BACKGROUND: During cardiac implantable electronic device (CIED) implantation procedures cardiac leads have been mostly introduced transvenously. The associated injury to the selected vessel and adjacent tissues may induce reflex vasoconstriction. PURPOSE: To assess the incidence of cephalic vein (CV) vasoconstriction during first-time CIED implantation. METHODS: Of the 146 evaluated first-time CIED implantation procedures conducted in our center in 2016, we selected those during which CV vasoconstriction was recorded...

REVIEW
Jaber Mustafa, Ilan Asher, Zev Sthoeger
Upper extremity deep vein thrombosis (UEDVT) is defined as thrombosis of the deep venous system (subclavian, axillary, brachial, ulnar, and radial veins), which drains the upper extremities. It can be caused by thoracic outlet anatomic obstruction, such as Paget-Schroetter syndrome, (primary) or by central intravenous catheters (secondary). UEDVT may be asymptomatic or present with acute severe pain and arm swelling. Clinical suspicion should be confirmed by diagnostic imaging procedures such as duplex ultrasound, computed tomography scan, or magnetic resonance imaging...

We report the case of a young female patient who presented with a right axillary artery aneurysm with neurological symptoms due to Takayasuarteritis (TA). Decompression of the aneurysm and arterial repair with an interposition vein bypass resulted in a full recovery. The case emphasises that peripheral aneurysms can occur due to TA and that there may be neurological complications.

We investigated the anatomical features of the axillary nerve and its accompanying vessels with respect to the lateral wall of the greater tuberosity, focusing on the relationship between the neurovascular bundle and the proximal humeral locking plates. Magnetic resonance images of 30 Japanese patients' shoulders were examined. Oblique sagittal images across the greater tuberosity and the neurovascular bundle, which contain the axillary nerve and posterior circumflex humeral artery and vein, were obtained. The distance between the superior aspect of the greater tuberosity and the superior and inferior borders of the neurovascular bundles was measured at the anterior, middle, and posterior edges of the greater tuberosity...

Persistent left superior vena cava (PLSVC) is an uncommon congenital anomaly. We report a case of implantation of cardiac resynchronization therapy - pacemaker (CRT-P) device in a 38-year-old lady with idiopathic dilated cardiomyopathy. After left axillary vein puncture, we faced an unexpected entry of left subclavian to PLSVC draining into the coronary sinus (CS). The target posterolateral vein which had been identified before seemed to have an acute angle at its entry into the CS. Hence, at this stage we were in a dilemma, whether to switch to the right side or to continue from the same side...

BACKGROUND: Breast cancer-related lymphedema affects more than 400,000 survivors in the United States. In 2009, lymphatic microsurgical preventive healing approach (LYMPHA) was first described as a surgical technique to prevent lymphedema by bypassing divided arm lymphatics into adjacent veins at the time of an axillary lymph node dissection. We describe the first animal model of LYMPHA. METHODS: In Yorkshire pigs, each distal hind limb lymphatic system was cannulated and injected with a different fluorophore (human serum albumin-conjugated indocyanine green or Evans Blue)...

True axillary artery aneurysms in children are rare and mostly caused by blunt trauma. Idiopathic bilateral axillary aneurysms in children are even more infrequent and evidence for optimal management is scarce. Moreover, the maximum follow-up time of interventions reported in pediatric axillary artery aneurysms was less than one year and long-term outcomes remained unknown. In this report, we presented a 6-year-old child with bilateral axillary artery aneurysms treated by saphenous vein reconstruction with a 5-year follow-up...

A micropropagation system for Bauhinia racemosa Lam. was developed involving axillary shoot proliferation and ex vitro rooting using nodal explants obtained from mature tree. MS medium with 3.0 mg l(-1) BA (6-benzyladenine) was optimum for shoot bud induction. For shoot multiplication, mother explants were transferred repeatedly on medium containing low concentration of BA (0.75 mg l(-1)). Number of shoots was increased up to two passages and decreased thereafter. Shoot multiplication was further enhanced on MS medium containing 0...

The cephalic vein arises from the radial end of the dorsal venous arch. It turns around the radial border of the forearm and passes proximally along the arm to the shoulder, where it enters the axillary vein by penetrating the clavipectoral triangle. The cephalic vein is prone to vary at the antecubital fossa, where it forms numerous anastomoses. A male cadaver fixated with a 10% formalin solution was dissected during regular anatomy lessons. It was found that the cephalic vein crossed the upper third of the arm between two fasciculi of the deltoid muscle and reached the shoulder, where it passed above the acromion and crossed the posterior border of the clavicle in order to join the external jugular vein...

Prosthetic arteriovenous grafts (AVGs) conventionally used for hemodialysis are associated with inferior primary patency rates and increased risk of infection compared with autogenous vein grafts. We tissue-engineered an AVG grown from neonatal human dermal fibroblasts entrapped in bovine fibrin gel that is then decellularized. This graft is both "off-the-shelf" (nonliving) and completely biological. Grafts that are 6 mm in diameter and about 15 cm in length were evaluated in a baboon model of hemodialysis access in an axillary-cephalic or axillary-brachial upper arm AVG construction procedure...
