Study of Peripheral Arterial Disease and Cardiovascular Risks in Patients with Lower Limb Deep Vein Thrombosis Including Unprovoked, Provoked, and Cancer-Related Cases

What this Trial Is About

Researchers are studying the frequency of Peripheral Arterial Disease PAD and cardiovascular risk factors in patients with unprovoked Deep Vein Thrombosis DVT of the lower limbs. The study compares these patients with those having provoked DVT or cancer-related DVT. It also examines the relationship between the Ankle-Brachial Index ABI and Carotid Intima-Media Thickness IMT across these groups. This observational study is done at a single center with both retrospective and prospective designs, aiming to conclude by December 31, 2027. The study follows outpatients diagnosed with lower limb DVT who undergo ultrasound evaluations. Patients are grouped into unprovoked DVT, provoked DVT, and cancer-related DVT categories. PAD diagnosis includes measurements such as ABI and IMT, with specific criteria and classifications for these measures. The study gathers data through routine clinical evaluations, ultrasound, and Doppler exams, without any drug treatments or interventions involved. Participants attend the Vascular Day Service where their clinical history, ultrasound imaging, ABI, and IMT measurements are recorded. Researchers monitor the frequency of PAD, presence of atherosclerotic plaques, and the correlation between ABI, IMT, and DVT. Secondary outcomes include following thromboembolic recurrence and cardiovascular events during standard clinical care. The study includes adults diagnosed within the last six months and continues data collection until the studys end date.
