Coronavirus disease 2019 (COVID-19) pandemic caused infection in a season when influenza is still prevalent. Both viruses have similar transmission characteristics and common clinical manifestations. Influenza has been described to cause respiratory infection with some other respiratory pathogens. However, the information of COVID-19 and influenza coinfection is limited. In this study, we reported our coinfected cases and reviewed the literature. We included all COVID-19 diagnosed patients. All patients with a presumed diagnosis of COVID-19 were routinely screened for influenza. Their thorax radiology was reviewed for COVID-19-influenza differentiation. During the study period, 1103 patients have been diagnosed with COVID-19. Among them, six patients (0.54%) were diagnosed coinfected with influenza. There have been 28 more coinfected patients reported. Laboratory-based

Bu çalışmada akut tip A aort diseksiyonlu hastalarda rezidüel sahte lümeni çıkarmak ve geç dönem komplikasyonları önlemek için kullandığımız E-vita OPEN PLUS stent grefti ile total torasik aort onarımının erken ve orta dönem sonuçları araştırıldı.Ça lış ma pla nı: Çalışmaya Kasım 2013 -Kasım 2017 tarihleri arasında akut tip A aort diseksiyonu nedeniyle frozen elephant trunk stent grefti ile total torasik aort onarımı geçiren 41 hasta (29 erkek, 12 kadın; ort. yaş 51.9±10.4 yıl; dağılım, 30-77 yıl) dahil edildi. Sahte lümen boyutundaki azalma ve tromboz 10. günde ve üçüncü, altıncı ve 12. aylarda tekrarlanan bilgisayarlı tomografi-anjiyografi ile değerlendirildi.Bul gu lar: Altı hasta (%14.6) hastanede kalış süresinde ve bir hasta (%2.4) takip süresinde kaybedildi. Frozen elephant trunk stent greftin distal ucu inen aortta T 6 , T 7 ve T 8 düzeylerinde sırasıyla 15 (%36.6), 21 (%51.2) ve beş (%12.2) hastada sonlandı. Supra-aortik damarlar 21 hastada (%51.2) ayrı şekilde veya 20 hastada (%48.8) adacık olarak yeniden implante edildi. Geçici paraparezi (spinal kord iskemisi) sadece bir hastada (%(2.4) gözlenirken iki hastada (%4.9) kalıcı nörolojik defisit (inme veya koma) gözlendi. Ortalama takip süresi 26.5±20.5 ay idi. Birinci aydaki bilgisayarlı tomografi-anjiyografi sahte lümenin pulmoner gövde ve diyafragmatik düzeyde sırasıyla %93.9 ve %54.5 oranında tromboze olduğunu gösterdi. So nuç:Erken dönem sahte lümen trombozunu sağlayarak tek aşamalı frozen elephant trunk tekniği ile akut tip A aort diseksiyonu tedavisinde total arkus onarımının güvenli ve başarılı olduğunu düşünüyoruz.

Introduction The aim of this study is to compare postoperative outcomes and follow-up of two different modifications facilitating surgical technique of frozen elephant trunk (FET) procedure for complex thoracic aortic diseases - zone 0 (fixation with total arch debranching) and zone 3 (fixation with islet-shape arch repair). Methods From May 2012 to December 2018, data were collected from 139 patients who had been treated with FET procedure for complex thoracic aortic diseases. According to Ishimaru arch map, patients with proximal anastomotic site of hybrid graft at zone 0 and zone 3 were grouped as Group A (n=58, 41.7%) and Group B (n=81, 58.3%), respectively. Mean age of study population was 54.7±11.4 years, and 111 patients were male (79.9%). Results In-hospital mortality was observed in 20 (14.4%) patients (n=12, acute type A aortic dissection, and n=4, previous aortic dissection surgery). There was no significant difference between both groups in terms of in-hospital mortality. Four patients from Group A and three patients from Group B had permanent neurological deficit ( P =0.32). Three patients from both groups had transient spinal cord ischemia ( P =0.334). Although mean total perfusion time was longer in Group A, duration of visceral ischemia, when compared with Group B, was shorter ( P <0.001). Five-year survival rate was 82.8% in Group A and 81.5% in Group B ( P =0.876). Conclusion FET procedure is a feasible repair technique in the treatment of complex aortic diseases, providing satisfactory early results. Because of its advantageous aspects, zone 0 fixation with debranching is the preferred technique in our clinic.
