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 ...

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 ...
Galbraith K - - 1985
A 5 1/2-year experience of 147 patients with arterial embolism of the limbs is reported. The mean age was 66.9 years, range 24-90 years and the male to female ratio was 1.07 to 1. Two distinct types of embolic episode with very different clinical consequences were recognised. Type I (64%) ...

Recurrent pulmonary emboli ultimately may produce respiratory insufficiency, severe hypoxemia, and progressive pulmonary hypertension. In many patients this syndrome is silent in its initial phases, and when thrombophlebitis is present it is often unresponsive to anticoagulant therapy. Unless pulmonary embolectomy is undertaken, most of these patients characteristically succumb with severe ...
Baker P B - - 1985
We examined a case of primary pulmonary artery sarcoma and reviewed 45 cases that we found previously reported in the English literature, with particular attention given to the pathologic features. These sarcomas involve the pulmonary arterial trunk, left and right main pulmonary arteries, pulmonary valve, and right ventricular outflow tract. ...
Harris W H - - 1984
15-O-labeled carbon dioxide (C15O2) was used for the detection of preoperative and postoperative pulmonary emboli in seventy-three patients, more than forty years old, who had undergone a total hip replacement. When the C15O2 scan was suggestive of pulmonary embolism, it was followed by conventional perfusion and ventilation (V/Q) scans. If ...
Willett I R - - 1984
A case of primary liver cell carcinoma is presented in which tumor emboli to the pulmonary microvasculature resulted in pulmonary hypertension, documented by clinical, radiologic, electrocardiographic, and cardiac catheter studies. Emboli arose from tumor invading the portal vein and passed via a patent splenorenal shunt to the systemic venous and ...
Busch U - - 1984
A 69-year old woman was admitted because of recurrent syncopal episodes. In hospital, she had repeated attacks of near fainting or syncope when she was turned into the left decubitus position. Continuous arterial pressure monitoring revealed that severe hypotension initiated these events. Secondarily, the heart rate dropped markedly. The symptoms ...
McCready R A - - 1984
We have presented a case of SMA embolization with early diagnosis and successful embolectomy. A high index of suspicion is necessary, since the relative paucity of early signs and symptoms often belies the gravity of the situation. Prompt angiography can corroborate the diagnosis and allow expeditious laparotomy. Although some authors ...
Robicsek F - - 1984
A method is presented that uses a double-lumen balloon catheter to perform embolectomy under contrast-enhanced fluoroscopy control. The technique has the advantage of localization of the thrombi before removal; it permits the individual arterial branches to be entered during embolectomy and allows confirmation of the patency of the arterial tree ...
Giordano J M - - 1984
Fluoroscopy with the C arm allows for the immediate assessment of distal arterial circulation following embolectomy. With the use of two embolectomy catheters, each one of the trifurcation vessels can be separately cannulated to remove additional thrombus. The technique described is not difficult and adds little time to the operative ...
Goldman R L - - 1984
Foreign body pulmonary emboli from a cranial venous sinus are unusual. Two patients are presented with gunshot wounds to the head who subsequently developed foreign body pulmonary emboli. Neither had any pulmonary complaints at presentation or during followup. Radiologists and primary care physicians should be aware of the possibility of ...
Sniderman K W - - 1984
Distal embolization occurred in 14 of 339 (4%) attempted percutaneous transluminal angioplasty (PTA) procedures, including five of 225 stenoses (2.2%) and nine of the 81 occlusions (11%) that were crossed successfully in 114 attempts (8%). Transcatheter embolectomy by aspiration through a nontapered large-bore catheter was technically successful in five of ...
Ferris E J - - 1984
The value of digital pulmonary arteriography and balloon-occlusion cineangiography was investigated in 118 selected patients. In one series of 40 patients, digital pulmonary arteriography correctly identified pulmonary emboli in 20 (75%) of 26 positive examinations when interpretation was confined to the first three divisions of the pulmonary artery. In a ...
Hasegawa H - - 1984
The incidence of pulmonary thromboembolism in the total autopsied cases and the actual reported cases of pulmonary thromboembolism in Japan has gradually increased. Since there is no part of the history, physical examination or noninvasive laboratory findings that is specific, a tentative criteria for diagnosis of pulmonary thromboembolism is proposed ...
Weiner M A - - 1984
Two cases of spontaneous lysis of arterial thrombi are described. The occurrence of spontaneous thrombolysis and the relative ease of performing Fogarty embolectomy (thrombectomy) in peripheral arteries should be considered along with the clinical status of a patient who is viewed as a possible candidate for thrombolytic therapy, a procedure ...
Duroux P - - 1984
Many therapeutic aspects of venous thromboembolism continue to generate controversy so that the general therapeutic guidelines given below are only indicative. The first step is the diagnosis of venous thromboembolism; this is done in the vast majority of patients by visualization of blood clots using either pulmonary angiography or phlebography. ...
