We report an extremely low-birth-weight neonate who developed umbilical artery perforation and false tracking. There was no life-threatening event relating to the complication. Diagnosis was made at postmortem examination. Little information exists regarding the anatomic and vascular effects of umbilical artery catheterization placement in newborns. We report a new complication of umbilical artery catheterization. We raise the awareness regarding the potential life threat due to this rare but very serious complication...

The cellular mechanisms underlying the microvascular dysangiogenesis of bronchopulmonary dysplasia (chronic lung disease of the newborn) remain largely undetermined. We report unusual pulmonary vascular findings in a 27-week-gestation male newborn who died on the second day of life from intractable respiratory failure, following a pregnancy complicated by prolonged membrane rupture and persistent severe oligohydramnios. As expected, postmortem examination revealed pulmonary hypoplasia (lung/body weight ratio: 2...

BACKGROUND: Laparoscopic complete mesocoloic excision (CME) with central vascular ligation for splenic flexure cancer is technically challenging because of its anatomical complexity. Although embryological and anatomical consideration should be helpful to perform CME in colorectal cancer surgery, such studies on the splenic flexure are lacking. METHODS: The splenic flexure is located embryologically between the terminal portion of the midgut and the beginning of the hindgut, and is supplied by the superior mesenteric and inferior mesenteric arteries...

PURPOSE: Surgical treatment of head and neck malignancies frequently includes microvascular free tissue transfer. Preoperative radiotherapy increases postoperative fibrosis-related complications up to transplant loss. Fibrogenesis is associated with re-expression of embryonic preserved tissue developmental mediators: osteopontin (OPN), regulated by sex-determining region Y‑box 9 (Sox9), and homeobox A9 (HoxA9) play important roles in pathologic tissue remodeling and are upregulated in atherosclerotic vascular lesions; dickkopf-1 (DKK1) inhibits pro-fibrotic and atherogenic Wnt signaling...

Heparin has typically been used as a flushing or infusion solution for vascular lines in daily practice. However, several clinical trials have yielded controversial results about the benefits of heparin in maintaining peripheral venous catheters. The present meta-analysis was conducted to evaluate the efficacy of heparin on the patency profiles and complications in peripheral intravenous catheters. PubMed, Embase and Cochrane Central Register of Controlled Trials were searched up to February 2016 for randomized controlled trials comparing heparin with placebo in maintaining peripheral intravenous catheters...

SUDOSCAN is a non-invasive method of measuring peripheral small fiber and autonomic nerve activity by detection of abnormal sweat gland function through electrochemical skin conductance. It has been reported to be an effective screening tool in early detection of microvascular type 2 diabetes mellitus (T2DM) complications including diabetic neuropathy and nephropathy in recent studies. However, previous studies used estimated glomerular filtration rate (eGFR) as the golden standard, which has a 90% chance of being within 30% of the measured GFR at best...

Diabetic vasculopathy is intensified by macrophage inflammation caused by advanced glycation end products (AGEs). Heparanase (HPA) is a unique endoglycosidase, which cleaves heparan sulfate proteoglycans (HSPGs) including syndecan-1 (Syn-1) to further stimulate macrophage cell migration and inflammation. The present study was planned to evaluated the role of C-domain (if any) of HPA in AGE inflammatory response in macrophages. Cell viability was assessed using MTT assay, migration assay, ELISA for tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels, mRNA expression by RT-PCR and heparan degrading enzyme assay for HPA activity...

The aim of this work was to evaluate the effects of glucagon-like peptide-1 (GLP-1) on high-glucose-induced oxidative stress and investigate the possible mechanisms underlying this process. We measured reactive oxygen species (ROS) production, cell apoptosis, the expression of NOX4 and its subunits, and p47phox translocation in human umbilical vein endothelial cells (HUVECs). An experimental type 2 diabetes model was induced using streptozotocin in male Sprague-Dawley rats. Fasting blood glucose (FBG), fasting insulin (FINS), total cholesterol (TC), triglycerides (TGs), and free fatty acid (FFA) were measured...

BACKGROUND AND OBJECTIVES: Psoas blocks are an alternative to femoral nerve blocks and have the potential advantage of blocking the entire lumbar plexus. However, the psoas muscle is located deeply, making psoas blocks more difficult than femoral blocks. In contrast, while femoral blocks are generally easy to perform, the inguinal region is prone to infection. We thus tested the hypothesis that psoas blocks are associated with more insertion-related complications than femoral blocks but have fewer catheter-related infections...

REVIEW
Magdalena Krajewska-Włodarczyk, Tomasz Stompór
Disorders of bone tissue metabolism and increased frequency of cardiovascular diseases are among the well-known, extra-articular complications of rheumatoid arthritis (ra). The mechanisms leading to local and generalized loss of bone tissue as well as those promoting calcification of vessels are similar. Recently, a great interest has aroused among the studies related to the meaning of the RANKL/RANK/OPG system and the Wnt/β-catenin signaling pathway, as biological links between the bone and vascular systems...

Inadvertent anastomosis of the left internal mammary artery (LIMA) or a saphenous vein graft (SVG) to the great cardiac vein (GCV) is a rare complication of coronary artery bypass grafting (CABG). We present two cases with a LIMA to GCV and a SVG to GCV anastomosis, respectively, resulting in angina and dyspnea in the postoperative state. As an alternative to repeat CABG, both patients underwent percutaneous coronary intervention with percutaneous coil embolization or implantation of an Amplatzer vascular plug within the bypass graft to GCV conduit...

True peripheral artery aneurysms proximal to a longstanding arteriovenous fistula is a well-recognized complication. Late aneurysmal degeneration is rare. This study analyzed the characteristics, therapeutic options, and outcomes of true donor brachial artery aneurysms (DBAA) after arteriovenous fistula (AVF) for hemodialysis. We retrospectively collected the data of patients with DBAA after AVF creation, surgically repaired between January 2001 and September 2015. We excluded patients with pseudoaneurysms, anastomotic aneurysms, and infected aneurysms...
