Initially, researchers believed the use of anticoagulant drug therapy would adversely affect the success rate of UGCR. However, studies have shown that UGCR can be successfully performed on patients who take anticoagulant drugs, as well as those who do not take them.[13-17,21] (See Table 1.) Again, compression times might be longer or second attempts may be needed, but success is possible.

(**) All unsuccessful UGCR patients were on heparin.
Although UGCR is feasible in most cases, there are situations where it should not be attempted.
Before beginning UGCR, a vascular surgeon should be made aware that the procedure is occurring, so that surgical intervention can take place if necessary.
In the absence of any of the indicated risk factors, it has been suggested that UGCR be attempted on all feasible PAs before taking a surgical approach.[1,24,26] Even if UGCR is unsuccessful or complications occur, subsequent surgical intervention would not be compromised.
