Subclavian and axillary arterial aneurysms: two case reports / Aneurismas do segmento subclavio-axilar: relato de dois casos

Aneurysms of the subclavian-axillary segment are rare, but when diagnosed they must be treated. This article describes two cases of aneurysms of the upper extremities, one in a subclavian artery and the other in an axillary artery. The first case was a 71-year-old male with a pulsating supraclavicular bulge on the right and muscle weakness in the ipsilateral extremity. Duplex scanning and arteriography confirmed the diagnosis of aneurysm of the right subclavian artery and the patient underwent aneurysmectomy and end-to-end anastomosis. The second case was a 24-year-old female patient, with no history of comorbidities, who presented with a pulsating mass in the right axillary region and paresthesia of the ipsilateral extremity. Duplex scanning and arteriography confirmed an aneurysm in the right axillary artery, which was successfully treated with aneurysmectomy and end-to-end anastomosis. Pathology findings showed that the first case was an atherosclerotic aneurysm and the second was a congenital aneurysm.

Os aneurismas do segmento subclávio-axilar são de ocorrência rara e, uma vez diagnosticados, devem ser tratados. Neste trabalho, relatamos dois casos de aneurismas de membros superiores, sendo um da artéria subclávia e outro da artéria axilar. No primeiro caso, o paciente de 71 anos, sexo masculino, apresentava abaulamento pulsátil supraclavicular direito associado à fraqueza muscular no membro ipsilateral. Foram realizados duplex scan e arteriografia, que confirmaram o diagnóstico de aneurisma da artéria subclávia direita, sendo o paciente submetido à aneurismectomia com anastomose término-terminal. No segundo caso, uma paciente de 24 anos, do sexo feminino, sem antecedentes mórbidos ou comorbidades, apresentava queixa de massa pulsátil na região axilar direita associada à parestesia no membro ipsilateral. O duplex scan e a arteriografia confirmaram o aneurisma da artéria axilar direita, que foi tratado com aneurismectomia e anastomose término-terminal com sucesso. O diagnóstico anátomo-clínico foi de aneurisma aterosclerótico no primeiro caso e, no segundo caso, de aneurisma congênito.

Prenatal sonographic diagnosis of congenital ductus arteriosus aneurysm: a case report.

The objective of this report was to demonstrate prenatal sonographic features of congenital ductus arteriosus aneurysm (DAA), a rare, but possibly fatal abnormality. It is characterized by a saccular or fusiform dilatation of the ductus arteriosus. The majority of affected neonates are clinically asymptomatic and tend to progressively diminish in size of DAA and spontaneous closure. However, serious complications can occur during waiting periods, including spontaneous rupture or thromboembolism. Case: A 35 year-old Thai woman, G2P1, underwent ultrasound examination at 34 weeks' gestation. Fetal echocardiography revealed markedly enlarged and tortuous ductus arteriosus with saccular dilation at the distal end, just before joining the descending aorta. The cross-sectional diameter of the saccular portion of the ductus arteriosus was 10 mm. The active female baby was vaginally delivered at 34 weeks' gestation, weighing 1050 grams. Postnatal echocardiography confirmed the prenatal findings. The DAA was gradually decreased in size and finally spontaneously closed without medical or surgical intervention.

Giant left atrial appendage aneurysm: a case report

A 21-year-old male was referred to the cardiology clinic at Queen Alia Heart Institute for further evaluation upon finding a trial fibrillation and abnormal chest X-ray and on a routine pre-recruitment medical check-up. Trans-thoracic echocardiography suggested the diagnosis of left a trial appendage aneurysm versus pericardial cyst. Transesophageal echocardiography and subsequent cardiac catheterization confirmed the presence of a giant left a trial appendage aneurysm. He underwent uneventful surgical excision. Cardiac rhythm reverted spontaneously to sinus rhythm that was maintained twelve months later

L' imagerie medicale dans l'ane'vrisme congenital du tronc porte [a' propos d'un cas]

Aneurysmal malformation of the portal vein is rather rare. A 6/3cm aneurysmal malformation of the intra and extra-hepatic portal vein, thought to be of congenital origin is described. A literature review yielded only thirty similar cases, most of them being associated with hepatopathy or pancreatic pathology. Congenital forms are exceptional. Radiologic findings and a literature review are described [real time ultrasohography computed tomography and magnetic resonance imaging]
