A 43-year-old asymptomatic patient was diagnosed with an azygos vein aneurysm on contrast-enhanced computed tomography; at the 5-year follow-up, contrast-enhanced computed tomography revealed development of an azygos vein aneurysm. However, preoperative contrast-enhanced computed tomography at our hospital showed thrombus development along with shrinkage of the azygos vein aneurysm. To prevent thrombus dissemination, we decided to perform surgery. The aneurysm was excised via video-assisted thoracoscopic surgery, and the patient recovered uneventfully. Thoracoscopic surgery is effective in managing azygos vein aneurysms and preventing embolisms in thrombotic aneurysms. This procedure was chosen to avoid excessive compression of aneurysms and to prevent pulmonary embolism. This report presents a case of surgical management of an idiopathic azygos vein aneurysm with thrombosis.Clinical registration number 2020-S-20.
Abstract Objective Azygos vein aneurysms (AVAs) are uncommon and infrequently diagnosed. When confronted with a patient presenting with an AVA, physicians can rely on only a few case reports after an extensive literature search. To date, no guideline, no rule, and no review on the optimal treatment strategy for these patients exist. Methods A PubMed and MEDLINE database search for papers and case reports describing AVA was performed. Cases from our own institutions were also reviewed. Results Th...

Background Idiopathic azygos vein aneurysm (AVA) is rare. This retrospective study evaluated the imaging features and outcomes in 10 cases of idiopathic AVA. Methods We retrospectively evaluated 10 patients with surgically proven or typical imaging features of idiopathic AVA encountered in our institution between 1990 and 2012. Chest roentgenography and computed tomography (CT) were performed in all 10 patients, and magnetic resonance imaging (MRI) was performed in 4 of these patients. The clini...

We report a resection of an azygos vein aneurysm that formed a thrombus during a 6-year follow-up period. An azygos vein aneurysm is commonly detected as an asymptomatic mediastinal mass. A thrombus could suddenly form without enlarging the aneurysm. Therefore we suggest that even asymptomatic azygos vein aneurysms causing blood stagnation should be resected before they can form a thrombus and cause a pulmonary embolism.
Aneurysm of the azygos vein is rare. We describe the case of a 51-year-old nonsmoking woman with a posterior mediastinal mass caused by a giant azygos vein aneurysm with subtotal thrombosis. Surgical resection of the azygos vein was offered to our patient as a treatment option owing to theoretical risks of rupture and pulmonary embolism. After taping the azygos vein proximally and distally, the aneurysm was resected with video-assisted thoracoscopy. Approximately 30 cases have been reported in t...

A giant venous varix of the azygos arch is a very rare cause of a mediastinal mass. The usual diagnosis of a mediastinal mass by mediastinoscopy or percutaneous fine-needle aspiration or biopsy is very hazardous if there is a venous varix. Noninvasive thoracic CT scanning is a safe and better choice for diagnosis. We describe the case of a woman with a posterior mediastinal mass caused by a giant azygos vein varix. Thoracic CT documented the diagnosis. The etiology of the azygos varix was portal...
