What are the symptoms of arterial pseudoaneurysm and how to treat aneurysm

What are the symptoms of an arterial pseudoaneurysm? How are aneurysms treated?

1. Most pseudoaneurysms have progressive pain and an expansive and pulsating mass. A systolic blowing-like vascular murmur can be heard at the site of the mass. When combined with an arteriovenous fistula, it is a continuous rumbling murmur. The murmur weakens or disappears immediately when the proximal blood flow is compressed and blocked.

2. Depending on the location of the pseudoaneurysm, there are special clinical manifestations: pseudoaneurysms located in the deep femoral artery may cause obvious swelling and pulsating pain in the upper thigh; retroperitoneal pseudoaneurysms caused by rupture of abdominal aortic aneurysm are mainly manifested by sudden low back pain; pseudoaneurysms located in the skull or wrist are more prone to surrounding compression symptoms due to spatial limitations, manifested as focal symptoms and localizing signs; pseudoaneurysms at the origin of the vertebral artery may cause dysphagia, tracheal displacement, stridor, etc. due to their compression of surrounding tissues.

3. There have also been reports of thoracic aorta rupturing into the esophagus and abdominal aorta rupturing into the intestines, causing corresponding symptoms. Infectious pseudoaneurysms are usually accompanied by systemic and local inflammatory reactions, including fever, fatigue, redness, swelling, heat, and tenderness. The pulsation of the mass may be difficult to palpate due to the swelling of the surrounding soft tissues.

How are aneurysms treated?

1. Tangential resection and arterial repair of saccular aneurysm: After tangential resection of the saccular aneurysm, the side wall of the artery is repaired to restore blood flow.

2. Intra-aneurysm suture repair: It is suitable for pseudoaneurysms that are closely adhered to surrounding tissues or organs and have unclear boundaries. The defective hole in the arterial wall is repaired by suture through the aneurysm cavity. If the repair causes obvious stenosis of the arterial lumen and affects the smooth blood flow, a patch transplant can be added for repair.

3. Aneurysm wrapping: It is suitable for patients whose aneurysms cannot be removed or cannot tolerate aneurysm removal. Fabrics such as polyester and silk are used to wrap the aneurysm to limit the development of the aneurysm.
