The Study On Bilateral Deep Artery Anastomosis Branch Of The Tongue In Fetus

Objective The purpose of the study was to observe the bilateral lingualartery anastomosis and following the unilateral ligation of lingual artery of theblood supply to the tongue, and provide anatomic basis for the the bloodsupply to the tongue and the flap design when the lingual artery can not bepreserved.Material and methods To collect fresh fetal (more than five and a halfmonths) the corpse specimen20. In the bilateral carotid triangle dissection ofinternal carotid artery, external carotid artery, internal jugular vein and leftsubclavian artery, the aortic archto was dissected and exposed in the areabefore the heart. A catheter was inserted into the the aortic archto, with theinternal carotid artery ligated and internal jugular vein opened. Within thePirogoff triangle showed and ligated one side of the lingual arteries; Thenrandom experiment using one of the following methods:(1) Experiment oflead oxide X-ray angiography. After one side of the lingual artery was ligated,then, aortic arch angiography in3cases;2cases without ligation of lingualartery in aortic arch angiography;(2) Indian ink perfusion and histologicalobservation the blood supply of the tongue in15cases, of which one side afterligation of lingual artery perfusion of Indian ink transparent sections of11cases without ligation of lingual artery; Ink perfusion system made the abovesection in4cases.Results1Lead oxide angiography X-ray observation: lead oxide withoutligation of lingual artery angiography shows deep lingual arteries andsublingual arteries and its branches within filled with contrast medium, in thetip of the tongue area deep lingual arterybranches and the root of the tonguefor anastomosis between the tongue, and filled with contrast agents, in themiddle of the tongue, between the bilateral deep lingual artery have anastomosis branches, and visible contrast filling. Lingual artery angiographyshowed no ligation after ligation side side deep lingual arteries, and sublingualarteries and its branches in contrast filling; Tongue deep inside the arteryligation side contrast filling defect, but the tongue deep artery supply areavisible image contrast filling, visible and the contralateral side of the tip of thetongue of ligation of lingual deep artery anastomosis contrast filling inside,but bilateral lingual septum area fits within the contrast filling is rare.2Prepared Indian ink perfusion specimens of gross and histological observation:without ligation of lingual arteries tongue deep inside the artery and itsbranches are filled with ink, submucosal arterial blood within the networklayer and mucosa capillary plexus are filled with ink; After artery ligation onone side of the tongue, tongue muscle tongue deep inside arteries and malesthat are notneutered branch pipe wall lining layer is prepared Indian inkdyeing, intramuscular vascular ligation side tongue prepared Indian ink dyeingsparse, submucosal arterial blood pipe network and mucosal capillary plexuswith prepared Indian ink dyeing, but less ligation side decreases. Lingualseptum in small blood vessels through or with intramuscular vessels exist onboth sides of the tongue (ligation of artery or lingual artery ligation) on oneside of the tongue.Conclusion After ligating one side of the lingual artery, the side of the bodyof the tongue can be through the way of the floor of the mouth directly fromthe submental artery or other external maxillary artery branch blood supplycan be obtained, from contralateral deep lingual artery anastomosis obtainblood supply, its levels are submucosal arterial network, in tongue veinnetwork, bilateral deep lingual artery except the tip is consistent, there areanastomoses lingual septum. Therefore, on one side of the lingual artery is notpreserved in the case, after partial glossectomy residual tongue exceptpathway from the floor of the mouth of the submental artery or externalmaxillary artery branch obtain blood supply, can be obtained from thecontralateral lingual artery blood supply; and that, on one side of the lingualartery cannot be preserved in the case of tongue flap whether the application for flap design varied with different types, such as the floor of the mouthtissue defect too much, can not use.
