Vascular anatomy at the medial ends of incomplete major fissures.
Purpose of this study was to examine the relationship of the pulmonary vasculature with the medial ends of incomplete major fissures.


METHODS
All of the 2-mm thickness conventional CT and 2-mm collimated helical CT scans of the chest of the past 3 (1/2) years were reviewed. The right lungs of 132 patients and left lungs of 133 patients were examined to evaluate the pulmonary vasculature at the medial ends of the major fissures.


CONCLUSIONS
After excluding patients with complete major fissures, in 45 of 86 right lungs (52.3%) and 30 of 75 left lungs (40.0%), the pulmonary vasculature ran at the medial ends of the incomplete major fissures. In all patients, in 25.5% of conventional CT slices and 18.2% of helical CT slices of the right lungs, and in 15.1% of conventional CT slices and 11.0% of helical CT slices of the left lungs, the pulmonary vasculature was seen at the medial ends of the incomplete major fissures.
