Vascular Anatomic Variation in Rabbits

Journal of Vascular and Interventional Radiology, 2006
To explore the vascular anatomic variation along the aortic arch in New Zealand White rabbits with the goal of highlighting potential anatomic configurations that might be encountered in the performance of preclinical endovascular research in rabbits.Digital subtraction angiography images of the brachiocephalic artery (BCA) and aortic arch in New ...

Anatomical Variation Of The Sphenomandibular Ligament

Australian Endodontic Journal, 2001
ABSTRACTThe sphenomandibular ligament, which is derived from the sheath of Meckel's cartilage, is a fibrous structure that passes between the spine of the sphenoid bone and the lingula of the mandible. Although anatomical texts provide basic descriptions of this structure, there are few published reports of the extent of its variability or its possible

Pancreatic Development and Anatomical Variation

Gastrointestinal Endoscopy Clinics of North America, 1995
The pancreas is formed by the fusion of the ventral and dorsal anlage, and a wide spectrum of anomalies or anatomical variations may appear related to this complicated process of fusion: e.g., agenesis, aplasia of a pancreatic anlage, hypoplasia, annular pancreas, pancreas divisum or nonfusion of the ventral and dorsal duct system, pancreaticobiliary ...

Anatomical Variations of the Cystic Artery

European Journal of Morphology, 2003
Thorough knowledge about the origin of the cystic artery is surgically important, especially when intraoperative or post-operative bleeding occurs in the gallbladder fossa. The arterial supply of the gallbladder was studied in 81 livers. The gallbladder was supplied by one cystic artery in 86% and by two arteries in 14% of cases.

Anatomical Variations of Nasal Turbinates

Journal of Craniofacial Surgery, 2008
After the widespread use of endoscopic sinus surgery and paranasal sinus computed tomography, many variations of nasal turbinates have been described. In addition to the most common one-middle turbinate pneumatization (concha bullosa)-superior and inferior turbinate pneumatizations have also been described.

Anatomic Variations of the Frontal Sinus

min - Minimally Invasive Neurosurgery, 2003
Minimally invasive approaches are increasing in popularity. We have undertaken an anatomic and radiological study of the frontal sinus that is frequently involved in the supercilliary minicraniotomy used to access the parasellar region.We wanted to evaluate the prevalence and morphological characteristics of the frontal sinus in a certain population ...

Anatomic Variation of Sphenoid Sinus and Related Structures in Libyan Population: CT Scan Study

Libyan Journal of Medicine, 2008
Background: Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate

Anatomic Variations of the Nasolabial Fold

Plastic and Reconstructive Surgery, 1992
The nasolabial fold varies considerably from person to person. Three main groups may be distinguished: convex, concave, and straight. It is the muscles of smiling that are directly responsible for the shape and depth of the fold, and in their absence of function, as in facial palsy, the nasolabial fold disappears.

Anatomic variations in the tetralogy of Fallot

American Heart Journal, 1971
Abstract Eighty-five specimens with a tetralogy of Fallot from patients varying in age from infancy to adult life were studied for (1) the nature of the pulmonary valve, the right ventricular infundibulum, the pulmonary arteries, the aortic arch, and the atrial septum and (2) the association of other anomalies and of bacterial endocarditis.

Anatomic variations and stone formation

Current Opinion in Urology, 2018
The pathophysiological mechanisms in kidney stone formation are insufficiently understood. In order to achieve a better understanding of the complexity of stone formation, studies evaluating anatomical variations in the renal papillae have been performed. This review intends to illuminate recent findings.
