Surgical resection of the esophagus requires sacrificing a long portion of it. Its replacement by the demanding gastric pull-up or colonic interposition techniques may be avoided by using short biologic scaffolds composed of decellularized matrix (DM). The aim of this study was to prepare, characterize, and assess the in vivo remodeling of DM and its clinical impact in a preclinical model. A dynamic chemical and enzymatic decellularization protocol of porcine esophagus was set up and optimized. The resulting DM was mechanically and biologically characterized by DNA quantification, histology, and histomorphometry techniques...

Pulmonary hypertension is defined as a mean pulmonary arterial pressure ≥25 mmHg. We focus on its relevance in congenital heart disease, reviewing pathophysiology, diagnosis and management. Pulmonary hypertension is a relatively common complication of congenital heart disease, with adult prevalence between 5 and 10%. A multifactorial cause is recognized, relating to the size and nature of cardiac defect as well as environmental and genetic factors. More complex disease is increasingly recognized rather than pure Eisenmenger complex...

N-butyl-2 cyanoacrylate (NBCA) is a liquid embolic material that is widely used in various endovascular procedures because of its permanent and rapid vascular occluding effect regardless of the coagulation profile of the patient. However, NBCA migration to unintended vessels may result in serious complications. This report describes the retrieval of a migrated NBCA cast from the transverse-sigmoid sinus during dural arteriovenous fistula embolization using a transvenous snaring technique.

BACKGROUND: Intrauterine fetal demise (IUFD) is an unpredictable and challenging obstetric complication. Its etiology is multifactorial with more than 60% attributed to the placental cause. The present study was done with a primary objective of understanding the placental lesions underlying IUFD. METHODS: In this retrospective observational study, IUFD cases (> 22 weeks) between January 2012-September 2015 were collected from pathology database. The clinical details with ultrasound findings were collected from mother's charts...

Due to advances in neoadjuvant therapies and preoperative imaging modalities, joint-sparing resections have become appealing in bone tumor surgery. However, the intercalary reconstruction of metadiaphyseal bone defects of the femur and the tibia after juxta-articular tumor resection remains challenging. Both biological and prosthetic reconstructions have been used for joint-sparing resections, but little is known about the long-term outcome of these procedures. The authors reviewed a consecutive series of 64 patients treated with joint-sparing intercalary resection and reconstruction with bone grafts...

The discovery of MODY (Maturity-Onset Diabetes of the Young) and the elucidation of its heritability enabled more precise clinical characteristics of different MODY subtypes and led to understanding that glucokinase MODY (GCK-MODY) is not associated with vascular complications in long term follow-up, whereas MODY of transcription factors (e.g. HNF1A-MODY) is in case of bad metabolic control connected with the acceleration of particularly microvascular complications. There is a strong evidence of the needlessness of any specific antidiabetic treatment in prognosticaly favourable GCK-MODY (except for the pregnancy)...

Intercostal artery injury during transthoracic puncture is rare but is accompanied by high rates of morbidity and mortality. We report a case with metachronous double primary esophageal cancers and development of multiple lung nodules. Tissue proof for the lung nodules is required to guide the following treatment protocol. Our patient died soon after computed tomography-guided lung tumor biopsy was performed, as a result of procedure-related massive and uncontrolled hemothorax. The cause is likely intercostal artery injury related to the transthoracic puncture...

Globally ~435 million people have diabetes [1], and an estimated 19-34% (~83-148 million people) of those will be expected to develop foot ulcers in their lifetime [2]. Foot ulcers are typically precipitated by other diabetes-related lower-extremity complications, (DRLECs) including peripheral neuropathy and peripheral vascular disease [2,3]. Collectively, DRLECs are a leading cause of infection, hospitalization and amputation outcomes [2-5], yet, these outcomes are readily preventable with evidence-based care [6,7]...

BACKGROUND: Although evidence supports that the performance of drug coated balloons seems to be lesion complexity independent, it is quite clear that in long lesions, severe calcified lesions and chronic total occlusions, the bail out stent ratio is very high and that the "leaving nothing behind" strategy remains a dream in a lot of our daily cases. On the other side of the spectrum, "full metal jackets" of nitinol stents are creating even more problems. Stent fractures, intimal hyperplasia and reintervention difficulties complicate the recurrent vascular disease treatment...

