title: Management of 219 consecutive cases of postcatheterization pseudoaneurysm.
abstract: OBJECTIVE
  We attempted to evaluate nonsurgical methods of treating postcatheterization pseudoaneurysm.
  
  
  BACKGROUND
  The value of reapplication of a compression bandage, ultrasound-guided compression repair (UGCR) and awaiting spontaneous thrombosis in the treatment of postcatheterization pseudoaneurysms is unsettled.
  
  
  METHODS
  We followed a stepwise treatment strategy of primarily conservative management using 1) reapplication of a compression bandage, followed by 2) UGCR, if needed, and 3) observation of the natural course. Surgical repair was reserved for patients with a rapidly expanding or complicated lesion.
  
  
  RESULTS
  Reapplication of a compression bandage was performed in 128 patients and was successful in 32%. The success rate correlated inversely with anticoagulant therapy and the size of the aneurysm. In case of failure this pretreatment with a compression bandage significantly enhanced the success rate of subsequent UGCR (p = 0.04). UGCR was performed in 124 cases with a success rate of 84%. In 54 patients with a stable lesion, refraining from any (further) active measures resulted in spontaneous thrombosis of the aneurysm in 50 patients (93%) after 1 to 180 days (median 40 days). The course of the remaining four femoral artery aneurysms was uneventful. Definitive repair by operation or collagen plug implantation was required in only 20 patients (9%).
  
  
  CONCLUSIONS
  The first measure performed in the treatment of pseudoaneurysms should be reapplication of a compression bandage, followed, if necessary, by UGCR. After failure of UGCR, spontaneous healing occurs in the majority of patients. Operation can be reserved for progressive and complicated lesions.
