Purpose: This study aimed to evaluate the clinical outcomes of placing Viabahn stent grafts in visceral arterial injuries and identify the risk factors associated with stent graft occlusion.
Material And Method: This multicenter, retrospective study included 29 procedures performed on 26 patients who underwent Viabahn stent graft placement between December 2017 and November 2022. We evaluated technical and clinical success rates, periprocedural complications, and stent graft patency using contrast-enhanced computed tomography. We conducted univariate analysis to examine the risk factors associated with Viabahn stent graft occlusion.
Result: The technical success rate was 96.6% (28 of 29), and the clinical success rate was 86.2% (25 of 29). The periprocedural complication rate was 17.2% (5 of 29), consisting of 4 mild adverse events and 1 patient death. The stent graft patency rates at 1, 3, 6, 12, and 24 months were 85%, 84.2%, 77.8%, 66.7%, and 50%, respectively. Univariate analysis indicated significant correlations between the lack of antiplatelet medication ( = .00074) and SG oversize ≥ 20% ( = .047).
Conclusions: This trial demonstrated the safety and effectiveness of Viabahn stent graft placement for visceral arterial injuries with high patency rates. Additionally, this study identified the lack of antiplatelet treatment and Viabahn oversize ≥ 20% as significant risk factors for Viabahn stent graft blockage in visceral arterial injuries.

Endovascular treatment of postoperative aortic coarctation aneurysms-a single center experience.

Background: Formation of local type aortic aneurysm years after surgical repair of coarctation (CoA) occurs in 10% of patients independent of the surgical technique and is a potentially life-threatening condition if left untreated with a high risk of aortic rupture. Redo open surgery is associated with 14% in-hospital mortality and a high risk of complications. Endovascular treatment appears to be a feasible alternative with a high success rate and low morbidity and mortality, but data concerning long-term results is still mandatory.

Background: Endovascular abdominal aneurysm repair (EVAR) offers a less invasive approach to treating abdominal aortic aneurysms (AAA) compared to open repair. However, EVAR is associated with higher rates of reintervention. This study investigates the early and mid-term outcomes of patients who underwent late open conversion including aneurysmorrhaphy after EVAR at our institution.

Introduction: Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

Article Synopsis
- The study evaluates the safety and effectiveness of the Zenith Dissection Endovascular System (ZDES) against traditional stent grafts for repairing acute complicated Type B Aortic Dissection (AcTBAD).
- A retrospective analysis of 32 patients revealed that the ZDES group experienced fewer postoperative adverse events (12 vs. 37), demonstrating better outcomes in false lumen thrombosis at 6 months and lower 3-year mortality rates.
- Despite some patients needing secondary interventions in the ZDES cohort due to aortic growth, overall results suggest the ZDES may offer improved safety and efficacy compared to traditional methods.

Article Synopsis
- Utilization of cangrelor as a bridging therapy to cardiac surgery has been noted for stent placement, but less so for endovascular revascularization.
- The case involves a 47-year-old female with a significant arterial dissection requiring a Viabahn endoprosthesis and subsequent cardiac procedures.
- A combination of cangrelor, aspirin, and bivalirudin was employed to manage the patient’s coronary disease and ensure the effectiveness of the surgical intervention, showcasing a multi-disciplinary approach in complex cases.
