It is often useful to resect a short segment of costal cartilage to facilitate closure of the chest wall. Disadvantages include disruption of the innervation to the rectus lying medially. Optimal exposure requires appropriate placement of retractors; use of a retractor system that can be contoured to the incision (eg, the Thompson retractor system, Thompson Surgical Instruments [Traverse City, MI], or other table-based self-retaining systems) is helpful in this regard (Fig. Always adhere to medical school/local hospital guidelines when performing examinations or clinical procedures. Purpose: Both midline and transverse abdominal incisions are used for exposing the infrarenal aorta. The incision is then carried down to the linea alba using either electrocautery or a scalpel; the decussation of fascial fibers in the upper abdomen serves as an important landmark for the midline. Some common incision sites are discussed below. Vertical midline incision: the linea alba and peritoneum are divided. Potential disadvantages include the requirement for specialized equipment and training as well as the lengthy surgical times. The Surgical Technique of Caesarean Section: What is Evidence Based?

Superiorly, additional access can be obtained by directing the upper portion of the incision along the costal margin toward the xiphoid process (Fig. Disadvantages of a vertical incision include: Mediocre cosmetic results Higher infection rates, operative time, and hemorrhage with a paramedian incision Wound dehiscence (separation of the edges of wounds) and hernia may be common Oblique incisions are of two types: Use the arc, rather than direct contact, to prevent excessive devitalization of tissue. Disadvantages include patients experiencing more pain than they would from a transverse incision, particularly during deep breathing postoperatively, and the incision is perpendicular to the Langer's skin tension lines resulting in poorer cosmesis. The external oblique, internal oblique, and transversalis muscles are exposed, and divided in the direction of their fibers. Structures within the transpyloric plane: Complications are best considered in terms of specificity and chronicity; i.e. This area is called the perineum.
