Persistent embryonic veins represent a major source of venous hypertension and morbidity in venous malformation syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevus, and skeletal deformities syndrome. Surgical stripping and phlebectomy are the most commonly reported alternatives to compression therapy for refractory cases. These techniques, although effective in those patients who meet the necessary anatomic criteria, can be associated with bleeding, wound-related complications, and recurrence...

OBJECTIVE: The ACTitouch (AT) device (Tactile Medical, Minneapolis, Minn) represents a new generation of pneumatic compression devices by combining sustained compression with intermittent pneumatic compression. The sustained compression mode provides automatic pressure adjustment every 30 minutes, ensuring pressure consistency regardless of leg volume changes and environmental influences. Designed for mobile patients, this device has not been studied in comparison to standard compression stockings (CS)...

BACKGROUND: The Vascular Quality Initiative (VQI) Varicose Vein Registry (VVR) represents a patient-centered database launched in January 2015. Previous work describing overall trends and outcomes of varicose vein procedures across the United States demonstrates a benefit from these procedures. The existing gaps in evidence to support current and future Medicare coverage of varicose vein procedures necessitate further description of clinical outcomes in patients ≥65 years old compared with the population <65 years old...

Over the years, squamous cell carcinomas (SCC) that mimicked vascular lesions have been encompassed within different classifications and the underlying etiopathogenic mechanisms have been interpreted in different ways by different authors. Here, we present a case of SCC with pseudovascular areas in the right leg of a 96-year-old woman with chronic venous insufficiency. Histopathological examination closely resembled an angiosarcoma, but the immunohistochemical negativity for endothelial markers and the strong positivity for the pancytokeratin marker AE1/AE3 revealed the epithelial nature of the neoplasm...

Mechanochemical ablation (MOCA) is a nonthermal nontumescent technique used in the treatment of superficial venous disease. This review analyzed the available data on the efficacy and safety of MOCA. A systematic literature search was performed. Of 101 studies identified, 14 were suitable for inclusion. The studies were found to be heterogeneous in design, and the quality of evidence was found to be low or very low. MOCA was demonstrated to be effective in the short-term with minimal complications. Consensus guidelines and definitions of reporting outcome measures must be standardized to allow comparison with other techniques...

In venous disease, acute thromboses and chronic venous insufficiency have the highest health economics relevance. Duplex sonography is the first line diagnostic assessment tool, while cross-sectional imaging is employed as a supplementary method. Due to the availability and examination times computed tomography is preferred in the emergency setting and is supplemented by magnetic resonance imaging (MRI) for specific questions. Endovascular treatment procedures are increasingly becoming available in addition to classical conservative treatment methods...

Most femoral artery arteriovenous fistulas occur as a result of percutaneous interventions. However, arteriovenous fistulas can occur in the setting of trauma, with resultant consequences such as heart failure, steal syndrome, or venous insufficiency. Indications for endovascular repair in this setting are limited to patients who are at too high risk for anesthesia, have a hostile groin, or would not survive significant bleeding. We report the case of a traumatic femoral arteriovenous fistula, causing severe venous insufficiency and arteriomegaly, in a 58-year-old male, with history of traumatic gunshot wound complicated by popliteal DVT...

Inferior vena cava (IVC) anomalies were rare and usually asymptomatic. Among these, anomalies absence of infra-renal IVC is the rarest anomaly. Absence of infra-renal IVC may present with symptoms of venous insufficiency and idiopathic deep vein thrombosis. Contrast enhanced CT and MRI abdomen play crucial role in diagnosing these anomalies. These patients can be managed conservatively or by venous bypass. Identification of these anomalies is important to avoid surgeries for varicose veins.

The endovenous laser ablation (EVLA) of the insufficient saphenous vein has similar results to open conventional surgery, but less morbidity. The echo-guided polidocanol foam sclerotherapy technique has been used for the same purpose. The combined techniques may play a role for more severe diseases, such as those with varicose ulcers. An EVLA device (called VELAS) has been developed in the Optics and Photonics Research Center of USP-São Carlos in agreement with FMB-UNESP. In this study, we present the preliminary results of the VELAS device (MMO 980nm diode) in patients with chronic venous ulcer, associated with echo-guided polidocanol foam sclerotherapy for the treatment of varicosities...

One of the widely accepted adjunctive agents in the variety of surgical modalities are sealants. Our study aim was to compare four commonly used modern sealants in a standardized experimental setting to assess their feasibility, and hemostatic efficacy in vascular anastomosis. Forty landrace pigs (weight: 24.7 ± 3.8 kg) were randomized into the control (n = 8) and four sealant groups; TachoSil® (n = 8), Tissucol Duo® (n = 8), Coseal® (n = 8), and FloSeal® (n = 8). After doing a portal vein end-to-end anastomosis as well as stitches of aortic incision, the sealants were applied on anastomotic site...

During endovenous ablation for the treatment of insufficient veins, failure to cannulate the entirety of the refluxing vein with the treatment catheter prevents technically successful ablation. In this technique report, we describe a defined protocol to overcome cannulation failure of axial veins for endovenous ablation. This protocol utilizes commonly available adjunctive techniques including ultrasound-guided digital compression, the use of a guide wire, the use of a guide catheter, and placement of a second puncture site in a step-wise fashion to overcome varying degrees of tortuosity or obstruction...

OBJECTIVES: To assess whether reversing the veno-arterial extracorporeal membrane oxygenation blood flow (thereby creating a controlled arterio-venous shunt) can be used to wean children off extracorporeal membrane oxygenation. The standard practice for weaning patients off VA extracorporeal membrane oxygenation is to gradually reduce the blood flows delivered through the extracorporeal membrane oxygenation pump to a minimum level followed by either insertion of an "arterio-venous bridge" and clamping of the blood flow to the patient or direct decannulation...

BACKGROUND: Refinements in microsurgery have made distal finger replantation an established technique with high success rates and good functional and aesthetic outcomes. However, it still represents a technically demanding procedure due to the small vessel caliber and frequent lack of vessel length, requiring the use of interpositional venous grafts in some instances. We describe a new technique for anastomosis in fingertip replantation, whereby the need for venous grafts is eliminated...

Post-thrombotic syndrome (PTS) is a complication that develops in up to 50% of patients with deep vein thrombosis (DVT) and manifests as symptoms and signs of chronic venous insufficiency of varying severity. PTS negatively affects patient's quality of life and causes significant burden to the healthcare system. The risk for PTS development can be markedly reduced by preventing DVT and providing appropriate anticoagulation once it develops. Patients with extensive proximal (iliofemoral) DVT may benefit from invasive interventions, such as catheter-directed thrombolysis...

BACKGROUND: The efficacy of cold in situ perfusion and static storage of the liver is one possible determinant of transplantation outcomes. The aim of this study was to determine whether there is evidence to substantiate a preference for a particular perfusion route (aortic or dual) or perfusion/preservation solution in donation after brain-death (DBD) liver transplantation. METHODS: The Embase, Medline and Cochrane databases were utilized (1980-2017). Random effects modeling was used to estimate effects on transplantation outcomes based upon (i) aortic or dual in situ perfusion, and (ii) the use of University of Wisconsin (UW), histidine-tryptophan-ketoglutarate (HTK), Celsior and/or Institut Georges Lopez-1 (IGL-1) for perfusion/preservation...
