Ozet Amac. Son yillarda cerrahi tekniklerdeki onemli gelismelere ragmen, asendan aortayi tutan patolojiler ciddi mortalite ve morbidite oranlari nedeniyle onemini surdurmektedir. Calismamizda asendan aorta patolojileri nedeniyle cerrahi uygulanan olgularimizi retrospektif olarak sunmayi amacladik. Yontem. Ocak 1997-Kasim 2008 tarihleri arasinda, Cumhuriyet Universitesi Kalp ve Damar Cerrahisi klinigince; Asendan aortada anevrizma veya diseksiyon on tanisiyla opere edilen 65 olguya ait sonuclar incelenmistir. Bulgular. Opere edilen 65 olgunun cinsiyet dagilimi 44'u (%67,69) erkek, 21'i (%32,30) kadin olarak izlendi. Olgularin en genci 41 en yaslisi 82 yasinda olup ortalama yas erkeklerde 62,45, kadinlarda 64,38 seklinde izlendi. En sik hastaneye gelis sikâyeti sebebi gogus ve sirt agrisi olup ikinci siklikta ise nefes darligiydi. En sik karsilasilan predispozan faktor hipertansiyon olarak izlendi. Tum olgularda tani icin torakoabdominal bilgisayarli tomografi cekildi. Yapilan tetkikler sonucu; Olgularin 32'si (%49,23) anevrizma, 29'u (%44,61) tip I diseksiyon, 2'si (%3,07) ise tip II diseksiyon on tanilariyla operasyona alindi. Olgularin 53'unde (%81,53) arterial kanul femoral artere kondu. Olgularin 6'sinda (%9,23) aksillar arter ve 4'unde (%6,15) brakial arter kanulasyon icin kullanildi. Benthall proseduru, 19(%29,23) olguya uygulandi. suprakoroner tubuler greft 27(%41,53) olguya, suprakoroner greft ve aort kapak replasmani 6(%9,23) olguya, bir olguda ise aort kapagina replasman ve anevrizmaya plikasyon, 3 (%4,6) olguda cikan aort replasmani ve aort kapak resuspansiyonu, bir olguda cikan aort replasmani ve trunkus brakiosefalikusa greft interpozisyonu uygulandi. Perioperatif donemde 65 olgudan 5(%7,69)'i kaybedildi. Izlem suresi ortalama 17,8±9,7 ay olup izlem suresince ek mortalite izlenmedi. Sonuc. Asendan aort patolojilerinde erken tani konulmasi, hizli ve uygun cerrahi prosedur secilmesi, postoperatif yeterli sure ve uygun medikasyonla takip edilmesinin morbidite ve mortaliteyi dusurecegi, uzun sureli survey de artis saglayacagi inancindayiz.

Despite significant improvements in surgical techniques, in recent years, importance of serious mortality and morbidity rates is maintaining that due to pathology of ascending aorta. In our study, we aimed to provide that our surgical application due to pathology of ascending aorta retrospectively. Methods. Between January 1997 and November 2008 65 cases were examined that diagnosed and treated by Cumhuriyet University Cardio-Vascular Surgery department in terms of aneurysm or dissection of ascending aorta. Results. Forty four (67.69%) of the cases were man and 21 (32.30%) of the cases were woman. Age ranging between 41 to 82 and main age was 62.45 in men and 64.38 in women. The most common complaint was chest and back pain and shortness of breath was the second in frequency. The most frequently encountered predisposing factor was hypertension. All cases were diagnosed with thoraco-abdominal computed tomography. In a result of examination: 32 of the cases (49.23%) were operated for aneurysm, 29 (44.61%) of the cases were operated for type I dissection and 2 (% 3.07) of the cases were operated for type II dissection. The arterial cannula was placed to femoral artery in 53 (81.53%) of the cases. In 6 (9.23%) of the cases, axillary artery was used for cannulation and in 4 (6.15%) of the cases, brachial artery was used for cannulation. Benthall procedure were applied 19 (29.23%) of the cases. Supracoronary tubular graft was applied to 27 (41.53%) of the cases; Supracoronary graft and aortic valve replacement were applied to 6 (9.23%) of the cases; Aneurysmal plication and aortic valve replacement were applied to one of the cases; Aortic valve resuspension and ascending aortic replacement were applied to 3 (%4.6) of the cases; Graft interposition to truncus brachiocephalicus and ascending aortic replacement were applied to one of the cases. 5 (% 7.69) of 65 cases were died in perioperative period. Average fallow-up period was 17.8±9.7 months and during the follow-up there is no additional mortality. Conclusion. We believe that early diagnosing, selecting of quick and appropriate surgical procedure, appropriate medical application and sufficient postoperative follow-up of ascending aortic pathologies will reduce morbidity and mortality and will also provide an increase in long-term survey.
