title: [Formation, therapy and prevention of false aneurysm of the femoral artery following diagnostic and interventional heart catheterization].
abstract: OBJECTIVE
  As pseudoaneurysm of the femoral artery after catheter introduction is a frequent complication, its causes and therapeutic options were investigated in a large patient collective.
  
  
  METHODS
  In a prospective study with colour-Doppler duplex sonography of 6928 patients after diagnostic and of 3764 after interventional cardiac catheterisation, pseudoaneurysms were diagnosed in 80 patients (0.75%), 46 after diagnostic (0.66%) and 34 after interventional (0.9%) catheterisation.
  
  
  RESULTS
  The incidence was higher in women than men (1.33% vs 0.58%; P < 0.05). Anticoagulation after sheath removal was the leading risk factor (n = 55, 68.8%), especially after interventional coronary intervention 85.3 vs 56.5%, P < 0.05). Local compression under duplex sonography monitoring was undertaken in 69 patients (86.3%), achieving aneurysmal obliteration in 53 (76.8%). Spontaneous thrombosis occurred in 15 of the remaining 27 patients, and surgical closure became necessary in 12.
  
  
  CONCLUSIONS
  These data indicate a risk profile for the occurrence of pseudoaneurysm after cardiac catheterisation which can be dealt with by preventive measures. Local compression under duplex sonographic monitoring was the treatment of choice with a high success rate and low incidence of complications.
