A second bypass may be required if a blockage forms in the bypass graft later on. Over time, there is a decreasing trend of percentage patency (likelihood a vessel will remain open) in popliteal bypass surgery, 88% in the first year, 79% and 76% at 3 and 5 years respectively. [13]
To image the lower limb vascular anatomy, the common femoral artery (CFA) is chosen as the site of entry. However, CFA entry can only be assessed by retrograde puncture. Therefore, a catheter is advanced retrogradely through the contralateral common femoral artery into common iliac artery, crossing the midline into ipsilateral CFA.
Atherectomy is a minimally invasive technique for removing atherosclerosis from blood vessels within the body. It is an alternative to angioplasty for the treatment of peripheral artery disease, but the studies that exist are not adequate to determine whether it is superior to angioplasty. [1]
A crossed-field amplifier (CFA) is a specialized vacuum tube, first introduced in the mid-1950s and frequently used as a microwave amplifier in very-high-power transmitters. Raytheon engineer William C. Brown 's work to adapt magnetron principles to create a new broadband amplifier is generally recognized as the first CFA, which he called an ...
The AutoAnalyzer is an automated analyzer using a flow technique called continuous flow analysis (CFA), or more correctly segmented flow analysis (SFA) first made by the Technicon Corporation. The instrument was invented in 1957 by Leonard Skeggs, PhD and commercialized by Jack Whitehead's Technicon Corporation.
In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
SFA may refer to: In science and technology. In medicine ... Substance flow analysis, a method of analyzing the flows of a material in a well-defined system;
Crossed field test antenna installed in Silsden, U.K. A crossed field antenna (CFA) is a controversial type of radio antenna for long and mediumwave broadcasting, patented by F. M. Kabbary and M. C. Hately in 1986, which was claimed to have the same efficiency as a conventional antenna but only one-tenth the overall height.
