Popliteal artery injury complicating arthroscopic menisectomy.
Inadvertent popliteal artery injury during arthroscopic menisectomy is an unusual occurrence. Prompt diagnosis and treatment are essential to achieve a good outcome, as illustrated in two of the five patients described herein. Pitfalls in diagnosis led to late recognition and therapy in three patients, with subsequent serious complications; namely, arteriovenous fistula, false aneurysm, and amputation. On the basis of this limited but poignant experience, we propose an outline of steps in management to help others avoid similar problems. If popliteal injury is suspected, we advise exploration immediately to avoid a potential limb-loss crisis. Heparin should be given as soon as diagnosis is made. A posterior incision in the knee crease, rather than the conventional medial approach, gives expedient exposure for precise repair. We also advise passing a no. 3 thrombectomy catheter distally to rule out or retrieve any clot that may have embolized. A completion angiogram is also helpful. Compartment pressure may be measured, but if any doubt exists, a three-compartment fasciotomy should be performed.
