The geographical distribution of the four human malaria parasite species–Plasmodium falciparum, P. vivax, P. malariae and P. ovale is variable and is dependent on a number of factors such as season, endemicity and vector distribution. P. vivax is the most widely distributed and the most common species observed in temperate regions of the world, while P. falciparum is the most widespread through...

Microanigiographlic examinatioin of the pulmoniary arterial svstem in 12 n1ewborn in1fants with conicomitanit steniosis or atresia of the aortic anid mitral orifices showed that the intrapulmonary arterial pattern is inifluenced by the state of the forameni ovale. In inifanlts with aortic atresia with a prematuirely closed foramein ovale, that is cases in which the left side of the heart is a c...

A 75-yr-old female presented with platypnoea and orthodeoxia, shortly after laying down an old and pinching corset. The injection of activated Haemaccel in the right cubital vene during transoesophageal echocardiography, in the upright position, revealed a direct blood flow from the superior caval vein at a patent foremen ovale, consequently opening it and causing a large right-to-left shunt wh...

Transcatheter closure of patent foramen ovale is routinely performed using the transfemoral approach, which is safe and technically easy. Our case represents the rare situation where the procedure needs to be performed using the right internal jugular venous approach. According to our best knowledge this is the first report of a patent foramen ovale closure procedure with access through the int...

Approximately 40% of ischemic strokes have no clearly definable etiology and are termed cryptogenic strokes. Patent foramen ovale, a small communication between the left and right atria, is considered to be a risk factor for cerebral embolism. In this study, we report the case of a 29-year-old woman with diagnosis of ischemic stroke due to patent foramen ovale who has undergone percutaneous end...

Patent foramen ovale is frequently associated with embolic cerebrovascular accidents. The diagnosis of patent foramen ovale (PFO) is easier since the advent of transesophageal echocardiography but is invasive and does not allow to detect extracardiac RLS. Contrast transcranial Doppler ultrasound enables the detection of the passage of a contrast material injected into a peripheral vein to the c...

Visual inspection of a dry adult human skull revealed absence of a typical foramen ovale on the left side of the cranial base. The region of the foramen ovale was covered by an osseous lamina, which was continuous with the lateral pterygoid plate and thus formed a wall of an apparent canal, which opened on the lateral side of the pterygoid process. This canal is referred to as an oval canal (ca...
