Thoracic Endovascular Aortic Repair (TEVAR)
Understanding Aortic Aneurysm: Causes, Symptoms, Diagnosis, and Treatments
Thoracic Endovascular Aortic Repair (TEVAR) is a cutting-edge procedure used to treat a variety of thoracic aortic diseases, including thoracic aortic aneurysms, aortic dissections, and traumatic aortic injuries. This minimally invasive technique involves inserting a stent graft through small incisions in the groin or chest and guiding it into the diseased segment of the aorta using X-ray imaging. Dr. Devender Singh, a distinguished vascular surgeon in Hyderabad, specialises in performing TEVAR with precision and expertise, offering patients safe and effective treatment options for complex aortic conditions.
Understanding Thoracic Endovascular Aortic Repair (TEVAR):
TEVAR is a minimally invasive alternative to traditional open surgery for thoracic aortic diseases. During the procedure, a catheter-mounted stent graft is inserted into the femoral artery through a small incision in the groin and advanced to the diseased segment of the aorta under X-ray guidance. Once in position, the stent graft is deployed, providing a new reinforced channel for blood flow and excluding the diseased aortic segment from circulation. This reduces the risk of aortic rupture, relieves symptoms, and promotes aortic remodelling.
Procedure Overview:
Preoperative Evaluation:
- Before undergoing TEVAR, patients undergo a comprehensive evaluation, including medical history review, imaging studies (such as CT or MRI scans), and vascular assessments to determine the extent and severity of the aortic disease.
Anaesthesia and Access:
- TEVAR is typically performed under general anaesthesia to ensure patient comfort and safety throughout the procedure.
- Small incisions are made in the groin or chest area to access the femoral artery and gain entry into the vascular system.
Stent Graft Deployment:
- Using X-ray imaging guidance, a catheter-mounted stent graft is advanced through the femoral artery and positioned within the diseased segment of the thoracic aorta.
- The stent graft is then deployed, expanding to fit snugly against the walls of the aorta and sealing off the diseased area.
Postoperative Care and Recovery:
- After TEVAR, patients are monitored closely in the intensive care unit (ICU) or a specialised recovery area to ensure stability and proper healing.
- Most patients can expect to stay in the hospital for a few days following the procedure, with gradual improvement and return to normal activities over the following weeks.
Benefits of Thoracic Endovascular Aortic Repair (TEVAR):
- Minimally Invasive: TEVAR is a minimally invasive procedure that avoids the need for a large chest incision and prolonged recovery associated with traditional open aortic surgery.
- Reduced Mortality and Morbidity: TEVAR has been shown to significantly reduce mortality and morbidity rates compared to open surgical repair for thoracic aortic diseases.
- Faster Recovery: TEVAR typically results in shorter hospital stays, faster recovery times, and reduced postoperative pain and discomfort compared to open surgery.
- Improved Aortic Remodelling: By reinforcing the weakened aortic wall and promoting thrombosis within the aneurysmal sac, TEVAR can lead to long-term aortic remodelling and reduced risk of future complications.
