OBJECTIVE: To demonstrate the effectiveness of operative resection for patients with huge hemangioma. METHODS: Eight cases were adopted in this study, including 5 males and 3 females. Among them, 5 cases with hemangioma on the face and neck, 1 case on the back, 1 case on the buttock, and 1 case on the leg. The maximal size of the hemangioma was 31.2 cm x 9.1 cm and the minimal size was 27.3 cm x 6.0 cm. Before operation, angiography was taken to find out the size of tumor. During operation, intervention-embolism and circumferential suture were carried out to control bleeding so that resection of tumor was practicable. RESULTS: There had been successful result in all the cases with huge hemangioma. No recurrence were found with following up 8 months to 4 years(averaged 13 months). CONCLUSION: Angiography of the hemangioma is important in providing the informations for the operation design. The intervention-embolism and circumferential suture can control and reduce the bleeding in operation. Combine of these techniques is essential for the treatment of huge hemangioma.
Objective To evaluate safty and effects of a single photodynamic therapy(PDT) for circumscribed choroid hemangiomas. Methods We performed a retrospective analysis of 11 eyes of 10 patients who were reated with single standard PDT. Of 10 patients, 6 males, 4 females；mean 40 .2 years old；of 11 eyes, 6 left eyes, 5 right eyes; 1 patient who both eyes wer e involved. Follow-up time varied from 1month to 14months, mean 6.2 month. Results After treatment, all tumors show various degrees of regression and subretinal fluid were absorbed completely or partly. The visual acuity of 8 eyes improved; that of 3 eyes unchanged. Conclusions PDT is effective modality for circumscribed choroid hemangiomas. (Chin J Ocul Fundus Dis,2008,24:111-113)
ObjectiveTo observe the clinical effect of prolonged photodynamic therapy (PDT) irradiation time combined with intravitreal injection of ranibizumab in the treatment of circumscribed choroidal hemangioma (CCH).MethodsA retrospective clinical study. From March 2012 to March 2018, 51 eyes of 51 patients diagnosed in Shenzhen Eye Hospital were included in the study. Among the patients, the tumor of 36 eyes were located in macular area, of 15 eyes were located outside macular area (near center or around optic disc). All patients underwent BCVA, color fundus photography, FFA, ocular B-scan ultrasonography and OCT examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. OCT showed 48 eyes with macular serous retinal detachment. of 36 eyes with tumor located in macular area, the logMAR BCVA was 0.05±0.05, the tumor thickness was 4.5±2.2 mm, the diameter of tumor was 9.7±3.6 mm. Of 15 eyes with tumor located outside macular area, the logMAR BCVA was 0.32±0.15, the tumor thickness was 3.8±1.4 mm, the diameter of tumor was 7.7±1.9 mm. PDT was performed for all eyes with the irradiation time of 123 s. After 48 h, all patients received intravitreal injections of 0.5 mg ranibizumab (0.05 ml). At 1, 3 and 6 months after treatment, the same equipment and methods before treatment were used for related examination. BCVA, subretinal effusion (SRF), tumor leakage and size changes were observed. BCVA, tumor thickness and diameter before and after treatment were compared by t test.ResultsAt 6 months after treatment, the tumor was becoming smaller without scar formation. FFA showed that the blood vessels in the tumor were sparse compared with those before treatment, and the fluorescence leakage domain was reduced. OCT showed 43 eyes of macular serous detachment were treated after the combined treatment. The logMAR BCVA were 0.16±0.15 and 0.55±0.21 of the eyes with tumor located in or outside macular area, respectively. The difference of logMAR BCVA between before and after treatment was significant (t=－2.511, －2.676; P=0.036, 0.040). Both the tumor thickness (t=3.416, 3.055; P=0.011, 0.028) and diameter (t=4.385, 4.171; P=0.002, 0.009) of CCH patients were significantly reduced compared with that before treatment.ConclusionThe tumor of CCH can be reduced by prolonged PDT irradiation time combined with intravitreal injection of ranibizumab.
