Takip incelemeleri olan 24 hastanın 23'ünde (%95) yeterli oklüzyon tespit edilmiştir. Bir hastada anevrizma kalıntısı saptanmış ve hasta akım çevirici stent ile tedavi edilmiştir. Hastalarda tedaviye bağlı morbidite ya da mortalite saptanmamıştır. Sonuç: Görece yeni bir modalite olduğu için uzun dönem takip verileri henüz mevcut olmamakla beraber WEB'in özellikle geniş boyunlu bifurkasyon anevrizmaları için orta vadeli takiplerde güvenli ve etkin bir tedavi modalitesi olduğu görülmektedir.

Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive and reliable method for demonstrating the normal IHBD anatomy and its variations. This retrospective study aimed to identify and classify novel variations, except those already reported in the literature, using MRCP. METHODS MRCP examinations, which were conducted in two different centers in the last five years, were retrospectively evaluated. IHBD variations were recorded with respect to the Yoshida classification. In addition, newly detected variations that were not included in this classification were identified and classified. RESULTS MRCP examinations of 2624 patients were screened, and 2143 were determined to be eligible for evaluation. Of 2143 patients, 987 were males (average age, 54 +/- 18 years) and 1156 were females (mean age, 57 +/- 17 years). In this study, 10 novel variations that were not included in the Yoshida classification were identified in 14 patients. CONCLUSION MRCP is an effective, reliable, and noninvasive imaging method for evaluating the IHBD anatomy and its variations. Novel variations described in this study may help to better understand the biliary anatomy.Öğe Magnetic resonance cholangiopancreatography evaluation of intrahepatic bile duct variations with updated classification(2016) Nayman, Alaaddin; Özbek, Orhan; Erol, Seyit; Karakuş, Hayrettin; Kaya, Hasan EminPURPOSE Preoperative detection of intrahepatic bile duct (IHBD) variations is essential to reduce surgical mor-bidity and mortality rates.
