Spigelian hernia Spigelian hernia A Spigelian hernia (or lateral ventral hernia) is a hernia through the Spigelian fascia, which is the aponeurotic layer between the rectus abdominis muscle medially, and the semilunar line laterally. These are generally interparietal hernias, meaning that they do not lie below the subcutaneous fat but penetrate between the muscles of the abdominal wall; therefore, there is often no notable swelling. Spigelian hernias are usually small and therefore risk of strangulation is high. Most occur on the right side. (4th–7th decade of life.) Compared to other types of hernias they are rare. Patients typically present with either an
Femoral artery on the type of intervention or diagnostic. The site for optimally palpating the "femoral pulse" is in the inner thigh, at the mid-inguinal point, halfway between the pubic symphysis and anterior superior iliac spine. Presence of a "femoral pulse" has been estimated to indicate a systolic blood pressure of more than 50 mmHg, as given by the 50% percentile. The femoral artery can be used to draw arterial blood when the blood pressure is so low that the radial or brachial arteries cannot be located. The femoral artery is susceptible to peripheral arterial disease. When it is blocked through atherosclerosis,
