To investigate the value of echocardiography in the diagnosis of total anomalous pulmonary venous connection (TAPVC), 16 patients in our hospital were diagnosed to have TAPVC by echocardiography from year 1994 to 2001. In 11 cases the results of echocardiography were compared to those of surgery. Each patient was examined by using a combination of precordial, suprasternal and subcostal windows to visualize all the pulmonary veins and their drainage sites, common pulmonary venous trunk, and other associated abnormalities. Of the 16 cases, the drainage sites were as follow: supracardiac in 10, via vertical vein in 9, directly to superior vena cava in 1; cardiac in 5, via coronary sinus in 2, directly to right atrium in 3. Diagnoses were correctly made in all the 11 cases as confirmed by surgery. Echocardiography can also assess pulmonary arterial pressure and detect other associated abnormalities. It is concluded that echocardiography is the preferred examination method in the diagnosis of TAPVC before surgery. With careful examination using multiple windows and sections, TAPVC can be accurately diagnosed by echocardiography.

Lemierre syndrome is a rare disease characterized by internal jugular vein thrombosis and septic emboli, and it primarily occurs in healthy young individuals; this disease usually follows an acute oropharyngeal infection. To the best of our knowledge, only a few reports about this disease have appeared in the radiologic literature. We report here the radiologic findings of a case of Lemierre syndrome in a young healthy female adolescent who had a history of acute pharyngotonsilitis. Chest radiographs showed lung nodules that displayed cavitary changes with rapid progression on the serial studies. High-resolution CT scan showed multi-focal patchy consolidations that connect with vessels, and this was suggestive of septic pulmonary embolism. Ultrasonography and CT scan of the neck revealed right internal jugular vein thrombosis.

PURPOSE: The incidence of thromboembolic episodes in children with nephrotic syndrome (NS) is low; however, these episodes are often severe. Moreover, both pulmonary thromboembolism (PTE) and renal vein thrombosis (RVT) rarely show clinical symptoms. This study was performed to determine the benefits of routine screening in the detection of thrombosis in childhood NS. METHODS: Among 62 children with nephrotic syndrome, a total of 54 children (43 males, 11 females) were included in this study. When the patients experienced their first NS episode, we performed renal Doppler ultrasonography in order to detect RVT. To rule out the possibility of PTE, a lung perfusion scan was performed. Computed tomographic (CT) pulmonary angiography was recommended to patients who showed possible signs of PTE. All patients were evaluated for clinical signs of thrombosis, biochemical indicators of renal disease, as well as clotting and thrombotic parameters. RESULTS: RVT or related clinical symptoms were not observed in any children. Based on the findings of the lung perfusion scans, 15 patients (27.8%) were observed with as a high probability of PTE. We were able to perform a CT pulmonary angiography only on 12 patients, and 5 patients were diagnosed with PTE (prevalence 8.1%). The serum fibrinogen level in the group with PTE was significantly higher (776.7+/-382.4 mg/dL, p<0.05) than that in the group without PTE, and other parameters were not significantly different between each group. CONCLUSION: Further studies are required for clarifying the role of renal Doppler ultrasonography for the detection of RVT in NS. Children with NS who developed non-specific respiratory symptoms should be evaluated for the diagnosis of PTE. In the management of NS, a lung perfusion scan should be performed at the time of the initial episode of NS regardless of the pulmonary symptoms, since patients having PTE are either often asymptomatic, or present with nonspecific symptoms.

Popliteal vein aneurysms (PVAs) represent a rare form of venous aneurysms and necessitate prompt management because of their well-established risk of pulmonary embolism (PE). Herein, we report a rare case of PVA without PE, successfully treated with open surgical repair. A 27-year-old man presented to our vascular clinic with chronic pain and swelling in his left lower limb. He had a long history of facial surgeries for the removal of congenital multiple osteomas. Physical examination revealed varicosities with an abnormal distribution. Duplex ultrasound showed a left PVA measuring 2.3 cm in diameter and 4 cm in length. Open surgical excision of the PVA with lateral venorrhaphy was performed through a medial approach. Prophylactic anticoagulation was performed postoperatively. In this case, the PVA was detected, with a high degree of suspicion by the clinician, before it caused fatal PE. The patient was successfully treated with aneurysm excision and lateral venorrhaphy.

