Cytomegalovirus Infection-related Spontaneous Intestinal Perforation and Aorto-enteric Fistula after Abdominal Aortic Aneurysmal Repair / 대한소화기학회지

Gastrointestinal complications (GI) after thoracoabdominal aortic repair can be classified as biliary disease, heptic dysfunction, pancreatitis, GI bleeding, peptic ulcer disease, bowel ischemia, paralytic ileus, and aortoenteric fistula. Theses complications are associated with high post operative morbidity and mortality. Most of the aortoenteric fistulae after thoracoabdominal aortic surgery are found at the duodenum, near the surgical site. These rare complications are caused by an indirect communication with abdominal aorta that originated from an aneursymal formation ruptured into the duodenum. Such aorto-duodenal fistula formation is considered as a result of inflammatory change from secondary infection near the surgical instruments. Herein, we report two cases of massive upper GI bleeding from aorto-duodenal fistulae and spontaneous lower GI perforation related to cytomegalovirus infection after abdominal aortic aneurysmal repair operations.

Giant single left coronary artery with right ventricular fistula diagnosed in early childhood.

We present an unusual case of an 18-month-old boy, who presented with dyspnea and recurrent respiratory tract infections. Echocardiography and subsequent angiography were suggestive of a fistula from a coronary artery to the right ventricle. Finally, only on table could the actual diagnosis of a single left coronary artery with right ventricular fistula be made. Surgical treatment was successfully performed with off-pump ligation and the patient was well with no residual fistula on echocardiogram when seen at 3 month follow-up.

Spontaneous Closure of Iatrogenic Coronary Artery Fistula to Left Ventricle After Septal Myectomy for Hypertrophic Obstructive Cardiomyopathy

Cases of iatrogenic coronary artery fistulas draining into the left ventricle after surgical myectomy for hypertrophic obstructive cardiomyopathy have been published as sporadic reports. However, its management scheme and prognosis are not clear because of the low incidence. A 46-yr-old woman was hospitalized for evaluation of chest pain and shortness of breath for 3 months. Transthoracic echocardiographic examination showed typical hypertrophic obstructive cardiomyopathy with a peak pressure gradient of 71 mmHg across the left ventricular outflow tract. The patient underwent surgical septal myectomy. Postoperative color Doppler imaging revealed a diastolic blood flow from the interventricular septal myocardium to the left ventricular cavity, i.e. iatrogenic coronary artery fistula to the left ventricle. Ten days later, the fistula closed spontaneously which was diagnosed by transthoracic echocardiography and confirmed by coronary angiography.

A Case of Pancreaticoportal Fistula Associated with Acute Severe Pancreatitis / 대한소화기학회지

Pancreatic fistulas are usually caused by the disruption of pancreatic duct. The majority of pancreatic fistulas are external fistulas and common causes of external and internal pancreatic fistulas are trauma and surgery. Internal pancreatic fistulas due to pancreatitis are rare. Internal pancreatic fistulas may communicate with peritoneal cavity, colon, small bowel, biliary system or pleural cavity. Among them, fistula between pancreatic duct and portal vein due to acute pancreatitis is rare. We report a case of 32-year-old male with fistula between pancreatic duct and portal vein as a complication of acute pancreatitis. Pancreaticoportal fistula was diagnosed by endoscopic retrograde cholangiopancreatography. He recovered after distal pancreatectomy with splenectomy and supportive care.

Bioptome-assisted coil occlusion of coronary artery fistula.

We describe a novel technique that allows controlled and precise delivery of single or multiple coils simultaneously for occlusion of a coronary artery fistula using a bioptome passed via a long sheath positioned at the distal end of the fistula. The fistula was balloon occluded distal to the take-off of the native branches before, during and after coil delivery in two patients.

Fístula aorto-entérica primária / Primary aortoenteric fistula

A fístula aorto-entérica primária (FAEP) é uma entidade clínica extremamente rara, geralmente associada a doenças infecciosas prévias ou congênitas. Elas ocorrem predominantemente na terceira ou quarta porção do duodeno. A sintomatologia habitualmente consiste em dor abdominal, hamatêmese, melena e massa abdominal. Este caso refere-se a uma paciente com evolução de seis episódios de hemorragia digestiva alta em um período de cinco meses. Os autores revisam a literatura, discutem a enfermidade e relatam a história clínica, a propedêutica armada e o tratamento empregado

Múltiplas fístulas das artérias coronárias ao ventrículo esquerdo / Multiple Coronary Artery to Left Ventricle Fistulae

A 51 year-old man was admitted to the coronary care unit due an episode of retroestenal pain with ischaemic alterations in electrocardiogram. It was made the diagnosis of unstable angina. Cinecoronariography showed dilated coronary arteries without obstructions and multiples coronary fistulas draining into left ventricular cavity. Transesophagic echocardiogram with microbubbles injection into coronary arteries showed an important coronary steal phenomena. It is discussed the diagnosis and the treatment. This is one of the rare cases of coronary fistulas draining into the left ventricular cavity and the first one with alterations in the rest ECG.
