Objective To determine the clinical effect of sequence and cross bypass or combined with endovascular procedure for mutilevelarterial occlusive disease of lower extremity so as to investigate the credibletreatment for mutilevel arterial occlusive disease of lower extremity. Methods Between April 2004 and July 2005， 11 patients （14 limbs）underwent sequence and cross bypass, thromboendarterectomy or combined with endovascular procedure. Among of them, 10 cases were male and 1 case was female, aging 62-79 years(mean 70.5 years), and including 8 cases of intermittent claudications (Fontaine stage Ⅱ), 3 cases of rest pain (Fontaine stage Ⅲ) and 1 case of toe ulcerwith gangrene (Fontaine stage Ⅳ). Colour Doppler ultrasonography showed that 14 lower limbswere diagnosed as having multilevel arterial occlusive disease and the preoperation and ankle brachial index(ABI) was 0.36±0.11 . Lower limb digital subtraction angiography(DSA) showed 3 cases of bilateral iliac artery stenosis，extrailiac artery occlusion and bilateral superficial femoral artery occlusions，1 case of right common iliac artery stenosis, extrailiac artery occlusion and bilateral superficial femoral artery occlusions and 8 cases of unilateral extrailiac artery stenosis and superficial femoral artery occlusions. Postoperation tests of DSA,colour Doppler ultrasonography and ABI were done to observe cumulative patency rate after operation. Results The follow-up period was from 3 to 26 months(mean 14.5 months ). All patients survived. The symptoms of intermittent claudication and rest pain disappeard in all patients. ABI was improved by0.89±0.13 after procedure（Ｐlt;0.01）. The overall salvage rate of limb was 100%. DSA was performed from 3 to 280 days after operation, the overall primary graft patency rate was 92.86%（13/14）.Conclusion Sequence and cross bypass， thromboendarterectomy or combined with endovascular procedure in treatment of mutilevel occlusive disease of lower extremity was effective, less invasive and safe.
ObjectiveTo put forward the concept of acute peroneal artery ischemia syndrome, and to study its typical clinical manifestations and imaging features so as to provide the basis of the evidence-based medicine for the diagnosis and treatment of acute peroneal artery ischemia. MethodsBetween October 2009 and December 2012, 3 cases (2 males and 1 female, aged 57, 68, and 71 years) of acute peroneal artery ischemia syndrome were treated. All the patients displayed typical three symptoms of "peroneal artery blood supply zone pale/red + severe pain of the gastrocnemius muscle + acute drop foot". Medical examination revealed that they all had localized tenderness in the lateral and inferior part of the gastrocnemius muscle, with decreasing of skin temperature. The pulse of dorsalis pedis artery and the posterior tibial artery on affected limbs could be felt. Blood coagulation function and biochemical assay showed that D-dimer, fibrinogen degradation products, creatine kinase, or myoglobin markedly elevated. Magnetic resonance angiography revealed proximal peroneal artery stenosis. All patients were treated with intravenous thrombolysis, anticoagulation, vasodilation, and improving circulation therapy. ResultsThe symptoms of lower limb swelling, pain, and fatigue were improved obviously in all patients after treatment. Blood coagulation function and biochemical assay showed D-dimer, fibrinogen degradation products, creatine kinase, or myoglobin were gradually reduced. The patients were discharged at 9-13 days after treatments, without recurrence during the follow-up of 1year. ConclusionAcute peroneal artery ischemia syndrome is a special type of acute lower limb ischemia, with the three symptoms of "peroneal artery blood supply zone pale/red+ severe pain of the gastrocnemius muscle + acute drop foot" as the main characteristics and should be treated by early active anticoagulant and recanalization therapy.
