Peripheral artery disease affects an estimated 6.5 million adults in the United States aged 40 and older, yet it remains one of the most underdiagnosed cardiovascular conditions in everyday clinical practice. Defined by the progressive narrowing of arteries—primarily in the legs—due to atherosclerotic plaque accumulation, PAD restricts blood flow to the limbs, significantly elevates the risk of heart attack and stroke, and in advanced cases can threaten limb viability. Many patients never seek evaluation because they attribute their symptoms to ordinary aging or musculoskeletal wear rather than arterial disease.
Griffin Faculty Physicians, a non-profit multi-specialty medical group affiliated with Griffin Hospital in Derby, Connecticut, takes a structured, prevention-centered approach to managing peripheral artery disease and supporting long-term vascular health. Through a dedicated vascular medicine program, Griffin Faculty Physicians brings together diagnostic precision, evidence-based medical management, and minimally invasive procedural capabilities to serve patients across the Lower Naugatuck Valley and surrounding communities in Connecticut.
Understanding Peripheral Artery Disease and Its Systemic Significance
Peripheral artery disease develops when fatty plaques accumulate along the inner walls of arteries, reducing the diameter through which blood can flow. In the lower extremities, this reduced circulation most commonly produces intermittent claudication—cramping pain, aching, or heaviness in the legs that occurs during physical activity and is relieved by rest. It sounds manageable. In reality, it signals something far more serious.
PAD is widely recognized by vascular specialists as a systemic marker of atherosclerotic cardiovascular disease. Patients with confirmed PAD carry a substantially elevated risk of myocardial infarction and ischemic stroke, independent of whether they experience leg symptoms at all. In its most advanced form—critical limb ischemia—insufficient blood flow produces rest pain, non-healing wounds, and eventually tissue necrosis. Without timely revascularization, limb amputation becomes a real possibility.
The condition disproportionately affects older adults, people with type 2 diabetes, long-term smokers, and individuals with poorly controlled hypertension or hyperlipidemia. Because many patients with mild to moderate PAD are either asymptomatic or mistake their discomfort for joint problems, a significant share of cases go undetected until the disease has advanced meaningfully.
The Griffin Faculty Physicians Approach to PAD Evaluation and Management
Griffin Faculty Physicians organizes its vascular medicine services around a clear clinical philosophy: prevention, monitoring, and long-term care. Rather than treating vascular conditions as isolated episodes that resolve after a single intervention, the practice takes a longitudinal view of each patient’s arterial health—identifying risk early, confirming diagnoses through objective testing, and then crafting individualized management plans that evolve as the disease does.
This philosophy matters for PAD specifically because the condition can remain relatively stable for years before accelerating sharply in response to an uncontrolled risk factor—a return to smoking, poorly managed blood sugar, or unaddressed hypertension. Monitoring without intervention creates a meaningful safety net; intervention without monitoring leaves undetected recurrence unaddressed.
Diagnostic Evaluation and Objective Risk Stratification
Diagnosis begins with a thorough history and physical examination, including assessment of pulses in the legs and feet. The centerpiece objective test is the ankle-brachial index (ABI), a non-invasive measurement that compares systolic blood pressure at the ankle to systolic blood pressure at the arm. An ABI below 0.9 is generally considered abnormal and consistent with significant arterial obstruction. Values below 0.4 indicate severe disease. Beyond its diagnostic utility, the ABI carries independent prognostic value—lower readings correlate with higher rates of cardiovascular events, making it a useful tool for systemic risk stratification as well.
Depending on clinical findings, vascular evaluation may also include duplex ultrasound imaging to visualize arterial anatomy and blood flow dynamics. Patients being assessed for procedural intervention may require computed tomographic angiography (CTA) or magnetic resonance angiography (MRA) to map the arterial tree in detail. The specific diagnostic pathway is individualized because the information needed differs considerably between confirming an early diagnosis and planning a complex revascularization.
Risk stratification guides all subsequent treatment decisions. Patients with mildly abnormal hemodynamics and minimal functional limitation may be managed conservatively through lifestyle modification and pharmacotherapy, while those with severe blood flow impairment or active tissue loss require more urgent evaluation for procedural intervention.
