Y Fléjou, E Roland, J Ecoiffier

The mechanisms leading to traumatic injuries of the heart and coronary arteries and the typical lesions found are analyzed in light of experience with a total of 21 cases from several centers. The indications for angiography are discussed. Early angiography may be used for the emergency verification of a valvular, coronary, or myocardial rupture after intensive treatment has stabilized the patient's condition; in such situations the relative indications for angiography versus immediate surgery must be determined. Delayed angiography may be used in the more usual situations in which clear, persistent anomalies of a clinical, electric, or radiologic nature are observed.

结合几个中心共21例的临床经验,分析了心脏和冠状动脉外伤性损伤的机制及典型病变。本文讨论了血管造影的适应症。早期血管造影可用于经强化治疗稳定患者病情后瓣膜、冠状动脉或心肌破裂的紧急确认;在这种情况下,血管造影和立即手术的适应症必须确定。延迟血管造影可用于更常见的情况,即观察到明显的、持续的临床、电学或放射学性质的异常。

Renal occlusion phlebography: applicability of the balloon catheters. 肾闭塞静脉造影术:球囊导管的适用性。
Pub Date : 1978-10-31 DOI: 10.1007/BF02552050
D Novak, J Weber

The technique of selective renal occlusion phlebography using Swan-Ganz or Dotter-Lucas balloon catheters is described. The Swan-Ganz catheter is introduced into the femoral vein with the aid of a Cordis introducer system. The Dotter-Lucas balloon catheter is inserted via the same route using a combination of either a Desilets-Hoffman or Edslab introducer, along with a Gebauer introducer. Occlusion of the renal vein is achieved by insufflation of the balloon with air or injection of saline or dilute contrast media into the balloon. Selective renal occlusion phlebography was performed in 116 patients in order to exclude renal vein thrombosis, to delineate poorly vascularized renal masses, to determine the venous involvement of a renal tumor, and to assess the patency of splenorenal shunts. Renal occlusion phlebography optimizes the retrograde opacification of the renal veins. It has value in the delineation of poorly vascularized renal masses and in the determination of the venous involvement of renal and retroperitoneal tumors, and it would seem to be the method of choice for demonstrating the patency of surgical splenorenal shunts. Further enhancement of venous opacification by the combination of temporary arterial vasoconstriction with angiotensin (pharmaco-occlusion phlebography) and venous balloon occlusion is useful in some cases.

选择性肾闭塞静脉造影技术使用Swan-Ganz或Dotter-Lucas球囊导管进行描述。Swan-Ganz导管在Cordis引入系统的帮助下引入股静脉。Dotter-Lucas球囊导管通过相同的路径插入,使用Desilets-Hoffman或Edslab引入器的组合,以及Gebauer引入器。肾静脉阻塞是通过向球囊内注入空气或向球囊内注入生理盐水或稀释造影剂来实现的。我们对116例患者进行了选择性肾闭塞静脉造影术,以排除肾静脉血栓形成,描绘血管化不良的肾肿块,确定肾肿瘤的静脉受累情况,并评估脾肾分流的通畅程度。肾闭塞静脉造影术优化肾静脉逆行混浊。它在描述血管化不良的肾肿块和确定肾和腹膜后肿瘤的静脉受累方面具有价值,并且它似乎是证明手术脾肾分流通畅的首选方法。暂时性动脉血管收缩联合血管紧张素(药物闭塞静脉造影)和静脉球囊闭塞进一步增强静脉混浊在某些情况下是有用的。

Pericardial calcification in childhood. 儿童期心包钙化。
Pub Date : 1978-10-31 DOI: 10.1007/BF02552054
R L van der Horst

Calcific constrictive pericarditis (CCP) in a three-year-old child with symptoms of cardiac compression was confirmed by cardiac catheterization and angiography. Histologic examination of the pericardial tissue removed at operation revealed a tuberculous etiology. Though unusual in the pediatric age group, constrictive pericarditis (CP) may occur in children, most often as a complication of tuberculosis. Pericardial calcification may also develop in children with CP, though this too is rare. The diagnosis of CCP can be established by cardiac catheterization and angiography. Pericardiectomy is the definitive treatment.

钙化缩窄性心包炎(CCP)在三岁儿童心脏压迫的症状被证实心导管和血管造影。手术切除的心包组织的组织学检查显示为结核性病因。虽然在儿童年龄组不常见,但缩窄性心包炎(CP)可能发生在儿童中,最常作为结核病的并发症。心包钙化也可能发生在CP患儿身上,尽管这种情况也很少见。CCP的诊断可以通过心导管和血管造影来确定。心包切除术是最终的治疗方法。

The size of the aortic arch: a suitable criterion for differentiating between congenital heart diseases with left-to-right shunt? 主动脉弓大小:鉴别左向右分流先天性心脏病的合适标准?
Pub Date : 1978-10-31 DOI: 10.1007/BF02552046

A retrospective study was carried out to determine whether aortic arch size can be regarded as a reliable criterion for differentiating between congenital left-to-right shunt defects. The PA and AP plain chest films of children of all age groups with ductus arteriosus persistens (DAP) (n = 91), atrial septal defect (ASD) (n = 86), ventricular septal defect (VSD) (n = 87) and a normal control group (n = 387) were used to measure the size of the aortic arch, and an aortic index (AI) was calculated from aortic arch size and the height of the eighth thoracic vertebral body. Three age classes were defined from the AI values of the control group, and the diagnostic groups in each age class were compared with each other. Enlargement of the aortic arch, as reflected in an elevated AI value, was found most frequently in DAP cases. The size of the aortic arch is, however, of varying differential diagnostic value, depending on the age group. No correlation was found between aortic arch size and the size of the left-to-right shunt in cases of DAP.

