Amaç: Çalışmamızın amacı, çeşitli ön tanılar için çok dedektörlü bilgisayarlı tomografi (ÇDBT) anjiyografisi uygulanan hastalarda çölyak arter, superior mezenterik arter (SMA), inferior mezenterik arter (İMA), renal arterler (RA) ve hepatik arterlerde (HA) varyasyonları belirlemektir. Gereç ve Yöntemler: Bu çalışmada, ÇDBT anjiyografisi yapılan 200 hasta retrospektif olarak analiz edilmiştir. Çölyak trunkus varyantları için Uflacker sınıflandırması, HA varyasyonları için Michels ve Hiatt sınıflandırmaları kullanılmış ve RA'lar, sayı ve ekstra-RA varlığı açısından değerlendirilmiş, replase veya aksesuar RA'lar sayısal anomaliler olarak sınıflandırılmıştır. Bulgular: Hastaların %92,0'sinde klasik çölyak trunkus mevcuttu ve varyasyonlar arasında hepatosplenik ve gastrosplenik trunkuslar her biri %3,5 oranında görüldü. Çölyak trunkusun klasik dallanma deseni hastaların %91,5'inde saptanırken, %1,0'inde sol gastrik arterin splenik arterden veya doğrudan abdominal aortadan kaynaklandığı görüldü. SMA orijini vakaların %95,5'inde klasik olup, %2,5'inde hepatomezenterik trunkus orijini ve %1,0'inde bimesenterik trunkus orijini vardı. İMA için, hastaların %98,4'ünde klasik bir orijin mevcuttu. Sağ RA sayısı 2 veya daha fazla olanların oranı %13 iken, sol RA sayısı 2 veya daha fazla olanların oranı %12,5 idi. Sağ HA varyasyonları hastaların %14,5'inde gözlenirken, sol HA varyasyonları %11,5 oranında mevcut idi. Sonuçlar: Çalışmamız, MSBT yapılan hastalarda çölyak arterlerde, SMA’da, RA’da ve HA’da önemli anatomik varyasyonlar olduğunu ortaya koymuştur. Bulgular, doğru tanı ve cerrahi planlama için bu varyasyonların tanınmasının önemini vurgulamaktadır.

Aim: Lumbosakral transitional vertebrae (LSTV) are anatomical variations where a vertebra exhibits characteristics of both lumbar and sacral vertebrae. This study aims to assess anatomical changes in LSTV patients by measuring intervertebral disc height (IVDh), vertebral foramen anteroposterior diameter (FVAPd), and intervertebral foramen height (FIVh), with consideration of age and gender differences. Material and Methods: This retrospective study included 274 patients diagnosed with LSTV. All MRI images were acquired with a 1.5T MRI machine and a 32-channel lumbar coil. The presence of LSTV, forming the morphological data, was identified from coronal and sagittal reformat images and was classified as either lumbarization or sacralization. Morphometric data (IVDh, FIVh and FVAPd) were acquired from axial, sagittal, and coronal planes using both soft tissue and bone window settings. Results: The mean patient age was 41.6±13.0 years, with a female majority (55.8%). LSTV was predominantly lumbarization (96.4%), with sacralization in the remaining cases. The overall mean FVAPd was 11.2±2.4 mm, mean IVDh was 9.1±1.8 mm, and mean FIVh was 18.8±2.4 mm on the right and 19.1±2.4 mm on the left. IVDh levels were consistent across age groups, while FVAPd values were similar between genders. Patients aged 40 and under had higher FVAPd and FIVh levels, and male patients had higher IVDh and FIVh levels compared to females. Conclusions: The morphometric characteristics of LSTV may vary according to age and gender. Considering these factors in accurately identifying the anatomical variations of LSTV may play a significant role in determining appropriate treatment and management strategies.

Aim: Although several research have been undertaken to investigate the impact of the vaccination on long Coronavirus Disease 2019 (COVID-19) syndrome or post-acute sequelae, there is a lack of published evidence on the long-term effects of vaccines on lung-sequelae-related disease. Considering the limited global COVID-19 vaccine distribution, it is essential to establish the impact of vaccination in reducing pulmonary complications. Turkey has been offering COVID-19 vaccines from two platforms, including BNT162b2 (Pfizer-BioNTech, mRNA vaccine) and CoronaVac (Sinovac, inactivated vaccine). This study aimed to evaluate the efficacy of BioNTech and Sinovac vaccines in reducing post-COVID-19 pulmonary complications in individuals. Material and Methods: A total of 94 patients COVID-19 pneumonia patients who were categorized based on the quantity of BioNTech or Sinovac vaccines they received before their first COVID-19 infection were included. The inclusion criteria consisted of a confirmed diagnosis of COVID-19 pneumonia through polymerase chain reaction testing, availability of the mentioned before and follow-up computed tomography scans, and administration of at least one dose of vaccine. Results: The number of complications in patients fully vaccinated with Sinovac and who experienced post-COVID lung complications was significantly greater than in those vaccinated with BioNTech. The C-reactive protein and D-Dimer measurements of individuals who experienced complications in the Sinovac vaccinated group were significantly elevated on the index date. Conclusion: The quantity of lung sequelae after COVID and laboratory parameters indicating this result were found to be higher in inactivated virus vaccines than in mRNA vaccines. This suggests that the protection of inactivated vaccines may be insufficient in severe cases.
