    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, Nihat
    Objectives: 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.

    Do Nuss bars compromise the blood flow of the internal mammary arteries?
    (OXFORD UNIV PRESS, 2013-09) YILDIZELİ, BEDRETTİN; Yuksel, Mustafa; Ozalper, Mehmet Hakan; Bostanci, Korkut; Ermerak, Nezih Onur; Cimsit, Cagatay; Tasali, Nuri; Yildizeli, Bedrettin; Batirel, Hasan Fevzi
    OBJECTIVES: Minimally invasive repair of pectus excavatum, the so-called Nuss procedure, has become a popular technique in recent years. The internal mammary arteries (IMAs) lie on the posterolateral surface of the sternum, and the Nuss bar is likely to obstruct the blood flow in these arteries. This obstruction could become important in the later stages of the lives of these young people if they were to require coronary artery bypass grafting. The goal of this study is to investigate the extent of obstruction of the IMAs caused by Nuss bars. METHODS: Data were collected prospectively on all patients who underwent the Nuss procedure between October 2011 and May 2012. Patients with a history of pectus excavatum repair by open surgery and those who were younger than 16 years of age were excluded. Computed tomography-angiography (CTA) was performed for the detection of IMA blood flow preoperatively and on the 10th postoperative day. Blood flow in the IMAs was evaluated blindly by two radiologists and classified as blood flow unaffected (group I) or affected (group II) by comparing the assessment of preoperative and postoperative CTAs. The patients in group II were also categorized as having blood flow obstructed bilaterally, blood flow obstructed unilaterally and others (diminished unilaterally/diminished on one side or obstructed on the other side). RESULTS: Thirty-four patients (31 male and three female; mean age 20.7 +/- 4.2 years) underwent surgery. Blood flow was affected in 15 patients (44%), with bilateral obstruction in five, unilateral obstruction in seven, and unilateral diminished flow in two patients. In one patient, blood flow was diminished on one side and obstructed on the other. There was no significant difference between unaffected group I patients and affected group II patients in terms of sex, age, type of deformity, Haller index and the number of bars placed. CONCLUSIONS: Nuss bars cause pressure on the IMAs, but a risk factor for this effect could not be identified. This is a relatively common clinical consequence of minimally invasive repair of pectus excavatum, and the long-term effects will be apparent following bar removal.
