Résumé
Technical intraoperative complications (TICs) may occur during standard endovascular repair (EVAR) with possible effects on the outcome. This study evaluates the early and midterm effects of TICs on EVARs. All EVARs (from 2012 to 2016) were analyzed to identify all TICs: (1) endoluminal defects (stenosis, dissection, rupture, compression of native arteries, or endograft); (2) type I-III endoleaks; (3) unplanned artery coverage; and (4) surgical access complications. Follow-up was performed by Doppler ultrasound/ontrast enhanced ultrasound/computed tomography scan at yearly intervals. The outcome was compared with that of uneventful cases (UCs) through Fisher's exact test and Kaplan-Maier curve. TICs occurred in 68 (18%) of 377 patients undergoing EVAR. Thirty-two endoluminal defects were relined endovascularly; 24 type I-III endoleaks were treated with cuff deployment/forced ballooning (23) and surgical conversion (1); 3 of 8 unplanned artery coverages were revascularized (2 renal and 1 hypogastric); 5 hypogastric coverages had an unsuccessful correction; and 4 access artery injuries were repaired. Although fluoroscopy time and contrast usage were significantly higher in the TIC group than those in the UC group (309 cases), 30-day outcome was similar for death (1.4% TIC vs 0% UC, P = 0.18), reintervention (0% TIC vs 0.3% UC, P = 1), type I-III endoleak (0% TIC vs 0.9% UC, P = 1), steno-occlusions (0% TIC vs 0.3% UC, P = 1), buttock claudication, and renal failure (0% in both groups). At 24 months, TIC and UC groups had similar survival (91.7 ± 8% vs 96.2 ± 2.1%, P = 0.5), freedom from reintervention (81.4 ± 9.9% vs 96 ± 2.2%, P = 0.49), overall complication rate (13.4 ± 7.6% vs 11.4 ± 3.5%, P = 0.49), type I-III endoleak (11.2 ± 7.5% vs 7 ± 2.9%, P = 0.8), buttock claudication (0% vs 2 ± 2% P = 0.6), and hemodialysis (0% in both). Midterm iliac leg occlusion was significantly higher in the TIC group (26.9 ± 12.3% vs 3 ± 2.1%, P = 0.01). TICs may affect several aspects during EVAR, leading to the necessity of adjunctive maneuvers, which have no impact on early outcome but may cause an increased rate of midterm iliac leg occlusion.

All EVARs (from 2012 to 2016) were analyzed to identify all TICs: (1) endoluminal defects (stenosis, dissection, rupture, compression of native arteries, or endograft); (2) type I-III endoleaks; (3) unplanned artery coverage; and (4) surgical access complications.

RESULTS
TICs occurred in 68 (18%) of 377 patients undergoing EVAR. Thirty-two endoluminal defects were relined endovascularly; 24 type I-III endoleaks were treated with cuff deployment/forced ballooning (23) and surgical conversion (1); 3 of 8 unplanned artery coverages were revascularized (2 renal and 1 hypogastric); 5 hypogastric coverages had an unsuccessful correction; and 4 access artery injuries were repaired. Although fluoroscopy time and contrast usage were significantly higher in the TIC group than those in the UC group (309 cases), 30-day outcome was similar for death (1.4% TIC vs 0% UC, P = 0.18), reintervention (0% TIC vs 0.3% UC, P = 1), type I-III endoleak (0% TIC vs 0.9% UC, P = 1), steno-occlusions (0% TIC vs 0.3% UC, P = 1), buttock claudication, and renal failure (0% in both groups). At 24 months, TIC and UC groups had similar survival (91.7 ± 8% vs 96.2 ± 2.1%, P = 0.5), freedom from reintervention (81.4 ± 9.9% vs 96 ± 2.2%, P = 0.49), overall complication rate (13.4 ± 7.6% vs 11.4 ± 3.5%, P = 0.49), type I-III endoleak (11.2 ± 7.5% vs 7 ± 2.9%, P = 0.8), buttock claudication (0% vs 2 ± 2% P = 0.6), and hemodialysis (0% in both). Midterm iliac leg occlusion was significantly higher in the TIC group (26.9 ± 12.3% vs 3 ± 2.1%, P = 0.01).
CONCLUSION
CONCLUSIONS
TICs may affect several aspects during EVAR, leading to the necessity of adjunctive maneuvers, which have no impact on early outcome but may cause an increased rate of midterm iliac leg occlusion.
