A 3-year-old castrated male domestic ferret was evaluated for abdominal distention. Survey lateral and dorsoventral abdominal radiographs were made. There were two soft tissue radiopacities consistent with grossly enlarged kidneys displacing small bowel and colon cranially, ventrally and caudally. Abdominal ultrasound was performed and revealed bilateral perinephric pseudocysts and polycystic kidneys. The perinephric pseudocysts were found to be dilated renal capsules on exploratory surgery and were drained. On follow up examinations, the pseudocysts were drained by ultrasound-guided paracentesis. The perinephric cyst fluid was distinguished from urine by measuring creatinine concentration and plans were made to resect the renal capsules due to rapid re-accumulation of pseudocyst fluid. The ferret's condition deteriorated and euthanasia was performed. Post-mortem examination was declined by the owner. Perinephric pseudocysts are rare and this is the first published report in a ferret. Ultrasound examination is the most rapid, accurate and non-invasive method for diagnosis of perinephric pseudocysts.

Pressure dropped after balloons inflation, rose during infusion, and dropped again after infusion completion. The pressure plateau was lower in a segment with side branch than in an isolated segment. However, embolizing the side branch using n-BCA immediately enhanced pressure plateau. The enhancing effect of embolization appeared to be more drastic with n-BCA than microcoils.The pressure plateau and time to reach plateau were affected by the infusion rate but less affected by the length of the occluded segment. Conclusions: TAMP is currently used in patients and the pig model further validated this novel local delivery mechanism of chemotherapy to solid tumors. The infusion rate and side branch exclusion have the biggest impacts on intravascular pressure. Segment with side branch can be embolized by n-BCA to achieve enhanced pressure gradient, comparable to segment without side branch.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
