ABSTRACT
Abstract?AIM:To evaluate the efficacy of photocoagulation alone or combined with intravitreal Bevacizumab for radiation retinopathy ( RR) .?METHODS: There were 43 patients ( 43 eyes ) with RR were collected at the Fifth Affiliated Hospital Sun Yet-Sen University between Jan.2009 and Jan.2014.Twenty-one patients received the photocoagulation treatment combined with intravitreal bevacizumab and 22 patients received the treatment of photocoagulation alone.All the patients would complete ophthalmologic examinations, including best -corrected visual acuity ( BCVA ) , intraocular pressure, optical coherence tomography, fundus fluorescein angiography before and after the treatment.?RESULTS:BCVA:In monotherapy group, there were no statistically difference about BCVA before and after treatment ( P>0.05).In combined therapy group, the BCVA had been increasing gradually in 2wk, 1, 3, 6mo after treatment ( P 0.05).In the comparison of BCVA in these two groups in 2wk, 1, 3, 6mo after treatment, the combined therapy group were better than monotherapy group in each time point (P0.05).Central macular thickness (CMT):in monotherapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P 0.05).In combined therapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P0.05).In the comparison of CMT between these two groups in the 2wk, 1, 3, 6mo after treatment, those of combined therapy group were thinner and difference were statistically significant ( P 0.05).? CONCLUSION: Photocoagulation combined with intravitreal bevacizumab for the treatment of radiation retinopathy both have an effect on reducing the macular edema in a short time (6mo).But the long-term efficacy is poor.
ABSTRACT
ObjectiveTo introduction of perforator flaps,muscle flaps pedicled by descending branch of lateral circumflex femoral artery,method and their clinical application that multiple soft tissue defects of hand are repaire by muliplefoliated tissue flap only branch lateral circumflex femoral artery.MethodsFifteen patients with multiple soft tissue defects of hand were repaired muliplefoliated tissue flap only pedicled bydescending branch lateral circumflex femoral artery.At first,the anterolateral thigh perforator flap was designed and harvested according to the soft tissue defects of hand, then the descending branch lateral circumflex femoral artery was dissected at the same time the segmented perforator flap,fascia lata flap,rectus femoris muscle flap, vastus lateralis muscle flap, vastus intermedius muscle flap and distal spatium intermusculare flap were harvested in need according to distance among soft tissue defects.The muliplefoliated tissue flap was harvested only pedicled by descending branch lateral circumflex femoral artery, at last muscle flaps and fascia lata flaps were covered by skin graft, so the multiple soft tissue defects of hand were repaired in one time.ResultsNo vascular crisis happened. All skin grafts survived well, the contour of all repaired soft tissue defects was good and protective feeling was recovered by skin grafts of all flaps. All cases were got follow-up and the range was from 6 to 20 months(the average was 8.7 months).Wound of donor site healed well, muscle strength of quadriceps and motion of knee were normal. Three cases were excellent,nine cases were well and 3 cases were good, according to upper extremity function evaluation criteria of Chinese Medical Society for the Surgery of the Hand, the rate of good was 80 percent.ConclusionMultiple soft tissue defects of hand can be repaired by muliplefoliated flap only pedicled by descending branch of lateral circumflex femoral artery. Its advantages included reduction of operation time and treatment, good recovery of hand contour and function. It is a good method to repair multiple soft tissue defects of hand.
