Unreliable Indicator of Azygos Continuation of the Inferior Vena Cava
نویسنده
چکیده
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, however, indicate that AC-IVC is frequently associated with

Heterotaxy syndrome and interrupted inferior vena cava (IVC) with azygos continuation
Heterotaxy syndrome or situs ambiguous is a rare congenital disease in which the pattern of anatomical organization of the thoraco-abdominal visceral and vascular structures is not arranged in normal position. Patients with heterotaxy syndrome represent a wide range of anatomical variations including thoraco-abdominal structures. Here we report a rare case of asymptomatic heterotaxy syndrome in...

متن کاملSuccessful radiofrequency ablation of a right posteroseptal accessory pathway through an anomalous inferior vena cava and azygos continuation in a patient with incomplete situs inversus.
We present a 43-year-old patient with paroxysmal supraventricular tachycardia. In the process of catheter ablation, we found interruption of the inferior vena cava with azygos continuation with incomplete situs inversus. In this patient, we adopted the lower approach via the anomalous inferior vena cava and azygos continuation to achieve stability of radiofrequency catheter for right posterosep...
متن کاملSuccessful ablation of atrioventricular nodal re-entrant tachycardia in a patient with interruption of inferior vena cava and azygos continuation.
Congenital anomalies of the venous system are a challenge for cardiac catheterization and radiofrequency ablation. This article describes ablation of atrioventricular nodal re-entrant tachycardia performed solely through the azygos continuation in a patient with inferior vena cava interruption.
متن کاملDuplication of the inferior vena cava with azygos continuation, retroaortic left renal vein and iliac vein variations.
UNLABELLED We present a rare complex variation of the inferior vena cava and internal iliac veins demonstrated by a multidetector computed tomography. It was shown that patient had double inferior vena cava with azygos continuation of the right inferior vena cava, retroaortic left renal vein and the left and right internal iliac veins converged and drained to the right external iliac vein throu...
