Acute limb ischemia following perineal reconstruction in lithotomy position: take-home message for plastic surgeons

Despite the extensive use of lithotomy position in several plastic surgery procedures, most reports regarding the related incidence of complications are presented in the urologic, gynecologic, and anesthesiologic fields. We present the case of a 54-year-old male patient. polytrauma patient who underwent internal iliac artery embolization leading to extensive gluteal necrosis requiring: debridement, abdominoperineal resection and composite anterolateral thigh flap reconstruction with prolonged lithotomy position. The patient presented lower limb ischemia briefly after surgical theater. A computed tomography scan revealed the obstruction of the left superficial femoral artery requiring emergency revascularization. Arterial thrombosis is a potentially devastating complication and plastic surgeons should be aware of the possible dangers when performing surgeries in prolonged lithotomy position. Preoperative detection of patients at high risks for developing complications should be performed in order to implement preventive measures and avoid potentially life-threatening sequelae.

Abdominal-based adipocutaneous advancement flap for reconstructing inguinal defects with contraindications to standard reconstructive approaches: a simple and safe salvage reconstructive option

Background@#Groin wounds occurring after vascular surgical site infection, oncologic resection, or occasionally orthopedic surgery and trauma may represent a surgical challenge. Reconstruction of these defects by the usual workhorse flaps may be contraindicated following previous surgery and in patients with lower limb lymphedema or extreme morbidity. @*Methods@#This study included 15 consecutive patients presenting with inguinal wounds after vascular or general surgery that required debridement and soft tissue coverage. All cases had absolute or relative contraindications to conventional reconstructive techniques, including a compromised deep femoral artery network, limb lymphedema, scarring of potential flap harvesting sites, or poor overall condition. Abdominal adipocutaneous excess enabled the performance of adipocutaneous advancement flaps in an abdominoplasty-like fashion. Immediate and long-term outcomes were analyzed. @*Results@#Soft tissue coverage was effective in all cases. Two patients required re-intervention due to flap-related complications (venous congestion and partial flap necrosis). All patients fully recovered over a mean±standard deviation follow-up of 2.4±1.5 years. @*Conclusions@#Abdominal flaps can be an effective and simple alternative technique for inguinal coverage with reproducible outcomes. In our experience, the main indications are a compromised deep femoral artery network and poor thigh tissue quality. Relative contraindications, such as previous open abdominal surgery, should be considered.

Sensory assessment of meshed skin grafts over free gracilis muscle flaps without nerve coaptation for lower extremity reconstruction

Background@#Little is known about the sensate recovery of skin grafts over free non-neurotized muscle flaps. The aim of this study was to evaluate the sensitivity of free gracilis muscle flaps and meshed skin grafts without nerve coaptation. @*Methods@#Thirteen consecutive patients with a median age of 55 years (range, 21–70 years) who underwent lower extremity reconstruction between September 2014 and October 2016 were included. Complications, flap contour, skin perception, and sensate recovery were assessed. @*Results@#All flaps survived completely. In one patient, wound dehiscence and infection occurred 1 month after surgery. After a median follow-up of 14 months (range, 10–51 months), a satisfactory contour and skin perception were achieved. The Semmes-Weinstein (SW) monofilament test (154.8±22 g) and static two-point discrimination (2-PD) (12.6±0.7 mm) showed intermediate recovery compared to the surrounding site (41% and 76%, respectively). There was an intermediate correlation between flap size and sensate recovery (2-PD: r=0.27, P=0.36; SW test: r=0.45, P=0.12). Vibration sensation recovered to 60%, whereas thermal sensation remained poor (19% at 5°C and 25% at 25°C). @*Conclusions@#Finer sensation could be partially restored. However, thermal sensation remained poor.

Association of the Lipoprotein Lipase S447X and Neuropeptide Y Leu7Pro Genetic Polymorphisms with the Lipid Profiles of Individuals with and without Evidence of Coronary Artery Disease.

Background: Coronary artery disease (CAD) is a multifactorial disease whose etiogenesis involves a number of environmental, genetic and lifestyle-related factors. Genetic polymorphisms are noteworthy among these factors because they alter gene expression and, thus, the functions of the respective products. Methods: A case-control study was conducted in the Cardiology Institute, with 79 subjects classified as cases with CAD, and 96 subjects as controls without CAD or other disease. In this study, we evaluated the association between the single-nucleotide polymorphisms (SNPs) of S447X and Leu7Pro of the lipoprotein lipase (LPL) and neuropeptide Y (NPY) genes, respectively. Results: No differences were found in the frequencies of LPL SNP between the cases and controls. However, the LPL 447X allele carriers exhibited a near-significant difference in the triglycerides (p=0.086) and higher mean in the HDL-c (p=0.018). NPY polymorphisms proved to be infrequent in this study population, and no significant difference was observed between the groups. Conclusions: Our findings provide further support of the genetic polymorphisms effect on the lipid metabolism control. So, further studies are needed to assess the functional effect of this and other polymorphisms, on LPL and in the NPY activity, and their impact on CAD risk.

The Unresolved Case of Sacral Chordoma: From Misdiagnosis to Challenging Surgery and Medical Therapy Resistance

PURPOSE: A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. METHODS: Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. RESULTS: Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). CONCLUSION: Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center.
