Thromboembolic Complications After Treatment with the INCRAFT AAA Ultra-Low-Profile Stent Graft System.

Type: article
Abstract: Objective Low-profile endografts have reported increased rates of limb graft occlusions. The INCRAFT stent graft system is an ultra-low profile endograft for the exclusion of infrarenal abdominal aortic aneurysms. Our aim was to report thromboembolic events (TE) in patients treated with the INCRAFT device and its association with risk factors.Methods A retrospective study was performed of 80 patients treated with the INCRAFT endograft between February 2015 and December 2022 at a single institution. All available imaging studies were reviewed by two reviewers independently. TE included intraprosthetic thrombus (IPT), limb graft occlusion (LGO) and distal embolization. A regression analysis was performed to evaluate possible risk factors associated with the development of TE. These included tortuous access vessels, IPT, access vessel diameter and the ratio between the cross-sectional area of the mainbody to the bilateral limb grafts.Results Limb occlusions occurred in 7 patients (9%) and 12 limbs (7.5%) resulting in a primary and secondary patency at one, three and five years of 96% and 99%, 94% and 97% and 89% and 93%, respectively. IPT was found in 36% of patients and affected endograft limbs in 93%. Ten distal occlusions in 8 patients (10.0%) were considered to origin from IPT, which led to symptomatic occlusions of below-the-knee vessels in all patients. Freedom from IPT at one, three and five years was 80%, 61%, and 43%, respectively. Age ≤70 years and access vessel diameter ≥10 mm were associated with IPT development. IPT was significantly associated with LGO (OR 77.10, p=0.003).Conclusion Thromboembolic events are frequent after treatment with the INCRAFT endograft with a limb graft occlusion rate of 9% per patient and IPT found in 36% of patients. IPT was more common in patients ≤70 years and was a significant risk factor for LGO.
