1/583. Azygos continuation syndrome with aneurysm of the azygos vein: CT and MR appearances.

    We present a case of azygos vein continuation with aneurysm of the azygos vein simulating a tumor in the right upper mediastinum. The dynamic CT examination initially showed a structure of malignant appearance during the early arterial phase. Further dynamic CT revealed marked enhancement of the mass during the late venous phase, suggesting a vascular structure. Confirmation of diagnosis was made by MRI using a fast gradient echo imaging technique in cine mode, showing turbulent flow in the azygos aneurysm, and contrast-enhanced MR angiography, demonstrating a dilated azygos vein. Dynamic CT has a potential pitfall in the diagnosis of vascular structures.

2/583. Primary venous aneurysms--case reports.

    Venous aneurysms are rare lesions that may be the source of pulmonary emboli and can result in death. The authors have recently treated several patients who had venous aneurysms of the upper extremity, lower extremity, and jugular system. Venous aneurysms usually appear to have a safe natural history in these locations, although all of the reported patients required surgery after the development of symptoms owing to complaints of pain, and/or cosmetic appearance, and/or a diagnosis of thrombosis. These cases are presented, along with a review of venous aneurysms occurring at other sites and their causes.

3/583. Atherosclerotic aneurysms of the superficial femoral artery: report of two ruptured cases and review of the literature.

    Isolated arteriosclerotic aneurysms of the superficial femoral artery are rare. In citing the literature a total of 30 cases in 28 patients in the last 25 years were found. In addition to the above cases, two aged patients with ruptured aneurysms of the superficial femoral artery are reported; these were managed successfully with partial aneurysmectomy and restoration of the circulation of the extremity with a synthetic graft. The prognosis for this type of aneurysm following surgical therapy is good, despite the advanced age of the patients, and amputation is relatively rare, occurring in only two out of the 30 aneurysms (6.6%) reported. The risk of rupture is 46.6% (14/30) and is greater than that found in peripheral aneurysms. This, in association with the possibility of the creation of thrombosis (5/30; 16.6%) or embolization (1/30; 3.3%), threatens the extremity itself as well as the life of the patient, increasing the risk of complications and even death at a rate of 66.6% (20/30). Timely diagnosis, immediate surgical reconstruction and prompt mobilization, however, can guarantee a good prognosis for these aged patients.

4/583. splenic vein aneurysm: is it a surgical indication?

    splenic vein aneurysms are rare and are usually caused by portal hypertension. Symptoms are unusual, but may include rupture or abdominal pain. diagnosis can usually be made either by means of duplex ultrasonography or computed tomography scanning. Treatment varies from noninvasive follow-up to aneurysm excision. We report an expanding splenic vein aneurysm in a young woman with abdominal and back pain and no history of portal hypertension. She was treated with aneurysm excision and splenectomy.

5/583. Bilateral fibromuscular hyperplasia in the internal carotid arteries with aneurysm formation.

    A patient with bilateral fibromuscular hyperplasia in the carotid arteries with development of aneurysms is reported. The patient had no symptoms except for a palpable mass on one side and a bruit on both sides. Surgery was carried out bilaterally, using direct end-to-end suture on one side and a reconstruction with an autologous vein on the other side. It is suggested that fibromuscular hyperplasia may be the cause of some of the internal carotid artery aneurysms reported as congenital or with uncertain etiology. Reconstructive surgery of the carotid artery is recommended due to the obvious hazards of the condition.

6/583. Anterior jugular venous aneurysm.

    An anterior jugular venous aneurysm in a 4-year-old boy is described. Noninvasive radiology confirmed the diagnosis and excluded any deeper cervical venous malformation. Surgical excision was uncomplicated. Whilst the internal jugular vein is the commonest site of a venous aneurysm, recognition that the anterior jugular vein can be affected in isolation may help to avoid diagnostic confusion. A unifying concept of pathogenesis is suggested.

7/583. aneurysm of saphenous vein coronary bypass graft: diagnosis by computed tomography.

    A patient with a history of coronary artery bypass graft surgery underwent computed tomography scanning for evaluation of a lung mass. A heterogeneous mediastinal mass discovered incidentally on computed tomography scanning was shown to be a saphenous vein bypass graft aneurysm.

8/583. Late development of an aneurysm of a saphenous vein used as an aortocoronary conduit.

    A case of a large saphenous vein aortocoronary aneurysm that developed late after coronary artery bypass grafting is presented. This is the first case of a large saphenous vein aortocoronary aneurysm identified by serial angiography and 3-dimensional computed tomographic scanning.

9/583. aneurysm of the small saphenous vein presenting as a popliteal mass: a case report.

    This report describes an aneurysm in the superficial small saphenous vein in a 44-year-old woman who presented with a popliteal mass. A venous aneurysm in this area is rare but should be among the differential diagnoses for a popliteal mass for optimal treatment and outcome.

10/583. An aneurysm involving the axillary artery and its branch vessels in a major league baseball pitcher. A case report and review of the literature.

    baseball pitchers appear to be prone to aneurysms of the axillary artery and its branches. The cause is probably related to repetitive compression of or tension on the vessels at the level of the pectoralis minor muscle and the humeral head, which is exacerbated by the pitching motion. The incidence of aneurysms of the axillary artery and its branches among pitchers and other athletes is not known, nor is it clear whether pitchers who are at high risk of vascular injury can be identified before irreversible damage to the vessels has occurred. Perhaps patients who have documented compression or occlusion of the vessel with the arm in the abducted, externally rotated position are at higher risk. Screening pitchers to identify those with axillary artery compression, aneurysm, or thrombosis has also not been shown to be effective. Certainly, many pitchers will have some level of compression of the axillary artery with their arm in the pitching position but will never develop any clinical abnormality requiring treatment. Screening would therefore probably lead to a high false-positive rate. It is clear, however, that pitchers who complain of ischemia-type symptoms such as early fatigue or who have evidence of emboli require a complete evaluation to rule out any abnormality of the axillary artery or one of its branches. Orthopaedic surgeons who see pitchers and other athletes involved in repetitive overhead motions need to be aware of this disorder so that they order the appropriate tests and obtain a vascular consultation--and make a prompt diagnosis. Treatment will vary depending on the type of lesion and on which vessel or vessels are involved, and should be decided on by the team of surgeons treating the patient.
