Comparable Study Of Deep Balloon Dilation And Balloon Dilation Combined With Stent Placement In Treating Arterial Sclerosis Obstruction (aso) Of Superficial Femoral Artery (sfa)

OBJECTIVE:38 patients were included in this study who were treated by intraluminal therapy. They were treated by Deep balloon dilation and balloon dilation combined with stent placement, respectively. We aimed to evaluate the results of these two methods thus determining which one has better clinical outcomes and is perferential in treating this kind of disease.METHODS : We choose 38 cases who were treated in surgery department of Bethune Internation Peace Hospital from March, 2008 to March, 2009. These patients were divided into two groups : treatment group and comparison group. The lengths of the stenotic segments were between 5-10cm. Among the patients , 23 were males and 15 were females. Their ages ranged from 49 to 78 years old , with the meaning age being 61.7. For the 19 patients in treating group, we uesd Deep balloon to dilate the stenosis or occlusion of SFA. Among them, 8 patients also had stenosis or occlusion of common and external iliac artery and 6 cases also had stenosis or occlusion of popliteal artery. For the 19 patients in comparison group, we performed balloon dilation combined with stent placement(balloon 6*40mm,stent dimeter is 6mm).Among them, 7 patients also had stenosis or occlusion of common and external iliac artery and 6 cases also had stenosis or occlusion of popliteal artery. For the patients who also had lesion in common iliac, external iliac and popliteal artery, we treated all the lesions at the same time. The puncture sites included contralateral femoral artery, ipsilateral femoral artery and left brachial artery. All the data obtained at follow up were statisticallly analysed.RESULTS:We analysed the gender withχ2 test and analysed the age with t test. The results showed that p>0.05 which indicated there is no significant difference in sexual and age between the two groups. It also indicated the two groups were comparale in sex and age. The instant patent rates were 100% in both groups. At 1 month follow up, the patent rates were 100% in treating group and 95% in comparison group. At 1 year follow up, the patent rates were 85% and 74% , respectively. Analysing the ABI (ankle brachial index) in two groups with test。Instant results: P=0.504, P>0.05,there is no difference between the two groups. At 1 month follow up, P is 0.024(<0.05) which showed significant difference between the two groups. At 1 year follow up, the P is 0.002 ( P<0.01) from which we can see remarkable difference.CONCLUSION:From our study it can be concluded that the patent rate in treating group at 1 month and 1 year follow up is higher than that in comparison group. The main mechanism is Deep balloon has better flexibility, smalle section which produce less injury on vessel.
