Objective To investigate effects of pedicle processing methods on the survival and appearance of the pedicle flaps. Methods The study involved 17 patients with soft tissue defects of extremities treated with the “exclamation mark” shaped pedicle flaps from October 2009 to January 2011.The traditional pedicled rotation flaps was designed to be a tennis racket-like shape,then the rotational pedicle was designed to small round tension reduction flap and pedicled rotation flaps,which contributed to formation of the “exclamation mark” shaped pedicle flaps.The soft tissue defects was located at the upper extremity in three patients and at lower extremity in 14,with defect areas of 4.0 cm× 7.2 cm-5.8 cm × 14.0 cm.There used two superficial radial nerve vasotrophic flaps,one ulnar artery supra-carpal cutaneous flap,eight sural neurocutaneous vasotrophic flaps and six saphenous nerve vasotrophic flaps.Results All flaps survived at Ⅰ stage except that one flap had partial distal necrosis postoperatively,which was cured after dress change.The follow-up ranged from six months to one year,which showed unobvious swelling of the survived flaps and good appearance of the rotation point of the pedicle. Conclusion The “ex(c)lamation mark” shaped pedicle flaps can reduce entrapment of the distal pedicle,promote venous drainage,improve survival and modify the appearance of the flaps.

Objective To explore the effects of reconstruction and shaping of thumb or finger defects by free second-toe transfer and one stage appearance remodeling.Methods From October,2007 to August,2013,128 thumb or finger Ⅴ degree defect of 109 cases were reconstruct with free second-toe transfer,and one stage shape remodeling at the same time.Among them,20 fingers by nail bed expand one stage; 23 fingers were nail bed expand added on toe pulp splayed resection on both sides; 29 fingers were added on embedded the philp island flap of great toe to the section of plantar side narrow part in the second digit,19 fingers were added on embedded the abdominal phil chamfered-edge-shape flap to that narrow part in the second digit,and 37 fingers added on toe pulp resection and embedded the philp island flap of great toe to that narrow part.Results All reconstructed thumb or fingers survived and appearance were good.The nail shape of reconstructed thumb or fingers were improved obviously,the shape of narrow part in middle segment was recovered satisfactorily.Seventy-nine cases (72.5％) were followed-up from 3 months to 5 years,and the other 30 cases (27.5％) were lost.The function of the reconstructed thumb or finger and hand feeling was ideal recovered.There were no claudication,no pain and no other sequelaes for donor foot.According to the Standard on Approval of Reconstructed Thumb and Finger Functional Assessment of Chinese Medical Association,43 cases excellent,26 cases good,10 cases approve.The rate of excellent and good was 87％.Conclusion Second-toe transfer and shape remodeling is a good method of thumb or finger reconstructing.The appearance of the thumb reconstruction can be improved obviously.Preoperative carefully design and the combination of the above several kinds of operation,for draw up an personalized surgical program is necessary.

Objective To explore the clinical efficacy and safety of hyper-early embolotherapy in treatment of intracranial ruptured aneurysm.Methods A retrospective analysis was made on 33 patients with intracranial ruptured aneurysm.Preoperative Hunt-Hess grade:grade Ⅰ-Ⅱ in 16 patients,gradeⅢin 5 patients,grade Ⅳ in 9 patients,grade Ⅴ in 3 patients.All patients were confirmed with subarachnoid hemorrhage (SAH) by angiography and then underwent embolization under general anesthesia by detachable coils within 6 h from onset.Results After operation,25 patients (75.8％) recovered well,4 patients (12.1％) were with mild disability with paralysis and aphasia,4 patients (12.1％) were dead (1 patient for intraoperative aneurysm rupture,1 patient for postoperative pneumonia,1 patient for infection of hematoma at puncture site and 1 patient for postoperative gastrointestinal bleeding).Followed up 1-6 months,no rebleeding occurred.Conclusions Hyper-early embolotherapy could avoid rebleeding of the aneurysm,and relieve the vasespasm,without increasing the intra-operative rebleeding rate.Moreover hyper-early embolotherapy could greatly decrease the mortality of poor-grade SAH patients.

OBJECTIVETo evaluate the efficacy and safety of mechanical thrombectomy with the Solitaire AB device in recanalization of patients with acute ischemic stroke of posterior circulation.

METHODSThe clinical data of 17 consecutive patients with acute ischemic stroke of posterior circulation, treated with the Solitaire AB device from August 2011 to August 2015 in Department of Neurosurgery, the Military General Hospital of Beijing People's Liberation Army, were extracted and then retrospectively analyzed. There were 12 male and 5 female patients with a median age of 60 years (ranging from 44 to 75 years). Among them, 8 cases occluded in basilar artery, 4 cases occluded in vertebral artery and 5 cases occluded in vertebral plus basilar artery. Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after treatment, measured by National Institute of Health stroke scale (NIHSS) score, were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after treatment.

RESULTSFifteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath time were above 7.5 hours. The NIHSS score at 7 days was 11±10, which was significantly decreased compared to the admission NIHSS score 17±5 (t=2.949, P=0.009). No symptomatic intracranial hemorrhage case was found after thrombectomy. At 90 days, one patient died(mRS 6), one patient seriously disabled (mRS 5), two patients moderately seriously disabled (mRS 4), four patients resulted in moderate outcome (mRS 3) and the other 9 patients achieved good outcome (mRS 0 to 2). The dead and seriously disabled cases were both due to failure in recanalization. Two moderately seriously disabled cases were probably attributed to their severe admission condition (NIHSS >20) and prolonged time (onset to sheath time >6 hours).

