Successful Urgent Endovascular Treatment of Acute Thoracoabdominal Aortic Type B Dissection in a Young Patient: Case Presentation and Findings at Late Follow-up

Aortic dissection is a critical condition leading to significant mortality and morbidity. Urgent endovascular treatment is an attractive treatment option in selected Patients. A 46-year-old woman was admitted to the emergency room for sudden onset of severe abdominal pain radiating to the lower back with paresthesia of the right lower limb. CT scan revealed an acute thoracic aortic dissection at the level of the left subclavian artery descending into the abdominal aorta and both iliac arteries, with a compressed and thrombosed true lumen causing vascular infarcts in the right kidney. A stent-graft was deployed as soon as the patient’s vital signs were stabilized. CT and clinical follow-up revealed no signs of complication and a complete resolution of symptoms. In the presented case the endovascular approach resulted in a prompt and durable resolution of symptoms and underlying causes, which also allowed substantial renal parenchyma salvage.
