RESUMEN

We report a case of a 64-year-old female who represented two months after pituitary surgery with the novel complication of intermittent disabling post-nasal pulsatile "clicking". Imaging and endoscopic examination showed a residual sella cleft with the tumour capsule and diaphragma cupping against the anterior sella bony defect with each pulsation, causing the clicking. The clicking resolved following second redo surgical endoscopic repair to jail a fat graft within the residual cleft with a central barricade of conchal cartilage graft and onlay standard repair.

RESUMEN

OBJECTIVE: To compare the outcome and complication rate of the platelet-rich plasma applied as a coverage layer and dartos flap layer during primary repair of distal hypospadias. METHODS: A prospective randomized study was carried out comprising 180 boys (age range 12-65 months) from October 2011 to December 2016 at Al-Azhar University Hospitals, Cairo, Egypt. A single surgeon carried out all urethroplasty. Patients were randomly divided into two groups: group A (tubularized incised plate urethroplasty with platelet-rich plasma coverage layer) and group B (ventral dartos flap). Complication rates were compared between two groups. RESULTS: There was a significant difference in the occurrence of complications between the two groups. A total of 36 (20%) complications were recorded in 26 patients, just 12 (13.3%) reported in group A, but 24 (26.7%) complications were reported in group B. Urethrocutaneous fistula was observed in nine patients (10%) in group A, and 12 (13.3%) in group B. Partial glans dehiscence occurred in one patient in group A, and four patients in group B. No patient in group A had a superficial wound infection, compared with six patients in group B. One case of meatal stenosis and urethral stricture was recorded in each group, all of which were managed conservatively. The resultant urinary stream was single and good in 154 patients of both groups. CONCLUSIONS: Platelet-rich plasma sheet might be considered as an alternative coverage layer for distal hypospadias repair, especially in the absence of a healthy layer.

RESUMEN

BACKGROUND: Dilong injection as a medicinal preparation extracted from earthworm in traditional Chinese medicine, is used to activate blood circulation and remove blood stasis. In this research, we aim to investigate its potential effect on random skin flap survival in rat models. MATERIALS AND METHODS: McFarlane flaps were established in 60 male Sprague-Dawley rats randomly divided into two groups: the control group and the Dilong injection group. Diong injection group was injected with the Diong injection (4 mL/kg) once a day for seven days, and the control group was given an equal volume of saline solution. After seven days, flaps were obtained and stained with Hematoxylin and Eosin. Histological examination was done to determine changes in histology such as thickness of granulation tissue, tissue edema, neutrophil infiltration, and the microvascular density (MVD). In addition, immunohistochemical detection was carried out to show vascular endothelial growth factor (VEGF) expression level. RESULTS: Compared with the control group, the Dilong group exhibited more fibroblastic proliferation, thinner neutrophil infiltration with less edema through histological examination. The MVD and the VEGF expression of flaps were significantly higher. The mean superoxide dismutase activity was evidently higher in the Dilong group than in the control group, while the mean MDA level was lower. CONCLUSIONS: According to the comparison made between the two groups for histological and immunohistochemical evaluation, the Dilong injection group has potential effects on the survival of random skin flaps in rat models.

RESUMEN

The objective of the study was to analyse and present the surgical management strategy for major skin flap complications (MSFC) after cochlear implantations. Patients fitted with a titanium-silicone-coated implant of the same kind, operated on between 1994 and 2013 with a standardised procedure (1076 medical charts) were analysed. Analysis aimed to identify and study individuals with skin problems related to the cochlear implant treatment, i.e. requiring surgical treatment in hospital defined as MSFC and focused on incidence, risk factors and treatment of MSFC. MSFC were diagnosed in 1.76 % of patients: 2.06 % of children and 1.35 % of adults, 2.43 % after implantation with a long "C"-shaped incision and 1.28 % after short retroauricular incision. Registered risk factors included head trauma, acute otitis media, poor hygiene in children, and general comorbidities in adults. The primary intervention was dependent on skin complication severity and included revision surgery with wound closure over an implant (52.6 %) and revision surgery with explantation (47.4 %). Revision surgery without explantation was successful in 40 % and the most effective approach was debridement with a two-layer rotational flap. Explantation led to ultimate wound healing in all cases. Major skin flap complications after cochlear implantation are rare, but their treatment is complex and difficult. Revision surgery with resection of infected tissue, formation of a rotational two-layer flap preceded and supplemented by intensive targeted antibiotic therapy can be effective and should be the first treatment option. Spontaneous implant explantation, abscess formation or unsuccessful primary treatment necessitate implant removal as the ultimate solution.

