ABSTRACT
Azygos vein aneurysm is a rare thoracic disease that often mimics posterior mediastinum tumors. Pathogenesis of azygos vein aneurysm is unclear. Discussions about possible causes are still ongoing. Most aneurysms are asymptomatic and diagnosed incidentally during standard examinations. Severe complications of azygos vein aneurysm include rupture with massive bleeding and pulmonary embolism. Contrast-enhanced chest CT and MRI are essential. Differential diagnosis includes tumors, cysts and rare neoplasms of the mediastinum. Treatment algorithm is not established. There are traditional surgical and endovascular methods. We present minimally invasive surgical treatment of azygos vein aneurysm in a 53-year-old woman. The patient underwent thoracoscopic resection of aneurysm. Histological examination revealed a partially thrombosed azygos vein aneurysm.

Intrahepatic interruption of the inferior vena cava (IVC) with continued hemizygous is a very rare abnormality and sometimes it may be accompanied by other cardiovascular abnormalities. Continuation of the hemizygous vein draining into the right atrium through the left superior vena cava (LSVC) is much rarer. In this paper, we have presented a patient who had simultaneous IVC interrupted with persistent LSVC and suffered from Atrioventricular nodal reentrant tachycardia (AVNRT). Finally, radiofrequencies (RF) catheter ablation for AVNRT was successfully performed through a left subclavian vein access.

Congenital anomalies of respiratory system are quite diverse and not all of them are subject to surgical treatment. One example is accessory lobe of the azygos vein. This anomaly usually has no clinical manifestations and requires only follow-up, as well as attention in surgery on the right half of the chest for some other disease. This situation changes when complications occur, for example, purulent-inflammatory process. Therapy is not always effective, and lung tissue destruction requires surgical treatment. Progressive destruction complicates diagnosis and choosing surgical tactics. We present a rare case of severe purulent-inflammatory complication with abscess in accessory lobe of v. azygos. Anatomical abnormalities following this congenital pulmonary anomaly can cause difficulties in surgeries for other intra-thoracic diseases. The situation is especially relevant for thoracoscopic access. This report will be useful for radiologists, pulmonologists and thoracic surgeons.

BACKGROUND: The malposition of central venous catheters (CVCs) may lead to vascular damage, perforation, and even mediastinal injury. The malposition of CVC from the right subclavian vein into the azygos vein is extremely rare. Here, we report a patient with CVC malposition into the azygos vein via the right subclavian vein. We conduct a comprehensive review of the anatomical structure of the azygos vein and the manifestations associated with azygos vein malposition. Additionally, we explore the resolution of repositioning the catheter into the superior vena cava by carefully withdrawing a specific length of the catheter. CASE PRESENTATION: A 79-year-old female presented to our department with symptoms of complete intestinal obstruction. A double-lumen CVC was inserted via the right subclavian vein to facilitate total parenteral nutrition. Due to the slow onset of sedative medications during surgery, the anesthetist erroneously believed that the CVC had penetrated the superior vena cava, leading to the premature removal of the CVC. Postoperative contrast-enhanced computed tomography of the chest confirmed that the central venous catheter had not penetrated the superior vena cava but malpositioned into the azygos vein. The patient was discharged 15 days after surgery without any complications. CONCLUSIONS: CVC malposition into the azygos vein is extremely rare. Clinical practitioners should be vigilant regarding this form of catheter misplacement. Ensuring the accurate positioning of the CVC before each infusion is crucial. Utilizing chest X-rays in both frontal and lateral views, as well as chest computed tomography, can aid in confirming the presence of catheter misplacement.

Intraluminal tumor in the azygos vein is a rare disease that can cause superior vena cava (SVC) syndrome. Radiotherapy and endovascular stenting with or without chemotherapy are reported to have a high clinical success rate for the management of SVC syndrome with malignancy, but a poor survival rate. Here, we report a 69-year-old man who presented with swelling of the face and upper extremities, who was diagnosed with SVC syndrome caused by an intraluminal tumor in the azygos vein. Enhanced chest computed tomography revealed an intraluminal mass with a filling defect from the azygos vein to the SVC, with no extravascular extension or dissemination of the primary tumor. Surgical resection of the mass en bloc with the azygos vein and SVC reconstruction was performed. A poorly differentiated carcinoma was diagnosed on postoperative pathological evaluation. Twelve months after resection, the patient was well with no signs of recurrent disease. This case highlights that surgical resection should be considered as a treatment of choice for the management of SVC syndrome caused by an intraluminal malignancy in the azygos vein.

