Klippel-Trenaunay syndrome (KTS) is a rare, clinically variable congenital disorder involving capillary malformations, soft tissue or bone hypertrophy, and venous malformations or varicose veins. We report a 28-year-old man who presented with a hypertrophic right arm as well as markedly increased ipsilateral axillary hyperhidrosis and erythematous patches on the back, chest, and arm. This case of KTS is unusual because our patient presented with a markedly increased unilateral axillary hyperhidrosis ipsilateral to the hypertrophic limb...

BACKGROUND: The incidence of infiltration and extravasation when using peripheral intravenous catheters is high in pediatric patients. Due to the lack of a gold standard test to confirm intravascular location of a peripherally placed intravenous catheter, we introduce a novel method, the color-flow injection test to assess the intravascular location of these catheters. For the color-flow injection test, 1 mL of normal saline was injected within 2 seconds in the distal intravenous catheter and changes in color-flow via ultrasonography were observed at the proximal draining veins...

Midshaft clavicular fractures are often treated nonoperatively with good reported clinical outcome in a majority of patients. However, malunion with shortening of the affected clavicle is not uncommon. Shortening of the clavicle has been shown to affect shoulder strength and kinematics with alteration of scapular position. Whereas the exact clinical impact of these factors is unknown, the deformity may lead to cosmetic and functional impairment as for example pain with weight-bearing on the shoulder girdle...

BACKGROUND: Device reimplantation after extraction due to cardiac implantable electronic device (CIED) infection in pacemaker-dependent patients can be challenging in patients with limited access options. OBJECTIVE: We describe a straight-forward, low lateral thoracic implantation technique for patients with a patent axillary vein but unavailable bilateral pectoral sites. METHODS: We included 9 pacemaker-dependent patients (mean age 70±13, 7 male) who underwent CIED extraction and low lateral thoracic reimplant, in whom bilateral pectoral sites were unavailable...

BACKGROUND: Prostacyclins improve symptoms and survival in pulmonary arterial hypertension (PAH). In response to risks associated with external delivery systems, an implantable intravenous infusion system was developed. A multicenter, prospective, single-arm, clinical trial (DelIVery for PAH) was conducted to evaluate this system for treprostinil in PAH. This analysis describes the findings related to the implant procedure. METHODS: Patients (n=64) with PAH (WHO Group 1) receiving stable intravenous treprostinil were enrolled...

BACKGROUND: Reconstruction of postburn axillary contractures is difficult and particularly challenging without healthy adjacent soft tissue for axillary scar resurfacing. In this case, a free soft-tissue transfer is among the best treatment options. Here, we describe our experience with free anterolateral thigh (ALT) flap for reconstruction in postburn axillary contractures. METHODS: We enrolled 10 patients with postburn axillary contractures from August 2003 to July 2015...

Avoidance of hand ischemia in the construction of prosthetic access for hemodialysis in diabetics that have no suitable vein for arteriovenous fistula is appreciated. Taper type may be an appropriately matched conduit to prevent its occurrence. This is a prospective controlled trial of 38 selected diabetics requiring hemodialysis, who were referred to our clinic during a period of 6 months. The aim of the study was to evaluate the efficacy of tapered grafts in preventing distal hand hypoperfusion and determining its most likely contributors...

Although the cephalic vein follows a fairly consistent course, numerous variants have been reported. We found a rare anatomical presentation of the cephalic vein in a 75-year-old Korean male cadaver. The left cephalic vein was identified in the deltopectoral groove, ascended over the clavicle, and terminated into the left subclavian vein just before its union with the left internal jugular vein. The detailed knowledge on the variations of the cephalic vein is important for clinicians as well as anatomists since the approach through the axillary base is favored in many invasive clinical procedures...

BACKGROUND: The axillary vein is an easily accessible vessel that can be used for ultrasound-guided central vascular access and offers an alternative to the internal jugular and subclavian veins. The objective of this study was to identify which transducer orientation, longitudinal or transverse, is better for imaging the axillary vein with ultrasound. METHODS: We analyzed 236 patients who had undergone central venous cannulation of axillary vein in this retrospective study...

The quadrangular space is a space in the axilla bounded by the inferior margin of the teres minor muscle, the superior margin of the teres major muscle, the lateral margin of the long head of the triceps brachii muscle and the surgical neck of the humerus, medially. The axillary nerve (C5-C6) and the posterior circumflex humeral artery and veins pass through this space in order to supply their territories. The subscapularis muscle is situated into the scapular fossa and inserts itself into the lesser tubercle of the humerus, thus helping stabilize the shoulder joint...