Hayes S P - - 1983
The diagnosis of pulmonary emboli may be difficult or delayed because of the clinical similarity to other acute medical events or from superimposed embolic phenomena in patients with pre-existing pulmonary and cardiovascular disease. The clinical presentation, diagnosis, and medical and surgical intervention in patients with massive emboli are discussed.
Moreno-Cabral R J - - 1983
Pulmonary embolectomy under cardiopulmonary bypass was performed on a six-day-old infant. The clinical presentation suggested cyanotic congenital heart disease secondary to pulmonary stenosis or atresia with intact ventricular septum. At operation, a large blood clot was found completely occluding a normal pulmonary valve. The use of prostaglandin E1 facilitated cardiac ...
Needleman S W - - 1983
The prompt and accurate recognition of non-malignant complications is of critical importance in the care of cancer patients. Pulmonary thromboembolism is particularly important because it is common, treatable and frequently difficult to diagnose. Two patients are presented who died of recurrent pulmonary thromboemboli which were unrecognized because open lung biopsies ...
Keith J C JC - - 1983
The effects that 4 weeks of treatment of dirofilaria-infected dogs with either aspirin or prednisolone had on the pulmonary thromboembolism which occurs after they are given thiacetarsamide were determined, using light and electron microscopies. Pulmonary lesions in control dogs at 4 weeks after thiacetarsamide was given were compared with lesions ...
Barberena J - - 1983
Eleven patients were treated for acute pulmonary thromboembolism by perfusion of urokinase in the main pulmonary artery for a period of 12 hr with angiographic control. Clinical and radiologic improvement was achieved in all patients except for one in whom an embolectomy was later performed. The complications were similar to ...
Tessaro S V - - 1983
Acute posterior paralysis in two weaner pigs was attributed to ischemic infarction of the lumbar spinal cord due to fibrocartilaginous emboli. These arterial and venous emboli were assumed to have originated from the nucleus pulposus of one or more intervertebral discs. There was no indication of an initiating factor in ...
Wirsing P - - 1983
Between 1970 and 1981 a total of 79 surgical interventions were performed for acute ischemia of the upper extremities. The cause of occlusion in 70 patients was an arterial embolism, mainly affecting the brachial or radial artery. Embolectomy was successful in restoring the patency of the occluded vessel, regardless of ...
Klitenick M - - 1982
Pulmonary vein to artery missile embolus is extremely rare. Only one other case could be found in the world's literature and the present case appears to be the only reported survivor. The key in the safe management of missile embolus is in the prompt and proper care of the primary ...
Levin B H - - 1982
Eight instances of delayed or late embolectomy are presented with a review of 241 additional patients from the literature. The time interval from clinical onset to embolectomy ranged from three days to eight weeks in our series and two days to seven weeks in the additional 12 series surveyed. One ...
Guyer R D - - 1982
Because of the controversy surrounding prophylaxis for thromboembolism after total hip surgery, we undertook a prospective study comparing the results of the administration of aspirin with that of low doses of warfarin in 194 patients (200 hips) undergoing total hip replacement. The incidences of both clinically apparent and silent (asymptomatic) ...
Mattox K L - - 1982
During the period from 1961 to 1981, 40 pulmonary embolectomies were performed in 39 patients who were in extremis at the time of initiation of cardiopulmonary bypass. In a 460-bed hospital with more than 17,000 acute admissions and 4,000 operations per year, this small number represents the few patients who ...
Haimovici H - - 1982
Arterial embolism of the upper extremity is not as rare and especially not as benign in all instances as was considered in the past. Postembolic ischemic changes or frank gangrene of fingers or hand may occur in a substantial percentage of patients. This paper will attempt to update the current ...
Tsao M S - - 1982
Pulmonary embolism discovered at autopsy is still as prevalent as previously reported in the last three to four decades. Only a certain percentage of pulmonary emboli result in pulmonary infarction. Recently published studies have suggested that importance of the size of the occluded pulmonary artery in the occurrence of infarction. ...
Arvan S - - 1982
The transit of peripheral emboli on two-dimensional echocardiography through the right side of the heart has not been reported before, to the best of our knowledge. Although this finding was fortuitous and unexpected in view of the transient and unpredictable nature of systemic venous emboli, it was a clinically important ...
Huberman R P - - 1982
Cardiopulmonary dysfunction has been observed after the removal of benign hydatidiform mole. Of 60 cases reviewed with benign trophoblastic disease, five developed respiratory complications. Two patients developed pulmonary edema that progressed to adult respiratory distress syndrome. Autopsy of two patients showed no evidence of pulmonary trophoblastic emboli. Possible etiologies for ...
Graham J M - - 1981
Victims of gunshot wounds may be noted to have bullets overlying the cardiac silhouette on roentgenogram. Direct cardiac penetration, bullet embolus to the heart, and missile proximity to the heart are all possibilities which must be differentiated. An unusual case of bullet embolism is presented in which thoracotomy was initially ...
