[Ultrasound-guided compression repair for iatrogenic femoral artery pseudoaneurysm].
OBJECTIVE
To evaluate relative factors affecting the efficiency of ultrasound-guided compression repair in iatrogenic femoral artery pseudoaneurysm.


METHODS
Ultrasound-guided manual compression was performed in 42 patients of iatrogenic femoral artery pseudoaneurysm from June 2004 to June 2010. There were 28 male and 14 female patients, with a mean age of (52 ± 5) years. These patients were presented with femoral artery pseudoaneurysm after catheterisation procedure by percutaneous femoral artery puncture and confirmed by color doppler flow image. Ultrasound-guided manual persistent compression with probe was performed at the puncture site between femoral artery and pseudoaneurysm, until completely thrombosis of pseudoaneurysm, whereas the pseudoaneurysm failed to complete closure required surgical repair.


RESULTS
Out of 42 patients, 34 patients (81.0%) were successfully treated by compression resulted in completely thrombosis. There were 8 (19.0%) failures conversion to surgery. Factors associated with success were size of pseudoaneurysm (< 25 mm, 25 - 40 mm, > 40 mm; χ(2) = 13.956, P = 0.001), anti-coagulation status (χ(2) = 5.578, P = 0.010), depth of artery break (< 50 mm, 50 - 80 mm, > 80 mm; χ(2) = 14.055, P = 0.001), pseudoaneurysm communicated with common femoral artery, superficial femoral artery and profunda femoral artery (χ(2) = 8.968, P = 0.011), as well as days to presented with pseudoaneurysm (< 3 d, ≥ 3 d; χ(2) = 5.733, P = 0.012). In multivariate Logistic regression analysis, success by compression was associated with size of pseudoaneurysm (WALD = 5.34, P = 0.021) and with depth of artery break (WALD = 4.84, P = 0.028).


CONCLUSIONS
The ultrasound-guided compression repair of iatrogenic femoral artery pseudoaneurysm is safe, convenient, inexpensive and reliable treatment.
