Aortic graft infection is one of the most serious complications of aortovascular surgery. Diagnosis is based on clini-cal and radiologic findings. The emphasis is put on early diagnosis and its impact on prognosis of patients. The management should be individualized. The gold standard is surgical treatment with complete excision of the infected foreign material with debridement of the surrounding tissue and repair of vascular continuity by extra-anatomic bypass or in situ bypass with autologous femoral vein or cryopreserved arterial allografts...

STUDY QUESTION: Do cell adhesion molecules play a role in endometriosis, and can they be used as a biomarker for diagnosing endometriosis? SUMMARY ANSWER: Altered expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) in the endometrium and peritoneum may play a key role in endometriosis and the soluble VCAM-1/soluble ICAM-1 ratio is a promising biomarker. WHAT IS KNOWN ALREADY: Cell adhesion molecules are cell surface proteins that mediate cellular adherence, inflammatory and immune responses, and cancer-related biological processes...

Objectives: To identify the risk factors associated with Candida auris candidaemia, as this fungus now poses a global threat. Methods: We performed a subgroup analysis of a previously reported study of 27 Indian ICUs. The clinical data of candidaemia cases due to C. auris and other Candida species were compared to determine significant risk factors associated with C. auris infection. Results: Of the 1400 candidaemia cases reported earlier, 74 (5...

The thyroid is a rare site of clinically detectable tumor metastases; even though the gland is a highly vascularized structure, the frequency of metastases in the routine practice is less than 0.2% of all thyroid malignancies. The purpose of our meta-analysis is to evaluate the frequency of metastatic diffusion from other primary tumors to the thyroid gland and to suggest the best possible treatment through an evidence-based study. Relevant studies were identified by searching the following databases: PubMed, Scopus, and Web of Science...

Ricardo Badillo, Michael D Darcy, Vladimir M Kushnir
We discuss a patient with late presentation of hemobilia following cholecystectomy, which is unusual because pseudoaneurysm caused by vascular injury during surgery typically presents soon after surgery. Endoscopic retrograde cholangiopancreatography revealed a large blood clot arising from the biliary orifice with subsequent computed tomography angiography diagnosing a large pseudoaneurysm in the region of the cystic artery adjacent to the cholecystectomy clips. Embolization was performed via direct percutaneous puncture of the pseudoaneurysm...

BACKGROUND: In cases of chronic thromboembolic pulmonary hypertension (CTEPH), referral for possible surgical intervention is important because surgery can be curative. Surgery necessitates cardiopulmonary bypass and deep circulatory arrest with pulmonary thrombectomy and bilateral endarterectomy (PTE). If surgery fails, lung transplant is the next best surgical option. Medical treatment is also an important adjunct. CASE REPORT: A 35-year-old female presented 3 months after a pulmonary embolus was found to be completely occluding her left pulmonary artery...

PURPOSE: To report a patient whose foveal avascular zone (FAZ) decreased after vitrectomy with internal limiting membrane (ILM) peeling. METHODS: A 58-year-old woman underwent successful phacovitrectomy with ILM peeling for a thin epiretinal membrane in an eye with a normal foveal contour. Optical coherence tomography angiographic en face images of the 3 mm×3 mm superficial and deep inner retinal vascular plexuses were examined preoperatively, and on days 1, 2, 9, and 37 postoperatively...

PURPOSE: Minimally invasive surgery is in constant further development and has replaced many conventional operative procedures. If vascular structure movement could be detected during these procedures, it could reduce the risk of vascular injury and conversion to open surgery. The recently proposed motion-amplifying algorithm Eulerian Video Magnification (EVM) has been shown to substantially enhance minimal object changes in digitally recorded video that is barely perceptible to the human eye...

Glomus tumor is a rare benign vascular hamartoma derived from the modified smooth muscle cells of the glomus body. Paroxysmal pain is the leading symptom. A 78-year-old woman presented at our clinic with a 50-year history of a slow growing painful purple blue tender nodule under the right fourth finger nail. Dermoscopy and magnetic ressonance confirmed the presence of a large subungual tumor and total surgical excision was performed after partial nail plate avulsion. Histologic examination confirmed a glomus tumor...

