Initial Single-Center Experience with the Ovation Stent-Graft System in the Treatment of Abdominal Aortic Aneurysms: Application to Challenging Iliac Access Anatomies

Commentary: Transcaval Approach in the Management of a Type I Endoleak Associated With the Ovation Stent-Graft System

“…From a total of 428 patients included in the previously published series, 7,8,10,11,15-19 only 4 (0.9%) cases presented a type I endoleak, 7,18,19 of which 2 (0.45%) where type Ia 7,18 (Table 1). Of these 4 type I endoleaks, three were identified and managed during the initial EVAR procedure, whereas the fourth case 7 was discovered and treated at 12 months’ follow-up.…”

“…Experience with the use of the Ovation stent-graft is accumulating, with a number of publications reporting excellent technical success rates ranging between 97% and 100% for all 7,8,10,11,15 –18 but one 19 report (Table 1). In the Ovation global pivotal study, Mehta et al 10 reported successful implantation in 100% of patients; 50% of subjects were treated percutaneously, without any access failures, type I or III endoleak, stent-graft migration, explant, or aneurysm rupture.…”

Tips to Ensure Optimal Ring Apposition of the Ovation Stent Graft in Challenging Necks of Abdominal Aortic Aneurysms

“…The Ovation Abdominal Stent Graft system (Endologix, Irvine, CA) is a trimodular endoprosthesis introduced for endovascular repair of abdominal aortic aneurysms (AAAs). 1 This endograft dissociates the stages of sealing and fixation with the former being accomplished infrarenally by a pair of polymer-filled inflatable rings and the fixation achieved via a 35-mm-long suprarenal stent. 2 A network of compliant, inflatable sealing O-rings are filled with a low-viscosity radiopaque polymer during the endograft's deployment to the point of accommodating tightly to the luminal surface of the AAA neck, thus providing an effective, gasket-like sealing effect.…”

“…A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT duplex ultrasound scan (DUS). His medical history was significant for smoking, 3hypertension, hypercholesterolemia and previous laparoscopic cholecystectomy On 4. physical examination a pulsatile epigastric mass was evident; femoral and distal pulses 5were normally present on both sides.…”

“…Nowadays endovascular repair (EVAR) for abdominal aortic aneurysms (AAA) has 2 become the standard of practice, and a huge variety of endografts is now available to the 3 Vascular Physicians 1,2 . Among those, the Ovation StentGraft (Trivascular, Inc, Santa 4 Rosa, CA, USA) offers the lowest profile (14F introducer sheath) of any commercially 5 available endograft increasing the number of patients suitable for EVAR including those 6 with smaller and tortuous common iliac arteries (CIAs) 3,4 . Currently, Ovation StentGraft is 7 indicated for treatment of patients with AAA with a vascular morphology suitable for EVAR, 8…”
