Combining Transarterial Embolization and Percutaneous Cryoablation for Early-Stage Renal Cell Carcinoma: Embolization Materials and Impacts of Tumor Size.

Background/objectives: Our aim was to compare the complication rates of different embolization materials (absolute ethanol and gelatin sponges) used for combined transarterial embolization (TAE) and to investigate the impact of tumor size on operative time and cryoneedle use during percutaneous cryoablation (PCA).

Methods: We treated 27 patients (9 women and 18 men; mean age, 74 years) with 28 early-stage (T1a) renal cell carcinoma (RCC) lesions using combined TAE and PCA between September 2018 and January 2021. During TAE, 15 lesions in 14 patients were embolized using mixed absolute ethanol and iodized oil.

Multiple delayed-onset metachronous ileal stenoses after transcatheter arterial embolization using -butyl-2-cyanoacrylate for upper gastrointestinal bleeding: factors of complication and importance of plain CT evaluations.

A 63-year-old man underwent transcatheter arterial embolization (TAE) using a mixture of -butyl-2-cyanoacrylate (NBCA) and iodized oil to treat acute gastrointestinal (GI) bleeding. The procedure was initially successful; however, the patient developed ileus >1 month later and subsequently underwent several surgeries to treat the multiple metachronous ileal stenoses. The flux of a small amount of off-target glue was the primary cause of these complications.

Common and uncommon vascular injuries and endovascular treatment associated with pelvic blunt trauma: a real-world experience.

Pelvic fractures are common in cases of blunt trauma, which is strongly associated with mortality. Transcatheter arterial embolization is a fundamental treatment strategy for fatal arterial injuries caused by blunt pelvic trauma. However, vascular injuries due to blunt pelvic trauma can show various imaging findings other than arterial hemorrhage.

The use of viabahn VBX stent-grafts for the treatment of extrahepatic portal vein hemorrhage.

Percutaneous transhepatic stent-graft placement usually requires more than a 12 F sheath, which has a higher potential risk of peritoneal hemorrhage. A case of postoperative portal vein hemorrhage after pancreaticoduodenectomy treated using a Viabahn VBX balloon expanding stent-graft is described in this report. The stent-graft was delivered using an 8 F sheath through a transhepatic approach and deployed from the superior mesenteric vein to the main portal vein.