CONCLUSIONMechanical thrombectomy with the Solitaire AB device contributes to a high rate of recanalization with a low probability of complication and improves functional outcome in patients with acute ischemic stroke of posterior circulation.

Objective:To evaluate the clinical efficacy of the bridge pedicled transplantation of medial leg fascial flap combined with medial hemisoleus muscle flap for contralateral leg soft tissue defect.Methods:Between January of 2012 and January of 2018, 12 patients with soft tissue defect of the leg were treated with bridge pedicled transplantation of contralateral medial leg fascial flap combined with medial hemisoleus muscle flap by posterior tibial artery. There were 9 males and 3 female, aged from 19 to 53 years (mean, 35 years). The size of the soft-tissue defects ranged from 12 cm×8 cm to 18 cm×9 cm. The immediate coverage of the fascial and muscle flaps and vessel pedicle were repaired by a meshed split-thickness skin graft. The donor site was closed directly. After the transplantation of the one pedicle and two flaps survived, vascular pedicle was cut off.Results:All the fascial and muscle flaps survived completely. No clinical vascular deficiency was found on the fascial and muscle flaps postoperatively. One case developed distal muscle flap small skin graft necrosis, and spontaneous healed after 2 weeks of dressing change. Follow-up period ranged from 2.5 to 4.5 years (mean 3.8 years). A good contour was confirmed both at the recipient and donor sites. Satisfactory clinical results were obtained in this series.Conclusion:This method is suitable for the treatment of soft tissue defects of the leg with only one major blood vessel, which reduces the damage to the donor site.

Objective:To evaluate the efficacy of the repairing anterior tibial adjacent double wounds by transposition with single-pedicle two flaps of the medial head of gastrocnemius.Methods:Between January of 2012 and January of 2018, 10 patients with the anterior tibial adjacent double wounds (7 males and 3 female, aged from 21 to 45 years) were treated by transposition with single-pedicle two flaps of the medial head of gastrocnemius. The size of the soft-tissue defects ranged from 2.0 cm×2.5 cm to 4.5 cm×4.0 cm. The medial head of the gastrocnemius was divided into two flaps with a single pedicle to repair two adjacent wounds of the anterior tibial. The muscle flaps were immediately covered by a meshed split-thickness skin graft, and the wound in donor site was closed directly.Results:All the muscle flaps survived completely. No clinical vascular deficiency was found on the muscle flaps postoperatively. Small wound dehiscence was developed in one patient and spontaneously healed 2 weeks after dressing change. Patients were followed up for 2.0 to 4.5 years. A good contour was confirmed at the recipient and donor sites. Satisfactory clinical results were obtained in this series.Conclusion:This method is suitable for the repair of two adjacent small wounds of the anterior tibial which can reduce the damage to the donor site.

Objective To investigate the effectiveness of evoked potential in monitoring cerebral perfusion during carotid endarterectomy by a retrospective cohort study.Methods A retrospective cohort survey of clinical data of 59 patients,who underwent carotid endarterectomy in our hospital from September 2013 to December 2016,was performed.All patients were monitored by transcranial doppler ultrasonography (TCD) and somatosensory evoked potential (SEP),motor evoked potential (MEP) for changes of cerebral blood flow;the monitoring of TCD was defaulted as "gold standard",recording monitoring results at different time points.By drawing the four table,the sensitivity,specificity,positive predictive value,negative predictive value of SEP and MEP during cerebral hypoperfusion were calculated,and correlation analyses between SEP and TCD,and between MEP and TCD were performed.Through receiver operating characteristic (ROC) curve,SEP monitoring threshold of cerebral hypoperfusion was predicted.Results The sensitivity,specificity,positive predictive value,and negative predictive value of SEP in predicting intra-operative cerebral hypoperfusion were 60.00％,91.84％,60.00％,and 91.84％ when SEP amplitude declined beyond 50％;the sensitivity,specificity,positive predictive value and negative predictive value of SEP in predicting intra-operative cerebral hypoperfusion were 70.00％,93.88％,70.00％ and 93.88％ when SEP latency extended beyond 10％.The sensitivity,specificity,positive predictive value,and negative predictive value of MEP in predicting intra-operative cerebral hypoperfusion were 30.00％,97.96％,75.00％,and 87.27％ when MEP amplitude declined beyond 50％.Decline of SEP and MEP amplitudes and extension of SEP latency have positive correlations with TCD.ROC indicated that the amplitude of somatosensory evoked potentials could predict intraoperative hypoperfusion when it decreased by 51.0％ than the baseline monitoring value after carotid artery occlusion,with sensitivity of 100.0％,specificity of 89.8％ and area under the curve of 0.918 (95％CI:0.846～0.990,P=0.024).ROC also showed that the latent phase of somatosensory evoked potentials could predict intraoperative hypoperfusion when it was prolonged ＞9.8％ compared to the baseline monitoring value after carotid artery occlusion,with sensitivity of 100.0％,specificity of 92.9％and area under the curve of 0.941 (95％CI 0.878～0.995,P=0.014).Conclusion Evoked potentials can real-time monitor intra-operative cerebral hypoperfusion continuously in carotid endarterectomy,enjoying high sensitivity and specificity;in addition,decline of SEP amplitude and extension of SEP latency have higher sensitivity than MEP.
