Abstract

Introduction: There are many anatomical variations in the bronchial distribution of the lower left lung lobe. The control of its variations offers a better guarantee for safe and controlled removal surgery. The objective of this work was to study the bronchial distribution of the lower left lung lobe, to specify its variations and their surgical implications.

Methods: Thus, we operated 17 broncho-arterial moldings made from heart-lung blocks treated by injection-corrosion.

Results: Our results were as follows: the lower lobar bronchus was present in 100% of cases and measured 0.65 cm on average. It ended by giving the apical and basal bronchi. The apical bronchus ended in 64.70% of cases with a bifurcation and in 35.30% with a trifurcation. As for the basal bronchus, it is 1.1 cm long. It gave successively the ventro-paracardiac trunk (TVPC) which bifurcated in 88.23% of cases in baso-medial and baso-ventral bronchi; the baso-lateral bronchus which was typical in 58,82% of cases; and ended with the baso-terminal bronchus in our cases.

Conclusion: This distribution presents many variations which must be taken into account for a quality excision.
