Objectives
Early experience with Loeys-Dietz syndrome (LDS) suggested an aggressive aortopathy with high risk of aneurysm dissection and rupture at young ages and at smaller aortic diameters than in other connective tissue disorders. We reviewed our experience with LDS to re-examine our indications and outcomes of surgical management.Methods
We reviewed all patients with a diagnosis of LDS who underwent cardiovascular surgery at our institution. The primary endpoint was mortality, and secondary endpoints included postoperative complications and need for reintervention.Results
Seventy-nine operated patients with LDS were identified. Mean age at first operation was 25 years, 39 (49%) were female, and 38 (48%) were children (age <18 years). Six (8%) patients presented with acute dissection. Five (6%) patients had a bicuspid aortic valve, and all presented with an ascending aortic aneurysm with a mean root diameter of 3.5cm. Twenty (25%) patients had a previous sternotomy. Sixty-five (82%) patients underwent aortic root replacement, of whom 52 underwent a valve-sparing operation and 4 had concomitant arch replacement. Mean aortic root diameter in this group was 4.2 cm. Nine (11%) patients underwent aortic arch replacement, 2 (3%) had isolated ascending aorta replacement, and 3 (4%) underwent open thoracoabdominal repair. There were 2 (3%) operative and 8 late deaths. Nineteen patients underwent subsequent operations for late aneurysm and/or dissection. Mean follow-up was 6 years (range 0-24 years). Kaplan-Meier survival was 88% at 10 years.Conclusions
Growing experience with LDS has confirmed early impressions of its aggressive nature and proclivity toward aortic catastrophe. Surgical outcomes are favorable, but reintervention rates are high. Meticulous follow-up with cardiovascular surveillance imaging remain important for management, particularly as clinical LDS subtypes are characterized and more tailored treatment is developed. 相似文献2.

Objectives
Endovascular aortic repair is increasingly being used to treat aneurysms, dissections, and traumatic injuries, despite its unknown long-term durability. We describe our 19-year experience with open descending thoracic and thoracoabdominal aortic repair after endovascular aortic repair.Methods
Between 1996 and 2015, 67 patients were treated with open distal arch, descending thoracic, or thoracoabdominal aortic repair, or extra-anatomic bypass repair with aortic extirpation for complications after endovascular repair of the thoracic (n = 45, 67%) or abdominal (n = 22, 33%) aorta. The median interval between procedures was 18.0 months (interquartile range, 3.9-44.9). Indications for open repair included expanding aneurysm (n = 56), infection (n = 11), fistula (n = 8), aneurysm rupture (n = 5), pseudoaneurysm (n = 2), and restenosis (n = 1). Open repair involved partial (n = 9, 13%) or complete (n = 56, 84%) device removal or device salvage (n = 2, 3%) through a thoracoabdominal (n = 58, 87%) or thoracotomy (n = 9, 13%) incision. Eight patients (12%) underwent emergency procedures.Results
There were 3 early (operative) deaths (2 with preoperative device infection) and 19 late deaths during a median follow-up of 35.8 months (interquartile range, 16.8-52.8 months). Overall 1- and 5-year survivals were 85% ± 4% and 60% ± 8%, respectively. Four patients had open repair failures necessitating reoperation; 2 patients had preoperative infection, and both died (1 early and 1 late).Conclusions
Open repair for complications after endovascular procedures is not uncommon. Experienced centers can yield acceptable outcomes, especially in patients without infection. Close surveillance is mandatory after endovascular aortic repair. 相似文献3.

