What is a peripheral aneurysm?

summary

Aneurysms are localized bulging or fusiform dilating lesions caused by arterial wall lesions or injuries. The main symptom is pulsatile mass, which can occur in any part of the arterial system. Peripheral aneurysms refer to the aneurysms occurring in the arterial area outside the aorta, most commonly in the femoral and popliteal arteries. What is a peripheral aneurysm? Let's talk about it

What is a peripheral aneurysm?

The typical manifestation of aneurysms is pulsatile mass with smooth surface, accompanied by tremor and murmur. Compression of the proximal artery can reduce the mass, tension, tremor and murmur. With the gradual expansion of the aneurysm, local swelling pain or jumping pain may appear, and sudden pain or sudden aggravation of pain may be the precursor of acute expansion or rupture of the aneurysm.

Due to its space occupying effect, aneurysms can compress peripheral nerves, veins and organs, resulting in corresponding symptoms. The symptoms vary with the location and compression structure of the aneurysm. Nerve compression can cause sensory and motor disorders; Compression of veins can lead to obstruction of reflux and limb swelling.

The mural thrombus and atherosclerotic plaque falling off in the aneurysm cavity can lead to distal arterial embolism and acute ischemia. The symptoms vary with the size of the embolus and the location of the embolus. There may be distal limb pain, pallor, chills, numbness, sensory, motor disorders and acromegaly. Popliteal aneurysms are the most dangerous of lower extremity aneurysms.

matters needing attention

For minimally invasive treatment, covered stent was implanted into the aneurysm and anchored to the normal arterial wall at both ends, so as to isolate the aneurysm and reconstruct the blood supply. It has the advantages of small trauma, definite curative effect and quick recovery, but the indications should be strictly controlled.
