Clinical Value of Minimally Invasive Bridging for the Lateral Malleolar Fractures in the Open Comminuted Ankle Fractures with Dislocation / 中国医学科学院学报

To evaluate the effectiveness of minimally invasive bridging for the lateral malleolar fractures in the open comminuted ankle fractures with dislocation. Methods The clinical data of 24 patients [19 males and 5 females aged 40 to 65 years,mean(47.5±8.6)years] with open comminuted ankle fractures with dislocation who were treated in the Second Hospital of Tangshan from September 2015 to June 2017 were retrospectively analyzed.All patients were treated with minimally invasive bridging for the lateral malleolar fractures.The ankle function after treatment was assessed with the Olerud Molander Ankle(OMA)score. Results All the 24 patients were followed up from 12-26 months [mean:(14.5±2.6)months].Good fracture union was achieved in all patients after 2 - 5 months(mean:3 months).No deep infection,skin necrosis,or bone nonunion occurred after 12 months of follow-up.Only one patient suffered from partial skin necrosis at lateral malleolus,which was cured after changing wound dressings.The OMA score was 93.5(range:85-100)after 12 months(excellent in 19 cases and good in 5 cases). Conclusions Minimally invasive bridging for the lateral malleolar fractures is effective in treating the open comminuted ankle fractures with dislocation.It can obtain good reduction and fixation,reduce complications,and achieve high union rate.

Embolization of craniofacial arteriovenous malformations after the ligation of external carotid artery / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To introduce the method of retrograde embolization through the superficial temporal artery (STA) after the ligation of external carotid artery (ECA) for the treatment of craniofacial arterio-venous malformations (AVM).</p><p><b>METHODS</b>Seven cases of craniofacial AVM were included in the study. After the ligation of ECA, the STA was surgically accessed and a 4F (1F = 0.333 mm) sheath introduced into the artery, and N-butyl-2-cyanoacrylate (NBCA) was selected as the permanent embolization material.</p><p><b>RESULTS</b>The angiogram was successfully carried out in these cases, which showed that some collateral branches from the ophthalmic artery of left internal carotid artery, vertebral artery and thyrocervical trunk provided the blood supply to the AVM nidus. The retrograde embolization with NBCA was completed.</p><p><b>CONCLUSIONS</b>The vascular architecture of craniofacial AVM after the ligated ECA was better demonstrated in angiogram of vertebral artery. The retrograde embolization through STA was an effective method for the treatment of craniofacial AVM.</p>
