摘要:目的:通過食管吞鋇造影及造影后CT平掃檢查提高梨狀窩瘺的診斷率。方法:平臥位左、右、前、后斜位和頭低足高位食管吞鋇后透視觀察有無鋇劑外漏后,行CT平掃檢查。掃描范圍上起口咽部,下至胸骨上窩,層距厚3 mm。掃描后圖像作多層面重建處理。結果:透視下見到瘺管3例,另3例經CT多層面重建隱約見到瘺管,但14例均可見漏出的鋇劑滯留影,可判斷瘺管的存在。結論:食管吞鋇造影及造影后CT平掃可提高對梨狀窩瘺診斷的敏感性和診斷率。Abstract: Objective: To improve the diagnosis rate of the pyriform sinus fistula by means of esphagogram and CT scan after esphagogram. Methods:To observe whether there is the leakage of barium by Xray check after barium swallowed in the five positions of body, followed by CT scan. The scanning ranges from oropharyngeal to Waterloo on sternum. The thickness is 3mm. The image is dealt with multidimensional reconstruction after the scan. Results:Among fourteen cases, the fistula can be seen in three, and be indistinctly seen after the multidimensional reconstruction of CT scan in the other three ones. All The fourteen cases show the trace of the leakage of barium, which helps to prove the existence of pyriform sinus fistula. Conclusions: Esphagogram and CT scan after esphagogram contribute the sensitivity of the diagnosis of pyriform sinus fistula, and improve the diagnosis rate.
ObjectiveTo investigate the clinical characteristics and surgical management of the familial exudative vitreoretinopathy (FEVR)-associated rhegmatogenous retinal detachment (RRD). MethodsRetrospective noncomparative case series. Thirty-three eye of 32 patients were diagnosed FEVR-associated RRD by Fluorescein fundus angiography. There were 26 males and 6 females. The male to female ratio is 4.3:1 with an average age of 19.35±8.83 years. The detection of best corrected visual acuity (BCVA), refraction status, fundus photograph and fluorescein fundus angiography(FFA)were underwent in all patients. FEVR was confirmedby FFA and positive family history. The BCVA, refraction status, morphology of retinal detachment, location, size and shape of retinal hole, presence and grade of proliferative vitreoretinopathy (PVR), and subretinal proliferation were recorded. ResultsAs for the refractive status, the scope of refraction was +2.0 D to-13.0 D andthe BCVA were range from light perception to 0.7. Atrophy holes which located at the temporal half were responsible for retinal detachment in all cases. Besides, horseshoe tears were noted in 6 eyes (18.18%), while macular tears were noted in 2 eyes of RRD (6.06%). The PVR greater than stage C2 was noticed in 10 eyes (30.30%), while subretinal proliferation was presented in 23 eyes (69.70%). ConclusionsMale predominance, juvenile onset and associated with moderate to high myopia are the main characteristics in FEVR-associated RRD. Atrophy holes at the temporal half and the subretinal proliferations were most commonly in FEVR-associated RRD. Detailed fuduns and FFA examination of the fellow eye should be undergone to avoid misdiagnosis.
Objective To observe the clinical features, the complications and treatment effects of intermediate uveitis. Methods The clinical data of 36 patients (66 eyes) with intermediate uveitis were retrospectively analyzed，including the clinical features, fundus fluorescein angiography (FFA) features, complications，treatment effects and prognosis. The patients, 21 males and 15 females, aged from 8 to 70 years，with the mean age of 34.8 years. There were 30 cases with bilateral lesions and 6 cases with unilateral lesions. Results The main clinical manifestation were vitreous opacity, peripheral retinal venous lesions, optic disc edema, macular edema and posterior subcapsular cataract. The results of FFA showed that peripheral retinal venous lesions, optic disc hyperfluorescence, cystoid macular edema and retinal vein staining. After the treatment, the visual acuity of 31 cases（60 eyes，90.9%) were improved, 4 cases（5 eyes，7.6%) were stable and 1 case（1 eye，1.5%) was worsening. The main complications were cystoid macular edema, posterior subcapsular cataract and vitreous hemorrhage which leads to visual damage. Conclusions Intermediate uveitis was a common bilateral and chronic progressive intraocular inflammation，the anterior vitritis, pars plana and peripheral retinal vascular changes were mainly involved. Early diagnosis and proper treatment may prevent the permanent visual damage.
