Abstract
BACKGROUND
The introduction of cyanoacrylate (CA) within a blood vessel triggers polymerization, followed by an inflammatory reaction.
METHODS
A sheath was positioned 2.0 cm caudad to the junction of the superficial epigastric and abdominus rectus veins in 2 swine, followed by ultrasound-guided injection of 0.16 mL of CA glue. After glue delivery, the catheter was pulled back 3 cm, compression was applied to the treatment site, and the process was repeated for the entire length. At 60 days postimplantation, the veins were harvested surgically and examined histologically.
RESULTS
The histologic changes were consistent with a chronic foreign-body-type inflammatory response. Venous closure, segmental wall thickening, and fibrosis were observed.
CONCLUSION
Injection of CA is feasible for closure of superficial veins in animal models. Vein closure is achieved via an inflammatory process which ultimately leads to fibrosis.
