Background: Kommerell's aneurysm is a saccular or fusiform dilatation found in 3-8% of Kommerell's diverticulum cases. A non-dissecting rupture rate of 6% has been reported. If ruptured, emergent surgical correction is usually granted. However, evidence regarding the optimal surgical approach in this acute setting is scarce. In this case report series, we aim to describe our experience managing type-1 non-dissecting ruptured Kommerell's aneurysm with hybrid emergent surgical approaches., Cases Presentation: From January 2005 to December 2020, three cases of type-1 non-dissecting ruptured Kommerell's aneurysm requiring emergent surgical repair were identified. The mean age was 66.67 ± 7.76 years, and 3/3 were male. The most common symptoms were atypical chest pain, dyspnoea, and headache (2/3). The mean aneurysm's diameter was 63.67 ± 5.69 mm. Frozen Elephant Trunk was the preferred surgical approach (2/3). The Non-Frozen Elephant Trunk patient underwent a hybrid procedure consisting of a supra-aortic debranching and a zone-2 stent-graft deployment. We found a mean clamp time of 140 ± 60.75 min, cardiac arrest time of 51.33 ± 3.06 min, and a hospital stay of 13.67 ± 5.51 days. The most common complications were surgical-site infection and shock (2/3). Only one patient died (1/3)., Conclusion: Evidence of management for non-dissecting ruptured Kommerell's aneurysms is scarce. Additional, robust, and more extensive studies are required. The selection of the appropriate surgical approach is challenging, and each patient should be individualized. Frozen Elephant Trunk was feasible for patients requiring emergent surgical repair in our centre. However, other hybrid or open procedures can be performed., (© 2023. The Author(s).)

Anomalous aortic origin of the right coronary artery is a rare disease. Although there are various reports on its treatment, the method of the surgical approach is still controversial. Here, we present a rare case of a 17 year-old man who had an anomalous aortic origin of the right coronary artery with an aberrant right subclavian artery. As a treatment, he underwent reimplantation of the right coronary artery. The surgical approach for the anomalous aortic origin of the right coronary artery should be selected by considering the age of the patient and size of the right coronary artery., (© 2022.

Introduction: Congenital single lung (CSL) is a rare condition, and symptomatic patients often present with respiratory distress or recurrent respiratory infection due to mediastinal shift causing vascular or airway compression. Aberrant right subclavian artery (ARSA) is another rare congenital anomality that can lead to tracheal or esophageal compressions. There is only one other case of concurrent presentation of CSL and ARSA reported, which presented unique challenge in surgical management of our patient. Here we present a step-wise, multidisciplinary approach to manage symptomatic CSL and ARSA., Case Presentation: An infant girl with a prenatal diagnosis of CSL developed worsening stridor and several episodes of respiratory illnesses at 11 months old. Cross-sectional imaging and bronchoscopic evaluation showed moderate to severe distal tracheomalacia with anterior and posterior tracheal compression resulting from severe mediastinal rotation secondary to right-sided CSL. It was determined that her tracheal compression was mainly caused by her aortic arch wrapping around the trachea, with possible additional posterior compression of the esophagus by the ARSA. She first underwent intrathoracic tissue expander placement, which resulted in immediate improvement of tracheal compression. Two days later, she developed symptoms of dysphagia lusoria due to increased posterior compression of her esophagus by the ARSA. She underwent transposition of ARSA to the right common carotid with immediate resolution of dysphagia lusoria. As the patient grew, additional saline was added to the tissue expander due to recurrence in compressive symptoms., Conclusions: Concurrent presentation of CSL and ARSA is extremely rare. Asymptomatic CSL and ARSA do not require surgical interventions. However, if symptomatic, it is crucial to involve a multidisciplinary team for surgical planning and to take a step-wise approach as we were able to recognize and address both tracheomalacia and dysphagia lusoria in our patient promptly.

Background: An aberrant right subclavian artery which arises from the proximal descending aorta may result in aortic dissection. The dissection may occur at either the site of the primary intimal tear or from an aortic branch. These conditions may lead to blood flow limitation and possible aneurysmal degeneration in the future., Case Presentation: We described the clinical presentation and management of a 54-year old patient diagnosed with a rare case of an aberrant right subclavian artery with Stanford Type B aortic dissection. A hybrid surgical approach was successfully performed and the patient had an uneventful recovery., Conclusion: Even though aortic dissection is often an incidental finding, this case highlighted that in rare situations, it can be associated with an aberrant right subclavian artery. It is important to disseminate this association as it has profound diagnostic and therapeutic implications in safeguarding the clinical outcomes of patients with such condition.

