Vascular access ports (VPAs) are totally implantable devices designed to provide repeated access to the vascular system. Port access is performed by percutaneous needle insertion using a noncoring needle. VAPs have been placed in 12 dogs affected by different tumors and needing long lasting chemotherapy. Using the non-invasive Seldinger technique a silicone catheter was inserted from the jugular vein up to the junction of the cranial vena cava and the right atrium. The catheter then was connected to the port previously placed in a subcutaneous pocket over the scapula. 7/12 dogs showed no clinical complications. Port was removed in 4/12 dogs for post-operative complications as fistula formation (n.2) and infection/ mal-position (n.2). One patient had mild complications shortly after implantation. VPAs were left in site until the death in the rest of patients. VAPs are useful for dogs undergoing long-lasting chemotherapy protocols as these devices allow peripheral veins to be spared and not seriously damaged for repeated infusion of vesicant drugs. In most cases VPAs are well tolerated and may be left in site for several months.

Abstract

Vascular access ports (VPAs) are totally implantable devices designed to provide repeated access to the vascular system. Port access is performed by percutaneous needle insertion using a noncoring needle. VAPs have been placed in 12 dogs affected by different tumors and needing long lasting chemotherapy. Using the non-invasive Seldinger technique a silicone catheter was inserted from the jugular vein up to the junction of the cranial vena cava and the right atrium. The catheter then was connected to the port previously placed in a subcutaneous pocket over the scapula. 7/12 dogs showed no clinical complications. Port was removed in 4/12 dogs for post-operative complications as fistula formation (n.2) and infection/ mal-position (n.2). One patient had mild complications shortly after implantation. VPAs were left in site until the death in the rest of patients. VAPs are useful for dogs undergoing long-lasting chemotherapy protocols as these devices allow peripheral veins to be spared and not seriously damaged for repeated infusion of vesicant drugs. In most cases VPAs are well tolerated and may be left in site for several months.
