At Yale Medicine, our team of highly trained vascular surgeons are here to help with a variety of circulation issues. This includes anything from blocked blood vessels and stubborn wounds to conditions that could lead to losing a limb. Our goal is to give complete care that's as easy on you as possible, which is why we focus on techniques that don't require major surgery, like treatments done inside the blood vessels themselves. Our doctors give personalized and complete care to adults with vascular problems. We rely on the newest and most advanced equipment and methods to diagnose and treat these conditions. Specialized care is offered in the following areas: Abdominal and thoracic aortic aneurysm: Bulges in the main artery that can occur in the belly or chest area. Aortoiliac occlusive disease: Blocked arteries that supply blood to the abdomen, pelvis, and legs. Carotid artery stenosis: Narrowed arteries in the neck that can reduce blood flow to the brain. Claudication: Treatments to help relieve cramping in the legs while walking or exercising Diabetic ulcers: Sores that are slow to heal in people with diabetes. Dialysis access: For patients who need dialysis (a treatment for kidney failure), we create an entry point into the bloodstream that the dialysis machine can use. Foot ulcers: Sores on the feet that can develop due to poor circulation or other health issue. Lower extremity artery conditions Lower extremity vein conditions Renal vascular disease: Conditions that affect blood flow to the kidneys. Thoracic aortic aneurysm and aortic dissection: Bulges and tears in the part of the main artery that runs through the chest. Thoracic outlet syndrome: Discomfort or circulation problems caused when blood vessels or nerves just below the neck are compressed. Varicose veins: Treatments to remove or reduce enlarged veins that appear most often on the legs. Visceral artery disease: Blood vessels that supply the internal organs, ensuring they're not narrowed or blocked.

At Laboratory Medicine, we study the molecular and cellular components of blood and other body fluids. This work is crucial to diagnosing and managing illness and understanding the mechanisms and origins of disease.Our physicians, known as clinical pathologists, provide consultations to other doctors regarding optimal laboratory diagnostic approaches and the interpretation of complex laboratory tests. Our team includes pathologists, scientists, phlebotomists, medical technicians, technologists, and others who perform important support functions for our state-of-the-art laboratory. We are available every day, 24 hours a day, for physicians. We perform approximately 10 million tests each year, and also provide specialized high-tech testing to other hospitals in the Yale New Haven Health System and institutions throughout New England, and as far away as Puerto Rico. We also operate multiple satellite facilities and patient service centers located throughout the state. We ensure that every test we offer—at every location—is accurate and reliable. When physicians request to have patients’ blood drawn, here is what happens: Collection: A doctor, nurse, technician, or phlebotomist will draw the patient’s blood. Several tubes may be needed for different types of tests. Depending on what illness the patient might have, his or her doctor may want to obtain a urine sample, throat swab, or other sample. After the sample is collected, the container is labeled with the patient’s name and other information. The sample is received and processed by the Laboratory, and testing begins: Chemistry Testing Blood and other bodily fluids are tested for chemicals, drugs, and substances that indicate disease. We check cholesterol and other tests for risk of heart disease, glucose to monitor diabetes, or thyroxin to monitor the thyroid gland. Hematology Testing We analyze the amount and function of blood cells and plasma. Examples include the Complete Blood Count (CBC) that tells the doctor how many cells of each type are in the patient’s blood, and the prothrombin time (PT) to measure the time it takes for the blood to clot. Microbiology Testing We test a variety of specimen samples for infections caused by bacteria, fungi, or parasites. We often do urine cultures for urinary tract infections. Virology Testing We test for viral infections. This includes rapid tests for respiratory viruses such as influenza, molecular tests for noroviruses, and antibody tests for HIV. Immunology/Molecular Diagnostics Some tests are used to determine whether the immune system is functioning properly. State-of-the-art analysis of DNA and RNA is used to test for a variety of diseases and for the risk of developing certain diseases. Other specialized tests include the ANA, used to screen for autoimmune disease, and Factor V Leiden genotyping for patients with blood clots. Tumor Profiling Laboratory This lab analyzes tumor DNA to predict the sensitivity or resistance of tumors to a

Covering every aspect of health care for adults, Internal Medicine is the largest department in the Yale School of Medicine, and the largest clinical service at Yale New Haven Hospital.
