Endograft limb occlusion and stenosis after ANCURE endovascular abdominal aneurysm repair

Abstract

Unsupported endografts are at risk for developing ELD. The use of stents for limb support at the time of the initial endograft implantation may prevent subsequent ELD and bears further study. Endograft limb occlusion usually presents with acute severe ischemic symptoms, and the failure of operative thrombectomy necessitates femorofemoral artery bypass grafting. Endograft limb stenosis is identified by means of CDU surveillance in the postoperative period. Prompt treatment with percutaneous transluminal angioplasty/stent yields satisfactory primary assisted patency. Intraoperative intravenous ultrasound scanning, oblique angiograms, pressure gradients, and completion angiography may be necessary to detect and treat ELD.

Decreased Ischemic Complications After Endovascular Aortic Aneurysm Repair With Newer Devices

“…5,8,[11][12][13] A review of the literature by Aljabri et al found the incidence of lower-extremity ischemia after EVAR to be 5.1% (range, 0.6%-9.9%). The same authors' case series demonstrated a 9.6% incidence of lower-extremity ischemia (4 limb occlusions and 1 atheroembolic event).…”

Erfahrungen und Ergebnisse mit der Endologix-Aortenstentprothese

“…Im Vergleich zu anderen "unibody"-Systemen ergaben sich bei dieser Aortenstentprothese niedrigere Schenkelverschlussraten [1,[5][6][7], welches sicherlich durch die Längsstabilität der Prothese bedingt ist aufgrund des durchgestenteten Designs. Warum die Schenkelverschlüsse im Beobachtungszeitraum nur linksseitig auftraten, kann letztendlich nicht geklärt werden.…”

“…Unsupported endografts at more risk for limb dysfunction but it can be seen in any limb. 15 Continue down the remainder of the native outflow arterial tree to the femoral arteries, noting any flow abnormalities that could be associated with iatrogenic injury associated with the use of the large introducers used in the placement of these devices. Such injuries can include intimal flaps, dissection, hematoma, pseudoaneurysm, and arterio–venous fistula.…”
