Abstract:
Objective To evaluate the mid-and long-term results of chimney-endovascular aneurysm repair (Ch-EVAR) on efficacy and durability.Methods Data of abdominal aortic aneurysm (AAA) patients receiving Ch-EVAR were retrospectively collected and analyzed.Results From Jan 2011 to Dec 2016,21 patients received Ch-EVAR in our institution including 18 males and 3 females with the average age 74.0 ±6.31 years.One patient died and 20 patients were followed up for an mean period of 53.2 months.During EVAR procedures 14 patients received left renal artery chimney stents,6 patients had right renal artery chimney stents and one did bilateral renal artery chimney stents.Technical success was achieved in all patients (100％).Differences between preoperative and one-week postoperative value of serum creatinine (P =0.639) and estimated glomerular filtration rate (eGFR) (P =0.804) showed no statistical difference.The differences of maximum sac diameter between preoperiation (60.1 ± 13.1 mm) and follow-up (59.2 ± 13.5 mm) was not significant (P =0.826).Six patients died during follow-up and none was aortic events related.All chimney stents were patent.One patient developed late type Ⅱ endoleak and refused reintervention regardless of aneurysm expansion.Conclusion For short hostile neck AAA patients with considerable surgical risk Ch-EVAR may be an effective and durable alternative.
