J Plast Reconstr Aesthet Surg 2019 Jan 15. Epub 2019 Jan 15.

Department of Plastic Surgery, West Wing, John Radcliffe Hospital, Oxford University Hospitals, Oxford, OX3 9DU, United Kingdom.

Background: A comprehensive understanding of the anatomy of the vascular supply of the coracoid is needed to ensure that the coracoid remains vascularised in order to optimize bone union during any coracoid transfer procedures. It is the purpose of this study to present an anatomical overview of the blood supply of the coracoid process, describing a previously unidentified vessel that arises directly from the axillary artery and nourishes the coracoid process, permitting the coracoid to be used as a free bone flap.

Methods: An anatomical study examining the blood supply to the coracoid process of the scapula was performed in 14 shoulders from 7 fresh frozen (unembalmed) adult cadavers. Read More

Vessel-sparing Excision and Primary Anastomosis.

J Vis Exp 2019 Jan 7(143). Epub 2019 Jan 7.

Department of Urology, Ghent University Hospital.

Urethroplasty is considered to be the standard treatment for urethral strictures since it provides excellent long-term success rates. For isolated short bulbar or posterior urethral strictures, urethroplasty by excision and primary anastomosis (EPA) is recommended. As EPA only requires the excision of the narrowed segment and the surrounding spongiofibrosis, a full-thickness transection of the corpus spongiosum, as performed in the traditional transecting EPA (tEPA), is usually unnecessary.

[The topographical and anatomical characteristic of the anterior part of the external auditory passage and the tympanic cavity].

Vestn Otorinolaringol 2018;83(2):67-72

Orenburg State Medical University, Ministry of Health of the Russian Federation, Orenburg, Russia, 460000.

The objective of the present work was to overview the currently available literature data on microtopographic anatomy of the anterior portion of the middle ear and the external auditory passage. Manipulations on these structures during miringoplasty surgery appear to be the most difficult and laborious operations because this space is anatomically very narrow and curved; moreover, it contains the important intimate structures of the middle ear and is located very close to the temporomandibular joint. The knowledge of microsurgical anatomy of the anterior part of the middle ear and the external auditory passage is paramount in the context of the improvement of the professional skills of the surgeons.

Arterial stiffness, cognitive impairment and dementia: confounding factor or real risk?

J Neurochem 2018 03 27;144(5):527-548. Epub 2017 Nov 27.

Department of Pharmacology and Physiology, Faculty of Medicine, Université de Montréal, 2900, Edouard-Montpetit, Canada.

Large artery stiffness is a frequent condition that arises with ageing, and is accelerated by the presence of co-morbidities like hypertension, obesity and diabetes. Although epidemiological studies have indicated an association between arterial stiffness, cognitive impairment and dementia, the precise effects of stiff arteries on the brain remains obscure. This is because, in humans, arterial stiffness is often accompanied by other factors such as age, high blood pressure, atherosclerosis and inflammation, which could themselves damage the brain independently of stiffness.

Expert Rev Neurother 2017 08 29;17(8):801-818. Epub 2017 Jun 29.

g Department of Intensive Care , University of Maastricht, Maastricht University Medical Center , Maastricht , The Netherlands.

Introduction: The preterm born infant's ability to regulate its cerebral blood flow (CBF) is crucial in preventing secondary ischemic and hemorrhagic damage in the developing brain. The relationship between arterial blood pressure (ABP) and CBF estimates, such as regional cerebral oxygenation as measured by near-infrared spectroscopy (NIRS), is an attractive option for continuous non-invasive assessment of cerebrovascular autoregulation. Areas covered: The authors performed a literature search to provide an overview of the current literature on various current clinical practices and methods to measure cerebrovascular autoregulation in the preterm infant by NIRS.

Epidemiology, genetics, pathophysiology, and prognostic classifications of cerebral arteriovenous malformations.

Handb Clin Neurol 2017 ;143:5-13

Department of Neurological Surgery, University of Arkansas for Medical Sciences, Little Rock, AR, USA.

Arteriovenous malformations (AVMs) are vascular deformities involving fistula formation of arterial to venous structures without an intervening capillary bed. Such anomalies can prove fatal as the high arterial flow can disrupt the integrity of venous walls, thus leading to dangerous sequelae such as hemorrhage. Diagnosis of these lesions in the central nervous system can often prove challenging as intracranial AVMs represent a heterogeneous vascular pathology with various presentations and symptomatology.

Epicardial adipose tissue is a unique fat depot around the heart that shares a close anatomic proximity and vascular supply with the myocardium and coronary arteries. Its accumulation around the heart, measured using various imaging modalities, has been associated with the onset and progression of coronary artery disease in humans. Epicardial adipose tissue is also the only fat depot around the heart that is known to express uncoupling protein 1 at both mRNA and protein levels in the detectable range. Read More

MRI-based methods for quantification of the cerebral metabolic rate of oxygen.

J Cereb Blood Flow Metab 2016 07 18;36(7):1165-85. Epub 2016 Apr 18.

University of Pennsylvania Medical Center, Philadelphia, PA, USA

The brain depends almost entirely on oxidative metabolism to meet its significant energy requirements. As such, the cerebral metabolic rate of oxygen (CMRO2) represents a key measure of brain function. Quantification of CMRO2 has helped elucidate brain functional physiology and holds potential as a clinical tool for evaluating neurological disorders including stroke, brain tumors, Alzheimer's disease, and obstructive sleep apnea.

Arterial Therapies of Non-Colorectal Liver Metastases.

Viszeralmedizin 2015 Dec 1;31(6):414-22. Epub 2015 Dec 1.

Division of Nuclear Medicine, Lausanne University Hospital, Lausanne, Switzerland.

Background: The unique situation of the liver with arterial and venous blood supply and the dependency of the tumor on the arterial blood flow make this organ an ideal target for intrahepatic catheter-based therapies. Main forms of treatment are classical bland embolization (TAE) cutting the blood flow to the tumors, chemoembolization (TACE) inducing high chemotherapy concentration in tumors, and radioembolization (TARE) without embolizing effect but very high local radiation. These different forms of therapies are used in different centers with different protocols. Read More

Haemodynamic assessment in simulated operative positions before knee arthroplasty can be useful in deep vein thrombosis prediction.

Int Orthop 2015 Sep 7;39(9):1793-6. Epub 2015 Jul 7.

Heart Centre, Clinical Centre of the University of Sarajevo, Sarajebo, Bosnia and Herzegovina.

Purpose: During knee arthroplasty, the leg is placed in several forced positions, which are mainly uncomfortable for all tissue structures in the region, including the vascular structures. Veins have a weaker quality of the wall structure than arteries, so during the forced position morphological and haemodynamic consequences are expected mainly in the venous system. Conditions of safe aseptic environment for the arthroplasty are in collision with routine intra-operative analysis of local haemodynamics in real time. Read More
