The obstruction of inferior vena cava(IVC) is uncommon condition. The classification is based on the obstructive sites of major anatomic segments of IVC. The main collateral pathways of interruption of IVC were central channels through ascending lumbar veins, intervertebral veins and azygos-hemiazygos complex. However, the complete obstruction of mid-portion of IVC, accompanying collateral cirulation with pericardiacophrenic vein was rarely reported. We had experienced a case of complete obstruction of mid-portion of IVC with lobulated left cardiac border, which was unforgettable characteristic finding on chest radiograph. It was confirmed by venographic examination that the lobulated left cardiac shadow was a collateral circulation of pericardiacophrenic vein.

A 5-year-old castrated male Golden Retriever dog weighing 15 kg presented with evidence of intestinal intussusception. The patient had cachexia and severe dehydration before being referred to our department. Ultrasound imaging revealed a target sign indicative of intestinal intussusception. Emergency surgery was performed shortly after diagnosis. After a successful surgery, the patient was hospitalised for postoperative care. Initial treatment was aimed at the reversion of dehydration and the provision of adequate nutrition. Fluid therapy and central parenteral nutrition were administered via the peripheral and central venous catheters, respectively. Ten days postoperatively, swelling and edema were observed in the head and neck. Ultrasound and computed tomography confirmed complete blockage of the cranial vena cava due to thrombosis, which consequently obstructed both the left and right jugular veins. For treatment, dalteparin and tissue plasminogen activator were administered. However, the patient lost all of its vital function on the daybreak of postoperative day 11. Venous thrombus formation secondary to central parenteral nutrition application via the central line is a rare but possible complication. Veterinarians who are concerned about taking care of patients receiving CPN through the central line should keep the possibility of venous thrombus formation in mind.

Seven patients [six women and one man] with obstruction of hepatic portion of inferior vena cava was operated on, from May, 1969 to January, 1985. Of seven patients, six were undergone corrective operation for IVC obstruction and another one was not operated because of far advanced liver cirrhosis. The occlusions were found at or close to the level of diaphragm and they were membranous or diffuse with or without thrombi. Most of their symptoms were referable to either inferior vena caval or hepatic venous obstruction and onset of the symptoms was usually gradual, beginning between the age of their thirties and forties. Most of the patients showed marked elevation of peripheral venous pressure of lower extremity [29-40 cm H2O] preoperatively, which decreased significantly after corrective operation [17-30 cm H2O]. Venous catheterization for pressure study and venography were essential for confirming the diagnosis. Of six cases, in which corrective operations were done, Transatrial membranotomy with or without IVC dilatation were performed in five cases [case 1, 2, 3, 5, 6], using cardiopulmonary bypass and in another one case, bypass operation between IVC, distal to obstruction, and RA was done using Dacron tube graft under the thoracoabdominal incision. All survived and their conditions were improved.

Massive air embolism during cardiopulmonary bypass is uncommon but serious and often lethal complication. Following this catastrophic event, the immediate institution of retrograde arterial blood perfusion via superior vena cava was made to remove air emboli from cerebral circulation. This method was performed by removing the arterial perfusion line from aortic cannula and connecting it to superior vena caval cannula. Then, retrograde perfusion at a flow rate of 2Umin via superior vena cava was carried out for 3 minutes. After air returning from the aortic cannula was identified, each line was connected to the cannulae primarily. In 2 cases who had massive air emboli due to air pumping into arterial line, the postoperative complete recovery resulted from this technique, which was used in conjunction with other therapy postoperatively.

A persistent left superior vena cava draining into the left atrium associated with atresia of the coronary sinus-ostium, ASD, and PDA is a rare congenital anomaly. The patient was a 4 year-old female whose complaints were frequent URI and exertional dyspnea. The congenital heart anomaly was suspected at 2 months of her age. Chest films showed cardiomegaly [C-T ratio, 75%]. EKG, Echocardiography, cardiac catheterization and angiocardiography were performed. Open heart surgery was done under impression of LV-RA shunt, bilateral superior vena cavae, and ASD. At the time of operation, huge LA and RA, inferior vena caval defect of a secundum type ASD [1.5 x 3cm in diameter], absence of innominate vein, atresia of the coronary sinus-ostium, and persistent LSVC draining into LA were noted. Direct suture closure of ASD and ligation of LSVC were done. The patient`s postoperative course was somewhat eventful: systolic murmur at apex remained. Four months after the operation, congestive heart failure attacked a few times. PDA that was overlooked at the time of open heart surgery was detected through postoperative cardiac catheterization in.4 months later. Emergent operation for closure of PDA was performed on the day of recatheterization. After that, patient`s heart failure was easily controlled without any notable problem.

This study was carried out to get fundamental information about the normal ultrasonogram of the liver and heart in Korean native cattle and calves. The interventricular septum, left ventricular internal diameter, left ventricular free wall thickness, aortic diameter, left atrial diameter, and right ventricular internal diameter of hear in 10 Korean native calves were determined at 4-5 right intercostal spare by use of ultrasonography. The caudal vena cava, portal vein, gallbladder, liver of 9 Korean native cattle and 10 calves were determined at 12, 11 and 10th intercostal spares by use of ultrasonography.

A 21 year-old male patient had a diagnosis of Budd-Chiari syndrome caused by inferior vena caval obstruction. Conservative medical therapy failed to control the symptoms of both portal hypertension and inferior vena caval stasis. Portocaval or mesocaval shunts may relive the symptoms of chronic forms of Budd-Chiari syndrome. But when inferior vena caval stenosis is severe, another procedure has to be used. Cavoatrial or portoatrial shunt has been suggested. Therefore, a long Dacron graft was placed from the inferior vena cava just below the left renal vein to the right atrium. He exhibited almost complete relief of symptoms for 1.5 year postoperatively. And there was angiographic proof of patency of the graft. This simple procedure should be encouraged in treatment of these patients.

We performed three replacement operations of great venous obstruction with Dacron prosthesis from July, 1980 to Nov. 1980. Summary of 3 cases as belows: 1) Inferior vena cava obstruction . 43 years old male was admitted because of abdominal distension and marked superficial collateral circulation on chest and abdomen. Inferior vena cavogram showed complete obstruction of I. V .C. just below hepatic vein. Bypass operation was done between Rt atrium '||'&'||' I. V.C. (just above renal vein) with Woven Dacron prosthesis (22mm in Diameter) under ex tracorporeal ci rculation. 2) Superior vena cava obstruction . 21 years old male was admitted because of facial edema and irritative cough. Well circumscribed lobulated mass was located at ant. superior mediastinum and extended to Rt. thorax in chest P-A view. Woven Dacron prosthesis (10mm in Diameter) was replaced at involved S.V.C. segment after Rt. upper '||'&'||' middle lobectomy with tumor resection. 3) Common iliac vein obstruction (Lt) . 64 years old female was admitted because of generalized edema and tenderness of Lt. lower extremity. Venography of Lt leg showed complete obstruction of common iliac vein. Woven Dacron prosthesis (10mm in Diameter) was replaced at obstruction site.eplaced at obstruction site.
