Arterial anatomy of the upper extremity. By David Terfera, Shereen Jegtvig . The medial thigh with the common femoral, femoral (superficial femoral), deep femoral, and great saphenous (greater saphenous) veins being drawn to illustrate their location in the thigh. To understand how this works, let’s start with the basic parts of the hand, which are: The bony background of the hand is very interesting. (A) In this example, both the popliteal artery (. The quality of imaging equipment varies widely. e-Anatomy is an award-winning interactive atlas of human anatomy. “I would honestly say that Kenhub cut my study time in half.”
Just remember: the femoral vein is the main deep vein that runs through the thigh. Extremity Venous Anatomy and Technique for Ultrasound Examination. This may require the use of several transducers: a high-frequency linear probe (10 to 18 MHz) with a small footprint for superficial veins such as the saphenous, distal tibial veins, and most of the arm veins; a midrange linear probe (5 to 9 MHz) for most of the deep veins of the legs and deeper veins of the arm; and a lower-frequency probe (2 to 5 MHz) for the iliac veins and inferior vena cava and also to see leg veins in heavy patients. They constrict when the environment is cold to help preserve body heat. Although they both transport blood, the veins perform multiple different functions. Check for errors and try again.
Knowing the clinical anatomy of these structures is important because your future patients need arms and legs to get from place to place and pick up things when they get there. When they are not functioning well, blood can pool at the skin level and chronic stasis changes and ulcers may result. The shoulder joint is reinforced with two groups of muscles, superficial and deep. Knowing the clinical anatomy of these structures is important because your future patients need arms and legs to get from place to place and pick up things when they get there. 18.1 and 18.2 ). FIGURE 13-4 Arterial anatomy (A) and osseous landmarks (B) at the elbow. Knowing the clinical anatomy of these structures is important because your future patients need arms and legs to get from place to place and pick up things when they get there.

Choose from 500 different sets of extremities anatomy upper flashcards on Quizlet. Figures 13-2 to 13-5 are detailed arteriographic views of specific regions of the upper extremity arterial tree, beginning at the aorta and extending to the digits. The artery is thicker walled but usually the smaller of the two (if the limb being examined is positioned below the heart). Because conventional arteriography remains the gold standard, angiographic images are used in this chapter, as they best depict anatomic detail. The arm is the portion of the upper extremity between the shoulder and elbow. We know that reading about twenty muscles, two compartments and five layers can be monotonous, so we have designed these study units with video tutorial and integrated quizzes to make this topic more interesting, and your life easier! Transverse views demonstrating proper compression of a vein. Normal anatomy, common variants, and major collateral routes, The following terms are used to describe extremity anatomy in this chapter. This topic page will briefly discuss the upper extremity anatomy in order to introduce you to the main regions of the upper limb, which includes: the shoulder, arm, elbow, forearm and hand. The anterior compartment contains superficial, intermediate and deep layers, whilst the posterior compartment contains superficial and deep layers. Part of Clinical Anatomy For Dummies Cheat Sheet . Also, we have prepared a special quiz for you to solidify your knowledge about the upper limb anatomy. Their job is not to be the primary channels for returning blood to the heart, but to get blood close to the skin surface so that the veins can help to regulate body temperature. Although they both transport blood, the veins perform multiple different functions. Their job is to act as the main conduits that transport blood back to the heart. The marker is indicating the course of the great saphenous vein. These clots in the superficial system are less likely to cause major, clinically significant pulmonary embolism because they are usually smaller than clots found in the deep veins, and they are less likely to be dislodged because they are not surrounded by muscle. Communicating vessels usually connect the deep and superficial arches, as shown here. Thorax. When the body needs to cool down, they dilate to shunt large amounts of warm blood to the skin so that heat escapes from the body. Present accreditation protocols require transverse compression views and longitudinal views with color and pulsed Doppler information to be performed. 18.13 ).
Short-axis femoral vein examination. Some laboratories simply look for noncompressibility of the vein or echogenicity in the vein lumen to make the diagnosis of DVT. This anatomy section promotes the use of the Terminologia Anatomica, the international standard of anatomical nomenclature. Last but not least, is the neurovascular compartment.
When in anatomical position (supination), the radius is found laterally while the ulna is medially in the forearm. Further, each compartment has layers. Visualization of intraluminal thrombus and incomplete compression of the vein are the primary criteria for duplex imaging for DVT. Finally the digits are supported with three consecutively attached bones called the proximal, middle and distal phalanges, all specifically named by adding I-V at the end. Their job is to keep blood moving from the superficial system into the deep system.
The vein previously called the superficial femoral has recently been renamed the femoral vein because many people would hear the term superficial femoral vein and confuse it with the great saphenous vein, which is a superficial vein.
Clots in the superficial system are less likely to cause major, clinically significant pulmonary embolism because they are usually smaller than clots found in the deep veins, and they are less likely to be dislodged because they are not surrounded by muscle. John S. Pellerito, MD, FACR, FSRU, FAIUM , The evaluation of arterial disease of the extremities requires knowledge of vascular anatomy. The arm is the portion of the upper extremity between the shoulder and elbow.
Many anatomic variants can occur in the arterial tree of the upper extremities.
