It was statistically significant( P

Objective To evaluate the treament of central retinal artery occlusion by thrombolysis infusion via super selective ophthalmic artery catheterization.Design Retrospective,observational case series.Participants 21 eyes of 21 patients with CRAO. Methods 21 patients with CRAO were diagnosed by stereoscopic color fundus photography and flouorescein fundus angiography, and were treated by urokinase infusion via super select ophthalmic artery catheterization seldinger technique.Main Outcome Measures Visual acuity and the postoperative complications.Results In the 21 patients,10 had showed the occlusion of ophthalmic arterial trunk by super selective internal carotid artery angiography,the others can be found the appearance of ophthalmic arterial trunk and all patients had undergone thrombolysis therapy successfully.Imaging times of central retinal artery before and after thrombolysis infusion treatment are 38.18?10.86 seconds,12.65?3.30 seconds(t=-11.89,P=0.000).Mean foflow-up time is 3.23?1.26 months.After the treatment,the visual acuity was more than 0.25 in 4 patients,improved to different extent in 9 and remained unchanged in 8. Conclusions Super selective arterial catheterization with thrombolysis for CRAO can improve the visual acuity of the patients,a speedy execution of all internal,neurological,and ophthalmology diagnostic measures;and a prompt therapy are necessary.

Objectives To investigate the significance of electronic bronchoscopy and bronchoalveolar lavage in diagno-sis and treatment in children with pulmonary mass lesion. Methods A total of 74 hospitalized children from January 2011 to June 2012 whose imaging examinations showed massive patchy shadow were examined and treated by electronic bronchoscopy and bronchoalveolar lavage. Their clinical data were retrospectively analyzed. Results The major cause for the massive shadow was infection according to electronic bronchoscopy examination (68/74, 91.89%), 65 cases of them were lobar pneumonia, 3 cas-es were pulmonary tuberculosis followed by 5 cases of foreign body (6.76%) and one case of pneumorrhagia (1.35%).The lower left lung was the most frequently seen site of infection, followed by lower right lung. The agreement between infection sites and imaging examination was 97.30%. Bronchoalveolar lavage fluid showed that the primary pathogen of lobar pneumonia infection is Mycoplasma pneumoniae (MP) (42/65, 64.62%). The highest detection rate of MP was found in preschool group and the detec-tion rate between different age groups indicated statistically significant difference (P<0.01). The imaging examination showed pulmonary lesions in 61.54%children with lobar pneumonia improved significantly in one week. The improvement rate of pul-monary lesions was higher in infected children with short duration (1-2 weeks, 90.91%) between disease onset and electronic bronchoscopy inspection than those with longer duration (2-3 weeks, 51.72% and >3 weeks, 35.71%) (P<0.05). Conclusions Electronic bronchoscopy and bronchoalveolar lavage play dual roles in etiological diagnosis and therapy in children with pulmo-nary mass lesion.

Objective To recognize the CT manifestations of benign metastasizing leiomyoma (BML).Methods Four cases of BML proved by pathology were retrospectively analysed.Among these, 2 cases were pulmonary BML,1 ease was leiomyomatosis peritonealis diseminata(LPD),and 1 case was combined with pulmonary BML and LPD.All of them were female,and had a history of hysterectomy,the average age were 45.The CT findings of them were analyzed.Results The CT of pulmonary BML in three cases showed multiple rounded,well-defined discrete nodules,0.2—2.0cm in diameter,random distribution,and no calcification in the nodules.No hilum or mediastinum lymphadenopathy,and no pleural effusion.There were no enhancement after intravenous contrast examination.The CT findings of LPD in two cases were many masses around the vena cava,abdominal aorta and/or iliac artery.The masses were 4— 5cm in diameter with smooth margin and homogeneous density.No lymph node or ascites were found.One case who got intravenous contrast enhanced CT scan showed significant enhancement of the lesions;another case who got PET CT study showed no significant tracer concentration.Conclusion When multiple metastasizing nodular lesions with sharp margin and homogeneous density were found in the lungs or abdomen,they should be considered the possibility of BML in women with hysterectomy history.