A 63-year-old woman was admitted to our department for the investigation of superior vena cava (SVC) syndrome. Computed tomography revealed an azygos tumor extending into the SVC. Video-assisted thoracic surgery (VATS) was performed to remove the distal end of the azygos vein in the left lateral position, followed by complete resection of the entire tumor under median sternotomy in the supine position. The histological diagnosis was a primary angiosarcoma of the azygos vein. The patient was discharged without any complications and is now alive and tumor-free 24 months after surgery. In addition, contrast-enhanced computed tomography revealed no graft occlusion in the two reconstructed brachiocephalic veins. Thoracoscopic surgery in the lateral position is useful for safe and reliable complete resection of a tumor arising from the azygos vein.

Since the first successful repair of esophageal atresia/tracheoesophageal fistula (EA-TEF) was performed approximately 8 decades ago, surgeons have made considerable technical advances in solving intraoperative surgical challenges and reducing postoperative complications. According to some surgeons, preserving the Azygos vein makes this modification attractive. This study aimed to evaluate the benefits of preserving the Azygos vein during surgery for esophageal atresia with tracheoesophageal fistula and to highlight its advantages in reducing anastomotic leak, stricture, and other postoperative outcomes. This prospective comparative series was conducted between April 2020 and April 2023. The study included all newborns with EA-TEF eligible for primary repair. Patients were randomized to either Group A or B. Group A underwent Azygos vein preservation, whereas the remaining patients (Group B) underwent Azygos vein disconnection. Sixty-four patients were included in this study. Thirty-two patients (Group A) underwent Azygos vein preservation during EA-TEF repair, and the remaining thirty-two patients (Group B) underwent Azygos vein ligation and disconnection. Both groups were comparable in terms of demographics, clinical data, and operative findings (P > 0.05). Pneumonitis occurred in 4 patients in Group A and 16 patients in Group B. Anastomotic leaks occurred in two (6.2%) patients in Group A and six (18.7%) patients in Group B. There were two deaths in Group A and six deaths in Group B, with a significant difference between the two groups (P = 0.0485). Preserving the Azygos vein during esophageal atresia repair reduces the occurrence of postoperative pneumonia, leakage, and stenosis, and decreases postoperative mortality. Therefore, we declare that this modification is a significant and valuable addition to the current surgical procedures.

BACKGROUND: The purpose of this study was to investigate the effect of our revamped MIE-McKeown operation on postoperative gastrointestinal function recovery. METHODS: This revamped MIE-McKeown operation without removing azygos vein arch, bronchial artery and vagus nerve trunk and with the tubular stomach buried throughout esophageal bed and azygos arch, has been implemented from July 2020 to July 2021 by the same medical team of Gaozhou People's Hospital thoracic surgery for 13 times. Preoperative clinical data, main intraoperative indicators and postoperative complications were observed. RESULTS: All patients had esophageal malignant tumors at the level of middle and lower thoracic non-azygous venous arch, with preoperative clinical stage CT1-2N0M0 stage i-ii. V-vst test was performed on the 7th postoperative day, and 10 patients were found to have no loss of safety/efficacy. There were 2 cases with impaired efficacy and no impaired safety, 1 case with impaired safety. There were 1 cases of pulmonary infection, 1 cases of anastomotic fistula combined with pleural and gastric fistula, 2 cases of hoarseness, 2 cases of arrhythmia, 10 cases of swallowing function were grade i, 2 cases of swallowing function were grade iii, 1 case of swallowing function was grade iv in watian drinking water test one month after operation. CONCLUSIONS: Merit of this revamped MIE-McKeown operation is well preserving the integrity of azygos arch of vagus nerve and bronchial artery, and it is technically safe and feasible. No postoperative mechanical obstruction of thoracostomach, huge thoracostomach and gastrointestinal dysfunction occurs.

