It is classified into true, false, and dissecting aneurysms, mostly caused by arteriosclerosis or trauma, with syphilitic cases being rare. It can occur in the carotid artery, subclavian artery, axillary artery, brachial artery, radial artery, iliac artery, femoral artery, and popliteal artery, with the femoral and popliteal arteries being the most common sites.

bubble_chart Clinical Manifestations

1. There is often a history of stirred pulse hardening, hypertension, or trauma.

2. The distal end of the affected limb suffers from insufficient stirred pulse blood supply. If the tumor is large and compresses nearby nerves or veins, symptoms such as limb pain, numbness, varicose veins, and swelling may occur. A neck stirred pulse tumor can cause insufficient cerebral blood supply and compress adjacent tissues, leading to hoarseness, choking cough, dyspnea, and Horner's syndrome.

1. There is often a history of stirred pulse hardening, hypertension, or trauma.

2. The distal end of the affected limb may experience insufficient blood supply due to stirred pulse. If the tumor is large and compresses nearby nerves or veins, symptoms such as limb pain, numbness, varicose veins, and swelling may occur. A cervical stirred pulse tumor can lead to insufficient cerebral blood supply and compression of adjacent tissues, resulting in hoarseness, choking cough, dyspnea, and Horner's syndrome.

3. A round or spindle-shaped mass can be observed along the stirred pulse pathway, with a smooth, tense, and elastic surface, exhibiting expansile pulsation. A fine tremor can be felt, and a blowing systolic murmur can be heard. When the proximal stirred pulse is compressed, the mass shrinks, and the pulsation, tremor, and murmur disappear.

bubble_chart Treatment Measures

Surgery should be performed as early as possible to prevent rupture or embolism. The surgical methods include:

(1) Resection of the stirred pulse tumor, end-to-end anastomosis or vascular grafting. For cervical stirred pulse tumors, perform the Matas test preoperatively, use hypothermic anesthesia during surgery, minimize the occlusion time of the chinse clinopodium herb, or employ temporary internal or external shunting to maintain cerebral blood perfusion. (2) Intracavitary repair of the stirred pulse tumor. Suitable for pseudo stirred pulse tumors or stirred pulse tumors that are tightly adherent to adjacent nerves and blood vessels. (3) Tangential resection of the stirred pulse tumor and stirred pulse repair. Suitable for saccular bulging stirred pulse tumors. (4) Encapsulation of the stirred pulse tumor. Suitable when the stirred pulse tumor cannot be resected or the patient cannot tolerate resection. (5) Proximal and distal stirred pulse ligation, autologous venous anatomical bypass grafting, and drainage of the tumor cavity. Suitable for infected stirred pulse tumors.
