Objective To explore the specific causes of common peroneal nerve injury, characteristics of such injured nerve's electrophysiological performance and its diagnostic value.Methods The clinical and neurophys-iological examination data of 7 patients with common peroneal nerve injury were retrospectively analyzed.Results The patients of common peroneal nerve injury cause for long time squatting down.Compared with the healthy side, potential amplitude of the deep peroneal nerve or the superficial proneal nerve of the injured side changes more obviously.On the average the amplitude fell by about 50% with the largest drop by 88%.EMC indicated that the muscle controlled by injured nerve has spontaneous potential,reduced recruitment and so on.Conclusion Long time squatting down was relatively rare cause for common peroneal nerve injury.Neural physiological detection could provide more specific positioning diagnosis and differential diagnosis for common peroneal nerve injury,had better clinical application value.

Objective Repair of aortic arch aneurysm is technically demanding and usually requiring complex circulatory management. Operative morbidity and mortality may be prohibitive with traditional surgical intervention. We described our experience with 5 hybrid endovascular procedure for aorta repair with different kinds of bypass followed by concomitant placement of stent graft in the aorta. Methods We retrospectively reviewed the clinical data of 5 consecutive patients presenting with aortic aneurysm or dissection from 2007 to 2008 treated by the hybrid aorta repair. Complete surgical rerouting of the supra-aortic vessels was followed by endovascular repair of aortic arch aneurysm with a Zenith TX2 stent graft. Hybrid left carotid-subclavian bypass with Zenith stent graft deployment covering the ostium of the LSA was performed in a Debakey type Ⅲ aortic dissection case. Procedures were successfully completed with exclusion of the aortic aneurysm. All stent grafts were deployed retrograde from the femoral artery in these patients. Results Technical success with complete aneurysmal exclusion was achieved in all patients (100%). At a follow-up period of 2-10 months, there was no incidence of endoleak. Documented perioperative neurelogic events did not occurred in all patients. Postoperatively one patient suffered from ARDS and cardiac failure and recovered. One patient died of myocardial infarction. Conclusions Hybrid arch repair provides an alternative to patients otherwise considered prohibitively high risk for traditional open arch and thoracoabdominal aorta repair.
