1/349. 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.

2/349. 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.

3/349. Celiomesenteric anomaly with concurrent aneurysm.

    We describe a rare case of a celiomesenteric anomaly with concurrent aneurysm. The patient, a 53-year-old man, had no abdominal pain or discomfort. The presence of a celiac artery aneurysm was suspected on the basis of the results of abdominal computerized tomographic scanning and echo ultrasound scanning performed because of proteinuria. Intra-arterial digital subtraction angiographic results showed the anomaly and aneurysm. Because of the risk of rupture of the aneurysm, the lesion was repaired surgically, with the placement of an interpositional prosthetic graft. We found no previous reports of celiomesenteric anomaly with concurrent aneurysm repaired with prosthetic graft.

4/349. 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.

5/349. Idiopathic azygos vein aneurysm: a rare cause of mediastinal mass.

    Venous aneurysm of the azygos arch is a very rare cause of mediastinal mass and is usually an incidental finding on chest radiography. Nowadays the diagnosis is made by non-invasive tests such as thoracic CT scanning and/or magnetic resonance imaging. The case is described of an asymptomatic woman in whom a mediastinal mass due to an azygos vein aneurysm was diagnosed by non-invasive procedures, the aetiology of which, in all probability, was idiopathic.

6/349. Idiopathic dilatation of the pulmonary artery: report of four cases.

    Idiopathic dilatation of the pulmonary artery (IDPA) is a rare congenital disease which is usually detected fortuitously on chest x-ray, thus radiologists must be aware of this clinical entity. This report describes four cases to which magnetic resonance imaging (MRI) played a major role in diagnosing IDPA and in detecting the concomitant findings observed in this disease. MRI is a non-invasive procedure with many advantages for the accurate and reproducible measurement of artery structures, which makes it the preferred option for combined use with echocardiography in the diagnosis and follow-up of patients with IDPA.

7/349. Aneurysms and hypermobility in a 45-year-old woman.

    EDS type IV presents a diagnostic and therapeutic challenge to the primary care physician, surgeon, and rheumatologist. In patients for whom the diagnosis is known, avoidance of trauma, contact sports, or strenuous activities, joint bracing and protection, and counseling on contraception are helpful preventive strategies. In patients presenting with vascular, gastrointestinal, or obstetric complications, a history of hypermobility and skin fragility (easy bruising, abnormal scarring, poor wound healing) should lead to a suspicion of this diagnosis, and to caution in the use of certain invasive diagnostic and operative techniques. Efforts should be made to examine family members. Most importantly, when caring for such patients, the acute onset of headaches, chest pain, shortness of breath, and abdominal pain should arouse suspicion of a potentially catastrophic vascular or visceral event.

8/349. The use of an external-internal shunt in the treatment of extracranial internal carotid artery saccular aneurysms: technical case report.

    BACKGROUND: Extracranial internal carotid artery aneurysms (EICAA) are rare lesions. Resection and grafting is the preferred method of management. However, the details of shunt use in surgery for this type of aneurysm has been described in few articles. We describe an external-internal shunt with intra-aneurysmal trans-orifice insertion. CASE REPORT: A 55-year-old woman presented with a 5-year history of a progressively enlarging pulsatile neck mass. An examination revealed no neurological deficit. Right carotid angiogram showed a saccular EICAA involving the ICA distal to the bifurcation, with kinking of the internal carotid artery (ICA). The dome of the EICAA extended from the upper border of C4 to the midportion of C2 and the maximum diameter was 4 cm. RESULTS: Using the shunt technique, we successfully removed the aneurysm and reconstructed the ICA. The end-to-end anastomosis was easy because the shunt was involved only in the distal free end of the ICA, but not in the proximal free end of the ICA. CONCLUSION: This technique could be an option for the treatment of EICCA when a shunt is needed to maintain the cerebral circulation.

9/349. Isolated true atherosclerotic aneurysm of the profunda femoris artery. Case report.

    The authors report a case of true isolated atherosclerotic aneurysm of the profunda femoris artery. On the basis of a careful search of the literature some aspects of this rare disease are illuminated in terms of its low incidence, pathologic background and treatment; the last should always be aggressive due to the high possibility (about 50%) of major complications mainly represented by rupture. Simple aneurysmectomy without flow re-establishment may be allowed only if the femoropopliteal tract is normal

10/349. Successful transcatheter embolization of a pancreaticoduodenal artery aneurysm in association with celiac axis occlusion: a case report.

    We report a case of a pancreaticoduodenal artery (PDA) aneurysm in association with celiac axis occlusion. A 54 year-old female complaining of abrupt onset of abdominal pain was admitted to our hospital. On admission, abdominal CT examination revealed a hematoma in the retroperitoneal space. Selective superior mesenteric artery (SMA) angiography disclosed an aneurysm in the anterior inferior pancreaticoduodenal artery (AIPDA). The celiac axis was occluded and blood was flowing to the liver and spleen via the enlarged pancreaticoduodenal arcade from the SMA. Transcatheter embolization of the aneurysm was performed successfully. Up to 1996, there have been 37 reported cases of PDA aneurysm in association with celiac axis stenosis or occlusion, including this one. Transcatheter embolization was performed successfully in only 5 of these cases. The formation of this type of PDA aneurysm is thought to be a result of the increased blood flow in the pancreaticoduodenal arcade due to celiac axis stenosis or occlusion. The transcatheter embolization performed in our report produced a far greater blood flow, which may lead to further aneurysmal formation. Careful follow-up is therefore necessary.
