Project description:Background: This study employed three surgical techniques: total arch replacement (TAR) with frozen elephant trunk (FET), aortic balloon occlusion technique (ABO) and hybrid aortic arch repair (HAR) on patients with type I aortic dissection in Fuwai Hospital, aiming to compare the early outcomes of these surgical armamentariums. Methods: From January 2016 to December 2018, an overall 633 patients (431 of TAR+FET, 122 of HAR, and 80 of ABO) with type I aortic dissection were included in the study. Thirty-day mortality, stroke, paraplegia, re-exploration for bleeding, and renal replacement therapy were compared using the matching weight method (MWM). Results: After MWM process, the baseline characteristics were comparable among three TAR groups. It showed that ABO group had the longest cardiopulmonary bypass (p < 0.001) and aortic cross-clamp time (p < 0.001), while the operation time was longest in the HAR group (p = 0.039). There was no significant difference in 30-day mortality among groups (p = 0.783). Furthermore, the incidence of stroke (p = 0.679), paraplegia (p = 0.104), re-exploration for bleeding (p = 0.313), and CRRT (p = 0.834) demonstrated no significant difference. Of note, no significant differences were found regarding these outcomes even before using MWM. Conclusions: Based on the early outcomes, the three TAR approaches were equally applicable to type I aortic dissection. We may choose the specific procedure relatively flexibly according to patient status and surgeon's expertise. Importantly, long-term investigations are warranted to determine whether above approaches remain to be of equivalent efficacy and safety.

Project description:ObjectiveTo evaluate central aortic cannulation and arch branch vessel (ABV) cannulation in acute type A aortic dissection repair.MethodsFrom 2015 to April 2020, 298 patients underwent open repair of an acute type A aortic dissection. Patients undergoing femoral cannulation for cardiopulmonary bypass (n = 34) were excluded. Patients were then divided based on initial cannulation for cardiopulmonary bypass into central aortic cannulation (n = 72) and ABV cannulation (n = 192) groups. ABV sites included cannulation of the axillary, innominate, right/left common carotid, and intrathoracic right subclavian arteries.ResultsThe aortic cannulation group was younger (59 vs 62 years; P = .02), more likely to be men (76% vs 60%; P = .02), and had more peripheral vascular disease (60% vs 37%; P = .0009). ABV dissection was similar between central and ABV cannulation groups (53% vs 60%; P = .51). The aortic cannulation group underwent less aggressive arch replacement, had shorter cardiopulmonary bypass times (200 vs 222 minutes; P = .01), less utilization of antegrade cerebral perfusion (93% vs 98%; P = .04), and received less blood transfusion (0 vs 1 U; P = .001). Postoperative outcomes were similar between aortic and ABV cannulation groups, including stroke (5.6% vs 5.2%; P = 1.0) and operative mortality (4.2% vs 6.3%; P = .77). In addition, postoperative strokes were similar in location (right-brain, left-brain, or bilateral), etiology (embolic vs hemorrhagic), and presence of permanent deficits. Aortic cannulation was not a risk factor for postoperative stroke (odds ratio, 0.94; P = .91) or operative mortality (odds ratio, 0.70; P = .64). Short-term survival was similar between central and ABV cannulation groups.ConclusionsBoth aortic and ABV cannulation were safe and effective cannulation strategies in acute type A aortic dissection repair.

Project description:Total neointima implantation (patch neointima technique + triple-branched stent graft placement) has been performed in proximal aortic repair for acute type A aortic dissection (ATAAD) for more than 10 years at a center. However, there is no report on the mid-term outcomes with a control group of the surgical procedure. Consequently, the authors aimed to evaluate the safety and efficacy of this technique in this study. Patients who underwent the total neointima implantation were classified as Group A, and those who underwent the conventional aortic root reconstruction with the "sandwich" technique and the total aortic arch replacement were classified as Group B. Furthermore, the authors described the preoperative characteristics, operative data, and patient outcomes. Group A patients experienced a shorter surgery duration, lower volumes of perioperative bleeding, and fewer red blood cell transfusions. The incidence of neurological complications was significantly reduced in Group A. All patients maintained a normal range of proximal aortic sizes after surgery. Kaplan-Meier analysis revealed no significant differences between the patients in the two groups regarding cumulative mortality and the incidence of moderate-to-severe aortic insufficiency. In well-selected patients, total neointima implantation is an alternative procedure for the surgical repair of ATAAD.

