Pseudoaneurysm of the Perforating Branch of the Deep Femoral Artery Following Anterior Cruciate Ligament Reconstruction

Okayama University Scientific Achievement Repository

V ascular injury associated with anterior cruciate ligament (ACL) reconstruction is a very rare complication of arthroscopic surgery.  A few cases of pseudoaneurysm following ACL reconstruction have been reported [1-3].  To the best of our knowledge,  there are no previous reports of pseudoaneurysm associated with the outside-in technique for femoral tunnel creation.  Herein,  we present the ﬁrst pub-lished report of pseudoaneurysm of the perforating branch of the deep femoral artery (DFA) following ACL reconstruction using the outside-in technique.Case Report　 The patient and his parents gave informed consent for publication of this case in a medical journal.  A 19-year-old man initially presented with ACL rupture of his right knee,  resulting from twisting his knee during badminton.  Two months after the injury,  the patient underwent anatomic double-bundle ACL recon-struction using semitendinosus tendon autograft in our hospital.  An air tourniquet was used during the sur-gery at 280 mmHg for 50 min.  An outside-in femoral drill aimer (Smith & Nephew,  Andover,  MA，USA) was introduced into the anteromedial portal with the knee ﬁxed at 90℉ of ﬂexion.  A 7-mm longitudinal skin incision for anteromedial (AM) tunnel creation was made at the point where the drill sleeve contacted the femoral lateral skin through the iliotibial band,  allow-ing for insertion of the guide wire sleeve into the bone.  Then,  a 2.4-mm guide wire was inserted to conﬁrm Acta Med.

A guided pin was then advanced until it reached the tip of the femoral aimer.  In the same manner,  a guided pin for the posterolateral (PL) tunnel creation was inserted.  Then,  the guided pins were over-drilled using 5.5 and 6.0-mm-diameter cannulated reamers according to the diameter of the graft consisting of the AM and PL bundles [4].  Tibial tunnels were created using a tibial guide set at 45℉.  After creating two femoral and 2 tibial tunnels,  each graft was passed through each tunnel.  Femoral ﬁxation was achieved using an EndoButton system (Smith & Nephew).  Graft ﬁxations were performed with 30 N for the AM bundle and 20 N for the PL bundle using double-spike plates (Meira,  Aichi,  Japan).  A concomitant medial meniscal tear was repaired with the FasT-Fix 360 system (Smith＆Nephew) at the time of operation.  All skin incisions were closed with 3-0 nylon sutures.  The tourniquet was released after gauze dressing,  with no active bleeding noted.　 Seven days after the surgery,  knee motion and partial weight-bearing were started.  He complained of lateral knee pain during knee range of motion and pre-sented swelling with local heat on the distal lateral thigh just around the small incisions.  To exclude the possibility of postoperative infection,  magnetic reso-nance imaging (MRI) was performed 9 days postopera-tively.  The MRI showed the presence of hemato-ma-like mass with a diameter of 20 mm on the distal lateral thigh (Fig. 1).  The hematoma-like mass was punctured and a large quantity of pulsatile fresh blood was gushing out.  Color Doppler showed turbulent ﬂow within the mass and the ﬁnding was consistent with the diagnosis of pseudoaneurysm (Fig. 2).  Computed tomography angiogram (CTA) conﬁrmed a 20-mm pseudoaneurysm arising from the perforating branch of the DFA (Fig. 3A,B).  Twelve days after ACL reconstruction,  open surgery was performed by a vas-cular surgeon.  A vertical incision was made parallel to the iliotibial tract and the pseudoaneurysm was exposed between the iliotibial tract and femur (Fig. 4A,B).  Both proximal and distal ends of the pseudo-aneurysm were ligated and it was resected.  The histo-pathological evaluation showed a pseudoaneurysm.　 Swelling and pain around the distal lateral thigh immediately disappeared after resection of the pseudo-aneurysm.  Then,  the patient re-started rehabilitation,  achieving full knee range of motion 3 months after ACL reconstruction.  Nine months after the operation,  the patient returned to sports activities without any complaints about his knee.Discussion　 Knee arthroscopy has been developed as a safe and minimally invasive surgery.  The incidence of iatro-genic vascular injury following knee arthroscopic sur-gery ranges from 0.56 to 0.80  [5,6].  There have been several reports of pseudoaneurysms after ACL reconstruction [1,7,11].  Most of them arose from the popliteal artery and inferior genicular artery.  To the best of our knowledge,  this is the ﬁrst case of a pseudoaneurysm arising from the perforating branch of the deep femoral artery (DFA) following outside-in ACL reconstruction.  The outside-in technique is one of the most commonly used methods for the femoral tunnel creation in ACL reconstruction.  It creates a femoral tunnel of adequate length and obliquity through the ACL femoral footprint with minimal inci-dence of posterior wall blow out [12].  However,  the disadvantage of this technique is the additional incision on the distal lateral thigh.  The DFA lies deep in the thigh and it gives oﬀ 3 of 4 perforating branches.  The perforating branch of the DFA can run near the distal 516 Fujii et al. Acta Med.

In the pres-ent case,  CTA showed that the pseudoaneurysm had developed near the stab incision for AM femoral tun-nel creation.  Because it was located between the skin incision and the EndoButton,  we hypothesized that a sharp-pointed knife for making stab incision or guided pin insertion might injure the artery.  To avoid this complication,  the surgeon should make a minimum incision for femoral tunnel creation and dissect the iliotibial band carefully.  If the surgeon uses an air tourniquet,  its temporary release during femoral tun-nel creation could possibly detect any vascular injury.　 Vascular injury following arthroscopic surgery may often be overlooked due to delayed presentation because of indeterminate symptoms such as knee pain and swelling.  In this case report,  the patient com-plained of lateral knee pain and presented with swell-ing with local heat on the distal lateral thigh seven days postoperatively.  First,  we suspected postopera-tive infection of the knee.  MRI,  CTA,  and color Doppler helped us recognize the occurrence of pseu-doaneurysm.  Pseudoaneurysms typically present late with clinical signs such as pain and swelling,  and the development of a pulsatile mass may suggest the diag-nosis [13].  Careful examination around the knee is essential for early diagnosis of pseudoaneurysm after knee arthroscopic surgery.  　 Current therapeutic approaches to pseudoaneu-December 2016 Pseudoaneurysm Following Anterior Cruciate Ligament Reconstruction 517Fig.  2　 Color Doppler showing turbulent ﬂow within the saccular structure around the lateral femoral condyle (LFC).Fig.  3　 Contrast-enhanced computed tomography angiogram of the right lower limb showing a pseudoaneurysm of the perforating branch of the deep femoral artery.

A recent review article reported that resection was the treatment most frequently described in the literature,  accounting for 75  of the pseudoaneurysms resulting from knee arthroscopy [17].  In the present case,  surgical resection was successfully performed by a vascular surgeon.  Seven months after operation,  the patient regained full range of motion and muscle strength.Conclusion　 In conclusion,  even if the arthroscopic ACL recon-struction is minimally invasive and very low incidence of vascular injury,  surgeons should understand the detailed anatomy of artery around the knee.  The pres-ent case report suggests that it is especially important to be aware of the presence of the perforating branch of the DFA,  which can run very near the additional incisions in the outside-in technique.  Although it is very diﬃcult to prevent vascular injury,  careful fol-low-up after surgery may help surgeons recognize that complication as early as possible.Acknowledgments. 　We thank Mr. Ei-ichi Ishikawa and Ms. Yoko Yamakawa for their technical cooperation.References 1.
