![]() Moreover, the patient hesitated the surgical treatment at that time. Although CK level was highly elevated, we did not consider emergent surgical treatment as other parameters were normal or only slightly elevated. However, the severity was not considered urgent as the Doppler detected pedal artery flow and the duplex scan detected CFA flow, both indicating that the blood flow to the right lower limb was maintained by collateral circulation. The pathological state was similar to acute limb ischemia, and Rutherford classification was category I. With respect to inflammatory reaction, the white blood cell count and C-reactive protein level were slightly increased at 9630/μL and 0.87 mg/mL, respectively. ![]() Glutamic pyruvic transaminase, lactate dehydrogenase (LDH), and potassium were normal with levels of 28 IU/L, 197 IU/L, and 4.5 mEq/L, respectively. Laboratory examination showed an elevated creatine kinase (CK) level of 1302 IU/L and slightly elevated glutamic oxaloacetic transaminase level of 43 IU/L. ![]() ![]() The right ankle–brachial index (ABI) was 0.50. A duplex scan showed no flow in the right EIA and small flow in the distal CFA. There was a contrast effect in the distal CFA just before the branching of the superficial and deep femoral arteries and the collateral circulation. Contrast computed tomography (CT) for the evaluation of bone fracture or active bleeding revealed vascular occlusion extending from the right EIA to the CFA (Fig. There was no palpable pulse in the right pedal artery, but flow was recognized by pulse Doppler ultrasound. Consistent with subcutaneous hematoma, the colors of the right and left leg were similar in the resting state however, the right leg became pale after walking and he noticed mild claudication. Although the numbness of the right lower limb that began immediately after the impact gradually improved, the patient was admitted to our hospital with right inguinal pain and swelling. The right handlebar of his bicycle hit his groin. While riding a bicycle, an 18-year-old man (height, 165 cm weight, 60.3 kg) collided with another bicycle coming from the left side. This injury often needs surgical treatment therefore, prompt diagnosis is the key to successful treatment. The presence of vascular injury should be considered in patients with groin or lower abdomen injuries following an impact with handlebars or similar hard objects. Motor-scooter handlebar syndrome is a rare complication of traumatic injury. The postoperative course was good, and the right ABI improved to 1.05. We performed thrombectomy and femoral artery repair with a saphenous vein patch. Contrast computed tomography revealed an occlusion extending from the right external iliac artery to the common femoral artery. Case presentationĪn 18-year-old man visited our hospital complaining of pain and swelling in his right groin and numbness in his right leg after a bicycle collision accident. Traumatic femoral artery occlusion caused by blunt impact to the groin is rare this condition is called the “motor-scooter handlebar syndrome.” We herein report a case of traumatic femoral artery occlusion and performed a literature review on its diagnosis and treatment.