RESUMEN

BACKGROUND: Leeches are a well-recognized treatment for congested tissue. This study reviewed the efficacy of leech therapy for salvage of venous congested flaps and congested replanted or revascularized hand digits over a 2-year period. METHODS: All patients treated with leeches between 1 Oct 2010 and 30 Sep 2012 (two years) at Queen Elizabeth Hospital, Birmingham, UK were included in the study. Details regarding mode of injury requiring reconstruction, surgical procedure, leech therapy duration, subsequent surgery requirement and tissue salvage rates were recorded. RESULTS: Twenty tissues in 18 patients required leeches for tissue congestion over 2 years: 13 men and 5 women. The mean patient age was 41 years (range 17-79). The defect requiring reconstruction was trauma in 16 cases, following tumour resection in two, and two miscellaneous causes. Thirteen cases had flap reconstruction and seven digits in six patients had hand digit replantations or revascularisation. Thirteen of 20 cases (65%) had successful tissue salvage following leech therapy for congestion (77% in 10 out of 13 flaps, and 43% in 3 of 7 digits). The rate of tissue salvage in pedicled flaps was good 6/6 (100%) and so was in digital revascularizations 2/3 (67%), but poor in digital re-plants 1/4 (25%) and free flaps 0/2 (0%). CONCLUSIONS: Leeches are a helpful tool for congested tissue salvage and in this study, showed a greater survival benefit for pedicled flaps than for free flaps or digital replantations.

RESUMEN

BACKGROUND: Huangqi (Radix astragali) is a traditional Chinese drug, designed to "buqi," which means invigorating vital energy, widely used in clinical settings. We investigated the effect of Huangqi injection on the survival of random skin flaps. METHODS: McFarlane flaps were established in 60 rats divided into two groups. Postoperative celiac injections were given to both groups for 7 days. Huangqi was injected into the test group, and saline was injected into controls. On day 7, tissues were stained with hematoxylin and eosin, immunohistochemically evaluated, and the expression levels of xanthine oxidase determined. RESULT: The mean area of flap survival in the test group was significantly higher compared with the controls. Expression of vascular endothelial growth factor and superoxide dismutase, and microvessel development, were markedly increased in the test group, and the malondialdehyde level was reduced. CONCLUSION: Huangqi injection promotes random skin flap survival.

RESUMEN

BACKGROUND: Hyperbaric oxygen (HBO) is used as an adjunctive therapy for a variety of indications. However, there is a lack of high-quality research evaluating HBO treatment outcomes for different indications available in the current literature. METHODS: We retrospectively reviewed all patients who underwent HBO therapy at a single hyperbaric center from January 2010 to December 2013 using predetermined criteria to analyze successful, improved, or failed treatment outcomes for the following indications: chronic refractory osteomyelitis, diabetic foot ulcer, failed flap or skin graft, osteoradionecrosis, soft tissue radiation necrosis, and multiple coexisting indications. RESULTS: Among the included 181 patients treated with adjunctive HBO at our center, 81.8% had either successful or improved treatment outcomes. A successful or improved outcome was observed in 82.6% of patients treated for chronic refractory osteomyelitis (n = 23), 74.1% for diabetic foot ulcer (n = 27), 75.7% for failed flap or skin graft (n = 33), 95.7% for osteoradionecrosis (n = 23), 88.1% for soft tissue radiation necrosis (n = 42), and 72.4% for multiple coexisting indications (n = 29). Among 4 patients treated for other indications, 100% of the cases were either successful or improved. CONCLUSIONS: This study has provided a comprehensive outcome survey of using HBO for the previously mentioned indications at our center. It supplements the literature with more evidence to support the consideration of HBO in different indications.

RESUMEN

We sought to determine the effect of ischemic preconditioning (IPC) and hirudotherapy (leech therapy) on cutaneous pedicle flaps after they underwent prolonged ischemia (global ischemia) in a mouse model. Twenty cutaneous pedicle flaps were elevated in 20 mice, and the animals were randomized into four groups: sham, control, IPC and leech (5 flaps in each group). Except in the sham group, all flaps were subjected to global ischemia for 5 h via pedicle clamping. The control group did not receive any treatment before or after global ischemia. In the IPC group, global ischemia was preceded by three 10-min episodes of ischemia, each followed by 10 min of reperfusion. In the leech therapy group, after global ischemia, hirudotherapy was performed. Flap survival area and histopathological changes were evaluated on the 10th day after surgery. Flap survival areas were significantly higher in both the IPC and leech groups than in the control group and were significantly higher in the leech group than in the IPC group (p < 0.05). In conclusion IPC and hirudotherapy had definite effects on the survival area of cutaneous pedicle flaps that underwent prolonged ischemia in a mouse model.

