An Updated Comprehensive Review of Existing Transcatheter Aortic Valve Replacement Access.

For the past 20years, transcatheter aortic valve replacement (TAVR) has been the treatment of choice for symptomatic aortic stenosis. The transfemoral (TF) access is considered the gold standard approach for TAVR. However, TF-TAVR cannot be performed in some patients; thus, alternative accesses are required. Our review paper generalises the TAVR accesses currently available, including the transapical, transaortic, trans-subclavian/axillary, transcarotid, transcaval, and suprasternal approaches. Their advantages and disadvantages have been analysed. Since there is no standard recommendation for an alternative approach, access selection depends on the expertise of the local cardiac team, patient characteristics, and access properties. Each TAVR centre is recommended to master a minimum of one non-TF access alternative. Of note, more evidence is required to delve into the clinical outcomes of each approach, at both early and long-term (Figure 1).

Patients, healthcare providers, and general population preferences for hemodialysis vascular access: a discrete choice experiment.

A patient-centered dialysis treatment option requires an understanding of patient preferences for alternative vascular accesses and nephrologists often face difficulties when recommending vascular access to end-stage kidney disease (ESKD) patients. We aimed to quantify the relative importance of various vascular access characteristics to patients, healthcare providers and general population, and how they affect acceptability for patients and healthcare providers. In a discrete choice experiment, patients with maintenance hemodialysis (MHD), healthcare providers, and individuals from the general population were invited to respond to a series of hypothetical vascular access scenarios that differed in five attributes: cumulative patency, infection rate, thrombosis rate, cost, and time to maturation. We estimated the respondents' preference heterogeneity and relative importance of the attributes with a mixed logit model (MXL) and predicted the willingness to pay (WTP) of respondents via a multinomial logit model (MNL). Healthcare providers (n = 316) and the general population (n = 268) exhibited a favorable inclination toward longer cumulative patency, lower access infection rate and lower access thrombosis rate. In contrast, the patients (n = 253) showed a preference for a 3-year cumulative patency, 8% access infection rate, 35% access thrombosis rate and 1.5 access maturity time, with only the 3-year cumulative patency reaching statistical significance. Among the three respondent groups, the general population found cumulative patency less important than healthcare providers and patients did. Patients demonstrated the highest WTP for cumulative patency, indicating a willingness to pay an extra RMB$24,720(US$3,708) for each additional year of patency time. Patients and healthcare providers had a strong preference for vascular access with superior patency. While the general population preferred vascular access with lower thrombosis rates. These results indicate that most patients prefer autogenous arteriovenous fistula (AVF) as an appropriate choice for vascular access due to its superior patency and lower complications than other vascular access types.

Current alternatives to traditional radial approach for coronary interventions: A randomized prospective study of the ulnar and distal radial approaches.

The radial artery is the standard access for coronary intervention; however, it is essential to have alternative accesses as it may be used as a conduit during coronary artery bypass grafting or for dialysis fistula. Ulnar and distal radial artery accesses have emerged as alternative accesses for traditional radial artery. To compare distal radial artery access and ulnar artery access as alternatives to traditional radial artery access regarding safety, efficacy, and success rate. Two-hundred patients were included (100 traditional radial [TRA], 50 distal radial [DRA] and 50 ulnar). Access artery follow up ultrasound was performed up to 28 days. Procedural success rate was 97%, 74%, and 92% in the TRA, DRA and ulnar groups, respectively (p < 0.001). Crossover occurred in 3 patients (3%) in TRA, 13 patients (26%) in DRA and 4 cases (8%) in ulnar group (p < 0.001). The most common cause of crossover was failure of artery cannulation. Regarding cannulation time, the mean access time in seconds was 80.19 ± 25.98, 148.4 ± 29.60, 90.5 ± 21.84 in TRA, DRA and ulnar groups, respectively (p < 0.001). Our study concluded that these new approaches proved to be potential alternatives to traditional radial approach; however, ulnar artery access proved to be superior to distal radial artery access as regards success rate and cannulation time.

