Iliopsoas abscess is a rare condition with a high rate of mortality and morbidity if left untreated. It can occur from hematogenous or lymphatic spread from distant structures or as a result of contiguous spread from adjacent structures. The disease typically occurs in patients with immunocompromised status and the symptoms can be non-specific.1,2 Generally, infectious complications from venous access during atrial fibrillation (AF) procedure are uncommon, and an iatrogenic iliopsoas abscess from percutaneous cardiac procedures has never been reported...

BACKGROUND: Short (or small) saphenous vein (SSV) varices occur as a result of an incompetent sapheno-popliteal junction, where the SSV joins the popliteal vein, resulting in reflux in the SSV; they account for about 15% of varicose veins. Untreated varicose veins may sometimes lead to ulceration of the leg, which is difficult to manage. Traditionally, treatment was restricted to surgery or conservative management. Since the 1990s, however, a number of minimally invasive techniques have been developed; these do not normally require a general anaesthetic, are day-case procedures with a quicker return to normal activities and avoid the risk of wound infection which may occur following surgery...

The liver function may be degraded after partial liver ablation surgery. Adverse liver hemodynamics have been shown to be associated to liver failure. The link between these hemodynamics changes and ablation size is however poorly understood. This article proposes to explain with a closed-loop lumped model the hemodynamics changes observed during twelve surgeries in pigs. The portal venous tree is modeled with a pressure-dependent variable resistor. The variables measured, before liver ablation, are used to tune the model parameters...

OBJECTIVE: To identify which deep anatomical anomalies can explain variable hemodynamic outcomes in patients with superficial reflux associated with primary deep axial reflux who underwent isolated superficial vein ablation without improvement. METHODS: This is a retrospective study of deep venous valve anomalies in patients who underwent superficial vein ablation for superficial and associated deep reflux. A group of 21 patients who were diagnosed with saphenous reflux associated with primary deep axial reflux, were submitted to great saphenous vein ablation...

Varicose veins of the lower extremity (VVLE) are a frequently encountered vascular disorder in the general population. The general view that VVLE are a non-serious disease with primarily aesthetic impact is a common misconception, as the disease can have a significant negative impact on generic and disease-specific quality of life. Further, VVLE may be associated with potentially threatening clinical conditions, such as chronic venous ulceration, venous thromboembolism and haemorrhage from ruptured varicose veins...

REVIEW
Robert C G Martin
The diagnosis for locally advanced pancreatic cancer is based on high-quality cross-sectional imaging, which shows tumor invasion into the celiac/superior mesenteric arteries and/or superior mesenteric/portal venous system that is not reconstructable. The optimal management of these patients is evolving quickly with the advent of newer chemotherapeutics, radiation, and nonthermal ablation modalities. This article presents the current status of initial chemotherapy, surgical therapy, ablative therapy, and radiation therapy for patients with nonmetastatic locally advanced unresectable pancreatic cancer...

INTRODUCTION: A lack of information about the feasibility and safety of leadless pacemaker (LPMs) exists in a fragile population of patients with limited venous anatomy access or conventional pacemaker (PM) contraindication. Accordingly, the goal of this prospective observational study was to report our experience with this new leadless technology in a subset of patients with contraindication or limited venous access. METHODS AND RESULTS: Between May 2015 and July 2016, 14 patients were consecutively included...

Vascular networks surrounding individual organs are important for their development, maintenance, and function; however, how these networks are assembled remains poorly understood. Here we show that CNS progenitors, referred to as radial glia, modulate vascular patterning around the spinal cord by acting as negative regulators. We found that radial glia ablation in zebrafish embryos leads to excessive sprouting of the trunk vessels around the spinal cord, and exclusively those of venous identity. Mechanistically, we determined that radial glia control this process via the Vegf decoy receptor sFlt1: sflt1 mutants exhibit the venous over-sprouting observed in radial glia-ablated larvae, and sFlt1 overexpression rescues it...

PURPOSE: To report the midterm results of mechanochemical ablation (MOCA) for treating great saphenous vein (GSV) insufficiency. METHODS: In a 1-year period, 85 consecutive patients (median age 51.4 years; 71 women) undergoing MOCA with polidocanol in 104 limbs were enrolled in a prospective registry. The patients were evaluated at baseline and during follow-up (4 weeks and 1, 2, and 3 years) using duplex ultrasound, the CEAP (clinical, etiologic, anatomic and pathophysiologic) classification, the Venous Clinical Severity Score (VCSS), the RAND Short Form 36-Item Health Survey (RAND-SF36), and the Aberdeen Varicose Vein Questionnaire (AVVQ)...

We performed a comparative study of surgical outcomes and venous functions between endovenous laser ablation with a 980-nm diode laser (EV group) and thigh stripping (ST group). There were no severe complications and initial success rates were 100% in both groups. In the EV group, preoperative symptoms improved in 94.3% of cases, the venous occlusion rate was 98%, and endovenous heat induced thrombosis had occurred in 11.9% (Class 3: 0.7%) at 12 months after the operation. Although comparative study of postoperative venous function by air plethysmography showed significant improvement in both groups, there was less recovery of postoperative venous function in the EV than in the ST group...

Modern management of varicose veins Chronic venous disease is a common medical condition and occurs in about one-third of the adult population. Reflux, and to a much lesser extent obstruction of the superficial and deep venous systems, generates venous hypertension. The goal of the treatment is to reduce venous hypertension in order to prevent complications, progression of venous disease and to improve patients' quality of life. Today we have a wide spectrum of different treatment options at our disposal. Management is based upon accurate clinical diagnosis and duplex imaging...

AIMS: The effectiveness of atrial fibrillation (AF) ablation relies on detailed knowledge of the anatomy of the left atrium (LA) and pulmonary veins (PVs). It is common to combine computed tomography/magnetic resonance (CT/MR) with imaging by electroanatomical (EA) mapping systems. The aim of this study was to evaluate the accuracy of LA anatomical reconstruction by 'One Model' and 'VeriSense' tools (Ensite Velocity 3.0, St Jude Medical), compared with CT/MR imaging. METHODS AND RESULTS: Seventy-two patients with AF underwent pre-procedural imaging (97% CT-scan, 3% MR imaging) and transcatheter ablation of PVs...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

BACKGROUND: After ablation of Barrett's esophagus (BE), the esophagus heals with neosquamous epithelium (NSE). Despite normal endoscopic appearance, NSE exhibits defective barrier function with similarities to defects noted in the distal esophageal epithelium in patients with gastroesophageal reflux disease (GERD). AIM: To determine whether patients with NSE, unlike patients with healthy esophageal epithelium, have C-terminal fragments (CTFs) of e-cad detectable on tissue biopsy...

AIM: In the 7th edition of the TNM classification, not only HCC with distant metastases but also those with regional lymph node metastases are classified as stage IV. MATERIALS AND METHODS, RESULTS: From our prospectively recorded tumor registry, 138 patients (17 %) with HCC were in stage IV. Among those were 68 and 70, respectively, in stage IVA (regional lymph node metastases) and IVB (distant metastases). The tumors were less frequently treated with resection or local ablative treatment (chemoembolization, RFA, SIRT, percutaneous radiation) than patients in stage I-III...
