Single-Center Experience in the Endovascular Management of the Combination of Isolated Common and Internal Iliac Artery Aneurysms

Objective: The combination of isolated common and internal iliac artery aneurysms (CIIAA) are rare, life-threatening, abnormal conditions with relatively complex treatment. This study aimed to evaluate the clinical characteristics and treatment outcomes of CIIAA.Methods: We retrospectively reviewed 26 patients with CIIAA consecutively treated between January 2010 and August 2020 at Peking Union Medical College Hospital. Demographic, clinical characteristic, treatment strategy and outcome data were collected and analyzed.Results: Twenty-six patients (24 men and 2 women) with a mean age of 70 years were included. There was a total of 72 aneurysms, and the mean diameters of the common iliac artery aneurysms (CIAA) and internal iliac artery aneurysms (IIAA) were 36 and 38 mm, respectively. Ten patients (38%) presented with bilateral CIAA and unilateral IIAA, and eight (31%) had CIAA with ipsilateral IIAA. All patients were treated with endovascular repair, and the overall primary technical success rate was 100%. The surgical techniques mainly included combined bifurcated stent grafting and embolization (n = 11), combined straight stent grafting and embolization (n = 8), and internal iliac artery (IIA) reconstruction (n = 7). There were no patient deaths or reintervention during hospitalization. The mean follow-up time was 43 months, and the patency rate of the stent was 96.2%. The overall reintervention rate was 7.7%. During the follow-up period, there were no aneurysm-related deaths.Conclusions: Endovascular repair involving stent graft placement, coil embolization and IIA revascularization is a safe and effective treatment for isolated CIIAA.

Objectives: The purpose of this paper is to report the different modalities for the treatment of isolated internal iliac artery aneurysms (IIIAA), as well as their outcomes. Methods: We performed a systematic review of the literature (database searched: PubMed, Web of Science, Scopus, Cochrane Library; last search: April 2020). We included articles reporting on the outcomes for IIIAA interventions comprising at least 5 patients. Studies were included when presenting extractable outcome data regarding intraoperative and/or early results. We performed meta-analyses of proportions for different outcomes, using random effects model. Results: Thirteen non-randomized studies were included (192 patients with 202 IIIAA). IIIAA were symptomatic in the 18.1% (95%CI 9.3-26.9; I2 54.46%, P = .019). Estimated mean IIIAA diameter was 46.28 mm (95%CI 39.72-52.85; I2 88.85%, P < .001). Open repair was performed in 21/202 cases. Endovascular treatments were: embolization (81/181), embolization and hypogastric artery coverage (79/181), hypogastric artery coverage by stent-grafting (15/181), stent-grafting in the hypogastric artery (6/181). Overall estimated technical success (TS) rate was 91.6% (95% CI 86.8-95.5; I2 45.82%, P = .031). TS rate was 94.5% for open surgery (95%CI 85.3-100; I2 0%, P = .907), and 89.7% for endovascular repair (95%CI 83.8-95.6; I2 55.43%, P = .006). Estimated overall 30-day mortality was 3.1% (95%CI 0.8-5.4; I2 0%, P = .969). Mortality rates after open surgery and endovascular repair were 8.2% (95%CI 3.4-19.8; I2 0%, P = .545) and 2.8% (95%CI 0.5-5.1; I2 0%, P = .994), respectively. Estimated mean follow-up was 32.63 months (95%CI 21.74-43.53; I2 94.45%, P < .001). During this timeframe, IIIAA exclusion was preserved in 92.8% of the patients (95%CI 89.3-96.2; I2 0%, P = .797). Buttock claudication occurred in 13.9% of the patients (95%CI 8.7-19.2; I2 0%, P = .622). Conclusions: IIIAA are frequently large, and symptomatic at presentation. Several treatments are proposed in literature, open and endovascular, both with good results. The endovascular treatment is the preferred method of treatment in literature, since it offers good short- to mid-term results and low early mortality. Buttock claudication after hypogastric artery exclusion is a common complication.

Purpose: To analyze the results of endovascular repair of common iliac artery (CIA) aneurysms without preemptive coil embolization of the internal iliac artery (IIA). Materials and Methods: Between January 2010 and July 2016, 79 patients (mean age 74.3±8.4 years; 76 men) underwent endovascular repair extending into the external iliac artery owing to a CIA aneurysm. The procedure was performed for a ruptured aneurysm in 22 (28%) patients. Eighty-one IIAs were intentionally covered. The median CIA diameter was 37 mm (range 20–90). The primary outcomes were the occurrence of type II endoleaks and the incidence of buttock claudication. Results: Five (6%) patients died within 30 days (4 with ruptured aneurysms and 1 elective case). Two type II endoleaks originating from a covered IIA were recorded; one required an endovascular intervention because of aneurysm growth. The other patient died of a rupture based on an additional type III endoleak. Mean follow-up was 37.6±26.3 months. Nineteen (26%) patients required a secondary intervention. Buttock claudication was reported in 21 (28%) of 74 patients and persisted after 1 year in 7. No severe ischemic complications as a result of IIA coverage were recorded, and no revascularization was required during follow-up. Conclusion: Treatment of CIA aneurysms by overstenting the IIA without preemptive coil embolization is safe and has a low risk of type II endoleak and aneurysm growth. Persisting buttock claudication is rare.