RESUMEN

Skin flaps are still a matter of concern among surgeons, as failures can occur leading to flap necrosis. However, low-level laser irradiation has been reported as an effective tool to improve the viability of ischemic flaps, yet its mechanisms of action remain unclear. We investigated the effect of low-level laser irradiation on the viability of random skin flaps in rats and determined COX-2 expression in the flap pedicle. The study animals comprised 24 EPM-1 Wistar rats which were randomly allocated into three equal groups. A cranially based dorsal random skin flap measuring 10 × 4 cm was created in all the animals. In one group, laser irradiation was simulated (sham group), and in the other two groups the animals were irradiated at 12 points with 0.29 J at 20 mW (energy density 10.36 J/cm(2), irradiance 0.71 W/cm(2)), or with 7.3 J at 100 mW (energy density 260.7 J/cm(2), irradiance 3.57 W/cm(2)). These procedures were applied to the cranial half of the flap immediately after surgery and were repeated on days 2 and 5 after surgery. The percentage necrotic area was determined on day 7 after surgery by the paper template method. The immunohistochemical expression of COX-2 in the samples was given scores from 0 to 3. The necrotic area was smaller in group irradiated at 7.3 J compared to sham-treated group and to the group irradiated at 0.29 J (P < 0.05); there was no difference between the sham-treated group and group irradiated at 0.29 J. COX-2 expression was lower in the group irradiated at 7.3 J than in the sham-treated group and the group irradiated at 0.29 J (P < 0.001). Low-level laser therapy was effective in decreasing random skin flap necrosis in rats using a laser energy of 7.30 J per point. Laser irradiation also decreased the expression of COX-2 in the flap pedicle.

RESUMEN

BACKGROUND: There are case reports and small series in the literature relating to the use of medicinal leeches by plastic surgeons; however, larger series from individual units are rare. The aim of this article is to present a comprehensive 4-year case series of the use of medicinal leeches, discuss the current evidence regarding indications, risks, and benefits and highlight the recent updates regarding leech speciation. METHODS: Patients prescribed leeches in a 4-year period (July 2004-2008) were collated from hospital pharmacy records (N = 35). The number of leeches used, demographic, clinical, and microbiological details were retrospectively analyzed. RESULTS: Thirty-five patients were treated with leeches. The age range was 2 to 98 years (mean = 49.3). Leeches were most commonly used for venous congestion in pedicled flaps and replantations. Blood transfusions were necessary in 12 cases (34%) [mean = 2.8 units, range 2-5 units]. Our infection rate was 20% (7/35) including five infections with Aeromonas spp. (14.2%). The proportion of patients becoming infected after leech therapy was significantly greater in the group of patients that did not receive prophylactic antibiotic treatment (Fisher's Exact test P = 0.0005). In total, 14 cases (40%) were salvaged in entirety, in 7 cases 80% or more, in 2 cases 50 to 79%, and in 1 case less than 50% of the tissues were salvaged. In 11 cases (31%), the tissues were totally lost. CONCLUSION: Our study highlights both the benefits and the risks to patients in selected clinical situations and also the potential risks. The routine use of antibiotic prophylaxis is supported. In view of the emerging evidence that Hirudo verbana are now used as standard leech therapy, and the primary pathogen is Aeromonas veronii, until a large prospective multicenter study is published, large series of patients treated with leeches should be reported.

RESUMEN

BACKGROUND: Since the initial work of Jacobson and Suarez in 1960, microsurgery has evolved greatly. In 2009, we reported our clinical experience with 1.9 µm diode laser-assisted vascular microanastomoses (LAMA) for free flap reconstruction. In this report, the ongoing study is now expanded to include 11 additional procedures which were analyzed prospectively with a focus on the duration of the LAMA technique. METHODS: In total, 40 clinical procedures with LAMA have been performed since 2005. Mean follow-up was 3.3 years (range 0.5-5.5 years). Among those, 11 procedures were performed and prospectively analyzed during the period 2008-2009. LAMA was performed with a 1.9 µm diode laser after placement of equidistant stitches. For vessels size <1.5 mm, the following laser parameters were used: spot size 400 µm, five spots for each wall, power 125 mW, arterial/venous fluence 100/90 J/cm(2) (spot duration 1/0.9 seconds). RESULTS: For the last observed 11 procedures, mean occlusion time of the flap arterial and venous anastomoses was 5.4 ± 0.4 and 6.8 ± 0.7 minutes respectively. One anastomosis required a secondary laser application. Arterial and venous patency rates were 100% at the time of surgery. The success rate for the 11 procedures was 100%. The global success rate of the series (97.5%) is discussed and compared with the literature. CONCLUSION: The success rates for reconstructive free flap surgery realized with LAMA appear excellent. Technical innovation will most likely lead to widespread use of the handpiece laser in the operating room.

