TGFβ (Transforming Growth Factor-Beta)-Activated Kinase 1 Regulates Arteriovenous Fistula Maturation.

Arterioscler Thromb Vasc Biol 2020 May 28:ATVBAHA119313848. Epub 2020 May 28.

Department of Surgery, Yale University School of Medicine, New Haven, CT (H.H., S.-R.L., H.B., J.G., T.H., T.I., X.G., T.W., K.W., S.L., S.O., B.Y., A.D.).

Objective: Arteriovenous fistulae (AVF) are the optimal conduit for hemodialysis access but have high rates of primary maturation failure. Successful AVF maturation requires deposition of ECM (extracellular matrix) including collagen and fibronectin, as well as orderly temporal regulation of ECM components. TAK1 (TGFβ [transforming growth factor-beta]-activated kinase 1) is a mediator of noncanonical TGFβ signaling and plays crucial roles in regulation of ECM production and deposition; therefore, we hypothesized that TAK1 regulates wall thickening during AVF maturation by alteration of expression of components of the ECM.

Efficacy of intraarterial superselective indocyanine green videoangiography in cerebral arteriovenous malformation surgery in a hybrid operating room.

J Neurosurg 2020 May 22:1-9. Epub 2020 May 22.

1Department of Neurosurgery, Tokushima University Hospital, Tokushima.

Objective: Although intravenous indocyanine green (ICG) videoangiography has been reported to be useful when applied to cerebral arteriovenous malformation (AVM) surgery, the ICG that remains after the procedure makes it difficult to understand the anatomy, to evaluate nidus blood flow changes, and to repeat ICG videoangiography within a short time. Intraarterial ICG videoangiography has emerged as a way to overcome these limitations. The current study presents the results of intraarterial ICG videoangiography undertaken in patients with cerebral AVMs. Read More

Successful double-catheter coil embolization of an iatrogenic subclavian artery-internal jugular vein fistula after minimally invasive cardiac surgery.

Ann Vasc Surg 2020 May 15. Epub 2020 May 15.

Department of Neurosurgery, Kobe University Graduate School of Medicine, Kobe, Japan.

It is essential to establish cardiopulmonary bypass by percutaneous insertion of a large-bore catheter via both the femoral vein and internal jugular vein (IJV) for minimally invasive cardiac surgery (MICS). Complications associated with IJV catheterization during MICS have been reported in the literature; however, vascular injury of the subclavian artery (SCA) is rare. We herein present a rare case in which an iatrogenic arteriovenous fistula (AVF) between the right SCA and IJV after MICS was successfully treated by endovascular coil embolization. Read More

Neuroangiography: Review of Anatomy, Periprocedural Management, Technique, and Tips.

Semin Intervent Radiol 2020 Jun 14;37(2):166-174. Epub 2020 May 14.

Department of Neurosurgery, University of Colorado School of Medicine, Aurora, Colorado.

Neuroangiography (NA) is a minimally invasive procedure used to diagnose patients with neurovascular diseases. Noninvasive imaging has improved dramatically in recent years and is utilized more frequently; however, further evaluation with NA is still required in certain cases. NA indications include intracranial (cerebral aneurysms, arteriovenous malformations, dural arteriovenous fistula, cerebral vasculitis, cerebral vasospasm, ischemic stroke, nontraumatic subarachnoid hemorrhage, intracerebral hemorrhage, Moyamoya, vein of Galen malformation, intracranial tumors, and pseudotumor cerebri) and extracranial (internal and common carotid artery stenosis, vertebral artery stenosis, carotid artery blowout, vertebral artery blowout, epistaxis, oropharyngeal bleeding, and carotid body tumor) pathologies which can help with diagnosis and potential subsequent endovascular treatment.

Percutaneous Ultrasound-Guided Access to the Superior Ophthalmic Vein for Embolization of a Cavernous Sinus Dural Arteriovenous Fistula.

Cureus 2020 May 11;12(5):e8053. Epub 2020 May 11.

Oculo-Facial Plastic and Cosmetic Surgery, Vietnam National Eye Hospital, Hanoi, VNM.

The treatment of symptomatic cavernous sinus dural arteriovenous fistula, an unusually occluded cavernous sinus, is by a transvenous approach through the inferior petrosal sinus and superior ophthalmic vein. If these two modes of conventional transvenous access are not possible, surgical exposure and/or direct puncture access to the superior ophthalmic vein or cavernous sinus have been previously described. In a patient with progressive ophthalmological problems, the goal of treatment is to not only cure the ophthalmic symptoms but also to conserve or improve visual acuity, so treatment is needed as soon as possible.

Updates in the management of cranial dural arteriovenous fistula.

Stroke Vasc Neurol 2020 21;5(1):50-58. Epub 2019 Nov 21.

Neurosurgery, Ronald Reagan UCLA Medical Center, Los Angeles, California, USA.

Dural arteriovenous fistula (dAVF) accounts for approximately 10% of all intracranial vascular malformations. While they can be benign lesions, the presence of retrograde venous drainage and cortical venous reflux makes the natural course of these lesions aggressive high risk of haemorrhage, neurological injury and mortality. Endovascular treatment is often the first line of treatment for dAVF. Read More

Endovascular treatment of the cavernous sinus dural arteriovenous fistula: current status and considerations.

Int J Med Sci 2020 1;17(8):1121-1130. Epub 2020 May 1.

Department of Neurosurgery, The First Hospital of Jilin University, Changchun, 130021, China.

A cavernous sinus dural arteriovenous fistula (CS-DAVF) is an abnormal arteriovenous communication involving the dura mater within or near the CS wall. The dural arteries from the internal carotid artery and external carotid artery supply the CS-DAVF, and the superior ophthalmic vein (SOV) and inferior petrous sinus (IPS) are frequent venous drainers. In CS-DAVF cases, high-risk lesions require treatment. Read More

[Natriuretic peptides in dialysis: From theory to clinical practice].

Nephrol Ther 2020 May 11. Epub 2020 May 11.

Service de néphrologie et dialyse, NephroCare Tassin-Charcot, 7, avenue du Maréchal-Foch, 69110 Sainte-Foy-les-Lyon, France.

Cardiologists and emergency-wards physicians are used to check natriuretic peptides serum level, mainly B-type natriuretic peptide and N-terminal pro-Brain natriuretic peptide for acute cardiac failure diagnosis. Due to their accumulation in chronic kidney disease and their elimination by dialysis, natriuretic peptides sampling remains debatable in chronic kidney disease patients. In dialysis patients, high natriuretic peptides values are associated with mortality, left ventricular hypertrophy and cardiac failure. Read More
