RESUMO
BACKGROUND: Lentigo maligna melanoma is mainly localized in the head and neck region in elderly patients. Due to its slow horizontal growth, it has a good prognosis compared to other melanoma subtypes, but specific data are rare. OBJECTIVES: The aim of this study was to investigate sentinel lymph node biopsy in lentigo maligna melanoma under local anaesthesia and to discuss the benefit. METHODS: Investigation of patients with lentigo maligna melanoma and tumour thickness ≥1 mm treated at the Department of Dermatology, University Medical Centre Tuebingen, between January 2008 and October 2019. RESULTS: In total, 204 patients (126 SLNB, 78 non-SLNB) with a median age of 75.7 years (SLNB: 73.3 years, non-SLNB: 79.7 years) could be included. Sixteen of 126 (12.7%) sentinel lymph nodes were positive. Five-year overall survival was 87.9% (88.5% SLNB; 87.4% non-SLNB) and 5-year distant metastasis-free survival was 85.8% (85.4% SLNB; 86.7% non-SLNB). There was no significant difference for distant metastasis-free survival (p = 0.861) and overall survival (p = 0.247) between patients with and without sentinel lymph node biopsy. CONCLUSIONS: Sentinel lymph node biopsy in lentigo maligna melanoma under local anaesthesia is a safe and simple method, even in very old patients. However, LMM has a very good 5-year overall survival. In high-risk patients with high tumour thickness and/or ulceration, adjuvant immunotherapy can now be offered without the need to perform this procedure.

BACKGROUND AND OBJECTIVES: Due to frailty, dermatosurgery in the elderly is preferably performed under tumescent local anesthesia, but data is limited. The aim was to evaluate tumescent local anesthesia for skin cancer surgery in the elderly with focus on clinical benefits (treatment processes, pain management) and local postoperative complication risk. PATIENTS AND METHODS: Investigation of patients ≥ 75 years with inpatient head and neck skin cancer surgery under tumescent local anesthesia. RESULTS: 2,940 procedures in 782 patients (mean age 83.3 years) were performed with the aim of complete tumor resection during the inpatient stay. 3.8 (range: 1-20) interventions were done over an average of 4.9 days (range: 1-28). 43.2% did not require any postoperative analgesia. 53.5% received NSAIDs, 3.3% opioids. Infection (13.6%) was the most common local postoperative complication. Surgical intervention due to bleeding was required in 2.8%. None was hemoglobin relevant or life-threatening. Suture dehiscence and necrosis were rare (0.6%). CONCLUSIONS: Tumescent local anesthesia is an effective method for skin cancer surgery in the elderly. By avoiding general anesthesia, treatment processes can be optimized and anesthesiologic risks minimized. Local postoperative complications are still low and well treatable. The long-lasting analgesia results in a reduced need for analgesics and drug interactions.

BACKGROUND: Due to demographic change and increased UV exposure, the number of dermatosurgical procedures in the elderly is increasing. Data on the occurrence of systemic side effects during and after treatment with tumescent local anaesthesia are limited and do not refer to details such as volume and composition of local anaesthetics or epinephrine additive. OBJECTIVES: The aim of this study was to investigate the risk of systemic side effects in elderly patients undergoing skin tumour surgery with tumescent local anaesthesia. METHODS: Investigation of systemic complications in patients (≥75 years) who underwent head and neck skin tumour surgery under tumescent local anaesthesia at the Department of Dermatology, University Medical Centre Tübingen, between October 2018 and March 2020. RESULTS: In total 782 patients (479 males, 303 females) with a mean age of 83.3 years (range: 75.1-102.2 years) could be included. A total of 2940 procedures were performed. Patients were assigned to two groups. The old-old group (≥75-84 years) included 491 patients and the oldest-old group (≥85 years) included 291 patients. The total inpatient stay and thus mean follow-up period was 4.9 days (range 1-28 days). 92.0% (719/782) suffered from pre-existing comorbidities. Systemic complications occurred in 10.2% (80/782; old-olds: 8.6%, oldest-olds: 13.1%). Hypertensive crisis (>180/120 mmHg) requiring intervention (6.7%) that occurred intraoperatively or during the inpatient stay was the most frequent systemic complication. Cardiac arrhythmias occurred postoperatively in 0.8% of cases. No life-threatening complications directly related to tumescent local anaesthesia were found. CONCLUSIONS: Skin tumour surgery in tumescent local anaesthesia for the elderly is safe, and complications caused by general anaesthesia can be avoided. Systemic complications can occur, but are usually mild, are caused by pre-existing diseases and perioperative excitement, and can be rapidly detected and well treated by monitoring. There is no direct correlation of complications to high-tumescent concentrations or volume quantities.

