Plastic surgery and its complications: What we should look?Plastic surgeries are becoming more popular, being performed on a varied type of population and often as office-based procedures. Despite being highly elective procedures, they have risks and complications, which should be reported to patients by the health personnel. The most frequently performed procedures are breast augmentation and body liposuction. The most relevant complications associated with plastic surgery are pulmonary embolism and deep vein thrombosis, which is the leading cause of mortality in this type of surgery. Other complications are local anesthetics intoxication secondary to the use of tumescent solution in body liposuction, inadequate management of perioperative intravenous fluids, mild hypothermia and severe pain after surgery caused by poor postoperative analgesia. It is essential to prevent the described complications, which significantly increase morbidity, mortality and hospital stay. The perioperative measures that have demonstrated effectiveness in reducing perioperative risk are thromboprophylaxis, depending on the thrombotic risk categorization of each patient and the use of adequate concentrations of lidocaine and vasoconstrictor in the tumescent solution. Appropriate temperature monitorization and use of conservation measures in patients with exposure of large body surfaces is also an important issue, as is diligence in intraoperative fluid balance and administration of intravenous multimodal analgesia, adjusted to the magnitude of the surgery. In order to achieve this, proper communication between the surgical team, anesthesiologists and nurses is vital, as it permits implementation of specific measures that permit adequate monitorization, prevention of complications and analgesic management described above.

complex renal artery aneurysm. ex vivo repair and reimplantation introduction: True incidence of renal artery aneurysms is unknown but it has been estimated to be around 1%. They are usually asymptomatic and diagnosed through imaging studies done for other medical reasons. Those that are more than 2 cm in diameter or any aneurysm in pregnant women should be treated because of an elevated risk of rupture. We present a case of a man with a complex 2.5 cm renal artery aneurysm, successfully treated with ex vivo repair and reimplantation by a multidisciplinary team.

Critical appraisal of clinical guidelineObjective: Critical appraisal of the clinical practice guideline (CPG) "Gran Quemado-Extensive Burn Patients"(2007 issue) corresponding to "Garantías Explícitas en Salud-Explicit Health Guarantees" (GES). Material and Methods: The CPG was evaluated using the previously validated AGREE instrument. This instrument evaluates a series of items organized in 6 domains, that capture different dimensions of the guidelines quality comparing the scores obtained with a maximum theoretical score. The CPG was evaluated by three independent and masked authors applying the AGREE instrument. Results: Stratifi ed by domain, in the "scope and purpose" domain there was an 88.9% of compliance; in "stakeholder involvement" 47.9%; in the "rigour of development" 47.6%; in "clarity and presentation" 79.2%; in "applicability" 30.6% and 75% in the "editorial independence" domain; reaching a 44.9% fi nal score of compliance. Conclusions: The score obtained was below 50% of the optimum for a CPG. The detailed analysis by domain makes evident the areas that may be subject of improvement, so as to optimize the applicability of the CPG and therefore guarantee better health care and treatment results for all burn patients benefi ting from the "Explicit Health Guarantees".Key words: Critical appraisal, practice guidelines, quality assessment, evidence based medicine, AGREE, burn.

Double DIEP flap for lower extremities reconstructionintroduction: A soft tissue defect considering the extent, location, depth and involved structures can be a complex task, leading to search for unusual reconstructive alternatives. case report: Puerperal woman, 21 years, previously healthy, admitted for septic shock and skin necrosis of both extremities secondary to purpura fulminans. Escharectomy was performed and the final defect was 27% of total body surface, corresponding to necrotic areas of both superior and lower extremities. Is remarkable the presence of musculocutaneous perforating vessels thrombosis and segmental muscular necrosis in legs and interosseous muscles necrosis in hands. In upper extremity coverage was performed with dermoepidermal grafts. To cover peroneal malleolus and feet dorsum, whereas there were no regional or local alternatives, we realize a double DIEP flap. Flap elevation of bilateral DIEP flap was performed simultaneously for two surgical teams. The patient had no complications and was discharged with complete soft tissue coverage.key words: Double DIEP flap, lower limb reconstruction, microsurgery.
