Case ReportsIntranodal lymphangiography: feasibility and preliminary experience in children.
To review an initial experience studying the lymphatic system using direct injection of ethiodized oil contrast medium into lymph nodes (ie, intranodal lymphangiography) in children with chylous disorders. ⋯ The simplified technique of injecting contrast medium into a lymph node to opacify the lymphatic system in children can be an alternative to the more elaborate conventional lymphangiography.

Multicenter StudyUse of a retrievable vena cava filter with low-intensity anticoagulation for prevention of pulmonary embolism in patients with cancer: an observational study in 106 cases.
To evaluate a retrievable inferior vena cava (IVC) filter in combination with low-intensity oral anticoagulation for prevention of pulmonary embolism (PE) in patients with malignancy complicated by thromboembolic disease. ⋯ In patients with malignancies complicated by venous thromboembolic disease, an IVC filter together with low-intensity anticoagulation may be a possible treatment strategy for PE prophylaxis. Controlled studies are warranted.

CT-guided navigation of percutaneous hepatic and renal radiofrequency ablation under high-frequency jet ventilation: feasibility study.
Computed tomography (CT)-guided navigation during percutaneous radiofrequency (RF) ablations of liver and kidney lesions is hampered by respiratory motion and time-dependent lesion conspicuity after contrast agent injection. Therefore, target immobilization by general anesthesia with high-frequency jet ventilation (HFJV) instead of conventional ventilation (CV) with repeated breath-holds may facilitate and speed up navigation of RF ablation probes. ⋯ Percutaneous CT-guided navigation of RF ablation probes under HFJV is feasible and safe. It might be advantageous for the treatment of complex kidney and liver tumors, allowing less irradiation exposure to the patient and the interventional radiologist.