BACKGROUND: Perusal of the literature of cutaneous squamous cell carcinoma (SCC) reveals that the role of the desmoplastic subtype is indistinct. Data on local infiltration and recurrence are inconsistent dependent on surgical technique, histological method, and investigated collective. OBJECTIVE: The aim of the study was to analyze local infiltration and locoregional recurrence of the desmoplastic subtype under a uniform procedure. METHODS AND MATERIALS: Between 2005 and 2015, 320 SCCs were analyzed and histological sections of all tumors were examined. Data collection included locoregional recurrence, metastasis rate, and tumor-specific death. The median follow-up was 36.5 months. RESULTS: The desmoplastic subtype required significant more re-excisions (70.0% vs 23.9%, p < .001), more interventions until tumor-free margins were achieved (maximal 6 vs 2; p < .001), showed more widespread tumor infiltration with larger excisional margins (median 9 mm, 2-51 mm vs median 4 mm, 1-10 mm; p < .001), and a 5-fold higher local recurrence rate (26.7% vs 5.0%, p < .001). The metastasis rate (16.6% vs 2.3%, p < .001) was increased. CONCLUSION: The desmoplastic subtype is characterized by a widespread local infiltration associated with perineural infiltration. It seems to be a marker for decreased histological detectability with a high rate of locoregional recurrence and metastasis.

Removal of the deep fascia is recommended in therapy for dermatofibrosarcoma protuberans, but its necessity in the context of micrographic surgery is unclear. A retrospective clinicopathological analysis of 48 patients with dermatofibrosarcoma protuberans treated by micrographic surgery was performed, to determine in which tumours fascia preservation was feasible and safe. Histologically, 93% of tumours on the trunk and extremities and 14% of tumours in the head and neck region were fully located above the fascia. Localization on the head and neck was the only significant risk factor for tumour extension beyond the subcutis (p<0.001). Overall, 44% of tumours were completely excised above the fascia and 56% with deeper excisions. Two deeply infiltrating tumours (4%) on the head recurred, but in none of these lesions was the fascia spared. These results show that micrographic surgery allows fascia preservation in superficial tumours outside the head and neck region.

Epinephrine supplements in local anesthetics are regularly used for surgery in areas with terminal vessels. According to the pharmaceutical guidelines, the use of epinephrine as an additive to local anesthetics is contraindicated for these areas. This review provides an overview of the current scientific data as well as new clinical developments in various fields. It also reviews the current legal situation. A literature research was carried out to survey the current status of relevant data. Written inquiries to several German institutions (Institute for Quality and Efficiency in Health Care, National Association of Statutory Health Insurance Physicians, Center for Clinical Studies Tübingen, Federal Institute for Drugs and Medical Devices) were made to determine the legal situation. No evidence was found in the literature for a causal relationship between the use of epinephrine as a vasoconstrictor and necrosis of the finger or penis. Studies and reviews show that the use of local anesthetics with epinephrine on the fingers or penis is a safe procedure with many clinical and economic advantages. In routine clinical practice, the WALANT method (Wide Awake Local Anesthesia No Tourniquet) as well as the increasing incidence of skin tumors in acral areas has led to a tendency towards increasing use. However, its use is still legally contraindicated, and the pharmaceutical companies show no interest in supporting a drug study. Further clinical trials - regardless of the strength of the evidence - would not change the current legal contraindication.

