Endovascular Repair of Ruptured Aberrant Left Subclavian Artery With Right Aortic Arch

Single-Stage Surgical Repair of Kommerell Diverticulum with Annuloaortic Ectasia via a Median Sternotomy: Frozen Elephant Trunk Technique with an Antler-Like Shape Reconstruction of Arch Branches

“…Various methods of repair have been described, such as open surgical repair via thoracotomy or sternotomy, or endovascular repair. 1 – 6 ) In their study, Motoki et al 4 ) reported endovascular repair of a ruptured KD, concluding that this endovascular repair is a valuable alternative approach for ruptured KD. However, they pointed out that it is difficult to deliver the stent grafts through the aortic arch because of the severe angulation of the aortic arch.…”

Random Finding of a Ruptured Kommerell Aneurysm After Stroke

“…By contrast, TEVAR is gaining increasing importance in the management of KA. It has been shown to be a feasible and safe alternative to open repair [1][2][3][4][5]. In our case, to obtain proximal sealing, the stent-graft had to be landed at the origin of the bicarotid trunk, covering both the LSA and the aberrant RSA ostia.…”

“…Whereas a retroesophageal right subclavian artery (RSA) is not as rare, rupture of a KA (rKA) is an exceptional event. Over the past decade, various hybrid techniques for the treatment of KA have been described [1][2][3][4][5], inasmuch as alternatives to conventional open repair involving left heart bypass or deep hypothermic circulatory arrest. Endovascular techniques might significantly reduce perioperative morbidity and mortality.…”

Kommerell Diverticulum Should Be Removed in Children With Vascular Ring and Aberrant Left Subclavian Artery

“…Typical symptoms such as effort dyspnea, stridor, chronic cough, and dysphagia were present in 92% of our patients, and most of these patients were infants. Late diagnosis in adulthood is often the result of early atherosclerotic changes of the anomalous vessel, with aneurysm formation, dissection, and even rupture that may be fatal [2][3][4][5]. In addition, patients in whom a "simple" ligamentum division was performed may present with residual symptoms related to the dilated diverticulum [2,7].…”

“…It is clearly larger than the subsequent artery because it is the segment connected, in case of a right aortic arch, to the left ductus arteriosus and the LSCA and because the fetal ductus arteriosus carries a large volume of blood [1][2][3]. An extremely dilated diverticulum may contribute to the compression symptoms (decreasing the space in the ring) but may also cause complications such as rupture or dissection of the aorta during adulthood [4,5].…”