Extrathoracic Against Intrathoracic Vascular Accesses for Transcatheter Aortic Valve Replacement: A Systematic Review With Meta-Analysis

Alternative vascular accesses to transfemoral access for transcatheter aortic valve replacement (TAVR) can be divided into intrathoracic (IT)-transapical and transaortic- and extrathoracic (ET)-transcarotid, transsubclavian, and transaxillary. This study aimed to compare the outcomes and safety of IT and ET accesses for TAVR as alternatives to transfemoral access. A systematic review with meta-analysis was performed by searching PubMed/MEDLINE and EMBASE databases for all studies comparing IT-TAVR with ET-TAVR published until April 2023. Outcomes included in-hospital or 30-day all-cause mortality (ACM), 1-year ACM, postoperative and 30-day complications. A total of 18 studies with 6,800 IT-TAVR patients and 5,032 ET-TAVR patients were included. IT accesses were associated with a significantly higher risk of in-hospital or 30-day ACM (relative risk 1.99, 95% confidence interval 1.67 to 2.36, p <0.001), and 1-year ACM (relative risk 1.31, 95% confidence interval 1.21 to 1.42, p <0.001). IT-TAVR patients presented more often with postoperative life-threatening bleeding, 30-day new-onset atrial fibrillation or flutter, and 30-day acute kidney injury needing renal replacement therapy. The risks of postoperative permanent pacemaker implantation and significant paravalvular leak were lower with IT-TAVR. ET-TAVR patients were more likely to be directly discharged home. There was no statistically significant difference regarding the 30-day risk of stroke. Compared with ET-TAVR, IT-TAVR was associated with higher risks of in-hospital or 30-day ACM, 1-year ACM and higher risks for some critical postprocedural and 30-day complications. Our results suggest that ET-TAVR could be considered as the first-choice alternative approach when transfemoral access is contraindicated.

Transcatheter Aortic Valve Implantation Using the Transcervical Vascular Access (from a 7-Year Experience from a Swiss Tertiary Center)

The gold-standard transfemoral (TF) access for transcatheter aortic valve implantation (TAVI) is not suitable in 10% to 15% of patients, and alternative accesses are needed. Studies have suggested that the transcervical (TC) access might yield outcomes comparable to the TF access. In our center, TC-TAVI is the first-line alternative to TF-TAVI. We herein present our 7-year experience regarding the use of the TC access in TAVI. We included all consecutive patients referred for TC-TAVI between January 1, 2016 and December 31, 2022. Data regarding the patients' characteristics,perioperative and 30-day outcomes were prospectively collected. Patients were separated into 2 temporal groups (group 1: January 1, 2016 to June 30, 2019; group 2: July 1, 2019 to December 31, 2022) to assess the changes of their characteristics and outcomes over time. A total of 95 patients were included, with more belonging to group 2 (n=56 vs n=39 in group 1). Patients in group 2 were significantly younger (81.0 [interquartile range 77.0 to 87.0] vs 89.0 [interquartile range 83.0 to 92.0] years, p <0.001) and had a higher prevalence of hypertension (87.5% vs 66.7%, p=0.028) and chronic pulmonary disease (35.7% vs 15.4%, p=0.029). There was no significant difference regarding other co-morbidities or surgical scores. All-cause mortality and the risk of stroke at 30days were low and similar (group 2 vs group 1, 3.6% vs 2.5%, p=0.787 and 1.8% vs 0%, p=0.397, respectively), as were the risks of permanent pacemaker implantation, postoperative acute kidney injury, cardiac tamponade, life-threatening bleeding, and major vascular complications. In conclusion, the use of the TC access increased over time. The rates of adverse events did not change, despite patients from mid-2019 onward having slightly more co-morbidities.

