Abstract
Purpose:
Traumatic popliteal pseudoaneurysms may occur in accidents or as an iatrogenic complication of a total knee arthroplasty. Complications often arise in open repair because of distorted anatomy. Up to 22% of the patients may suffer above-knee amputation. Endovascular treatment has proven to be an effective solution. However, the long-term performance of stents at the hinge point of the popliteal artery is questionable. We present a hybrid technique that was used successfully in 2 cases.
Technique:
Our approach takes advantage of both open and endovascular techniques. At first, we apply a stent graft at the side of the injury to cover the arterial trauma and stop blood leakage to the aneurysm sac. This allows for a safer dissection and open repair. We clamp the artery proximally and distally, open the sac, extract the stent graft, and extend to a longitudinal arteriotomy. We then reconstruct the entire area with a standard in lay end-to-end anastomosis using a vein graft. This hybrid technique may reduce the risk of uncontrollable bleeding and allow for a safer nerve decompression.
Conclusions:
Repair of such injuries is technically demanding. A hybrid approach may reduce the risk of complications and offer excellent long-term outcomes.
Clinical Impact
The hybrid approach to the treatment of traumatic popliteal pseudoaneurysms combines the advantages of both open and endovascular approaches. It may be possible to make an acute operation just as safe as an elective operation by implementing the proposed strategy. The procedure can be performed by surgeons of all levels, and patients may benefit from a safer surgical dissection with fewer complications and blood loss. This smart combination of standard techniques may prove invaluable in a hostile surgical environment where limb loss is likely.
