Umbilical Arteries: Specialized arterial vessels in the umbilical cord. They carry waste and deoxygenated blood from the Fetus to the mother via the Placenta. In humans, there are usually two umbilical arteries but sometimes one.

Abdominal Exam I: Inspection and Auscultation

JoVE 10088

Gastrointestinal disease accounts for millions of office visits and hospital admissions annually. Physical examination of the abdomen is a crucial tool in diagnosing diseases of the gastrointestinal tract; in addition, it can help identify pathological processes in cardiovascular, urinary, and other systems. As physical examination in general, the examination of the abdominal region is important for establishing physician-patient contact, for reaching the preliminary diagnosis and selecting subsequent laboratory and imaging tests, and determining the urgency of care. As with the other parts of a physical examination, visual inspection and auscultation of the abdomen are done in a systematic fashion so that no potential findings are missed. Special attention should be paid to potential problems already identified by the patient's history. Here we assume that the patient has already been identified, and has had history taken, symptoms discussed, and areas of potential concern identified. In this video we will not review the patient's history; instead, we will go directly to the physical examination. Before we get to the examination, let's briefly review s

Peripheral Vascular Exam

JoVE 10122

The prevalence of peripheral vascular disease (PVD) increases with age and is a significant cause of morbidity in older patients, and peripheral artery disease (PAD) is associated with cardiovascular and cerebrovascular complications. Diabetes, hyperlipidemia, hypertension, and tobacco use are important disease risk factors. When patients become symptomatic, they frequently complain of limb claudication, defined as a cramp-like muscle pain that worsens with activity and improves with rest. Patients with chronic venous insufficiency (CVI) often present with lower extremity swelling, pain, skin changes, and ulceration. While the benefits of screening asymptomatic patients for PVD are unclear, physicians should know the proper exam technique when the diagnosis of PVD is being considered. This video reviews the vascular examination of the upper and lower extremities and abdomen. As always, the examiner should use a systematic method of examination, though in practice, the extent of the exam a physician performs depends on their suspicion of underlying PVD. In a patient who has or is suspected to have risk factors for vascular disease, the vascular exam should be thorough, beginning with inspection, fo
