This study was performed to determine the effects of anastomosis on the internal diameter and wall thickness of jugular vein. Tro shepherd dogs were used for this experiment. In dog 1, xylazine(2 mg/kg) and ketamine(5.5 mg/kg) were injected intramuscularly for induction followed by enflurane(3%) anesthesia. In dog 2, acepromazine(0.03 mg/kg) and ketamine(5 mg/kg) were injected intravenously for induction followed by enflurane(3%) anesthesia. The dogs were heparinized(1 mg/kg) for the prevention of thrombosis. After jugular vein was exposed by incision of left cervical area, two Johns Hopkins bulldog clamps were clamped. Jugular vein was cut between two clamps, and it was reanastomosed using 5-0 silk. Ultrasonography was done along the jugular vein on both sides of each dogs 21 days after anastomosis surgery. The internal diameter and circumference of the vein in the anastomosis area were markedly reduced with thickening of the vein wall, but no thrombi were observed.

Tumor thrombus in the portal vein without any liver parenchymal abnormality is extremely rare. In the liver, the primary tumor most frequently presenting with intravascular tumor thrombi is hepatocellular carcinoma and lymphoma is rarely considered. Even though thrombosis occurs quite often in lymphoma, cases of tumor thrombus are rare and cases of tumor thrombus in the portal vein are even rarer. Only four cases of lymphoma with portal vein tumor thrombosis have been reported to date and all cases were the result of direct extensions of a dominant nodal or extra-nodal mass. To our knowledge, there has been no report on diffuse large B-cell lymphoma (DLBCL) presenting only within the lumen of the portal vein and not intravascular B-cell lymphoma. We present the first case of DLBCL presenting only within the lumen of the portal vein in an immunocompetent patient.

This study was conducted to determine the effects of deep breathing exercise and ankle exercise on blood flow velocity in the femoral vein. Sixteen healthy male students were recruited from Yonsei University, at Wonju. The blood flow velocities in the femoral vein were measured under three different conditions: resting, deep breathing, and ankle exercise. All subjects were given a 5-minute relaxing time in supine position prior to the study. Using a doppler ultrasound with a 8 MHz probe, the peak blood flow velocities were collected in a twenty-second-period at each condition. The subjects took a rest in between trials for the blood flow to return to its resting levels. The result showed a significant difference in peak blood flow velocities under those three conditions (p<.001). The peak blood flow velocity was highest in ankle exercise condition. The peak blood velocity was significantly higher in deep breathing condition compared with the resting condition. As a result, it is revealed that not only the muscular contractions but also the deep breathing exercises induced facilitating effects of venous return. Either of the exercise methods can be recommended to prevent blood stasis in patients with risk of deep vein thrombosis after cardiac or lower extremity surgery.

Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case of a 44-year-old man who was referred for recurrent pulmonary thromboembolism. He showed no other symptoms or signs except shortness of breath. A popliteal venous aneurysm was diagnosed incidentally because the examinations were performed to detect a deep vein thrombosis in relationship to the patient's history of pulmonary thromboembolism. We report a case of surgical treatment for a popliteal venous aneurysm that was complicated by pulmonary thromboembolism.

Pulmonary thromboembolism originated mostly from the venous thrombus, especially deep vein thrombosis in the lower extremities, which migrated upward and lodged the pulmonary vasculatures, Massive pulmonary thromboembolism usually leads to in \ulcornerhospital mortality if the patient was not treated properly. Under the cardiopulmonary bypass, a 49-year old man was treated successfully by emergent pulmonary embolectomy of pulmonary thromboembolism, which originated from the deep vein thrombosis in the right leg. Ligation or filtering device insertion of the inferior vena cava was not performed. The patient’s postoperative course was uneventful and discharged on postoperative 15th day He continued to receive oral anticoagulation with aspirin and persantin, which had been started on the third postoperative day. And he was well till recent days through the outpatient follow-up. The clinical courses of this patient are described, and massive pulmonary embolism and its management are discussed.

Desmoplastic small round cell tumor (DSRCT) is a rare and aggressive malignancy common in young male patient. Typical imaging features of DSRCT include multiple soft tissue masses in the peritoneal cavity, omentum, or mesentery without an organ of origin. This report presents a rare manifestation of DSRCT revealing a solitary large retroperitoneal mass with hepatic metastasis and malignant portal vein thrombosis in 70-year-old women together with the review of literature. The tumor showed a hemorrhagic and necrotic mass with peripheral portion of T2 hypo-intensity and delayed enhancement that indicated desmoplastic stroma with dense cellularity.

A 32-year-old woman presented with cough and hemoptysis. The radiologic findings showed increased interstitial markings in the right lung, a slightly decreased lung volume in the RLL and a hypoplastic right pulmonary artery with collaterals in the mediastinum and subpleural area. The pulmonary angiography showed an abrupt occlusion of the right lower pulmonary artery. The echocardiographic findings indicated pulmonary hypertension. A doppler leg ultrasonograph disclosed that the left popliteal vein was occluded with collateral veins, not filling the defect in the venous lumen. The D-dimer increased 1.0 ug/ml. This condition was initially misdiagnosed as a congenital pulmonary artery agenesis. Finally, a chronic pulmonary thromboembolism with a deep vein thrombosis was confirmed.

In this study, the effects of vascular parameter changes and electrodes on VOP measurement based on IPG were simulated mathematically. For the evaluation of the effects of hemodynamic changes on VOP, a mathematical model, which consists of cardiovascular system model and venous occlusion model, was developed and the model solution representing the blood flow and pressure in measuring point was found by 2nd order Runge-Kutta method. And, with sensitivity coefficients obtained from finite element solution of electric field in measuring point, the effects of electrode system on measurement were evaluated. As increasing the resistance, the venous capacitance was not changed but the venous outflows were decreased and the decreased compliance reduced the venous capacitance. And, for several configurations of round electrodes and band electrodes, the sensitivity coefficients were computed using the electric field distribution along deep vein. In conclusion, the proposed mathematical cardiovascular model could be applied to the simulation study on the effects of hemodynamic parameters on DVT diagnosis with IPG. And, also the sensitivity coefficients could provide effective electrode configuration for exact measurement of VOP.

Purpose: Deep Vein Thrombosis (DVT) is the cause of fatal diseases such as pulmonary embolism, due to a prolonged immobility, surgery, paralysis, and injuries. This study aimed to develop an evidence-based practice guideline for DVT prevention and apply it to patients with surgery in diverse nursing sites in South Korea. Methods: A 24-staged processes of adaptation was carried out on the basis of "adaptation of nursing practical guidelines" developed by Gu et al., in 2012. Results: Developed nursing guidelines of DVT prevention are composed of 79 recommendations in 8 domains. The extent and ratings of each recommendation with its evidence were addressed along with the background information. Conclusion: The developed DVT prevention guideline is necessary to be added to the evidence-based practice guidelines for the fundamentals of nursing practice. The developed guideline is needed to be disseminated to diverse nursing clinical settings in order to prevent DVT and enhance the quality nursing care.
