Persistent ischaemia occasionally follows technically-successful arterial embolectomy, and has generally been ascribed to small-vessel thrombosis in the distal vascular bed. Because of the possibility that distal vasospasm might be a contributory cause, we conducted a prospective randomised trial of vasodilator therapy in this setting. In 50 consecutive patients presenting with ...
Masters R G - - 1988
Pulmonary embolism remains a frequent and often fatal disorder. For the majority of patients, anticoagulation with heparin followed by warfarin represents the primary mode of treatment. Thrombolytic therapy is recommended for the patient with massive pulmonary embolism that has produced hypotension. Embolectomy is reserved for the patient with post embolic ...

Plasma fibronectin, a glycoprotein that is a component of blood thrombi, was evaluated for the in vivo scintigraphic detection of pulmonary emboli in dogs. Fibronectin (canine or human) was labeled with either 131I or with 111In and diethylenetriaminepenta-acetic acid (DTPA) as the bifunctional chelating agent using a modification of the ...
Sleyster T J - - 1988
A rare case of malignant fibrous histiocytoma occurring in the pulmonary artery is reported. Such primary pulmonary artery sarcomas may have the diagnosis suggested by angiography or echocardiography; radiographically and in perfusion-ventilation scanning their usual unilateral origin (with later spread) and the persistence of the perfusion defect are among the ...
Chintapalli K - - 1988
Computed tomographic findings in 18 patients with pulmonary thromboembolism are retrospectively reviewed. In the majority of patients, thromboembolism was not suspected clinically. The CT findings can be divided into two groups: vascular and parenchymal changes. The most frequent vascular findings is an intraluminal filling defect or defects due to thrombus. ...
Schwarcz T H - - 1988
Arterial stenosis occurring after balloon catheter embolectomy may be caused by myointimal hyperplasia (MIH). This study investigated the effects of shear force and repeated catheter withdrawals on the development of MIH after embolectomy. The procedures were performed in the common carotid and common femoral arteries of 18 anesthetized dogs. During ...
Putnam J B JB - - 1988
A 5-year-old child experienced acute hemodynamic decompensation and hypoxia four weeks following an uneventful Fontan procedure for univentricular heart. Cardiac catheterization revealed complete occlusion of the left pulmonary artery, and emergent pulmonary artery embolectomy was performed. The source of the embolus was the atrial septal patch. Because of the altered ...
White G H - - 1988
Video angioscopy was employed in 12 patients to monitor thrombectomy or embolectomy within prosthetic bypass grafts (n = 4), saphenous vein grafts (n = 2), and native femoropopliteal arteries (n = 6). A flexible, 2.8 mm diameter angioscope was introduced into the vessel for confirmation and accurate localization of the ...
Fennerty A G - - 1988
The carbon monoxide transfer factor and its subdivisions, the pulmonary membrane diffusing capacity and the pulmonary capillary volume were measured in fourteen subjects following submassive pulmonary emboli, as demonstrated by a ventilation-perfusion scan, and in fourteen matched controls. Transfer factor and alveolar volume were significantly lower in patients with pulmonary ...

The clinical and pathological features of primary pulmonary artery sarcoma in two children are reported. The first patient presented with right ventricular outflow obstruction and underwent successful surgical resection of his tumor. The second patient developed cardiac arrest following a relatively short period of symptoms of right heart failure and ...
Promisloff R A - - 1988
A patient is described in whom clinical presentation, V/Q scan, and pulmonary angiogram were consistent with pulmonary embolus. No improvement occurred despite therapy with heparin. When sent for surgical embolectomy, sarcoma of the pulmonary artery was diagnosed. This entity, though rare, should be considered in the differential diagnosis of pulmonary ...
Lee A W - - 1987
Reported here is a case of axillary artery aneurysm secondary to crutch trauma as a source of emboli to the upper extremity. This patient along with several reported in the literature was initially diagnosed and treated for brachial artery embolism. It is believed that awareness of this entity as a ...
McCance A J - - 1987
In a consecutive series of 150 patients with acute myocardial infarction the incidence of pulmonary embolism in 100 of 116 early survivors was determined by radionuclide lung scanning. No patient had a clinically apparent pulmonary embolus. No scan showed a definite segmental pulmonary embolus. Three scans showed a high probability ...
