ABSTRACT
INTRODUCTION:
This study aimed to assess the impact of urgency on early and midterm outcomes of the Candy-Plug (CP) technique for distal false lumen (FL) occlusion in thoracic endovascular aortic repair (TEVAR) for aortic dissection (AD).METHODS:
The CP registry was reviewed, and patients were categorized into elective and urgent/emergent groups for analysis. Endpoints included technical success, clinical success, early (30-day) computed tomography angiography (CTA) findings, early (30-day) mortality, adverse events, aortic remodeling in patients with available CTA follow-up and re-intervention.RESULTS:
A total of 155 patients received a custom-made Candy-Plug with 32 patients (44% males, mean age 61±9 years) were treated urgently vs. 123 patients (63% males, mean age 62±11 years) electively. The primary CP rate was higher in the urgent group; (28/32, (88%) in the urgent group vs. 96/123 (78%) in the elective group, p=051). The mean contrast volume was higher in the urgent group; (157±56ml in the urgent group vs. 130±71ml in the elective group, p=.017). Technical success was achieved in all patients in both groups. Clinical success was achieved in 25/32 (78%) patients in the urgent group vs. 113/123 (92%) in the elective group, p=.159. The early mortality rate was 4/32, (13%) patients in the urgent group vs. 1/123 (1%) in the elective group, p=.120). There was no statistically significant difference regarding the early adverse events between the urgent and elective CP groups. Early aortic-related re-interventions were required in 6/32 (19%) patients in the urgent group vs. 6/123 (5%) in the elective group, p=.094. Thoracic aortic aneurysm sac regression was lower in the urgent group (5/28, (18%) in the urgent group vs. 63/114 (55%) in the elective group, p=001). Stable thoracic aortic aneurysm sac was higher in the urgent group (22/28, (79%) in the urgent group vs. 47/114 (41%) in the elective group, p=000). An increase in thoracic aortic aneurysm sac occurred in 1/28 (4%) patient in the urgent group vs. 4/114 (4%) patients in the elective group, p=.096.CONCLUSION:
The urgent use of the CP technique for distal FL occlusion in AD was feasible and effective. The decrease in aortic FL sac diameter may be affected by the urgent use of CP due to limited sizing availability. However, it achieved high rate of aortic remodeling.
