BACKGROUND: Transradial intervention (TRI) may cause damage to the radial artery (RA). We have demonstrated intima-media thickening and luminal narrowing of the distal RA after TRI using intravascular ultrasound (IVUS). This study aimed to determine the predictors of intima-media thickening of RA after TRI in the same patients using serial IVUS. METHODS AND RESULTS: We enrolled 110 consecutive patients who underwent TRI. IVUS of RA was immediately performed after TRI and repeated 6 months later...

Hypothenar hammer syndrome is a rare entity secondary to ulnar artery damage in the wrist, affecting mainly those exposed to repeated hand-palm trauma. Surgery is discussed in case of severe symptoms, resistant to medical treatment, and/or when anatomical lesions with emboligenic potential are demonstrated in the radiological exams. In this case, resection of the pathological zone with revascularization by autologous vein graft is the best option. We report the case of a 60-year-old patient who had a recurrence of symptoms more than 10 years after the completion of a surgical treatment...

Risk of cardiovascular associated death in dialysis patients is the highest among all other co-morbidities. Improving the identification of patients with the highest cardiovascular risk to design an adequate treatment is, therefore, of utmost importance. There are several non-invasive cardiovascular state biomarkers based on the pulse (pressure) wave propagation properties, but their major determinants are not fully understood. In the current study we aimed to provide a framework to precisely dissect the information available in non-invasively recorded pulse wave in hemodialysis patients...

Background: The most straightforward method of ascertaining arterial PO2 , PCO2 , and other components of blood gas is to measure them directly from a blood sample. In situations in which arterial puncture cannot be achieved or may be technically difficult, the venous blood sample can be used. Methods: In a prospective analytical study, 80 patients undergoing mechanical ventilation after open-heart surgery in the intensive care unit were evaluated. Simultaneous, matched arterial and central venous blood gas samples were taken from radial artery line and central vein, respectively, when the ABG (arterial blood gases) assessment was needed...

BACKGROUND: In 1999, Royse et al. reported on the left internal mammary artery, radial artery, Y-graft technique (LIMA-RA-Y), which achieves total arterial revascularization (TAR). However, the most common coronary reconstruction remains LIMA and supplementary saphenous vein grafts (LIMA + SVG). OBJECTIVES: The goal of this study was to conduct a survival comparison of LIMA-RA-Y versus the conventional LIMA + SVG. METHODS: Of the original 464 LIMA-RA-Y patients reported (1996 to 1998), 346 were from the Royal Melbourne Hospital...

Miroslav L Djordjevic
The current management of female to male (FTM) gender confirmation surgery is based on the advances in neo phalloplasty, perioperative care and the knowledge of the female genital anatomy, as well as the changes that occur to this anatomy with preoperative hormonal changes in transgender population. Reconstruction of the neophallus is one of the most difficult elements in surgical treatment of female transsexuals. While there is a variety of available surgical techniques, their results are not equally acceptable to all patients...

Aneurysms of the distal radial artery at the level of the wrist are rare. Most reported cases are posttraumatic, either from iatrogenic arterial puncture for radial arterial access or from a penetrating injury. Other causes include infection and connective tissue disorders. Early diagnosis is important to avoid the potential complications of thrombus formation, distal digital ischemia, and rupture. Evaluation of the radial artery is typically performed using non-invasive modalities like ultrasonography, computed tomographic angiography (CTA), and magnetic resonance angiography (MRA)...

We examined cardiovascular function in 637 volunteers (19-72 years) without antihypertensive medication in never smokers (n = 365), present smokers (n = 81) and previous smokers (n = 191, median abstinence 10 years). Haemodynamics during passive head-up tilt were recorded using whole-body impedance cardiography and radial pulse wave analysis. Results were adjusted for age, sex, body mass index, LDL cholesterol and alcohol use. Systolic and diastolic blood pressure, heart rate, and pulse wave velocity were not different between the groups...

BACKGROUND: Partially thrombosed large/giant aneurysm of the anterior cerebral artery is still challenging because this complex aneurysm requires arterial revascularization in the deep operation field. Therefore, direct neck clipping is often impossible. We describe our experiences with extracranial-intracranial bypass as an insurance bypass prior to clipping of partially thrombosed anterior cerebral artery aneurysms, and discuss the microsurgical technique and strategy. CLINICAL PRESENTATION: Consecutive, single-surgeon experience with the surgical treatment of partially thrombosed anterior cerebral artery aneurysms was retrospectively reviewed...

