Giant anevrisms of the splenic artery about six cases.

Splenic artery aneurysms are rare. Giant aneurysms more than 2,5cm are extremely rare. The splenic artery is the third site after the aorta and iliac arteries, and the first location for aneurysmal lesion of the visceral arteries. The etiology of splenic artery aneurysms is not yet well established, however, fibromuscular dysplasia, non-cirrhotic portal hypertension and pregnancy seem to contribute to the emergence and evolution of arterial lesions. The majority of splenic artery aneurysms are asymptomatic. However, epigastric or left hypochondrial pain may occur. Doppler ultrasound, computed tomography angiography or magnetic resonance imaging are usually performed in the diagnostic workup. Treatment procedure, surgical or endovascular, depends on the aneurysmal site (proximal or distal) and the type of elective or urgent intervention. The present study reports six cases of splenic artery aneurysm, with a diameter greater than 50mm, treated successfully with surgery.

[Painful cervical mass revealing an aneurysm of the internal jugular vein]. / Masse cervicale douloureuse révélant un anévrysme de la veine jugulaire interne.

Internal jugular vein aneurysms or phlebectasia of the internal jugular vein are considered a benign pathology. They are more and more diagnosed with the evolution of imaging techniques : ultrasonography, angioscanner and MRI. Clinically they are often by chance, however accompanying clinical signs can be seen such as pain, hoarseness or vocal cord paralysis. Several differential diagnoses can be mentioned such as laryngocoele, gill cyst, paraganglioma and hemangioma. They are of unknown etiology with several hypotheses on the etiopathogenesis and on the frequent localization on the right. Conservative treatment can be chosen for small aneurysms and in children. Surgical treatment finds its indication especially in the event of a complication such as thrombosis or for an aesthetic interest; other treatments such as endovascular treatment are being evaluated. We report the case of a 67-year-old woman admitted for a painful latero-cervical mass, and in whom the diagnosis of an aneurysm of the internal jugular vein was suspected and confirmed by ultrasound and CTscan. The patient received successful surgical treatment.

[Occlusion of the abdominal aorta in patients infected with the human immunodeficiency virus: Clinical case and review of the literature]. / Occlusion de l'aorte abdominale chez les patients infectés par le virus de l'immunodéficience humaine : cas clinique et revue de littérature.

HIV infection has now become a chronic disease with a good life expectancy thanks to antiretrovirals. The mortality currently is attributed to other pathologies in particular cardiovascular because of the inflammation and the side effects of the drugs. All arteries can be damaged in HIV, especially the aorta, with several types of lesions which can be occlusive, aneurysmal, dissecting, even with the cases of arteriovenous fistula which have been described. HIV occlusive arterial disease is different from atheromatous disease in HIV-free patients and this is confirmed by pathology and ultrasound studies, which makes it more difficult to manage HIV-related occlusions. The open surgical treatment especially in the acute forms is disappointing with complications of rethrombosis and infectious and of sepsis of prosthesis considering the immunosuppression, the endovascular treatment begins to become the treatment of choice in the aneurysmal pathology and probably it would be in the future for occlusive disease.

External jugular vein aneurysm: a rare cause of neck swelling. A report of three patients.

Venous aneurysms are a relatively rare pathology, far less common than arterial aneurysms. Unrelated to either age or gender, they can affect any vein, including cervical, thoracic, visceral, and lower limb veins. Aneurysmal dilatations in cervical veins are rare due to low pressure in the vena cava system; they can involve any vein but most frequently are observed on the internal and external jugular veins. This report of three patients highlights some of the specific diagnostic and therapeutic features of this pathology.

[Rupture of a popliteal artery pseudo-aneurysm revealing a tibial osteochondroma: case report and review of the literature]. / Rupture d'un faux anévrisme de l'artère poplitée révélant une exostose du tibia : à propos d'un cas et revue de littérature.

Osteochondroma constitutes the most frequent bone tumor. It is exceptionally responsible for vascular complications from which pseudo-aneurysms constitute the most frequent entity. We report the case of a 20-year-old patient who presented with acute pain of the left knee following a sports' accident. Vascular ultrasonography showed the rupture of a false aneurysm of the popliteal artery. An arteriography confirmed the diagnosis by showing contrast leakage at the level of the below-knee popliteal artery projecting over an osteochondroma. Surgery was undertaken to close the aneurysm an insert a venous graft. The procedure was completed by excision of the bone tumor. Vascular complications of osteochondroma are rare but should be considered in young patients with a false aneurysm of the popliteal artery. Surgery is required for the treatment of false aneurysms on exostosis.

[Vascular type of Ehlers-Danlos syndrome: a rare cause of spontaneous pseudo-aneurysms]. / Syndrome d'Ehlers-Danlos de type vasculaire : une cause rare de faux-anévrismes artériels spontanés.

We report a case of a 20-year-old-man who was admitted to our hospital through the emergency room for a swelling of the right thigh, which had appeared spontaneously without fever. The physical exam was highly suggestive of a vascular mass. The arterial CT scan of the right lower limb revealed a pseudo-aneurysm of a branch of the deep right femoral artery. The diagnosis of vascular type of Ehlers Danlos syndrome was established on clinical criteria. The successful management was surgical by the excision of the pseudoaneurysm and the ligation of the feeding branch that supplied the pseudoaneurysm. The postsurgical follow-up was uneventful and the clinical course was smooth with no further complications.

[Coeliac trunk aneurysm revealing Behçet disease (2 case reports)]. / Anévrisme du tronc coeliaque révélant la maladie de Behçet. A propos de deux cas.

The Behçet's disease is a vasculitis of an unknown origin. Vascular inflammatory lesions predominantly affect veins, potentially leading to superficial or deep thrombophlebitis. Arterial involvement is rare, mainly aneurysms. We display two case reports of patients where Behçet's disease is revealed by celiac trunk aneurysm. The symptoms are nonspecific. Ultrasound Doppler and angioscan are a key to the diagnosis. The two patients received medical and surgical treatment. By these two case reports, we insist that the diagnosis of Behçet's disease should be evoqued in any young patient with arterial aneurysm.
