Background: Diabetic foot complications remain a significant concern in healthcare, often compounded by the presence of peripheral vascular disease (PVD). Understanding the prevalence of PVD in patients with diabetic foot is crucial for effective management and prevention of associated complications. This study investigates the prevalence of PVD using ankle-brachial index (ABI) and Arterial Doppler in a cohort of patients with diabetic foot. Objective: The primary aim of this observational study is to assess the prevalence of PVD in patients with diabetic foot through the measurement of ABI and Arterial Doppler. The study further aims to identify associations between PVD prevalence, patient demographics, and diabetes-related factors. Methods: Conducted at the Department of General Surgery, National Institute of Medical Sciences and Research, Jaipur, this single-institution study spanned from July 1, 2022, to July 31, 2023. The study included 95 patients meeting inclusion criteria, encompassing those with type-2 diabetes mellitus and diabetic foot who provided informed consent for participation. Patients willing to undergo or those who had undergone Arterial Doppler study of the lower limb were included. Detailed history, clinical examinations, ABI measurements, and additional investigations, including HbA1C and Arterial Doppler of the lower limb, were conducted after obtaining informed consent. Results: Ninety-five patients admitted to NIMS Hospital, Jaipur, with diabetic foot were included in the analysis. The study revealed a notable prevalence of PVD, with 47.3% of patients affected. Age ranged from 41 to 78 years, with a mean average of 52.0+7.2 years and a male to female ratio of 3.75:1. Significant associations were observed between the duration of diabetes, severity of PVD, and age. Advanced age and poorly controlled diabetes emerged as notable risk factors for PVD. Conclusion: This study contributes valuable insights into the prevalence of PVD in patients with diabetic foot. The observed prevalence of 47.3% underscores the importance of vigilance in this population. The study recommends the use of ABI as a screening tool for early detection and risk stratification based on disease severity. Additionally, the integration of Arterial Doppler alongside clinical methods proves essential for a comprehensive evaluation and the subsequent management of diabetic individuals with peripheral vascular disease.