The mammary gland is composed of multiple tubules acinar pockets in which the secretory layer, connective tissue stroma, and fatty tissue all respond to hormonal and systemic influences. These structures are irrigated by three vascular pedicle branches, from the axillary artery, internal mammary artery, and intercostal artery. This vascular anastomotic arrangement forms the anatomical basis of the flaps used in breast reduction techniques. The veins form a strong subdermal network, latticed with the arterial network...

We report an 84-year-old woman who presented with right ventricular perforation 4 days after pacemaker implantation for syncope due to sick sinus syndrome. Median sternotomy revealed no pericardial effusion, but the pacing lead had penetrated the right ventricle and pericardium. When the pleura was opened, the tip of the lead was seen in the visceral pleura. The lead was cut in the pericardial cavity and extracted from the left subclavian wound together with the generator. The right ventricular perforation was sutured and a temporary pacing lead was placed on the right ventricular wall intraoperatively...

OBJETIVES: The implantation of long duration intravenous catheters in pediatric population constitutes a challenge due to the size of vascular structures. Because of that, ultrasound is an important tool for vascular accesses in newborns and infants. The objective is to analyze our experience in ultrasound-guided implantation of reservoir type and tunneled catheters, as well as to compare it between both age groups. MATERIAL AND METHODS: Review of the ultrasound-guided implantable catheters placed from October 2010 to December 2014 in children under 18 months...

A 43-year-old man had a peritoneovenous shunt inserted for the treatment of chylous ascites secondary to myelofibrosis. Despite being on anticoagulation for superior mesenteric vein thrombosis, he developed shunt dysfunction within two weeks of insertion. Superior venacavography showed multiple filling defects in the right axillary vein, no filling of the right brachiocephalic and right subclavian vein, and thrombotic occlusion of the internal jugular veins bilaterally. The shunt was removed 11 days after insertion, and there was extensive thrombosis of the venous end of the shunt and the compressible pump chamber...

AIMS: A successful cephalosomatic anastomosis ("head transplant") requires, among others, the ability to control long-term immune rejection and avoidance of ischemic events during the head transference phase. We developed a bicephalic model of head transplantation to study these aspects. METHODS AND RESULTS: The thoracic aorta and superior vena cava of a donor rat were anastomosed with the carotid artery and extracorporeal veins of a recipient rat by vascular grafts...

OBJECTIVE: The primary objective was to compare the frequency of first-attempt successful axillary vein cannulation by the Seldinger technique using out-of-plane ultrasound guidance versus in-plane imaging. Between the two ultrasound imaging planes, this study also compared the number of attempts that were necessary for the cannulation of the left axillary vein along with the number of needle redirections that had to be done for final cannulation of the vein. Incidence of complications and the number of times the procedure was abandoned also were compared between the two imaging planes...

OBJECTIVE: The purpose of this study was to correlate upper limb volume and arterial and venous blood flow velocity in breast cancer survivors. METHODS: A cross-sectional study was conducted on 30 women with lymphedema and a mean age of 55.60 years (standard deviation = 8.12). For the assessment of upper limb volume, perimetry was performed with measures at 6 points on the limb, which were mathematically calculated as volume. The blood flow velocity of the axillary and brachial arteries and veins were assessed by Doppler ultrasound with a probe at 4 MHz...

OBJECTIVE: The purpose of this study was to assess blood flow after manual lymphatic drainage (MLD) in women who had received surgery for breast cancer and had post-axillary lymphadenectomy lymphedema. METHODS: Sixteen volunteers (mean age 64 ± 11.44 years) were divided into 2 groups. Those in group 1 received MLD without upper limb elevation, and those in group 2 received MLD with elevation of 30° of the upper limb. Blood flow velocity of the brachial vein and artery were measured using Doppler ultrasound before, immediately after, and 30 minutes after MLD, with and without 30° of upper limb elevation as defined by a random crossover design and an interval (washout) of 7 days...

Monocot stems lack the vascular cambium and instead have characteristic structures in which intercalary meristems generate internodes and veins remain separate and scattered. However, developmental processes of these unique structures have been poorly described. BELL1-like homeobox (BLH) transcription factors (TFs) are known to heterodimerize with KNOTTED1-like homeobox TFs to play crucial roles in shoot meristem maintenance, but their functions are elusive in monocots. We found that maize (Zea mays) BLH12 and BLH14 have redundant but important roles in stem development...

BACKGROUND: Due to the high incidence of thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolus [PE]) after injury, many trauma centers perform lower extremity surveillance duplex ultrasounds. We hypothesize that trauma patients are at a higher risk of upper extremity DVTs (UEDVTs) than lower extremity DVTs (LEDVTs), and therefore, all extremities should be evaluated. MATERIALS AND METHODS: A retrospective chart and trauma registry review of Intensive Care Unit trauma patients with upper and LEDVTs detected on surveillance duplex ultrasound from January 2010 to December 2014 was carried out...