Alternative (Transulnar or Distal Radial) Arterial Access for Chronic Total Occlusion Percutaneous Coronary Intervention (Subanalysis from the Minimalistic Hybrid Approach Algorithm Registry)

The transradial approach (TRA) has become the primary choice for percutaneous coronary intervention (PCI); however, it may not be always feasible because of clinical and/or technical challenges. Alternative forearm accesses, such as transulnar approach (TUA) and distal radial approach (dTRA) may allow maintaining a wrist approach for the procedure, avoiding the femoral artery. This issue is particularly relevant in patients who underwent multiple revascularizations, such as those with chronic total occlusion (CTO) lesions. This study aimed to evaluate whether the use of TUA and/or dTRA is comparable with TRA in CTO PCI using a minimalistic hybrid approach algorithm, which limits the number of accesses used to minimize vascular access complications. Patients with CTO PCI treated solely through a fully alternative approach (TUA and/or dTRA) were compared with those treated solely through a standard TRA approach. The primary efficacy end point was procedural success, whereas the primary safety end point was the composite of major adverse cardiac and cerebral events and vascular complications. Of 201 CTO PCIs attempted, 154 procedures were considered for analysis (standard, n = 104, alternative, n = 50). Alternative and standard groups demonstrated comparable rates of both procedural success (92% vs 94.2%, p = 0.70) and primary safety end point (4.8% vs 6.0%, p = 0.70). Of interest, 7 French guiding catheters were more frequently used in the alternative group (44% vs 26%, p = 0.028). In conclusion, CTO PCI after minimalistic hybrid approach by way of alternative forearm vascular accesses (dTRA and/or TUA) is feasible and safe to perform, compared with CTO PCI by way of standard TRA.

P298 TRANS–AXILLARY ACCESS AS AN ALTERNATIVE ROUTE IN TRANSCATHETER AORTIC VALVE IMPLANTATION

Abstract Background Transcatheter aortic valve replacement (TAVR) is the main procedure for treating severe aortic stenosis in patients considered at high surgical risk. Generally, this procedure is performed through percutaneous femoral arterial access. The presence of anatomical variants or peripheral atherosclerotic pathology sometimes necessitates the use of alternative vascular accesses, including access through the axillary artery. Data from a meta–analysis involving 1793 patients who underwent TAVR through trans axillary or transapical access showed a statistically significant reduction in 30–day mortality in the former group. We wait for future randomized trials to confirm the consistency of these data. Clinical case 71–year–old man, smoker, hypertensive and dyslipidaemic. In 2018, he underwent bilateral aorta–iliac–femoral bypass surgery for severe lower limb arteriopathy. Due to the onset of angina and dyspnea at rest, he went to the ER where a diagnosis of NSTEMI was made. On echocardiogram, there was evidence of severe high–gradient aortic stenosis while coronary angiography showed 80% RCA stenosis in the middle tract. Because of the high surgical risk (EUROSCORE II: 12%) and the evidence of bilateral femoral artery occlusion on CT–angiography, the Heart Team concluded to perform TAVR through percutaneous left trans–axillary access with concomitant percutaneous coronary revascularization. Obtained the backup access on the left radial artery, PTCA+DES was performed on RCA through the right radial access with subsequent placement of a pigtail catheter in the non–coronary sinus of Valsalva. Once the temporary pacemaker had been placed through the right femoral vein, an angio–guided puncture of the left axillary artery was performed with placement of the 14 Fr introducer for implantation of the Medtronic Evolut R 26 mm aortic biological prosthesis. Post–procedure ultrasound examination showed a residual mean aortic valve gradient of 17 mmHg with evidence of a small periprosthetic leak. Seven days after the procedure, the patient was discharged, asymptomatic and in good hemodynamic compensation without vascular complications. Conclusions Trans–axillary arterial access should be considered a viable alternative to transfemoral access for the performance of TAVR.

Comparison of transcarotid versus transapical transcatheter aortic valve implantation outcomes in patients with severe aortic stenosis and contraindications for transfemoral access.