HINTERGRUND: Primär kutane Lymphome (PCL) unterscheiden sich oft stark im klinischen Verhalten und in der Prognose von systemischen Lymphomen des gleichen histopathologischen Typs. Ziel der Studie war es, die Verteilung der PCL-Subtypen, die Zeitspanne von der Krankheitsmanifestation bis zur Diagnosestellung, den Stellenwert diagnostischer Verfahren, das Auftreten von Zweittumoren und die verschiedenen Behandlungsmodalitäten im Rahmen des Krankheitsverlaufs zu untersuchen. PATIENTEN UND METHODIK: Retrospektive Analyse von 152 Patienten mit PCL, die von 2010-2012 an der Universitäts-Hautklinik Tübingen behandelt wurden. ERGEBNISSE: 105 Patienten mit primär kutanem T-Zell-Lymphom (CTCL) (69,1 %) und 47 Patienten mit primär kutanem B-Zell-Lymphom (CBCL) (30,9 %) wurden eingeschlossen. Die Zeitspanne von der Krankheitsmanifestation bis zur Diagnose betrug durchschnittlich vier Jahre. Mycosis fungoides (MF) (47,4 %) wurde am häufigsten diagnostiziert. Die First-Line-Therapien umfassten hier entweder eine alleinige Phototherapie (PUVA, n = 48; UVB 311 nm, n = 7) oder Kombinationstherapien (PUVA mit systemischen Retinoiden, n = 18). Häufigste Second-Line-Therapie war Interferon (INF)-α plus PUVA (n = 15). Der Behandlungsverlauf war insgesamt günstig (45,2 % Remission, 28,6 % stabile Erkrankung, 22,6 % Progress). Maligne Komorbiditäten wurden im Vergleich zu einer gesunden Vergleichsgruppe häufiger beobachtet. SCHLUSSFOLGERUNGEN: Bis zur Diagnosestellung der PCL dauert es oft mehrere Jahre. Der Wert der Staging-Verfahren ist gering. Die Behandlungsmodalitäten in früheren MF-Stadien basieren hauptsächlich auf der Phototherapie.
RESUMO
BACKGROUND AND OBJECTIVES: Primary cutaneous lymphomas (PCL) often strongly differ in clinical behavior and prognosis from systemic lymphomas of the same histopathologic type. The aim of the study was to investigate the distribution of PCL subtypes, the average time from disease manifestation to diagnosis, the importance of diagnostic procedures, the occurrence of secondary malignancies and the different treatment modalities. PATIENTS AND METHODS: Retrospective analysis of 152 patients with PCL examined at the Department of Dermatology of the University Hospital Tübingen from 2010-2012. RESULTS: 105 patients with CTCL (69.1 %) and 47 patients with CBCL (30.9 %) were included. The average time from disease manifestation to diagnosis was four years. The most common diagnosed lymphoma was mycosis fungoides (MF) (47.4 %). First-line therapies here include phototherapy only (psoralen-UV-A [PUVA], n = 48; UVB 311 nm, n = 7) or combination therapies primarily phototherapy with systemic retinoids (n = 18). Most frequent second-line therapy was interferon (INF)-α plus PUVA (n = 15). The outcome was favorable (45.2 % remission, 28.6 % stable disease, 22.6 % progressive disease). Malignant comorbidities were observed more frequently compared to a healthy control group. CONCLUSIONS: The diagnosis of lymphoma often takes several years. The value of staging procedures is still low and the treatment modalities for MF in earlier stages are mainly based on phototherapy.

BACKGROUND: Basal cell carcinomas are the most frequent epithelial skin tumors and a frequent indication for dermatological interventions. Despite the establishment of drug treatment options, surgery is still the treatment of choice. Various options are available ranging from curettage to complex dermatosurgical procedures. In addition to the main aspect of low local recurrence rates, esthetic factors and the number of procedures are also important for the choice of treatment. METHODS: In this study 347 patients with 398 basal cell carcinomas (nodular type, diameter up to 10 mm) were prospectively examined. The patients were randomized into two treatment arms: in one group the tumor was treated by ring curettage and in the other group the tumor was excised. Patients who underwent 3D histologically controlled surgery due to basal cell carcinoma during the same investigation period served as controls. RESULTS: The highest local recurrence rate was observed after curettage (14.0%), whereas the group with 3D histology had the lowest recurrence rate (0.9%, pâ¯< 0.001). In the 3D group, more re-excisions were required to achieve complete tumor clearance compared to the group who underwent excisions with serial section histology. Patients rated the esthetic outcome best after curettage. The median follow-up was 3.9 years. CONCLUSION: The choice of surgical treatment for small nodular basal cell carcinomas depends on individual circumstances. Excisions controlled by 3D histology with wound closure after complete tumor clearance showed the lowest recurrence rate in our study; however, curettage is also a possible surgical treatment option with minimal effort and an acceptable recurrence rate, which can lead to good esthetic results.

