糖尿病足介入治疗的几个问题

糖尿病足的血管检查应以超声检查为首选,其次为CTA和MRA,最后为血管造影,DSA检查应视为金标准。糖尿病足病变主要由小动脉病变和微循环障碍引起,因此除局部血管成形,置放内支架外,局部药物灌注治疗极其重要。糖尿病是一个全身性疾病,糖尿病足的治疗不仅要注重血管腔内局部治疗,还应全身药物治疗,应用活血化瘀,改善微循环药物,包括糖尿病治疗。对糖尿病足疗效不只是评价血管狭窄与再狭窄,应该包括临床症状缓解情况,保肢和降低截肢平面等。

A rational recognition of interventional teatment for diabetic foot

According to program of vascular examination of diabetic foot, the first choice is vascular ultrasonography as the general survey, followed by CTA and MRA for assessment of bilateral lower extremities arterial morphological changes. Lastly, arterial angiography including DSA still remain as the gold standard for estimation. The main pathologic changes of diabetic foot including arteriolar and microvascular disorders induce the extemely important interventional treatment especially the local thrombolytic infusion to be the real practical management besides local PTA and stenting are furthermore in consideration. As a general metabolic disease, the serial treatment should also include promoting blood flow, removing blood stasis and improving microcirculation . Evaluation of interventional treatment for diabetic foot should undertake not only the vascular stenosis and restenosis ,but also the relief of clinical symptom and improvement of amputation level.