Hereditary pancreatitis (HP) is a progressive disease that can manifest in childhood with debilitating, relapsing pain. A total pancreatectomy and islet autotransplant (TPIAT) is a surgical option to relieve chronic pain while preserving the available beta-cell mass. The clinical course of HP is fraught with pancreatitis-related sequelae that can both necessitate and complicate a TPIAT. We describe a child with HP who developed a pancreatic pseudocyst-portal vein (PV) fistula. Active hemorrhage of the perforated PV into the pseudocyst and PV thrombosis complicated the planned TPIAT procedure and, preoperatively, required urgent image-guided stenting...

BACKGROUND: Although laparoscopic liver resection is widely performed, many technical difficulties remain, such as accurate isolation/division of hepatic vessels in laparoscopic right hepatectomy (LRH). Innovative surgical devices, such as three-dimensional (3D) laparoscopy and optimized carbon dioxide (CO2 ) insufflation system, may help to overcome technical difficulties in LRH. The purpose of this study was to analyze the efficacy of 3D vision associated with active pneumoperitoneum maintenance in LRH...

The interaction of advanced glycation end products (AGE) and their receptors promote vascular complications of diabetes in hemodialysis (HD) patients. The soluble form of the receptor for the advanced glycation end-products (sRAGE) has been studied as a vascular biomarker in various diseases with controversial results. Our aim was to evaluate the association of the serum levels of the AGEs and their receptor sRAGE with cardiovascular disease (CVD) and the cardiovascular risk factors among HD patients. There were 130 HD patients and 80 age and gender matched control subjects were involved; 31...

A new surgical technique of intra-tumoural ligation for the treatment of low-flow vascular malformations in the head and neck region is proposed. Ninety patients with diffuse low-flow vascular malformations diagnosed clinically and/or radiologically were treated surgically with the corset suturing technique. All patient records and clinical photographs were reviewed retrospectively. Significant clinical results were obtained: a reduction of the turnout tumour mass and a return of the regional facial outline was evident within 4 weeks after surgery...

OBJECTIVES: Systemic sclerosis (SSc) is an intractable connective tissue disease that causes skin and organ fibrosis. Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) affect its prognosis. YKL-40 protein impacts inflammation and tissue remodeling. Therefore, we evaluated the utility of YKL-40 blood levels in identifying patients with SSc complicated by PAH, as confirmed by immunohistochemistry (IHC) examination. METHODS: We retrospectively analyzed 78 patients with SSc and performed IHC on 7 normal and 7 SSc skin samples in the Japanese population...

Porphyromonas gingivalis (Pg), is an important periodontal pathogen that is also implicated in pregnancy complications involving defective deep placentation (DDP). We hypothesized that Pg invasion of the placental bed promotes DDP. Pregnant rats were intravenously inoculated with sterile vehicle, Pg strain W83, or A7436 at gestation day (GD) 14 (acute cohort). Non-pregnant rats received repeated oral inoculations for 3 months before breeding (chronic cohort). Tissues and/or sera were collected at GD18 for analysis...

Solitary spinal epidural cavernous angiomas are rare vascular malformations. Surgical excision is the treatment of choice, as these lesions tend to grow or bleed at some point. In this 3-dimensional, narrated video, we present the case of a 61-year-old male who presented with progressive pain in the right paravertebral region secondary to an epidural cavernous angioma located at the T6/T7 level. Under intraoperative neurophysiological monitoring, a laminectomy between T5 and T7 was performed. A reddish, well delimited, and highly vascularized epidural mass was identified and dissected from the adjacent dura and nerve root, and an en bloc total resection was achieved...

Exostoses or osteochondromas are benign osseous tumors that develop on the bone surface and can be sporadic or hereditary. Their evolution is generally benign but they may be complicated in some patients by conflicts with the surrounding nervous or vascular structures, in particular arteries. We report a case of false aneurysm of the popliteal artery secondary to an isolated exostosis of the left femur in a 20-year-old young woman. A delay in the diagnosis allowed the development of the false aneurysm which was at the origin of a major venous compression...
