Sonography gives a characteristic picture of popliteal aneurysms, with an easily demonstrable connection of the sonolucent aneurysmal sac with the popliteal artery. It is a good screening procedure for suspected aneurysms and for patients with popliteal pain, mass, or sudden distal ischemia. Three case reports of five popliteal aneurysms diagnosed ...

An example of aneurysmal concentration of 99mTc-pyrophosphate (Tc-PPi) is described. An abdominal aortic aneurysm was suspected when a rectilinear bone scan showed an abnormal paraspinal area of activity. The aneurysm was confirmed by ultrasonic examination. Conventional radiographic examination failed to reveal calcification within the aneurysm. Aneurysmal concentration of Tc-PPi should ...

A routine chest X-ray taken four months after blunt chest trauma revealed a left ventricular aneurysm in a totally asymptomatic patient. At surgery a thin-walled, clot-filled aneurysm was successfully removed. This case demonstrates the need for careful follow-up of all patients sustaining blunt chest trauma even though the initial cardiac ...

Anterolateral myocardial infarction resulted in the formation of both true and false aneurysms in a 75 year old man in whom severe congestive heart failure subsequently developed as the false aneurysm became progressively larger. Left ventriculography detected and quantified both aneurysms, and demonstrated reasonable function of the remaining volume-overloaded left ...

Acute bacterial endocarditis developed in a 65-year-old man two years after surgical resection of a false aneurysm of the left ventricle. The patient had cerebral embolic manifestations, and coagulase-positive Staphylococcus aureus was cultured from each of six blood samples. A pericardial friction rub and a changing pansystolic murmur appeared during ...

Optimal projections for the delineation of anterior communicating aneurysms were investigated by means of model experiments and the results applied to 30 clinical cases. The oblique half-axial, the oblique orbital, the full axial, and the reverse oblique projections proved useful adjuncts to conventional projections in studying the anterior communicating aneurysm.

The development of a false aneurysm of the ascending aorta following arteriotomy and cannulation of the aorta performed during closure of a ventricular septal defect is described. The evidence suggest that the sutures of the arteriotomy led to rupture of the aortic wall and secondarily late formation of a false ...

During a 20 year period, 1,287 patients were submitted to arterial reconstruction for aneurysm and occlusion of the aorta and iliac arteries. Good results were obtained in 1,230 (95.6 percent). Of these, 83 (6.4 percent) returned for reoperation. Reoperation was performed also in 18 patients operated upon elsewhere. Thus this ...

Real-time cross-sectional echocardiographic studies of the left ventricle were performed in 31 consecutive patients with angiographically proven left ventricular aneurysms (group I). In each of these patients the presence and location of the aneurysm was visualized by the cross-sectional echocardiography. In four patients discrepancy in the extent of the aneurysm ...

"B" mode ultrasound scanning is useful in the diagnosis of popliteal arterial aneurysms. It offers advantages over physical examination and arteriography, since these aneurysms are sometimes difficult to palpate and may be partially filled with laminated clot. The technique is noninvasive and without known hazard in this location. "B" mode ...

A false aneurysm with typical history, clinical and radiographic findings, and histological picture is reported. The absence of enlargement since onset and the absence of bruit were atypical. The latter was probably due to the thick wall of the aneurysm. False aneurysm should be part of the differential diagnosis of ...

A false aneurysm developed from the external iliac artery within the pelvic cavity following total hip surgery when methylmethacrylate cement had been used to fix the cup. The aneurysm was probably caused by a cement spicule which had entered the pelvis and had come into contact with the external iliar ...

Unlike the true left ventricular aneurysm, false aneurysms have recently been shown to be subject to late rupture. Rarely diagnosed before surgery or autopsy, the false aneurysm has never been identified by noninvasive techniques. We report the first such noninvasive diagnosis employing radioisotope gated cardiac blood pool imaging. Due to ...

Forty patients with aneurysms of the femoral arteries were evaluated. Thirty had 34 false aneurysms and 23 were secondary to disruption of the suture line of a graft-to-artery anastomosis. All the false aneurysms were found in association with a synthetic material used as a bypass or arterial substitute. No direct ...

The diagnosis of left ventricular aneurysm on routine chest examination can be elusive. Six cases are presented which illustrate a radiographic sign not previously emphasized: a soft tissue border seen retrosternally or superiorly on lateral chest film produced by the wall of the aneurysm silhouetting against the midline cardiac shadow. ...

An unusual form of left ventricular aneurysm affecting young Negroes has recently been described at the aortic or mitral valve ring; constitutional factors have been postulated. A 4-year-old Negro boy was observed with a left ventricular submitral aneurysm, probably one of the largest and one of the most calcified to ...
