Correlation Between The Amount Of Pericardial Fat And Cardiophrenic Sinus Blunting

Amaç: Bu çalışmada kalp çevresindeki visseral yağ dokusunun, kardiyofrenik sinüste silinmeye neden olması içingerekli hacmi ve komşuluğunda izlenen atelektazi ile arasındaki ilişkiyi araştırmayı amaçladık. Yöntem ve Gereçler: Herhangi bir nedenle Toraks BT çekimi yapılan 180 hasta çalışma grubuna alındı. Her kesittekalp çevresindeki yağ dokusu sınırları çizilerek, üç boyutlu reformat görüntülerde yağ dokusu hacmi yarı-otomatikolarak hesaplandı Parakardiyak visseral yağ dokusu hacmi ve kalınlığı ile VKİ, kardiyofrenik sinüsteki silinme vekompresyon atelektazi arasındaki ilişki SPSS 16.0 hazır programı kullanılarak ANOVA ve ki-kare testleri ile değer- lendirildi Bulgular: Hastaların ölçülen toplam parakardiyak visseral yağ dokusu hacimleri VKİ grupları ile iyi korelasyongöstermekteydi. Ayrıca her iki tarafta parakardiyak visseral yağ dokusu hacmi ve kalınlığı ile komşuluğunda izlenenkompresyon atelektazisi ve bilateral kardiyofrenik sinüsteki küntleşme arasında anlamlı ilişki tespit edildi.Sonuç: Akciğer grafisinde kardiyofrenik sinüslerde küntleşme görüldüğünde parakardiyak visseral yağ dokusu ar- tışının bu görünüme sebep olabileceği göz önünde bulundurulmalıdır. Bu olgularda bazallerde izlenen parankimaldansite artışlarında enflamasyon ya da kitle gibi lezyonlardan önce atelektazi düşünülmelidir.

Kalp Çevresindeki Visseral Yağ Dokusunun Kardiyofrenik Sinüslerdeki Silinme ile İlişkisi

Aim: In this study we aimed to investigate the volume of the paracardiac visceral fat tissue that was necessary tocause blunting of the sinus and its' relation with adjacent compression atelectasies. Material and Methods: We assessed 180 thorax CT scans regardless of the indication. In each patient, margins ofparacardiac fat tissue were drawn in 3-D reformatted images and the volume of fat tissue was calculated semi-auto- matically and recorded. The relation between paracardiac visseral fat tissue volume and thickness, BMI, blunting ofthe cardiophrenic sinus and compression atelectasis were evaluated with ANOVA and chi- square tests using SPSSpackage program version 16.0.Results: Overall paracardiac fat tissue volume measured correlated well with their BMI groups. In addition, signifi- cant relation was found between the thickness and volume of paracardiac fat tissue and adjacent compresion atelec- tasis and blunting in bilateral cardiophrenic sinus observed on both sides.Conclusions: Cardiophrenic sinus blunting in both lungs observed in chest X-Ray, might be related to the compres- sion due to increased amount of paracardiac fat tissue. In these cases, atelectasis should be considered before inflam- mation or mass lesions when increase in parenchyme density is observed.
