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.

A phase III, open-label, single-arm study of tenecteplase for restoration of function in dysfunctional central venous catheters.
To evaluate, in a phase III, single-arm study, the safety and efficacy of the thrombolytic agent tenecteplase in restoring function to dysfunctional central venous catheters (CVCs). ⋯ Consecutive administration of one or two doses of tenecteplase into CVCs showed efficacy in the restoration of catheter function in patients with dysfunctional CVCs.

Percutaneous vertebroplasty in very severe osteoporotic vertebral compression fractures: feasible and beneficial.
To assess clinical outcome and technical feasibility of percutaneous vertebroplasty (PVP) in 34 patients with 37 osteoporotic vertebral compression fractures (OVCFs) with vertebral body collapse to less than one-third of the original height, termed very severe osteoporotic vertebral compression fractures (vsOVCFs). ⋯ Patients with painful vsOVCFs can be treated with, and benefit from, PVP. Although technically more demanding and with a higher procedural risk (ie, more frequent necessity of placement of a second needle, higher leakage incidence, and greater leakage volumes), PVP is technically feasible and should not be withheld from these patients.

Preoperative sclerotherapy of facial venous malformations: impact on surgical parameters and long-term follow-up.
To analyze the operative benefit of preoperative sclerotherapy of facial venous malformations and assess long-term patient outcome. ⋯ Preoperative sclerotherapy of venous malformations was associated with less operative time per lesion volume and less operative blood loss per lesion volume. Long-term follow-up revealed a low need for retreatment.
