From the Guidelines
The Viabahn stent graft is indeed available in a rapid exchange system, which facilitates single-operator handling and quicker catheter exchanges during endovascular procedures. This is crucial in reducing procedure time and potentially decreasing radiation exposure, especially in complex peripheral vascular interventions where multiple device exchanges may be necessary. The Viabahn RX Endoprosthesis features a design that enables the physician to maintain guidewire position while exchanging catheters, which is a significant advantage in procedures involving the superficial femoral artery, as discussed in the guidelines on the diagnosis and treatment of peripheral artery diseases 1. Key characteristics of the Viabahn stent graft include its flexibility, self-expanding nitinol structure, and coverage with expanded polytetrafluoroethylene (ePTFE), making it suitable for treating peripheral arterial disease and other vascular conditions. Some of the benefits of using a rapid exchange system like the one featured in the Viabahn stent graft include:
- Reduced procedure time
- Potential decrease in radiation exposure
- Ease of catheter exchange
- Maintenance of guidewire position during exchanges
- Suitability for complex peripheral vascular interventions.
From the Research
Viabahn Endovascular Stent Graft Characteristics
- The Viabahn stent graft is used for endovascular therapy to treat various vascular conditions, including arteriovenous fistulas and popliteal artery aneurysms 2, 3.
- It is deployed using a unique release line-based deployment mechanism, which allows for minimally invasive endovascular intervention 2.
- The Viabahn stent graft has been used in various studies to treat complex aortic aneurysms, with satisfactory technical and clinical results 3, 4.
- However, the provided studies do not explicitly mention whether the Viabahn stent graft is a rapid exchange system.
Deployment Mechanism and Technical Success
- The deployment mechanism of the Viabahn stent graft allows for technical success in various endovascular procedures, including the treatment of popliteal artery aneurysms and complex aortic aneurysms 3, 4.
- The technical success rate of the Viabahn stent graft has been reported to be high, with rates of 100% in some studies 3, 5.
- The Viabahn stent graft has been used in conjunction with other endovascular techniques, such as cutting balloon angioplasty, to achieve technical success in complex cases 2.
Clinical Applications and Efficacy
- The Viabahn stent graft has been used to treat various vascular conditions, including arterial injury and bleeding at the visceral arteries, with initial and midterm results showing efficacy and safety 5.
- The Viabahn stent graft has also been used in the treatment of supra-aortic vessels, with a novel sutureless telescoping anastomosis technique showing promise 6.
- The clinical success rate of the Viabahn stent graft has been reported to be high, with rates of 100% in some studies 5.
