Inferior vena cava agenesis (IVCA) is an uncommon congenital anomaly which was first described in the seventeenth century. The detection of such an anomaly is often incidental and patients are asymptomatic until the third to fourth decade of life. Due to the scarcity of these cases, there is no consensus on the subsequent treatment and surveillance of incidental asymptomatic IVC anomalies. Herein, we report on a young male with incidental findings of suprarenal IVC agenesis identified on contrast enhanced computed tomography (CT) scan of the abdomen in the course of treatment for acute appendicitis.

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.

Right double inferior vena cava with obstructed retrocaval ureter is an extremely rare anomaly with only a few reported cases in the literature. To the best of our knowledge, this is the first case report describing ureteric repair by use of a single-incision laparoscopic technique. In addition, this report addresses the underlying surgical challenges of this repair and provides a brief review of the embryology of this anomaly. The "Santosh Postgraduate Institute ureteric tacking fixation technique" provides ease of end-to-end uretero-ureteric anastomosis in a single-incision laparoscopic surgery.

Congenital extrahepatic portocaval shunt (CEPS) is a rare anomaly of the mesenteric vasculature in which the intestinal and splenic venous drainage bypasses the liver and drains directly into the inferior vena cava, the left hepatic vein or the left renal vein. This uncommon disease is frequently associated with other malformations and mainly affects females. Here we report a case of pulmonary arterial hypertension associated with CEPS (Abernethy type 1b shunt) in a 20-yr-old man who was incidentally diagnosed during evaluation of multiple nodules of the liver. The patient was treated by inhalation of iloprost (40 microg/day) with improved condition and walking test. Physicians should note that congenital portocaval shunt may cause pulmonary hypertension.

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.

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.

Congenital anomalies of the inferior vena cava are rare. Such anomalies pose great challenges to the surgeon in neuroblastoma surgery, especially when unrecognised preoperatively. We report the first case of an abdominal neuroblastoma detected in a child with a developmental anomaly of the left-sided inferior vena cava. The patient underwent surgical resection after good response to preoperative chemotherapy.

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.

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.

Inferior sinus venosus type atrial septal defect (ASD) is a rare congenital cardiac deformity that occurs between the inferior vena cava and right atrium. Inferior sinus venosus defect is difficult to diagnose through transthoracic echocardiography because of its location which is infero-posterior to the fossa ovalis. Increasing pulmonary arterial pressure and pulmonary vascular resistance in patients with sinus venosus defect usually occur earlier than other types of ASD. We report a case of 19-year-old man who presented exertional dyspnea due to inferior sinus venous type ASD with mild pulmonary hypertension. In this case, we found clues from slight diastolic flattening of interventricular septum and shortened acceleration time of right ventricular outflow tract on initial transthoracic echocardiography, leading right heart catheterization and transesophageal echocardiography to reveal this rare type of ASD.