OBJECTIVE: The purpose of this retrospective study was to evaluate the incidence of deep vein thrombosis (DVT) in spinal cord injury (SCI). METHOD: We analyzed the incidence of DVT and factors that alter its risk in 263 SCI patients. The injury status of each SCI subject was categorized as either motor complete or motor incomplete and either quadriplegic or paraplegic. The cause of injury was categorized as either traumatic or nontraumatic. Duplex ultrasound was performed in the clinically DVT suspected patients. No patient had been started on anticoagulant prophylaxis prior to diagnosis of DVT. RESULTS: Fifteen patients (5.7%) had a diagnosed DVT and one patient (0.4%) had a diagnosed pulmonary embolism. Motor complete lesion and quadriplegic status were better predictors of DVT than motor incomplete lesion and paraplegic status. Cause of injury and existence of spasticity were not statistically correlated with the incidence of DVT. Accuracy of clinical diagnosis was 45.4%. All cases of the diagnosed DVT was located proximal veins (iliac and femoral veins). Ten of 15 DVTs (66.6%) were detected earlier than 2 months after SCI. CONCLUSION: Incidence of DVT in SCI patients were 5.7%. Motor complete lesion and quadriplegic status were suggested as significant predictors of DVT in SCI patients.

PURPOSE: To identify risk factors for recurrent thromboembolic events (RTEs) and define the optimum duration of treatment with tinzaparin in patients with superficial vein thrombosis (SVT) of the lower limbs. MATERIALS AND METHODS: A total of 147 consecutive patients with significant SVT were treated with subcutaneously administered tinzaparin. The composite primary endpoint of the study was RTE, deep-vein thrombosis (DVT) and/or pulmonary embolism (PE) at 120 days. Patients were stratified into group A, where patients received a variable dose of tinzaparin for up to 60 days (n=98), and a subsequent group B-ext, where patients received a standardized intermediate dose of tinzaparin (n=49) for 90 days. RESULTS: RTEs occurred in 15/147 patients (10.2%), including recurrent SVT (n=10), DVT (n=4) and fatal PE (n=1). RTEs were less frequent in group B-ext (0% vs. 15.3% for group A, P=0.004), a difference that remained significant at the one-year follow-up. Clinically extensive SVT was an independent predictor for RTEs (hazard ratio, 5.94; 95% confidence interval, 2.05–17.23; P=0.001, Cox regression). Predictors or DVT or PE in group A included clinically extensive SVT (P=0.004), absence of local pain (P=0.023) and the ultrasound findings of superficial axial vein thrombosis (any, P=0.006 or isolated, P=0.036) and multiple thrombosed superficial venous sites (P < 0.001). CONCLUSION: An extended three-month regimen of tinzaparin in patients with SVT of the lower limbs is more effective than a shorter course and may be desirable in patients with risk factors.

A 29-year-old woman in her 8th week of pregnancy was referred to our hospital for swelling in the lower extremities, rapid onset of dyspnea (1 hr) and pre-syncope. Severe right ventricular dysfunction and moderate pulmonary hypertension were detected using 2-dimentional Doppler echocardiography. In addition, left calf vein and proximal thromboses were detected by venous compression ultrasound imaging. After successful thrombolytic treatment, the patient quickly recovered and was discharged from hospital on subcutaneous low-molecular-weight heparin. She delivered a normal, healthy infant at full-term (40 weeks).

Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.

An association between nephrotic syndrome and thromboembolic phenomena has been known for many years. Most common sites of venous throm-bosis in nephrotic syndrome are al vein and deep vein of lower extremity. We report a case of minimal change nephrotic syndrome associated with unusual extensive venous thrombosis. A 29-year-old man was transferred to our hospital with severe abdominal pain and ascites. 2 months before admission, he was diagnosed as minimal change nephropathy at another hospital and treated with steroid therapy but he had persistent proteinuria on admission. The abdominal ultrasonography and CT scan revealed diffuse thrombosis of left renal vein, splenic vein, superior mesenteric vein and portal vein. Deep vein thrombosis of lower extremity was also found but not pulmonary embolism. There was no evidence of other primary hypercoagulable disease. He was treated with intravenous heparin immediately and three days later, abdominal pain disappeared. Prednisolone and cyclophosphamide were administered as well. After 1 month of therapy, proteinuria was resolved. Abdominal CT scan, taken after 2 months of therapy, revealed that diffuse thrombosis were almost resolved. From this case, diffuse abdominal thrombosis should be included as a diffrential diagnosis in a nephrotic patient with abdominal pain.

Pulmonary embolism is most commonly related to deep vein thrombosis of the lower extremities. However, recent studies show that the thrombosis of superficial veins can also progress to deep vein thrombosis and pulmonary embolism. To our knowledge, there is no Korean report of pulmonary embolism associated with superficial vein thrombosis. We experienced an 82-year-old woman complaining of dyspnea and chest pain. On chest dynamic computed tomography (CT), pulmonary embolism was diagnosed. To evaluate the origin of the pulmonary embolism, abdominal CT, Doppler ultrasonography, and ascending venography of both lower extremities were done. We found no deep vein thrombosis, while thrombus of the proximal left greater saphenous vein was seen. We report a case of pulmonary embolism accompanying greater saphenous vein thrombosis without deep vein thrombosis.