我们进行了一项回顾性研究,以确定主动脉弓大小是否可以作为区分先天性左向右分流缺陷的可靠标准。采用持续动脉导管(DAP) (n = 91)、房间隔缺损(ASD) (n = 86)、室间隔缺损(VSD) (n = 87)及正常对照组(n = 387)各年龄组儿童的PA、AP胸部平片测量主动脉弓大小,并根据主动脉弓大小和第8胸椎体高度计算主动脉指数(AI)。根据对照组的AI值定义3个年龄组,并对各年龄组的诊断组进行比较。主动脉弓增大,如AI值升高所反映,在DAP病例中最常见。然而,主动脉弓的大小在不同年龄组有不同的鉴别诊断价值。在DAP病例中,主动脉弓的大小与左至右分流的大小没有相关性。

The early radiologic findings in the adult chest after cardiopulmonary bypass surgery. 体外循环手术后成人胸部早期影像学表现。
Pub Date : 1978-10-31 DOI: 10.1007/BF02552045
R W Katzberg, G H Whitehouse, J A deWeese

Postoperative chest radiographs of 70 adults who had undergone cardiopulmonary bypass surgery were evaluated. The distribution of pulmonary collapse/consolidation and pleural effusions, and the pattern of radiopacities related to drainage tubes were considered. Radiologic manifestations related to sternotomy were noted. Cases with a recorded postoperative blood loss of more than 280 ml/hour and/or an increase in mediastinal width of more than 70% had massive mediastinal hemorrhage that required reoperation. Changes in mediastinal contour were inconsistent, although total loss of mediastinal definition suggested hemorrhage or drainage tube blockage. A left apical extrapleural cap indicated massive mediastinal hemorrhage.

本文对70例接受体外循环手术的成人术后胸片进行了评价。考虑肺塌陷/实变和胸腔积液的分布,以及与引流管相关的放射性阴影的模式。记录了胸骨切开术的影像学表现。术后出血量大于280毫升/小时和/或纵隔宽度增加超过70%的病例为纵隔大出血,需要再次手术。纵隔轮廓的改变不一致,纵隔轮廓的完全丧失提示出血或引流管堵塞。左胸膜外帽显示大量纵隔出血。

Patients with major hematologic disorders who have hypersplenism and alterations in their immune mechanism are subject to a higher incidence of bacteremia after embolization procedures. In certain instances, these infectious complications can be fatal. Medical splenectomy for hematologic disorders is sometimes complicated by massive splenic infarction and spontaneous rupture; spontaneous rupture appears to be a function of both infarct size and underlying infectious complications. Prophylactic measures can be employed to avoid these complications after interventional splenic embolization.

Value of a cinefluoroscopic assessment of the Lillehei-Kaster prosthetic heart valves. 电影透视评估Lillehei-Kaster人工心脏瓣膜的价值。

In order to assess the functioning of the pivoting disc of the Lillehei-Kaster prosthetic valve, a cinefluoroscopic technique using multiple angulations was developed. The disc was detected in 240 (99%) of the 242 valves studied (126 aortic, 107 mitral, and nine tricuspid valves). The maximal-opening angle of the disc was measured in 75% of the aortic but only 20% of the mitral valve prostheses in the 182 valve studies in which this was attempted. Prosthetic dysfunctions were suspected clinically in three aortic and three tricuspid valves and confirmed with the cinefluoroscopic technique. This cinefluoroscopic approach constitutes a rapid, noninvasive, and sensitive evaluation of the function of the Lillehei-Kaster prosthetic valve in the aortic position.

为了评估Lillehei-Kaster假体瓣膜旋转盘的功能,我们开发了一种多角度的电影透视技术。242个瓣膜(126个主动脉瓣,107个二尖瓣和9个三尖瓣)中有240个(99%)检测到椎间盘。在182个瓣膜研究中,75%的主动脉瓣测量到了瓣的最大开口角,但只有20%的二尖瓣假体测量到了瓣的最大开口角。临床上怀疑三个主动脉瓣和三个三尖瓣的假体功能障碍,并通过电影透视技术证实。这种电影透视方法对主动脉位置的Lillehei-Kaster人工瓣膜的功能进行了快速、无创和敏感的评估。

Impedance plethysmography: its limitations as a substitute for phlebography. 阻抗容积描记术:作为静脉造影术替代品的局限性。
Pub Date : 1978-10-31 DOI: 10.1007/BF02552049

Impedance plethysmography (IPG) was used to study 132 legs: 100 in normal volunteers not subjected to radiocontrast phlebography, seven in patients whose limbs were phlebographically normal, and 25 proven by phlebography to have deep venous thrombosis (DVT). There were no false positive IPG results when a maximum venous outflow of 0.2% was the discriminant. However, in the 25 legs with thrombosis in calf, popliteal, femoral, and iliac veins, clots were not detected by IPG in 44--51% of legs, depending upon the discriminant. These results, which are in agreement with data reported elsewhere, indicate that it is reasonable to use the IPG method as the sole diagnostic maneuver when the test result is clearly abnormal, but that if the result is not abnormal, a radiocontrast phlebogram is necessary.

阻抗体积描记术(IPG)用于研究132条腿:100条正常志愿者未做造影静脉造影术,7条肢体静脉造影术正常,25条静脉造影术证实有深静脉血栓形成(DVT)。当最大静脉流出量为0.2%时,IPG结果没有假阳性。然而,在小腿、腘静脉、股静脉和髂静脉血栓形成的25条腿中,44- 51%的腿未被IPG检测到血栓,这取决于区别。这些结果与其他地方报道的数据一致,表明当测试结果明显异常时,使用IPG方法作为唯一诊断方法是合理的,但如果结果不异常,则需要进行放射线造影剂静脉造影。
