According to Sina Media, Dr. Javad Salimi, a professor of vascular surgery at Tehran University of Medical Sciences, described the patient's case in a conversation with the public relations office of Sina Hospital. The patient, a 47-year-old woman, had undergone placement of a stent graft in the thoracic aorta at another medical center two years ago due to extensive aortic dissection (Aortic Dissection). Unfortunately, due to the progression of the disease and its extension to the abdominal aorta, she returned to Sina Hospital after two years. Before coming to Sina Hospital, she had visited multiple treatment centers across the country, but due to the extent and progression of her disease, she was refused admission.
Further examinations revealed an increase in the size of the thoracic aneurysm to 7 cm, while the diameter of the abdominal aortic aneurysm increased to 8 cm, which had led to involvement of the renal and visceral arteries as well.
He added that performing conventional surgery in such patients was associated with a very high risk of mortality; therefore, advanced endovascular techniques were utilized for the treatment of the patient.
The selected method for the patient was the T-Branch EVAR utilizing a specialized stent graft, which not only repaired the thoracic and abdominal aneurysm but also preserved blood flow in the renal and visceral arteries.
Fortunately, the endovascular procedure was successfully completed in two stages with a one-month interval (to prevent complications related to spinal cord blood supply disruption), and the patient was discharged in good general condition.
In a CT angiography performed one month after the surgery, the thoracic and abdominal aortic aneurysm had completely resolved.
The professor at Tehran University of Medical Sciences described aortic dissection and stated that it usually occurs due to a disorder in the arterial wall tissue or high blood pressure, leading to increased size and risk of aortic rupture.
Today, the use of endovascular methods is considered the preferred treatment for these patients. In most cases, when the thoracic aorta is minimally involved, conventional endovascular methods can be utilized for treatment. However, in cases where there is extension to the abdominal aorta and involvement of the renal arteries and arteries supplying blood to the liver and other organs, the use of advanced endovascular methods is essential.
Dr. Javad Salimi, a specialized vascular surgeon, Dr. Mohammad Reza Neshabouri, an anesthesiologist, Dr. Alireza Sharifnia, also an anesthesiologist, along with vascular surgery fellows, anesthetic assistants, and the nursing staff of the angiography and vascular surgery department at Sina Hospital were members of this advanced team.
