【摘要】：目的:以第3直支为供血动脉,了解该动脉与第1、2及第4、5直支有效动脉弓交通关系,获得以第3直支为蒂的空肠有效动脉弓长度及以该血供的空肠切取范围,为临床提供解剖依据。方法:1.解剖测量32具福尔马林固定尸体小肠(尸体小肠,下同)及21具新鲜尸体小肠(新鲜小肠,下同)的空肠动脉第1-5直支血管直径,有效动脉弓血管直径,有效动脉弓伸直长度并对血管数据进行统计学比较。 2.对上述新鲜小肠以空肠动脉第3直支为蒂分别灌注红色醋酸乙酯溶液及ABS血管铸型剂,获取以第3直支为供血动脉的有效动脉弓供血肠管的范围,获得以第3直支为蒂的可切取的空肠长度。结果:1 两组小肠血管变异在可接受范围内,测量数据可有普遍意义。 2.在空肠动脉第1-5直支中,第3直支管径较粗,可提供肠管充足的血液动力。 3.以第3直支为蒂的血供分布区域,肠壁血管吻合交通丰富;系膜直动脉粗大,直动脉之间有数量较多的血管吻合及交通,血液循环良好。 4.以第3直支为蒂灌注红色醋酸乙酯溶液后,均匀染色的肠管游离缘长度可达142.2±13.6cm,可以满足食管重建对移植肠管长度的要求。 5.以第3直支为蒂,ABS有效分布动脉弓的平均长度为30.8±1.6cm,可提供足够的有效动脉弓长度及该长度血供范围的空肠长度。结论:本解剖研究证明:空肠以第3直支为蒂作游离空肠移植,不仅有足够长度的有效血管弓而且有足够长度血供的肠管,满足临床作食管重建的需要。
[Abstract]:Objective: to understand the third supplied artery, the artery and the 1,2 and 4,5 ratio of effective traffic to obtain the relationship between arterial arch, third jejunal length of jejunal artery arch length and effective blood supply to the jejunum cut the scope, to provide anatomical basis for clinical.
Methods: 1. anatomical measurements of 32 cadavers (formalin fixed intestinal body of small intestine, the same below) and 21 fresh cadavers (fresh small intestine, the same below) the 1-5 straight jejunal artery vessel diameter, vessel diameter and effective arterial arch, effective arterial arch stretched length of vessel data were compared.
2. of the fresh cadavers to jejunal artery third jejunal length were perfused with red solution of ethyl acetate and ABS vascular cast agent to obtain third supplied effective arterial blood supply artery arch bowel, obtained in third supplied the jejunal length.
Results: 1 of the two groups, the variation in the small intestine vessels was acceptable, and the measured data could be of universal significance.
2. in section 1-5 straight jejunal artery, third straight pipe diameter is thick, can provide adequate bowel blood dynamics.
3. to third of the blood supply of the jejunal length distribution, intestinal anastomosis traffic rich; mesangial straight arteries, there is a large number of vascular anastomosis and direct traffic artery, blood circulation is good.
4. to third red blood supply of ethyl acetate solution, uniform staining intestinal free edge length was 142.2 + 13.6cm, can meet the requirements of the graft length of esophagus reconstruction.
5. to third jejunal length, average length of ABS distribution of aortic arch was 30.8 + 1.6cm, can provide enough effective arterial arch length and the length of the blood supply of the jejunal length range.
Conclusion: the anatomical study proved that jejunal length for jejunum with third free jejunal transplantation, not only effective vascular arch of sufficient length and enough length of the blood supply of the bowel, meet the clinical need for esophageal reconstruction.
