The Fontan procedure is an open heart procedure performed in pediatric patients with a particular congenital cardiac anomaly known as a univentricular heart. The procedure is used to reroute the systemic venous blood from the inferior vena cava directly to the pulmonary artery. It improves patients' prognoses, but various late-phase extracardiac complications that manifest when patients reach adolescence have been recognized. These complications, pulmonary arteriovenous fistula and protein losing gastroenteropathy, for example, present significant challenges in the management of adults with Fontan circulation...

Portopulmonary hypertension (PoPH) is a well-recognized complication of portal hypertension. This study reports a case of portopulmonary hypertension that was secondarily caused by post-traumatic mesenteric arteriovenous fistula. A 38-year-old man with a history of knife stabbing wounds in the abdomen in 2003 was admitted to the hospital with exertional shortness of breath and a mechanic murmur over the umbilical region. Computed Tomography indicated signs of portopulmonary hypertension and mesenteric arteriovenous fistula...

The most frequent dialysis modality in Switzerland is hemodialysis. Patients need a proper vascular access for this modality. There are three types of vascular access for hemodialysis : arteriovenous fistula, arteriovenous graft and central venous catheters. In this article, we will discuss the most important parameters that need to be taken into account when choosing the most appropriate access. We present the advantages and disadvantages of each vascular access, as well as their main local (thrombosis, infection, steal syndrome) and systemic (heart failure, pulmonary hypertension) complications, which may also be encountered by primary care physicians...

Pulmonary hypertension is a known complication of high-flow arteriovenous fistulas (AVFs). We present a case of a 58-year-old man who sustained a gunshot wound 6.5 years before presentation for worsening pulmonary hypertension (PH). After diagnostic workup, the PH was attributed to a gunshot-related AVF. Exercise capacity and echocardiographic parameters improved after successful ligation of the AVF. This case highlights a rare and correctable cause of PH that requires careful investigation and multidisciplinary expertise for treatment...

BACKGROUND: Abernethy malformation is an extremely rare congenital malformation characterised by an extrahepatic portosystemic shunt. Children with Abernathy malformation can develop hepatopulmonary syndrome (HPS) with pulmonary arteriovenous fistulas (PAVF) or pulmonary hypertension. PAVF manifests as central cyanosis with effort intolerance. We report a case of PAVF in a Ten-year-old Boy. Persistent symptoms identified Abernathy malformation as the cause of progressive symptoms and current understanding of this rare malformation is reviewed...

RATIONALE: Complex pulmonary arteriovenous fistula (PAVF) is unusual, and even rarer in 2 members of a family. PAVF may not appear on chest X-ray or computed tomography imaging, especially in asymptomatic patients, and therapy is limited. Herein, PAVFs occurring in a mother and daughter are described, with the current standard methods of diagnosis and treatment of PAVF. PATIENT CONCERNS: A 34-year-old woman and her 13-year-old daughter presented with light cyanosis of the nail beds but were otherwise asymptomatic, and physical examination was unremarkable...

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant inherited Rare Disease that causes a systemic anomalous vascular overgrowth. The approach and follow-up of these patients should be from multidisciplinary units. Its diagnosis is carried out according to Curaçao clinical Criteria. Telangiectasia in the nasal mucosa cause recurrent epistaxis, the main symptom of HHT and difficult to control. The three types of hepatic shunting, hepatic artery to hepatic vein, hepatic artery to portal vein or to portal vein to hepatic vein, can cause high-output heart failure, portal hypertension or porto-systemic encephalopathy, respectively...

BACKGROUND Pulmonary thromboembolism (PTE) sometimes leads to a shock state and sudden death due to acute massive pulmonary arterial thrombosis. The origins of pulmonary arterial thrombi are varied, but most arise from deep vein thrombosis. We herein presented a very rare cause of PTE due to paradoxical embolism caused by arteriovenous fistula from common iliac artery to common iliac vein. CASE REPORT A 74-year-old man was admitted because of increasing dyspnea on exertion. The diagnosis of idiopathic pulmonary fibrosis was made and corticosteroid therapy was started...

Complications arising from a functional arteriovenous fistula (AVF) in successful kidney transplant recipients (KT) have been overlooked despite some reports of its deleterious effect on heart, lungs, and kidney allograft. As such, there is no consensus regarding management of AVF after renal transplantation. We report Cardio-Renal Syndrome Type 5 in kidney transplant recipients who presented with a clinical syndrome of shortness of breath, edematous state, kidney allograft dysfunction, and high pulmonary pressure 3-8 months after successful transplantation...

Medullary hemorrhage is quite rare among brain stem hemorrhage cases, thus the clinical course remains unclear. In the medulla oblongata, respiratory centers are located and previous reports indicate that medullary lesions have possible relationship with acute respiratory distress syndrome. This kind of respiratory failure is commonly caused by neurogenic pulmonary edema (NPE), which is defined as noncardiac noninfectious acute respiratory distress syndrome with changes in intracranial condition including cerebrovascular events...

Coronary arteriovenous (AV) fistulae are rare congenital anomalies and encompass a wide variety of communications between the coronary artery and the pulmonary or systemic vasculature. Symptoms depend on the presence and severity of myocardial malperfusion secondary to coronary artery steal phenomenon at rest or exertion. These fistulae are traditionally treated by open surgery. Endovascular therapy has been reported with the use of fibered coils. We report a case of a large left anterior descending (LAD) coronary artery to the main pulmonary artery fistula that was incidentally discovered during a pre-operative work up in a 28-year-old woman...
