RESUMEN

PURPOSE: To compare the 20-year outcomes of coronary artery grafting (CABG) using radial artery (RA) grafts (free and I-composite) and internal thoracic artery (ITA) grafts. METHODS: Long-term graft patency was evaluated in patients who underwent isolated CABG between August, 1996 and January, 2022. The long-term graft patency of free RA grafts, I-composite ITA-RA grafts, and saphenous vein (SV) grafts were compared. RESULTS: The RA was used as a coronary bypass conduit in 111 of the 246 patients enrolled in this study. The RA patency after 10 and 20 years was 94.2% and 76.6%, respectively. Landmark analysis showed that although graft patency for up to 10 years did not differ between the RA and ITA grafts (hazard ratio = 0.87; P = 0.8), patency of the ITA grafts was better from 10 to 20 years post-surgery (hazard ratio = 0.19; P = 0.013). The 20-year graft patency of the I-composite RA grafts was better than that of the free RA grafts (80.0% vs. 72.4%; P = 0.029), but not significantly different from that of the ITA grafts (80.0% vs. 90.7%; P = 0.24). CONCLUSIONS: The 20-year patency of the I-composite ITA-RA graft was better than that of the free RA graft; therefore, the I-composite graft may be an effective conduit for CABG.

RESUMEN

OBJECTIVES: Synthetic bone substitutes which can be adapted preoperatively and patient specific may be helpful in various bony defects in the field of oral- and maxillofacial surgery. For this purpose, composite grafts made of self-setting and oil-based calcium phosphate cement (CPC) pastes, which were reinforced with 3D-printed polycaprolactone (PCL) fiber mats were manufactured. MATERIALS AND METHODS: Bone defect models were acquired using patient data from real defect situations of patients from our clinic. Using a mirror imaging technique, templates of the defect situation were fabricated via a commercially available 3D-printing system. The composite grafts were assembled layer by layer, aligned on top of these templates and fitted into the defect situation. Besides, PCL-reinforced CPC samples were evaluated regarding their structural and mechanical properties via X-ray diffraction (XRD), infrared (IR) spectroscopy, scanning electron microscopy (SEM), and 3-point-bending testing. RESULTS: The process sequence including data acquisition, template fabrication, and manufacturing of patient specific implants proved to be accurate and uncomplicated. The individual implants consisting mainly of hydroxyapatite and tetracalcium phosphate displayed good processability and a high precision of fit. The mechanical properties of the CPC cements in terms of maximum force and stress load to material fatigue were not negatively affected by the PCL fiber reinforcement, whereas clinical handling properties increased remarkably. CONCLUSION: PCL fiber reinforcement of CPC cements enables the production of very freely modelable three-dimensional implants with adequate chemical and mechanical properties for bone replacement applications. CLINICAL RELEVANCE: The complex bone morphology in the region of the facial skull often poses a great challenge for a sufficient reconstruction of bony defects. A full-fledged bone replacement here often requires the replication of filigree three-dimensional structures partly without support from the surrounding tissue. With regard to this problem, the combination of smooth 3D-printed fiber mats and oil-based CPC pastes represents a promising method for fabricating patient specific degradable implants for the treatment of various craniofacial bone defects.

RESUMEN

Introduction The aim of this study was to explore the outcomes of composite grafts in fingertip amputations in children as well as the contributing factors that may affect outcomes. Methods Literature search was conducted across six databases in March 2022 to select studies on the use of composite grafts on fingertip amputations in the pediatric population. Results Twelve articles with 735 composite grafts were identified for review. Most fingertip injuries occurred in the less than 5-year age group and were due to crush type injuries. In studies that reported "complete" graft take as a separate outcome measure, 17.3% of fingertips with this result were observed. In the studies that reported "complete" and "partial" graft take together as an outcome measure, 81.6% of fingertips achieved this outcome. A lower proportion of failed graft take was observed in more distal fingertip amputations. Infection (3.8%) and nail abnormalities (3.4%) were the most common complications following composite grafting. Conclusion Composite grafting can be considered as a useful method of treatment in this population. Clinicians should be aware of the potential complications following this method of treatment such as infection and nail abnormalities. More proximal fingertip amputations may warrant other surgical interventions (beyond Level II on the modified Ishikawa/Ishikawa classification). Significant heterogeneity was observed within the studies, mainly due to lack of standardization in assessment and reporting of outcomes.

