Lower Extremity Arterial Disease

Introduction: Peripheral arterial disease is a condition due to partial or complete occlusion of arteries excluding that of heart and brain. Lower extremity arterial disease is specific to lower limbs. Some of the patients are asymptomatic while a majority present with claudication, rest pain, ulceration or even gangrene. Methods: We took all admitted cases of lower extremity arterial disease from January, 2015 to December 2018. ABI was used as the first clinical tool for the diagnosis of PAD in patients with history or physical examination findings suggestive of PAD as per AHA guidelines. Outpatient arterial Doppler ultrasonography complemented by lower limb CT angiogram was used as a confirmatory tool for the diagnosis and also to assess anatomical location and severity of stenosis. Results: Total of 54 cases of lower extremity arterial diseases were identified with a mean age of 59.2 years (S.D. 11.4). Right lower limb was involved in 35(50%). Mean age was 58 years(SD 13.1). Mean duration of symptom was 3.4 years (SD 3.3). Claudication was present in all the patients. 32(45.7%) had ulcers. Toe(44.3%) was most commonly involved. Decreased local temperature(91.4%) and color change(87.1%) were major symptoms. 35(50%) of the patients had gangrene. Mean peak systolic velocity was lowest in the peroneal artery. 16.6% patients got additional peripheral bypass surgery. Conclusion: Claudication, decreased local temperature and color change were very common findings of lower extremity arterial disease. Gangrene was present in half of the patients.

Abstract Introduction Ankle-brachial pressure indices (ABIs) continue to form the basis of diagnostics for lower extremity arterial disease (LEAD). However, there remains a paucity of data to support its accuracy. This study aims to evaluate its diagnostic sensitivity and specificity using established arterial-imaging modalities as a benchmark. Methods In this retrospective study, a regional, prospectively maintained, vascular laboratory database was interrogated to identify referred patients with arterial disease who underwent concomitant assessment with ABI and lower limb arterial duplex ultrasound (DUS). Duplex acted as the reference standard. Those who had peripheral computed tomography angiogram (CTA) within 3 months of initial assessment were included in a subgroup analysis to correlate ABI with CTA. The primary end point was the sensitivity and specificity of ABI compared with DUS as the reference standard. Results Concomitant assessment was performed in 438 limbs (250 patients) over a 27-month period. The ABI was normal (0.9 to 1.4) in 196 limbs (44.9%) and abnormal in the remaining 241 limbs (55.1%). False-positive results occurred in 83 out of 241 limbs (34.4%), and false-negative results occurred in 54 limbs out of 196 (27.5%). True-positive results were 158 out of 241 limbs (65.6%), whereas true-negative results were 142 out of 196 limbs (72.4%). ABI using DUS as a benchmark identified a sensitivity for peripheral artery disease of 72.3% and a specificity of 69.3%. Concomitant CTA imaging was available in 200 limbs. The sensitivity and specificity of ABI correlated with CTA were 65.5 and 68.8%, respectively. Conclusion ABIs have a moderate predictive value in the diagnosis of LEAD. Normal range outcomes cannot be taken to infer the absence of LEAD and, as such, further arterial imaging in the form of DUS or angiography should be strongly considered in those with suspected underlying disease requiring intervention. Further noninvasive tests such as exercise studies or pulse volume waveforms should be considered, if diagnostic uncertainty exists, in those requiring nonoperative intervention and risk factor control.
