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.

Percutaneous embolization of iatrogenic arterial kidney injuries: safety, efficacy, and impact on blood pressure and renal function.
To evaluate the efficacy and safety of percutaneous renal artery embolization (RAE) of iatrogenic vascular kidney injuries and the effects of RAE on renal function and arterial blood pressure (BP). ⋯ Embolization of iatrogenic renal artery injuries is safe and associated with high technical and clinical success rates. It is not associated with a significant worsening of renal function or increase in BP.

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%).
