Open in a separate window OBJECTIVESThe objective of the study was to evaluate early and midterm outcomes after the frozen elephant trunk (FET) procedure with different proximal landing zones in patients with aortic dissection.METHODSForty-four patients with type A and type B aortic dissection that extended down to the abdominal aorta were enrolled in the study. All of the patients had the FET procedure. The patients were divided in 2 groups according to the level of the proximal landing zone: the zone 2 (Z2) group and zone 3 (Z3) group. Early and midterm outcomes including the false lumen (FL) thrombosis rate were monitored in both groups.RESULTSThe incidence of stroke, delirium and spinal cord ischaemia was 5.9% vs 3.7% (P = 0.533), 5.9% vs 7.4% (P = 0.903) and 5.9% vs 0 (P = 0.533) in the Z2 and Z3 groups, respectively. The 30-day mortality was 9.1% in both groups. The mean distal landing zone was T7.5 (T7; T9) in the Z2 group vs T9 (T8; T10) in the Z3 group (P = 0.668). The 2-year overall survival was 62.2% with no significant difference in the Z2 and Z3 groups (61.6% vs 64.2%; P = 0.940). There were no aortic-related deaths during the follow-up period. Freedom from reintervention at 24 months was 73% and was comparable between Z2 and Z3 (74.1% vs 91.7%; P = 0.123). The rate of early complete FL thrombosis was comparable in the Z2 and Z3 groups. By 24 months of observation in the Z3 group, the rate of complete FL thrombosis was significantly higher (60% vs 77%; P = 0.046).CONCLUSIONSNo statistically significant differences were observed between landing zones 2 and 3 during the FET procedure with regard to early outcomes. Proximalization of the FET was associated with a shorter FL thrombosis in the midterm follow-up period that affected the distal aortic reintervention rate.  相似文献

Objective

Endovascular stent-grafting provides an alternative treatment option for high-risk patients with ascending aortic disease. The feasibility of this approach has been demonstrated before. We assess the updated experience with ascending thoracic endovascular aortic repair and propose a modification of the landing zone classification based on the outcomes.

Methods

From 2006 to 2016, 39 patients deemed very high risk for open replacement underwent endovascular repair of ascending aorta for acute type A dissection (12, 31%), intramural hematoma (2, 5%), pseudoaneurysm (22, 56%), and chronic dissection suture line entry tear (3, 8%). Ascending thoracic endovascular aortic repair was performed in 36 patients. In 3 patients with pseudoaneurysm, occluder devices were used. Computed tomography imaging analysis was performed, and the extent of aortic pathology was designated by segmental proximity to the left ventricle. Segmental anatomy of the proximal aorta was designed as zone 0A from the annulus to the distal margin of highest coronary, 0B extends from above the coronary to the distal margin of right pulmonary artery, and 0C extends from the right pulmonary artery border to the innominate artery. Multivariable time to event Cox regression analysis was performed to predict mortality, and long-term survival was estimated using the Kaplan–Meier method.

Results

Operative mortality was 13%; all 5 deaths occurred after emergency ascending thoracic endovascular aortic repair for type A dissection. Other complications included stroke in 4 patients (10%), myocardial infarction in 2 patients (5%), tracheostomy in 2 patients (5%), and dialysis in 2 patients (5%). In patients with acute type A dissection, the ascending pathology extended into zone 0A in 10 (71%) and 0B in 4 (29%). Among those with pseudoaneurysm, the location of the defect was in 0B in 11 (50%), 0C in 10 (45%), and 0A in 1. Among the patients with chronic dissection, the defect was located in 0C in all 3 (100%). After multivariable adjustment, Cox regression predicted significantly higher hazard of mortality with disease involving zone 0A versus 0C (P = .020) and older age (P = .026). Kaplan–Meier estimate of survival was also significantly worse in patients with disease extension into 0A versus 0C (P = .0018). At 30 days, 1 year, and 5 years, the overall survival was 81%, 74%, and 64% and freedom from reintervention was 85%, 77%, and 68%, respectively.

Conclusions

The modified zone zero classification is useful for characterizing extent of ascending aortic pathology and assessing prognosis. Location of the defect varies by pathology, and the presence of 0A disease predicts worse outcomes. Design of endovascular devices should be tailored to the aortic pathology and zone characteristics.  相似文献

Background

The general goals of endovascular management in chronic distal thoracic aortic dissection are optimizing the true lumen, maintaining branch patency, and promoting false lumen (FL) thrombosis. Distal seal can be challenging in chronic distal thoracic aortic dissection due to the well-established secondary fenestrations and fibrotic septum. We describe our approach of distal landing zone optimization (DLZO) to enable full-diameter contact of the distal endoprosthesis.

Materials and Methods

Our experience includes 19 procedures in 16 patients (12 male, age 68 ± 8 years) between May 2014 and November 2017. A history of previous ascending repair for type A dissection was present in 8 patients. Treatment indication was enlarging aneurysm in all subjects, and 4 patients had associated chronic visceral or distal ischemia. Point septal fenestrations were expanded by serial balloon dilation and/or wire-pull approaches. Balloon molding was used to ensure complete endograft apposition and FL collapse.

Results

One death occurred due to aortic perforation during wire-pull fenestration in a patient with heavily calcified and angulated aorta. The remaining procedures were accomplished safely and successfully. Balloon fenestration was used in 16 procedures, alone or in combination with a limited wire pull component. Adjunct procedures for distal seal included surgeon-modified fenestrated stent graft (3), iliac branch device (3), parallel superior mesenteric artery stent-graft (1), renal artery or superior mesenteric artery stent-graft (4), iliac stent (3), and plug obliteration of FL (5). Reintervention was required in 3 patients due to delayed loss of seal after the initial procedure (3, 8, and 12 months). Two were managed by repeat DLZO and distal extension. The third had distal extension via a surgeon-modified fenestrated stent-graft component. Follow-up imaging was available in 14 patients (16.0 ± 12.5 months, range: 1-33), with stable or regressed sac diameter with complete or near-complete thrombosis of the FL in all patients.

Conclusions

DLZO enabled creation of a distal seal zone in all patients. Residual retrograde filling of the FL is a marker of procedure failure, especially when seal segment length or feasible endoprosthesis oversizing are marginal. Insufficient landing segment can be circumvented with the use of a fenestrated or branched device to accomplish seal in the visceral aorta or iliac bifurcation. Adjunct FL ablation is also a valuable technique to promote FL thrombosis.  相似文献
