Abstract
BackgroundExternal wrapping is a surgical technique performed in patients with a dilated ascending aorta. The aim of this study is to present the mid-term results of wrapping of the dilated ascending aorta.Methods34 patients (mean age: 64.4 ± 10.8 years, 21 males) with a dilated ascending aorta were operated on at a single cardiac surgery center using a wrapping technique. The aortas were wrapped with 32–36 mm straight Dacron vascular prostheses. The aortic wall was not excised in any of the patients. Wrapping was performed concomitant to other cardiac surgery procedures in 30 patients (88 %), which involved surgery on the aortic valve in 28 patients (82 %).ResultsThe mean follow-up time was 19.5 ± 8.3 months (median: 18 months, range: 12–36 months). None of the patients died or had aortic complications during the hospital stay and the follow-up period. A rethoracotomy had to be performed due to excessive postoperative bleeding in two patients. One patient was diagnosed with a transient ischemic attack on the 4th postoperative day, while another had respiratory failure requiring prolonged intubation. No redilatation of the ascending aorta or dislocation of the wrap was noticed in any of the patients.ConclusionsAccording to our study, external wrapping of the ascending aorta has good short-term results and may be regarded as a safe surgical option for patients with a moderately dilated ascending aorta.
Highlights
External wrapping is a surgical technique performed in patients with a dilated ascending aorta
We present the results of the use of the wrapping technique without concomitant aortoplasty
Patients The study was approved by the Local Ethics Committee (No KB 791/2012). 34 patients with a nondissected dilated (>40 mm) ascending aorta were operated on using the wrapping technique
Summary
External wrapping is a surgical technique performed in patients with a dilated ascending aorta. The technique was used in vascular surgery to treat abdominal aortic aneurysms and first described in the early 50s [2]. This procedure leads to a reduction of the diameter of the vessel by applying a corset made of an artificial material, i.e. a Dacron vascular prosthesis. Most studies report the results of wrapping with concomitant aortoplasty, where the excessive aortic wall is either resected or plicated, followed by a reinforcement using an external material [9]. Isolated wrapping (without aortoplasty) is a procedure that is mainly utilized in patients
