The effects of the pentoxifylline on survival of the skin flaps in streptozotocin-diabetic rats.

Skin flaps are frequently performed for diabetic patients in spite of countless detrimental effects of diabetes on flap survival. This study was planned because only a few clinical experiments have been performed on the effect of pentoxifylline (PTX) on the flaps in diabetic-animals. We studied 4 groups of rats: group 1, diabetic PTX treatment; group 2, diabetic control; group 3, nondiabetic PTX treatment; group 4, nondiabetic control.

A reverse-flow composite flap in the rat.

Reverse-flow flaps are currently particularly used for the reconstruction of defects of the distal part of the extremities. Despite their common usage there have been many reports of postoperative complications, especially resulting in partial or total flap necrosis. There is insufficient knowledge of flap haemodynamics, physiology and wound healing properties in reverse-flow flaps.

Expansion of surviving skin paddle of neurocutaneous island flaps in rats by VEGF.

The purpose of this study was to investigate whether vascular endothelial growth factor (VEGF) can enlarge the skin paddles of neurocutaneous flaps in rats. Wistar albino rats were used in four groups: Group 1, (n = 10): neurocutaneous island flap; Group 2, (n = 10): neurocutaneous island flap, surgical delay; Group 3, (n = 10): neurocutaneous island flap, VEGF; Group 4, (n = 10): graft. A 3 x 3-cm, neurocutaneous island flap was elevated on the anterolateral skin of the thigh of the rats.

A random-pattern skin-flap model in streptozotocin diabetic rats.

Background: Flap operations are frequently performed in diabetic patients. Nevertheless, we could find no experimental study examining diabetes mellitus's effect on the flaps' survival. For this reason, we designed this study as a random-pattern skin-flap model of diabetic rats in 1999.

Neuromuscular and neuromusculocutaneous flaps in the rat.

Since the introduction of flaps based on the vascular structures of the cutaneous nerves, these have gained increasing popularity in reconstructive surgery. The purpose of this study is to describe a new concept in which the flap is supplied solely by the intrinsic vasculature of a motor nerve. A total of 94 Wistar rats weighing 200-250 g were used in this experiment, which was divided into three sections.

Unique superiority of microsurgical repair technique with its functional and aesthetic outcomes in ring avulsion injuries.

Although ring avulsion injuries are not common, when they do occur their management is still a challenging problem in reconstructive surgery. In this report, we present our microsurgical experiences with Kay's class III and IV ring avulsion injuries. A total of six patients with ring avulsion injuries were operated on between 2000 and 2004.

Is it possible to increase the survival of the transverse rectus abdominis musculocutaneous flap following previous abdominoplasty using a delay procedure? An experimental study in the rat.

Background: Although, because of the disruption of perforators, abdominoplasty has been suggested as a major contraindication for patients undergoing autologous breast reconstruction with the transverse rectus abdominis musculocutaneous (TRAM) flap, many researchers encourage the search for a means of improving the survival of the skin paddle of the flap in patients who have undergone previous abdominoplasty. In this study, the effect of the surgical delay phenomenon on the survival of the TRAM flap following abdominoplasty was investigated.

Methods: Thirty adult Wistar rats were used: the control group (n = 6), the short-term group (n = 12), and the long-term group (n = 12).

Effect of systemic creatine monohydrate supplementation on denervated muscle during reinnervation: experimental study in the rat.

The purpose of this experimental study was to evaluate possible upgrading effects of systemic creatine monohydrate administration on the reinnervation of denervated muscle. At the same time, the protective effect of the agent on denervated muscle until ultimate reinnervation after nerve repair was quantified. The functional outcome of muscle reinnervation after creatine monohydrate application was compared with a control group.

Rationale for reconstruction of large scalp defects using the anterolateral thigh flap: structural and aesthetic outcomes.

The advent of free tissue transfer has provided multiple options that allow preservation and maintain both the structural and aesthetic status of the scalp. Since the first report of the anterolateral thigh flap in 1984, it has become one of the most commonly used flaps for the reconstruction of various soft-tissue defects. Eleven free anterolateral thigh flaps were used to reconstruct soft-tissue defects of different regions of the scalp.

Open guide suture technique for safe microvascular anastomosis.

Despite the evident advances in microsurgery, anastomosis of small vessels or anastomosis of vessels having size discrepancy, remains one of the most precise and technically demanding issues in replantation surgery and free tissue transfer procedure. The patency of the vascular anastomosis is critical and essential for a successful outcome. In this study, a microvascular anastomosing technique called open guide suture technique is introduced.

Simultaneous bilateral microvascular tissue transfer for soft-tissue defects of the lower extremities in pyoderma gangrenosum.

