Non-suture external cuff techniques for microvascular anastomosis.

Microvascular anastomosis can be achieved by eversion of the upstream vessel end over an external cuff and insertion of this into the downstream vessel. This technique, first described in 1900, was initially tested in 13 rat femoral vein anastomoses using small polythene cuffs. Two anastomoses failed and 11 were patent at 7 days. After control studies, in 16 rat epigastric flaps the femoral vein in the vascular pedicle was divided and anastomosed using an external cuff. Thirteen flaps survived. The principles underlying this method appear sound, and form the basis for microvascular anastomotic devices currently being developed.

Complications of radial forearm flap donor sites.

The complications of radial forearm flap donor sites in 15 patients from two centres have been reviewed. The complications included skin graft failure, swelling of the hand, stiffness of joints, reduced strength and sensation, cold-induced symptoms and fractures of the radius. Methods to reduce the incidence of such complications are discussed.

Reconstructive surgery in the treatment of intraoral cancer.

Patients with intraoral cancer present to various specialties. A series of 63 patients shows the importance of modern reconstructive surgery for patients treated by tumor excision. The reasons why a variety of techniques must be available to the patient are discussed. The advantages and disadvantages of some of these methods of reconstruction are reviewed.

The vascular basis of the radial forearm flap.

The radial forearm flap is one of several valuable fasciocutaneous flaps. Therefore, its arterial and venous supply has been studied by dissection of 56 cadavers using various techniques, such as ink, latex, and barium sulfate injections. The relevant arterial branches tend to be in three groups with three associated and anastomosing perfusion zones. The blood supply of the distal radius is shown by latex injections. The vessels to tendons and nerves are briefly discussed. The flap is drained by superficial veins or radial artery venae comitantes or both. Each arterial perforator has one or two associated veins through which blood can pass into the venae comitantes. It is confirmed that the veins have valves, through which reverse flow has to occur in the pedicle of distally based island flaps. An explanation of how this is possible is given. The relevance of the findings to fasciocutaneous flaps in general is discussed.

Landmarks in the anatomical study of the blood supply of the skin.

The description of fasciocutaneous flaps by Pontén (1981) and the extensive, continuing studies of Cormack and Lamberty (1984) have revived interest in the anatomical study of the blood supply of the skin. It is important to know the results and conclusions of previous investigators. The purpose of this paper is to indicate some of these past achievements.

Are systemic prophylactic antibiotics necessary for burns?

Systemic prophylactic antibiotics to prevent Streptococcus pyogenes infections in newly burnt patients have been recommended for many years. However, a review of patients admitted to one Regional Burns Centre shows only a small percentage develop such infections, even if no systemic prophylaxis is used. Other Centres have reported similar results. Possible uses of systemic prophylactic antibiotics in patients with burns are reviewed. It is suggested that these antibiotics are restricted to a small minority of patients to prevent peri-operative septicaemia and gas-gangrene.

Psychological and social outcome of prominent ear correction in children.

The effectiveness of surgery to correct prominent ears in relieving the psychosocial distress of children has been analysed in this prospective study. 30 children and their families were assessed preoperatively and again 12 months postoperatively. It was found that whilst prominent ear correction improved the well-being of 90% of the children, there was a small group of acutely distressed children who remained dissatisfied with outcome. These were children who were socially isolated prior to surgery. Careful screening and referral back to the family doctor of the more distressed children is recommended.