The purpose of this study was to compare the safety and clinical outcomes of transcarotid (TC) and transapical access (TA) transcatheter aortic valve implantation (TAVI) patients whom the transfemoral approach (TF) was not feasible. The analysis included consecutive patients with severe symptomatic aortic stenosis treated from 2017 to 2020 with TC-TAVI or TA-TAVI in two high-volume TAVI centers. The approach was selected by multidisciplinary heart teams after analyzing multislice computed tomography of the heart, aorta and peripheral arteries, transthoracic echocardiography and coronary angiography. One hundred and two patients were treated with alternative TAVI accesses (TC; n = 49 and TA; n = 53) in our centers. The groups were similar regarding age, gender, New York Heart Association class, and echocardiography parameters. Patients treated with TC-TAVI had significantly higher surgical risk. The procedural success rate was similar in both groups (TC-TAVI 98%; TA-TAVI 98.1%; p = 0.95). The rate of Valve Academic Research Consortium-2 defined clinical events was low in both groups. The percentage of new-onset rhythm disturbances and permanent pacemaker implantation was similar in TC and TA TAVI (4.1% vs. 11.3%; p = 0.17 and 10.2% vs. 5.7%; p = 0.39, respectively). In the TA-TAVI group, significantly more cases of pneumonia and blood transfusions were observed (11% vs. 0%; p = 0.01 and 30.2% vs. 12.2%; p = 0.03). The 30-day mortality was similar in TC and TA groups (4.1% vs. 5.7%; p = 0.71, respectively). Both TC and TA TAVI are safe procedures in appropriately selected patients and are associated with a low risk of complications.

Meta-Analysis on Transcarotid Versus Transfemoral and Other Alternate Accesses for Transcatheter Aortic Valve Implantation

Transcarotid access has emerged as the preferred access site for transcatheter aortic valve implantation (TAVI) in patients with prohibitive iliofemoral anatomy. This study aimed to compare outcomes with transcarotid with those of other accesses in patients who underwent TAVI. Cochrane, EMBASE, and MEDLINE databases were searched for all published studies that compared outcomes with transcarotid with those of other accesses (transfemoral, transaxillary/subclavian, transaortic, and transapical) in patients who underwent TAVI. The primary outcome was all-cause mortality. Secondary outcomes included major bleeding, major vascular complications, stroke, myocardial infarction, permanent pacemaker implantation, and peri-aortic valve insufficiency. We included 22 observational studies with a total of 11,896 patients. Outcomes were reported during hospitalization and at 1-month follow-up. The transcarotid approach had higher mortality at 1month (3.7% vs 2.6%, p=0.02) but lower major vascular complications during hospitalization (1.5% vs 3.4%, p=0.04) than did transfemoral access. The transcarotid approach had lower major vascular complications (2% vs 2.3%, p=0.04) than did the transaxillary/subclavian but higher major bleeding (5.3% vs 2.6%, p=0.03). The transaortic approach was associated with higher in-hospital (11.7% vs 1.9%, p=0.02) and 1-month mortality (14.4% vs 3.9%, p=0.007) rates than was transcarotid access. The transcarotid approach numerically reduced mortality and the risk of major vascular complications and major bleeding compared with the transapical approach; however, this did not reach statistical significance. The transcarotid approach did not increase the risk of stroke compared with transfemoral or the other alternative accesses. In conclusion, the transcarotid or transaxillary/subclavian approach had associated comparable outcomes that were better than those of the transapical and transaortic approaches. There was no difference in stroke risk between transcarotid access and other accesses.

Isolated retrograde puncture for the endovascular treatment of peripheral vascular disease

The risks of femoral puncture encourage the search for alternative accesses. Angioplasties through the isolated retrograde puncture of an artery of the foot were described (Tibiopedal Arterial Minimally Invasive Retrograde Revascularization - TAMI) but the data remain very limited. We present here a study of feasibility and safety of the TAMI technique conducted in two centers.

