Abstract
OBJECTIVES
To evaluate the fate of perianeurysmal fibrosis (PF) following aneurysm surgery.
METHODS
In this single centre study, pre- and postoperative abdominal CT-scans on 21 consecutive patients with inflammatory abdominal aortic aneurysms were compared. CT-scans of 10 randomly chosen patients operated on for abdominal aortic aneurysms without PF in the same period, served as reference group.
RESULTS
Preoperative thickness of PF was assessed as > 1 cm in 11 and < 1 cm in 10 patients. Ureterolysis was performed in seven patients where the fibrosis caused ureteral obstruction. Postoperative CT-scans performed at a median of 24 (range 3-108) months after surgery showed complete regression of the fibrosis in 29%, partial regression in 57% and no change in 14% of the patients. Progression of the fibrosis or persistence of hydronephrosis was not seen. No sign of fibrosis were seen in the 10 controls.
CONCLUSION
This study supports the findings that PF tends to regress after repair of the abdominal aortic aneurysm.
