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 OCT angiography (OCTA) imaging features of isolated choroidal hemangioma (CCH).MethodsA retrospective case study. From January 2017 to February 2019, 18 CCH patients (18 eyes) diagnosed in the Affiliated Eye Hospital of Nanjing Medical University were included in the study. There were 13 males (13 eyes) and 5 females (5 eyes), with the mean age of 44.5 years. All the tumors were orange-red, with clear boundaries, located at the posterior pole or around the optic disc. OCTA was used to scan the 6 mm×6 mm of macular area or in the range of 6 mm×6 mm. After automatic image processing, the system provided the blood flow map of shallow capillary plexus, deep capillary plexus, outer retina and choroidal capillary plexus, as well as the corresponding structure en-face image and B-scan image.ResultsOCTA examination found that when the stratification line was adjusted to the periphery of the choroidal capillary layer, the blood flow map showed clear boundary of the tumor, and the blood vessels on the surface of the tumor presented a network crisscross with different thickness. B-scan image showed that the whole layer of retinal choroid at the tumor presented a dome-shaped uplift, and the neurocortical layer could be accompanied by thickening, subretinal effusion, exudation and splitting. En-face image showed that the boundary of the tumor was clear, the surrounding exudation was strong reflection in spots or patches, local pigmentation showed weak reflection, and the signal reflection was uneven.ConclusionOCTA can clearly show the vascular morphology on the surface of CCH.
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.
ObjectiveTo evaluate the clinical features of 18 cases of juxtapapillary capillary hemangioma.MethodsIn 18 cases of 18 cases of juxtapapillary capillary hemangioma,the clinical datd of 19 eyes,the results of funds fluorescein angiography(FFA) of 16 eyes ,and the follow-up observation of 7eyes were retrospectively analyzed.ResultsIn 18 cases,the sex retio of male and female is 1:2 with the average age of 28.9 years.Peripheral retinal angioma was found in 3 cases(4eyes). In19 eyes,thr center of hemangioma was located beyond the rim of optic,most of which was in inferotemporal quadrant of the optic (7/19) with the size of 1-2.5 disc diameter (DD).Most of the tumors were red in colour (12/19).In the result of FFA of 16 eyes ,wash-out at the late phase was found in 13 eyes.decreased acuity was found in all 7 cases that were followed up more than 12 months (including 5 cases treated by laser photocoagulation).retinal detachment did't occur in 6 cases without exudative retinal detachment after being follow-up for 54.5 months of the average term.ConclusionMost of the juxtapiallary capillary hemangioma are orange or red oval tumors.The center of hemangioma are located beyond the rim of the optic.The patients often complain gradually decreased visual acuity when they are in prime of their life with exudation and edema in different degree around the tumor,FFA is helpful for the diagnosis and differential diagnosis of this disease.(Chin J Ocul Fundus Dis，2004，20：1-4)
Objective To explore the changes in the serum Cu2+and the indexes for the liver pathology and biochemistry before and after the copper needle retained in the central veins of the rabbit ears. Methods Fortynine New Zealandrabbits were randomly divided into 5 groups: Group A (copper needles retained for 1 d), Group B (3 d), Group C (5 d), Group D (7 d), and Group E (the control group, without any copper needles retained). In each experimental group, there were 10 rabbits, and in the control group there were 9 rabbits. The rabbits in each group were arranged to have their venous blood drawn for determination of theCu2+concentration, and for observation on the changes in the liver biochemicalindexes for 5 times before and after the copper needles were retained in the central veins of the rabbit ears. At the same time, a piece of the liver tissue ineach rabbit was taken for examination of the pathological changes. All the liver samples were given the basic pathological examination; if the liver sample hadsome extraordinary pathological features, the specific pathological examinationwould be given, even using the transmission electron microscope. Results After the copper needles were retained in the central veins of the rabbit ears, the Cu2+concentration increased with the passing time. The concentrations in the groups were 1.40±0.49 μg/ml in Group A, 1.45±0.53 μg/ml in Group B, 2.01±0.40 μg/ml in Group C, 2.38±0.83 μg/ml in Group D, and 1.34±0.45 μg/mlin Group E, respectively. There was a statistically significant difference between Group D and Group E(P＜0.05). There were no significant changes in the ALT and AST levels when compared with those before the copper needles were retained(P＞0.05); however, there was a considerably positive correlation on 1st day (r=0.686, P＜0.05), 5th day (r=0.712, P＜0.05), and 7th day (r=0.768, P＜0.01) when compared with those after the copper needles were retained. The histological examination showed that aseptic inflammation subsided with the time in part of the liver. The Masson staining and the Ag staining showed that there were no obvious changes in the hepatic lobules, with no fibrosis of the liver tissues found under light microscope. Conclusion There are no obvious toxic and side effects on the rabbit liver after the copper needles are retained in its central veins.