The Spectrum of Vascular Services Offered by Griffin Faculty Physicians
The practice’s vascular medicine program covers a broad clinical range, from non-invasive evaluation through to complex wound management and endovascular procedures. The table below summarizes the main service categories and their clinical scope.
| Service Category | Clinical Scope |
|---|---|
| Vascular Disease Evaluation and Management | PAD, carotid artery disease, aneurysm evaluation; prevention and long-term monitoring |
| Minimally Invasive Vascular Procedures | Peripheral angioplasty, arterial stenting, endovascular interventions to restore blood flow |
| Venous Disease and Blood Clot Care | Venous insufficiency, deep vein thrombosis, pulmonary thromboembolism, varicose vein treatment, venous ulcers |
| Complex Wound Care | Debridement, biological grafting, management of non-healing vascular wounds |
| Vascular Access and Device Management | Catheter placement, ongoing device monitoring and maintenance |
This range allows Griffin Faculty Physicians to care for patients across the full spectrum of vascular disease severity—from those with early-stage PAD who benefit most from risk factor counseling and medical management, to those with advanced disease who require procedural intervention, specialized wound care, or both in combination.
Minimally Invasive Interventions for Advancing PAD
When lifestyle modification and medication are no longer sufficient to manage PAD symptoms or prevent further deterioration, Griffin Faculty Physicians provides peripheral endovascular interventions—catheter-based procedures designed to restore arterial blood flow without the risks and recovery burden of open surgery.
Angioplasty is performed by threading a thin catheter tipped with a small balloon into the narrowed artery, then inflating the balloon to compress the plaque against the vessel wall and widen the lumen. Stenting extends this approach by deploying a small metal scaffold within the treated segment to keep it open after the balloon is removed. Both procedures are typically performed through a small access point at the groin or arm and carry significantly shorter recovery times than traditional bypass surgery.
Endovascular techniques have substantially changed the management of peripheral artery disease over the past two decades, making it possible to treat patients who are not candidates for open surgery due to age or comorbidities. In patients with critical limb ischemia, prompt revascularization is often the determining factor in whether a limb can be salvaged—making timing and close procedural follow-up as important as the technique itself.
Complex Wound Care in the Context of Advanced Arterial Disease
One of the most consequential—and sometimes underappreciated—dimensions of advanced PAD care is wound management. When arterial perfusion is severely compromised, even minor skin injuries can fail to heal, evolving into chronic ulcerations that become infected and, if left unaddressed, lead to tissue necrosis. This problem is especially common in patients with concurrent diabetes, whose peripheral neuropathy may mask early warning signs until wounds are already substantial.
Griffin Faculty Physicians addresses this through comprehensive wound care services focused on complex cases that exceed standard dressing protocols. Debridement—the removal of necrotic and non-viable tissue—creates a more favorable wound environment and is often the necessary first step before regenerative therapies take effect. Biological grafting then uses tissue-derived materials to stimulate closure in patients where the normal healing cascade has stalled.
Critically, wound care cannot be separated from the arterial problem driving it. Attempting to heal an ischemic wound without restoring adequate blood flow is rarely successful; at the same time, restoring perfusion without managing the local wound environment can lead to stalled recovery. The integrated approach to vascular wound care practiced within this program reflects that clinical reality directly.
Venous Disease: The Often-Overlooked Other Half of Vascular Health
While PAD centers on arterial insufficiency, the venous system presents its own chronic conditions that significantly affect quality of life. Griffin Faculty Physicians provides structured care for venous disease alongside its arterial services, recognizing that many patients present with coexisting conditions on both sides of the vascular equation.
Venous insufficiency occurs when the valves inside the leg veins fail to close properly, allowing blood to pool in the lower extremities rather than return efficiently to the heart. Over time, this produces leg swelling, heaviness, skin discoloration, and in advanced cases, venous stasis ulcers—chronic, difficult-to-heal wounds that respond poorly to treatment until the underlying venous pathology is addressed.
Venous care within the practice encompasses the following areas:
- Evaluation and treatment of venous insufficiency, including minimally invasive outpatient procedures for spider and varicose veins
- Management of deep vein thrombosis (DVT), including anticoagulation therapy and monitoring for complications such as post-thrombotic syndrome
- Management of pulmonary thromboembolism arising from clots that travel from the leg veins to the lungs
- Deep venous interrogation to assess the structural and functional integrity of the venous system
- Treatment of venous stasis ulcers through specialized wound care in coordination with venous disease management
Patients presenting with leg swelling, chronic skin changes, or a history of blood clots benefit from systematic evaluation rather than isolated symptom treatment—an approach that reflects the comprehensive nature of vascular medicine at this level of specialization.
