Segmentectomy of the Left Lower Lobe

Chapter
The segmental vessels, particularly the segmental vein vary more in the lower than in the upper lobe. However, unlike the upper lobe, the segmental vein does not need to be identified for segmentectomy of the lower lobe, in which the segmental arteries are identified and cut first, followed by cutting the segmental bronchus. Next, the segmental veins running towards the segment scheduled for resection are cut, which does not require their identification. Instead, the segmental arteries should be identified accurately from both MDCT and intraoperative findings during segmentectomy of the lower lobe. Like this, anatomical segmentectomy of a lower lobe depends on precise identification of the segmental arteries.