Objective
To evaluate the impact of preoperative pulmonary function on outcomes after open repair of descending thoracic (DTA) and thoracoabdominal aortic (TAAA) aneurysms.Methods
The outcomes of patients undergoing open repair of DTA or TAAA were analyzed in relation to the results of preoperative pulmonary function tests. Receiver operating characteristic was adopted to assess the effect of forced expiratory volume in one second (FEV1) on the incidence of mortality. Logistic regression analysis and propensity score matching were used.Results
Between 1997 and 2015, 726 patients underwent open DTA or TAAA repair. Pulmonary function tests were available in 711 (97.9%). Receiver operating characteristic analysis revealed the cutoff value of FEV1 to be 50%. Propensity score matching led to 149 pairs of patients with FEV1 below and above 50% with only limited residual imbalance. In the matched population operative mortality was 11.4% and 6.0% in patients with FEV1 ≤ 50% and FEV1 ≥ 51%, respectively (P = .10). The incidence of major adverse events was 33.1% in cases with FEV1 ≤ 50% and 19.5% in those with FEV1 ≥ 51% (P = .008). FEV1 ≤ 50% was associated with a 6.99× increase in the risk of major postoperative adverse events at logistic regression analysis.Conclusions
Preoperative FEV1 < 50% is strongly predictive of increased respiratory failure, tracheostomy, and operative mortality in patients undergoing open DTA/TAAA repair. For these very high-risk patients with either extensive TAAAs or anatomy unsuitable for endovascular repair, medical therapy may offer the best long-term survival. 相似文献4.

ObjectiveTo evaluate the long-term incidence and outcome of aortic interventions for medically managed uncomplicated thoracic aortic dissections.MethodsBetween January 2012 and December 2018, 91 patients were discharged home with an uncomplicated, medically treated aortic dissection (involving the descending aorta with or without aortic arch involvement, no ascending involvement). After a median period of 4 (first quartile: 2, third quartile: 11) months, 30 patients (33%) required an aortic intervention. Patient characteristics, radiographic, treatment, and follow-up data were compared for patients with and without aortic interventions. A competing risk regression model was analyzed to identify independent predictors of aortic intervention and to predict the risk for intervention.ResultsPatients who underwent aortic interventions had significantly larger thoracic (P = .041) and abdominal (P = .015) aortic diameters, the dissection was significantly longer (P = .035), there were more communications between both lumina (P = .040), and the first communication was significantly closer to the left subclavian artery (P = .049). A descending thoracic aortic diameter exceeding 45 mm was predictive for an aortic intervention (P = .001; subdistribution hazard ratio: 3.51). The risk for aortic intervention was 27% ± 10% and 36% ± 11% after 1 and 3 years, respectively. Fourteen patients (47%) underwent thoracic endovascular aortic repair, 11 patients (37%) thoracic endovascular aortic repair and left carotid to subclavian bypass, 3 patients (10%) total arch replacement with the frozen elephant trunk technique, and 2 patients (7%) thoracoabdominal aortic replacement. We observed no in-hospital mortality.ConclusionsThe need for secondary aortic interventions in patients with initially medically managed, uncomplicated descending aortic dissections is substantial. The full spectrum of aortic treatment options (endovascular, hybrid, conventional open surgical) is required in these patients. 相似文献

ObjectiveWe present our open surgical strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome.MethodsBetween October 1999 and December 2017, 82 patients with Marfan syndrome underwent 118 aortic repairs. We divided the aorta into 4 segments for categorization: (1) the aortic root, (2) aortic arch, (3) descending thoracic, and (4) abdominal aorta. Procedures were categorized according to the types of surgery. Staged repair was defined as a subsequent operation on a different segment of the aorta after initial repair (n = 111, 94.1%), and reoperation was defined as an operation on the same segment (n = 7, 5.9%).ResultsThe mean age at initial operation was 41.7 ± 14.9 years. Staged repairs included aortic root replacement (n = 42, 36%), total arch replacement (n = 11, 9.3%), combined aortic root and total arch replacement (n = 13, 11%), descending aorta replacement (n = 4, 3.4%), thoracoabdominal aortic repair (n = 36, 31%), and extensive arch-descending or thoracoabdominal repair (n = 5, 4.2%). Four patients received 3 staged repairs. Operative mortality was 0.8% (1/118). Stroke occurred in 1.7% (2/118), and spinal cord injury occurred in 1.7% (2/117). Overall survival was 95.8 ± 2.4% at 10-years. Twenty-four patients underwent replacement of the whole aorta after 2.5 ± 3.8 years following initial repair.ConclusionsOur strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome resulted in excellent early- and long-term outcomes. 相似文献
