Öğe Clinically palpable breast abnormalities with normal imaging: Is clinically guided biopsy still required?(W B Saunders Co Ltd, 2012) Gumus, H.; Gumus, M.; Mills, P.; Fish, D.; Devalia, H.; Jones, S. E.; Jones, P. A.AIM: To determine the need for a fine-needle or core biopsy in patients with clinically palpable breast abnormalities who have negative mammographic and sonographic findings. METHOD AND MATERIALS: Over a 12-year period, 251 patients with a palpable abnormality at presentation and who had a negative ultrasound and mammogram underwent clinically guided biopsy (CGB) by breast surgeons. This was 2.7% (251/9313) of all breast biopsies performed from January 1999 to December 2010. Physical findings were qualitatively categorized into five groups as clinically normal, benign, probably benign, suspicious, and malignant at the time of initial assessment. The number of biopsies for each category and biopsy results were analysed retrospectively. RESULTS: Three (1.2%) of the 251 CGBs were reported as malignant; two (0.8%) of which were invasive. Forty-six (18.3%) of the 251 cases were regarded as clinically suspicious or malignant while the remaining 215 examinations were categorized as benign or probably benign. All three malignancies were in the clinically suspicious or malignant group. CONCLUSION: A negative ultrasound and mammogram in patients with a palpable abnormality does not exclude breast cancer; however, the likelihood is very low (1.2%). In this study, 81.7% of biopsies (205/251) could have been avoided if CGB was reserved for the clinically suspicious or malignant group only without missing any malignancies.

Materials and Methods: According to hospital records, between January 2009 and April 2010, 314 consecutive patients underwent pulmonary CT angiography (CTPA) and coronary CT angiography. The CT films from these patients were retrospectively analyzed. Results: Under normal conditions, the middle pulmonary vein (MPV) drains into the left atrium either by the direct or indirect route. Direct (37 patients, 11.8%) drainage means that the MPV does not drain into the upper or lower pulmonary veins but instead drains directly into the right pulmonary vein system. In contrast, indirect (276 patients, 87.9%) drainage occurs when the MPV drains into the upper or lower pulmonary veins. In this study, 12 different variations in drainage patterns were found. Conclusion: Increasing the number of patients may have led to the identification of additional variants. However, clinically important variations are rarely seen. Correct mapping of the MPV is very important for cardiologists and for surgeons in order to provide the best treatment and avoid complications.Öğe The Role of MRI in Intraarticuler application of Beta-emitting Radionuclides in the Treatment of Haemophilic Joint Diseases(Springer, 2009) Kaya, H.; Bellur, B. Kizilkan; Ayyildiz, O.; Aguloglu, N.; Gumus, H.; Kapukaya, A.[Abstract Not Available]Öğe Variations of the celiac trunk and hepatic arteries: a study with 64-detector computed tomographic angiography(Verduci Publisher, 2013) Gumus, H.; Bukte, Y.; Ozdemir, E.; Senturk, S.; Tekbas, G.; Onder, H.; Ekici, F.OBJECTIVES: The aim of the present study was to evaluate variations in celiac trunk and hepatic artery with multi-detector computed tomography (MDCT). PATIENTS AND METHODS: Totally 820 patients who underwent angiography of the abdominal aorta were evaluated. Anatomical findings were grouped according to the Michels classification. RESULTS: Several variations and/or anomalies were noted in 33.2% of the patients (n=272). The most common abnormality was Michels type III (10.1%), followed by type V (7.3%), type II (4.7%) and others. Type X was not observed in our series. We have noted additional, previously unclassified variations in 12 cases (1.5%). CONCLUSIONS: Preoperative knowledge of variant anatomy may assist in the selection of treatment options and surgical planning, which in turn facilitates surgical dissection and helps avoiding iatrogenic injury. MDCT angiography allows detailed visualization of the vascular anatomy.