RESUMEN

INTRODUCTION: Venous convulsion after reconstructive microsurgery procedures is one major complication a surgeon has to deal with. Today, especially in the field of reconstructive microsurgery, medicinal leech therapy enjoys a renaissance. The potential risks such as infections associated with leech therapy are generally underestimated and not sufficiently discussed in literature. METHOD/PATIENTS: We present five male patients with an average age of 47 years. All patients suffered from a trauma incident, which had to be treated as an emergency. Three patients showed, postoperatively, a venous congestion after the reconstructive procedures. Another two patients with flap reconstruction and flap training developed venous problems after 12 and 14 days. In all five cases, the indication was given to use medical leeches (Hirudo medicinalis). In all the patients, a local infection of the injured extremity could be regarded after beginning with the leech treatment. The treatment duration with medical leeches for postoperative venous congestion was an average of 6 days. RESULTS: The reconstructive procedures in all five cases were unfortunately unsuccessful as major local infections were observed. Microbiological analyses showed, in all cases, an infection with Aeromonas hydrophila. CONCLUSION: We recommend making a considered indication for leech therapy, to diagnose wound infections early and to think about prophylactic antibiotics in patients with leech application.

RESUMEN

BACKGROUND: Mandibular reconstruction by means of fibula transplants is the standard therapy for severe bone loss after subtotal mandibulectomy. Venous failure still represents the most common complication in free flap surgery. We present the injection of heparine into the arterial pedicle as modification of the revising both anastomoses in these cases and illustrate the application with a clinical case example. METHODS: Methods consist of immediate revision surgery with clot removal, heparin perfusion by direct injection in the arterial vessel of the pedicle, subsequent high dose low-molecular weight heparin therapy, and leeches. After 6 hours postoperatively, images of early flap recovery show first sings of recovery by fading livid skin color. RESULTS: The application of this technique in a patient with venous thrombosis resulted in the complete recovery of the flap 60 hours postoperatively. Other cases achieved similar success without additional lysis Therapy or revision of the arterial anastomosis. CONCLUSION: Rescue of fibular flaps is possible even in patients with massive thrombosis if surgical revision is done quickly.

RESUMEN

Wound coverage with pedicled (local, regional, or distant) or free flaps is commonplace throughout plastic surgery. However, irrespective of the method of tissue transfer or type of tissue being transferred, inflow and outflow remain key parameters for success. Much has been written detailing complex tissue transfers and delineating arterial and venous anatomy. Despite this, simple venous insufficiency causing venous congestion is common. In experimental models, when arterial inflow is impaired, even mild venous inadequacy affects flap survival. Furthermore, studies have shown that venous congestion is more detrimental to the rate and percentage of flap area surviving than arterial ischemia. Obviously, complete venous occlusion typically requires operative exploration and correction, but many instances occur when venous congestion occurs for reasons other than complete venous thrombosis. Here we detail the basic postoperative "first aid" techniques available to optimize venous drainage. Although these techniques are not a substitute for sound anatomic flap selection, good surgical technique, or re-operation when a significant underlying problem exists, they do offer additional options to improve flap outcomes.

RESUMEN

Proanthocyanidins are potent natural antioxidants which belong to a class of polyphenols. Proanthocyanidin-rich extracts are prepared from grape seeds. The effect of grape seed proanthocyanidin extract (GSPE) on the viability of abdominal skin flaps exposed to warm ischaemia and subsequent reperfusion were studied in 40 male Wistar rats. In the control group (group I; n=20), rats were fed with standard, non-purified rat diet, and the study group received GSPE 100 mgkg(-1) per day 1 week prior to surgery and 1 week following surgery. Abdominal island flaps were elevated in both the groups and subjected to 8h of warm ischaemia, followed by reperfusion. Mean flap survival areas in groups I (control group) and II (treatment group) were calculated to be 58.3%+/-11.72 and 81.0%+/-11.88, respectively. Flap survival on day 7 was significantly higher in group II compared to group I (p<0.01). Histopathological semi-quantitative analysis of the specimens revealed infiltration by polymorphonuclear leucocytes, oedema formation and necrosis in group I, whereas neo-vascularisation and fibrosis were the prominent findings in group II.

RESUMEN

Calciphylaxis or calcific uremic arteriolopathy is characterized by the involvement of the tunica elastica of the reticular or deep subcutaneous dermis, with extravascular and vascular thrombosis calcifications that lead to tissular ischemia. The torso muscles, the lumbar region, and lower limbs are more frequently affected. The pathogenesis is unknown. Calciphylaxis is associated to hyperparathyroidism, chronic renal failure, and diabetes mellitus. The best therapy to date is prevention: early treatment of renal failure, performing a partial parathyroidectomy where necessary, surgical debridement of the necrotic tissue, as well as avoiding the trigger factors such as systemic corticosteroids.