Project description:BackgroundIn patients with acute acute type A aortic dissection (ATAAD) requiring emergency surgery, the use of aortic root repair or replacement remains a topic of controversy. The purpose of this study was to evaluate the early and mid-term clinical outcomes after aortic root repair or replacement, and to provide a theoretical basis for such patients.MethodsThe study included 442 consecutive patients with ATAAD who underwent aortic root repair [n=227, repair group (RG)] or the Bentall procedure [n=215, Bentall group (BG)] at our hospital between December 2018 and December 2021. The indications for aortic root replacement were aortic root sinus diameter of ≥4.5 cm, severe sinotubular junction involvement, unrepairable aortic valvulopathy, severe coronary ostium involvement, connective tissue disease, intimal tear at the aortic root, or dissection involving three aortic sinuses. The primary outcome was the survival rate and incidence of reoperation between the two groups.ResultsThe in-hospital and 30-day mortality rates in the RG and BG were 10.1% and 11.6%, respectively. The two groups had no significant difference (P=0.613). Multivariate logistic analysis showed that aortic root surgery did not influence the in-hospital or 30-day mortality rates. The mean follow-up time was 36.8±11.6 months (median, 33.4 months; interquartile range, 27.0-45.2 months). The 5-year survival rates for the RG and BG were 88.1% and 85.9%, respectively (P=0.650). During the follow-up period, only one patient in the BG group underwent proximal aortic reoperation.ConclusionsContinuous improvement of aortic root repair technology and identification of its indications may help reduce reoperation rates. Aortic root repair can be considered safe and feasible.

Project description:BackgroundThe management of acute type A aortic dissection (ATAAD) using the Ascyrus Medical Dissection Stent (AMDS) can lead to complications due to the persistence of the false lumen (FL). This case report presents two instances of failed AMDS treatment for ATAAD, highlighting the novel use of a trifurcated hybrid prosthesis for redo aortic arch repair using a minimally invasive frozen elephant trunk (FET) technique.Case presentationCase 1: A 57-year-old male, previously treated with AMDS for ATAAD, presented with an enlarging aortic arch and persistent FL two years post-surgery caused by re-entry in the distal aortic arch. Redo surgery using the FET technique with an E-vita OPEN NEO Trifurcated hybrid prosthesis resulted in successful repair and partial FL thrombosis. Case 2: A 51-year-old male with prior AMDS treatment for ATAAD presented with severe aortic valve regurgitation and a maintained FL perfusion due to a residual re-entry in the proximal region of the descending aorta. Redo surgery using the FET technique with the same hybrid prosthesis led to successful repair and good recovery, confirmed by follow-up imaging.ConclusionsThe use of the E-vita OPEN NEO Trifurcated hybrid prosthesis in the FET technique offers a promising solution for redo aortic arch repair in cases of failed AMDS treatment for ATAAD. This approach can improve patient outcomes by addressing complications associated with persistent FL and enhancing long-term survival.

Project description:BackgroundIt is controversial if the type or the size of aortic dissection is associated with the mortality in patients with acute aortic dissection (AAD) type I or type II according to DeBakey. Due to the pronounced aortic pathology in DeBakey type I compared to DeBakey type II, it is to be expected, that the DeBakey type I is associated with a significant higher morbidity and mortality. But we hypothesize that the current advances in surgical techniques, circulatory management, and postoperative care improve the clinical outcome of patients with DeBakey type I and II. The purpose of this study was to evaluate retrospectively the effect of these parameters on surgical outcome in patients with DeBakey type I and type II in a large cohort study.MethodsFrom 2001 to 2019, 395 consecutive patients (34.2% female) underwent surgical aortic repair at our institution. Patients were retrospectively classified into 2 groups: patients with type 1 dissection (group 1: n=309, median age of 62.0 years) and patients with type 2 dissection (group 2: n=86, 67.5 years). Survival was estimated by Kaplan-Meier estimator. Risk factors were analyzed by logistic regression analysis.ResultsThe patients in group 1 suffered significantly more often from coronary heart disease [43 (13.9%) vs. 20 (23.3%), P=0.036]. Otherwise, there were no significant differences between both groups concerning preoperative risk factors. The median surgical duration (279 vs. 263 min, P=0.026) and the circulatory arrest time (35 vs. 27 min, P<0.001) in group 1 were significantly higher. In a significantly higher number of patients in group 1, the aortic arch was completely replaced (18.4% vs. 1.2%, P<0.001) and a simultaneous coronary artery bypass grafting [18 (5.8%) vs. 11 (12.8%), P=0.028] was performed. The rate of re-thoracotomy [62 (20.1%) vs. 9 (10.5%), P=0.040], of postoperative delirium [66 (21.4%) vs. 9 (10.6%), P=0.024], and of tracheotomy [85 (27.5%) vs. 14 (16.3%), P=0.034] were significantly higher in group 1. Thirty-day mortality was 15.7% and did not differ significantly between both groups (P=0.867), as well as the long-term survival rates (P=0.956).ConclusionsDue to the pronounced aortic pathology in type I compared to type II, it is to be expected, that the type I is associated with a significant higher morbidity and mortality. DeBakey type I was an independent predictor for 30-day mortality in our study, however, based on our 17-year single center experience there was no difference between the long-term survival in both groups.