BACKGROUND: The one-and-a-half ventricle repair (1.5VR) is an option for definitive surgery of cardiac defects with hypoplastic right ventricle (RV). The 1.5VR with open azygos vein was reported to provide a theoretical advantage of decompressing the supra vena cava (SVC) or the right atrium in patients with SVC hypertension or severe RV dysfunction. The aim of this study is to review and evaluate our experience with this procedure in the long-term period. METHODS: Medical records of the patient undergoing 1.5VR with open azygos vein between January 2000 and December 2019 were reviewed retrospective. Pre- and postoperative echocardiography and cardiac catheterization data were also analyzed. RESULTS: 4 patients underwent the 1.5VR with open azygos vein. The median age at time of surgery was 2.2 years, and the median weight was 9.8 kg. The median tricuspid valve (TV) Z-score was - 3.5, the median right ventricular end-diastolic volume (RVEDV) was 54.0% of normal. There were no operative death and early adverse events. Median follow-up time was 17.1 years. There were no late death and re-operation during the follow-up. The postoperative TV diameter and RVEDV were larger than preoperative data in 3 of 4 patients. CONCLUSIONS: The 1.5VR with open azygos vein is a good surgical option for congenital heart disease with hypoplastic RV. The TV and RVEDV may grow and biventricular conversion may be possible.

BACKGROUND: Azygos vein aneurysms (AVAs) are extremely rare. The majority of patients have no obvious clinical symptoms, so they are found by physical examination or by chance. There is limited clinical treatment experience that can be referred to, and there are no clear guidelines or research evidence standardizing the surgical and interventional therapy. Here, we report a patient with idiopathic AVA whose three-dimensional reconstruction of the tumor was completed before surgery. On the basis of three-dimensional reconstruction, single-port thoracoscopic resection of the AVA was successfully completed and reported for the first time. The previously reported cases are summarized to provide guidance for the diagnosis and treatment of patients with AVAs. CASE PRESENTATION: A 56-year-old man was transferred to our hospital due to "dysphagia". The diagnosis of AVA was made after enhanced computed tomography, gastroscopy, fiberoptic bronchoscopy, and three-dimensional reconstruction. Congenital weakness or degenerative changes causes the vein walls to be extremely thin that the AVA had the risk of ruptur. Furthermore, the patient had symptoms of dysphagia, he received single-port thoracoscopic surgery. After the operation, his dysphagia disappeared. The postoperative pathology confirmed hemangioma. The patient was discharged 3 days after surgery without any complications. CONCLUSIONS: AVAs are rare. Preoperative three-dimensional reconstruction can greatly help surgeons clarify the disease diagnosis, formulate the surgical plan, avoid damage to the surrounding vital organs, and reduce intraoperative bleeding. Thoracoscopic surgery to remove AVAs is difficult and has a high risk of bleeding, while more minimally invasive single-port thoracoscopic surgery is also safe and effective for the treatment of AVAs.

BACKGROUND: Azygos vein aneurysm (AVA) is a rare thoracic pathological entity that mimics a posterior mediastinal mass. However, the pathogenesis of primary azygos vein aneurysms is not clear and its pathology is still being discussed. Some of the AVA are asymptomatic and usually discovered accidentally by routine physical examination. CASE PRESENTATION: We report the case of a 37-year-old woman who had an azygos vein arch aneurysm with no obvious clinical symptoms. With the analysis of clinical features of the case and AVA morphological characteristics, the AVA was found by a chest computed tomography. Then, enhanced chest computed tomography showed a soft-tissue mass (4.9 × 3.7 × 3.2 cm) in the right posterior mediastinum, which was connected to the superior vena cava and significantly enhanced with contrast agent stratification. The density of the tumor in the delayed stage was the same as that in the azygos vein. The patient underwent video-assisted thoracoscopic surgery. Histopathological evaluation of the surgical biopsy specimen proved to be a completely thrombosed aneurism of the azygos vein arch. CONCLUSIONS: AVA is a rare pathology that must be taken into consideration during the differential diagnosis of right posterior mediastinal masses. Thoracoscopic surgery is one of the most preferred treatment options for azygos vein aneurysm.

