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...

CLINICAL INTRODUCTION: A 59-year-old woman visited an outpatient cardiology clinic due to shortness of breath on exertion. Physical examination showed no significant abnormality of vital signs. A III/VI systolic murmur was heard on the fourth intercostal space at the right sternal border. The majority of laboratory tests were normal. Chest X-ray showed a curved vessel shadow (figure 1A). Initial transthoracic echocardiography showed abnormal blood flow into the inferior vena cava (IVC) in the subxiphoid long axis view (figure 1B) and mild right heart dilatation (online supplementary figure 1)...

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...

Objective To reach consensus on which complications of varicose vein treatments physicians consider major or minor, in order to standardize the informed consent procedure and improve shared decision-making. Methods Using the e-Delphi method, expert physicians from 10 countries were asked to rate complications as "major" or "minor" on a 5-point Likert scale. Reference articles from a Cochrane review on varicose veins were used to compose the list of complications. Results Participating experts reached consensus on 12 major complications: allergic reaction, cellulitis requiring intravenous antibiotics/intensive care, wound infection requiring debridement, hemorrhage requiring blood transfusion/surgical intervention, pulmonary embolism, skin necrosis requiring surgery, arteriovenous fistula requiring repair, deep venous thrombosis, lymphocele, thermal injury, transient ischemic attack/stroke, and permanent discoloration...

We present two cases of females in their 40s presenting with biventricular heart failure being the consequence of a large arteriovenous fistula. Both patients had undergone abdominal surgery several years prior to the heart failure event with the initial finding of moderate pulmonary hypertension and high-output heart failure. CT revealed a large arteriovenous fistula between the common iliac artery and vein which subsequently was closed percutaneously.

Arteriovenous fistula (AVF) is regarded as the best vascular access for chronic haemodialysis (HD). Still, AVF inherently causes significant haemodynamic changes. Although the necessity for vascular access despite its putative cardiovascular complications favours AVF creation in patients under chronic HD, one may question whether sustaining a functional AVF after successful kidney transplantation extends the haemodynamic threat. Small prospective series suggest that AVF ligation causes rapid and sustained reduction in left ventricular hypertrophy...

Congenital pulmonary arteriovenous fistulae occur as a result of abnormal blood vessel development in the lungs. Blood takes a short pass from the pulmonary artery to veins. Multiple pulmonary arteriovenous fistulae are a rare occurrence, especially when involving both lungs. Fistulae located at the edge are prone to rupture and bleeding. We discuss a case of a 15-year-old overweight male with multiple pulmonary arteriovenous fistulae successfully treated with wedge-shape excision via video-assisted thoracoscopic surgery...

A 74-year-old woman underwent abdominal computed tomography for screening, and a right large aneurysmal-type renal arteriovenous fistula (AVF) was found incidentally. The venous sac of the renal arteriovenous fistula was enlarged, and coil embolization was considered. To prevent severe complications such as coil migration, pulmonary embolism, and rupture during procedure, coil embolization was approached via both the feeding artery and the draining vein simultaneously, with balloon occlusion of the feeding artery...

Aneurysms associated with arteriovenous fistulas (AVFs) are rare but can cause significant morbidity. They are often diagnosed after rupture, pain, or embolization. We describe a unique case of a 35-year-old woman with a large iliac vein aneurysm related to an acquired AVF incidentally discovered on ultrasound during pregnancy. She had a diagnosis of "idiopathic" pulmonary hypertension for several years. This report details the diagnosis and treatment with an arterial stent graft that was effective in decreasing the size of the venous aneurysm and reversing the systemic changes associated with the disease...

Primary iliac venous aneurysm is an exceedingly rare abnormality that can be complicated by pulmonary embolism, thrombosis, and rupture. Here we report the case of an otherwise healthy 40-year-old man with a unilateral external iliac vein aneurysm without any evidence of an arteriovenous fistula, proximal stenosis, or obstruction, as reported on computed tomography. Pulmonary embolism was diagnosed using 99m Tc-macroaggregated albumin scintigraphy. To prevent life-threatening complications, we treated the patient with anticoagulant therapy and performed aneurysmectomy with reconstruction using a saphenous vein graft patch...
