Abstract:
Objective To evaluate the clinical value of the upper extremital artery supply and vein running back in the patients after peripheral vascular surgery by Na99mTcO4 trace imaging(TTI).Methods SPECT static imaging was performed on 36 patients after peripheral vascular surgery in vein injecting Na99mTcO4 740 MBq 5min.The radioactivity uptake of operated limb(finger)/normal limb(finger) ratio(T/NT) was analyzed using region of interest analysis.0,Ⅰ,Ⅱand Ⅲ scales were classified according to their radionuclide distribution and T/NT,were divided into A,B,C and D group,respectively.Localy warming and anticontrctive therapy were only given in A and B group for 30min,routine therapy in C group,and raising operated limb (finger) and reductive pressure treatment in D group.Then,exploratory surgery was performed on 0 scales and Ⅲ scales of TTI again.Results A,B,C and D group were 11,7,13 and 5 patients,their T/NT was (0.142 ± 0.058),(0.384 ± 0.046),(0.794 ± 0.072) and (1.12 ±0.076),respectvely,and there were significant differences among the groups(t =2.33a,4.33b,6.90b,2.59a,5.73b,2.12a,aP ＜ 0.05,b P ＜ 0.O1) ;TTI again showed:there were 7 cases of 0 scales (arterial thrombosis was confirmed by exploratory surgery) and 4 cases of Ⅰ scales in A group,3 cases of Ⅰ scales and 4 cases of Ⅱ scales in B group,all 13 cases of Ⅱ scales in C group,4 cases of Ⅱ scales and 1 case of Ⅲ scales(vein thrombosis was confirmed by exploratory surgery) in D group.Conclusion TTI could play an important role in economical,simple and notraumatic diagnosing the extremital artery supply and vein running back in the patients after peripheral vascular surgery.
