Mattox K L - - 1979
The estimated course of a penetrating missile provides some clues to planning intraoperative priorities and management. However, missiles which become intravascular emboli present diagnostic and therapeutic dilemmas. Twenty-eight patients have been seen with bullet emboli. Five patients had emboli to the lungs, two of which were removed. Two large bullets ...

Pseudomonas aeruginosa displays a curious propensity for invading blood vessels and causing vessel wall necrosis. This bacteremia-related "vasculitis" is often associated with hemorrhagic necrosis and infarction of surrounding organ parenchyma. With the exception of skin lesions, however, clinical manifestations of Ps. aeruginosa vasculitis seldom occur. In the patient we describe, ...

Embolectomy was carried out in eight patients with pulmonary emboli. Angiographic diagnosis was obtained in six, and in two cases pulmonary angiography could not be done because of the very critical condition of the patients. In the latter two, diagnosis was made based only on clinical findings. Two patients died ...
Neuhaus A - - 1978
The occurrence of pulmonary emboli in 617 patients admitted to a respiratory intensive care unit was studied. Pulmonary emboli were found in 18 (27 percent) of 66 autopsies. Half of these pulmonary emboli were not diagnosed before death, despite persistent aggressive attempts to document pulmonary emboli. In this subpopulation of ...

A sensitive method for localizing the resting place of catheter-injected therapeutic gelatin emboli is described. Surgical gelatin (Gelfoam) is labeled with 99mTc and each embolus observed on the persistence scope of a gamma camera after injection. This technique reduces the chance of obstructing blood vessels other than those intended. Two ...

Two patients with malignant arterial emboli, one from a renal cell carcinoma and the other from a squamous cell carcinoma of the trachea, are described. Both patients had typical radiographic features of emboli on angiography. The origin of such arterial emboli is most probably a chest metastasis involving a pulmonary ...
Beckmann C F - - 1977
In patients with cardiomegaly, a common cause of nonuniform pulmonary artery perfusion on pulmonary arteriograms is compression of the left lower lobe arteries by the enlarged heart, an effect which is accentuated by gravity in the supine position. This may impede flow in such a manner as to erroneously suggest ...
Shmookler B M - - 1977
Clinical and morphologic observations are described in two women with primary sarcoma of the pulmonary trunk, and observations in 35 previously described patients with primary sarcoma involving a major extrapulmonary pulmonary artery are summarized. The neoplasm produces symptoms by causing obstruction to right ventricular outflow or by dislodging tumor fragments ...
Hohbach C - - 1977
Primary sarcomas of the large vessels are rare. They are observed most commonly in the pulmonary artery. Up to now 28 cases of primary sarcoma of the pulmonary artery have been described in the literature. The clinical features of this disease which presents considerable diagnostic difficulties are dominated by signs ...

Prevention of arterial thromboembolism with acetylsalicylic acid (ASA) was studied in 148 patients with single Starr-Edwards aortic ball-valve prostheses. These patients are suitable for such a study because they have a high incidence of arterial emboli derived mainly from thrombi formed on the valves. They were given either 1 Gm. ...
Sabiston D C DC - - 1977
The clinical course of most patients with pulmonary embolism is one of gradual resolution with re-establishment of flow in the pulmonary arteries. In a small but definite group of patients, the emboli do not resolve and a state of chronic pulmonary embolism ensues. The primary thrombotic process in the systemic ...
Laughlin R A - - 1977
A 32-year-old morbidly obese woman had bilateral subclavian artery embolism. After embolectomy, a right heart catheterization showed a patent foramen ovale and a right-to-left shunt. Pulmonary angiography revealed multiple pulmonary emboli. Bilateral lower extremity venography demonstrated left ileofemoral thrombi as the probable source. The patient was successfully treated with an ...

