“…Variable findings have also been reported in studies of radiological images. It is difficult to assess the completeness of lung fissures on chest radiographs, as only the RHF can be reliably observed (Suwatanapongched et al, 2015). The rates of incompleteness of the main fissures reported in a CT series of 387 patients, found the ROF, RHF and LOF to be incomplete in 69.7%, 86.9% and 48.3% of cases, respectively (Ozmen, Nazaroglu, Bayrak, Senturk, & Akay, 2010).…”

Introduction The lungs have three main fissures: the right oblique fissure (ROF), right horizontal fissure (RHF), and left oblique fissure (LOF). These can be complete, incomplete or absent; quantifying the degree of completeness of these fissures is novel. Standard textbooks often refer to the fissures as complete, but awareness of variation is essential in thoracic surgery. Materials and Methods Fissures in 81 pairs of cadaveric lungs were classified. Oblique fissures were measured from lung hila posteriorly to the lung hila anteriorly; and the RHF measured from the ROF to the anteromedial lung edge. The degree of completeness of fissures was expressed as a percentage of the total projected length were they to be complete. The frequency and location of accessory fissures was noted. Results LOF were complete in 66/81 (81.5%), incomplete in 13/81 (16.0%) and absent in 2/81 (2.47%); ROF were complete in 52/81 (64.2%), incomplete in 29/81 (35.8%) and never absent; RHF were more variable, complete in 18/81 (22.2%), incomplete in 54/81 (66.7%) and absent in 9/81 (11.1%). LOF and ROF were on average 97.1% and 91.6% complete, respectively, being deficient posteriorly at the lung hila. The RHF on average 69.4% complete, being deficient anteromedially. There were accessory fissures in 10 left and 19 right lungs. Conclusions This study provides a projection of the anatomy thoracic surgeons may encounter at operation, in particular the variable RHF. This knowledge is essential for optimal outcomes in both benign and oncological procedures influenced by the fissures.

“…Por lo tanto, hay que esperar variaciones anatómicas al disecar o inspeccionar muestras. 4,5 El estudio de los pulmones por tomografía axial computarizada se ha extendido ampliamente y las pequeñas lesiones pulmonares son detectadas a través de este método, en particular la incidencia del carcinoma de células pulmonares cada vez más pequeñas y las no pequeñas que pueden tener un comportamiento biológico más indolente tal como el carcinoma broncoalveolar se ha incrementado cada vez más. 6 8 Saladrigas-Sarduy, Sirian y col.…”

Contexto: El cáncer de pulmón es la enfermedad causante de la mayor mortalidad por neoplasias malignas, tanto a escala mundial como en Cuba, por lo que el conocimiento de las complejas variaciones anatómicas y un acertado conocimiento de la anatomía individual se ha convertido en algo cada más importante para los cirujanos torácicos generales al ejecutar una cirugía precisa y segura. Objetivo: Describir las principales variantes anatómicas en bronquios y arterias segmentarias en pulmones humanos. Metodología: Se realizó un estudio descriptivo y transversal en 50 bloques de pulmones humanos obtenidos mediante necropsia del departamento de Medicina Legal del Hospital Docente Clínico Quirúrgico Amalia Simoni de Camagüey. Resultados: se observaron las variantes en los bronquios segmentarios según el número, predominaron los bronquios supernumerarios B1, B2 y B3 en ambos pulmones. La mayor parte de las piezas presentó arterias segmentarias supernumerarias en ambos pulmones A1, A2, A3 y A6. Las variantes en el origen tanto en bronquios como en arterias fueron raras. Conclusiones: Las variantes de número predominaron respecto a las de origen, se observaron con mayor frecuencia en los lóbulos superiores de ambos pulmones y predominó la duplicidad.
