CHRONIC LIMB ISCHEMIA

Abstract

Background: The Ankle brachial index (ABI) measurements are commonlyused inscreening and management of Peripheral Vascular Disease. In recent studies, Anklebrachial index (ABI) is utilized as a predictor of future atherosclerotic vascular disease andall-cause mortality. Purpose: The purpose of this study was to investigate utility of pre andpost peripheral vascular intervention ankle-brachial index (ABI) assessmentinpatientswith thechronic limb ischemia. Study Design: Quasi experimental study. Setting: National Instituteof Cardio-Vascular Disease (NICVD), Karachi, Pakistan. Period: January 2013 to June 2014.Methodology: The study included 23 patients hospitalized. According to study inclusion/exclusion criteria, patients of chronic limb ischemia on clinical ground and the vascular lesionsof lower limb according toTrans-Atlantic Inter-Society Consensus (TASC scoreclassification II)were evaluated and recruited. The lesions were further classified into three types, Aortoilliac,Femoropopliteal andTibioperoneal. Ankle brachial index (ABI) was classified according toAmerican Diabetic Association. The study was approved by the ethical committee of NICVD.Data was analyzed using SPSS 20. Inc. Results: The mean age of the enrolled patients was57.86±6.56 years. Majority of the patients were male 18(78.3%). The commonly found peripherallesion was femoropopliteal in 9(39%), TASC grade A was commonwith 8 (62%) of cases. ABIscore done pre and post procedure showed a significant difference with a (p-value<0.05) andthere was an improvement of ABI scores in all the lesions after peripheral vascular intervention.Conclusion: The study results concluded that there was animprovement in ABI score afterintervention of peripheral vascular surgery for lower limb segment and recommended its utilityfor the assessment in Peripheral Vascular Disease intervention.