Project description:ObjectivesTo investigate the midterm results after zone 0 arch repair with frozen elephant trunks for acute type A aortic dissection.MethodsBetween October 2014 and April 2021, 196 patients underwent zone 0 arch repair with frozen elephant trunks for acute type A aortic dissection. The true lumen area, aortic lumen area, and false lumen status were assessed at four aortic levels, the proximal and distal descending thoracic aorta (level A and level B, respectively), celiac artery branching (level C), and terminal aorta (level D). Aortic remodeling (postoperative area as a percentage of the preoperative area) was classified into 3 groups, positive (true lumen area ≥120% with aortic lumen <120% or true lumen area ≥80% with aortic lumen <80%), minimal (80% ≤ true lumen area and aortic lumen area <120%), and negative remodeling (all other changes).ResultsIn-hospital mortality was 13 (6.6%) patients. The overall survival rate was 85.1% at 5 years. The freedom from distal aortic reintervention was 89.9% at 5 years. The prevalence of completely thrombosed or obliterated false lumen at 2 years was 96.8% at level A, 88.4% at level B, 47.2% at level C, and 27.6% at level D. The prevalence of positive aortic remodeling at 2 years was 84.7% at level A, 75.0% at level B, 29.2% at level C, and 16.7% at level D.ConclusionsZone 0 arch repair with frozen elephant trunks for acute type A aortic dissection can avoid invasive aortic arch resection and facilitate aortic remodeling of the descending thoracic aorta. The FET effect on aortic remodeling is limited at the aortic level below the FET stent end.

Project description:BackgroundThis study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease.MethodsThis retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.3 years; 90 males) performed from January 2009 to January 2019 at Beijing Anzhen Hospital. We analyzed 30-day and mid-term outcomes including survival rate and the incidence of stroke, spinal cord injury (SCI), and endoleak.ResultsFive deaths (4.6%) occurred within 30 days, including type I endoleak in Zone 1 (n=1), hemorrhagic shock (n=1), stroke (n=2), and stent migration (n=1). Two patients developed SCI. The median follow-up time was 39.5 (interquartile range, 13.6-69.0) months. In all, 14 late deaths occurred; these were due to stroke (n=2), severe pneumonia (n=1), aortic rupture caused by type I endoleak (n=3), and sudden death (n=8). Six late endoleaks occurred including three type I and one type II in Zone 1 and two type I in Zone 2. In a competing risks analysis, the incidences of reintervention at 7 years, late death, and survival without reintervention were 8%, 22%, and 70%, respectively. In a Cox risk model, stroke (HR, 21.602; 95% CI: 2.798-166.796; P=0.003) was the only risk factor for 30-day mortality. Stroke (HR, 19.484; 95% CI: 5.245-72.380; P<0.001), SCI (HR, 15.548; 95% CI: 2.754-87.786; P=0.002), and endoleak (HR, 4.626; 95% CI: 1.068-20.040; P=0.041) were independent risk factors for long-term mortality.ConclusionsThe one-stage hybrid procedure provides acceptable mid-term results with good mid-term patency of extra-anatomic bypass. Strict selection of patients suitable for hybrid repair can effectively improve the survival rate and reduce the incidence of complications. At the same time, close follow-up patients should receive close long-term follow-up after hybrid procedure.