Vascularized composite allotransplantation (VCA) has demonstrated utility in the reconstruction of extensive soft-tissue defects following severe burns. However, pre-VCA events such as multiple transfusions, previous transplantation and pregnancies, the use of skin allografts, and mechanical support devices may result in sensitization and ultimately exclude a burn patient, who may benefit most through VCA, from a hand or face transplant. The authors sought to identify the immunologic challenges involved. All reported VCA cases up to July 2016 were reviewed...

Ablative surgery of mandible often necessitates combined reconstruction of the mandible and the temporomandibular joint. Fibula-free flaps with gap arthroplasty or osseochondral grafts are common procedures in the authors' practice. In search for a better reconstructive option free fibula flap is used together with a metatarsal bone flap for the vascular reconstruction of the mandibular body and the condyle at the same time. The 2 osseous-free flaps have been fused and used as a combined flow through double-free flap...

BACKGROUND: The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. OBJECTIVE: To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. METHODS: Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. RESULTS: Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished...

BACKGROUND: Margin-free en bloc resection is the best medical practice for primary vertebral chordoma and chondrosarcoma. Spinal reconstruction following total spondylectomy requires reconstructive interbody graft (allograft, devascularized autograft, vascularized autograft, or cage constructs) and instrumentation. An important consideration when choosing grafts and instrumentation is the durability and the long-term success of the fusion without subsidence. OBJECTIVE: To evaluate the potential use of vascularized fibular autograft as a reconstructive strategy after en bloc resection...

Background: Despite knowing that resveratrol has effects on blood vessels, blood pressure and that phytostrogens can also improve the endothelium-dependent relaxation/vasodilation, there are no reports of reveratrol's direct effect on the endothelial function and blood pressure of animals with estrogen deficit (mimicking post-menopausal increased blood pressure). Objective: To verify the effect of two different periods of preventive treatment with resveratrol on blood pressure and endothelial function in ovariectomized young adult rats...

Oral and maxillofacial surgery in veterinary medicine carries the risk of severe hemorrhage due to the great vascular supply of the head. Temporary hemostasis can be achieved with the application of pressure or hemostatic agents, but more definitive treatment may be needed to ensure bleeding will not resume once the patient is awake and normotensive. (1 , 2) Actively bleeding vessels encountered during maxillofacial surgery may be inaccessible, and vessels may recoil into bone, sometimes preventing definitive ligation...

Angiosarcomas are highly aggressive malignancies of vascular origin and are very rarely found in children. We report a case of a 13-year-old girl with a history of abdominal pain and increased abdominal girth. Radiologic imaging showed significant ascites and large pelvic masses involving bilateral adnexa with abdominal spread. Microscopic examination of a biopsy revealed pleomorphic epithelioid and spindle cells with brisk mitotic activity, intracytoplasmic vacuoles, vascular channels, and large areas of hemorrhage and necrosis...

The creation of an arteriovenous fistula (AVF) is a common surgical procedure in hemodialysis patients suffering from end-stage renal disease (ESRD). However, several complications may occur after surgery, including thrombosis, stenosis, and aneurysm. These complications are attributed to hemodynamics perturbations including pathophysiological wall shear stress (WSS) and flow recirculation zones. In this study, we present a computational hemodynamic analysis in a model of a mature side-to-side AVF, which is then validated by experimental measurements...

BACKGROUND: Pediatric congenital heart disease patients are at risk for vascular injuries during surgical procedures or when the arterial system is accessed for monitoring or diagnostic studies. Our treatment of emergent situations in this patient population using microvascular techniques shows the feasibility of such techniques. METHODS: A retrospective chart review of patients aged 0-18 years with congenital heart disease identified six patients who underwent microvascular surgery by the senior surgeon from June 2007 to May 2015...

Mesenchymal stem cells (MSCs) represent a promising alternative source for cartilage tissue engineering. However, MSC culture is labor-intensive, so these cells cannot be applied immediately to regenerate cartilage for clinical purposes. Risks during the ex vivo expansion of MSCs, such as infection and immunogenicity, can be a bottleneck in their use in clinical tissue engineering. As a novel stem cell source, pericytes are generally considered to be the origin of MSCs. Pericytes do not have to undergo time-consuming ex vivo expansion because they are uncultured cells...
