Anatomic considerations Femoral artery The femoral artery is a continuation of the external iliac artery and is located just below the inguinal ligament. Here, the common femoral artery gives off the superficial femoral and profunda femoral arteries.
The femoral artery is usually easily palpable at the groin and widely used for arterial access.
When accessed for interventional procedures, the artery should ideally be cannulated below the inguinal ligament so that manual pressure can be applied to obtain hemostasis after the catheters and sheath are removed. Cannulation too proximal complicates manual compression because the artery dives into the pelvic cavity ie, retroperitoneal space and is covered by the firm inguinal ligament.
Location of femoral artery in relation to the nerve and vein. It is important to make the needle puncture below the inguinal ligament so that the vessel can be manually compressed.
View Media Gallery Aortic arch The aortic arch gives of the right innominate, left common carotid, and the left subclavian arteries.
The right innominate artery gives off the right common carotid and then becomes the subclavian artery. The subclavian arteries become the axillary arteries as they pass under the axilla.
In rare cases, a radial artery may originate from the brachial artery in the upper arm. Thus, when performing a radial artery cannulation, the anatomy should be reviewed before passing any catheters or guidewires.
As it approaches the elbow, it becomes slightly superficial and is very close to the median nerve. Distal to the elbow, the brachial artery travels under the supinator and pronator radii teres.
At this junction, it divides into the ulnar and radial arteries. At this point, it passes laterally along the forearm until it reaches the wrist. In the mid forearm, the artery runs between the flexor carpi radialis and supinator longus tendons.
When it reaches the wrist, the radial artery is easily palpated above the trapezium and scaphoid bones and the external lateral ligament. Radial and ulnar arteries. Because of the tortuosity of the radial artery, the wrist needs to be extended prior to catheterization.
View Media Gallery If cannulation of the artery is attempted too distally, the reticulum will be encountered, and the artery is often branched at this point. It is important, therefore, to attempt cannulation approximately cm proximal to the flexion crease of the wrist.
At the level of the hand, the radial artery traverses the space between the metacarpal bones of the thumb and index finger and enters the palm. The vessel then crosses the base of the metacarpal bone of the little finger and joins with the deep communicating branch of the ulnar artery, resulting in a patent deep palmar arch.A stethoscope with bell facing, diaphragm away.
“Tunable diaphragms” can be used to listen to high and low pitched sounds by gently on the patient for low sounds, and more firmly for high ones.

Results from a new study may lead to approval of what could be the first drug that ameliorates potentially deadly reactions in children with severe peanut allergies. This interactive Journal feature presents the case of a year-old man with a history of hypertension and hyperlipidemia who is found to have an asymptomatic unilateral carotid stenosis of 70 to 80%.
I will enter from the right femoral vein which is located in the upper thigh (Elsevier Mosley, ) and follow a path to the lower lobe of the right lung via the right pulmonary artery.
I will be describing the structures that I pass by and through.