Objective: This study sought to summarize the clinical experience of surgical treatment of anomalous origin of pulmonary arteries from the ascending aorta (AOPA) in Fuwai hospital., Methods: Fifty-two patients (28 males, 17.2 ± 27.2 months old and 8.7 ± 10.2 Kg weight) who have AOPA undertook surgical treatment between 1998 and 2017 were reviewed in this study, 47 out of 52 are anomalous origin of the right pulmonary artery (AORPA), among the rest of the patients are anomalous origin of left pulmonary artery (AOLPA). 27 out of 52 associate with simple cardiac abnormalities, 20 out of 52 associate with complex cardiac malformations, the remaining 5 patients without cardiac abnormalities. Among all patients who underwent surgical treatment, the direct end-to-side anastomosis strategy was applied in 26 patients, autologous pericardial-homograft patch and aortic flap were employed in 20 patients, and synthetic graft was used in 6 patients., Results: No patient died during the perioperative period. 50 out of 52 patients were followed-up for 100.1 ± 70.9 months. The rate of pulmonary arterial free restenosis for 2 years, 5 years, and 10 years is 98.0, 96.0 and 92.0%, respectively., Conclusions: The correct diagnosis and appropriate surgical treatment for AOPA could obtain excellent early and medium-term result.

Backround: The right aortic arch and aortic coarctation are rare congenital anomalies with the incidence of 0.1% and 0.03-0.04%. We present a case report of a 51-year-old woman with the right aortic arch with aberrant left subclavian artery and coarctation of the aorta with post-stenotic aneurysm., Case Presentation: Resection of the coarctation and aneurysm with replacement by tubular prosthesis was performed on partial cardiopulmonary bypass via femoral vessels., Conclusion: Partial cardiopulmonary bypass is an applicable method for ensuring the perfusion of the distal part of the body and an aberrant left subclavian artery is not a contraindication of this technique.

Background: An aberrant right subclavian artery (ARSA) is a relatively prevalent vascular anomaly. What is the most appropriate treatment for thoracic aortic aneurysm combined a non-aneurysmal change ARSA?, Case Presentation: A 52-year-old man was admitted to our institute due to a history of chronic cough, dysphagia and an abnormal chest radiographic finding. Because of his progressive symptoms and large fusiform thoracic aneurysm, we performed the hybrid repair for simultaneous relief of an ARSA causing dysphagia and thoracic aneurysm., Conclusion: In case without aneurysm of ARSA, especially in conjunction with approximate thoracic aneurysm, our approach is suitable because the revascularization using the right carotid to subclavian artery re-routing prior to endograft deployment is justified in order to preserve circulation of posterior brain, spinal cord, internal mammary artery and upper limb and to prevent large retrograde type II endoleaks, as well as simplicity and durability.

Background: A 59-year old man being investigated for back pain was found to have aneurysmal dilatation of a right-sided aortic arch and descending thoracic aorta together with an aberrant left subclavian artery., Case Presentation: He underwent repair of this utilising the frozen elephant trunk technique, which dealt with all three pathologies in one-stage. He made an unremarkable recovery and was discharged home on the 8th post-operative day., Conclusions: This case report further demonstrates the flexibility and safety of the frozen elephant trunk in dealing with complex aortic pathology as a single-stage procedure.

Aberrant right subclavian artery is the most common anomaly of the aortic arch. Patients are often asymptomatic and discovered accidentally. Occasionally, they present with symptoms related to oesophageal or tracheal compression.A 13-year-old girl presented with dysphagia and stridor was found to have an aberrant right subclavian artery. Surgical division and reconstruction of the artery was performed initially through right supraclavicular approach. An additional left thoracotomy was performed to overcome the challenges encountered at initial operation.

Aberrant right subclavian artery with coexisting common carotid trunk is an extremely rare congenital anomaly affecting <0.1% of the population. We report the case of a 77-year-old Caucasian man presenting with dysphagia and dyspnea secondary to an aberrant right subclavian artery aneurysm and describe our technique for open surgical repair.

A 57-year-old Chinese male patient presented with Standford type A aortic dissection with an aberrant right subclavian artery (ARSA). At operation, the ascending aorta was replaced by a mono-branch vascular prosthesis with the branch bypassing to the ARSA; the triple-branched stent graft was inserted into the true lumen of the arch and proximal descending aorta (covering the origin of the ARSA) with each sidearm graft being positioned into the aortic branches; and then its proximal end was sutured to mono-branched vascular prosthesis. Follow-up computed tomography angiography showed false lumen of the dissection disappeared with satisfactory position of the triple-branched stent graft.