RESUMEN

OBJECTIVE: Ossiculoplasty is a surgical procedure that recreates sound transmission of the middle ear in conductive hearing loss. Various materials have been used for ossicular reconstruction, but the most ideal material for ossiculoplasty remains controversial. The purpose of this study was to introduce a novel method of autologous ossiculoplasty, bone-cartilage composite graft (BCCG) and to compare its surgical results with different types of ossiculoplastic prostheses. STUDY DESIGN: A retrospective study was performed in a tertiary referral centre. METHODS: Data of 275 patients who received ossiculoplasty using the three different materials of BCCG, Polycel® and titanium were analysed according to type of ossiculoplasty: partial or total ossicular replacement prosthesis (PORP or TORP). Hearing results, complication rates and clinical parameters including age, sex, past history, preoperative diagnosis and surgery type were compared among different groups. RESULTS: Ossiculoplasty with BCCG showed satisfactory hearing outcomes and the lowest complication rate among the three different materials. In particular, its extrusion rate was 0%. CONCLUSION: We propose that the BCCG technique is a useful alternative method for ossiculoplasty, with proper patient selection.

RESUMEN

Vascularized composite allograft (VCA) transplantation is a medically acceptable treatment for the reconstruction of major tissue loss. The advent of VCA transplantation has spurred regulatory and policy development in the United States to address the multiple clinical, ethical and legal issues that must be considered for the practice of VCA donation and transplantation to develop within the existing framework of public trust and transparency vital to the success of donation and transplantation.

RESUMEN

BACKGROUND: Full-thickness skin grafts (FTSGs) are a common repair option on the external ear, but there are few large case series examining graft sublocations, dimensions, and outcomes. OBJECTIVE: We sought to report our experience with FTSGs for repair of postsurgical defects of the external ear. METHODS: We conducted a retrospective review of all FTSGs on the ear performed by 2 surgeons (J. C., 2000-2014; B. C. L., 2007-2014) after clearance by Mohs micrographic surgery at a single institution. RESULTS: A total of 1519 FTSGs on the ear were performed between June 2000 and March 2014. The most common sublocations were the superior helix (38.8%), the crura of the antihelix or scapha (18.9%), and the back of ear/back of helix (15.4%). The overall complication rate was 1.6%, and the most common complication was graft failure (1.2%). LIMITATIONS: Data were collected retrospectively from a single institution. Follow-up beyond 3 months was limited. A standardized assessment tool for aesthetic outcomes was not performed. CONCLUSION: By taking advantage of predictable "pincushioning" and combining with local flaps or cartilage grafts, FTSGs can provide more volumetric replacement than previously described. They reliably preserve the height and complex topography of the ear with a low complication rate.

RESUMEN

OBJECTIVE: This study aimed to present a case of a successful re-implantation of an amputated auricle following a human bite using the Baudet technique. METHODS: Case report and review of the literature. RESULTS: The patient had a very satisfactory postoperative result in terms of appearance and function of the reattached auricle. Cartilage loss was minimal. CONCLUSION: Reattachment of an amputated auricle as a composite graft following a traumatic human bite is feasible. The Baudet technique is a simple alternative that avoids the complexity of microsurgical anastomosis while improving upon the high failure rate associated with simple reattachment.

RESUMEN

BACKGROUND: Internal mammary artery (IMA) grafts provide equal or superior graft patency compared to other conduits. The IMA length limits extensive myocardial revascularisation with IMA grafts alone. This study aimed to determine the results of lengthening free IMAs with a short proximal segment of saphenous vein (SV) to enable more extensive myocardial revascularisation. METHODS: Patients (n=92) who underwent end-to-end composite SV-IMA grafts were followed up through cardiology and death register databases. RESULTS: The mean patient age was 57.5 years and median follow up 10.9 years. There was no perioperative mortality and 10-year survival was 89.6%. Thirty-one patients (34%) underwent repeat angiography at a median of 2.8 years postoperatively. The 10-year freedom from angiography showing SV segment occlusion was 89% with a median time to angiography of 2.3 years (nine patients). The number of distal anastomoses was the only independent predictor of SV segment occlusion HR per anastomosis=0.26 (p=0.01). In five sequential grafts to the circumflex and right coronary systems, the IMA portion of the graft remained patent following SV segment occlusion. CONCLUSIONS: Graft patency is improved by a greater number of coronary artery anastomoses.

