ABSTRACT
BACKGROUND:
Coil embolization (CE) alone and stent-assisted coil embolization (SCE) are two major endovascular techniques to treat renal artery aneurysms (RAAs). This study aimed at providing safety and efficacy data of CE and SCE for RAAs.METHODS:
Between August 2015 and June 2019, 40 RAA patients treated with CE or SCE were included in the retrospective study. Patients' demographics, clinical manifestations, aneurysm characteristics, treatment strategies, and follow-up results were collected and analyzed.RESULTS:
There were 26 and 14 patients in the CE and SCE group, respectively. The mean aneurysm diameter was 2.5 ± 1.5 cm and 2.2 ± 0.8 cm (CE versus SCE, P = 0.52). The neck width of the aneurysm was 0.63 ± 0.37 cm and 1.07 ± 0.42 cm (CE versus SCE, P = 0.021). Technical success was achieved in 97.5% patients. No death or aneurysm rupture occurred. During the perioperative period, 12% and 7.1% patients suffered partial renal infarction (CE versus SCE, P = 0.45). The mean duration of follow-up was 8.8 ± 9.4 months and 16.1 ± 16.3 months (CE versus SCE, P = 0.158) by imaging and 20.8 ± 11.3 and 22.7 ± 16.5 months by visit/telephone (CE versus SCE, P = 0.703). During the follow-up, 17.4% patients in the CE group and 30.8% patients in the SCE group suffered partial renal infarction, while their overall renal function remained normal. In addition, there was no aneurysm recurrence, sac enlargement, or death in both groups.CONCLUSIONS:
Both CE and SCE were safe and effective to treat RAAs. In addition, SCE may prevent coil migration in the wide neck aneurysm in selected patients.
