He might leave his wife (or wives), then widow (or widows), a dower (often a third or a half of his estate) to support her as dowager.As an external symbol of the fact that they are married, each spouse commonly wears a wedding ring on the ring finger; whether this is on the left or right hand depends on the countrys tradition. Husband further refers to the institutionalized form in relation to the spouse and offspring, unlike father, a term that puts a man into the context of his children. Also compare the similar husbandry, which in the 14th century referred to the care of the household, but today means the "control or judicious use of resources", conservation, and in agriculture, the cultivation of plants and animals, and the science about its profession. Western culture
Historical status
In premodern heterosexual unions (ancient Roman, medieval, and early modern history), a husband was obliged to protect and support not only his wife and children, but servants and animals of his domain. The father (as the "patron") was awarded with much authority, differing from that of his wife (in these cultures, no polygamy existed).In the Middle Ages and Early Modern European history, it was unusual to marry out of love, but then doing so became an influential ideal. During this period, a husband in a heterosexual marriage had more opportunities in society than his wife, who was not recognized as legally independent. Contemporary status
In contemporary secularized Western culture, the rights of the spouses have been made equal.
A decrease in ABI of 15%–20% would be diagnostic of PAD.If ABIs are abnormal, the next step is generally a lower limb Doppler ultrasound to look at the site of obstruction and extent of atherosclerosis. Other imaging can be performed by angiography, where a catheter is inserted into the common femoral artery and selectively guided to the artery in question. While injecting a radio-dense contrast agent, an X-ray is taken. Any blood flow-limiting blockage found in the X-ray can be identified and treated by procedures including atherectomy, angioplasty, or stenting. Contrast angiography is the most readily available and widely used imaging technique. Modern computerized tomography (CT) scanners provide direct imaging of the arterial system as an alternative to angiography.Magnetic resonance angiography (MRA) is a noninvasive diagnostic procedure that uses a combination of a large magnet, radio frequencies, and a computer to produce detailed images of blood vessels inside the body. The advantages of MRA include its safety and ability to provide high-resolution, three-dimensional imaging of the entire abdomen, pelvis and lower extremities in one sitting. Classification
The two most commonly used methods to classify peripheral artery disease are the Fontaine and the Rutherford systems of classification.
