The risk factor of pulmonary artery catheterization was assessed in 392 critically ill patients. Major indications for catheterization in the operating room were marginal cardiovascular reserve, anticipated large fluid and blood loss, and hypotensive anesthesia. Immediate complications included cardiac arrhythmia, carotid artery puncture, and pneumotherax. Long-term complications included positive bacterial ...

In severely ill newborns conventional methods of umbilical artery catheterization sometimes fail to achieve a functioning intravascular line. In 18 of 19 such newborns requiring umbilical artery catheters for optimal management, successful catheterization was attained using a cutdown procedure on the umbilical arteries. Vascular perforation within the anulus umbilicalis, tunica ...

Central umbilical artery catheterization, currently a widely used procedure in neonatal intensive care units, is accompanied by a substantial risk of vascular complications. Unilateral skin necrosis of the buttock was the initially seen manifestation of vascular occlusion secondary to thromboembolic phenomena or direct vascular damage from central umbilical artery catheterization ...

Retograde arterial catheterization has been the standard approach to hemodynamic and angiographic evaluation of the left ventricle and systemic arterial system. An alternative approach--antegrade left heart catheterization--is reported that circumvents arterial puncture. During cardiac catheterization from the femoral vein in 18 children with normally related great arteries who had interatrial ...

The anatomy of the limbus and its relationship to the fossa ovalis were studied in 90 normal human hearts in an attempt to explain the clinical success of blunt trans-septal catheterization. Previously reported rates of patent foramen ovale (25-35% of adult specimens) were confirmed, well below the reported rate of ...

The echocardiographic findings in a 73-year-old woman with constrictive calcified pericarditis are presented. The diagnosis was confirmed by physical examination, chest X-rays and cardiac catheterization. The echocardiogram demonstrated abnormal motion of the interventricular septum and of the left ventricular posterior wall, multiple thickened echoes of the posterior pericardium, and a ...

Iliac and femoral arteries previously exposed to percutaneous catheterization were examined by angiography in conjunction with re-catheterization in 44 infants and children, most of them with heart disease. Frequency and extension of thrombotic changes were analysed, as well as the relationship between occurrence of thrombotic complications and age, haematocrit value, ...

Twenty-two hirsute women underwent percutaneous adrenal and ovarian vein catheterization to differentiate and localize excessive hormonal output. All studies were done under fluoroscopic control; catheter placement was verified by venography, and blood samples were withdrawn for hormonal analysis. The right ovarian vein was successfully sampled in 42 per cent of ...

Axillary arterial catheterization for intraoperative and postoperative monitoring was successful in 90% of 87 attempts. Complications occurred in nine patients; there were eight hematomas, one of which was extensive. In the ninth patient, radial pulsations disappeared but returned after the catheter was withdrawn. There were no sequelae in any of ...

A variety of complications of umbilical vessel catheterization in the newborn have been reported by earlier investigators. This paper describes a case in which umbilical artery catheterization probably gave rise to an aortic aneurysm. The histological findings suggested that the hypoxic changes in the aortic wall as well as the ...

Simultaneous Fick and duplicate dye cardiac outputs were done in 105 patients with various cardiovascular diseases during routine cardiac catheterization. Dye was injected into the pulmonary artery and sampled from the brachial artery. Nineteen patients had mitral and/or aortic valvular regurgitation. Eighty-four per cent of the duplicate dye cardiac outputs ...

Superselective catheterization is critical when treating acute gastrointestinal arterial bleeders. The author has been using a coaxial catheter system with excellent results. The technical aspects of two representative cases are discussed. This is a particularly valuable technique when dealing with the anomalous left gastric artery which supplies the left lobe ...

The frequency of, and the conditions which contribute to a reduction of the arterial peak flow to the calves after percutaneous catheterization of the femoral artery were studied by strain gauge plethysmography in 98 catheterizations of children aged 2-16 years. Marked, rapidly disappearing flow reduction, considered to be caused by ...

A patient had neonatal necrotizing enterocolitis (NNE), secondary to aortic thrombosis following umbilical arterial catheterization. The thrombus occluded the ostium of the inferior mesenteric artery. A review of cases reported in the literature with complications following umbilical arterial catheterization revealed four instances of NNE or NNE-like lesions due to thrombosis ...

The influence of percutaneous catheterization of the femoral vessels on the arterial peak flow (APF) and the venous emptying rate (VER) of the calves was studied with strain gauge plethysmography in 112 children 2-16 years of age, who underwent arterial (49 cases) or venous catheterization, mostly because of heart disease. ...

Catheterization of the aorta via the umbilical artery provides a convenient route for monitoring arterial blood pressure, for obtaining blood specimens for measurement of blood gas tensions and chemistries, and for the infusion of fluids and pharmacologic preparations in sick newborn infants. Use of this technique may be accompanied by ...

Percutaneous catheterization of the radial artery appears to be a simple and safe alternative to catheterization of the umbilical artery for monitoring critically ill neonates. This avoids the serious and potentially fatal complications associated with use of the umbilical arterial catheter, and it is also applicable to monitoring of neonates ...

Five life threatening complications of percutaneous femoral vein catheterization for hemodialysis (Shaldon Technique) are presented. They occurred over a period of five years during which 700 uneventful catheterizations were carried out. In three instances femoroiliac vein thrombosis occurred, and on one occasion this was complicated by pulmonary embolism. In two ...

Indwelling radial artery catheterization was performed on 20 infants. In only one patient was it unsuccessful. Mean duration of indwelling catheterization was 44.1 hours. Advantages of this procedure include constant availability of arterial blood gas sampling and blood pressure monitoring. It is a relatively safe procedure offering a low incidence ...

Central venous catheterization through the basilic vein and by infraclavicular puncture of the subclavian vein was compared in a trial with random allocation to 125 candidate patients. The catheters were inserted via the two routes with roughly equal success rates. Subclavian catheters were maintained better for the period required than ...

In a prospective study of 210 intravenous catheters and needles 31 (15%) swabs yielded 34 microbial isolates. Twenty-eight were "non-pathogenic" skin commensals and six were "pathogenic" organisms. Commensals were isolated predominantly from catheters left in situ for only a short time (up to two days) and pathogenic organisms most frequently ...

A detailed description is given of a technique for the introduction of cardiac pacing catheters using a percutaneous supraclavicular route through the subclavian vein. In 91 attempts there was only one failure and the frequency of complications was low. Surface landmarks for the procedure were easy to define precisely, and ...

A technique for the management of cardiac catheterization in children is described which combines axillary plexus block with basal sedation. The technique offers a quiet still arm with pronounced vasodilatation, permitting the use of larger catheters than usual, making sampling easier, and giving undamped pressure records. These factors, together with ...

<$O_ST_ABS>Authors' Synopsis<$C_ST_ABS>A comparatively simple method of catheterizing the "central venous space" and right side of the heart by percutaneous puncture of the axillary vein is described. The method has been attempted in 50 patients. It was successful in 45 cases. No significant complications have occurred in this small series.

Antegrade catheterization is the preferred approach to angioplasty and selective fibrinolysis of branches of the femoral artery. A simple method of antegrade catheterization beginning with a retrograde puncture and using a new catheter is described. The method can reduce the number of punctures and manipulations needed for selective antegrade catheterization ...

A patient is described in whom a large congenital aneurysm or diverticulum of the right atrium caused repeated attacks of supraventricular arrhythmia and a strikingly reduced cardiac output. The aneurysm, which contained a large thrombus, was demonstrated by preoperative angiographic examinations. At the time of operation, regular rhythm returned at ...
