Hemangioma of the Prostatic Urethra: Hematospermia and Massive Postejaculation Hematuria with Clot Retention

The case of a 53-year-old man with hematospermia and massive postejaculation hematuria that caused urinary retention is described. This is the sixth case in the English and Japanese language literature. Cystourethroscopic examination revealed that a solitary raised tumor was present just distal to the vermontanum, and that bleeding was from its apex. Histologic examination of an excisional biopsy sample showed features compatible with hemangioma.     

肝门胆管癌的外科治疗60例临床分析

肝门胆管癌近年有增多趋势,本文报告我院1975年～1985年间肝门胆管癌60例,占全部肝外胆管癌82例之73.1％,占同期全部胆道手术3626例之1.65％。临床表现主要有三型:1)阻塞性黄疸29例,其中25例曾误诊为肝炎;2)急性胆管炎12例;3)长期胆道疾病14例,其他5例。本组行B超检查19例,ERCP10例,PTC39例。最后诊断根据PTC和/或ERCP,剖腹术及病理检查结果。 56例施行了手术治疗,仅6例施行肿瘤连同半肝切除,姑息性肝胆管内引流15例,外引流23例,其他方法12例。平均存活时间:6例切除组24.5月,48例姑息手术组8.7月,未手术的4例为5月。文中强调早期诊断,凡40岁以上出现阻塞性黄疸或“传染性肝炎”均须警惕胆管癌,进行B超,CT,ERCP或PTC检查,文中强调PTC是诊断本病重要手段,可选择进行右左肝管PTC。本病应争取手术切除,不能切除者行肝胆管内引流或外引流,二者疗效无明显差别。     

Successful Treatment of Kasabach-Merritt Syndrome with Prednisone and Epsilon-Aminocaproic Acid

The Kasabach-Merritt syndrome is characterized by thrombocytopenia and localized coagulopathy associated with a hemangioma. Most techniques applied to eradicate the tumor or accelerate its involution (surgery, radiation therapy, embolization) are invasive and require transfusion of large amounts of blood products. In some cases, medical treatment is the only alternative. Efficacy of steroids and antifibronolytic agents has already been described, but even this approach is associated with the administration of blood products. We report two cases of infants with Kasabach-Merritt syndrome associated with cardiac and hepatic hemangiomas. At admission, both had signs of cardiac failure. They were successfully treated with prednisone and epsilon-aminocaproic acid (EACA). Blood products were not required once the diagnosis was made. These observations have important implications for the management of patients with Kasabach-Merritt syndrome because they show that even in severe cases blood transfusions can be avoided by the use of prednisone and EACA.     

MR-Guided percutaneous ethanol ablation of liver tissue in a .2-T open MR system: Preliminary study in porcine model

The purpose of this study was to test the feasibility of MR-guided percutaneous ethanol ablation of liver tissue on a .2-T open MR scanner. Needles were placed by MR guidance first into an ex vivo sheep liver and then into livers of three anesthetized pigs, and injection of 10 ml of 96% alcohol was performed. T1 fast low-angle shot (FLASH), T2 turbo spin echo (TSE), and T1 spin echo (SE) images were obtained after incremental volumes of injection. In one pig, simultaneous injection of saline into normal liver was also performed with subsequent pathological correlation. Ethanol-infiltrated liver was hypointense to liver on all sequences, whereas saline caused no tissue signal changes on T1 SE and either isointense or hyperintense changes on T2 TSE images. Pathological examination confirmed ethanol-induced acute liver changes as compared with the control. MR guidance of needle placement and monitoring of ethanol effects on liver tissue is feasible. This may have implications for potential MR-guided hepatic tumor ablation.     

12例肺血管瘤临床分析

总结我院12年来的12例肺血管瘤的资料,结合文献讨论了肺血管瘤的临床特点,如:女性多见,可有呼吸系统症状,X线多表现为孤立性病灶及生长缓慢等。准确诊断较难,手术治疗预后良好。应进一步加深临床对该病的认识。     

多发性颅骨内血管瘤一例报告并文献复习

目的探讨多发性颅骨内血管瘤的临床特征和预后。方法报告1例多发性颅骨内血管瘤病例,结合相关文献分析该疾病的X线、CT、MRI和DSA等临床特征,探讨治疗效果和预后。结果多发性颅骨内血管瘤临床上极为罕见,大约占所有骨肿瘤的0.2%。X线平片检查见整个颅骨内蜂窝状改变,CT、MRI显示颅骨溶骨性病变或糜烂并向颅内外发展,DSA造影病变无染色,病理显示大小不等的异常血管,骨结构异常以及出血征象。外科治疗效果不佳。结论多发性颅骨血管瘤为颅骨内破坏性病变,涉及整个颅骨的多发性颅骨血管瘤,外科治疗效果不佳。     

失去肝动脉血液供应后大鼠肝门部胆管周围血管丛变化的三维构像研究

目的 探讨完全失去肝动脉血液供应后，大鼠肝门部胆管周围血管丛（PBP）的形态学变化。方法 将SD大鼠随机分为两组，对照组仅游离胆总管、门静脉、腔静脉和肝总动脉，不做切断；实验组结扎肝动脉，并切断肝十二指肠韧带除门静脉以外的其它组织，阻断其它侧支血管对肝门部胆管的血液供应。术后应用计算机对大鼠肝门部组织切片进行PBP三维可视化构建，并对PBP内层微血管进行定量分析，对胆管壁组织进行病理学检查。结果 实验组肝门部胆管分叉部位PBP平面结构显示胆管扩张，胆管壁明显增厚，壁内微血管尖细，排列紊乱，内层微血管密度减低；PBP立体构像显示空间结构紊乱，不规则，微血管细小，管壁不均匀增厚。与对照组相比，实验组肝门部PBP内层微血管总数明显减少（P〈0．01），肝门部PBP内层微动脉数也明显减少（P〈0．05）。实验组肝门部胆管壁呈慢性增生性炎症改变。结论 失去含氧量高的动脉血液供应时，PBP形态结构将会发生一系列改变，胆管壁组织也将发生相应的病理变化。

Hepatic falciform artery

The hepatic falciform artery is an occasional terminal branch of the left or middle hepatic artery, and may provide an uncommon but important collateral route when the principal visceral arteries are occluded.     

Intercostal hemangioma

This paper presents a case of intercostal hemangioma, in which a complete surgical resection was accomplished based upon a tentative diagnosis provided by magnetic resonance imaging (MRI). A 27-year-old man visited our hospital for the evaluation of chest pain and shortness of breath after exertion. Computed tomography showed a soft tissue mass, 5.5×3.5 cm in size, arising from the right lateral 7th intercostal space. Dynamic MRI showed that the mass was enhanced rapidly in the early phase and that this early enhancement was maintained during the delayed phase, which was compatible with a diagnosis of intercostal hemangioma. The patient underwent surgery, and a complete resection of the tumor with the right 7th and 8th ribs and their intercostal muscles was accomplished. Histopathological examination confirmed the diagnosis of intramuscular hemangioma of the large-vessel type. Presently, 6 months after the operation, the patient is doing well, without any evidence of local recurrence.
