RESUMO
BACKGROUND: Autologous fat grafting is a helpful supplement to facelift surgery that helps to combat age-related volume loss of facial structures. Despite the widespread prevalence of combined facelift and fat-grafting, significant procedural variation exists between providers. OBJECTIVES: The primary purpose of this systematic review was to study the efficacy and complication rates of facelift with lipofilling compared with facelift alone. METHODS: A systematic review of the Cochrane Library and MEDLINE databases as completed was undertaken to identify all clinical reports of fat grafting combined with facelift surgery based on the following key terms: ("fat grafting" OR "lipotransfer" OR "lipofilling" OR "fat transfer") AND ("facelift" OR "rhytidectomy" OR "SMASectomy" OR "facial rejuvenation"). Data on techniques, outcomes, complications, and patient satisfaction were collected. RESULTS: The systematic review was performed in April 2017. In total, 248 articles were identified for review. After application of exclusion criteria, 15 primary studies were included in this review. Various facelift techniques were reported, including deep-plane or sub-superficial musculoaponeurotic system (SMAS) facelift, SMAS facelift, modified minimal access cranial suspension lift, component facelift, midface lift, SMAS plication, SMAS-stacking/SMASectomy, and SMASectomy. The most common locations of fat graft injection included the nasolabial folds, tear troughs, temporal regions, midface/cheek/malar eminence, marionette groove, lips, and ear lobes. The addition of fat grafting to facelift surgery resulted in significant improvements in facial volume and aesthetic assessments. CONCLUSIONS: Combined facelift and fat grafting is a safe and efficacious means to simultaneously address age-related ptosis and volume loss. Further research is required to validate and improve existing treatment modalities.

BACKGROUND: Postoperative complications are an independent predictor of poor survival across several tumors. However, there is limited literature on the association between postoperative morbidity and long-term survival following total laryngectomy (TL) for cancer. METHODS: We conducted a retrospective review of all TL patients at a single institution from 2008 to 2013. Demographic and clinical data were collected and analyzed, including postsurgical outcomes, which were classified using the Clavien-Dindo system. Multivariable Cox regression analyses were performed to identify factors associated with overall survival (OS) and disease-free survival (DFS). RESULTS: A total of 362 patients were identified. The mean age was 64 years, and the majority of patients were male (81%). The median follow-up interval was 21 months. Fifty-seven percent of patients had received preoperative radiation, and 40% had received preoperative chemotherapy. Fifty-seven percent of patients underwent salvage TL, and 60% underwent advanced reconstruction (45% free flap and 15% pedicled flap). A total of 136 patients (37.6%) developed postoperative complications, 92 (25.4%) of which were major. Multivariable modeling demonstrated that postoperative complications independently predicted shorter OS (hazard ratio [HR], 1.50; 95% CI, 1.16-1.96; P = .002) and DFS (HR, 1.36; 95% CI, 1.05-1.76; P = .021). Other independent negative predictors of OS and DFS included positive lymph node status, preoperative chemotherapy, comorbidity grade, and delayed adjuvant therapy. Severity of complication and reason for TL (salvage vs primary) were not shown to be predictive of OS or DFS. CONCLUSION: Postoperative complications are associated with worse long-term OS and DFS relative to uncomplicated cases. Patient optimization and timely management of postoperative complications may play a critical role in long-term survival.

