Ultrasound-accelerated versus standard catheter-directed thrombolysis in 102 patients with acute and subacute limb ischemia.

Purpose: To compare the safety and efficacy of ultrasound-accelerated thrombolysis (UAT) and standard catheter-directed thrombolysis (CDT) in patients with acute and subacute limb ischemia.

Materials And Methods: Medical records of all patients treated with thrombolysis for acute and subacute limb ischemia between August 2005 and January 2012 were reviewed. Coprimary (increase in ankle-brachial index, degree of lysis) and secondary endpoints (technical success, distal embolization, bleeding complications, need for additional interventions) were assessed.

Embolization of nonliver visceral tumors.

Catheter-directed embolization of visceral tumors, with the exception of the liver, has received limited attention in the literature. The visceral arterial anatomy can be complex and its understanding is critical for procedure planning and limiting complications. Embolization of splenic neoplasms is exceedingly rare.
