Venous hemangioma of the mesoappendix: Report of a case and a brief review of the Japanese literature

We present herein the rare case of a 48-year-old man in whom an abdominal mass, revealed by celiotomy to be a solid tumor of the mesoappendix, was histologically diagnosed as having a venous hemangioma. To our knowledge, only 18 cases of mesenteric hemangioma have been reported in Japan, including the present case. However, establishing a correct diagnosis preoperatively is extremely difficult despite advanced imaging techniques. In fact, a mesenteric mass was diagnosed preoperatively in only 3 of these 18 cases. Complete excision with or without bowel resection was performed in 16 cases. Interestingly, the histological diagnosis of all the previous cases was cavernous hemangioma, confirming that this report decuments the first case of venous hemangioma of the mesentery in the Japanese literature.     

完全性肺静脉异位引流的手术治疗经验

为评估影响完全性肺静脉异位引流（ＴＡＰＶＤ）手术纠治的因素，本组纳入了２８例在中度低温体外循环和１５例在深低温停循环下手术纠治者。结果手术死亡４例，死亡率９．３％。随访３２例，２例肺静脉回流梗阻分别于术后５个月和２年３个月死亡。结论认为，ＴＡＰＶＤ必须早期手术防止肺血管阻塞性病变；术后定期随访；改进手术方法，防止心房内补片粘连所致肺静脉回流梗阻。

目的 分析上矢状窦旁脑膜瘤致上矢状窦(SSS)阻塞时其侧支静脉通路的建立情况，确定其在肿瘤切除术中的意义。方法 总结归纳86例上矢状窦旁脑膜瘤行MRA及DSA检查时的静脉系表现。结果 27例发生SSS完全阻塞，59例部分阻塞。18例在阻塞的SSS周围出现了由表浅皮层静脉所形成的侧支静脉环；通过表浅皮层静脉与蝶顶窦及小脑幕静脉系建立端—端吻合的16例；通过与Troland或Labbe静脉建立吻合的14例；通过大脑镰与下矢状窦吻合的9例；通过脑膜静脉并经板障静脉引流到颈外静脉系的17例；混合型12例。结论 上矢状窦旁脑膜瘤致SSS阻塞时，肿瘤周围存在广泛侧支静脉通路，术中应注意保护。脑DSA及MRA检查对术前了解SSS通畅性及侧支静脉通路建立有帮助。     

完全性房室间隔缺损的外科治疗

目的回顾性总结手术治疗完全性房室间隔缺损的经验。方法112例病儿,≤6个月43例(38%,X组),>6个月69例(62%,Y组)。85例行心导管检查。Rastelli A型89例,Rastelli B型10例,Ras- telli C型13例。手术技术分单片法,双片法和简化单片法。术中经食管超声检查发现异常而即刻再次手术者7例(二尖瓣反流4例,二尖瓣狭窄2例,左室流出道梗阻1例)。术后入重症监护室,左房压8～21 mm Hg,中心静脉压7～12mm Hg。呼吸机平均应用47h,监护室平均滞留6.3d。结果室间隔缺损残余分流(直径>2mm)13例,二尖瓣中度反流12例,完全性房室传导阻滞4例。院内死亡6例(X组1例,Y组5例)。术后随访91例(81%),随访1～5年,平均2.3年。1例术后1年因肺炎心衰死亡,1例术后2年因二尖瓣中-重度反流而换瓣。结论院内死亡率提示,小于6月龄完全性房室间隔缺损病婴手术是安全的。随着年龄增大,瓣膜成形效果、肺动脉高压的预后可能会更差。双片法修补室间隔缺损较易发生残余漏(9例,18%),简化单片法出院时二尖瓣关闭不全发生率明显高于另外两种方法(6例,16%)。     

Characterization of an immunologic polymorphism (D79H) in the heavy chain of factor V.

BACKGROUND: During the study of a family with hereditary factor (F)V deficiency (FV Amersfoort, 1102 A > T in exon 7) we identified an individual with 5% FV heavy chain antigen (FV(HC)) and 50% FV light chain antigen (FV(LC)). Further testing revealed that apart from the FV Amersfoort allele a second variant FV allele was segregating in this family, which encodes for a FV molecule with a reduced affinity for mAb V-23 used in the FV heavy chain ELISA (ELISA(HC)). OBJECTIVE: Identification and characterization of the molecular basis responsible for the reduced affinity of the variant FV for mAb V-23. METHODS: Family members of the proband were screened for mutations in the exons coding for the heavy chain of FV, after which the recombinant variant FV could be generated and characterized. Next, the cases and controls of the Leiden Thrombophilia Study (LETS) were genotyped for carriership of the variant FV. RESULTS: In the variant FV allele a polymorphism in exon 3 (409G > C) was identified, which predicts the replacement of aspartic acid 79 by histidin (D79H). Introduction of this mutation in recombinant FV confirmed that it reduces the affinity for binding to mAb V-23. The substitution has no effect on FV(a) stability and Xa-cofactor activity. In Caucasians the frequency of the FV-79H allele is approximately 5%. Analysis of the LETS revealed that the FV-79H allele is not associated with FV levels (FV(LC)), activated protein C sensitivity (using an activated partial thromboplastin time-based test) or risk of venous thrombosis (OR 1.07, CI 95: 0.7-1.7). CONCLUSION: The D79H substitution in FV should be considered as a neutral polymorphism. The monoclonal antibody V-23, which has a strongly reduced affinity for FV-79H, is not suitable for application in diagnostic tests.
