Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch. A continuous suture where the needle enters and exits the epidermis along the plane of the skin.
The horizontal mattress stitch is a suture technique used to close wounds.It everts skin well and spreads tension along the wound edge. [1] [2] [3] This makes it ideal for holding together fragile skin [4] as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs.
They tend to absorb this suture at a higher rate. Special precautions should be taken in elderly patients and patients with history of anemia and malnutrition conditions. As with any suture material, adequate knot security requires the accepted surgical technique of flat and square ties. The PDS suture knots must be properly placed to be secure.
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure. [6]
Setons can be tied tightly or loosely and with different materials, depending on the anatomical location of the fistulae and what may be medically required. A seton might be tied loosely as a palliative measure to avoid septic and painful exacerbations, or as temporary measure before surgical excision as in fistulotomy or fistulectomy. In some ...
It is possible that this is the result of recent advances in suture technology, along with increasingly risk-conscious surgical practice. Certainly modern synthetic sutures are more predictable and less prone to infection than catgut, silk and linen, which were the main suture materials used up to the 1990s.
Marsupialization is the surgical technique of cutting a slit into an abscess or cyst and suturing the edges of the slit to form a continuous surface from the exterior surface to the interior surface of the cyst or abscess. Sutured in this fashion, the site remains open and can drain freely.
This tragedy inspired Carrel to develop new techniques for suturing blood vessels, such as the "triangulation" technique using three stay-sutures to minimize damage to the vascular wall during suturing. Carrel learned this technique from an embroideress, and later incorporated it into his work.