HINTERGRUND: Nach Tumoroperationen erfolgt ein Defektverschluss mit den für den individuellen Fall optimalen chirurgischen Methoden. Besonders im Kopf-Hals--Bereich ist das Ergebnis sehr wichtig. Ziel der retrospektiven Studie war es, Rekonstruktionsmethoden von Defekten entsprechend Alter, Lokalisation und Größe nach funktionellen und ästhetischen Gesichtspunkten zu vergleichen. PATIENTEN UND METHODIK: Die betroffenen Patienten wurden mittels Fragebögen angeschrieben. 1827 Patienten (Alter von 18 bis 92 Jahren, Median: 56 Jahre) beurteilten postoperative Probleme, ästhetisches sowie funktionelles Ergebnis und das Gesamtresultat. Aus der Patientenakte wurden Größe und Lokalisation des Defektes sowie die Art des Verschlusses dokumentiert. ERGEBNISSE: Die Dehnungslappenplastik erhielt bezüglich des Gesamtresultats mit einer sehr guten oder guten Bewertung (86 %) das beste Ergebnis. Lappenplastiken und Hauttransplantate wurden schlechter beurteilt. Postoperative Beschwerden traten signifikant häufiger nach lokalen Lappenplastiken auf. Die Sichtbarkeit der Narbe wurde von älteren Patienten bei allen Defektgrößen (< 150 mm2 , 150-300 mm2 , > 300 mm2 ) geringer beurteilt als von jüngeren. Narben in der zentralen Gesichtspartie wurden als sichtbarer wahrgenommen. Geschlecht und Rauchen hatten keinen Einfluss. SCHLUSSFOLGERUNGEN: Narben in zentralen Gesichtsregionen werden stärker wahrgenommen. Ältere Patienten beurteilten die Narbenbildung insgesamt als unauffälliger. Dehnungslappenplastiken, auch unter Wundrandspannung, führen zu sehr guten Ergebnissen und einer hohen Patientenzufriedenheit.
RESUMO
BACKGROUND: Defect coverage following tumor excision requires a case-by-case decision as regards the optimal reconstruction technique. In the head and neck region in particular, the cosmetic outcome is of major importance. The objective of the present study was to compare various reconstruction methods in terms of their functional and aesthetic outcome based on patient age, defect size and site. PATIENTS AND METHODS: Overall, 1,827 patients (age: 18-92 years, median age: 56 years) were contacted. Using a standardized questionnaire, they were asked to assess postoperative complications, cosmetic and functional outcome, and the overall result of the surgical procedure. In addition, patient records were used to collect data on defect size and site as well as the type of surgical procedure employed. RESULTS: Rated as very good or good (86 %), defect closure by advancement flaps received the highest scores in terms of overall result. Other flaps and skin grafts were rated less favorably. Postoperative complications were significantly more common after local flaps. Irrespective of defect size (< 150 mm2 , 150-300 mm2 , > 300 mm2 ), older patients considered the visibility of the scar to be less prominent than younger individuals. Scars in the central facial region were perceived to be more visible. Gender and smoking habits had no impact on the results of the survey. CONCLUSIONS: Scars in the central facial region were perceived to be more prominent. Overall, older individuals considered their scars to be less conspicuous. Even though they are initially associated with greater tension, advancement flaps resulted in very good aesthetic and functional results and a high level of patient satisfaction.

BACKGROUND: Cutaneous sarcomas are rare and characterized by pathogenetic heterogeneity. Knowledge about local infiltration patterns and recurrence rates may be useful in improving patient care and outcomes. The objective of the present study was to compare these two characteristics in sarcomas that had been treated using the identical surgical procedure. PATIENTS AND METHODS: Between 2006-2010, 84 patients with various types of sarcoma underwent surgery followed by three-dimensional histology. Tumor entities included dermatofibrosarcoma protuberans (DFSP, 54 patients), leiomyosarcoma (ten patients), rhabdomyosarcoma (one patient), angiosarcoma (seven patients) as well as atypical fibroxanthoma (AFX, three patients) and cutaneous undifferentiated pleomorphic sarcoma (UPS, nine patients). Median follow-up was four years (range: 2-6 years). RESULTS: Local recurrence rates among patients with primary DFSP were 2.2 %. All patients undergoing re-excision were subsequently tumor free. Patients with leiomyosarcoma, rhabdomyosarcoma, AFX, and cutaneous UPS experienced no local recurrence; however, one individual developed in-transit metastasis (UPS) (8.3 %). Three patients with angiosarcoma developed local recurrence (43 %), two of whom remained tumor free following re-excision. Two angiosarcoma patients died from distant metastases (29 %). Both DFSP and especially angiosarcoma lesions exhibited extensive subclinical growth. CONCLUSIONS: Recurrence rates of cutaneous sarcomas following three-dimensional histology are low. Local recurrences are readily manageable by re-excision. Angiosarcoma is characterized by extensive superficial growth, aggressive biological behavior, and predominantly hematogenous spread.

