Introduction to Pelvic Anatomy The pelvis is a confluence of musculoskeletal, vascular, nervous, and reproductive structures. Its layered architecture demands a systematic approach to understand the spatial relationships that define gynecologic surgeries. Pelvic Bone Structures Pelvic bones: Ilium, ischium, pubis, sacrum, and coccyx form the bony pelvis, providing structural support and attachment points for muscles and ligaments. Pelvic inlet and outlet: Boundaries define the space through which structures pass, crucial for procedures like cesarean sections and pelvic surgeries. Pelvic Musculature and Ligaments Pelvic floor muscles: Levator ani (pubococcygeus, puborectalis, iliococcygeus) and coccygeus muscles provide support for pelvic organs. Ligaments: Broad ligament, cardinal ligament, uterosacral ligament, round ligament, and sacrospinous ligament maintain organ positioning and serve as surgical landmarks. Vascular Anatomy Arterial supply: Internal iliac artery and its branches, including uterine, vaginal, obturator, and superior gluteal arteries. Venous drainage: Corresponding veins, notably the uterine and vaginal venous plexuses, which are important during hemorrhage control. 2 Nervous System Pelvic plexus: Contains autonomic fibers essential for bladder, bowel, and sexual function. Sacral nerves: S2-S4 contribute to pudendal nerve, critical in innervation of perineal muscles. Key Surgical Landmarks in Gynecologic Procedures Precise identification of landmarks minimizes intraoperative risks and enhances surgical outcomes. Uterus and Adnexa Round ligament: Located anteriorly, helps identify the lateral uterine border.1. Uterine vessels: Cross over the ureter at the level of the uterine cervix, important2. during hysterectomy. Ovaries and fallopian tubes: Situated within the broad ligament, their vascular3. pedicles are key during salpingo-oophorectomy. Pelvic Vessels and Nerves Ureter: Crosses under the uterine artery near the cardinal ligament; awareness1. prevents ureteral injury. Uterine artery: A vital structure that needs careful ligation during hysterectomy.2. Pudendal nerve: Located near the sacrospinous ligament, essential for perineal3. innervation. Surgical Planes and Spaces Retzius space: Between the pubic symphysis and bladder, accessed in anterior approaches. Pararectal and paravesical spaces: Developed during dissection for procedures like lymphadenectomy. Rectovaginal and vesicovaginal spaces: Critical for posterior and anterior colpotomies. Common Gynecologic Surgical Procedures and Anatomical Considerations A detailed understanding of anatomy underpins techniques such as hysterectomy, myomectomy, and pelvic floor repairs. 3 Hysterectomy Approach: Abdominal, vaginal, or laparoscopic, each with specific anatomical1. considerations. Key steps:2. Identification of the broad ligament and uterine vessels Dissection along the vesicovaginal and rectovaginal planes Secure ligation of uterine arteries at their origin from the internal iliac arteries Risks: Ureteral injury, bleeding, bladder or bowel injury; knowledge of pelvic3. anatomy reduces these risks. Myomectomy Anatomical focus: Careful dissection of myomas from the uterine wall, preserving1. the endometrial and serosal layers. Vascular considerations: Uterine and radial arteries supply fibroids; ligating these2. reduces bleeding. Pelvic Floor Repair Goals: Restore support to prevent or treat prolapse.1.
