Interruption of the inferior vena cava IVC) with azygos continuation is an uncommon vascular anomaly that results from aberrant development during embryogenesis. We report a rare case of this anomaly, presenting with massive pulmonary embolism. Subsequent evaluation with abdominal CT scan revealed the congenital absence of retrohepatic IVC. The patient was successfully treated with anticoagulation. When deep venous thrombosis (DVT) develops in patients with no apparent risk factors, the presence of congenital IVC anomalies should be considered.

2.Ultrasound diagnosis of left inferior vena cava and double inferior vena cava in fetus.
Journal of Zhejiang University. Medical sciences 2019;48(4):446-452
OBJECTIVE:
To evaluate the application of ultrasonography in prenatal diagnosis of left inferior vena cava and double inferior vena cava in fetus.
METHODS:
The clinical data and ultrasonographic findings of the fetuses with left inferior vena cava (18 cases) or double inferior vena cava (16 cases) were retrospectively analyzed.
RESULTS:
The ultrasonographic images of left inferior vena cava showed that in the transverse view of the fetal upper abdomen the inferior vena cava and abdominal aorta were in the normal position; below the level of the hilum, the inferior vena cava was located behind the left side of the abdominal aorta; at the level of the hilum, it crossed the front of the abdominal aorta and run diagonally to the upper right, forming the right inferior vena cava and finally entered into the right atrium. The ultrasonographic images of double inferior vena cava showed that in the transverse view of the fetal lower abdomen, in front of spine there were three transections of blood vessels; in coronal plane of abdomen, the veins run on both sides of the abdominal aorta and entered to the iliac vein of the same side. In 34 cases of abnormal inferior vena cava, there were 17 cases complicated with other system abnormalities, including 13 cases of cardiac anomalies.
CONCLUSIONS
The left inferior vena cava and double inferior vena cava have characteristic imaging findings, and prenatal diagnosis can be made with ultrasonography. This type of congenital deformity is frequently complicated with other system abnormalities, which should be excluded in fetus, especially for heart system.

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cyst. Recently, we observed a Eustachian valve cyst diagnosed on MDCT showing a hypodense cyst at the characteristic location of the Eustachian valve (the junction of the right atrium and inferior vena cava). MDCT also demonstrated additional cardiovascular anomalies including atresia of the coronary sinus ostium and a persistent LSVC and bicuspid aortic valve.

Various anatomic anomalies have been considered the causes of nutcracker syndrome (NCS). Posterior NCS refers to the condition, in which vascular narrowing was secondary to the compression of the retroaortic left renal vein while it is crossing between the aorta and the vertebral column. Here, we report an unusual case of posterior NCS associated with a complicated malformation of the interrupted left inferior vena cava with azygos continuation and retroaortic right renal vein, diagnosed by both color Doppler ultrasonography and CT angiography.

Anomalies of renal vasculature combined with ectopic kidneys were found on a multi-detector CT scan. Knowledge of renal vascular variation is very important for surgical exploration, radiologic intervention and staging for urologic cancer. We present an extremely rare case of a right circumaortic renal vein combined with a right ectopic kidney. The right kidney was located at the level between the third and fifth lumbar vertebra. The right circumaortic renal vein crossed the aorta and returned to the inferior vena cava behind the aorta.

The absence of the inferior vena cava is an uncommon congenital anomaly that has recently been identified as an important risk factor contributing to the development of deep venous thrombosis. Congenital agenesis of the right hepatic lobe is a rare anomaly which is found incidentally in radiologic examinations. We present a case of a congenital absence of the infrarenal inferior vena cava, combined with agenesis of the right hepatic lobe in a 62-year-old man presented with symptoms of deep venous thrombosis.

Situs inversus of the abdominal organs in the presence of normally placed heart on the left side of the thorax is known as situs inversus with isolated levocardia. This rare condition is commonly associated with severe congenital defects of the heart. We report a case of situs inversus with levocardia in a 19-year-old asymptomatic male patient with completely normal heart on the left chest. Spiral computed tomography of the thorax and abdomen and echocardiographic studies revealed situs inversus of abdominal organs, normal heart (levocardia), mirrored left lungs, a midline liver, a left-sided inferior vena cava connecting to the right atrium, multiple splenic masses in the abdominal right upper quadrant, and aneurysmal dilatation of a splenic artery.

Inferior sinus venosus ASD (atrial septal defect) is a rare congenital cardiac deformity, that occurs on between the inferior vena cava and right atrium. Diagnosis of inferior sinus venosus ASD is difficult because of its infero-posterior location of the fossa ovalis. Therefor, exact anatomical diagnosis by preoperative and intraoperative transesophageal echocardiography is necessary at preoperation and during the operation. We present a case of residual ASD, which was diagnosed secundum ASD and repaired when the patient was 10 years old. Residual ASD was diagnosed by cardiac echocardiography in preparation of otorhinolaryngology operation. Therefore, reoperation of residual ASD was done when the patient was 24 years old. The patient had secundum ASD and inferior sinus venosus ASD, but in the prior operation, inferior sinus venosus ASD wasn't found and only secundum ASD was repaired. In reoperation, inferior sinus venosus ASD was reveled and patch closure was done.
