Hybrid Surgery for Intralobar Pulmonary Sequestration With Aortic Aneurysm

Isolated endovascular repair of anomalous systemic arterial supply to the left basal lung

“…Based on previous literature, treatment options are as follows: simultaneous division or ligation of the aberrant feeding artery and segmental lobectomy; isolated treatment of the aberrant feeding artery, including surgical ligations or division under thoracotomy or Video-Assisted Thoracoscopic Surgery (VATS); endovascular procedures, such as coil or plug embolization to the aberrant feeding artery or TEVAR to occlude it; and, unifocalized anastomosis between the aberrant feeding artery and the pulmonary artery. The outcomes of both J o u r n a l P r e -p r o o f surgical repair and endovascular treatments for aberrant aneurysm with PS were good without major complications [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In these reports, surgical lobectomy was performed in 8 cases; TEVAR and secondary lobectomy was chosen in cases.…”

Embolization was performed in two cases, one of which was by TEVAR.…”

Intralobar pulmonary sequestration: incidental finding in an asymptomatic patient

“…In comparison with an open thoracotomy, VATS is associated with less intraoperative bleeding and shorter postoperative hospital stays [15] . Alternative management options include endovascular embolization and coiling in cases where open thoracotomy is likely to cause high levels of morbidity and mortality [16 , 17] or hybrid thoracic endovascular aortic repair-lobectomy treatment for cases of intralobar PS involving an aneurismal feeding vessel [18 , 19] .…”

Retrospective review of the diagnosis and treatment of pulmonary sequestration in 28 patients: surgery or endovascular techniques?

“…In our study, 3 cases of PS have aneurysmal dilation and 1 case of PS has aortic dissection at the initial part of feeding artery. Although the etiology of the aneurysmal dilation and aortic dissection is uncertain, we and others suspect it may be due to systemic arterial high-pressure flow in the sequestered lung (17,18). Low wall shear stress occurs at arterial bifurcations, branch ostia, and curvatures, with aneurysm growth occurring at these low shear stress regions (19).…”

“…Fragile blood vessels were observed in PS patients, possibly due to inflammation, atherosclerosis, and even aneurysms. Very few reports have been published describing aortic aneurysmal dilatation at the origin of the aberrant systemic artery (17,18). Surgical resection is applied to patients under urgent or semi-urgent circumstances like a possible rupture during the treatment of PS.…”