A 49-year-old woman had a six-week history of increasing shortness of breath and fatigue. X-ray films and pulmonary scans showed multiple areas of emboli, especially in the right lung. Treatment with heparin was unsuccessful, and although a repeat scan showed only slight changes, the patient's condition deteriorated. Acute pulmonary edema ...
Palant A - - 1976
Two patients with pulmonary hydatid embolization are described and commented upon in the light of 43 similar published cases. The diagnosis was strongly suspected from the medical history and the chest x-ray films and supported by angiocardiography. The angiocardiographic features of this condition have not been described previously in detail. ...
Garvey J W - - 1976
A case of haemorrhagic pulmonary oedema after successful pulmonary embolectomy is presented. The relevant literature is reviewed. Thirteen cases are analysed as well as the four survivors. The aetiology appears to be ischaemic damage of the capillary bed. This had previously been called incomplete infarction by Castleman. The incidence is ...
Price D G - - 1976
The natural history diagnosis and immediate treatment of patients suffering from pulmonary embolism has been discussed. Anaesthetists should use their influence to bring about a high standard of prophylactic care against deep venous thrombosis and consequently of pulmonary embolism. They are likely to be involved in the resuscitation and treatment ...
Burr L H - - 1976
A 20-year-old man with a known history of thrombophlebitis experienced massive pulmonary embolism with hypoxia and shock. Embolectomy was performed with hyperbaric oxygenation for cardiopulmonary support. Ligation of the inferior vena cava was required postoperatively to prevent further embolism. Hyperbaric oxygenation is an effective method of cardiopulmonary support for pulmonary ...
Cooper J D - - 1976
A 19-year-old woman developed cardiorespiratory failure from multiple, peripheral pulmonary emboli apparently developing over the preceding 3 weeks. She was not considered to be an operative candidate. However, when 3 days of intravenous heparin infusion and 30 hours of membrane oxygenator support failed to improve the pulmonary pathology, pulmonary embolectomy ...

Clinical assessment of the adequacy of arterial embolectomy and reconstruction is often unsatisfactory and inadequate. Objective information on the state of the distal circulation can be readily obtained at the time of surgery by arteriography. Illustrative cases demonstrating the usefulness of control arteriography obtained during the surgical procedure are presented.
Stephenson L W - - 1976
Bullet embolization to the pulmonary artery is a rare event. The purpose of this study is to report our experience with 2 patients and to review the 15 patients reported in the literature, with special emphasis on a rather peculiar complication that has occurred in 4 of the 9 patients ...
Hirsch S A - - 1976
We are reporting a new complication of the use of methylmethacrylate, namely occlusion of the iliac artery with embolization. We believe that the occlusion is related to trauma to the intima by the heat of polymerization created by methylmethacrylate, with resultant thrombosis. In view of the initial failure of embolectomy ...
Patel H D - - 1976
We have reported on a patient with isolated metachronous renal artery emboli. The second embolus was treated successfully surgically 12 hours after the onset of symptoms. A review of the literature shows that emboli to the renal arteries occur more frequently than realized and that late embolectomy often is successful. ...

Percutaneous coronary arteriography has been associated with numerous reports of embolic complications. Efforts to minimize such complications have focused upon normal hemostatic functions and the possible preventative role of systemic heparin. In considering the source and prevention of catheter emboli it is useful to review the mechanisms by which particulate ...
Hodgkinson D J - - 1975
Upper limb embolus cannot be regarded as a benign condition, with invariable recovery due to copious collateral circulation. Gangrene of the upper limb may occur, as shown in the series of cases in this report. The overall mortality rate remains considerable, because of associated cardiac disease, recurrent embolism, or both. ...
Holm J - - 1975
The frequency of arterial embolism is high and seems to be increasing. The introduction of the Fogarty catheter for embolectomy has afforded a considerable simplification of the operative technique. Nevertheless the mortality and amputation rates are still substantially high. Early diagnosis and further improved technique for removal of the embolus ...

When a patient presents with wheezing, pulmonary embolism is not usually considered as a possible cause. However, undoubtedly bronchoconstriction can be caused by pulmonary emboli and occasionally wheezing may be so obvious as to suggest a diagnosis of bronchial asthma. Eleven cases are reported in which wheezing was attributable to ...
Wilson J E JE - - 1971
This study correlated levels of activated fibrinolysis with the presence, extent, and rate of resolution of angiographically documented pulmonary emboli. Pulmonary emboli demonstrable by angiography were associated with detectable fibrin split products in the serum of 24 of 25 patients. In the absence of increased fibrin split products, pulmonary emboli ...