ObjectiveTo explore the clinical features, diagnosis, differential diagnosis, pathological characteristics, management and prognosis of airway hemangioma, and improve the level of the diagnosis and therapy.MethodsThe clinical data of a patient with airway hemangioma admitted to West China Hospital of Sichuan University were retrospectively analyzed. The related literatures were reviewed. Databases including PubMed, Ovid Medline, Embase, VIP, Wanfang and Chinese National Knowledge infrastructure were searched using the keywords as " Trachea” OR " Bronchus” AND " Hemangioma” from January 1976 to October 2016.ResultsThe patient was a 32-year-old male presented with hemoptysis and backache more than 10 days. His enhanced chest CT scan revealed thickening of the esophagus wall and narrowing of the lumen of esophagus. A wide range of vascular tumor like changes in the trachea and the two sides of bronchus were found by the fiberoptic bronchoscopy and gastroscope examination suggested esophageal varices. Although the patient had a wide range of airway lesions, the symptom of hemoptysis was relieved after the conservative treatment. The patient’s condition was stable until now. From January 1976 to October 2016, a total of 34 related articles were retrieved and 36 cases of airway hemangioma were reported. The etiology of the disease remains unknown. Recurrent hemoptysis was the common symptoms of airway hemangioma, and imaging changes lacking characteristics. Histopathological examination revealed dilated, thin-walled and different size of vascular or hyperplastic capillary and immunohistochemical staining was positive for vascular endothelial cell specific CD34 and Ⅷ factor.ConclusionsHemangioma is a common benign tumor of head and neck in infants and children. Hemangioma is very rarely occurred in trachea in adults. Clinical and imaging manifestations are not specific, and diagnosis relies on histopathological examination. Fiberoptic bronchoscopy and three dimensional reconstruction of thoracic vessels with CT play important roles in the whole process of diagnosis and treatment of airway hemangioma. It should be differentiated from lymphangioma. The prognosis of airway hemangioma is good.
Objective To observe the influences of estradiol (E2), basic fibroblast growth factor (bFGF), and tamoxifen (TAM) on the proliferation of hemangioma vascular endothelial cell (HVEC). Methods Two strawberry hemangioma from 2 infants (case 1 and case 2) were prepared for HVEC culture. The HVEC on passage 3 were cultured in estrogenfree improved minimum essential medium (IMEM) and subjected to various treatments with 100 pg/ml 17-β-E2, 10 ng/ml bFGF, and 1×10-6 mol/L 4-OH-tamoxifen(4-OH-TAM). The experiment was divided into 5 groups: group 1(IMEM, control group), group 2(17-β-E2), group 3(bFGF), group 4(17-β-E2／bGFG) and group 5(17-β-E2／bGFG／4-OH-TAM). The cell count(CC) and DNA proliferation index (PI) were determined. Results Two cases of HVEC were successfully cultured in vitro. The HVEC showed cobblestoneslike under microscopy and factor Ⅷrelated antigen(also named as von Willebrand factor，vWF) was positive by immunochemical staining. At 9 days in case 1: CC and PI remained unchanged in the control group; CC and PI were slightly increased in group 2, being 1.4 and 1.6 times as much as those in the control group respectively (P＜0.05); CC and PI significantly increased in group 3, being2.6 and 2.3 times as much as those in the control group respectively (P＜0.01); CC and PI increased remarkably in group 4, being 3.7 and 2.9 times as much as those in thecontrol group respectively (P＜0.01); CC and PI were down to the levels of controls in group 5(P＞0.05). The results in case 2 were similar to those in case 1. Conclusion In vitro, the promoting effect of bFGF on HVEC proliferation is much ber than that of estrogen. Estrogen and bFGF enhance this proliferation in a synergistic manner, which can be inhibited by tamoxifen.
