Authors:
Brent A Vogt

Handb Clin Neurol 2019 ;166:3-21

Cingulum Neurosciences Institute, Manlius, NY, United States; Department of Anatomy and Neurobiology, Boston University School of Medicine, Boston, MA, United States.

A brief review of the history of key observations of cingulate organization, particularly in the limbic system framework, is presented from 1907 to the present. The reasons why it has not played a significant role in neurology reflect the fact that its arterial supply is complex and no cingulate syndrome has been identified. A flat map of its eight subregions and areas is presented as a basis for many subsequent chapters in this volume. Read More

Current management strategies for visceral artery aneurysms: an overview.

Surg Today 2020 Jan 16;50(1):38-49. Epub 2019 Oct 16.

Department of Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo, 160-8582, Japan.

Visceral artery aneurysms (VAAs) are rare and affect the celiac artery, superior mesenteric artery, and inferior mesenteric artery, and their branches. The natural history of VAAs is not well understood as they are often asymptomatic and found incidentally; however, they carry a risk of rupture that can result in death from hemorrhage in the peritoneal cavity, retroperitoneal space, or gastrointestinal tract. Recent advances in imaging technology and its availability allow us to diagnose all types of VAA. Read More

Limb ischemia in peripheral veno-arterial extracorporeal membrane oxygenation: a narrative review of incidence, prevention, monitoring, and treatment.

Crit Care 2019 Jul 30;23(1):266. Epub 2019 Jul 30.

Department of Cardio-Thoracic Surgery, Heart and Vascular Centre, Maastricht University Medical Centre (MUMC), Cardiovascular Research Institute (CARIM), Maastricht University, Maastricht, The Netherlands.

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is an increasingly adopted life-saving mechanical circulatory support for a number of potentially reversible or treatable cardiac diseases. It is also started as a bridge-to-transplantation/ventricular assist device in the case of unrecoverable cardiac or cardio-respiratory illness. In recent years, principally for non-post-cardiotomy shock, peripheral cannulation using the femoral vessels has been the approach of choice because it does not need the chest opening, can be quickly established, can be applied percutaneously, and is less likely to cause bleeding and infections than central cannulation.

Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts. Electronic address:

Since the term "lacune" was adopted in the 1800s to describe infarctions from cerebral small vessels, their underlying pathophysiological basis remained obscure until the 1960s when Charles Miller Fisher performed several autopsy studies of stroke patients. He observed that the vessels displayed segmental arteriolar disorganization that was associated with vessel enlargement, hemorrhage, and fibrinoid deposition. He coined the term "lipohyalinosis" to describe the microvascular mechanism that engenders small subcortical infarcts in the absence of a compelling embolic source. Read More

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.

Overview and Critical Appraisal of Arterial Spin Labelling Technique in Brain Perfusion Imaging.

Contrast Media Mol Imaging 2018 8;2018:5360375. Epub 2018 May 8.

Department of Brain Repair & Rehabilitation, UCL Institute of Neurology, London, UK.

Arterial spin labelling (ASL) allows absolute quantification of CBF via a diffusible intrinsic tracer (magnetically labelled blood water) that disperses from the vascular system into neighbouring tissue. Thus, it can provide absolute CBF quantification, which eliminates the need for the contrast agent, and can be performed repeatedly. This review will focus on the common ASL acquisition techniques (continuous, pulsed, and pseudocontinuous ASL) and how ASL image quality might be affected by intrinsic factors that may bias the CBF measurements.

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.

Charlie Norwood VA Medical Center, Augusta, Georgia, USA.

Metabolic diseases including obesity, insulin resistance, and diabetes have profound effects on cerebral circulation. These diseases not only affect the architecture of cerebral blood arteries causing adverse remodeling, pathological neovascularization, and vasoregression but also alter the physiology of blood vessels resulting in compromised myogenic reactivity, neurovascular uncoupling, and endothelial dysfunction. Coupled with the disruption of blood brain barrier (BBB) integrity, changes in blood flow and microbleeds into the brain rapidly occur. Read More

1st Department of Cardiology, 'Hippokration' Hospital, University of Athens, Medical School, Athens, Greece. Electronic address:

Peripheral artery disease (PAD) is a vascular problem of diffuse atherosclerosis and is a major cause of cardiovascular morbidity and mortality. Many studies have tried to gain insight into the molecular mechanisms involved in PAD. Lately, highly stable circulating small noncoding RNAs, microRNAs (miRNAs), seem to have disease-specific expression. Read More

Interventions for lower extremity peripheral artery disease.

