Aneurysms of the profunda femoris artery are very rare. The frequency of these aneurysms is 0.5-1% of all peripheral atherosclerotic aneurysms. This condition can be symptom free for an extended period of time. In one third of the patients, palpable, pulsating swelling appears in the groin. Complications such as rupture, peripherial embolism, deep vein thrombosis, depending on the condition of the arteries ischaemia in the leg can develop. Treatment of this condition according to the literature is resection of the aneurysm with reconstruction of the artery. Our practice is the same. If diagnosis is achieved surgery is necessary to avoid further complications. The literature review from 1960 presents 51 patients with the disease, we added 3 of our own cases to this number.
