Abstract
Objectives
Endovascular aneurysm repair (EVAR) is superior to open surgery repair (OSR) in multiple
aspects and is the mainstay for noninflammatory iliac artery aneurysm (IAA) treatment.
However, for noninflammatory IAAs with neighboring structures compressed, the experience
of endovascular treatment is limited. This case series study aimed to describe the
experience of EVAR of noninflammatory IAAs with urinary obstruction and to review
the limited reports in the literature.
Methods
From December 2012 to July 2020, we reported seven cases of noninflammatory IAAs combined
with urinary obstruction that were treated successfully with endovascular treatment.
The literature on noninflammatory IAAs combined with urinary obstruction was reviewed
using the online databases PubMed, Embase, and the Cochrane Library.
Results
Thirty-nine articles were found in the literature. OSR accounted for 80% of the treatment
options in previous publications, while only 20% of patients accepted endovascular
treatment. Hydronephrosis remission was observed in all patients treated by OSR, while
the endovascular treatment group lacked long-term follow-up. In our retrospective
study containing 7 cases, no complications, reintervention or mortality was observed,
all stents were patent, and all symptoms were relieved after the operation. Diameter
reduction of the aneurysms was observed in 6/7 cases, and the average aneurysm reduction
was -24.1±15.8 mm (P=0.0097). Urinary obstruction faded in 5/7 cases where aneurysm
shrinking was found simultaneously.
Conclusions
This case series and literature review on noninflammatory IAAs combined with urinary
obstruction suggests that the diameter of the responsible aneurysm may be reduced
after endovascular treatment, which may also alleviate symptoms of urinary obstruction
caused by noninflammatory IAAs.
