目的:探讨鼻咽纤维血管瘤术前栓塞的应用价值。方法:17例鼻咽纤维血管瘤患者,单纯手术摘除10例,术前3天进行数字减影血管造影(DSA)检查及血管内栓塞术7例。结果:7例术前栓塞组术中出血200～700mL,平均430mL;输血0～550mL;10例单纯手术组出血550～1430mL,平均1200mL,输血350～1200mL。术前栓塞组出血量和输血量较单纯手术组显著减少。结论:术前瘤体栓塞治疗鼻咽纤维血管瘤是安全有效、理想的术前辅助治疗手段。
Radiofrequency ablation for hepatic hemangioma is safe and effective, and can obtain the same curative effect as traditional surgical resection. For hepatic hemangiomas with large volume, abundant arterial blood supply and long ablation time, systemic inflammatory response syndrome (SIRS) often occurs after radiofrequency ablation, which can lead to injury or dysfunction of important organs. This paper systematically summarizes the mechanism, prevention and treatment of SIRS after radiofrequency ablation of hepatic hemangioma, so as to provide reference for improving the safety of radiofrequency ablation of hepatic hemangioma.
Objective lt;brgt;To evaluate the clinical effect of transpupillary thermotherapy (TTT) on circumscribed choroidal hemangioma (CCH). Methods lt;brgt;The clinical data of 12 eyes of 12 patients with CCH treated with TTT were retrospectively analysed. Infrared diode laser Iridex, oculight SLX was used in TTT at 810 nm and power between 220 and 1000 mW with a beam diameter of 1.2 or 2.0 or 3.0 mm, with 1 to 2 minutes of exposure time. The visual acuity, subretinal fluid, complication ,thickness and hyperfluorescence of CCH were observed pre- and postoperatively in the treated eyes. The average period of follow-up was 10 months (6-16 months). lt;brgt; lt;brgt;Results lt;brgt;Among the 8 eyes with peripheral retinal detachment in 12 cases of CCH the peripheral subretinal fluid was completely absorbed in 6 eyes, and partially absorbed in 2 eyes after TTT treatment. In 8 patients undergone ultrasonography, the mean value of tumor thickness went down by 21.75 % in 7 eyes. The resultant visual acuity after treatment was improved in 3 eyes, maintained no change in 7 eyes and reduced in 2 eye. The fundus fluorescein angiography in 10 eyes revealed a significant decrease of the leakage in tumor. Postoperative complication of TTT in the 12 eyes included retinal hemorrhage (5 eyes) and retinal fold (1 eye). Conclusion lt;brgt;TTT is an effective treatment for CCH. lt;brgt; lt;brgt;(Chin J Ocul Fundus Dis, 2002, 18: 190-092)
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.
The authors suggest that occlusion of blood flow to the whole liver is not necesarily a routine procedure in surgical removal of giant cavernous hemangioma in the 8th segment of liver. An occlusion tape can be placed around the finferior vena cava inadvance. Separtion of inferior vena cava between the diaphragm and the upper surface of liver sometimes is difficult, so that placement of the tape may fail. The procedure which we performed in four patients was intermittent occlusion of blood flow at the first hepatic hilum at room temperature during dissection and removal of the tumor en bloc. This operative method is simple and safe as compared with that of resection of the 8th segment of liver.
