Endovascular Repair for a Ruptured AAA due to a Combined Type IIIb and Ia Endoleak.

We report a case of a ruptured abdominal aortic aneurysm (AAA) caused by a combined type IIIb and Ia endoleak. Also, we propose the mechanism that resulted in this combined endoleak. Specifically, a 71-year old-man, with a previous history of endovascular aneurysm repair (EVAR) for an AAA, was diagnosed with a contained rupture. CT scan depicted a type Ia endoleak and a migrated Talent endograft. A proximal aortic cuff sealed the endoleak, but intraoperative angiography revealed that a type IIIb endoleak coexisted due to fabric tear close to the Talent bifurcation. A second aortic cuff could not seal the fabric tear; so, in-lay parallel limbs were sequentially deployed as a "kissing endograft" technique inside the cuff. Simultaneous treatment of combined type IIIb and Ia endoleaks has not yet been described. Maybe the type IIIb endoleak is the primary entity causing sac enlargement, neck recontouring, proximal migration, and ultimately type Ia endoleak, which leads to huge enlargement and rupture. Placement of an aortic cuff to seal the proximal endoleak/migration and kissing endografts limbs for the fabric tear seems a safe option in such patients

DataSheet1_One-year outcomes following primary stenting of infrapopliteal steno-occlusive arterial disease using a non-polymer sirolimus-eluting stent: Results from a prospective single-centre cohort study.pdf

BackgroundClinical outcomes using new generation drug-eluting stents designed specifically for infrapopliteal disease are not widely available, especially in comparison to paclitaxel-based therapies. This series reports 1-year outcomes in patients with diabetes and chronic limb threatening ischaemia (CLTI) undergoing angioplasty, with a sirolimus-eluting tibial stent (Cre8, Alvimedica, Turkey), evaluating the feasibility, safety, and efficacy of this new device. Outcomes were compared to matched patients undergoing infrapopliteal angioplasty using a paclitaxel-coated balloon (DCB).Patients and MethodsPatients with diabetes and CLTI requiring infrapopliteal intervention were recruited prospectively to undergo angioplasty and primary stenting using the Cre8 sirolimus-eluting stent between January 2018 and October 2020 at a single high-volume vascular centre; outcomes were compared to a group of patients with diabetes and CLTI who had undergone infrapopliteal angioplasty using a DCB. All patients were followed up for at least 12 months using a uniform protocol with duplex ultrasound and examination. The primary outcome measure was target lesion patency (ResultsA total of 54 patients (61 target lesions; median age: 69 years, 74% male) were included [27 with the Cre8 device (main group) vs. 27 with a DCB (historical controls)]. Primary patency at 12 months was 81% in the Cre8 group vs. 71% in the control group (p = 0.498). Overall, four (15%) patients in the Cre8 group vs. three (11%) patients in the control group underwent a major amputation within 12 months (p = 1.0). CD-TLR (all endovascular) did not differ between groups at 12 months (4% Cre8 vs. 10% control group, p = 0.599). Rutherford stage improvement at 12 months was superior for the Cre8 group (52% vs. 15% improved by at least one stage, p = 0.039). One-year mortality was 15% in the Cre8 group vs. 22% in the control group, p = 0.726.ConclusionsPrimary stenting with the Cre8 stent is feasible and safe in diabetic patients and CLTI. When compared to patients undergoing angioplasty with a DCB, there were no significant differences regarding primary patency, CD-TLR, major amputations, and mortality at 12 months. Those treated with a Cre8 stent were more likely to have an improvement in their Rutherford stage.</p