Objectives Upper extremity arterial access is often required for endovascular procedures, especially for antegrade access to the visceral aortic branches. Radial arterial access has been shown previously to have low complication rates, and patients tolerate the procedure well and are able to recover quickly. However, transradial access remains relatively uncommon amongst vascular surgeons. Methods The radial artery was evaluated by ultrasound to evaluate for adequate caliber, and to identify any aberrant anatomy or arterial loops...

BACKGROUND: Pulse diagnosis researches acquiring pulse waves from the wrist radial artery has not yet addressed the issue of whether this information is affected by differences in the hemodynamic characteristics of pressure waves derived from different locations. This study aimed to clarify whether the blood dynamic states are identical with regard to the "three positions and nine indicators" () listed in traditional Chinese medicine (TCM). METHODS: A total of 37 participants of CAD group and 20 participants of healthy group were recruited, and pressure pulse waves were measured at 18 locations on both hands...

Surgical therapy is the gold standard in head and neck cancer treatment, whereas adjuvant radiation and chemotherapy may be indicated in advanced cases. Frequently, neck dissections, former flap anastomoses and irradiated tissue leave a neck depleted of recipient vessels. If further surgery becomes inevitable the surgeon is faced with a heavily pretreated surgical field asking for highly reliable solutions for microsurgical reconstruction. From September 2017 until October 2017, a standardised review on the literature of the databases PubMed, Cochrane Library and Web of Science was performed...

Volar radial wrist masses are common. Adventitial cysts of the radial artery are rarely reported and poorly understood. We describe a case series of adventitial cysts in association with the radial artery and detail their pathophysiology and treatment. We conducted an IRB-approved retrospective review of patients treated at our institution from 1997 to 2018. Twelve patients were identified. Presenting symptoms typically included pain and swelling over the volar radial wrist. High resolution magnetic resonance imaging (MRI) demonstrated tubular, cystic lesions within the adventitia of the radial artery with connections to the wrist joint confirmed on multiplanar imaging: (radiocarpal joint = 10; scaphotrapeziotrapezoidal joint = 1; and intercarpal joint = 1)...

We report a male fetus with a 6.8 Mb deletion on chromosome 7p22.1p22.3 at 16 weeks of gestation. The fetus presented a heart-hand syndrome with great artery malposition, bilateral radial ray deficiency, a single pelvic kidney, and growth retardation. This deletion involves a minimal deleted region for cardiac malformation and the RAC1 gene, previously described in limb anomalies in mice. This fetus is the third human case with limb defects and RAC1 deletion.

BACKGROUND This is a very interesting case of Granulomatosis with Polyangiitis (GPA) presenting with hand ischemia which rapidly evolved into dry gangrene from the involvement of digital arteries. GPA usually affects the small and medium sized blood vessels. GPA affecting muscular artery causing limb ischemia is a rare manifestation. CASE REPORT A 72 years old Caucasian female was sent to our hospital for the evaluation of left hand pain and bluish discoloration, which she noticed for few days. Physical examination was notable for bluish discoloration of left 2nd to 5th fingers, which later evolved, into dry gangrene at the tips...

BACKGROUND: In the setting of the rapid advancement of integumentary vascular knowledge, we hypothesized that the extrinsic blood supply to the major peripheral nerves of the upper extremity could be categorized into discrete neural "perforasomes". METHODS: Total limb perfusion of the arterial system was performed with gelatin-red lead oxide in cadaveric upper limbs. The perforating vessels to the radial, median and ulnar nerves were identified, confirmed with fluoroscopy and dissected...

The technology of percutaneous coronary intervention (PCI) is constantly being refined in order to overcome the shortcomings of present day technologies. Even though current generation metallic drug-eluting stents (DES) perform very well in the short-term, concerns still exist about their long-term efficacy. Late clinical complications including late stent thrombosis (ST), restenosis, and neoatherosclerosis still exist and many of these events may be attributed to either the metallic platform and/or the drug and polymer left behind in the arterial wall...