Basal-cell carcinomas may show irregular, asymmetric subclinical growth. This study analyzed the efficacy of 'breadloaf' microscopy (serial sectioning) and three-dimensional (3D) microscopy in detecting positive tumor margins. Two hundred eighty-three (283) tumors (51.2%) were put into the breadloaf microscopy group; 270 tumors (48.8%) into the 3D microscopy group. The position of any detected tumor outgrowths was identified in clock face fashion. The time required for cutting and embedding the specimens and the examination of the microscopic slides was measured. Patient/tumor characteristics and surgical margins did not differ significantly. Tumor outgrowths at the excision margin were found in 62 of 283 cases (21.9%) in the breadloaf microscopy group and in 115 of 270 cases (42.6%) in the 3D microscopy group, constituting a highly significant difference (p < 0.001). This difference held true with incomplete excision of fibrosing (infiltrative/sclerosing/morpheaform) tumors [32.9% in the breadloaf microscopy group and 57.5% in the 3D microscopy group (p = 0.003)] and also with solid (nodular) tumors [16.1 and 34.2%, respectively (p < 0.001)]. The mean overall examination time required showed no important difference. In summary, for detection of tumor outgrowths, 3D microscopy has almost twice the sensitivity of breadloaf microscopy, particularly in the situation of aggressive/infiltrative carcinomas.

INTRODUCTION: Trapeziometacarpal joint osteoarthritis is a very common degenerative joint disease which affects especially women between their fifth and sixth decade of life. To determine the final pinch, grip and functional outcome after trapeziometacarpal arthroplasty and to compare to non-arthritic controls, we hypothesized that patients after the former surgery are expected to have lower grip and pinch strength and a higher DASH score. MATERIALS AND METHODS: 44 women (range 50-65 years of age; median 57 years of age) were examined after resection-interposition arthroplasty because of trapeziometacarpal joint osteoarthritis Eaton-Littler stage 3 and 4 with a minimum follow-up time of 12 months (range 12-99 months; median 47 months) using DASH questionnaire and grip and pinch strength evaluation. The control group consisted of 107 healthy age-matched controls (range 50-64 years of age; median 54 years of age). Differences between both groups were statistically analysed using analysis of covariance. RESULTS: A significant loss of pinch strength and a significant higher DASH score were detected for the patient group in comparison to the controls, whereas grip strength did not differ significantly. CONCLUSIONS: A loss of pinch strength in conjunction with a higher DASH score was detected. The expected loss of pinch strength in conjunction with a reduced physical functionality should be discussed preoperatively with the patient to meet the expectations and to offer the best suitable treatment option.

BACKGROUND: It is widely accepted that local anesthetics with epinephrine should not be used in areas served by terminal vessels. There is no evidence in studies for this in penile surgery, and given the anatomy of the penis, perfusion complications are highly unlikely. The goal of this study was to show that a penile block using a local anesthetic with epinephrine is safe. PATIENTS AND METHODS: In a follow-up study between 2005 and 2010, we analyzed 95 patients who got a penile ring block with subcutaneous infusion anesthesia (SIA). The SIA solution consisted of ropivacaine and lidocaine (0.11% and 0.21%) plus epinephrine. RESULTS: There were no anesthetic complications. Short-term negative postoperative occurrences (<72 hrs.) were swelling (42%), problems with suture material (22%), pain (19%), hematoma and paresthesia (each 13%), erectile dysfunction (12%), small-area skin necrosis after wound healing without requiring further surgery (13%), micturition disorders (7%), and wound infection (6%). Two patients on anticoagulation therapy had postoperative bleeding requiring revision surgery. 5% of the patients were given further analgesic sedation. 19% complained about postoperative pain. Persistent complaints (maximum 6 months) were disturbances of skin sensation (7%), swelling (4%), and redness and micturition disorders (3% each). CONCLUSIONS: Supplementing a local anesthetic with epinephrine in penis operations has many advantages, including high patient satisfaction, relatively painless infiltration, low complication rates, improved view of the operating field, and an extended effect of anesthetics with a prolonged reduction in pain. Because of the anatomy of the organ, there is no risk of necrosis related to using a subcutaneous penile ring block. Thus the view that epinephrine should not be used in penis procedures is obsolete.

