Transversalis Fascia (of Gallaudet)<\/h2>\n\n\n\n

This fascia is a two layered structure (bilaminar). The anterior layer is adherent to the rectus abdominis muscle. The posterior layer lies in between the anterior layer and the peritoneum. It divides this space into an anterior (vascular space) and a posterior (Space of Bogros<\/a>). Medially it is continuous with the space of Retzius. One should work in the space of Bogros to prevent unnecessory oozing. <\/p>\n\n\n\n

Prevesical space of Retzius<\/h2>\n\n\n\n

The preperitoneal space that lies deep to the supravesical fossa and the medial umbilical fossa is the prevesical space of Retzius (Described in 1858, by Swedish anatomist Anders Retzius). This space contains loose connective tissue and fat.<\/p>\n\n\n\n

Important structures in this space are:<\/p>\n\n\n\n

Arteries<\/strong><\/h3>\n\n\n\n
  1. External iliac artery<\/li>
  2. Inferior epigastric artery and its branches<\/li><\/ol>\n\n\n\n

    Veins<\/strong><\/h3>\n\n\n\n
    1. External iliac vein<\/li>
    2. Inferior epigastric veins<\/li>
    3. Deep venous circulation<\/li><\/ol>\n\n\n\n

      Nerves<\/strong><\/h3>\n\n\n\n
      1. Lateral femoral cutaneous nerve<\/li>
      2. Genitofemoral nerve<\/li>
      3. Femoral nerve<\/li>
      4. Ilioinguinal nerve<\/li>
      5. Iliohypogastric nerve<\/li>
      6. Lymphatics and lymph nodes<\/li><\/ol>\n\n\n\n

        Pubic branches: <\/h2>\n\n\n\n

        -The inferior epigastric artery gives rise to anterior pubic artery, which accompanied with the iliopubic vein crosses the superior pubic ramus. In 25-30% of individuals, the anterior pubic branch is large and can replace the obturator artery. This large arterial branch (Aberrant obturator artery) can partially encircle the neck of a hernia sac and be injured in a femoral hernia repair. It could also be injured while dissecting on to the Cooper\u2019s ligament. So the whole anastomotic ring is known as the \u2013 \u2018Corona Mortis\u2019 (circle of death) (10).<\/p>\n\n\n\n

        Deep venous circulation of the preperitoneal space (Bendavid): – <\/h2>\n\n\n\n

        The venous circle\/ deep venous circulation of Bendavid(11) is located at the subinguinal space of Bogros. It is a network of deep inferior epigastric, rectusial, suprapubic and retropubic veins. These are important because damage to these vessels is easy and usually leads to haematoma formation.<\/p>\n\n\n\n

        Nerves in the inguinal region: –<\/h2>\n\n\n\n

        The following three nerves are at risk for injury during dissection-<\/p>\n\n\n\n

        1. Lateral femoral cutaneous nerve<\/li>
        2. Femoral branch of genitofemoral nerve<\/li>
        3. Obturator nerve<\/li><\/ol>\n\n\n\n

          The following nerves are usually not at risk during dissection, but can be injured if excessive pressure is applied during mesh fixation.<\/p>\n\n\n\n

          1. Ilioinguinal nerve<\/li>
          2. Iliohypogastric nerve<\/li>
          3. Genital branch of genitofemoral nerve<\/li><\/ol>\n\n\n
