[False aneurysm of the external iliac artery revealing Behçet's disease]. / Faux anévrysme de l'artère iliaque externe révélant une maladie de Behçet.

Behçet's disease is a vasculitis of unknown etiology. Vascular involvement is rare, but may be inaugural in many cases. We report a case of Behçet's disease revealed by a symptomatic pseudo-aneurysm of the external iliac artery. The symptomatology was non-specific. Ultrasound Doppler and computed tomographic angiography were essential for diagnosis. The pseudo-aneurysm was managed by endovascular treatment. Corticosteroid and immunosuppressant therapy were administrated after surgery.

[Internal carotid aneurysm of dysphasic origin]. / Un anévrisme de l'artère carotide interne d'origine dysplasique.

Extracranial carotid aneurysms are rare, but are of significant clinical interest due to the high risk of cerebral embolism. Despite considerable progress in endovascular techniques, surgical treatment of these aneurysms remains the golden standard. We report the case of a 50-year-old man who presented an aneurysm of the left internal carotid artery measuring 46 × 26 mm. Resection of the aneurysm with interposition of a prosthetic graft was performed. The postoperative course was uneventful. Pathology reported that the aneurysmal sac probably had a dysplastic origin.

[False traumatic aneurysm of the ulnar artery in a teenager]. / Faux anévrysme traumatique de l'artère ulnaire chez un adolescent.

Most aneurysms of hand arteries are traumatic. It is a generally rare unrecognized pathology. Complications are serious (embolism and thromboses of interdigital arteries). Two main causes can be recalled: acute trauma, with development of a false aneurysm; repeated microtrauma (hand hammer syndrome), with occurrence of an arterial dysplasic aneurysm. The diagnosis is based on the presence of a pulsatile mass, with finger dysesthesia, unilateral Raynaud's phenomenon. It is confirmed by duplex Doppler. Arteriography is necessary but can be replaced by an angio-MR. We report a case of false traumatic aneurysm of the ulnar artery in a teenager. This case illustrates this rare condition and opens discussion on therapeutic options.

[Tripe palms and a hypertrophic osteoarthropathy syndrome revealing a neuroendocrine carcinoma of the lung]. / Pachydermatoglyphie associée à une ostéoarthropathie hypertrophique révélant un carcinome neuroendocrine du poumon.

BACKGROUND: Tripe palms is a rare cutaneous paraneoplastic syndrome, primarily evocative of lung and gastric neoplasia. Association of many paraneoplastic diseases has also been reported. PATIENTS AND METHODS: A 49-year-old man with a history of alcoholism and smoking addiction reported haemoptysis and thoracic pains present for one year. The physical examination showed left lung condensation. The skin examination revealed a thickened yellowish keratoderma with exaggerated skin ridges and digital clubbing. A diagnosis of paraneoplastic tripe palms was made, prompting repetition of the biopsy which ultimately revealed a neuroendocrine carcinoma. Skeletal scintigraphy showed periosteal proliferation with hypertrophic osteoarthropathy. COMMENTS: "Tripe palms" or "osteoarthritic acanthosis" is a paraneoplastic syndrome. It involves an acquired keratoderma taking on a yellow velvety appearance with accentuation of dermatoglyphic lines. Malignancy is discovered in over 90% of individuals with tripe palms. If malignancy is isolated, it mostly involves the lung (53%). Gastric cancer is associated in 77% of cases if the condition is associated with acanthosis nigricans. In approximately one third of cases, the keratoderma may resolve, generally after treatment of the tumour. The association of many paraneoplastic syndromes has also been reported, in particular digital clubbing and hypertrophic osteoarthropathy. At least 90% of cases of hypertrophic osteoarthropathy in adults occur in patients who have or will eventually develop a malignancy. It is characterized by periostosis of long bones, joint pain, and clubbing, and it is often seen on bone scintigraphy during staging of lung carcinoma.

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.

