Fístula aorto-atrial direita: uma complicação pós-endocardite infecciosa. Relato de caso / Right aorto-atrial fistula: a post-infective endocarditis complication. A case report

A fístula aorto-atrial direita é uma comunicação anômala, que representa uma grave e infrequente complicação da endocardite infecciosa. Neste estudo, relata-se o caso de um paciente de 53 anos, do sexo masculino, com histórico evolutivo patológico de endocardite infecciosa e acometimento de valva aórtica. Sob imagem de ecocardiograma, demonstrou-se abscesso perivalvar aórtico, estendendo-se à parede atrial direita, com necessidade de abordagem cirúrgica. Foram realizados a anuloplastia valvar aórtica e implante de valva mecânica. Após 1 mês de evolução pós-cirúrgica, realizou-se novo ecocardiograma, que acusou shunt de débito da raiz da aorta para o átrio direito. A conduta diante do caso foi discutida entre equipe clínica e cirúrgica, visando a possíveis falhas na terapêutica inicial. (AU)

Right aorto-atrial fistula is an anomalous communication that represents a serious and infrequent complication of infective endocarditis. This study reports the case of a 53-year-old male patient, with a pathological evolutionary history of infective endocarditis and aortic valve involvement. The echocardiogram shows an aortic perivalvar abscess extending to the right atrial wall, requiring a surgical approach. Aortic valve annuloplasty and mechanical valve implantation were performed. After a month of post-surgical evolution, a new echocardiogram was performed, which showed aortic root to right atrium shunt. The behavior in this case was discussed between the clinical and surgical teams, aiming at possible failures in the initial therapy. (AU)

Primary aortoduodenal fistula: first you should suspect it

ABSTRACT A 59 year-old patient was admitted with upper gastrointestinal bleeding. The clinical exam showed mild hypotension and blood samples revealed acute anemia (hemoglobin = 7.5 g/dl). Emergency computed tomography showed an infrarenal abdominal aortic aneurysm and extravasation of the arterial contrast material toward the digestive tract. The patient was transported to the operating room for emergency laparotomy, which showed an aortoduodenal fistula. After proximal and distal aortic vascular control, the two anatomical structures were dissected with duodenorrhaphy, patch repair of the aortic tear and omentum interposition. The postoperative recovery was uneventful, with discharge after 12 days.

Embolization of congenital intrahepatic porto-systemic shunt by n-butyl cyanoacrylate.

Congenital intrahepatic portosystemic venous shunt (IHPSVS) is rare vascular anomaly. We present one case of a 14- month male child who presented with global developmental delay. Child had high ammonia levels with low glutamine and high bile salts on the previous investigations and had history of neonatal seizures since day 13 of life. On admission, serum ammonia levels were elevated to 112μmol/L. Other laboratory investigations including liver and renal function test, and electrolytes were normal. He was, diagnosed to have IHPSVS on the basis of Doppler and CT, and treated by embolization with n-butyl cyanoacrylate (glue). A brief review of diagnostic modalities and endovascular management for the IHPSVS is presented including the present case.

Hepatic myelopathy as a presenting neurological complication in patients with cirrhosis and spontaneous splenorenal shunt / 대한간학회지

Hepatic myelopathy is a rare complication of chronic liver disease that is associated with extensive portosystemic shunts. The main clinical feature of hepatic myelopathy is progressive spastic paraparesis in the absence of sensory or sphincter impairment. Early and accurate diagnosis of hepatic myelopathy is important because patients with early stages of the disease can fully recover following liver transplantation. Motor-evoked potential studies may be suitable for the early diagnosis of hepatic myelopathy, even in patients with preclinical stages of the disease. Here we describe two patients who presented with spastic paraparesis associated with a spontaneous splenorenal shunt and without any previous episode of hepatic encephalopathy. One patient experienced improved neurologic symptoms after liver transplantation, whereas the other patient only received medical treatment, which did not prevent the progression of spastic paraparesis.
