Objective To explore the influence factors in hematoma formation after removing benign breast lesions with an ultrasound-guided vacuum-assisted system.Methods A total of 232 females with 312 benign breast masses received excisional biopsy with ultrasoundguided vacuum-assisted system.The pathology of patients,results of hematoma development and outcome,influence factors for hematoma occurrence(nodule size,nodule location,number of nodule,breast shape,menstrual period,efficacy time of bandage,and application of hemostatic agents during the procedure) were recorded.Results Pathologic examination revealed fibroadenomas in 138 lesions,fibroadenosis in 127 lesions,intraductal papillomas in 39 lesions,inflammatory change in 4 lesions,retention cyst of the breast in 3 lesions,and benign phyllodes tumor in 1 lesion.Thirty hematomas were observed in patients(9.6%).Finally,97.0%hematomas were absorbed completely within 6 months follow-up.The incidence rates of hematoma were increased by 24.7%,10.0%,63.2%,13.9%in the nodule diameter larger or equal to 25 mm group,removal of larger or equal to two nodules once time from one patient group,menstrual period group,and larger and loose breast group,respectively(all P<0.05).However,the incidences were decreased by 60.6%in the bandage performed for 12-24 hours or beyond 24 hours group(P<0.05).The multiple logistic regression models revealed that nodule size(x^2=15.227,P<0.001),number of nodule(x^2=7.767,P=0.005),menstrual period(x^2=24.530,P<0.001),and breast shape(x^2=9.559,P=0.002) were independent risk factors associated with hematoma occurrence,but efficacy time of bandage was a protective factor associated with hematoma occurrence.Conclusion The occurrence of hematoma after the minimally invasive operation was associated with nodule size,number of nodule,menstrual period,breast shape,and efficacy time of bandage. 展开更多

Morel-Lavallée Lesions (MLL), described in 1863 by French surgeon Victor-Auguste-Francois Morel-Lavallée, are rare posttraumatic closed degloving injuries, occurring as a result of tangential sheer forces, in which the skin and subcutaneous tissue separate abruptly from the underlying deep fascia, causing fluid collection with liquefied fat. A 31-year-old policeman involved in a road traffic accident, presented with a gradually expanding lumbar swelling, which was soft, fluctuant and painful with contused skinon examination. Computed Tomography (CT) scan of the lumbar spine revealed a large subcutaneous hematoma on axial view, extending from the 12th thoracic vertebra down to the first sacral vertebra. There was no skeletal lesion. The treatment consisted of surgical excision/drainage of the collection followed by continuous suction with drainage tubes for two days. The collection is completely resolved;the patient made a full recovery and has been asymptomatic. Since there was a history of blunt trauma and given the nature and the location of the collection over osseous prominences, we report this rare case of a large posttraumatic lumbar hematoma diagnosed on clinical and CT scanning grounds as a Morel-Lavallée lesion. The patient was informed that non-identifying information from the case would be submitted for publication, and he provided consent. 展开更多

目的分析肾上腺囊肿和血肿等非肿瘤性囊性病变的临床特点。方法回顾性分析2000年1月—2009年10月在上海交通大学医学院附属瑞金医院泌尿外科经过手术切除的肾上腺肿块标本共1250例,收集其中46例(3.68%)经过病理检查证实的单纯性肾上腺... 目的分析肾上腺囊肿和血肿等非肿瘤性囊性病变的临床特点。方法回顾性分析2000年1月—2009年10月在上海交通大学医学院附属瑞金医院泌尿外科经过手术切除的肾上腺肿块标本共1250例,收集其中46例(3.68%)经过病理检查证实的单纯性肾上腺囊肿和血肿的病例进行重点分析。术前患者均进行了内分泌功能检查和影像学(B超、CT、MRI和腹部平片加静脉肾盂造影)检查,术后进行病理诊断。结果 46例患者术前内分泌功能检查均无异常。术前影像学诊断30例(65.2%)为肾上腺囊肿,16例(34.7%)肿块性质不能确定。术中显示,肿块大小3.0cm×2.5cm~7.6cm×8.7cm;其中单纯肿块切除41例,肿块加肾上腺部分切除5例。所有患者术后随访8个月~9.5年,均未见复发。结论单纯性肾上腺囊肿经临床、影像学和实验室检查后大多可明确诊断,但部分肾上腺囊肿和肾上腺血肿易误诊为肾上腺实性肿瘤。具有症状的肾上腺囊肿或者性质不明的囊性肿块应行探查;无法明确病变性质的囊性肿块,需按静止性嗜铬细胞瘤做术前准备。 展开更多