BACKGROUND: The relationship between surgeon and hospital charges and payments for total shoulder arthroplasty (TSA) has not been well examined. The goal of this study was to report trends and variation in hospital charges and payments compared with surgeon charges and payments for TSA. METHODS: The 5% Medicare sample was used to capture hospital and surgeon charges and payments for TSA from 2005 to 2014. Two values were calculated: (1) the charge multiplier (CM), which is the ratio of hospital to surgeon charges, and (2) the payment multiplier (PM), which is the ratio of hospital to surgeon payments. The year-to-year variation and regional trends in patient demographic characteristics, Charlson Comorbidity Index, length of stay (LOS), CM, and PM were evaluated. RESULTS: The study included 10,563 patients. Per-patient hospital charges increased from $33,836 to $67,177 (99.9% increase), whereas surgeon charges increased from $4284 to $4674 (9.1% increase) (the CM increased from 7.9 to 14.4, P < .0001). Hospital payments increased from $8758 to $14,167 (61.8%), whereas surgeon payments decreased from $1028 to $884 and the PM increased from 8.5 to 16.0 (P < .0001). The LOS decreased significantly (P < .0001), whereas the Charlson Comorbidity Index remained stable. Both the CM (r2 = 0.931) and PM (r2 = 0.9101) were strongly negatively associated with the LOS. CONCLUSIONS: Hospital charges and payments relative to surgeon charges and payments have increased substantially for TSA despite stable patient complexity and a decreasing LOS. These results encourage the need for future studies with detailed cost analyses to identify the reasons for hospital and surgeon financial malalignment.

Pure hair and nail ectodermal dysplasia (PHNED) is a rare disorder that presents with hypotrichosis and nail dystrophy while sparing other ectodermal structures such as teeth and sweat glands. We describe a homozygous novel missense mutation in the HOXC13 gene that resulted in autosomal recessive PHNED in a Hispanic child. The mutation c.812A>G (p.Gln271Arg) is located within the DNA-binding domain of the HOXC13 gene, cosegregates within the family, and is predicted to be maximally damaging. This is the first reported case of a missense HOXC13 mutation resulting in PHNED and the first reported case of PHNED identified in a North American family. Our findings illustrate the critical role of HOXC13 in human hair and nail development.

PURPOSE: Reconstructing defects after resecting soft-tissue sarcoma (STS) can be challenging. The aim of this retrospective study was to analyze the reconstructive outcomes and identify the potential risk factors in patients undergoing reconstruction after excision of lower-extremity STS. METHODS: Patients with lower-extremity STS were included. This database was compiled of patients from a single, large National Cancer Institute-accredited academic hospital. In total, 302 patients were included between January 2016 to January 2022. Univariate and multivariate analyses were performed to calculate odds ratios (ORs) for developing complications for each patient and surgical characteristic. RESULTS: The following factors were independent predictors of any complication: benign pulmonary disease (OR = 4.2; p = 0.02), preoperative radiotherapy (RT; OR = 2.5; p = 0.047), a tumor in the medial thigh (OR = 1.9; p = 0.03), body mass index (BMI) > 30 kg/m2 (OR = 1.05; p = 0.037), and full-thickness skin graft (OR = 5.4; p = 0.01). In the preoperative RT subgroup, reconstructing a defect via undermining and layered closure alone was an independent predictor of dehiscence (OR = 2.1; p = 0.02) and seroma (OR = 3.1; p = 0.02), whereas pedicled flaps (OR = 0.08; p = 0.001) and free flaps (OR = 0.05; p = 0.001) were independent protectors against any complication. CONCLUSION: Information derived from this analysis will assist with accurate preoperative patient counseling, which is crucial for informed decision-making and expectation management in lower-extremity STS. BMI and pulmonary function should be optimized to the extent possible to reduce postoperative complications. Patients treated preoperatively with RT should be reconstructed with a pedicled or free flap to optimize recovery.