RESUMEN

INTRODUCTION: Reconstruction of the loss of transfixing substance from the nose wing is one of the most difficult procedures in facial plastic surgery. We propose a new technique consisting of a composite graft of the controlateral nostril among patients having an asymmetry of the nostrils. PATIENTS AND METHODS: A clinical study was carried out on three patients who had undergone a composite nasal graft. The graft was harvested from the nostril controlateral to the nasal defect then placed at the level of the previously prepared affected nostril. RESULTS: Three patients aged 27, 37 and 39years respectively received a controlateral nasal composite graft for the treatment of transfixing substance loss of the nose wing of less than 1cm. In all three cases, the result was judged to be very satisfactory by the surgeon and by all the patients. CONCLUSION: The controlateral nasal composite graft is a straightforward, quick and reliable technique to treat small losses of transfixing substance from the nose wing. However, because of an uncertain cicatricial ransom of the donor site, this technique must be compared to the auricular composite graft that is the technique of reference.

RESUMEN

Right ventricular outflow tract reconstruction is repeatedly required after the Rastelli procedure. However, standard right ventricular outflow tract reconstruction using direct anastomosis on the posterior right ventricular outflow tract wall is unfeasible in cases with severe calcification. Herein, we present a novel technique called the "lantern procedure," which can fix the prosthetic pulmonary valve without anastomosis to the calcified right ventricular outflow tract wall.

RESUMEN

OBJECTIVES: Since 2000, we anastomosed the saphenous vein graft to the right coronary artery system using the stump of the right internal thoracic artery as inflow. The long-term results of patients where the right coronary artery was grafted with the right internal thoracic artery or the ascending aorta as saphenous vein inflow has not been reported. METHODS: From 2000 to 2018, 699 consecutive patients had right internal thoracic artery elongated with saphenous vein (I-graft group, n = 358, 51.2%) or saphenous vein from the aorta (Ao-graft group, n = 341, 48.8%) on right coronary artery system. Inclusion criteria were age ≤75 years, bilateral internal thoracic arteries as a Y graft on the left system (three-vessel disease, n = 603, 86.3%) or as a left internal thoracic artery on left anterior descending and right internal thoracic artery elongated with saphenous vein on the right coronary artery system (two-vessel disease, n = 96, 13.7%), only 1 saphenous vein per patient. Propensity-matching identified 272 patients per group. One-hundred and twenty-two patients underwent coronary computed tomographic angiography to asses grafts patency after a median follow-up of 88 (65-93) months. RESULTS: In the paired samples, there was no difference in the early outcome. Ten-year survival and freedom from death, non-fatal acute myocardial infarction and repeat revascularization were higher in I-graft group: 90.6 [standard error (SE): 2.0] vs 78.2 (SE: 5.3), P = 0.0266, and 85.2 (SE: 2.4) vs 69.9 (SE: 5.3), P = 0.0179. Saphenous vein graft, at a long-time follow-up, showed a higher patency rate (81.6% (SE: 7.0) vs 50.7% (SE: 7.9), P < 0.0001) and a smaller internal lumen diameter (2.7, standard deviation: 0.4 vs 3.4, standard deviation: 0.6 mm, P < 0.0001) when right internal thoracic artery was the inflow. CONCLUSIONS: Grafting the right coronary artery with saphenous vein may entail higher patency rate and better outcome when the inflow is the right internal thoracic artery than when is the ascending aorta. Prospective randomized data are needed to test this hypothesis.

