Reoperations after total correction of fallot

İstanbul Göğüs Kalp ve Damar Cerrahisi Merkezi'nde 1963-1989 yılları arasında fallot tetralojisi nedeniyle total korreksiyon yapılan ve hastane mortalitesi dışında kalan olgu sayısı 273'tür. Bu olgulardan 5 tanesi reopere edilmiştir (% 1.83 ). Reoperasyon nedeni 3 olguda rezidüel ventriküler septal defect, bir olguda rezidüel VSD ve transannuler perikard yama anevrizması, bir olguda ise triküspid kapak endokarditine bağlı triküspid yetmezliği olmuştur. Reoperasyonlarda 2 olguda VSD yama ile tamir edilmiş, bir olguda ilave olarak triküspide Dewega annuloplasti yapılmış, bir olguda VSD kapatılması ve anevrizmektomi uygulanmış, bir olguda ise triküspid kapak replasmanı yapılmıştır. Ameliyat sonu dönemde bir olguda uzamış mekanik ventilasyon, bir olguda A-V tam blok nedeniyle kalıcı pacemaker implantasyonu gerekmiştir. Hasta mortalitesi yoktur.In İstanbul thoracic and cardiovascular surgery centre, between the years of 1963-1989, 273 case had total correction because of fallot tetralogy and these were exceptional according to the mortality ranges of the hospital 5 out of these operation were reoperated (% 1.83). The reasons of the reoperations were: residual VSD in three cases, residual VSD and transannular pericardial patch aneurysm together in one case and tricuspid failure due to tricuspid valve endocarditis in one case. In repeating operations, VSD was repaired by a patch in two of them and in one of them tricuspid devega annuloplasty was perfomıed additionally and one of them tricuspid valve replacement was achieved. In the postoperative stage, prolonged mechanical ventilation in one of them and permanent pacemaker implantation due to AV complete block in arıother were reeded. There was not mortality

Pacemaker Lead Endocarditis: Report of Two Cases

Pacemaker lead endocarditis was diagnosed in two different patients. Causative microorganism was Staphylococus aureus and Staphylococcus epidermidis in the first and the second patient respectively. Patients were treated with antibiotics including cefazoline 3 x 2 g intravenous (IV) plus gentamicin 3 x 1 mg/kg IV and rifampicin 3 x 300 mg oral, for 8 weeks and with the surgical removal of lead system. Clinical aspects, treatment options and diagnostic criteria of pacemaker lead endocarditis were discussed

Comparative effects of tolazoline and nitroprusside on human isolated radial artery

Background. The radial artery is increasingly being used in coronary revascularization as an alternative conduit to a saphenous vein graft. Its perfect endothelial capacity provides a high patency rate comparable with the internal mammary artery (IMA). However, its spastic characteristics cause difficulties during its intraoperative preparation and may lead to early postoperative graft failure. Thus, treatment and/or prevention of radial artery spasm with an effective vasodilator agent is essential for its longevity. Endogenous vasoconstrictors, including noradrenaline, endothelin-1, and thromboxane A, are likely to play a role in the pathogenesis of graft spasm. In the present study, we evaluated the vasorelaxant effect of tolazoline, a nonselective alpha-adrenoceptor blocker, against the contractions induced by various spasmogenic agents in an isolated human radial artery

Campylobacter anatolicus sp. nov., a novel member of the genus Campylobacter isolated from feces of Anatolian Ground Squirrel (Spermophilus xanthoprymnus) in Turkey

Seventy-four Gram-negative, motile, slightly curved rod-shaped, microaerophilic, oxidase-positive and catalase-negative isolates, recovered from fecal samples of the Anatolian ground squirrel (Spermophilus xanthoprymnus) in Kayseri, Turkey, were subjected to a polyphasic taxonomic study. Results of a genus-specific PCR indicated that all isolates belonged to the genus Campylobacter. 16S rRNA gene sequence analyses revealed the closest match as Campylobacter curvus DSM 6644(T) with identity levels of 96.41-96.70%. Based on the 16S rRNA gene phylogeny of the 74 isolates, six isolates (faydin-G24, faydin-G52, faydin-G105, faydin-G114, faydin-G129 and faydin-G140(T)) were chosen as representatives for further characterization. The overall genome relatedness indices for the strain faydin-G140(T), compared to the most closely related type strain C. curvus ATCC 35224(T), were calculated as 15.2%, 72.5%, and 83.7% for digital DNA-DNA hybridization (dDDH), and average nucleotide identity (ANIb and ANIm), respectively. The G+C content and genome size of the strains ranged between 35.2-35.4 mol% and 1.7-1.8 Mb, respectively. Based on data obtained from the polyphasic taxonomy approach, including phenotypic characterization as well as genomic and chemotaxonomic analyses, these strains are concluded to represent a novel species, for which the name Campylobacter anatolicus sp. nov. is proposed with faydin-G140(T) as the type strain (=DSM 112311(T) = LMG 32238(T)) (C) 2021 Elsevier GmbH.
