Surgical treatment of popliteal artery entrapment syndrome: a ten-year experience.
Popliteal artery entrapment syndrome is increasingly described in the world literature as a cause of lower limb arterial impairment. It is caused by the anomalous interrelationship between the popliteal artery and its surrounding muscular and/or tendineous structures. The first case surgically treated was reported in 1959 and since then more than 300 cases have been reported including our personal experience (31 cases in 23 patients). We have treated surgically 19 males and four females with symptoms which were moderate (cramping after intensive physical training, paraesthesia, etc.) in 14 limbs, intermittent claudication in 16 and necrosis (first toe) in one. Preoperative arteriography showed arterial occlusion in eight limbs, stenosis in eight and aneurysms in two. In 11 limbs stenosis or occlusion was only shown after active plantar hyperextension and in two arteriography was not done because surgical indications were established on the basis of a venogram positive for popliteal vein entrapment syndrome. Ten different anatomical variants were seen and the medial head of gastrocnemius muscle was involved in 74.2%. Surgical treatment consisted of division of the aberrant musculotendinous tissue in 18 cases (in two of these balloon angioplasty was also used). In 12 cases a vascular reconstruction was also required, while one case was explored without a specific procedure being warranted. Optimal results were obtained when the syndrome was treated at an early stage by simple division of musculotendinous tissue (94.4% long-term patency rate, mean follow-up 46.0 months, min 2, max 120 months). When arterial grafting was required the long-term patency rate was only 58.3% (mean follow-up 43.5 months, min 1, max 100 months).(ABSTRACT TRUNCATED AT 250 WORDS)
