Objective: The aim of this retrospective single-center study was to assess the effectiveness and safety of Rotarex thrombectomy and angioplasty (balloon dilatation and stenting) in the treatment of aortic endograft occlusion (AEO) after the endovascular repair of abdominal aortic aneurysm (AAA). Methods: Among a total of 683 patients who underwent the endovascular aneurysm repair (EVAR) for AAA between May 2010 and March 2020, 46 (6.7%) patients developed occlusions of the aortic endograft; 16 patients were treated with fogarty embolectomy, 4 were treated with AngioJet aspiration, and 26 patients with mechanical thrombectomy (Rotarex system). The average time for AEO was 5 weeks (range 2-11 weeks). Immediately after angiography, Rotarex thrombectomy was used to remove the thrombus and embolus. After thrombectomy, balloon dilation was performed, followed by stent-graft deployment. The patients’ characteristics, treatment details, and outcomes were collected and analyzed. Results: There were 26 patients with AEO, 20 males (76.9%), and with the mean age of 67 ± 12 years (51-87). The primary reasons for AEO were kinking or extrinsic compression of the graft limb and thrombosis. The circulation was successfully restored in all patients by mechanical thrombectomy. Additional dilation/stents were required for 24 patients (93.3%), and they were placed in the graft limbs, thus re-establishing patency. The complications were observed in five patients and included peripheral embolization blue toe syndrome found in three patients and ischemia-reperfusion injury found in two patients. No mortality or recurrent thrombosis was observed in the follow-up period, which was extended for 12 months. Conclusions: The combination of Rotarex thrombectomy and angioplasty is a safe and effective treatment method for AEO after endovascular AAA repair.
