Imaging guidance with C-arm CT: prospective evaluation of its impact on patient radiation exposure during transhepatic arterial chemoembolization.
To prospectively evaluate the impact of C-arm CT on radiation exposure to hepatocellular carcinoma (HCC) patients treated by chemoembolization. ⋯ Routine use of C-arm CT can increase stochastic risk (DAP) but decrease deterministic risk (CD) from DSA. However, the increase in DAP is operator-dependent, thus, with experience, it can be reduced to under 10%. C-arm CT provides information not provided by DSA in 33% of patients, while decreasing the use of iodinated contrast medium. As with all radiation-emitting modalities, C-arm CT should be used judiciously.

A method for following patients with retrievable inferior vena cava filters: results and lessons learned from the first 1,100 patients.
Patients who have undergone implantation of a retrievable inferior vena cava (IVC) filter require continued follow-up to have the device removed when clinically appropriate and in a timely fashion to avoid potential long-term filter-related complications. The efficacy of a method for patient follow-up was evaluated based on a retrospective review of a single-institutional retrievable IVC filter experience. ⋯ The follow-up method described in the present study resulted in a statistically significant difference (P < .001) in the likelihood of a patient returning for IVC filter removal compared with a lack of follow-up (59% vs 24%).

Randomized Controlled Trial Comparative StudyConventional versus doxorubicin-eluting bead transarterial chemoembolization for hepatocellular carcinoma.
To compare short- and long-term clinical outcomes after conventional transarterial chemoembolization and drug-eluting bead (DEB) transarterial chemoembolization in hepatocellular carcinoma (HCC). ⋯ Conventional chemoembolization and DEB chemoembolization have a limited impact on liver function on short- and long-term follow-up and are associated with favorable clinical outcomes.

Multicenter StudyTraumatic occlusion and dissection of the main renal artery: endovascular treatment.
To report experience with endovascular treatment of traumatic injuries of the main renal artery. ⋯ The majority of occlusions and dissections of the main renal artery after major blunt abdominal trauma can be successfully treated with recanalization and stent placement. However, long-term kidney salvage is not always achieved, and there is a potential of development of renovascular hypertension, which may require late nephrectomy.