Abstract： Objective To investigate the clinicopathological characteristics, improve the accuracy of clinical diagnosis， and reduce postoperative complications of thoracic hemangioma. Methods Clinical records of 9 patients with thoracic hemangioma who underwent surgical resection in West China Hospital of Sichuan University from January 2006 to August 2012 were retrospectively analyzed. There were 2 males and 7 females with their average age of 47.9±19.3 （18-71）years. Six patients underwent thoracotomy， 1 patient underwent complete video-assisted thoracoscopic surgery （VATS）， 1 patient underwent video-assisted mini-thoracotomy， and 1 patient underwent staged operations which were performed by neurological surgeons and thoracic surgeons separately. Imaging characteristics, intraoperative gross tumor features, and pathological characteristics of resected hemangioma specimens were analyzed. Clinical outcomes of different surgical strategies for the treatment of hemangioma were compared. Results Nine patients with thoracic hemangioma were included in this study. Imaging studies showed the tumor as a round-shaped mass in 66.7% （6/9） of these patients and a lobulated mass in the remaining 33.3% （3/9） patients. Magnetic resonance imaging （MRI） assessment was helpful for preoperative diagnosis of hemangioma， with T2 weighted imaging tumor enhancement as the main MRI feature. Thoracic operation time was 106.3±60.1 （60-192） min， and intraoperative blood loss was 91.1±43.7 （30-150） ml. All the patients were followed up for 3-6 years except 1 patient who was followed up for 1 month. None of the patients had hemangioma-related death， recurrence or metastasis during follow-up. Conclusions Thoracic hemangiomas are usually benign entities and often locate in the mediastinum. Surgical strategies should be determined by the size and location of the tumor as well as the surgeon’s technique level. VATS has the advantages of being minimal invasive, causing less intraoperative blood loss and shorter length of hospital stay for the treatment of hemangioma. Resection of a dumbbell-type hemangioma may need cooperation between neurological and thoracic surgeons.
Objective To study the cl inical features of infantile hemangioma and vascular malformation, to find out a proper strategy of deal ing with them. Methods From March 2000 to August 2007, 2 957 cases of infantile hemangioma and vascular malformation were treated, including 860 operative cases and 2 097 non-operative cases. There were 441 male and419 female patients in operation group, aging 6 months to 18 years (median 5 years). In 1 950 hemangioma patients of nonoperation group, there were 575 male and 1 375 female patients, aging 1 month to 14 years (median 6 months); in 147 vascular malformation patients of non-operation group, there 67 male and 80 female patients, aging 2 years to 17 years (median 7 years). In non-operative group, 147 vascular malformation patients and 1 525 infantile hemangioma patients were followed up without any medical intervention, while other 425 hemangioma patients recceived triamcinolone plus dexamethasone intralesional injection treatment. All the treatments and outcomes were recorded. Results Vascular malformation cases and infantile hemangioma cases presented totally different cl inical features. To the deadl ine of this study, 522 (34%) of 1 525 un-intervented hemangioma cases turned into involuted phase and 383 (90%) of 425 cases receiving triamcinolone plus dexamethasone intralesional injection treatment turned into involuted phase after injection treatment; no regression was noted in 147 cases of vascular malformation. The constituent ratio of infantile hemangioma in 860 operative cases was decreased gradually and the constituent ratio of vascular malformation was increased gradually as the age increasing. Conclusion Infantile hemangioma has a distinct l ife pattern. Except several specific cases need medical intervention for their special location or large ambit and unacceptable growth, most infantile hemangioma need no medical intervention. Most vascular malformations can not regress spontaneously, proper intervention is in need.
ObjectiveTo evaluate the clinical features and follow-up effect of treatment for retinal capillary hemangioma (RCH) of myopic disc.MethodsRetrospective case series studies. A total of 14 patients (15 eyes) diagnosed with juxtapapillary RCH (JRCH) at Peking Union Medical College Hospital and followed up for more than 12 months from January 2007 to December 2019 were included. Among these patients, there were 7 males (7 eyes) and 7 females (8 eyes) with the average age of 29.8 ±12.7 years. There were 6 isolated JRCH cases, all of which were monocular patients, including 1 case with a single peripheral RCH; 8 cases with von Hippel-Lindau disease, including 5 cases of binocular RCH. Out of 15 eyes, 6 eyes were merged with peripheral RCH. Three eyes were simply observed, and 12 eyes were treated with photodynamic therapy (PDT) alone or PDT combined with other treatments. The average follow-up time was 55.2 months. Its clinical characteristics and long-term treatment effects were analyzed.ResultsAt the first visit, among the 15 eyes, 3 eyes had visual acuity＜0.1, 5 eyes were 0.1-0.4, and 7 eyes were＞0.5. The endogenous and fixed exogenous JRCH were 12 (80%, 12/15) and 3 (20%, 3/15) eyes, respectively. The size of the tumor was 1/4 to 4 optic disc diameters (DD); the combined macular edema, epiretinal membrane, and macular hole were 11, 5, and 1 eyes, respectively. There were 3 eyes with tumor diameter less than 1 DD. The visual acuity at the first diagnosis was 0.6-1.0, and no treatment was given. The follow-up time was 12 months in 2 eyes and 120 months in 1 eye. At the last follow-up, his vision remained stable and the tumor did not enlarge. Six eyes with tumor diameter ranging from 1.0 to 2.5 DD, visual acuity was 0.06 to 0.6 at first diagnosis, accompanied by retinal exudation. 5 eyes were treated with PDT alone, and 1 eye was treated with PDT combined with anti-vascular endothelial growth factor drugs. The follow-up time was 12 to 84 months. At the last follow-up, the visual acuity improved or stabilized in 5 eyes and decreased in 1 eye. There were 6 eyes with peripheral RCH, including 4 eyes with retinal detachment, 2 eyes with epiretinal membrane, and 1 eye with vitreous hemorrhage. The visual acuity at the first visit was 0.02-0.6. All patients were treated with PDT combined with transpupillary thermotherapy, extrascleral drainage, and vitrectomy. The follow-up time was 12 to 132 months. At the last follow-up, all eyesight decreased.ConclusionsVisual decrease cause by JRCH often occurs at young adults. Bilateral JRCH are more common in patients with von Hippel-Lindau's disease. The tumor can cause retinal exudation, macular edema, epiretinal membrane and macular hole, resulting in gradual vision loss. PDT and/or combined anti-vascular endothelial growth factor drugs for medium sized JRCH with retinal exudation can maintain long-term vision stability. Patients with large JRCH or severe complications such as retinal detachment tend to have poor prognosis.
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.