Drug-induced movement disorders (DIMDs) are associated with use of dopamine receptor blocking agents (DRBAs), including antipsychotics. The most common forms are drug-induced parkinsonism (DIP), dystonia, akathisia, and tardive dyskinesia (TD). Although rare, neuroleptic malignant syndrome (NMS) is a potentially life-threatening consequence of DRBA exposure. Recommendations for anticholinergic use in patients with DIMDs were developed on the basis of a roundtable discussion with healthcare professionals with extensive expertise in DIMD management, along with a comprehensive literature review. The roundtable agreed that "extrapyramidal symptoms" is a non-specific term that encompasses a range of abnormal movements. As such, it contributes to a misconception that all DIMDs can be treated in the same way, potentially leading to the misuse and overprescribing of anticholinergics. DIMDs are neurobiologically and clinically distinct, with different treatment paradigms and varying levels of evidence for anticholinergic use. Whereas evidence indicates anticholinergics can be effective for DIP and dystonia, they are not recommended for TD, akathisia, or NMS; nor are they supported for preventing DIMDs except in individuals at high risk for acute dystonia. Anticholinergics may induce serious peripheral adverse effects (e.g., urinary retention) and central effects (e.g., impaired cognition), all of which can be highly concerning especially in older adults. Appropriate use of anticholinergics therefore requires careful consideration of the evidence for efficacy (e.g., supportive for DIP but not TD) and the risks for serious adverse events. If used, anticholinergic medications should be prescribed at the lowest effective dose and for limited periods of time. When discontinued, they should be tapered gradually.

BACKGROUND: Transcatheter mitral valve replacement (TMVR) faces anatomical challenges, currently limiting widespread adoption. OBJECTIVES: To describe the natural history and prognosis of patients ineligible for various TMVR devices. METHODS: During a 4-year period (2019-2023) 3 TMVR devices (SAPIEN M3, Intrepid and Alta Valve) became available at a single institution (The Christ Hospital, Cincinnati, OH) in the setting of pivotal clinical trials or early feasibility study. Consenting patients who were deemed ineligible ≥1 of these trials were prospectively studied to capture anatomical reasons for ineligibility, cross-over to alternative mitral valve therapies (surgery or high-risk mitral transcatheter edge to edge repair [M-TEER]), and clinical events. RESULTS: A total of 61 patients (out of 71 consenting patients or 85.9 %) were deemed ineligible for TMVR during the study period. The mean age was 79.2 ± 8.8 years, 65.6 % were female, with elevated surgical risk (median STS 4.3, IQR: 2.7-7.3). The 2 most common anatomical reasons for ineligibility were increased risk of left ventricular outflow tract obstruction (LVOTO) (n = 24, 39.3 %) and annular size (n = 29, 47.5 %). During follow-up (median 277 [162-555] days) there were 7 deaths (11.5 %) and 12 (19.7 %) hospitalizations for heart failure. Management strategies included high-risk M-TEER in 11 patients (1 death [9.0 %], 0 HF hospitalizations [0 %]), surgery in 9 patients (0 deaths, 1 HF hospitalizations [11.1 %]), and medical management in 41 patients (6 deaths [14.6 %], 11 HF hospitalizations [26.8 %]) (p = 0.715 for mortality and p = 0.093 for HF hospitalizations). Residual MR ≥ moderate was 0 %, 50 %, and 100 % for surgery, M-TEER and medical treatment, respectively (p < 0.001). CONCLUSIONS: One third of patients deemed ineligible for TMVR are candidates for high-risk M-TEER or surgery with acceptable morbidity and mortality. Our results have practical implications for patient management.

