title: Single-center experience with elective transcatheter coil embolization of splenic artery aneurysms: technique and midterm follow-up.
abstract: OBJECTIVE
  To review a single-center experience with elective coil embolization of splenic artery aneurysm (SAA) and analyze efficacy of the technique at midterm follow-up.
  
  
  METHODS
  From 2002 through 2011, 50 patients (28 women, 22 men; age range, 24-89 y; mean age, 53.5 y ± 13.6) underwent transcatheter coil embolization for treatment of SAAs. Pseudoaneurysms and ruptured aneurysms were excluded. A total of 63 SAAs were treated (size, 13-97 mm; mean, 29 mm). Ninety-eight percent of aneurysms were treated with coils alone. Regular follow-up consisted of an office visit and imaging. Patient medical records were reviewed for aneurysm location, procedural approach, and technical and clinical outcomes.
  
  
  RESULTS
  Ninety-eight percent of procedures were technically successful at thrombosing the aneurysm at the time of procedure. Repeat intervention was performed in four of 47 patients (9%) because of continued aneurysm perfusion at follow-up. Mean time to repeat intervention was 125 days (range, 42-245 d). All repeat interventions were technically successful. Neither aneurysm growth nor aneurysm rupture was observed in any patient during the follow-up period (mean, 78 weeks; range, 9 d to 7.1 y). There were no major adverse events. Major splenic infarction occurred in three of 33 patients (9%) with no underlying liver disease and normal splenic volume and in seven of 14 patients (50%) with portal hypertension.
  
  
  CONCLUSIONS
  Percutaneous transcatheter coil embolization is a safe, effective, and minimally invasive treatment for SAAs as evidenced by high rates of technical success and freedom from aneurysm rupture.
