Abstract A rare case of a pulmonary arterio-venous malformation not requiring treatment is reported. An incidental peripheral right lower lobe intrapulmonary was identified on computed tomography. On catheter angiography, no artery supply identified. Systemic arteriography systemic arterial from conjoined inferior phrenic with venous drainage to the left atrium. Due this lung abnormality being ...

PURPOSE To define the diagnostic precision of non-specialized readers in the detection of type 2 endoleaks (T2EL) in arterial versus venous phase acquisitions, and to evaluate an approach for radiation dose reduction. METHODS The pre-discharge and final follow-up multi-slice CT angiographies of 167 patients were retrospectively analyzed. Image data were separated into an arterial and a venous...

We performed pulmonary venous occlusions in order to check the validity of the pulmonary capillary pressure measurements obtained using pulmonary arterial occlusion in the intact animal. The venous and arterial postocclusion pressure profiles were recorded using balloon catheters introduced, respectively, into a left lower lobe vein and into a right pulmonary artery in the anaesthetized open-ch...

Thromb Haemost 2008; 100: 181–183 Venous and arterial thromboembolic disorders are usually considered as two distinct disease entities.At first this belief appears to be indisputable. Arterial thrombi consist mainly of platelets and are induced by arterial plaque ruptures which tend to occur at sites where shear rates are high. Conversely, venous thrombi mainly consist of red blood cells and fi...

Initial imaging of pancreatic ductal adenocarcinoma is of crucial importance in the decision-making process. The aim of this study was to compare preoperative imaging, pathological data, and outcomes in a series of patients who underwent resection for pancreatic head cancer.From January 2004 to December 2009, data were collected by the Association Française de Chirurgie on 1044 patients who rec...

The objectives of the present review are to describe the agreement between variables on arterial and venous blood gas analysis (in particular pH, pCO(2) , bicarbonate and base excess) and to identify unanswered questions. MEDLINE search of papers published from 1966 to January 2010 for studies comparing arterial and peripheral venous blood gas values for any of pH, pCO(2) , bicarbonate and base...

In neonatology, blood gas analysis is a useful tool in the evaluation of the health of newborns and plays a key role in early detection of critically ill subjects. Because blood gas analysis parameters have not previously been studied in any depth in donkey foals, this study was performed on 16 healthy Martina Franca donkey foals born after an uncomplicated delivery. Arterial and venous blood s...

Formation of the yolk sac vascular system and its connection to the embryonic circulation is crucial for embryo survival in both mammals and birds. Most mice with mutations in genes involved in vascular development die because of a failure to establish this circulatory loop. Surprisingly, formation of yolk sac arteries and veins has not been well described in the recent literature. Using time-l...

PURPOSE The purpose of this study was to define the influence of feeding mean arterial pressure (FMAP) in conjunction with other morphological or clinical risk factors in determining the probability of hemorrhagic presentation in patients with cerebral arteriovenous malformations (AVMs). METHODS Clinical and angiographic data from 340 patients with cerebral AVMs from a prospective database we...

1. A simple method for arterial puncture is given which does no permanent injury to the artery. Arterial and venous punctures have been done on 33 cases of pneumonia and five normal subjects, and the blood thus obtained has been studied with reference to the oxygen capacity and arterial and venous unsaturation. 2. In five normal subjects the mean arterial unsaturation was 5 per cent of the tota...