Nat Rev Cardiol 2018 06;15(6):332-350

Division of Vascular and Endovascular Surgery, University of California, San Francisco, CA, USA.

Peripheral artery disease (PAD) of the lower extremities is a common manifestation of atherosclerosis that is increasing in global prevalence and in the associated public health costs. Ageing of the general population, combined with the pandemics of diabetes mellitus, metabolic syndrome, and tobacco use, is a major underlying factor. A broad range of care providers are involved in the management of patients with PAD, and all health-care professionals require familiarity with the risk factors, diagnosis, and treatment options for this common disease.

Neuroimage 2019 02 29;187:145-153. Epub 2018 Mar 29.

Cardiff University Brain Research Imaging Centre, School of Psychology, Cardiff University, Maindy Road, CF24 4HQ, Cardiff, UK. Electronic address:

Functional magnetic resonance imaging (fMRI) is an essential workhorse of modern neuroscience, providing valuable insight into the functional organisation of the brain. The physiological mechanisms underlying the blood oxygenation level dependent (BOLD) effect are complex and preclude a straightforward interpretation of the signal. However, by employing appropriate calibration of the BOLD signal, quantitative measurements can be made of important physiological parameters including the absolute rate of cerebral metabolic oxygen consumption or oxygen metabolism (CMRO) and oxygen extraction (OEF).

MRA of the skin: mapping for advanced breast reconstructive surgery.

Clin Radiol 2019 01 2;74(1):13-28. Epub 2018 Mar 2.

Radiology, New York-Presbyterian Hospital, Columbia University, NY, USA; Radiology, Weill Cornell Medical Center, NY, USA.

Autologous breast reconstruction using muscle-sparing free flaps are becoming increasingly popular, although microvascular free flap reconstruction has been utilised for autologous breast reconstructions for >20 years. This innovative microsurgical technique involves meticulous dissection of artery-vein bundle (perforators) responsible for perfusion of the subcutaneous fat and skin of the flap; however, due to unpredictable anatomical variations, preoperative imaging of the donor site to select appropriate perforators has become routine. Preoperative imaging also reduces operating time and enhances the surgeon's confidence in choosing the appropriate donor site for harvesting flaps. Read More

Acute mesenteric ischemia: A critical role for the radiologist.

Diagn Interv Imaging 2018 Mar 9;99(3):123-134. Epub 2018 Feb 9.

Department of Radiology, University Hospitals Paris Nord Val-de-Seine, Beaujon, 92110 Clichy, Hauts-de-Seine, France; University Paris Diderot, Sorbonne Paris Cité, 75018 Paris, France; Inserm U1149, centre de recherche biomédicale Bichat-Beaujon, CRB3, 92110 Paris, France. Electronic address:

Acute mesenteric ischemia is defined as an inadequate blood supply to the gastrointestinal tract resulting in ischemic and inflammatory injury that may progress to necrosis of the bowel wall. Prognosis is poor with a mortality rate greater than 95% without treatment, dropping to around 70% when surgical treatment is performed. Contrast-enhanced computed tomography (CT) has become the cornerstone of the diagnosis by showing features of vascular disorders (occlusion and/or insufficient blood supply) and features of intestinal ischemic injury.

Electroencephalography and Brain Oxygenation Monitoring in the Perioperative Period.

Anesth Analg 2019 02;128(2):265-277

Department of Anesthesiology and Intensive Care Medicine, University of Lübeck, Lübeck, Germany.

Maintaining brain function and integrity is a pivotal part of anesthesiological practice. The present overview aims to describe the current role of the 2 most frequently used monitoring methods for evaluation brain function in the perioperative period, ie, electroencephalography (EEG) and brain oxygenation monitoring. Available evidence suggests that EEG-derived parameters give additional information about depth of anesthesia for optimizing anesthetic titration. Read More

[Guideline recommendations and quality indicators for invasive treatment of peripheral arterial disease in Germany : The IDOMENEO study for quality improvement and research in vascular medicine].

Bundesgesundheitsblatt Gesundheitsforschung Gesundheitsschutz 2018 Feb;61(2):218-223

Universitäres Herzzentrum Hamburg, Klinik und Poliklinik für Gefäßmedizin, Universitätsklinikum Hamburg-Eppendorf, Martinistraße 52, 20246, Hamburg, Deutschland.

Due to the paucity of independent trials, practical guidelines for the diagnosis and treatment of peripheral arterial disease (PAD) contain several recommendations developed by expert consensus. Furthermore, there is a lack of commonly defined quality indicators and valid data on real world treatment. Therefore, it remains challenging to scrutinize if treatment reality is conforming to guideline recommendations. Read More