Lie J T - - 1987
Myocardium as emboli is a decidedly rare phenomenon. Only three such examples were identified among 8033 consecutive autopsies performed over a ten-year period, 1976 to 1985, an incidence of 0.037%. In two of these three cases, myocardial emboli occurred in the systemic (coronary) circulation. The source of emboli was attributed ...

We report the radiographic appearance of a patient with metallic mercury pulmonary emboli. The mercury emboli appear as metallic densities in both a branching pattern and as tiny spherules. The differential diagnosis includes aspirated mercury or barium and barium pulmonary emboli. The recognition of either intracardiac or intragastrointestinal mercury can ...
Isringhaus H - - 1987
A tumor embolism with occlusion of the left pulmonary artery was the first manifestation of a hypernephroma. After angiographic diagnosis, embolectomy was performed successfully using the heart-lung-machine. Four days later, nephrectomy followed. In the meantime, the patient has experienced a period of 3 years free of symptoms and metastases.
Van Damme H - - 1987
A patient is reported whose symptoms and clinical features were interpreted as pulmonary embolism. However, the ultimate diagnosis was malignant fibrous histiocytoma of the pulmonary artery, which was made evident at operation. Although extremely rare in the early medical literature, primary sarcoma of the pulmonary artery has been reported more ...
Dregelid E - - 1987
Although it has been demonstrated that embolectomy through an arteriotomy on the brachial artery in the antecubital fossa yields better results than a more proximal arteriotomy, many surgeons continue to expose the artery proximal to the elbow. In this study arteriograms from 11 patients were used to show that the ...
Poskitt K R - - 1987
Multiple pulmonary emboli are recognized to be the cause of progressive pulmonary failure. In these patients, the source of emboli may be difficult to detect, even by venography. The authors describe the use of autologous Indium 111-labeled platelets to locate the origin in a patient with progressing right heart failure.
Farfel Z - - 1987
2DE permits detection of thromboemboli transiently entrapped in the right heart chambers while en route to the pulmonary arteries. Review of the 49 cases recorded to date reveals that the supple elongated clot produces a 2DE picture--a mass of changing configuration and striking mobility--that is highly characteristic. Since emboli that ...
Candan I - - 1986
A patient with Behçet's disease who had pulmonary and cardiac involvement is described. The cardiac lesion was endocarditis in the right ventricle and a thrombus on this lesion which caused pulmonary emboli. The thrombus was excised completely and hemoptysis stopped. Pulmonary defects shown by pulmonary scintigraphy did not disappear with ...

Pulmonary Kaposi's sarcoma related to the acquired immune deficiency syndrome (AIDS) has not been well characterized. To define the clinical, radiographic, and pathologic features of this entity, 11 autopsy-proved cases of pulmonary Kaposi's sarcoma were reviewed. The most common clinical symptoms were dyspnea and cough, but hemoptysis and stridor were ...
Nakayama D K - - 1986
Peripheral arterial emboli that result from bacterial endocarditis may be silent or catastrophic. Cardiac surgical intervention may prevent embolism, but the guidelines for timing of intervention are unclear. An accepted approach is to intervene only if two episodes of peripheral embolism occur. Our recent experience suggests a more refined approach ...
McBride K - - 1986
To examine the accuracy of ventilation-perfusion (V/Q) scanning, we retrospectively reviewed pulmonary angiograms and V/Q scans from 150 patients clinically suspected of having pulmonary embolism. Pulmonary emboli were documented by angiography in 56 patients (37%). In seven patients V/Q scans were interpreted as being normal and these seven patients were ...
Purdy L J - - 1986
Nine open lung biopsies and nine transbronchial biopsies from 10 patients with pulmonary Kaposi's sarcoma were reviewed to define the pattern of involvement in the lung by Kaposi's sarcoma and to determine the usefulness of transbronchial biopsy in making the diagnosis. There were nine patients with acquired immune deficiency syndrome ...
