left pul·mo·nar·y ar·ter·y

[TA]
the shorter of the two terminal branches of the pulmonary trunk, it pierces the pericardium to enter the hilum of the left lung. Branches ramify and are distributed with the segmental and subsegmental bronchi; frequent variations occur. Typical branches: of the superior lobar arteries [TA] (arteriae lobares superiores pulmonis , under arteria [TA]) are the apical segmental artery [TA] (arteria segmentalis apicalis (dextri et sinistri) [TA]), anterior segmental artery [TA] (arteria segmentalis anterior pulmonis (dextri et sinistri) [TA]), and posterior segmental artery [TA] (arteria segmentalis posterior pulmonis (dextri et sinistri) [TA]), with the latter two having ascending and descending branches [TA] (rami ascendens et descendens [TA]); of the lingular artery [TA] (arteria lingularis [TA]) are the superior lingular artery [TA] (arteria lingularis superior [TA]) and inferior lingular artery [TA] (arteria lingularis inferior [TA]); and of the inferior lobar arteries [TA] (arteriae lobares inferiores pulmonis , under arteria [TA]) are the superior segmental artery [TA] (arteria segmentalis superior pulmonis (dextri et sinistri) [TA]) and a basal part [TA] (pars basalis [TA]) giving rise to anterior, posterior, lateral, and medial basal segmental arteries [TA] (arteriae segmentales basales anterior, posterior, lateralis et medialis [TA]).

left pul·mo·nar·y ar·te·ry

(left pul'mŏ-nar-ē ahr'tĕr-ē) [TA]
The shorter of the two terminal branches of the pulmonary trunk, it pierces the pericardium to enter the hilum of the left lung. Its branches accompany the segmental and subsegmental bronchi. Branches to the superior lobe (rami lobi superioris [TA]) are apical (ramus apicalis [TA]), anterior ascending (ramus anterior ascendens [TA]), anterior descending (ramus anterior descendens [TA]), posterior (ramus posterior [TA]), and lingular (ramus lingularis [TA]), the last having inferior and superior branches (rami lingulares inferior et superior [TA]). Branches to the inferior lobe (rami lobi inferioris [TA]) are the superior branch of the inferior lobe (ramus superior lobi inferioris [TA]) and the medial (medialis), anterior, lateral (lateralis), and posterior basal branches (rami basales [TA]).

(8) Symptomatic cases produce significant morbidity and mortality, and are usually managed by left pulmonary artery reimplantation surgery.
During the echo imaging we are able to estimate the flow in the aorta and in both pulmonary arteries in order to be sure that none of the vessels (especially the left pulmonary artery) are narrowed9.
Various authors also believe that suture technique is an important factor in preventing stenosis, with one suggesting the use of a continuous suture with every third stitch locked posteriorly and an interrupted suture anteriorly.22 Also distal conduit anastomosis is advised to be towards the left pulmonary artery as it prevents contact between the lesser curvature of the ascending aorta and distal Contegra anastomosis, which may potentially induce conduit narrowing.1,23 The valve should also be kept as distal as possible from the RV anastomosis.
Pulmonary arterial angiography indicated a disharmonious pulmonary tree with a marked dilation of left pulmonary artery (dimensions = 47/65 mm) (Figure 3).
Once satisfied with the location of the device, and with no arch narrowing and with no left pulmonary artery stenosis, the device was finally released from the delivery cable by counterclockwise rotation.
(10) Typical findings on MDCT of an uncomplicated PDA would include a tubular structure connecting the descending aorta with the distal main pulmonary artery or the proximal left pulmonary artery. Accurate measurements including narrowest and widest diameter of the PDA as well as length of the PDA can accurately and easily be done on MDCT to assist surgical management.
A digital subtraction cineangiography performed in the left pulmonary artery (LPA) showed flow only to the left upper lobe (Figure 2).
