Anomalous Systemic Arterial Supply to Normal Basal Segment of the Left Lung

Thoracic surgery Anatomic variations of pulmonary vessels relevant with regard to lung tissue resections – literature review and personal experiences

“…The anatomic variations of the arterial system described in surgical reports in the order of frequency. The number of observed cases is provided in brackets Two separate A2R branches [17] Two arteries running to the middle lobe [8] Two arteries running to the lingular segments (4L and 5L) [5] Common branching point for A2R and A6R [4] Two A6L branches [4] Separate branching point for A1R and A3R [3] Common A1+A2+A3 trunk from the right pulmonary artery [3] Three branches to segment 2R [2] Branch A6R from the A4+A5 trunk [1] Additional A3R branch branching off in the fissure [1] Branch A7R from the A4+A5 trunk [1] Separate A1R branch and A2+A3R trunk [1] Common trunk A1+A2+A3 from the left pulmonary artery [1] Four branches running to segments 1,2,3L [1] Very low branching point of A2L [1] The short trunk running to the lingula divided into 3 branches [1] Very low branching point of the trunk running to the lingula [1] Right common arterial trunk divided into 3 branches [1] THORACIC SURGERY the competence and experience of the surgeon. Table III presents the most important variations from this group.…”

“…Direct drainage from segment 6R ( Common trunk of the right pulmonary veins [5] Common trunk of the left pulmonary veins [4] Drainage from the middle lobe emptying into the inferior pulmonary vein [3] Drainage from the middle lobe emptying into both the superior and the inferior pulmonary veins [2] Separate atrial orifice of the vein draining the middle lobe [2] Separate atrial orifice of V6R [1] Two separate veins running from the middle lobe to the right pulmonary vein [1] Separate atrial orifice of the lingular vein [1] Drainage from the lingula emptying into the inferior pulmonary vein [1] Anatomic variations of pulmonary vessels relevant with regard to lung tissue resections vessels are frequently observed to branch off, respectively, proximally and distally to the lingular branches [2,4]. Less common variations, regarding the location where the pulmonary arteries branch off from the systemic circulation, are reported as occurring primarily in the pediatric population and are frequently accompanied by congenital heart defects [5,6].…”

Successful endovascular coil embolization in an elder and asymptomatic case of anomalous systemic arterial supply to the normal basal segment

“…Furthermore, intravascular embolization with a coil was reported [7]. Transcatheter arterial embolisation was reported to prove effective therapeutic approaches in young infants without a need for surgical lobectomy [8] and to be a minimally invasive, safe, and valuable method in anomalous systemic arterial supply to the basal segment of the lung [9].…”

Computed Tomography Imaging in Patients with Congenital Heart Disease Part I: Rationale and Utility. An Expert Consensus Document of the Society of Cardiovascular Computed Tomography (SCCT)

“…170 This lesion can be asymptomatic into adulthood. [171][172][173][174] Abnormal arterial supply to the lung segments such as seen in scimitar syndrome with sequestration is also well seen by cardiovascular CT. [175][176][177][178] Cardiovascular CT is the imaging modality of choice to determine anatomic substrate and interventional planning for complex lung lesions such as intralobar or extralobar pulmonary sequestration. 179,180 In a study evaluating the utility of cardiovascular CT for surgical planning in these patients, treatments were correctly planned using cardiovascular CT with 100% accuracy, sensitivity and specificity.…”