Although autologous free-flap breast reconstruction is the most durable means of reconstruction, it is unclear how many additional operations are needed to optimize the aesthetic outcome of the reconstructed breast. The present study aimed to determine the average number of elective breast revision procedures performed for aesthetic reasons in patients undergoing unilateral autologous breast reconstruction and to analyze variables associated with undergoing additional procedures. Methods: A retrospective review of all unilateral abdominal-based free-flap breast reconstructions performed from 2000 to 2014 was undertaken at a tertiary academic center. Results: Overall, 1251 patients were included in the analysis. The average number of breast revision procedures was 1.1 ± 0.9, and 903 patients (72.2%) underwent at least one revision procedure. Multiple logistic regression analysis demonstrated that younger age, higher body mass index, and prior oncologic surgery on the reconstructed breast were factors associated with increased likelihood of undergoing a revision procedure. The probability of undergoing at least one revision increased by 4% with every 1-unit (kg/m2) increase in a patient's body mass index. Multiple Poisson regression modeling demonstrated that younger age, prior oncologic surgery on the reconstructed breast, and bipedicle flap reconstruction were significant factors associated with undergoing a greater number of revision procedures. Conclusions: Most patients who undergo unilateral autologous breast reconstruction require at least one additional operation to optimize their breast aesthetic results. Young age and obesity increase the likelihood of undergoing additional operations. These findings can aid reconstructive microsurgeons in counseling patients and establishing patient expectations prior to their undergoing microvascular breast reconstruction.
RESUMO
Background: Transcatheter mitral valve replacement (TMVR) is evolving; however, limitations include severe calcification of the mitral valve leaflets and mitral annular calcification (MAC), which may be associated with incomplete valve expansion. Shockwave intravascular lithotripsy (IVL)-assisted percutaneous mitral valvuloplasty to treat calcific mitral stenosis has been reported. We describe the first human use of IVL-assisted transseptal TMVR with the Intrepid valve to treat a severely calcified mitral valve in a patient with severe stenosis and regurgitation. Methods: An 83-year-old man with rheumatic heart disease and severe MAC (MAC score, 10; calcium volume score, 7756 cm3) presented with combined mitral stenosis and regurgitation (valve area, 1.5 cm2; 3+ mitral regurgitation [MR]) and medically refractory heart failure symptoms and was enrolled into the APOLLO (Transcatheter Mitral Valve Replacement With the Medtronic Intrepid TMVR System in Patients With Severe Symptomatic Mitral Regurgitation) trial of Intrepid valve TMVR. Transseptal implantation of a 48-mm Intrepid valve was facilitated by Shockwave IVL delivered via two 8.0 × 60-mm M5+ balloons placed across the mitral annulus before implantation. Cerebral embolic protection during IVL and valve implant was provided by a Sentinel device and left subclavian balloon occlusion. Results: Despite initial postimplant valve frame deformation and moderate central MR, postdilation achieved valve frame expansion and reduced MR. Echocardiography and computed tomography performed before hospital discharge and at 30 days show progressive valve frame expansion in the anteroposterior dimension, increased valve area, and resolution of MR. Conclusions: Intravascular lithotripsy of severe MAC before self-expanding TMVR may enhance annular compliance, mitigate fibroelastic recoil, and minimize TMVR valve frame deformation. Although promising, further study is required before IVL is considered a routine adjunct for TMVR in severe MAC.
RESUMO
BACKGROUND: This study assessed the clinical utility of near-infrared fluorescence imaging using indocyanine green in off-pump beating heart total endoscopic and robotic-assisted coronary artery bypass using the fluorescence imaging system for the da Vinci Si on a canine model for vessel identification, graft patency, and correlation of graft patency with ultrasound transit-time flow measurement probe. METHODS: Beating heart total endoscopic robotic-assisted coronary artery bypass was performed on eight canine using indocyanine green and fluorescence imaging to identify the internal mammary artery prior to harvesting, the coronary vessel anatomy, and the patency of the beating heart total endoscopic coronary artery bypass anastomosis. Three to four injections of indocyanine green with a dose of 1.25 mg to 2.5 mg were administered per animal. Transit-time flow was measured in each of the dogs. RESULTS: High definition 3D images were obtained. The camera working distance, indocyanine green dosage, internal mammary artery visualization, coronary artery visualization, patency by indocyanine green injection, and patency by transit-time flow were recorded. Six cases were completed successfully, and all demonstrated correlation between indocyanine green measurements of flow, and the transit-time flow measurement. CONCLUSION: Use of near-infrared fluorescence with indocyanine green was feasible in our study, and would be of great benefit during total endoscopic robotic-assisted coronary artery bypass using the fluorescence imaging-capable da Vinci Si system to help identify the internal mammary artery, delineate the coronary anatomy, and also determine patency of the anastomoses. This procedure correlated well with transit-time flow measurement.