BACKGROUND: Esophagogastric variceal bleeding is the most common lethal factor for patients with cirrhotic portal hypertension. We firstly developed a laparoscopic splenectomy and azygoportal disconnection (LSD) with intraoperative endoscopic variceal ligation (LSDL) technique. In this study, we aimed to evaluate whether LSDL is feasible and safe and whether LSDL can effectively prevent esophagogastric variceal re-bleeding (EVR), as compared with single LSD. METHODS: In this randomized controlled single-center study, 88 patients with cirrhosis who had esophagogastric variceal bleeding and hypersplenism were randomly assigned to receive either LSD (n = 44) or LSDL (n = 44) between January 2020 and December 2021. The primary outcome was EVR. RESULTS: No patients withdrew from the study. There were no significant differences in estimated blood loss, incidence of blood transfusion, time to first flatus and off-bed activity, or postoperative hospital stay between the two groups. Compared with that in the LSD group, operation time was significantly longer in the LSDL group (138.5 ± 19.4 min vs. 150.3 ± 19.0 min, P < 0.05); however, LSDL was associated with a significantly decreased EVR rate at 1-year follow-up (8/44 vs. 1/44, P < 0.05). Univariate analysis and multivariate logistic regression revealed that LSDL was a significant independent protective factor against EVR in comparison with LSD (relative risk: 0.105, 95% confidence interval 0.012-0.877; P = 0.037). CONCLUSIONS: Our newly developed LSDL procedure is not only technically feasible and safe; it also contributed to lowering the EVR risk more so than single LSD.

INTRODUCTION: Situs inversus totalis, dextrocardia with interrupted inferior vena cava, and azygos vein continuation concomitant with symptomatic atrial fibrillation requiring ablation. This case was deemed not suitable for percutaneous ablation due to anatomic variations and the lack of case reports in the literature. METHODS AND RESULTS: We performed bilateral thoracoscopic epicardial ablation and epicardial left atrial appendage exclusion. The direct vision allowed for a complete box lesion set with bipolar radiofrequency device. Patient remained in sinus rhythm at the 12-months follow-up. CONCLUSION: Surgical thoracoscopic epicardial ablation is safe and effective also in congenital defects. Multidisciplinary expertise can offer minimally invasive ablation treatments.

Azygos vein aneurysm (AVA) is necessary to prevent pulmonary embolism due to the outflow of a thrombus or rupture of the aneurysm. However, there is no established modality to assess the properties of AVA. Time-resolved three-dimensional phase-contrast magnetic resonance imaging (4D-flow MRI) has been used to examine the hemodynamics in various fields. We report a case of AVA to evaluate the flow variability and adhesions of surrounding tissues using 4D-flow MRI. The findings of the study suggested aneurysm turbulence and the absence of thrombi. The cine image, which showed a sliding wall synchronized to the heartbeat, indicated no adhesion to the superior vena cava. Based on these results, the thoracoscopic approach was deemed possible preoperatively. Thoracoscopic AVA resection was performed, and the postoperative course was uneventful. This study documented the utility of 4D-flow MRI for a detailed evaluation of AVA.

Partial anomalous pulmonary venous return into the azygous vein is a rare pathological finding. We describe the case of a 28-year-old girl who had a successful staged approach to treat this rare congenital heart disease. To avoid potential connection of a systemic venous return to the left atrium, the proximal part of the azygous vein was occluded with a percutaneous approach, then the azygous vein flow was redirected into the left atrium with a surgical procedure.

BACKGROUND: Mediastinal hemangiomas are rare, and their etiology remains unclear. Most patients affected have no pathognomonic clinical symptoms, and the diagnosis is often incidental. Due to the paucity of the available literature regarding the management of this disease, the choice and timing of treatment remains controversial. CASE PRESENTATION: Herein, we report the case of a hemangioma of the azygos vein arch in a 66-year-old woman who presented with dyspnea, chest discomfort, dysphagia, and weight loss. A simultaneous right chylothorax refractory to conservative management was found. A CT-guided biopsy of the mass was performed, and it confirmed the vascular nature of the lesion. Therefore, the patient underwent an angiography followed by endo-vascular embolization. Three days later, thoracoscopic surgical resection of the mass and the repair of the chyle leakage were performed safely. The patient was discharged uneventfully on postoperative day seven, with complete resolution of all the presenting symptoms. CONCLUSIONS: Treatment of symptomatic mediastinal hemangiomas could be mandatory, but a thorough multidisciplinary approach to these rare malformations is essential. Despite the risk of intraoperative bleeding, selective endovascular embolization followed by thoracoscopic surgery allowed for a complete and safe resection with a good outcome.

Balloon atrial septostomy is a palliative procedure that is performed in D-transposition of great arteries when surgery is not immediately available. Although D-TGA and left isomerism association are rare, it is an important condition as the BAS procedure approach is unique. In this case report, we present two cases of D-TGA with left isomerism where BAS was performed due to restrictive atrial septal defect and lack of immediate availability of the paediatric cardiac surgeon.
