If the defect is repairable then suturing the vena cava (6-0 to 10-0 CV silk, or nylon, or prolene sutures) to repair the damage is the best option. As for things that can be used to help form blood clots gelfoam and/or surgicel can be used. For small defects direct pressure or topically apply a drop or 2 of epi to stop the bleeding. I have also tried Hemablock, but I did not like it. My other suggestion would be to have vascular clamps, so you can occlude the vena cava as you remove the right gland and repair the vena cava if necessary. Hope that helps, Jerry Murray, DVM [Posted in FML issue 4080]
