Reduction of vascular complication rates from femoral artery access in contemporary women undergoing cardiac catheterization.

BACKGROUND

Femoral arterial access (FAA) during diagnostic coronary angiography (CAG) and percutaneous coronary interventions (PCI) are associated with several vascular complications (VC). VC rate in our experience a decade ago was 3.02% and higher in women (4.7% in women, and 1.67% in men, p < 0.0006), with an OR of 2.81 (95% CI: 1.51-5.22).

METHODS

Patients who underwent CAG and PCI utilizing FAA (n = 2617) were separated into Period 1 (2005 to 2008; 1970 patients; Male 1045; Female 925) and Period 2 (2016-2017; 647 patients; Male 357; Female 290). FA access was preceded by anatomic FA localization during Period 1 vs. additional fluoroscopic marking of femoral head during Period 2. Ultrasound guidance was not utilized during either period. VCs were defined as hematoma>3 cm, major bleeding requiring blood transfusion or hemoglobin drop >2 g, retroperitoneal bleed, pseudoaneurysm, AV fistula, arterial thrombosis, distal embolism, dissection, and transient limb ischemia.

RESULTS

Rate of VCs did not differ from Periods 1 to 2 (2.44% vs. 2.32%, p = 1.0). An elevated rate of VCs experienced by women in Period 1 (Female 3.68% vs. Male 1.34%, p < 0.05) is no longer noted in Period 2(Female 2.07% vs. Male 2.52%, p = 0.79). Vascular closure device (VCD) use was protective in both Periods 1 and 2.

CONCLUSIONS

The use of fluoroscopic marking of femoral head prior to access, smaller sheath size, and being a high femoral volume center may have contributed to the reduced incidence of VCs in women. VCD utilization is continuing to reduce VC rates in both men and women.