RESUMEN

INTRODUCTION: The use of biological graft in laparoscopic inguinal hernia repair (LIHR) has been controversial, and there is a lack of high-level evidence to confirm the value of biological graft in LIHR. The purpose of this study is to evaluate the effectiveness of a novel composite biologics in LIHR. METHODS: A multicenter, single-blinded, randomized controlled clinical trial was designed. Fifty patients with unilateral primary inguinal hernia were randomly assigned to the experimental and control group (1:1). The experimental group was repaired with a non-crosslinked composite extracellular matrix from porcine urinary bladder matrix and small intestinal submucosa (UBM/SIS). The control group was repaired with a lightweight, large-pore, synthetic mesh. The primary endpoint was the effectiveness rate of hernia repair. RESULTS: The patients were followed up for four years. No significant difference was found between the experimental group and the control group in the effective rate of hernia repair (24/24[100%] vs 21/22[95.45%], RR, 0.4667; 95%CI, 0.3294-2.304; P = 0.4783). There was no fever, seroma, infection, groin pain, foreign body discomfort or recurrence in the experimental group during the follow-up. In the control group, there were 2 cases of seroma 14 days after operation, 1 case of groin discomfort 60 days after operation and one case of recurrence 410 days after surgery. CONCLUSION: Compared with the lightweight synthetic mesh, the novel UBM/SIS graft has comparable short-term and medium-term effectiveness in LIHR, and the incidence of postoperative complications such as seroma groin discomfort is lower.

RESUMEN

Reconstruction of vermillion defects of the lower lip requires careful consideration of functional and aesthetic aspects. Traditionally, various local flap methods involving tissue advancement from the corner of the mouth, lateral chin, and medial cheek have been commonly employed to fill lower lip defects. However, these approaches have inherent limitations, which include technical complexity, disruption of the orbicularis oris muscle, lip tightening, microstomia, and visible scarring. To overcome these limitations, we employed a free myomucosal composite graft from the lower lip to reconstruct small to medium vermilion defects. Our technique is based on a simple and reproducible surgical approach that facilitates natural volume rearrangement of tissues. Moreover, this method enables precise inset and tension-free repair, prevents lip tightening, and offers excellent aesthetic outcomes with no vertical scarring and appropriate color matching with surrounding tissues.

RESUMEN

Background: Since 2000, we have been grafting the right coronary artery system (RCAs) using the proximal portion of the right internal thoracic artery (RITA) as the inflow of the saphenous vein graft (SVG) to increase the number of patients undergoing beating heart complete myocardial revascularization. Methods: From 2000 to 2022, 928 consecutive patients underwent SVG on the RCAs. In 546 patients (58.8%), the inflow was the RITA (I-graft group), and in 382 patients (41.2%), the inflow was the aorta (Ao-graft group). The inclusion criteria were age ≤75 years, ejection fraction >35%, only one SVG per patient, bilateral internal thoracic arteries as a Y-graft on the left system (three-vessel disease, n = 817, 88.0%) or left internal thoracic artery on the left anterior descending artery and RITA + SVG on the RCAs (two-vessel disease, n = 111, 12.0%). Propensity matching identified 306 patients per group. After a median follow-up of 8 (5-10) years, graft patency was assessed by coronary computed tomographic angiography in 132 patients (64 in the I-graft group and 68 in the Ao-graft group). Results: Early results were similar in both groups. The I-graft group had higher 10-year survival and freedom from main adverse cardiac events (90.0 ± 2.0 vs. 80.6 ± 3.8, p = 0.0162, and 81.3 ± 2.7 vs. 64.7 ± 5.6, p = 0.0206, respectively). When RITA was the inflow, SVG had a higher estimated 10-year patency rate (82.8% ± 6.5 vs. 58.8% ± 7.4, p = 0.0026) and a smaller inner lumen diameter (2.7 ± 0.4 vs. 3.4 ± 0.6 mm, p < 0.0001). Conclusion: When the inflow is the RITA, SVG grafted to the RCAs (I-graft) may result in a higher patency rate and better outcome than when the inflow is the ascending aorta (Ao-graft). The continuous supply of nitric oxide by RITA may be the cause of the higher patency rate of the I-graft, which can behave like an arterial conduit.

