Intravenous digital subtraction pulmonary angiography was performed in 220 patients. Of these, 206 had suspected pulmonary embolism. Our intravenous studies yielded images of diagnostic quality in 98% of cases. Compared to conventional pulmonary angiography, intravenous digital subtraction angiography (IV DSA) is safer, faster, and easier to perform. This technique is an acceptable substitute for routine pulmonary angiography in all patients with pulmonary embolism. Intravenous DSA is currently the procedure of choice for the evaluation of patients with suspected pulmonary embolism.

For the angiographic diagnosis of pulmonary embolism (PE) we performed balloon-occlusion pulmonary cineangiography in ten consecutive patients. The technical aspects of the balloon-occlusion cineangiographic technique are reviewed, and its complementary role in the diagnosis of PE are outlined and illustrated with several examples.

Indications for hemodynamic monitoring include the need to assess left ventricular function, to estimate patient prognosis, to monitor cardiac performance, to study the cardiac response to drugs, to evaluate new methods of treatment, and to diagnose and treat cardiac dysrhythmias. Diagnoses which may be made or clinically facilitated include cardiogenic shock, hypovolemic shock, right ventricular infarction, ruptured ventricular septum, mitral regurgitation, low cardiac output syndrome, cardiac tamponade, and pulmonary embolism. Potential complications of hemodynamic monitoring include dysrhythmias, balloon rupture, knotting of the catheter, pulmonary infarction, pulmonary artery rupture, infection, and deep vein thrombosis.

An experiment was designed to determine whether or not acute pneumococcal pneumonia in dogs is associated with intravascular thrombosis, or with angiographic features distinguishable from pulmonary embolism. In dogs with normal baseline chest radiographs and perfusion scans, pneumonia was produced by transbronchial instillation of type III pneumococcus. After 2 days, perfusion scans demonstrated discrete appropriate defects. In vivo magnification pulmonary arteriography, postmortem pulmonary arteriography, and histologic examination disclosed no evidence of thrombi.

This clinical report deals with a femoral venous aneurysm as a source of recurrent pulmonary embolism. The literature concerning venous aneurysms is reviewed with emphasis on those cases which were complicated by venous thrombosis and pulmonary embolism. This case demonstrates that lower leg venous aneurysms can occur in either sex and in different age groups. Venography was shown to be important in diagnosing these lesions. Surgical resection may be necessary to prevent potential thrombosis and life-threatening pulmonary embolism.

Iliofemoral venous thrombosis may result in pulmonary embolism or a post-thrombotic syndrome. The incidence of pulmonary embolism after nonsurgical treatment is 10%, that of post-thrombotic syndrome 60%. The use of fibrinolysis is limited because of numerous contraindications. One hundred and sixty five iliofemoral venous thrombectomies were performed between 1976 and 1981. The patients ranged in age from 17 to 88 years (mean age 56). The postoperative mortality was 2.4%. One hundred and thirty four out of 165 patients were re-examined and 69 underwent phlebography. Over 70% were completely well. A post-thrombotic syndrome was present in four cases. The patency rate, phlebographically determined, was 60% at the popliteo-crural and iliofemoral level. In 32.5% a recanalized femoral vein with patent iliac vein was shown. Only in 5 cases a permanent occlusion of the iliofemoral vein was observed. Immediate thrombectomy in acute iliofemoral venous thrombosis has given excellent results. The incidence of pulmonary embolism and post-thrombotic syndrome was considerably reduced and good functional results were achieved.

120 high risk patients who underwent prophylactic inferior vena cava clipping were retrospectively evaluated to determine the incidence of post clipping leg swelling and pulmonary embolism. Each one of those patients had at least two criteria for the clipping. These criteria of high risk factors were precisely identified. There were two patients who had postoperative pulmonary embolism but none of them was fatal, i.e. less than two per cent. Two patients developed severe leg swelling (less than two per cent) and six had mild leg swelling (less than six per cent). Prophylactic inferior vena cava clipping is a safe and effective mean to prevent post-operative pulmonary embolism.

A series of 400 consecutive patients subjected to reconstructive arterial surgery were randomly allocated into four equal groups in order to study the effect of dipyridamole and acetylsalicylic acid (ASA) in the prevention of deep venous thrombosis and pulmonary embolism. There were 11 drop-outs. In the dipyridamole-ASA group there were no thrombotic complications while in the control group without antithrombotic therapy five cases of deep venous thrombosis and two cases of fatal pulmonary embolism were encountered (p < 0.05). In the groups receiving either dipyridamole or ASA alone two and four cases of deep venous thrombosis, respectively, were found. It is concluded that treatment with dipyridamole and ASA combined is useful in preventing postoperative thrombotic complication after peripheral vascular reconstructive surgery.

When anticoagulant treatment of pulmonary embolism is contraindicated or fails, interruption of blood flow through the inferior vena cava offers an alternative method for preventing further embolic episodes. In the past this required abdominal surgery, but currently several clot-capturing devices have been designed for insertion into the human inferior vena cava indirectly via a jugular or femoral venotomy. Another device is being developed for percutaneous delivery through a standard angiographic catheter. In addition to variations in the delivery methods, the form, mechanical effectiveness, and complications of these differ markedly. A suction-cup device is also available for the transvenous removal of pulmonary emboli.

The purpose of this study was to characterize the long-term safety and efficacy of the stainless-steel Greenfield filter. All patients who underwent Greenfield filter placement at three institutions during tenure of the senior author (L.J.G.) were entered prospectively into a filter registry and followed on an annual basis. Follow-up consisted of clinical examination to evaluate the status of venous disease or recurrence of pulmonary embolism, abdominal radiographs to determine the stability of the filter and an evaluation of the patency of the inferior vena cava and lower extremities. This report summarizes the 20-year experience. The rate of recurrent pulmonary embolism was 4% and the caval patency rate was 96%. Some filter movement of no clinical significance was seen in 8% of cases. There was no procedural mortality and morbidity was minimal. Greenfield filter insertion provides long-term protection from pulmonary embolism while preserving caval patency.
