Example: "The ultrasound revealed the presence of abnormal veins, which may indicate a potential health issue."
Alternatives: "irregular veins" or "atypical veins".
a Three-dimensional image shows an abnormal vein (arrow) running over a branch of the pulmonary artery.
We decided not to preserve the middle lobe because of the risk of thrombus development in the abnormal vein and resultant systemic thromboembolism.
d After transecting the abnormal vein shown in (c) (arrowheads), the interlobar pulmonary artery behind was approached according to the 3D images.
These studies related to the abnormal vein patterning caused by mutation of particular genes provide some clue as to how Kranz anatomy is regulated and suggest involvement of multiple pathways in development of the Kranz pattern.
The subcardinal veins that are located ventrally, form anastomoses with the cardinal veins and may have been involved in the formation of the ventrally located abnormal vein in this patient.
In cases involving large abnormal draining veins, such as "meandering veins," conventional open thoracotomy or median sternotomy often is required [1, 2].
c Corresponding intraoperative view shows the exposed abnormal pulmonary vein (arrow; same vein as shown in a).
In particular, the abnormal pulmonary veins were running in disorder, penetrating multiple lobes.
Moreover, by accurately accessing the vascular anatomy and lobulation of the lung, we preoperatively decided to preserve the upper lobe while considering the risk of systemic thrombosis, which might have occurred if we had preserved the abnormal drainage veins, particularly in the middle lobe in this case.
mutant has an abnormal leaf vein pattern (VEP) (Jun et al. 2002).
