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.

A complete surgical resection is the only proven therapeutic modality that prolongs the survival in patients with leiomyosarcoma of the inferior vena cava (IVC). Reconstruction of the IVC is not always necessary but is often required to facilitate venous drainage of the kidney for the tumors at the pararenal area of the IVC. Controversy exists in postoperative adjuvant therapy. Recently, we experienced four cases of pararenal leiomyosarcoma of the IVC, of which treatment consisted of a complete resection of the tumor, ringed polytetrafluoroethylene (PTFE) graft interposition, and bilateral renal vein reconstructions in all patients. Postoperative radiation therapy was instituted in 3 of 4 patients. One patient who did not receive the postoperative radiation therapy was treated with adjuvant chemotherapy. The kidneys were preserved in all patients and no deep vein thrombosis (DVT) or venous insufficiency of the lower extremity veins developed. Distant metastasis to the lung was noted in one patient at 18 months after surgery, who was not received the postoperative radiation therapy but chemotherapy. In conclusion, a complete resection of the tumor, IVC reconstruction, and bilateral renal vein reconstruction followed by adjuvant radiation therapy is recommended for the treatment of pararenal leiomyosarcoma of the IVC.

A 58-year-old female patient, diagnosed with adenocarcinoma of the lung, underwent percutaneous vertebroplasty at the L4 vertebral body due to painful spinal metastases. Because of deep venous thrombosis of the left femoral and iliac veins, an inferior vena cava filter had been placed before vertebroplasty. Bone cement migrated into the venous bloodstream and then was being trapped within the previously placed filter. This case illustrates that caval filter could capture the bone cement and prevent it from migrating to the pulmonary circulation.

OBJECTIVE: To determine the feasibility of transcaval transjugular intrahepatic portosystemic shunt (TIPS) in patients with occluded previous TIPS. MATERIALS AND METHODS: Between February 1996 and December 2000 we performed five transcaval TIPS procedures in four patients with recurrent gastric cardiac variceal bleeding. All four had occluded TIPS, which was between the hepatic and portal vein. The interval between initial TIPS placement and revisional procedures with transcaval TIPS varied between three and 31 months; one patient underwent transcaval TIPS twice, with a 31-month interval. After revision of the occluded shunt failed, direct cavoportal puncture at the retrohepatic segment of the IVC was attempted. RESULTS: Transcaval TIPS placement was technically successful in all cases. In three, tractography revealed slight leakage of contrast materials into hepatic subcapsular or subdiaphragmatic pericaval space. There was no evidence of propagation of extravasated contrast materials through the retroperitoneal space or spillage into the peritoneal space. After the tract was dilated by a bare stent, no patient experienced trans-stent bleeding and no serious procedure-related complications occurred. After successful shunt creation, variceal bleeding ceased in all patients. CONCLUSION: Transcaval TIPS placement is an effective and safe alternative treatment in patients with occluded previous TIPS and no hepatic veins suitable for new TIPS.

Aggressive angiomyxoma is an uncommon mesenchymal myxoid tumor that is characterized by slow growth and frequent local recurrence. It is currently regarded as a nonmetastasizing tumor. We describe a case of recurrent aggressive angiomyxoma with invasion into the veins including the inferior vena cava and the right atrium and with pulmonary metastases. Our case, together with those unusual cases documented in previous reports, may lead to a reappraisal of the nature of aggressive angiomyxoma.

OBJECTIVEDue to its minimal-invasive approach, endovascular procedure had replaced surgery in treating Budd-Chiari syndrome (BCS). The interventional therapy was a safe and effective treatment in adults with BCS and the cure rate was high. However Budd-Chiari syndrome in children and adolescents is rare. Published literature on interventional procedure for Budd-Chiari syndrome in children and adolescents is scarce. The aim of the study was to present results of percutaneous transluminal angioplasty (PTA) and stents placement in children and adolescents with BCS and to evaluate the efficacy and safety in these patients of this approach.

METHODTwenty-five patients [16 boys and 9 girls; average age of (14.5 ± 3.4) years old; age ranged from 5 to 17 years] with Budd-Chiari syndrome who were hospitalized from December 1990 to August 2012 were presented. All of them were diagnosed by color Doppler ultrasound scan while 12 of them had magnetic resonance venography (MRV) scan. All of the patients had undergone angiographic examination. Four cases with membranous obstruction of the inferior vena cava (IVC) were treated with PTA. One case with segmental block of IVC was treated with PTA and stent placement. Five cases with membranous obstruction of IVC and hepatic vein (/and accessory hepatic vein) were treated with PTA. Among 8 cases with membranous obstruction of hepatic veins, 6 cases were treated with PTA and the others with PTA and stent placement. Among 4 cases with blocks of 3 hepatic veins (HVs), one was treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement and the other one was unsuccessful. Three cases with obstruction of HV and accessory HV (AHV) were treated with PTA. Totally, 24 patients were treated with interventional approach and followed up.

RESULTThe procedure was successful in 24 patients. The involved veins (hepatic veins or IVC) were patented after interventional procedure. The pressure of hepatic vein was (42.1 ± 4.2) cm H2O (37-50 cm H2O) (1 cm H2O = 0.098 kPa) before the interventional therapy, while it was (17.3 ± 3.3) cm H2O (14-26 cm H2O) after it. The pressure of IVC was (30.6 ± 2.9) cm H2O (26-36 cm H2O) before the interventional therapy, while it was (18.8 ± 4.2) cm H2O (15-26 cm H2O) after it. The symptoms and signs vanished instantly after interventional procedure. There were no procedure-related complications. The rate of overall initial cure was 96%. The patients were followed up for a mean of 25.8 months (range 6 months to 8 years). Seven cases developed restenosis after first procedure. Five of them were treated with PTA, one with PTA plus catheter thrombolysis plus PTA, one with PTA and stent placement. All of the involved veins were patented again. Clinical symptoms were relieved. There were no procedure-related complications as well.

CONCLUSIONThe interventional procedure in children and adolescents with BCS is the same as in adults. Radiological therapeutic intervention is efficacious and safe in children and adolescents with BCS.
