Abstract

Objective: Lung fissures embryologically separate the bronchopulmonary segments from each other. We aimed to detect anatomical variations in fissures in patients who underwent thoracic computed tomography (CT).
Materials and Methods: All the patients underwent a thoracic CT examination between July 1 - July 15, 2022. The patients’ gender, lung fissures continuity, accessory fissures presence, and variation side were recorded. The frequency of fissures was compared between the genders using the chi-square test.
Results: The study included a total of 352 patients (211 men, 141 women). A total of 105 variations were detected in 95/352 (26.99%) of the patients, 61/211 (28.91%) were male, 34/141 (24.11%) were female. The right oblique fissure was incomplete in nine (2.6%), and the right horizontal fissure was incomplete in 14 (4%) patients and absent in 14 (4%). The left oblique fissure was observed to be incomplete in 16 (4.5%) patients. A total of 52 (14.8%) accessory fissures were detected.
Conclusion: In the literature, a wide variety of fissure variations have been reported. Due to this diversity, having good knowledge of the fissure anatomical architecture is essential when performing surgical procedures and interpreting radiological images to clinically identify the location of bronchopulmonary segments.

Bilgisayarlı Tomografide Akciğer Fissüründeki Anatomik Varyasyonlar

Abstract

Amaç: Akciğer fissürleri embriyolojik olarak bronkopulmoner segmentleri birbirinden ayırırlar. Bu nedenle biz de toraks bilgisayarlı tomografi (BT) çekilen hastalarda fissürlerdeki anatomik varyasyonları bulmayı amaçladık.
Materyal ve Metod: Çalışmamıza 01 -15 Temmuz 2022 tarihleri arasında toraks BT tetkiki çektiren tüm hastalar dahil edilmiştir. Hastaların cinsiyetleri, akciğer fissürlerinin devamlılık durumu, aksesuar fissür varlığı ve varyasyonun tarafı kaydedildi. Cinsiyetler arası fissür sıklığı ki-kare testi kullanılarak değerlendirilmiştir.
Bulgular: Çalışmamıza toplamda 352 hasta (211 erkek, 141 kadın) dahil edildi. hastaların 95/352 (%26,99) tanesinde 105 varyasyon tespit edildi bunların 61/211’i (%28,91) erkek, 34/141’i (%24,11) kadındı. Sağ oblik fissür dokuz (%2,6) hastada inkomplet; sağ horizontal fissür 14 (%4) hastada inkomplet, 14 (%4) hastada ise yoktu. Sol oblik fissür 16 (%4,5) hastada inkomplet olarak izlendi. Toplamda 52 (%14,8) aksesuar fissür tespit edildi.
Sonuç: Literatürde çeşitli fissür varyasyon sıklığı bildirilmiştir. Bu çeşitlilik nedeniyle, cerrahi işlemler yapılırken ve radyolojik görüntüleri klinik olarak yorumlarken bronkopulmoner segmentlerin yerini tespit etmek için fissür anatomik yapısını iyi bilmek önemlidir.
