Randomized Controlled Study of an Absorbable Vena Cava Filter in a Porcine Model.

Purpose: To compare the safety and efficacy of an absorbable inferior vena cava (IVC) filter and a benchmark IVC filter in a porcine model.

Materials And Methods: A randomized controlled Good Laboratory Practice study was performed in Domestic Yorkshire cross swine. Sixteen swine were implanted with an absorbable IVC filter (test device; Adient Medical, Pearland, Texas); 8 were implanted with a benchmark metal IVC filter (control device; Cook Medical, Bloomington, Indiana).

Ultrasonographic detection of adrenal gland tumors in two ferrets.

Hyperadrenocorticism is recognized as a common medical condition in middle- to old-aged ferrets. Because diagnosis of adrenocortical tumors in ferrets, using results of adrenocorticotropic hormone stimulation or dexamethasone suppression tests, is unreliable, ultrasonography was used as an alternative to laparotomy for the detection of tumors in 2 ferrets. The diagnosis was confirmed by surgical excision and histologic examination of the adrenal gland.
