目的:探讨儿童颅骨血管瘤的临床特点和手术治疗。方法:报告自2002年1月至2008年12月我院收治的3例儿童颅骨血管瘤病例,结合相关文献分析该疾病的临床表现,影像学特征,病理特点及治疗方法。结果:儿童颅骨血管瘤临床上极为罕见。影像学检查显示颅骨呈蜂窝状溶骨性改变并向颅内外生长。病理切片显示骨结构异常,并伴有大小不等异常血管增生及血栓形成。结论:颅骨血管瘤是一种侵蚀颅骨内外板的破坏性疾病。手术应早期进行,完整切除后,患者预后良好。
目的探讨肝血管瘤切除术中血流阻断方法的选择。方法回顾性分析我院收治的19例肝血管瘤患者的手术方式。结果全组均行手术切除，术中出血50～1 500 ml（平均312 ml）。 术中根据血管瘤所在位置选择不同肝血流阻断方法，其中行半肝血流阻断4例，运用Glisson蒂横断式肝切除术或其分段原理阻断Glisson系统分支6例，间断阻断第一肝门7例，预置肝上、下下腔静脉和第一肝门阻断带并间断阻断第一肝门2例。 术后5例并发右侧胸腔积液，均经保守治疗后好转，手术并发症发生率为26.3%（5/19）。 术后住院7～41 d（平均16.9 d），均治愈出院。12例患者获随访，随访0.3～2年（平均1.1年），术前有症状的8例患者症状均消失，无复发，1例残留肝内血管瘤（直径lt;2 cm）。结论肝血管瘤患者肝切除术中的入肝血流阻断应强调个体化，根据肿瘤位置及大小选择不同的阻断方法，使患者术中出血少，术后恢复快。
ObjectiveTo study the relationship between expression of Caspase-3 and regression of hemangioma. MethodsCaspase-3 expression was detected in 79 hemangiomas and 5 normal skin tissues by immunohistochemistry (SP). ResultsIn 79 hemangiomas, the positive rates of Caspase-3 expression in proliferating, involuting and involuted phases were 52.4%, 91.2% and 83.3%, respectively. The expression of Caspase-3 in involuted and involuting phases was higher than proliferating phase(Plt;0.05，Plt;0.01) and control group(Plt;0.01). There was no statistical difference between the latter two groups (Pgt;0.05). ConclusionCaspase3 is involved in the converting of hemangiomas from proliferating phase into involuting phase. The activation of Caspase-3 may induce apoptosis of endothelial cells, thus leading to the regression of hemagioma.
目的分析比较肝血管瘤不同栓塞剂的栓塞治疗结果，寻找更为理想、合理的方法。方法对12例肝血管瘤16例次经皮穿刺超选择性肝动脉插管行栓塞治疗，其中单纯碘化油栓塞2例次，碘化油+明胶海绵颗粒栓塞6例次，碘化油+聚乙烯醇（PVA）微球栓塞5 例次，碘化油+平阳霉素栓塞3例次。随访10~32个月。结果全部病例均取得较肯定的疗效，无并发症发生。碘化油+平阳霉素和碘化油+PVA微球两种方法疗效稳定，复发率低，优于前两种方法。结论肝动脉栓塞治疗肝血管瘤疗效肯定，几种栓塞剂中，碘化油+平阳霉素及碘化油+PVA微球最佳。
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.
Objective To improve the knowledge of pulmonary sclerosing hemangioma ( PSH)especially with bilateral multiple lesions of the lung. Methods The clinical data of 3 cases of PSH ( 1 case with bilateral multiple lesions in the lung) were analyzed, and the related literatures were reviewed. Results All of the 3 cases were females. A 22-year-old female patientwith bilateral multiple nodules in the lungs was complicated with thyroid multiple nodular goiter ( with hypothyroidism) , dysfunctional uterine bleeding ( with anemia) , nodular hyperplasia of the breast, and arteriovenous malformation over forearm. Thoracoscopicbiopsy of left lung and resection of the right pulmonary mass were performed and both the lesions were confirmed as PSH. The clinical manifestations of multiorgan diseases and the presence of PSH suggested Cowden syndrome in this patient. The other 2 cases aged 50 and 53 were asymptomatic with solitary pulmonary nodules identified incidentally. The accessory examinations for malignancies, infections, and autoimmune diseases showed no specific findings. Resection of the lesions were performed by thoracoscopic surgery and thoracotomy respectively, and the histopathological results proved to be PSH. Literature review showed that PSH typically occurred in middle-aged women without clinical symptoms and signs, often presenting as a pulmonary solitary nodule/mass identified incidentally. The differential diagnosis should include peripheral carcinoma, hamartoma, inflammatory pseudotumor and tuberculoma. Multiple PSH, which mainly presented as multiple well-defined nodules /masses of different size in the lungs, was rather rare, but easily confused with metastatic neoplasm. Lung biopsy by surgical operation was a common way to confirm the diagnosis, while FDP-PET and fine needle aspiration biopsy showed some defects. Surgical resection was an effective method of treatment, the residual lesions of multiple PSH should be monitored. Cowden syndrome may be considered if a PSH coexisting with abnormity of multiple organs such as thyoid, breast and vessels. Conclusions PSH should be considered during the differential diagnosis for solitary or multiple nodules /masses in the lung. Surgical biopsy is a common way to confirm the diagnosis. Local excision andnecessary follow-up are effective methods of treatment.
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.