Alternative vascular accesses in electrophysiological operating rooms: focus on the quality of life in the early postoperative period

Atrial fibrillation is the most common arrhythmia, the incidence of which increases in parallel with the progressive aging of the population. Atrial fibrillation worsens the prognosis of patients and significantly reduces the quality of life. Improvement of the technical and methodological aspects of catheter procedures leads to their widespread introduction into clinical practice both for the prevention of embolic events and for rhythm control. The need to provide access to the main vessels, more often to the femoral veins, the use of large bore introducers, as well as aggressive regimens of antithrombotic therapy in the postoperative period, bring to the fore local complications of catheter procedures and necessitates to maintain a horizontal position to achieve stable hemostasis. The use of ultrasound imaging can significantly reduce the number of vascular events. However, long-term immobilization often leads to back pain, urinary retention, and infectious complications, which is more pronounced in the older patient population. In order to reduce the immobilization time, many hemostasis systems have been developed, which have disadvantages and require additional costs for the treatment of patients. In this regard, the development and introduction into clinical practice of novel vascular access types to improve the quality of life in the early postoperative period seems relevant. For this purpose, a randomized study is conducted, which compares the efficacy and safety of the distal femoral access, which makes it possible to activate patients as soon as possible after surgery.

Systematic Review on Endovascular Access to Intracranial Arteries for Mechanical Thrombectomy in Acute Ischemic Stroke.

In acute ischemic stroke for large vessel occlusions, delayed or failed access to intracranial occlusions has anegative impact on procedural and clinical outcomes. The aim of this review is to identify and quantify access failures and challenges in mechanical thrombectomy. Asystematic literature review of PubMed and Scopus databases from January 2014 to October 2020 was performed. Articles reporting consecutive patients were used to calculate acrude failure rate of femoral and alternative accesses. A total of 50articles met the inclusion criteria, totalling 12,838 interventions. Failure to access the occlusion through transfemoral access occurred in 4.4% of patients, most commonly due to challenging supra-aortic vessel anatomy, decreasing to 3.6% when all alternative access routes were attempted. Failed access from alternative routes (direct carotid, radial and brachial approaches) attempted first-line or after failed femoral attempt were reported in 7.3% of patients. The occurrence rate of potentially challenging features (anatomical, diseases or others) ranged from 4.7% to 47.4%, primarily impacting the access time, procedure time, recanalization and clinical outcomes. Failure to access the occlusion is asignificant contributor to failed recanalization, regardless of access routes. Challenging, but eventually successful access is also arelevant factor in procedural and clinical outcomes; however challenging access requires auniversal definition to enable quantification, so that methods for procedural optimization can be critically assessed.

Left Ventricular Apex: A "Minimally Invasive Motorway" for Safe Cardiovascular Procedures.

Since the advent of TAVR (transcatheter aortic valve replacement), the transapical surgical approach has been affirmed as a safe and effective alternative access for patients with unsuitable peripheral arteries. With the improvement of devices for transfemoral approach and the development of other alternative accesses, the number of transapical procedures has decreased significantly worldwide. The left ventricular apex, however, has proved to be a safe and valid alternative access for various other structural heart procedures such as mitral valve repair, mitral valve-in-valve or valve-in-ring replacement, transcatheter mitral valve replacement (TMVR), transcatheter mitral paravalvular leak repair, and thoracic aorta endovascular repair (TEVAR). We review the literature and our experience of various hybrid transcatheter structural heart procedures using the transapical surgical approach and discuss pros and cons.

The transcervical access for transcatheter aortic valve replacement.

Alternative accesses for transcatheter aortic valve replacement (TAVR) are needed in a certain number of patients, who present contraindications to the standard transfemoral access. We present the transcervical approach, which allows to access the aortic valve via supra-aortic vessels, namely, the brachiocephalic trunk, carotid artery, or subclavian artery. This approach is interesting because it avoids thoracotomy, which is necessary with some other alternative approaches for TAVR, such as the transaortic or transapical ones. Although some points still need clarification, such as the best anesthesia modality (general or local) or the optimal side for vessel access, data suggest the transcervical access might yield similar periprocedural and 30-day outcomes compared with the transfemoral access. Herein, we describe the surgical technique that was developed in our institution for transcervical access.

Percutaneous Endovascular Aneurysm Repair: Current Status and Future Trends.

