Comparative StudyPreoperative evaluation of the entire hepatic vasculature in living liver donors with use of contrast-enhanced MR angiography and true fast imaging with steady-state precession.
To preoperatively assess the entire hepatic vasculature in living related liver donors with use of a combination of contrast material-enhanced magnetic resonance (MR) angiography and true fast imaging with steady-state precession (FISP). ⋯ Preoperative imaging with use of a combination of contrast-enhanced MR angiography and true FISP provides a comprehensive assessment of the entire hepatic vasculature in living liver donors.

Randomized Controlled Trial Comparative Study Clinical TrialLong-term results of ePTFE stent-graft versus angioplasty in the femoropopliteal artery: single center experience from a prospective, randomized trial.
To describe a single-center experience as part of a U.S. multicenter prospective randomized trial of PTA versus percutaneous transluminal angioplasty (PTA)- and ePTFE (expanded polytetrafluoroethylene)-covered endoprosthesis placement for the treatment of superficial femoral artery (SFA) and proximal popliteal artery stenoses and occlusions. ⋯ This single-center experience with placement of the Hemobahn endoprosthesis (W.L. Gore & Associates) in the SFA demonstrated a statistically significant improvement in both patency and clinical outcome compared with PTA alone.

Comparative StudyPregnancy outcomes after fallopian tube recanalization: oil-based versus water-soluble contrast agents.
To determine the pregnancy outcomes in patients undergoing fallopian tube recanalization (FTR) with use of oil-based versus water-soluble contrast agents. ⋯ The use of an oil-based agent had little effect on the rate of conception, but time to conception was reduced by more than 3 months.

Improvement of sonographic needle visibility in cirrhotic livers during transjugular intrahepatic portosystemic stent-shunt procedures with use of real-time compound imaging.
The visibility of a transjugular intrahepatic portosystemic stent-shunt (TIPS) puncture needle was assessed with use of real-time compound imaging and single-line ultrasonography (US). In vitro and in vivo, needle-tissue contrast was calculated. ⋯ Subjective evaluation during TIPS procedures in 10 patients proved that the needle tip was significantly better seen with compound imaging. Therefore, real-time compound imaging significantly improved contrast and subjective visibility of the needle.

Multicenter Study Clinical TrialTreatment of occluded central venous catheters with alteplase: results in 1,064 patients.
Thrombosis of central venous access devices (CVADs) is a relatively frequent complication. Alteplase (tissue plasminogen activator) has been used to salvage dysfunctional devices. The purpose of this study was to analyze the safety and efficacy of alteplase after administration of a maximum of two 2-mg/2-mL doses to thrombosed CVADs. ⋯ A regimen of as many as two 2-mg doses of alteplase is safe and effective for restoring flow to occluded central venous access devices.
