Femoral Triangle. Draw it in 3 mins! [Easy Anatomy]

Femoral Triangle made easy! Read on below and make sure you subscribe for more videos like this! (Timestamps below) We are drawing a simple diagram to illustrate the hollow region located in the anterior thigh referred to as the Femoral Triangle. It is also known as ‘Scarpa’s Triangle’ & ‘Femoral Trigone’. This is an easily accessible area in which we find multiple neurovascular structures passing through. How to draw and memorize the borders, contents, and additional structures. We’ll also tell you about the clinical relevance! ✅ Drawing the Femoral Triangle 🖍📄 Grab some paper and your colored pencils, markers or crayons! In this lesson you’ll learn how to vision the femoral triangle in your head and the location for the neurovasculature. Before we begin labeling, start with this... Step by step 1.Draw a triangle with the two corners on top and the last corner towards the bottom on the right. 2.Since we are drawing the right femoral triangle, label lateral on left with an ‘L’ and medial on the right with a ‘R’. This will guide you for the neurovasculature. 3. Now find the midpoint of the top of the triangle and draw down a red line for a artery 4. Left (lateral) of the red line draw a yellow line for a nerve 5. Right (medial) of the red line draw a blue line with a branch coming off for the vein. 6. Finally all the way to the right draw a green circle and line for the lymph vessels. ✅ Overview This lesson walks you through the right anterior thigh showcasing the Femoral Triangle and its content. We’d like for you to always think the ‘Navy Sails’ when labeling the femoral triangle. For the borders recall the mnemonic ‘SAIL’ and for the content inside you’ll use the mnemonic ‘NAVEL’. Let’s see them here: ✅ Mnemonic The borders of the Femoral Triangle are made up the superior border which is the ‘Inguinal Ligament (IL)’, the medial border which is the ‘Adductor longus muscle (A)’, and the lateral border which is the ‘Sartorius muscle (S)’. S A I L ⛵️ S: Sartorius muscle - medial border of the sartorius muscle. A: Adductor longus muscle - medial border of this muscle forms the border and the rest of this muscle forms part of the floor of the triangle. IL: Inguinal ligament - which is a ligament that runs from the anterior superior iliac spine to the pubic tubercle. The content of the Femoral Triangle contains some of the major neurovascular structures of the lower limb. This mnemonic is used from Lateral to Medial in order. N A V E L ⚓️ N: Femoral nerve - it innervates the anterior compartment of the thigh, and provides sensory branches to the leg and foot. A: Femoral artery - its responsible for the majority of the arterial supply to the lower limb. V: Femoral vein and the great saphenous vein which drains into the femoral vein within the triangle. E: Empty Space - nothing special here L: Lymph vessels and deep inguinal lymph nodes are found here High Yield and must-know facts! ✅ Femoral Pulse Just inferior to where the femoral artery crosses the inguinal ligament, it can be palpated to measure the femoral pulse. The femoral artery crosses exactly midway between the pubic symphysis and anterior superior iliac spine (known as the mid-inguinal point). This artery can be used for drawing blood when the pressure in the radial & ulnar arteries, of the upper limb, are too low to locate. ✅ Access to the Femoral Artery The femoral artery is located superficially within the femoral triangle so its really easy to access. Thus making it suitable for an array of clinical procedures. For example Coronary angiography. For this, we catheterize the femoral artery with a long and thin tube. This tube is used to navigate up the external iliac artery, to the common iliac artery, the aorta, and into the coronary vessels of the heart. We then inject this radio-opaque dye into the coronaries, then we inspect for any wall thickening or blockages that are visible via x-ray. Pretty cool isn’t it? 🫀 In the world of cardiology, catheterization of the femoral artery approach is useful for obtaining access into the ascending aorta for aortic valve replacements as well! And don’t worry the left side of the heart is also easily accessible using this approach. To further geek out... The femoral vein is frequently used to obtain access to the right side of the heart through the inferior vena cava. This approach is commonly used when repairing a patent foramen ovale (remember this?), well if you don’t then go brush up. It’s a congenital heart defect involving the persistence of an embryological opening between the right and left atria.
