The management of peripheral vascular complications associated with the use of percutaneous suture-mediated closure...

The purpose of this study is to identify the peripheral vascular complications associated with the use of percutaneous suture-mediated closure (PSMC) devices and compare them with postcatheterization femoral artery complications not associated with PSMC devices.

This is a retrospective review of all patients admitted to the vascular surgery service at the Chattanooga Unit of the University of Tennessee Department of Surgery with a peripheral vascular complication after percutaneous femoral arteriotomy between July 1, 1998, and December 1, 1999. The complications followed the use of PSMC devices (group I, n = 11) and traditional compression therapy (group II, n = 14) to achieve arterial hemostasis. Group II was subdivided into patients who required operative intervention (group IIA, n = 8), and those who were treated without operation (group IIB, n = 6).

No significant difference was found between groups I and II with regard to age (P =.227), time to vascular surgery consultation (P =.987), or diagnostic versus therapeutic catheterization (P =.897). A significant difference was found with regard to mean pseudoaneurysm size (group I = 5.9 cm, group II 2.9 cm; P =.003). Ultrasound compression was successfully performed in 66.6% of group II patients, but no (0.0%) patient in group I responded to this therapy (P =.016). Groups I and IIA had a significant difference for mean estimated blood loss (group I = 377.2 mL, group II = 121.8 mL; P =.017) and requirement for transfusion (P =.013). More patients in group I required extensive surgical treatment (P =.007), with six of these patients requiring vein patch angioplasty during their treatment. More patients in group I also had infectious complications (n = 3) compared with group IIA (n = 1).

In comparison with complications that follow percutaneous arteriotomy when PSMC devices are not used for hemostasis: (1) pseudoaneurysms after the use of PSMC devices are larger and do not respond to ultrasound compression, (2) complications associated with PSMC devices result in more blood loss and increased need for transfusion and are more likely to require extensive operative procedures, and (3) arterial infections after the use of PSMC devices are more common and require aggressive surgical management.
