Migrating azygos vein and vanishing azygos lobe: MDCT findings.
OBJECTIVE The purpose of this study was to describe six cases of migrating azygos vein and to explain the etiologic factors that contribute to the migration. Six patients with migrating azygos vein were studied by MDCT before and after migration. Five patients had right pneumothorax. All patients had repeated episodes of cough, vomiting, and a short mesoazygos. CONCLUSION Pneumothorax, increa...
متن کاملLeft superior vena cava with left azygos vein.
An incidence of a left superior vena cava with a left azygos vein was found in a cadaver during an Osaka Dental University student's dissection practice session in 2002. The left superior vena cava began from the confluence between the right and left brachiocephalic veins, and extended directly into the left superior edge of the coronary sinus. No right superior vena cava was observed. The left...
متن کاملImpressive dilatation of azygos vein due to congenital anomaly of inferior vena cava.
A right-sided thoracotomy was performed for pulmonary metastases in an asymptomatic patient. Preoperative computed tomography (CT) scan showed partial thrombosis or agenesis of the inferior vena cava (Fig. 1). Intra-operatively, an impressive dilation of the azygos vein was noted (Fig. 2). The azygos vein or superior vena cava was not invaded by tumour. Fig. 1. Preoperative thoracic CT scan sho...
متن کاملThe Abnormally Situated Azygos Vein
The azygos vein may be abnormally situated due to anomalous embryologic development. Its abnormal location is infrequent, but radiologic recognition is much easier than that of the normal vein. This vein, normal or abnormal, becomes distended in conditions with an elevated venous pressure, systemic or portal. Changes in the size of the azygos vein on x-ray are noted to parallel fluctuations of ...
متن کاملUnreliable Indicator of Azygos Continuation of the Inferior Vena Cava
Recognition of azygos continuation of the inferior vena cava (AC-IVC) is necessary to prevent unnecessary surgery, to modify the approach to right heart catheterization and to avoid potentially fatal azygos ligation at the time of thoracic surgery. Absence of the inferior vena cava (IVC) shadow on the lateral chest film has been claimed to be an important feature of AC-IVC. Our findings, howeve...
