Transcatheter aortic valve implantation (TAVI) is a recognized therapy for patients with symptomatic severe aortic stenosis (AS). TAVI is superior compared to medical therapy as for mortality in extreme-risk patients, is non-inferior or superior to surgery in high- risk patients and non-inferior to surgery in intermediate-risk patients. However, several limitations affect outcomes after TAVI. Adverse events related to this procedure, like vascular complications, need forpacemaker implantation, paravalvular regurgitation, can be factors limiting TAVI treatment in younger patients at lower risk, as well as uncertainties regarding valve durability...

Aortic graft infections are a rare but devastating complication of aortic revascularization. Often infections occur due to contamination at the time of surgery. Iatrogenic misplacement of the limbs of an aortobifemoral graft is exceedingly rare, and principles of evaluation and treatment are not well defined. We report 2 cases of aortobifemoral bypass graft malposition through the colon. CASE REPORT: Case 1 is a 54-year-old male who underwent aortobifemoral bypass grafting for acute limb ischemia...

Infrapatellar fat pad is a densely vascularized and innervated extrasynovial tissue that fills the anterior knee compartment. It plays a role in knee biomechanics as well as constitutes a source of stem cells for regeneration after knee injury. Infrapatellar fat pad-derived stem cells (IPFP-ASCs) possess enhanced and age-independent differentiation capacity as compared to other stem cells, which makes them a very promising candidate in stem cell-based regenerative therapy. The aims of this review are to outline the latest advances and potential trends in using IPFP-ASCs and to emphasize the advantages over other sources of stem cells for applications in orthopedic surgery...

BACKGROUND: Vascularized intranasal flaps are the primary reconstructive option for endoscopic skull base defects. Flap vascularity may be compromised by injury to the pedicle or prior endonasal surgery. There is currently no validated technique for intraoperative evaluation of intranasal flap viability. OBJECTIVE: To evaluate the efficacy of indocyanine green (ICG) near-infrared angiography in predicting the viability of pedicled intranasal flaps during endoscopic skull base surgery through a pilot study...

The anatomical location of adipose tissue might have direct implications for its functionality and risk of cardiovascular disease. Adipose tissue surrounding blood vessels may be thermogenically more active in specific areas of the body, releasing substances that regulate vascular metabolism. In humans, the phenotypic characteristics of adipose tissue surrounding the aorta and the cardiovascular disease risk that it might entail remain largely unknown. Here, we compared thermogenesis-related molecular features of human periaortic adipose tissue samples with those of subcutaneous adipose tissue, obtained by sternotomy from 42 patients undergoing cardiovascular surgery...

BACKGROUND: Muscle flap is a valuable option in soft tissue reconstruction. Denervated skeletal muscle is known to undergo degeneration. However, information regarding histological and genetic changes in muscle free flap without reinnervation over long-term follow-up remains unclear. METHODS: We collected flap muscles obtained during secondary exploration surgery after more than 15 years of previous muscle free flap without reinnervation. Compared with normal muscle and fat, histomorphometric and gene expression analysis of flap muscle were performed...

The most widely accepted treatment for cutaneous angiosarcoma (CAS) is wide local excision and postoperative radiation to decrease the risk of recurrence. Positive surgical margins and large tumors (T2, >5 cm) are known to be associated with poor prognosis. Moreover, T2 tumors are known to be associated with positive surgical margins. According to previous reports, the majority of CAS patients in Japan had T2 tumors, whereas less than half of the patients in the studies from western countries did so. Consequently, the reported 5-year overall survival of Japanese CAS patients without distant metastasis was only 9%, lower than that for stage-IV melanoma...

The advantages of thymectomy as part of the treatment of myasthenia gravis has been demonstrated repeatedly in the literature. Both single-institution and multi-institution trials have shown robotic thymectomy to be safe, feasible and associated with better early clinical outcomes than the trans-sternal approach. Most reports have also documented the superiority of robotic technology in the dissection of the superior mediastinum over conventional thoracoscopy, thanks to instruments with more degrees of movement and freedom...

The aim of this study was to explore intraoperative complications during video-assisted thoracoscopic surgery (VATS) lobectomy. Vascular and bronchial injuries, after a robust learning curve, can be sometimes successfully managed by VATS. During a VATS lobectomy, it is necessary: to be prepared in potentially dangerous situations; to think about strategies to handle intraoperative complications and to share these strategies with your own staff. Herein we present some videos showing cases where vascular injuries led to conversion and others where a minimally-invasive trouble shooting of intraoperative complications was achieved...

Introduction: Solid pseudopapillary Carcinoma (SPC) is a rare pancreatic Tumor with variable, usually low, malignancy potential. Howewer, several SPC are associated with aggressive behavior, local vascular infiltration, organ invasion, distant metastasis, and can be unresectable. Irreversible Electroporation (IRE) is an emerging non-thermal ablation technique for the treatment of locally advanced pancreatic carcinoma. We report the results of four year disease-free follow-up in a case of locally advanced unresectable SPC treated with IRE...

Bleeding of an aberrant right subclavian artery following transthoracic en bloc esophagectomy and intrathoracic gastric reconstruction is a rare but severe complication in esophageal surgery. Preoperative diagnosis can be achieved by computed tomography or magnetic resonance angiography (MRA). Various treatment options are available; thus, the treatment can be challenging and should be adjusted to the severity of the symptoms. Bleeding of an aberrant right subclavian artery can result from perioperative vascular injury or various postoperative complications...
