Photocurable extracellular matrix sealant for cessation of venous hemorrhage.

Hemorrhage is the second leading cause of death in patients under 46 years of age in the United States. Cessation of hemorrhage prevents hemorrhagic shock and tissue hypoxia. Controlling the bleed via direct pressure or tourniquet is often the first line of defense, but long-term care requires staples, hemostatic agents, or sealants that seal the vessel and restore blood flow.

Comparison of Fibered versus Nonfibered Coils for Venous Embolization in an Ovine Model.

Purpose: To compare nylon fibered (F) with nonfibered (NF) coils for embolization in an ovine venous model.

Materials And Methods: Four- to 8-mm-diameter, 0.035-inch F and NF coils were deployed in 24 veins in 6 sheep.

The cytologic and histologic diagnosis of ureteral fibroepithelial polyp in a dog.

A 6-year-old, intact male, brindled, 30-Lb English Bulldog presented to the Purdue University Veterinary Teaching Hospital with a recurrent history of hematuria, periuria, and lethargy that responded temporarily to antibiotic therapy. The work-up included a complete blood count, serum biochemical profile, complete urinalysis, diagnostic imaging (abdominal radiographs and ultrasound with contrast urography), and exploratory laparotomy. The diagnostic imaging findings and subsequent exploratory revealed a unilateral, intraluminal, right-sided, 3-cm ureteral mass extending from the proximal ureter into the renal pelvis.

Novel swine model of colonic diverticulosis.

The pathophysiology of colonic diverticulosis has not been completely understood. The development of appropriate animal models is essential to study diverticular disease. To date, no large animal models are available for this disease condition.