Endovascular aneurysm repair (EVAR) is a common, safe, and effective method of treating abdominal aortic aneurysms. Traditionally treated via surgical cutdown over the common femoral arteries, many recent studies demonstrate percutaneous access techniques to avoid the surgical cutdown. Developing familiarity with these percutaneous techniques, including risks, complications, adjuncts, and alternative accesses, can help improve the outcomes and availability of EVAR. As these techniques become increasingly common, it is not unlikely that they can be practiced safely in select patients in an outpatient setting.

Femoral Versus Nonfemoral Subclavian/Carotid Arterial Access Route for Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis.

BackgroundSome concerns remain regarding the safety of transcarotid and transsubclavian approaches for transcatheter aortic valve replacement. We aimed to compare the risk of 30‐day complications and death in transcarotid/transsubclavian versus transfemoral transcatheter aortic valve replacement recipients.Methods and ResultsData from 20 studies, including 79 426 patients (16 studies) and 3992 patients (4 studies) for the evaluation of the unadjusted and adjusted impact of the arterial approach were sourced, respectively. The use of a transcarotid/transsubclavian approach was associated with an increased risk of stroke when using unadjusted data (risk ratio [RR], 2.28; 95% CI, 1.90–2.72) as well as adjusted data (odds ratio [OR], 1.53; 95% CI, 1.05–2.22). The pooled results deriving from unadjusted data showed an increased risk of 30‐day death (RR, 1.46; 95% CI, 1.22–1.74) and bleeding (RR, 1.53; 95% CI, 1.18–1.97) in patients receiving transcatheter aortic valve replacement through a transcarotid/transsubclavian access (compared with the transfemoral group), but the associations between the arterial access and death (OR, 1.22; 95% CI, 0.89–1.69), bleeding (OR, 1.05; 95% CI, 0.68–1.61) were no longer significant when using adjusted data. No significant effect of the arterial access on vascular complication was observed in unadjusted (RR, 0.84; 95% CI, 0.66–1.06) and adjusted (OR, 0.79; 95% CI, 0.53–1.17) analyses.ConclusionsTranscarotid and transsubclavian approaches for transcatheter aortic valve replacement were associated with an increased risk of stroke compared with the transfemoral approach. However, these nonfemoral arterial alternative accesses were not associated with an increased risk of 30‐day death, bleeding, or vascular complication when taking into account the confounding factors.

Femoral Versus Nonfemoral Peripheral Access for Transcatheter Aortic Valve Replacement

BackgroundFemoral access is the gold standard for transcatheter aortic valve replacement (TAVR). Guidelines recommend reconsidering surgery when this access is not feasible. However, alternative peripheral accesses exist, although they have not been accurately compared with femoral access. ObjectivesThis study compared nonfemoral peripheral (n-FP) TAVR with femoral TAVR. MethodsUsing the data from the national prospective French registry (FRANCE TAVI [French Transcatheter Aortic Valve Implantation]), this study compared the characteristics and outcomes of TAVR procedures according to whether they were performed through a femoral or a n-FP access, using a pre-specified propensity score−based matching between groups. Subanalysis during 2 study periods (2013 to 2015 and 2016 to 2017) and among low/intermediate-low and intermediate-high/high volume centers were performed. ResultsAmong 21,611 patients, 19,995 (92.5%) underwent femoral TAVR and 1,616 (7.5%) underwent n-FP TAVR (transcarotid, n = 914 or trans-subclavian, n = 702). Patients in the n-FP access group had more severe disease (mean logistic EuroSCORE 19.95 vs. 16.95; p < 0.001), with a higher rate of peripheral vascular disease, known coronary artery disease, chronic pulmonary disease, and renal failure. After matching, there was no difference in the rate of post-procedural death and complications according to access site, except for a 2-fold lower rate of major vascular complications (odds ratio: 0.45; 95% confidence interval: 0.21 to 0.93; p = 0.032) and unplanned vascular repairs (odds ratio: 0.41; 95% confidence interval: 0.29 to 0.59; p < 0.001) in those who underwent n-FP access. The comparison of outcomes provided similar results during the second study period and in intermediate-high/high volume centers. Conclusionsn-FP TAVR is associated with similar outcomes compared with femoral peripheral TAVR, except for a 2-fold lower rate of major vascular complications and unplanned vascular repairs. n-FP TAVR may be favored over surgery in patients who are deemed ineligible for femoral TAVR and may be a safe alternative when femoral access risk is considered too high.