BACKGROUND: Advances in optics and instrumentation with the da Vinci S Surgical System have facilitated minimally invasive and robotic cardiac procedures including mitral valve repair and atrial myxoma excision. We report our retrospective data comparing robotically assisted myxoma excision with standard median sternotomy excision. METHODS: Data were collected for cardiac myxoma resection performed between January 2000 and December 2009. The resulting cohort included a total of 57 patients. These patients were grouped into two categories: robotic-assisted (n = 17) surgical procedures and traditional (nonrobotic; n = 40) surgical procedures. Presurgical and surgical risk factors were examined. RESULTS: Univariate analysis comparing the surgical procedure groups and surgical risk factors found a significant difference in 3 of the 14 variables. Cannulation in all patients undergoing robotic-assisted cardiac myxoma excision was performed through cannulating the common femoral artery and vein while cannulation for the traditional procedures was performed using the aorta and atrium except for two patients. For aortic occlusion, 14 of the robotic-assisted cardiac myxoma patients had balloon occlusion and 34 of the traditional cardiac myxoma patients had aortic cross-clamp occlusion. Operating time was significantly shorter for robotic cases (2.7 hours) compared with traditional cases (3.5 hours). CONCLUSION: Robotic excision of atrial myxomas is safe and may be an alternative to traditional open surgery in selected patients.

INTRODUCTION: The objective of this study was to compare Zip and Clozex with a typical closure using a running 3-0 Prolene suture. METHODS: A prospective, randomized, controlled trial was conducted in patients aged 18 years and older undergoing elective orthopaedic surgical procedures between 2019 and 2021. Patients were randomized to undergo skin closure using a running 3-0 Prolene suture, Zip, or Clozex. The length and location of incision, time to close, surgeon satisfaction, and complications were recorded. The Stony Brook Scar Evaluation Scale (SBSES) was used to assess cosmesis at 2 weeks and 3 months postoperatively. Patient satisfaction and adverse events were also recorded. RESULTS: Thirty-two patients were included in the analysis. Suture closure time was longer than Zip (266 vs 123 seconds; P = 0.02) and Clozex (266 vs 91 seconds; P = 0.005). SBSES scores were greater for Clozex at 2 weeks compared with suture (4.09 vs 2.8; P = 0.005). At 3 months, Clozex maintained greater scores compared with suture (3.82 vs 2.85; P = 0.023) and Zip (3.82 vs 3.0; P = 0.046).No differences were observed in patient satisfaction at any time points. DISCUSSION: Although patient satisfaction was similar across groups, wound closure times, SBSES scores, and total cost favor Clozex compared with Prolene suture or Zip.

OBJECTIVES: During congenital heart surgery, the pulmonary valve and root may be placed into the systemic position, yielding a "neoaortic" valve. With the stress of systemic pressure, the pulmonary roots can dilate, creating aneurysms and/or neoaortic insufficiency (neoAI). This report analyzes the early outcomes of patients undergoing neoaortic valve repair incorporating geometric ring annuloplasty. METHODS: Twenty-one patients underwent intended repair at six centers and formed the study cohort. Thirteen had previous Ross procedures, five had arterial switch operations, and three Fontan physiology. Average age was 21.7 ± 12.8 years (mean ± SD), 80% were male, and 11 (55%) had symptomatic heart failure. Preoperative neoAI Grade was 3.1 ± 1.1, and annular diameter was 30.7 ± 6.5â mm. RESULTS: Valve repair was accomplished in 20/21, using geometric annuloplasty rings and leaflet plication (n = 13) and/or nodular release (n = 7). Fourteen had neoaortic aneurysm replacement (13 with root remodeling). Two underwent bicuspid valve repair. Six had pulmonary conduit changes, one insertion of an artificial Nodulus Arantius, and one resection of a subaortic membrane. Ring size averaged 21.9 ± 2.3â mm, and aortic clamp time was 171 ± 54â minutes. No operative mortality or major morbidity occurred, and postoperative hospitalization was 4.3 ± 1.4 days. At discharge, neoAI grade was 0.2 ± 0.4 (P < .0001), and valve mean gradient was ≤20 mm Hg. At average 18.0 ± 9.1 months of follow-up, all patients were asymptomatic with stable valve function. CONCLUSIONS: Neoaortic aneurysms and neoAI are occasionally seen late following Ross, arterial switch, or Fontan procedures. Neoaortic valve repair using geometric ring annuloplasty, leaflet reconstruction, and root remodeling provides a patient-specific approach with favorable early outcomes.

