Objective: The aim of this study was to report outcomes of the BeGraft and BeGraft Plus as bridging covered stents in fenestrated and branched endovascular aneurysm repair (FB-EVAR).
Methods: Patients treated and followed in two institutions receiving at least one BeGraft or BeGraft Plus as bridging covered stent between January 2018 and July 2023 were included.
Results: A total of 765 target vessels (TVs) in 281 patients were aimed to be bridged with the BeGraft or BeGraft Plus. Target vessel technical success was 99.5% (761/765). Estimated TV patency at one and two years was 98.5 ± 0.5% and 96.7 ± 0.9%, respectively, with no difference between fenestrations and branches. Estimated freedom from TV related endoleak at one and two years was 98.5 ± 0.5% and 97.9 ± 0.6%, respectively. Estimated freedom from endoleak at two years was lower for TVs targeted with branches compared with TVs targeted with fenestrations (94.2 ± 1.9% vs. 99.7 ± 0.3%, respectively; p < .001). Estimated freedom from TV related re-intervention at one and two years was 97.7 ± 0.6% and 97.1 ± 0.7%, respectively. Estimated freedom from TV related re-intervention at two years was lower for TVs targeted with branches compared with TVs targeted with fenestrations (93.1 ± 2.0% vs. 99.0 ± 0.5%, respectively; p < .001). Estimated freedom from TV instability at one and two years was 96.8 ± 0.7% and 94.5 ± 1.1%, respectively. Estimated freedom from TV instability at two years was 96.0 ± 1.3% for fenestrations and 91.2 ± 2.2% for branches (p = .003).
Conclusion: The BeGraft and BeGraft Plus covered stents showed good midterm outcomes as bridging covered stents in FΒ-EVAR. Branches showed higher instability rates compared with fenestrations. Branches showed similar patency rates to fenestrations.

Endovascular Repair of Spontaneous Rupture of Stent Graft Branch in Thoracoabdominal Aortic Aneurysm-Management, Case Study, and Review.

Stent-graft implantation is a widely recognized method for endovascular treatment of aortic aneurysms. In cases where the aneurysm involves the thoracic and abdominal aorta, repair including fenestrated and branched stent grafts provides a viable alternative. This approach, initially reserved for patients unsuitable for open surgery, has become preferred for anatomically appropriate thoracoabdominal aortic aneurysms.

We present the case of a 73-year-old male, recipient of a liver transplant a year ago, with migration of a "Be-Graft" stent used in a pre-transplant transjugular intrahepatic portosystemic shunt towards the pulmonary artery. The stent was incidentally discovered via imaging tests during hospitalization due to acute cholangitis.

Article Synopsis
- Balloon dilation followed by covered balloon-expandable stent (CBS) implantation is shown to be a highly effective treatment for improving blood flow in patients with coarctation of the aorta (CoA), achieving a 100% procedural success rate in a recent meta-analysis.
- The analysis included 12 studies with 411 patients and found significant improvements in pressure gradients and systolic blood pressure after the procedure, along with low overall complication rates.
- Subgroup results indicated that certain stent types, like BeGraft, were associated with higher complications related to access sites, but overall, CBS implantation is deemed safe and effective for CoA treatment.

Article Synopsis
- - Coarctation of the aorta (CoA) is a congenital heart defect found in 3-4 in every 10,000 births, often undiagnosed until adulthood, posing significant risks during pregnancy, including maternal and fetal complications.
- - A case involved a 21-year-old pregnant woman with undiagnosed severe CoA, presenting with high blood pressure and a significant heart murmur, along with weak lower extremity pulses, indicating serious cardiovascular issues.
- - After medical management, her condition required an endovascular procedure to place a stent at 23 weeks' gestation, which successfully improved blood flow and placental health, highlighting the need for careful monitoring and intervention in similar cases.
