New vascular ring connectors in surgery for intramural haematoma of the abdominal aorta progressing to rupture

摘要

Aortic intramural haematoma is similar to classic aortic dissection, which causes a life-threatening medical condition, and immediate diagnosis and treatment are crucial. The optimal therapy for intramural haematoma of the abdominal aorta remains controversial. Conservative medical management is usually the first choice of treatment for uncomplicated cases. Surgical intervention is usually required for complicated intramural haematomas of the abdominal aorta, including conventional open repair and endovascular treatment with stent-grafts. A new vascular ring connector that achieves a quick, blood-sealed and sutureless anastomosis has been designed for aortic dissection. We herein report a case of intramural haematoma of the abdominal aorta, progressing to rupture on day 14 after onset, which had successful aortic repair with the new vascular ring connector. The new vascular ring connector could be an alternative method for the treatment of complicated intramural haematomas of the abdominal aorta.