INTRODUCTION: The primary objective of this study was to examine the relationship between vitamin D deficiency and implant-related and medical complications following total shoulder arthroplasty. METHODS: Using the PearlDiver database, patients who underwent total shoulder arthroplasty from 2005 to 2016 with vitamin D deficiency were identified. These were compared to a 3:1 control group matched by age, sex, and presence of a concomitant osteoporosis diagnosis. Primary outcome measures were implant-related complications (loosening, periprosthetic fracture, periprosthetic joint infection, and revision total shoulder arthroplasty) in addition to medical complications within 90 days of surgery. A multivariable logistic regression analysis was utilized to control for patient demographics and comorbidities. RESULTS: One thousand and six hundred and seventy-four patients with vitamin D deficiency were identified and compared to 5022 controls. There was a significantly higher rate of revision total shoulder arthroplasty in the vitamin D deficient patients compared to controls (2.3% versus 0.8%, odds ratio 3.3, p < 0.0001). After controlling for confounding variables, there were no significant differences in any of the remaining implant-related or medical complications with the exception of higher rates of urinary tract infections in patients with vitamin D deficiency. CONCLUSIONS: Vitamin D deficiency is associated with a higher rate of all-cause revision total shoulder arthroplasty but not medical complications compared to controls.Level of evidence: Level III case control study.
RESUMO
Elastic fiber fragmentation (EFF) is a hallmark of aortic valve disease (AVD), and neovascularization has been identified as a late finding related to inflammation. We sought to characterize the relationship between early EFF and aberrant angiogenesis. To examine disease progression, regional anatomy and pathology of aortic valve tissue were assessed using histochemistry, immunohistochemistry, and electron microscopy from early-onset (<40 yo) and late-onset (≥40 yo) non-syndromic AVD specimens. To assess the effects of EFF on early AVD processes, valve tissue from Williams and Marfan syndrome patients was also analyzed. Bicuspid aortic valve was more common in early-onset AVD, and cardiovascular comorbidities were more common in late-onset AVD. Early-onset AVD specimens demonstrated angiogenesis without inflammation or atherosclerosis. A distinct pattern of elastic fiber components surrounded early-onset AVD neovessels, including increased emilin-1 and decreased fibulin-5. Different types of EFF were present in Williams syndrome (WS) and Marfan syndrome (MFS) aortic valves; WS but not MFS aortic valves demonstrated angiogenesis. Aberrant angiogenesis occurs in early-onset AVD in the absence of inflammation, implicating EFF. Elucidation of underlying mechanisms may inform the development of new pharmacologic treatments.
RESUMO
Proteus syndrome is a rare, sporadically occurring hamartomatous disorder with complex multisystem involvement and wide clinical variability. Clinical characteristics include craniofacial abnormalities; asymmetrical overgrowth of the trunk, limbs, and digits; lipomas; and vascular malformations. Cystic lung disease is noted in approximately 10 per cent of patients. These cystic malformations may lead to cystic pulmonary emphysema, which may cause significant morbidity for the patient. We describe the case of a 27-year-old woman with known Proteus syndrome who developed acute on chronic respiratory failure. Subsequent CT scan of the chest was significant for extensive bullous disease with nearly complete replacement of the right lung tissue. Our operative management and the patient's clinical course are described.