RESUMEN

Composite graft is a useful tool for the reconstruction of specific facial aesthetic subunits with a single surgical stage. This technique, when successful, gives optimal results in the reconstruction of small defects of nose, ear, eyelid and lips. The aim of this work is to optimize the attachment of composite grafts in the reconstruction of small complex facial defects by combining it with Fluorescent Light Energy (FLE) during the healing process of the graft. The beneficial effects of photobiomodulation (PBM) on wound healing might be attributed to anti-inflammatory signaling, cell proliferation, protein synthesis, and decreased bacterial infection. We previously experienced rewarding achievements using Photonic energy in the treatment of burns, non-healing wounds and pathological scars. Therefore, we chose to exploit the potential of bioluminescent energy to maximize aesthetical and functional results, enhancing the formation of new vascular connections and modulating both inflammatory and scarring processes. From the 2nd postoperative day, the patients were locally treated with 5 FLE sessions every (48/72 h) 2 or 3 days. We evaluated results in terms of time for engraftment, quality of the scarring, infective complications and morbidity of the donor site. Graft survival is subject to many factors, both local and systemic. To overcome these issues, various methods have been studied and described. We here report the successful reconstruction of full-thickness defects of the free margin of the nasal alar rim and the central portion of the inferior lip with a composite graft. These results were highly encouraging if compared with the literature. By analyzing our small cohort, we demonstrated how new technologies may push this traditional reconstructive procedure beyond their old boundaries: overcoming an increased size demand or a potential infective wound environment.

RESUMEN

PURPOSE: Reimplanting the radial artery in the left internal thoracic artery as a composite graft allows total arterial revascularization (TAR) without aortic manipulation. The limitation of this strategy is the length of the radial artery required to reach distal right coronary artery (RCA) branches. Our analysis focuses on the feasibility of this strategy. METHODS: A total of 169 patients underwent TAR using the radial artery in a composite grafting configuration. Length of the radial artery, number of sequential anastomoses, heart size, target location, length of the arm, patient height, body surface area, and flow in the composite graft were prospectively collected. RESULTS: The mean length of the radial artery was 18.02 cm. Patients with a mean length of the radial artery of 15.9 cm needed an extension of the radial artery with another conduit to reach the RCA distal branches. When T-configuration is used, the length of the radial artery should be 0.53 cm per sequential anastomosis to reach the RCA distal branches. CONCLUSIONS: Our study shows that an average length of 18.02 cm of radial artery is needed to reach targets on the RCA distal branches in composite grafting. In T-configuration, we need 0.53 cm more length per anastomosis to achieve TAR.

RESUMEN

Reprojecting the severely damaged nose is a challenging operation fraught with pitfalls. This panel discussion covers 6 fundamental questions answered by 3 surgeons, each with decades of experience. Discussion points include management of the 3 components necessary for successful reconstruction-the soft tissue envelope, the support structure, and the internal lining. The authors also discuss how their practices have changed in the last few years.

RESUMEN

Findings in the present case underscore the potential of sutureless aortic valve utilization in patients with prior prosthetic root replacement, thereby obviating the need for high-risk procedures such as replacing a prosthetic root or reimplanting a coronary artery. A 75-year-old male who had undergone a Bio-Bentall operation with a bioprosthetic Trifecta valve for aortic regurgitation and annuloaortic ectasia eight years prior presented with symptoms of heart failure, notably dyspnoea, attributed to prosthetic valve dysfunction. Although a transcatheter aortic valve implant is often recommended, it was deemed unsuitable in this case due to a history of type B aortic dissection. Aortic valve replacement utilizing a sutureless Perceval valve with a Trifecta cuff as the valve ring was successfully performed through a repeat median sternotomy, which enabled aortic valve replacement via a higher than usual aortotomy with minimal adhesion dissection. Despite the inherent risks associated with a reoperation post-Bentall surgery, the duration of the procedure was notably short, with only 85 minutes required for cardiopulmonary bypass and 51 minutes for aortic clamping, resulting in an overall operating time of 198 minutes, thus highlighting the minimally invasive and safe nature of this approach.
