Exempel på fossa

• The post-temporal fossa is small and directed anteromedially.

• However, the homology between the dinosaurian structure and the mammalian fossa subarcuata is doubtful.

• Subjects with interatrial communication: 55 patients with an interatrial communication were studied (48 within the oval fossa; 7 of sinusvenosus type).

• There was a 5 mm atrial defect in the oval fossa with left to right flow noted.

• Echocardiography showed normal chamber and vessel relationships, a small patent arterial duct, and an atrial septal defect with bidirectional shunting across the oval fossa.

• There was a right-to-left shunt through an atrial septal defect within the oval fossa and a left-to-right shunt through a patent arterial duct.

• Our case had a large perimembranous ventricular septal defect, an atrial septal defect within the oval fossa, and pulmonary valvar stenosis.

• When considering the technical aspects of percutaneous closure of defects within the oval fossa, we should not forget the natural history of this malformation.

• Note the location and relationships of the oval fossa.

• Only one patient had a sinus venosus defect in addition to the defect within the oval fossa.

• The echocardiogram demonstrated an atrial septal defect within the oval fossa and normal contractility.

• Morphological variations of fossa ovalis atrial septal defects (secundum): feasibility for transcutaneous closure with the clam-shell device.

• The adductor fossa and the anterior and posterior meckelian foramina are also partially filled with matrix.

• Detailed anatomical examination of the oval fossa and its environs relative to placement of the device is obviously of great practical importance.

• The adductor fossa is considerably wider (20 mm) than in equivalent-sized mastodonsaurid mandibles, and measures 115 mm in length.