Objective To investigate the value of indocyanine green angiography(ICGA) in evaluating circumscribed choroidal hemangiomas. Methods Color photography,funds fluorescein angiography(FFA) and (ICGA) were performed in 10 caese (10 eyes) of circumscribed choroidal hemangiomas. Results Among 10 affected eyes examined in this series,the tumors were better defined in this series,the FFA in 8 of them.ICGA showed the tumors were composed of irregular choroidal vasculature in earlyphase (1-5 seconds) of ICGA and quot;washed outquot; phenomenon in late phase of ICGA in all of 10 affected eyes.An adjacent disturbances of choroidal circulation in a sector downstream from the tumors in 9 eyes. Conclusion ICGA is useful in diagnosis and differential diagnosis of circumscribed choroidal hemanfiomas and helpful in the laser photocagulation treatment of the tumor.

OBJECTIVE To discuss the methods selection on treatment of body surface hemangioma. METHODS From February 1983 to March 2001, 265 patients with different types of body surface hemangioma were treated with prednisone in 94 cases, laser in 102 cases, and plastic surgery operation in 69 cases respectively. RESULTS Followed up 6 months to 15 years, 70 cases with prednisone treatment were cured (74.5%), which meaned the hemangioma was totally removed and no recurrence in 6 months follow-up, 51 cases with laser treatment were cured (50%), while in the plastic surgery operation group, the cure rate was 98.6% (68 cases). CONCLUSION Treatment with prednisone, laser or plastic surgery operation are all effective to body surface hemangioma and proper treatment method should be selected according to different period and different type of hemangioma to improve the therapeutic effectiveness.
Objective To investigate the therapeutic effects of retinal angioma. Methods The clinical data of 16 cases(20 e yes) were retrospectively analyzed, and the patients included 5 males and 11 females of 23.3 yeras old on average. Four cases in this series affected by bilateral retinal angiomas were identified as von Hippel-Lindou disease. The retinal an giomas were divided into 5 stages according to their degrees of developmnet from simple angiom without vessel dilation to feeder vessel dilation and intraretina l exudates, local retinal detachemnt, massive retinal detachment and complication occurrence in proper order. The methods of treatment were laser photocoagulati on, trans-scleral cryotherapy and vitreoretinal surgery. The patinets were followed up for 37.8 months on average. Results There were 10 eyes (2 in stage 1, 7 in stage 2, 1 in stage 3)treated with laser photocoagulation, and all of the angiomas were controlled after the treatment. The visual acuity im proved in 2 eyes, decreased in 4 eyes, and remained unchanged in 4 eyes. Cryothe r apy was performed on 7 eyes(5 in stage 3, 2 in stage 4). The visual deteriortion was found in 5 eyes; and the state of illness was stable in 3 eyes in stage 3 a nd aggravating in 4 eyes (2 in stage 3, 2 in stage 4). Vitreoretinal surgery was performed on 4 eyes including 2 which had been given photocoagulation, and the visual acuity improved in 2 eyes, decreased in 1 eye, and was unimproved in 1 ey e . The visual acuity decreased to no light perception in an untreated eye after 1.5 year follow-up. New angiomas occurred in 3 eyes with Von Hippel-Lindou disease in the follow-up period. Conclusion Laser photocoagulation is effective in treating the angiomas from stage 1 to 3. Cryotherapy can cause massive exudation and proliferation, and it is only suitable for a few patients in stage 3. The visual prognosis is more favorable in vitreoretinal surgery tha n other therapies for the patients in stage 4. (Chin J Ocul Fundus Dis, 2001,17:296-298)
Objective To explore the clinicopathological features and misdiagnosed causes of choroidal hemangioma. Methods Seven misdiagnosed cases(7eyes) of choroidal hemangioma,which were enucleated,were analysed retrospectively. Results One of the 7 cases was misdiagnosed as absolute phase of the secondary glaucoma,and 6 of them as choroidal melanoma before the enucleation.The majority of cases in this series manifested themselves clinically and pathologically in progressive loss of visual acuity and a flat elevated tumor located at the posterior ocular fundus near the optic disc and associated with exudative retinal detachment.And also there were occasionally small focal or linear pigmentary deposites obser ved on the surface of the neoplasm. Conclusion A flat elevated discoid tumor in the posterior fundus with extensive exudative retinal detachment might be a clinicopathological feature of the choroidal hema ngioma.
