Aortic dissections are life-threatening conditions where a tear in the aorta's inner wall causes blood to flow between the layers of the vessel, leading to potential rupture or organ damage. Endovascular stent grafting is a minimally invasive technique used to repair the damaged section of the aorta and restore normal blood flow. However, this procedure is among the most expensive and complex in interventional radiology, and understanding the costs and challenges involved can help patients make informed decisions.
The high cost of endovascular stent grafting is driven by several factors. The stent graft itself is a specialised device, custom-made to fit the patient's unique anatomy and the exact size and shape of the dissected aorta. These grafts are constructed from advanced materials that combine flexibility with durability, allowing them to withstand high blood pressure within the aorta. Additionally, the procedure requires state-of-the-art imaging technology to precisely guide the stent into place, ensuring that the graft covers the tear without blocking blood flow to vital organs.
The complexity of the procedure also contributes to its cost. Treating an aortic dissection involves navigating the stent graft through the blood vessels from the groin to the aorta under real-time imaging. The delicate nature of the aorta and the potential for complications, such as endoleaks or malpositioning of the stent, require a high level of expertise and meticulous planning. As an experienced Interventional Radiologist, I ensure that every aspect of the procedure is performed with the utmost precision to minimise risks and achieve the best outcomes.
When deciding whether endovascular stent grafting is appropriate, I consider the location and extent of the dissection, the patient’s overall health, and any underlying conditions. In cases where the dissection involves vital branches of the aorta, a more complex stent graft with fenestrations or branched designs may be necessary, adding to the intricacy and cost of the procedure. I also assess whether surgical intervention might be a more suitable option for some patients, depending on their risk factors and anatomy.
My approach involves thoroughly explaining the treatment options, risks, and expected outcomes to my patients, helping them make informed choices. With years of experience in managing aortic dissections, I am dedicated to providing personalised care and using the latest endovascular techniques to ensure optimal results for each patient.
