The medical records of 7 patients who underwent percutaneous transparaumbilical embolization of spontaneous portosystemic shunts for treatment of hepatic encephalopathy (HE) were retrospectively reviewed. Technical success was achieved in 100% (7/7) of patients. Four patients had complete resolution and 3 had improvement of signs and symptoms of HE within 3 days after the procedure for a clinical success rate of 100% (7/7). New-onset esophageal varices, a major complication, occurred in 1 patient. No other major complications were encountered. HE recurred in 71.4% (5/7) of patients during a median follow-up period of 43 months (range, 4–111 months).
Purpose: To assess biopsy technique, technical success rate, and diagnostic yield of image-guided percutaneous biopsy of omental and mesenteric lesions.
Purpose: To evaluate image-guided bone biopsy for bone histomorphometry to assess osteoporosis in children with respect to safety and yield.
Purpose: To assess the long-term outcomes of covered retrievable self-expandable metallic stent (REMS) placement for recurrent benign urethral stricture and to compare the outcomes associated with 3 types of covered REMSs.
Purpose: To demonstrate a proof of concept of magnetic resonance (MR) coagulation, in which MR imaging scanner–induced radiofrequency (RF) heating at the end of an intracatheter long wire heats and coagulates a protein solution to effect a vascular repair by embolization.
Purpose: To assess clinical efficacy and safety of image-guided percutaneous radiofrequency (RF) ablation of central renal cell carcinoma with adjunctive pyeloperfusion.
Purpose: To test the hypothesis that computed tomography (CT)-guided bone marrow biopsy in patients with a platelet count between 20,000/uL and 50,000/uL is safe and that preprocedure platelet transfusion is unnecessary.
Purpose: To report the final analysis of the safety and efficacy of portal vein (PV) recanalization (PVR) and transjugular intrahepatic portosystemic shunt (TIPS) creation (PVR-TIPS) in patients with PV thrombosis (PVT) in need of liver transplantation.
Purpose: To assess the feasibility and safety of concomitant intra-articular (IA) knee injection of mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) under fluoroscopic guidance to treat patellofemoral osteoarthritis (OA).
Purpose: To prospectively compare 2 different types of percutaneous fluoroscopic gastrostomy procedures (pigtail-retained gastrostomy [PG] vs mushroom-retained gastrostomy [MG]).
Purpose: To determine treatment preferences among endovascular and medical physicians who manage acute submassive pulmonary embolism (PE).
Purpose: To evaluate 30-day safety and efficacy of superselective embolization for arterial upper gastrointestinal bleeding (UGIB) using N-butyl cyanoacrylate (NBCA).
Purpose: To prospectively assess feasibility, safety, and cytoreductive effect of transarterial chemoembolization on renal cell carcinoma (RCC) using drug-eluting embolic agent (DEE) saturated with doxorubicin compared with transarterial embolization (TAE).
Purpose: To evaluate oncologic outcomes and graft viability after percutaneous radiofrequency (RF) ablation of renal cell carcinoma (RCC) developing within renal transplant allografts.
Purpose: To assess feasibility, safety, and oncologic outcomes of cryoablation in treatment of renal cell carcinoma (RCC) with extension into adjacent renal sinus vein.
