BACKGROUND: Visible leg veins are not only a mere aesthetic problem, but may also be manifestation of altered microcirculation and superficial venous incompetency. Sclerotherapy is the first-line treatment for leg veins < 4 mm, but it often needs multiple sessions and sometimes fails. The main limitations of transcutaneous laser treatment are the diameter and the depth of the veins: the greater, the harder photothermolysis is, so that higher powers may lead to aesthetic complications...

We propose the visualization of venous compliance (VC) using a digital red-green-blue (RGB) camera. The new imaging method, which transforms RGB values into VC, combines VC evaluation with blood concentration estimation from the RGB values of each pixel. We evaluate a non-contact plethysmography (NCPG) system for VC based on comparisons with conventional strain gauge plethysmography (SPG). We conduct in vivo measurements using both systems and investigate their differences by evaluating the VC. The results show that the two methods measure different blood vessels and that errors caused by interstitial fluid accumulation are negligible for the NCPG system, whereas SPG is influenced by such errors...

BACKGROUND: Vascularized composite allotransplantation of the eye is an appealing, novel method for reconstruction of the nonfunctioning eye. The authors' group has established the first orthotopic model for eye transplantation in the rat. With advancements in immunomodulation strategies together with new therapies in neuroregeneration, parallel development of human surgical protocols is vital for ensuring momentum toward eye transplantation in actual patients. METHODS: Cadaveric donor tissue harvest (n = 8) was performed with orbital exenteration, combined open craniotomy, and endonasal approach to ligate the ophthalmic artery with a cuff of paraclival internal carotid artery, for transection of the optic nerve at the optic chiasm and transection of cranial nerves III to VI and the superior ophthalmic vein at the cavernous sinus...

Two-stage transposed brachiobasilic arteriovenous fistula is a common procedure after brachiobasilic fistula (BBF) creation. Different techniques can be used for basilic vein transposition but few comparative literature reports are available. The aim of our study was to compare two different techniques for basilic vein transposition. The first maintains the BBF anastomosis and the basilic vein is placed in a subcutaneous pocket (BBAVF). The second transects the basilic vein at the BBF anastomosis and tunnels it superficially, with a new BBF in the brachial artery (BBAVFTn)...

Basilic vein elevation (BVE) is a procedure where the basilic vein (BV) is surgically exposed, mobilized, and elevated into a more superficial position for the purpose of facilitating arteriovenous fistula (AVF) cannulation. The purpose of this study is to review the use of BVE as an adjunct to fistula maturation. Between January 2009 and December 2013, 60 patients received BVE. After performing the anastomosis between brachial artery and BV, the elevated vein was placed just anterior to the surgical incision, 3 to 4 mm deep...

Background Microcirculation is an important factor frequently overlooked when studying the survival of prefabricated flaps. In the current study, we use different prefabrication techniques for characterizing microcirculation within the flap, with the goal of finding an effective way to improve its survival area. Methods An abdominal prefabricated flap rodent model was created using a two-stage operation. All rats were randomly divided into six groups (n = 10/group): group A, prefabricated femoral vessels; group B, prefabricated femoral artery with a connected superficial inferior epigastric vein (SIEV); group C, connected superficial inferior epigastric artery (SIEA) with a prefabricated femoral vein; group D was similar to group A along with a prefabricated SIEA, and group E was similar to group A along with a prefabricated SIEV; and group F acted as a control group and consisted of an axial flap nourished by superficial inferior epigastric vessels...

PURPOSE: Convexal subarachnoid hemorrhage (cSAH) comprises less than 5% of cases of nontraumatic SAH and frequently presents as a focal and transient neurological deficits that mimics transient ischemic attack (TIA). Isolated cortical vein thrombosis (ICVT) is rare and accounts for only 6.3% of cerebral venous thrombosis. We present a case of minor stroke due to cSAH secondary to ICVT, and alos put emphasis on the chronological change of those serial imagings. CASE REPORT: An 87-year-old man presented with episodes of numbness and dropping of his left arm, which had lasted for three days...

Inadvertent complications of jugular vein catheterization are not uncommon, however, a persistent symptomatic carotid-jugular fistula has been rarely reported. A 72-year-old male with infected surgical wound after coxofemoral disarticulation for sarcoma presented with symptoms of acute right heart failure. A fistula between the right common carotid artery (CCA) and the internal jugular vein was demonstrated on Doppler ultrasound and confirmed on computed tomography angiogram. Catheterization of the right CCA seemed not possible using a conventional femoral approach due to the tortuosity and elongation of the brachiocephalic artery...

BACKGROUND Developmental venous anomalies (DVAs) are rare vascular diseases becoming more frequently diagnosed. Most patients with DVAs have no clinical symptoms with the exception of a few patients with epilepsy, intracranial hemorrhage, or neuro-function deficit. There is still controversy with respect to treatment strategies for symptomatic DVAs. MATERIAL AND METHODS Forty-three cases of symptomatic DVAs from January 2006 to October 2015 were retrospectively reviewed and the imaging characteristics of DVAs by CT, MRI, and DSA and the treatment modalities for DVAs were studied...
