The aim of study was to assess the usefulness of non-invasive imaging in patient of diabetic foot ulcer with low field MRA and determine the severity and extent of lower extremity arterial disease in diabetic patients with poor socio economic status. The present study is based on 38 patients who were referred to Department of Radiology with complaint of non-healing ulcer of lower limb of more than 6 weeks duration. The patients were subjected to plain radiographs, Duplex scanning with color flow imaging and MR angiography (non contrast enhanced). The modalities were used to detect vascular calcifications, osteomyelitis, bone resorption, deformities, thickening of arteries, plaques, spectral waveforms, collaterals. MRA was used to assess subjective calibre of vessels and presence of stenosis. The patients were categorised according to age and a note of ulcer duration made. Grade of ulcer was determined (wagner’s criteria) and note was made of severity of stenosis (cossman). Radiographs assessed bony destruction and vascular calcification. Doppler assessed degree of stenosis and vascularity. MRI gave a road map of vascular integrity. Integration of the tests provided a satisfactory diagnostic protocol to decide future prognosis and assessment of advancement of disease process. The data was subjected to calculation of mean, standard deviation and Pearson’s chi square test. p value?<?0.05 was considered to be stastically significant. Majority of patients were males (80%) and highest incidence was noted in fourth-fifth decade (43.33%). 47.37% presented with grade III ulcer. Duplex scanning with color flow imaging was more accurate and sensitive in picking up calcified arteries, focal plaques, stenosed arteries and abnormal arterial waveforms. These patients had co-existent lower extremity arterial disease with moderate to severe stenosis (i.e. on comparision with peak systolic velocity (PSV), p?<?0.05. Ulcer grade had stastically significant correlation with severity of stenosis, (p?<?0.05). However MRA did not corroborate the same findings. It proved to be only 60% sensitive when compared to Duplex scanning (100%). Plain radiographs and color Doppler evaluation plays an indispensable role in imaging and evaluating patients with chronic non-healing ulcer of diabetic foot. MRA gives crucial information regarding parameters like vascularity, degree of stenosis, and extent of disease. Not all patients in our set up afford CTA or CEMRA followed by DSA or cost of stenting. When the diagnostic workup in our cases suggested poor prognosis or non salvageable vascular compromise the patient was counseled against further investigation and advised surgery. By using this approach many financially constrained patients are benefitted from unnecessary and costly diagnostic workup. 相似文献

Diabetic foot is a serious complication of diabetes mellitus and the risk of lower extremity amputation is very high in this population when compared with people without diabetes. We have previously reported the lower-extremity amputation rate and significant factors in determining the risks for patients who had been admitted to Hacettepe University Hospital, a tertiary reference center for Turkey, between the years 1992 and 1996. In January 2000, a diabetic foot care team including an infectious diseases specialist, orthopaedic surgeons, endocrinologists, a plastic and reconstructive surgeon, a radiologist, and a diabetic foot nurse was assembled. To determine whether a change has occurred in the rate and the risk factors of lower extremity amputations after the establishment of this team, medical records of 66 patients (39 men, 27 women) with diabetic foot who had been admitted to Hacettepe University Hospital between 2000 and 2002 have now been retrospectively analysed. The grade distribution of diabetic foot according to Wagner classification was quite similar in the two studies (grade 1: 0 % vs. 4.5 %, grade 2: 15.6 % vs. 19.7 %, grade 3: 48 % vs. 33.3 %, grade 4: 24.4 % vs. 30.3 %, grade 5: 11.5 % vs. 12.1 % in the former and current study, respectively). The overall amputation rate in the current study was 39.4 % (36.7 % in the former study). Ray amputation (35 %) and below-knee amputations (30 %) were the two most commonly applied procedures. The rates of Syme, above knee, other amputations (i.e., Boyd, talonavicular amputations and partial calcanectomy) were 8 %, 8 % and 19 %, respectively. These data suggest that amputation is still a frequently encountered outcome for our patients with diabetic foot, but the amputation profile has changed. The implementation of a diabetic foot care team has relatively decreased the rate of major amputations in an attempt for limb salvage to improve the quality of life of the patients. Presence of osteomyelitis, peripheral vascular disease and gangrene still remain as significant predictors of amputation in our population. 相似文献

Diabetic foot disease causes important morbidity in diabetic population, and amputation due to diabetic foot disease occurs more often than in general population. We have been evaluating patients with diabetic foot disease in a multidisciplinary approach since year 2000. In the current study, we sought to investigate the change in amputation rate and its predictors in diabetic foot with a multidisciplinary team approach. Seventy-four patients (52 male, 22 female) hospitalised between January 2002 and December 2007 were retrospectively analysed. Sixteen out of 74 have undergone amputation. We found overall amputation rate as 21.6%, which is lower than previously reported from our institution (36.7 and 39.4%, respectively). Major amputations (syme, below-knee, above-knee) were applied to 11 patients (14.9%). A logistic regression model including osteomyelitis, peripheral neuropathy, peripheral vascular disease, hypertension, gangrene and age revealed that gangrene is now the only significant predictor for amputation. Our observations confirm that amputation rate has declined after implementation of a multidisciplinary team work, and risk factors apart from presence of gangrene are no longer amputation predictors in our centre. 相似文献

目的探讨确诊2型糖尿病伴发下肢动脉硬化闭塞症的检查方法.方法主诉下肢或足部麻木或疼痛、溃疡、坏疽的2型糖尿病患者中,经下肢动脉节段性测压(踝/肱指数ABI)或彩色超声检查发现有下肢动脉缺血征象者,进一步作磁共振血管显像(MRA)、螺旋CT血管显像(SCTA)或数控动脉造影检查(DSA)以明确诊断.结果43例患者经ABI测定诊断为2型糖尿病合并下肢动脉硬化闭塞症,ABI在0.00~0.68范围,平均0.36.全组患者均作了MRA或SCTA,DSA检查,ABI无一例假阳性,最后确定43例中5例为主髂动脉段闭塞;19例为股腘动脉段闭塞;11例为股腘动脉伴腘动脉1~2分支闭塞;8例为膝以下动脉闭塞.43例根据造影结果分别接受了不同的手术或(和)药物治疗.结论节段性测压和彩超检查是初步诊断下肢动脉硬化闭塞症的无创检查方法,它的特点是简易、价廉、无损伤性、患者易接受;MRA,SCTA也属无损伤性检查,对确定动脉闭塞的部位、程度和范围均十分有益,最精确的检查还是插管动脉造影. 相似文献