Long-Term Monitoring: Why Sustained Vascular Care Matters
Peripheral artery disease does not resolve following a single treatment. The underlying atherosclerotic process continues after intervention, and restenosis—the re-narrowing of a treated segment—can develop over months to years. Disease may also progress in previously unaffected arterial regions. This biological reality makes long-term follow-up not a formality but a clinical necessity for every patient with confirmed PAD.
Griffin Faculty Physicians builds sustained monitoring into the structure of its PAD management program as a matter of routine. Follow-up includes periodic reassessment of the ABI to detect hemodynamic changes, imaging surveillance for patients who have undergone endovascular procedures, and systematic attention to cardiovascular risk factors including blood pressure, lipid levels, blood glucose, and tobacco use. The aim is early detection of progression—identifying signals that warrant intervention before symptoms have deteriorated significantly.
Long-term outcomes in PAD also depend heavily on patient behavior between visits. Supervised exercise therapy carries strong evidence for improving walking distance and functional capacity in patients with intermittent claudication. Smoking cessation remains the single most impactful modifiable risk factor—continued tobacco use accelerates peripheral atherosclerosis more aggressively than virtually any other behavioral variable. Antiplatelet agents and statins complement these measures by reducing systemic cardiovascular event rates over time.
Clinical Expertise and Academic Foundations
The vascular medicine program at Griffin Faculty Physicians is led by Michael A. Sergi, MS, MD, FACS, a board-certified vascular surgeon who has been in practice since 2009. Dr. Sergi completed his surgical residency at St. Vincent’s Hospital in Manhattan and his vascular surgery fellowship at Yale-New Haven Hospital—one of the foremost academic medical centers in the northeastern United States. He brings more than two decades of experience to the care of patients managing chronic and complex vascular disease.
Beyond clinical practice, Dr. Sergi has contributed peer-reviewed research to the vascular surgery literature, grounding his work in ongoing scholarly engagement. He also serves as a faculty member at the Frank H. Netter MD School of Medicine at Quinnipiac University, where he trains medical students in vascular and surgical principles—a role that keeps his practice connected to emerging evidence and the next generation of clinicians.
Griffin Faculty Physicians, as a non-profit multi-specialty medical group, also supports this educational mission organizationally—participating in training resident physicians through Griffin Hospital’s Internal Medicine and Preventive Medicine programs, as well as physician assistant and nurse practitioner students from Quinnipiac University. Dr. Sergi has been recognized as a Connecticut Magazine Top Doctor annually from 2021 through 2025, reflecting sustained peer recognition within the state’s vascular surgery community.
Who Should Consider a Vascular Evaluation?
Because PAD so often goes unrecognized, understanding who faces elevated risk is an important starting point. Griffin Faculty Physicians highlights several patient categories for whom proactive vascular assessment is warranted:
- Adults aged 65 and older, especially those with any existing cardiovascular condition
- Adults aged 50 or older who smoke, have diabetes, or have a family history of PAD
- Anyone experiencing leg pain, cramping, or fatigue during walking that reliably resolves with rest
- Patients with non-healing wounds on the feet or lower legs, particularly those with diabetes
- Individuals with known carotid artery disease, coronary artery disease, or a prior heart attack or stroke
- People experiencing persistent leg swelling, skin changes, or a history of deep vein thrombosis
- Patients whose primary care provider has noted reduced or absent pulses during a routine physical examination
Early identification of PAD enables more than symptom relief—it supports systemic cardiovascular risk reduction that can directly lower the probability of future heart attack or stroke, outcomes that matter far beyond what happens in the legs.
Conclusion
Peripheral artery disease is a chronic, progressive condition whose consequences extend well beyond reduced circulation in the legs. It signals systemic atherosclerosis, elevates cardiovascular event risk, and without thoughtful management, can lead to severe functional limitation or limb loss. Managing it effectively demands thorough evaluation, personalized treatment planning, appropriate procedural capabilities, and a sustained commitment to long-term monitoring.
The approach taken by Griffin Faculty Physicians—grounded in prevention, supported by clinical research, and led by a specialist with board certification, fellowship training, and sustained academic involvement—reflects exactly the kind of integrated vascular care that this condition requires. For patients across Connecticut seeking expert evaluation of peripheral artery disease or related vascular health concerns, the program represents a credible and comprehensive point of access to that care.