BACKGROUND: The continuous evaluation of the edges of a tumor by means of three-dimensional (3D) histology often appears complicated and require the surgeon and dermatopathologist to work together closely. We present clear rules that allow communication between all parties involved and then verify their application in daily routine. METHODS: Tissue processing, interpretation of results, as well as communication between the surgeon and the dermatopathologist are based on an algorithm with the aid of exact times and embedding cassettes, which allow precise topographic orientation. We evaluated the use of this method in daily clinic practice, taking into account 947 operated basal cell carcinomas in regard to the development of recurrent tumors. RESULTS: At a median follow-up of 47 months, 10 of the 947 operated basal cell carcinomas (1.1 %) recurred. Sclerodermiform basal cell carcinomas and basal cell carcinomas which could not be curatively resected (R0 resection) during the initial surgery showed a significantly higher recurrence rate (p < 0.05 and p < 0.001). CONCLUSIONS: Standardized rules for dealing with excised tissue allow an effective application of 3D histology in daily clinical practice. 3D histology results in low recurrence rates. Sclerodermiform basal cell carcinomas which could not be curatively resected (R0 resection) were identified as a risk group for the development of recurrent tumors.

The aim of the study was to evaluate the clinical outcome with subjective and neurophysiological parameters following partial medial epicondylectomy (pME) and to evaluate complications and recurrence rates. A retrospective analysis was performed in 29 patients (18 males and 11 females) with cubital tunnel syndrome (CuTS) who underwent pME. Mean time follow-up was 41.4 months. For subjective parameters, DASH (Disabilities of Arm, Shoulder and Hand), a self-created questionnaire about postoperative satisfaction and a visual pain scale (VAS) have been used. All patients were classified according to the Mc Gowan Classification (McG) and Wilson & Krout Classification (WKC). The patients were examined by nerve conduction velocity. Total mean of the DASH score was 24.8 points. In a questionnaire with integrated pain score (1-5), 96% of the patients declared a postoperative improvement, whereas 41.4% patients of the latter group were very contented with the results, 37.9% were contented, 17.2% were less contented and 3.4% were discontented. The VAS for evaluation of postoperative pain showed an average of 2.36 (0-5.9) out of 10. Of the patients, 68.0% were classified as grade I according to McG and 68.0% as excellent or good according to WKC. Motor nerve conduction velocity improved from 34.8 m/s preoperatively to 48.2 m/s postoperatively. One patient developed a haematoma and three patients (10.3%) had to be classified as recurrence. High postoperative rates of patient satisfaction and improved neurophysiological results could be achieved by pME.

BACKGROUND: Although multiple strategies for autologous breast reconstruction exist, a vertical midline scar in the abdominal wall as a result of previous laparatomy or abdominoplasty represents a major surgical challenge. To date, little research has been conducted on the regeneration potential of the abdominal wall's superficial vascular, perforator and choke vessel system after surgery using a vertical approache. METHODS: We present the cases of 8 patients, of whom 7 underwent autologous breast reconstruction. One patient received a thigh reconstruction. All patients had a vertical abdominal midline scar as a result of a previous surgical intervention. In 3 of the 7 patients, the breast was reconstructed using an MS-2-vertical rectus abdominis myocutaneous (VRAM) free flap. In 4 of these patients, an MS-2-transverse rectus abdominis myocutaneous (TRAM) free flap was performed. The thigh reconstruction used a transverse deep inferior epigastric perforator (DIEP) free flap. Clinical followup was done 12 months after operation. RESULTS: All 3 patients who received an MS-2-VRAM had good aesthetic results. Vertical midline scars had no negative effect on surgical outcomes, perfusion and tissue viability of the 4 MS-2-TRAM and transverse DIEP free flaps. CONCLUSION: These clinical findings indicate that the regeneration potential of the abdominal wall's superficial vascular system in the presence of vertical surgical scars has been greatly underestimated. Use of MS-2-VRAM free flaps in patients with vertical abdominal scars seems to be a suitable and successful alternative in the reconstruction algorithm.
