Incidence of anomalies of the aortic arch is estimated 1-2 per cent in newborn babies. Lusory artery may arise either from left sided aortic arch in 0.7–2 per cent, or from right sided aortic arch in 0.4 per cent. Leading symptoms develop from compression of the oesophagus or trachea, or both. If lusory artery dilates conically over the time reaching 3 cm or more we call it Kommerell diverticulum. Very rare complications of this are the Type B aortic dissection, which may turn into chronic thoracoabdominal aneurysm, or its shaggy inner surface can be the source of upper extremity embolism. Rupture is extremely rare complication. In our report we focus on five cases of the mentioned complications with their clinical workups and technical solutions. In a female patient with right sided arch transection of the lusory artery was followed by transposition into the right common carotid artery. The central stump 10 years later gradually expanded and the saccular aneurysm indicated intervention. After complete arch debranching thoracic endograft was implanted. In this group of patients with variable surgical and hybrid procedures neither complication nor mortality occurred.

Introduction: Coarctation of the aorta (CoA) patients often experience recoarctation, the reoccurrence of aortic narrowing, presenting a considerable clinical challenge.

Aim: This study aims to investigate the triggers or contributing factors associated with the development of recoarctation (reCoA) following the initial repair of CoA.

Material And Methods: The retrospective cohort study includes information about 120 patients, who underwent 4 different types of surgical repairs of coarctation of the aorta through left thoracotomy in the period 2012-2022.

Objective: Giant cell arteritis (GCA) may present as proximal aortic pathology requiring surgical intervention. We present our experience with surgical management of GCA in patients presenting with proximal aortic disease.

Methods: From January 1993 to May 2020, 184 adult patients were diagnosed with GCA on histopathology after undergoing cardiac surgery.

Objective: For neonatal repair of coarctation of the aorta, patients may either undergo thoracotomy with extended end-to-end anastomosis or sternotomy for aortic arch reconstruction with cardiopulmonary bypass. The objective of this study was to evaluate the comparative effectiveness of the 2 approaches in patients with arch hypoplasia.

Methods: This is a single-center retrospective cohort study from July 2005 through May 2022 of patients who underwent neonatal repair for isolated coarctation of the aorta with additional arch hypoplasia.

Objective: The optimal method for cerebral protection during aortic arch reconstruction in neonates and infants is unknown. We compare the outcomes of deep hypothermic circulatory arrest and selective antegrade cerebral perfusion strategies in neonatal and infant cardiac surgery.

Methods: We retrospectively identified all patients aged less than 1 year who underwent aortic arch reconstruction from 2012 to 2023.

Objective: A novel approach to 3-dimensional morphometry of the thoracic aorta was developed by applying centerline analysis based on least-squares plane fitting, and a preliminary study was conducted using computed tomography imaging data.

Methods: We retrospectively compared 3 groups of patients (16 controls without aortic disease, and 16 cases each with acute type B aortic dissection and congenital bicuspid aortic valve). In addition to the standard assessment indices for curvature κ and torsion τ, we conducted coordinate transformation based on the least-squares plane, divided the centerline into 3 representative features (transverse, anterior-posterior, and longitudinal displacements), and analyzed the overall and local displacement in each direction.