[Acute lower limb ischemia revealing acute leukemia. Case report and review of the literature]. / Ischémie aiguë du membre inférieur révélant une leucémie aiguë. A propos d'un cas et revue de la littérature.

Large vessel thrombosis is a very rare clinical presentation of acute leukemia which is usually revealed by hemorrhagic complications or thrombosis of small vessels. We present here the case of a patient with previously undiagnosed acute myeloid leukemia who was referred to our hospital with symptoms of acute ischemia of the left lower limb. Occlusion of the left popliteal artery due to a leucostasis was noted and successfully treated with emergency surgical thromboembolectomy and chemotherapy.

[Left atrial myxoma: a rare cause of acute occlusion of the aorta. Case report and review of the literature]. / Myxome de l'oreillette gauche : une cause rare d'occlusion aiguë de l'aorte. A propos d'un cas et revue de la littérature.

We present an observation of a 42-year-old patient admitted in urgency for lower limbs weakness followed by paralysis. At physical examination the lower limbs were cold. Pulses of the lower limbs could not be palpated. Color Duplex ultrasonography revealing an embolus occluding both the infrarenal aorta and bilateral iliac arteries. The aortoiliac embolus was removed by balloon endarterectomy through the femoral arteries with evacuation of a transparent, gelatinous embolus followed by extensive fasciotomies. Two-dimensional echocardiography showed a mass in the left atrium. Pathological examination of the material embolic confirmed the diagnosis of the cardiac myxoma. The clinical course was marked by the development of a syndrome of revascularization; death occurred the fourth day of hospitalization. This case highlights the need for pre- and perioperative measures to be taken to overcome hyperkalemia and acute renal failure when revascularizing acute, massive, prolonged ischemia of the lower body.

[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.

[Multiple tuberculous aortic aneurysms in a child. A case report]. / Multiples anévrismes aortiques d'origine tuberculeuse chez un enfant. A propos d'un cas.

INTRODUCTION: Tuberculous aortic aneurysms are rarely seen. Their major complication is unforeseeable and lethal aneurysmal rupture. We report an exceptional case of multiple tuberculous aortic aneurysms in a child. CASE REPORT: A 13-year-old girl was admitted to our hospital with abdominal pain. She reported a history of fever, night sweats and weight loss. Physical examination showed a pulsatile mass over the umbilicus. Thoracoabdominal angio-NMR revealed multiple pseudoaneurysms of the thoracic and abdominal aorta. The patient underwent elective laparotomy, resection of the abdominal aortic and in situ prosthetic repair with an aortic graft. The postoperative recovery was uneventful. The histopathologic examination of the aortic wall and para-aortic lymph nodes showed evident features of tuberculosis. Antituberculous chemotherapy was initiated. CONCLUSION: Tuberculous aortic aneurysms are rarely seen. Their major complication is rupture. Surgery must not be delayed just like antitubercular therapy.

[Giant aneurysm of the splenic artery. Case report and review of the literature]. / Anévrisme géant de l'artère splénique. A propos d'un cas et revue de la littérature.

INTRODUCTION: Giant splenic artery aneurysm is exceptional. We report a case and review the literature to ascertain the characteristic epidemiological, clinical and therapeutic features of this condition. CASE REPORT: A 62-year-old man was admitted for epigastric pain. Physical examination found an epigastric pulsatile mass. A contrast computed scan of the abdomen revealed a 10-cm thrombosed aneurysm of the splenic artery. An abdominal aortography, including selective celiac angiography, confirmed the presence of a 10-cm aneurysm originating from the medial third of the splenic artery. The patient underwent open surgical repair. The proximal and the distal splenic artery were ligated from within the aneurysm. The postoperative period was uneventful. CONCLUSION: Giant aneurysm of the splenic artery is a rare clinical entity. These aneurysms differ from usual splenic artery aneurysms in several ways involving the predominant gender, localization on the splenic artery, clinical presentation, and treatment.