OBJECTIVES: Calcific aortic valve disease (CAVD) is a progressive disease ranging from aortic valve (AoV) sclerosis to AoV stenosis (AS), characterised by severe calcification with impaired leaflet function. Due to the lack of early symptoms, the pathological progression towards valve dysfunction is poorly understood. The early patterns of AoV calcification and altered extracellular matrix (ECM) organisation were analysed in individuals postmortem without clinical AS compared with clinical AS. METHODS: Histological patterns of calcification and ECM organisation in postmortem AoV leaflets without clinical AS obtained from a tissue repository and surgical specimens obtained from individuals with clinical AS were compared with in vivo imaging prior to transcatheter AoV implantation. RESULTS: AoV calcification was detected in all samples from individuals >50 years old, with severity increasing with age, independent of known CAVD risk factors. Two distinct types of calcification were identified: 'Intrinsic', primarily found at the leaflet hinge of postmortem leaflets, accompanied by abnormal collagen and proteoglycan deposition; and 'Nodular', extending from the middle to the tip regions in more severely affected postmortem leaflets and surgical specimens, associated with increased elastin fragmentation and loss of elastin integrity. Even in the absence of increased thickening, abnormalities in ECM composition were observed in postmortem leaflets without clinical AS and worsen in clinical AS. CONCLUSIONS: Two distinct phenotypes of AoV calcification are apparent. While the 'nodular' form is recognised on in vivo imaging and is present with CAVD and valve dysfunction, it is unclear if the 'intrinsic' form is pathological or detected on in vivo imaging.

Advances in magnetic resonance (MR) imaging over the past 2 decades have led to MR becoming an increasingly attractive imaging modality. With the growing number of patients treated with permanent implanted or temporary cardiovascular devices, it is becoming ever more important to clarify safety issues in regard to the performance of MR examinations in patients with these devices. Extensive, although not complete, ex vivo, animal, and clinical data are available from which to generate recommendations regarding the safe performance of MR examination in patients with cardiovascular devices, as well as to ascertain caveats and contraindications regarding MR examination for such patients. Safe MR imaging involves a careful initial patient screening, accurate determination of the permanent implanted or temporary cardiovascular device and its properties, a thoughtful analysis of the risks and benefits of performing the examination at that time, and, when indicated, appropriate physician management and supervision.

OBJECTIVE: Lymphatic complications, such as lymphocutaneous fistula (LF) and lymphocele, are relatively uncommon after vascular procedures, but their treatment represents a serious challenge. Vacuum assisted closure (VAC) therapy has been reported to be an effective therapeutic option for LF, but the effectiveness of VAC therapy for lymphoceles is unclear. METHODS: For LF, we apply the VAC directly to the skin defect after extending it to achieve a clean wound of at least one inch in length. To treat lymphocele, we convert the lymphocele to a LF in a sterile fashion by making a one inch incision in the overlying skin and applying the VAC. The setting was a community teaching hospital. We used 10 patients that we treated with VAC therapy for LF (n = 4) and lymphoceles (n = 6). RESULTS: Duration of in-patient stay, duration of in-patient VAC treatment, duration of out-patient VAC treatment, total duration of VAC treatment. The median duration of in-patient stay was 4 (range, 0-18) days, the median duration of in-patient VAC treatment was 1 (range, 0-5) days, the median duration of out-patient VAC treatment was 16 (range, 7-28) days), and the median total duration of VAC therapy was 18 (range, 13-29) days. Successful wound healing was achieved in all patients with no recurrence after VAC removal. VAC therapy for treatment of both LFs and lymphoceles resulted in early control of drainage, rapid wound closure, and short hospital stays. CONCLUSION: Our results suggest that VAC therapy is a convenient and effective therapeutic option for both LFs and lymphoceles.
