Arteriovenous fistulas can lead to a number of different chronic complications. We describe a case where a patient developed a thrombosis within her brachiobasilic arteriovenous fistula, which was manually manipulated in order to restore fistula flow. This resulted in a pulseless electrical activity cardiac arrest within a few minutes. After ten minutes of chest compressions and intubation, there was return of spontaneous circulation. No epinephrine was given nor shocks administered. Patient was extubated within minutes and was alert, orientated and haemodynamically stable...

Pulmonary arteriovenous fistula (PAVF) is a complication of the Glenn shunt. A 57-year-old tetralogy of Fallot (TOF) patient, who had undergone a Glenn shunt and TOF total correction, complained of dyspnea and cyanosis. PAVFs were present in the right lung, and right lung perfusion was nearly absent. After coil embolization, takedown of the Glenn shunt, and reconstruction of the right pulmonary artery, the patient's symptoms were relieved. Extrapulmonary radioisotope uptake caused by the PAVFs shown in lung perfusion scans decreased, and right lung perfusion increased gradually...

Anomalies of the coronary arteries mainly concern a pediatric population, bringing together a wide range of defects. In adults, the evolution is linked to the hemodynamic consequences of fistula. Several therapeutic options have been proposed such as surgery or embolization. We report the case of a 55 years old patient addressed because of dyspnea secondary to aortic insufficiency. The preoperative assessment shown the coexistence of coronary abnormality corresponding to a coronaro-pulmonary fistula. This type of coronary anomaly is rarely described in the adult population, because of its consequences secondary to the closure of the foramen ovale, resulting in angina symptoms in childhood...

We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

Coronary artery fistula (CAF) is a rare anomaly of the coronary artery. The draining site of a right coronary artery (RCA) fistula may usually be the right ventricle, right atrium, or pulmonary artery. Here, we present a patient with right coronary artery to coronary sinus fistula (RCACSF) complicated by aneurysmal dilatation of the coronary sinus (CS) and stenosis of CS ostium.

We describe a case involving a successful Fontan procedure for the treatment of pulmonary arteriovenous fistulas in a patient with polysplenia. The patient was diagnosed with bilateral superior vena cavae, interrupted inferior vena cava with azygos connection, wide separate hepatic veins, and central pulmonary artery stenosis following repair of a non-confluent pulmonary artery. Bilateral extracardiac conduits were used to connect each hepatic vein to the pulmonary artery, opposite each superior vena cava. Clinical improvement in the pulmonary arteriovenous fistulas was observed within 4 months after surgery...

BACKGROUND: Takayasu arteritis (TA), also known as aortoarteritis and pulseless disease, is an autoimmune, idiopathic, large-vessel vasculitis that primarily affects the aorta and its major branches, the coronary arteries, and the pulmonary arteries. METHODS: This is a peculiar clinical and radiological pattern of TA in a young female Caucasian. Her medical history included diagnosis of ulcerative rectocolitis at the age of 14. Because of the occurrence of anemia and exacerbation of rectocolitis, she had started infliximab associated with low doses of cortisone and mesalazine...

Salvage surgery is a relatively new entity in thoracic surgery and oncology. Salvage resection after radiotherapy refers to surgery as only remaining therapeutic option in patients who were treated with high-dose stereotactic radiotherapy (SRT) for early-stage lung cancer or full-dose chemoradiation for locally advanced lung cancer. Indications include locally progressive tumors, recurrent local or locoregional disease, or specific complications after radiotherapy such as lung abscesses or infected, necrotic cavities...

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy...

BACKGROUND: Considering that pneumonectomy itself is a disease, avoidance of pneumonectomy needs to be deliberated. Herein, we evaluated the role of neoadjuvant chemoradiotherapy for avoidance of pneumonectomy in patients with centrally located locally advanced non-small cell lung cancer. METHODS: Patients who underwent neoadjuvant chemoradiotherapy after being judged to require pneumonectomy by cancer board between 1997 and 2011 were retrospectively evaluated. RESULTS: Twelve patients, including 10 males and 2 females with median age 63...

RATIONALE: Numerous types of flap coverage have been reported to prevent or to repair bronchopleural fistulas. Most of the flaps were harvested from chest area. However, these pedicled flaps might not be optimal for the patient who has undergone previous radiotherapy on pulmonary parenchyma because the pedicle artery of the flap might have been injured by irradiation. Therefore, an alternative flap outside of the chest area is necessary. PATIENT CONCERNS: A 61-year-old male was diagnosed of squamous cell carcinoma in right upper lobe lung (cT3N2M0, stage IIIa)...

BACKGROUND: People living with HIV-1 infection are at greater risk for cardiovascular disease than seronegative adults. Treatment of dyslipidaemia with statins has been challenging in people with HIV because of an increased potential for drug interactions due to competing cytochrome P450 metabolism between statins and commonly used antiretroviral agents. Neither pitavastatin nor pravastatin depend on cytochrome P450 for primary metabolism. We aimed to assess the safety and efficacy of pitavastatin versus pravastatin in adults with HIV and dyslipidaemia...

INTRODUCTION: Cor triatriatum is a congenital cardiac anomaly in which the left (sinister) or right (dexter) atrium is divided into two compartments by residual embryonic tissue, resulting in a tri-atrial heart. As cor triatriatum dextrum can present clinically in various ways and have multiple associated cardiac anomalies, this report attempts to contribute to what is known about this exceedingly rare disorder. CASE: A 40 year old Hispanic man with a medical history of gastritis presented with complaints of palpitations, dizziness and bilateral lower extremity edema...

False aneurysm of the pulmonary artery complicated by bronchovascular fistula formation represents a rare life threating condition. We report a case of fatal hemoptysis after formation of a bronchial fistula in the late postoperative period after sleeve lobectomy. Cause of death was determined by external postmortem examination, post mortem computed tomography (PMCT) and angiography (PMCTA) without conventional autopsy.

Coronary artery anomalies constitute a diverse group of abnormalities, ranging from anatomic variants to those having hemodynamic consequences. This review focuses on major anomalies that have clinical implications requiring treatment, including anomalous origin of the coronary artery from the opposite sinus with interarterial course specifically with an intramural course, coronary artery origin from the pulmonary artery, and coronary artery fistula. Comprehensive imaging evaluation is necessary to precisely delineate the anatomy as well as pathophysiologic aspects of the anomaly before determining treatment options for a specific patient...

Massive hemoptysis is a medical emergency and needs immediate treatment. It occurs in a wide variety of pulmonary diseases and typically originates from the bronchial arteries. We herein report a very rare case of a patient bleeding from a right phrenic artery-to-pulmonary artery fistula accompanied with focal bronchiectasis in the right middle lobe of the lung. In this case, multi-detector computed tomography was useful for clarifying the etiology and the abnormal anastomosis and facilitated effective angiographic embolization...