Akyön M G - - 1981
During resection of a Wilms' tumour in a 10-year-old girl, sudden bradycardia, hypotension and cyanosis developed, leading to cardiac arrest. It was thought that part of the tumour had caused a pulmonary embolus. After prompt resuscitation, cardiopulmonary bypass surgery was started within 20 min. At operation the left pulmonary artery ...
Dor V - - 1981
Delayed unilateral pulmonary embolectomy via the peripheral approach has been performed in 12 patients suffering from chronic pulmonary vascular obstruction after a single or repeated embolisms. Arterial hypoxemia and pulmonary hypertension were present in all cases. Embolectomy was performed several months or years after the initial event. There were 2 ...
Clarke D B - - 1981
Forty-two patients who had sustained massive pulmonary embolism were treated by emergency pulmonary embolectomy using normothermic venous inflow occlusion circulatory arrest. Of 26 patients who had not had cardiac arrest before surgery 25 survived the operation, but 7 later died from various causes. Only 1 of 16 patients who had ...
Mills S R - - 1980
In some patients acute pulmonary emboli may fail to resolve normally, resulting in chronic pulmonary embolism. This may lead to pulmonary hypertension, respiratory insufficiency, cor pulmonale, and death. The angiographic evaluation in nine patients with chronic pulmonary embolism who underwent embolectomy is presented. Particular emphasis on the predictive value of ...
Chan C W - - 1980
In 3,876 autopsies performed between 1964 and 1974 in adult Hong Kong Chinese, the incidence of pulmonary thromboembolism was 0.75%. In a prospective study of 70 autopsies, the right lungs were inflated, fixed, slab-sectioned, and studied for pulmonary thromboembolism. Twenty-seven per cent had evidence of pulmonary thromboembolism, although in only ...
Nichols A B - - 1980
A new radionuclide approach to the scintigraphic detection of pulmonary emboli is described. This method utilizes cyclotron-produced C15O2, administered by inhalation, for rapid labeling of pulmonary blood. Following clearance of oxygen-15 from the lungs by pulmonary blood flow, focal retention of activity results from stasis of blood distal to emboli. ...
Giudice J C - - 1980
Although low-dose heparin therapy is the technique most commonly used for prophylaxis of pulmonary thromboembolism, its usefulness is being questioned. Platelet deaggregation prophylaxis with either aspirin or dipyridamole, or both, apparently is a reasonable alternative, but further studies are needed. For treatment of pulmonary thromboembolism, continuous conventional-dose heparin therapy is ...
Ettien J T - - 1980
Of all upper extremity emboli, 20 per cent arise from an arterial, not cardiac, source. Therefore, one should always consider an arterial source for embolic occlusion of the axillobrachial axis. Chronic axillary crutch use in the patient with acute, noncardiac embolism of the upper extremity should suggest the diagnosis of ...
Wilson K H - - 1980
A patient who fell on his right leg from a scaffold presented with fever of unknown etiology. Complete workup to rule out infectious causes for his fever was nonrevealing. Because of a history of transient episodes of dyspnea, lung scan was performed which was compatible with pulmonary emboli. Response to ...
Levin D C - - 1980
A major potential hazard of therapeutic occlusion of arteries by selectively injected Gelfoam pledgets is inadvertent reflux of nonopaque emboli into the aorta with resultant occlusion of other vessels. A simple method of injecting Gelfoam emboli through the standard nonoccluding arterial catheters customarily used for diagnostic arteriography was experimentally tested. ...
Moser K M - - 1980
A flexible, fiberoptic device, fitted with an inflatable distal balloon, has been used to directly visualize the great veins, right cardiac chambers, pulmonary arteries, and experimental emboli in vivo in the dog. Insertion and manipulation of the device have been well-tolerated. The angioscope has significant potential for investigative and clinical ...
Laha R K - - 1980
The canine middle cerebral artery (MCA) was embolized with a pliable cylinder 8 mm long by 1.6 mm in diameter via the internal carotid artery. Both control and experimental embolectomies were performed 6 hours following embolization. The experimental animals were treated with low molecular weight dextran (LMD). In the control ...
Brismar B - - 1980
In 14 patients with the respiratory distress syndrome it was demonstrated that this condition was caused by the administration of excessive volumes of fluid. In none of six patients examined post-mortem were any signs of thrombi or emboli observed in pulmonary vessels. Caution with the initial supply of fluids following ...
Murray H W - - 1979
Fever patterns associated with pulmonary thromboembolism have not been well characterized. Upon review of 35 consecutive patients with angiographically documented pulmonary emboli, fever was present in 24 patients; and in 20, it was attributed solely to pulmonary thromboembolism. Analysis of these cases indicates that high fever (temperature greater than 39 ...
Henrichs K J - - 1979
A 25-year-old man with chest pain and shortness of breath was found to have a primary sarcoma of the pumonary artery. On light- and electronmicroscopy and immunofluorescence microscopy the lesion was found to be composed of cells of smooth muscle origin. It was diagnosed as leiomyosarcoma. The cross and microscopic ...
