[Factors related to the appearance of peripheral vascular complications after taneous cardiovascular interventions].
BACKGROUND
Percutaneous diagnostic and therapeutic cardiac catheterization procedures carries some risks, most of them related to the appearance of peripheral vascular complications. These complications imply additional treatments for the patient including vascular surgery, longer hospital stays and increased costs. Some clinical and procedural variables have been pointed out as independent predictors of appearance of vascular complications. Nevertheless, no information have been reported concerning to the influence of the experience of the cardiologist who performs the procedure or provides the local hemostasia and the rate of vascular complications.


OBJECTIVE
To characterise the type and incidence of peripheral vascular complications in patients undergoing a percutaneous cardiac procedure, to identify the predictors and to determine the influence of the professional experience and the complexity of the technique in the complications rate.


RESULTS
Within 1-year (1994 to 1995) period, 1,008 consecutive patients undergoing a percutaneous cardiovascular procedure (750 diagnostic and 258 therapeutic) were prospectively included. Seventy percent were male. Mean age was 63 +/- 2 years. A total of 55 vascular complications were demonstrated (5.6%): 36 (3.6%) hematomas, 14 (1.4%) pseudoaneurysms, 2 (0.2%) arteriovenous fistula, 2 (0.2%) episodes of limb ischemia and 1 (0.1%) retroperitoneal hematoma. Only 28 (2.8%) were severe complications. By multivariate analysis, only experience to perform hemostasis (OR: 3.36; 95% CI: 1.37-8.22), previous treatment with aspirin (OR: 2.69; 95% IC: 1.31-5.52), left femoral artery puncture (OR: 2.53; 95% IC: 1-1.02), sheath removal later than 60 minutes (OR: 1.02; 95% IC: 1.01-1.04) and hemostasis which lasted > 30 minutes (OR: 1.01; 95% IC: 1-1.02), were independent predictors of vascular complications.


CONCLUSIONS
Vascular complications rate after percutaneous cardiovascular procedures was low. Most of them associated to procedural variables and potentially avoidable, with promotion of a well planned policy of training in order to modify the factors involved.
