Purpose, To compare health-related quality of life outcomes in a cohort of
abdominal aortic aneurysm (AAA) patients treated concurrently with either a
conventional or endoluminal intervention.
Methods: Between December 1997 and April 1999, 51 AAA patients treated by e
ither open or endovascular techniques were enrolled in this prospective stu
dy. Conventional therapy was performed in 26 patients (19 men; mean age 70.
4 +/- 6.0 years) with anatomical features unsuitable for the endovascular a
pproach. Twenty-five patients (23 men; mean age 70.7 +/- 7.2 years) underwe
nt endoluminal AAA exclusion using either the Ancure or bifurcated Enduring
stent-grafts. The Medical Outcomes Study Short-Form 36-item health survey
was administered preoperatively and at 1, 4, 8, and greater than or equal t
o 52 weeks after discharge.
Results: At 1 week, both groups showed significant reductions (p < 0.001) i
n mean Scores compared to baseline in 4 dimensions (physical function, soci
al function, role-physical, and vitality), but the decline was more pronoun
ced in patients having open repair. Endoluminal patients returned to their
baseline scores by the 4th postoperative week, whereas complete recovery to
baseline in the conventional patients was delayed to the 8th week.
Conclusions: Patients treated endoluminally exhibit better physical and fun
ctional scores as early as 1 week after discharge; they also return to base
line status significantly earlier than the conventional group. These findin
gs document the perceived advantage of endovascular therapy over convention
al AAA treatment.
