Catheterization and angiography of the abdominal arteries in the guinea-pig.

The abdominal arterial anatomy of the guinea-pig was investigated by angiography and dissection. Normally, a coeliacomesenteric trunk was found, although various forms transitional to the hepatolienogastric trunk were found. Multiple renal arteries were common in comparison to other laboratory animals and to man. A technique for selective catheterization of the abdominal arteries is described.
