Publication Metadata only The effect of smoking cessation on the technical success of endovascular treatment for thromboangiitis obliterans(Elsevier Inc., 2023) Gündoğmuş, Cemal Aydin; Samadli, Vugar; Sorkun, Mine; Oğuzkurt, Levent; Doctor; Doctor; Researcher; Faculty Member; N/A; N/A; School of Medicine; School of Medicine; Koç University Hospital; Koç University Hospital; N/A; N/A; 327628; 13559Purpose: To show that smoking cessation improves the technical success of lower extremity endovascular treatment in patients with thromboangiitis obliterans (TAO). Materials and Methods: One hundred two patients with TAO who underwent endovascular treatment for chronic limb-threatening ischemia or severe claudication of lower extremities in a tertiary hospital between 2015 and 2022 were included in this retrospective study. Data on serum cotinine levels were available for the last 45 patients, and 38 patients constituted the study population. Per the institution's protocol, patients were instructed to quit smoking 15 days before the intervention. However, cotinine levels showed that some of the patients continued smoking. Technical and recanalization successes were assessed as the primary end points. The secondary end point was the improvement in Rutherford scores at the 1-month follow-up. The McNemar test was used to compare the proportion of recanalized arteries after the intervention. Results: Thirty-seven men and 1 woman (mean age, 42.9 years ± 10.1) were evaluated. The overall technical success rate was 86.8% in the study group. The technical success rate was significantly higher in the nonsmoker group (n = 24 [96%]) than in the smoker group (n = 8 [61.5%]; P = .006). One-month clinical data were available for 100% of the patients. The Rutherford category of the nonsmoker group was significantly lower at the 1-month follow-up. In addition, the Wilcoxon signed-rank test revealed lower Rutherford scores after the intervention in the nonsmoker group. The adverse event rate was 8%. One (2.7%) patient in the smoker group underwent a minor amputation. Conclusions: Cessation of smoking before endovascular therapy improved technical success and recanalization rates in patients with TAO.Publication Open Access An intrathyroidal nodule consisting of papillary thyroid cancer and ectopic hyperechoic parathyroid adenoma: a case report(Iuliu Hatieganu Medical Publishing House, 2021) Altınmakas, Emre; Güneyli, Serkan; Kabaalioğlu, Adnan; Çil, Barbaros Erhan; Samadli, Vugar; Doğan, Hakan; Taşkın, Orhun Çığ; Özışık, Seçil; Ağcaoğlu, Orhan; Faculty Member; Researcher; Faculty Member; Doctor; Faculty Member; School of Medicine; Koç University Hospital; N/A; N/A; 169993; N/A; 327614; 166686; N/A; 175476A 53-year-old woman with fatigue lasting for 6 weeks and increased parathormone level underwent a neck ultrasound. It revealed a large, lobulated, solid intrathyroidal nodule consisting of hypoechoic component with microcalcifications and hy-perechoic component with vascularity on Doppler mode. There were also subcentimetric intrathyroidal hypo- and hyperechoic nodules. Upon the diagnosis of papillary thyroid cancer on fine-needle aspiration biopsy, a total thyroidectomy procedure was performed. In the histopathologic evaluation, the hypoechoic component was diagnosed as papillary thyroid cancer, while the hyperechoic component was diagnosed as ectopic parathyroid adenoma. Subcentimetric nodules were demonstrated as multi-foci of papillary thyroid cancer.
