296例胎膜早破的临床分析

以２９６例胎膜早破（ＰＲＯＭ）作为研究对象，并以３５０例无ＰＲＯＭ作对照，探讨ＰＲＯＭ对母婴的影响。结果显示：ＰＲＯＭ组难产率为５６．０８％，产褥病率４．０５％，早产率为５．４０％，胎儿窘迫率为１３．００％，新生儿窒息率为４．３３％，新生儿肺炎发生率为３．６６％，均明显高于对照组，统计学处理后有显著或极显著性差异（Ｐ＜０．０５，Ｐ＜０．０１）。而且，ＰＲＯＭ隐惹期小于２４小时的产褥病率为２．２９％；大于２４小时的产褥病率则为８．９７％（Ｐ＜０．０５）。本文提示，应积极预防胎膜早破，一旦出现胎膜早破，宜在６小时内使用抗生素预防感染，并加强母儿监测。     

Subkapsularës leberhämatom bei HELLP-syndrom

Zusammenfassung Das HELLP-Syndrom (Hemolysis, Elevated Liver enzymes, Low Platelets) tritt als Komplikation einer Schwangerschaftspräeklampsie auf und kann zu ausgedehnten subkapsulären Leberhämatomen führen. Wegen der Rupturgefahr der Hämatome besteht eine lebensbedrohende Notfallsituation für Mutter und Ungeborenes. Anhand von 2 Fallbeispielen wird das interdisziplinäre Vorgehen diskutiert. Mit Diagnosestellung der subkapsulären Leberhämatome sollte die notfallmäßige Entbindung durch Sectio erfolgen. Dann kann die chirurgische Entscheidung für eine konservative, abwartende Therapie mit Intensivüberwachung oder für eine Notfalloperation im Falle einer Leberkapselruptur ohne vermeidbares Risiko getroffen werden.

Subcapsular liver hematoma with HELLP-syndrome — an interdisciplinary urgency

Summary The HELLP-syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets), known as a complication during pregnancy, is associated with preeclampsia and may cause subcapsular liver hematomas. In case of hepatic rupture the lives of mother and unborn are threatened. Therefore, an interdisciplinary diagnostic and therapeutic approach is discussed and compared to two examples. The diagnosis of subcapsular liver hematoma must lead to urgent delivery through Cesarean section. Thereafter, the surgeon may decide between observation on an intensive care unit and urgent operation in case of hepatic rupture, without endangering the unborn.

     

Extensive replacement of the aorta from the ascending aorta to the supraceliac abdominal aorta during a one-stage operation

A successful replacement of the aorta from the ascending aorta to the supraceliac abdominal aorta in one operation is herein reported. The patient was 66-year-old woman who had DeBakey type I chronic aortic dissection with a pre-disseminated intravascular coagulation (DIC) condition. The image diagnosis revealed a markedly enlarged false lumen with a narrow true lumen in the ascending aorta extending to the diaphragm level while below the diaphragm level, the aortic dilatation was mild. The operation was performed through both a thoracoabdominal incision and a median sternotomy to expose the whole thoracic aorta, and the aorta was replaced from the ascending aorta to the supraceliac abdominal aorta. Selective cerebral perfusion was used for cerebral protection and this was a useful adjunct since no time limitations were thus required during repair of the aortic arch. Although the patient developed several complications postoperatively, she eventually recovered and was discharged from the hospital without any neurological disorders.     

INTRA-AORTIC BALLOON RUPTURE CAUSING FEMORAL ENTRAPMENT

Rupture of an intra-aortic balloon counterpulsator (IABCP) demands immediate removal. We report a case of thrombus formation within a Datascope IABCP secondary to IABCP rupture, necessitating surgical exploration for removal. There is a disturbing pattern of balloon ruptures with this type of IABCP.

挫伤性脉络膜破裂出血

应用荧光血管造影方法观察118例眼挫伤病人的眼底改变。其中46例(39.0％)有脉络膜破裂去血。46例中视盘附近脉络膜破裂出血26例(56.5％);黄斑部脉络膜破裂出血13例(28.3％),其余部位脉络膜破裂出血7例(15.2％),三者间差异非常显著(P<0.01)。视盘颞侧部位脉络膜破裂出血22例(47.8％),鼻侧部位18例(39.1％),其余6例为视盘的上、下或环周破裂出血。     

Angioarchitectural study of esophageal varices

Summary Pathomorphological and angioarchitectural characteristics of esophageal varices, mainly of ruptured varices, were studied in autopsy cases. Contrast medium was injected into the esophageal vein in 25 among 75 cases with varices, and in 4 cases without varices as a control. Out of the 75 cases with varices, rupture was confirmed in 8 cases. Ruptured points were recognized at the oral end of the longitudinal veins (these veins were called sudare-like veins in this study) in the lamina propria at the lower end of the esophagus in all of the 8 cases. This ruptured area was called the critical area. By morphometric examination, dilatation of these sudare-like veins was the most obvious in severe varices, and these veins were observed to penetrate the muscularis mucosae to connect to the submucosal veins at the critical area. This area seemed to be of the greatest significance in the pathogenesis of spontaneous variceal rupture.     

Branches of the splenic artery and splenic arterial segments

In 200 adult autopsy specimens, the arterial supply to the pancreas and spleen was studied radiologically and by manual dissection. The splenic artery divided into two or three lobar arteries, which supplied its corresponding lobe; each lobar artery subsequently divided into two to four lobular branches. Six to twelve lobular branches were observed entering the splenic substance at the hilum. Lobar arteries did not anastomose with each other, hence, the lobes of the spleen are also termed segments. The lobules, however, were not found to be independent segments and the arteries of one lobule anastomosed with those of other lobules. The branching pattern of the splenic artery varied from one specimen to another, so much so that a prevailing pattern could not be identified. Polar arteries, particularly to the superior pole, arose quite proximal to the hilum in 51% of cases and were occasionally missed. In 45% of males and 40% of females, the posterior gastric artery arose from about the middle of the splenic artery. The splenic artery was not found to be tortuous in fetuses, newborns, and young children. Tortuosity was seen in only 10% of adults; thus, the characteristic tortuosity of the splenic artery appears to develop with age.
