Radiologic placement of a low profile implantable venous access port in a pediatric population.
To evaluate the feasibility and complications of placement of a low-profile venous access port in the chest in children requiring long-term venous access. ⋯ Low-profile chest ports placed by interventional radiologists in the interventional radiology suite can be placed in children as safely as traditional chest ports placed in the operating room. The incidence of infection, venous thrombosis and aspiration occlusion is comparable to that of ports placed operatively.

rt-PA thrombolysis in acute thromboembolic upper-extremity arterial occlusion.
Retrospective analysis of the results of rt-PA thrombolysis in the treatment of acute thromboembolic occlusion of the upper limb. ⋯ Interventional rt-PA treatment of proximal upper-extremity arterial occlusions may be performed with comparable success rates to surgical embolectomy and without severe complications. For distal occlusions the results are inferior to the success rates obtained with surgery.

Case ReportsTemporary percutaneous aortic balloon occlusion to enhance fluid resuscitation prior to definitive embolization of posttraumatic liver hemorrhage.
We successfully stabilized severe hemorrhagic shock following traumatic liver injury by percutaneous transcarotid supraceliac aortic occlusion with a 5 Fr balloon catheter. Then we were able to perform transfemoral embolization therapy of the hepatic arterial bleeding source. Transient aortic occlusion using a balloon catheter appears to be a useful adjunct in select cases where stabilization of the patient is necessary to allow successful selective embolization of the bleeding source.
