OBJECTIVES: Free flap surgery is an essential procedure in soft tissue reconstruction. Complications due to vascular compromise often require revision surgery or flap removal. We present hyperspectral imaging (HSI) as a new tool in flap monitoring to improve sensitivity compared to established monitoring tools. METHODS: We performed a prospective observational cohort study including 22 patients. Flap perfusion was assessed by standard clinical parameters, Doppler ultrasound, and HSI on t0 (0 h), t1 (16-28 h postoperatively), and t2 (39-77 h postoperatively)...

OBJECTIVES: Aortic neck dilation is a reported mode of failure and can be associated with aneurysm sac expansion following standard endovascular repair of aortic aneurysms. Fenestrated repairs of the juxtarenal segment increase the seal zone length and are often utilized to treat this disease progression. However, the frequency and risk factors for neck dilation following fenestrated repairs is unknown. METHODS: We evaluated 124 consecutive fenestrated EVARs (FEVARs) performed under an investigational device exemption clinical trial for juxtarenal aneurysms (#NCT01538056)...

BACKGROUND: Radial artery (RA) catheterization is the access of choice over femoral artery access for most interventional vascular procedures given its safety and faster patient recovery. There has been growing interest in distal radial artery (dRA) access as an alternative to the conventional proximal radial artery (pRA) access. Preserving the RA is important which serves as a potential conduit for future coronary artery bypass surgery, dialysis conduit or preserve the artery for future cardiovascular procedures...

Bioabsorbable materials made from polymeric compounds have been used in many fields of regenerative medicine to promote tissue regeneration. These materials replace autologous tissue and, due to their growth potential, make excellent substitutes for cardiovascular applications in the treatment of congenital heart disease. However, there remains a sizable gap between their theoretical advantages and actual clinical application within pediatric cardiovascular surgery. This review will focus on four areas of regenerative medicine in which bioabsorbable materials have the potential to alleviate the burden where current treatment options have been unable to within the field of pediatric cardiovascular surgery...

Obesity is a risk factor for at least 13 different types of cancer, many of which are hormonally driven, and is associated with increased cancer incidence and morbidity. Adult obesity rates are steadily increasing and a subsequent increase in cancer burden is anticipated. Obesity-related dysfunction can contribute to cancer pathogenesis and treatment resistance through various mechanisms, including those mediated by insulin, leptin, adipokine, and aromatase signalling pathways, particularly in women. Furthermore, adiposity-related changes can influence tumour vascularity and inflammation in the tumour microenvironment, which can support tumour development and growth...

BACKGROUND: Bypass surgery using a large saphenous vein graft, or another autologous venous graft, is a well-recognised treatment option for managing peripheral arterial disease of the lower limb, including chronic limb-threatening ischaemia (CLTI) and intermittent claudication, peripheral limb aneurysms, and major limb arterial trauma. Bypass surgery has good results in terms of limb preservation rates and long-term graft patency but is limited by the possibility of vein graft failure due to stenoses of the graft...

Opioid analgesia is still considered the standard of practice for cardiac surgery. In recent years, combinations of several nonnarcotic analgesics and regional analgesia have shown promise in restricting opioid use during and after cardiac surgery. Ketamine infusion, dexmedetomidine infusion, acetaminophen, ketorolac, and gabapentin are useful adjuvants in cardiac anesthesia practice and have opioid-sparing properties. The beneficial effects of nonnarcotic multimodal analgesia on intraoperative stress response, recovery profile, postoperative pain, and persistent opioid use after cardiac surgery are yet to be established, and further randomized clinical trials are required...

OBJECTIVES: Patients in the Valiant EVO US and International Clinical Trials had positive short-term outcomes, but late structural failures including Type IIIB endoleaks have been recently discovered. Type IIIB endoleaks are serious adverse events as the re-pressurization of the aneurysm sac increases the risk for rupture. The purpose of this report is to detail the imaging patterns associated with the structural failures with the aim of increasing awareness on failing graft presentation, early recognition, and prompt treatment...

BACKGROUND: Many patients suffering from peripheral arterial disease (PAD) are dependent on bypass surgery. However, in some patients no suitable replacements (i.e. autologous or prosthetic bypass grafts) are available. Advances have been made to develop autologous tissue engineered vascular grafts (TEVG) using endothelial colony forming cells (ECFC) obtained by peripheral blood draw in large animal trials. Clinical translation of this technique, however, still requires additional data for usability of isolated ECFC from high cardiovascular risk patients...

INTRODUCTION: Despite the BASIL-1 trial concluding that bypass surgery (BS) was superior to plain balloon angioplasty (PBA) in terms of longer-term amputation free (AFS) and overall survival (OS), CLTI patients are increasingly offered an endovascular-first revascularization strategy. This study investigates whether the results of BASIL-1 are still relevant to current practice by comparing femoro-popliteal (FP) BS with PBA in a series of CLTI patients treated in our unit 10 years after BASIL-1 (1999-2004)...

BACKGROUND:  Due to its very aggressive nature and low survival chances, the metastasized urothelium carcinoma poses a challenge in regard to therapy. The gold-standard chemotherapy is platinum based. The therapy options are considered controversial, including new systemic therapies. In this respect, surgical therapies, as already established for pulmonary metastases of other tumor entities play an increasingly important role. The consumption of nicotine is a risk factor not only for urothelium carcinoma but also for a pulmonary carcinoma...

BACKGROUND: The regeneration response of the skin to mechanical stretching in vivo has been explored in reconstructive surgery to repair large-scale deformities. The ability of the skin to regenerate limits the reconstructive outcome. Here, we propose an approach in which autologous stromal vascular fraction (SVF) cells and mechanical stretching are combined to overcome this limitation and promote skin regeneration. METHODS: This randomized, blinded, placebo-controlled clinical trial screened 22 participants undergoing tissue expansion with exhausted regeneration...

Focal therapy (FT) is a promising alternative to definitive therapy for localized prostate cancer (PCa). Rather than simply monitoring cancer through active surveillance (AS) or risking the side effects of robotic radical prostatectomy (RP) it offers an intermediate solution. Azzouzi et al. examined vascular-targeted photodynamic therapy (PDT) for PCa. In this randomized, controlled clinical trial, patients with low-risk and localized PCa with no prior treatment were either assigned to a group undergoing vascular-targeted photodynamic therapy or to another group undergoing AS...
