Cook Petite Vital Port, adherence of tubing to the vessel wall leading to complications in explanting the device

21 May 2014

Medsafe has received several reports of complications occurring during the explanting of this type of device from patients at the conclusion of their treatment. The reports relate to the silicone tubing of the port adhering to the vessel wall by a calcium-like deposit.

Calcium-like deposits are a known potential complication associated with implanted ports and indwelling catheters. However, there has been an increase in the number of reports received by Medsafe recently.

As a result of the adherence the explanting surgeon may need to make an additional incision and perform a venous cut-down to free the tubing from the vessel. There are no reported complications for the patient during the time the port is in use. This particular device is used in children and small adults.