Hart G K - - 1986
Venous thromboembolism to the heart is a rare and often fatal condition that is now being recognized more frequently owing to the widespread use of two-dimensional echocardiography. Death may be due to embolic obstruction of the tricuspid or the pulmonary valves, or to further migration of the embolus to the ...
Harris R W - - 1986
A case of acute aortic occlusion caused by embolization of malignant melanoma tumor fragments is presented. Transfemoral catheter embolectomy restored normal lower extremity circulation. Noncardiac tumor emboli, although rare, originate either from primary pulmonary malignancies or nonpulmonary malignancies with pulmonary metastases and pulmonary vein invasion. Tumor embolization should be considered ...
Tilsner V - - 1986
Fibrinolytic therapy of pulmonary emboli is indicated in persistent pulmonary hypertension or acute shock. If possible, diagnosis should be confirmed by pulmonary angiography - in our hands digital subtraction angiography has proved of value. Emboli of such size that spontaneous lysis is unlikely can be actively removed by lysis therapy ...
Sevitt S - - 1986
Seventy-five intimal arterial thickenings (from 58 subjects) related to pulmonary emboli were examined. Many showed residua derived from the emboli (fibrin, platelets, haemosiderin) and proliferation of elastica and smooth muscle cells. Features resembling those of atherosclerosis were the frequent presence of extracellular lipid and apolipoprotein-B containing lipoproteins (LpB) which corresponded ...
Goldberg M E - - 1986
Transvenous pulmonary catheter embolectomy is being used as a method of treatment for patients suffering from massive pulmonary embolism. The anaesthetic management of these patients can be complex. Presented is a case of transvenous pulmonary embolectomy in a patient who also had an intravascular volume deficit secondary to haemorrhage and ...
Moeser P - - 1986
Malignant peripheral arterial emboli are extremely unusual. Most reported cases of malignant arterial emboli are secondary to invasion of the systemic circulation by pulmonary malignancies via the pulmonary veins. We report a rare case of a primary sarcoma of the aortic arch that presented as malignant emboli. When confronted by ...
Meyerovitz M F - - 1985
Biplane pulmonary cineangiograms utilizing a short cine pulse width and automatic brightness control were performed in 47 patients during normal respiration. The diagnostic quality of the arteriograms was categorized as good in 33 patients, fair in 12 patients, and poor in two patients. Of the 18 patients in whom pulmonary ...
Shure D - - 1985
We evaluated the role of fiberoptic angioscopy in eight patients with suspected chronic pulmonary embolic obstruction of the pulmonary arteries. Angioscopy, preceded by ventilation-perfusion lung scans, right-heart catheterization, and pulmonary angiography, resulted in diagnostic changes in four patients: from pulmonary artery agenesis to chronic emboli; from chronic emboli to normal ...
Klinke W P - - 1985
We present a rare case of pulmonary trunk sarcoma in a young male in which the diagnosis was made antemortem. Total surgical removal of the tumor, including replacement of the pulmonary valve, was undertaken. This patient is the longest reported survivor of pulmonary trunk sarcoma and remains free of any ...
Bergman G - - 1985
Although the value of echocardiography in detecting left heart thrombus is well recognised, right atrial thromboembolism has rarely been identified in life. In two patients with pulmonary embolism of varying severity cross sectional echocardiography identified a thrombus moving freely within the right atrium and clearly showed its string-like or even ...
Balas P - - 1985
Although the earliest possible embolectomy is still correlated with best rates of limb salvage, we consider, as do most other authors, that the only critical criterion for operability must be the viability of the ischemic limb. Even in the presence of gangrene of the foot relief of arterial occlusion is ...
Panigrahi G - - 1985
Pulmonary angiography is considered the definite method of diagnosing pulmonary emboli. It is hypothesized that pulmonary cineangiography is superior to conventional pulmonary angiography for quantitation of pulmonary emboli. The present study was undertaken to test the hypothesis. Six patients with an age range from 27 to 70 years with documented ...
Del Campo C - - 1985
Massive pulmonary embolism continues to be a major cause of death in spite of improved medical therapy. Only a small number of patients with pulmonary embolism refractory to medical treatment are referred for pulmonary embolectomy. A literature review of patients with massive pulmonary embolism treated by pulmonary embolectomy showed that ...