Pyoderma gangrenosum is a necrotizing skin disease of unknown etiology. The lesions are painful and occur mostly on the lower extremities, either single or multiple, but can appear in any region of the body. The authors report a case of pyoderma gangrenosum involving bilateral skin lesions over the anterior surface of the legs in a 13-year-old male patient.

Experiences with microsurgical tissue transfers in elderly patients.

The combination of advances in microsurgery and the improvement of anesthetic management with increased understanding of the physiology of preoperative and postoperative care has significantly raised the upper age limit for free-flap transfer in elderly patients. Despite pessimistic opinions regarding elderly patients who have poor recovery potential and decreased physiological reserves, the unique feature of free-tissue transfer is that it allows the transfer of well-vascularized tissue to defects in a single-stage procedure, and leads to improved quality of life. In this report, a retrospective analysis of 55 patients aged 50 and older who underwent microsurgical tissue transfer is presented.

The penile flap in the rat: description and autotransplantation.

Considering both its unique structural and functional properties, the reconstruction of the penis is still a challenging problem in reconstructive surgery. Reconstruction may be required in many situations, including traumas, congenital abnormalities, and female-to-male transsexual surgery. Currently, the only natural reconstructive method for the penis is its microvascular reattachment in amputation cases.

A rare and serious complication of the radial forearm flap donor site: osteomyelitis of the radius.

Although the radial forearm flap has become a workhorse for the reconstructive surgeon, it has some known disadvantages, especially relating to donor area complications. The authors present a serious but rare complication of the radial forearm donor site. Osteomyelitis of the radius at the flap donor site was observed in a 48-year-old man 5 weeks after flap surgery.

Flow-through, functioning, free musculocutaneous flap transfer for restoration of a mangled extremity.

Reconstructing a mangled extremity requires careful, complete examination of the functional and structural status of the injured part. Although the vascular status of the injured extremity is a priority, simultaneous reconstruction of skeletal, vascular, and neuromuscular structures should be considered in a combined approach. The purpose of this study was to describe a one-stage reconstruction of both soft-tissue coverage and revascularization for a lower extremity, along with functional restoration of an anterior lower leg.

Effects of insulin-dependent diabetes mellitus on perforator-based flaps in streptozotocin diabetic rats.

The purpose of this study was to investigate the effects of insulin-dependent diabetes mellitus (IDDM) on the viability of perforator-based flaps (pbf) in diabetic rats. Random-pattern flaps were also used as a control flap group. Wistar Albino rats, female, n = 60, were used.

Reliability of free-flap coverage in diabetic foot ulcers.

As microsurgery advances, microsurgical free-tissue transfers have become the reconstructive method of choice over staged or primary amputation, and enabling independent ambulation in difficult lower-extremity wounds. In this report, we present our experiences with free-tissue transfer for the reconstruction of soft-tissue defects in 13 diabetic foot ulcers. Following radical debridement, soft-tissue reconstruction was achieved in the following ways: anterolateral thigh fasciocutaneous flap in 5 patients, radial forearm fasciocutaneous flap in 3 patients, lateral arm fasciocutaneous flap in 1 patient, gracilis musculocutaneous flap in 1 patient, tensor fascia latae flap in 1 patient, deep inferior epigastric perforator flap in 1 patient, and a parascapular flap in the remaining patient.

The use of free anterolateral thigh flap for reconstructing soft tissue defects of the lower extremities.

The goal of soft tissue reconstruction in the lower extremities is to provide a functional and cosmetically acceptable limb. The anterolateral thigh flap has become one of the most popular options for soft tissue defect reconstruction recently because of the large amount of skin available and the reliable and versatile nature of this material. The purpose of this article is to present our experiences with the free anterolateral thigh flap for the reconstruction of soft tissue defects of the lower extremity.

New experimental flap model in the rat: free flow-through epigastric flap.

This study describes a free flow-through flap model in the rat for use in the evaluation of the physiologic and hemodynamic characteristics of this type of flap in clinical practice. The rat is a preferred animal model because it is inexpensive, readily available, and reliable. There is no free flow-through flap model available for laboratory animals, although this model gained popularity in clinical use recently.

Simultaneous reconstruction of large maxillary and mandibular defects with a fibular osteocutaneous flap combined with an anterolateral thigh flap.

This article reports the simultaneous reconstruction of maxillary and mandibular defects caused by a close-range gunshot blast to the face with one fibular osteocutaneous flap combined with an anteroateral fasciocutaneous flap. A fibular osteocutaneous flap was used for both mandibular and maxillary defects, using multiple osteotomies and discarding a central bony segment and an oral floor defect. An anterolateral thigh flap was used to cover a three-dimensional defect of both the intraoral mucosal region, as well as external skin and soft tissue defects, including some on the upper and lower lips.
