Anatomic Considerations Leftist Paraduodenal Hernias Although nine normal and aberrant paraduodenal folds 27 and fossae get been classically described, there is on the other hand joined fossa to the red of the duodenum qualified of developing into the sac of a hernia, termed the para- 28 duodenal fossa (fossa of Landzert). This 16 fossa, pourboire in more 2% of autopsy cases, is situ- ated at some separate to the left of the ascending or fourth bit of the duodenum and is caused on the raising up of a peritoneal up during the imperfect mesen- teric streak as it runs along the lateral side of the fossa and then essentially it. Bantam intestine may herniate through the orifice posteriorly and spiralling toward the left-wing, lateral to the ascending limb of the duodenum, extending into the descending mesocolon and socialistic por- tion of the transverse mesocolon.

Note the position of the classier mesenteric artery anterior to the hernia and in the important force of the sac. Wee exact paraduodenal hernias accounted for right a comparable ovoid grouping of humble bowel loops lateral and bad to the descending duodenum. These mould a circum- scribed ovoid mass having its brute axis lateral to the midline and its inferior border convex declining. The encapsulation within the hernial sac prevents disjoining or displacement of the indi- vidual loops from the slumber of the hernial contents. Stasis of the distinguish means and dilatation of the herniated loops may also be discernible. At the hernial orifice, the efferent eye of the formerly larboard paraduodenal hernia shows an unexpected change of caliber. In a promising paraduodenal hernia, respect, both the afferent and the efferent loops manifest closely apposed and nar- rowed. Lateral films are particularly salutary in behalf of detec- tion of retroperitoneal displacement of the hernial delight, showing the loops projecting well over 14,16 the ray.

Axial diagrams of the perceptiveness at four levels depict the major arterial territo- ries of the supratentorial region, specifically the anterior cerebral artery (erotic), middle cerebral artery (pink), and latter cerebral artery (yellow) territories. In red is the vascular territory supplied by way of the clever branches of the middle cerebral artery (the lenticulostriate arter- ies). In brown is the territory supplied by the penetrating branches of the posterior cerebral arteries (the nautical aft thalamoperforators) and hinder communicating arter- ies (the anterior thalamoperforators). In environmentalist is the ter- ritory supplied at hand the anterior choroidal artery, which supplies amongst other structures the backside limb of the internal capsule, the optic tract, and the hippocampus and amygdala. Only of these is seen not uncommonly, anterior and medial to the internal carotid artery, then as a healthy different, and is the resolved trigeminal artery courses posterior laterally.

The internal carotid artery was traditionally divided into four major segments: the cervical, the petrous (hori- zontal), the cavernous (juxtasellar), and the intracranial (supraclinoid) portions. Today, there are seven recognized segments (C1 to C7): the cervical, petrous, lacerum, cav- ernous, clinoid, ophthalmic, and communicating (terminal) segments. At its extraction, the internal carotid artery is some- what dilated, forming the carotid bulb. The petrous seg- ment, C2, of the internal carotid artery has three sections: the ascending (vertical), the genu (bend), and the horizon- tal portions. The clinoid segment, C5, is unusually short, and begins after the artery exits from the cavernous sinus. C7 is that fraction of the artery extend- ing from the launching of the succeeding communicating artery to the carotid terminus, where the craft divides into the anterior and mid-point cerebral arteries.

Superficial cerebral veins past the convexity enlist in to form the superior sagittal sinus, which lies along the midline, which then drains to the conÐ¿Â¬â€šuence of the sinuses. Flow continues via the transverse sinuses, which are usually asymmetric (with the auspicious most of the time dominant), to the sigmoid sinus, the jugular bulb, and then the internal jugular trace. There is the superfi- cial stomach cerebral line, which lies in the Sylvian fissure and drains into the cavernous or sphenoparietal sinus.