Radial Artery Access for Percutaneous Cardiovascular Interventions: Contemporary Insights and Novel Approaches.

Since its introduction, the transradial access for percutaneous cardiovascular procedures has been associated with several advantages as compared to transfemoral approach, and has become the default for coronary angiography and intervention. In the last 30 years, a robust amount of evidence on the transradial approach has been mounted, promoting its diffusion worldwide. This article provides a comprehensive review of radial artery access for percutaneous cardiovascular interventions, including the evidence from clinical trials of transradial vs. transfemoral approach, technical considerations, access-site complications and limitations, alternative forearm accesses (e.g., ulnar and distal radial artery), and ultimately the use of the radial approach for structural interventions.

Von der Tiefe im Leben sprechen

Existential issues underlie most conversations in counselling, therapy and pastoral care. To explicitly refer to them is difficult for both sides, especially if religious vocabulary is not available, or unwanted. Insights from empirical research on meaning open up alternative accesses. The SoMe-Card Method is a standardized procedure that allows, in a one-hour dialogue setting, to identify and explore personal sources of meaning.

Transoral Thyroidectomy: Anatomical Aspects of an Esthetic Access

IntroductionClassically, ample dissections expose the indisputable beauty of the human structural topography and offer an unquestionable learning opportunity on the syntropy of anatomical repairs, be they by the Letulle (en masse) technique or by the Virchow (organ by organ) method. Jargon of the type: “great surgeons, great incisions,” in light of technological advances, lack in conceptual revision.The traditional transverse cervicotomy, as an access for thyroidectomy, presents itself as consecrated, yet the disagreeable cosmetic aspect in the form of a scar still persists. Surgeons and Anatomists seek alternative accesses, such as the transoral, which could contemplate the same efficacy, safety and outcomes as the transverse cervicotomy. The objective of this study was to verify the viability of using a cadaver fixed in a modified Larsen solution to perform a transoral thyroidectomy for teaching and training.MethodTwo cadavers were carefully dissected in order to obtain safe anatomical parameters, both by the transoral pathway of the subplastimal space, for the resection of the thyroid. Both cadavers were in horizontal dorsal decubitus with a cushion under the shoulder girdle and with the head in hyperextsion. On the first, relaxing and combined incisions were made, going from the right and left labial commissures in the craniocaudal direction to the mandibular tuberosity, and; on the second, 10‐mm trocar punctures were made on the medial line and two 5‐mm punctures in the projections of the lower canine teeth in the buccal vestibule. Both dissections accomplished the detachment of the superficial fascia of the neck, creating space for the exposure of the pre‐thyroid musculature. In sequence, the linea alba was opened, the laryngeal prominence, trachea, thyroid isthmus, upper and lower vascular pedicles of the thyroid, parathyroid glands and right and left recurrent laryngeal nerves were identified and then the gland was removed. In both cadavers, the thyroid region had been clearly totally approached in a safe manner, preserving adjacent structures (Figure 1).ResultsThe thyroid gland was adequately located, as well as its vasculonervous relations. The neck fascia, trachea and innervation of the platysma, motor and sensory muscles were preserved.Discussion and conclusionThe transoral pathway is possible and topographically adequate for performing a thyroidectomy, but the compulsory hyperextension of the head may be contraindicated for patients with cervical spine disorders. The hyperextension was possible, as the fixation by the modified Larsen solution provides sufficient tissue malleability to perform the maneuver.The use of a cadaver presents a safe and reliable alternative in teaching video‐assisted anatomy and for training the resident surgeon.
