Proximal iliac limb extension and embolization: a new technique of complete endovascular management of an unfavorably sited type III endoleak.

Diagn Interv Radiol 2021 Jul;27(4):570-572

Barking Havering and Redbridge University Hospitals NHS Trust, Queen's Hospital, Rom Valley Way, Romford, London, United Kingdom.

Type III endoleak is an uncommon but life-threatening complication of endovascular aortic repair, and such leaks at certain sites can be challenging to treat through an endovascular route. A 77-year-old man presented with severe abdominal pain and was found to have an abdominal aortic aneurysm with contained rupture due to an unfavorably cited type IIIb endoleak. He was successfully treated with an endovascular approach using bilateral iliac limb proximal extension combined with embolization of endoleak sac, endoleak site and the feeding recess, preserving flow through both the iliac limbs obviating the need for an additional femorofemoral bypass.

Incidence of major complications from embolo-sclerotherapy of head and neck vascular malformations in a single specialist centre.

Vascular 2021 Jul 26:17085381211035279. Epub 2021 Jul 26.

Department of Vascular Surgery, 4965Royal Free London NHS Foundation Trust, London, UK.

Objective: Current data on the nature and rate of major complications for embolo-sclerotherapy (EST) of vascular malformations are scarce. However, even fewer studies focus on vascular malformations specific to the head and neck, which confer an increased specific risk of airway compromise, neurologic and ophthalmologic injury. More understanding is required surrounding the type and incidence of complications to improve treatment planning and informed consent. Read More

Spontaneous intracranial hypotension: diagnostic and therapeutic workup.

Neuroradiology 2021 Jul 23. Epub 2021 Jul 23.

Department of Neuroradiology, Medical Center, University of Freiburg, Breisacher Str. 64 , 79106, Freiburg, Germany.

Spontaneous intracranial hypotension (SIH) is an orthostatic headache syndrome with typical MRI findings among which engorgement of the venous sinuses, pachymeningeal enhancement, and effacement of the suprasellar cistern have the highest diagnostic sensitivity. SIH is in almost all cases caused by spinal CSF leaks. Spinal MRI scans showing so-called spinal longitudinal extradural fluid (SLEC) are suggestive of ventral dural tears (type 1 leak) which are located with prone dynamic (digital subtraction) myelography.

Vasc Endovascular Surg 2021 Jul 22:15385744211028738. Epub 2021 Jul 22.

Department of Diagnostic Radiology and Radiation Oncology, Chiba University Graduate School of Medicine, Inohana, Chuo-ku, Chiba City, Chiba, Japan.

A 61-year-old man presented with retroperitoneal hemorrhage caused by an aneurysm rupture of the pancreaticoduodenal arcade (PDA), and acute celiac artery dissection distal to celiac axis stenosis. Owing to the gradual growth of the false lumen, we planned to deploy a stent to the celiac artery dissection and embolize the PDA aneurysm. Prior to stent placement, we assessed the acute celiac artery dissection distal to the stenosis using four-dimensional computed tomography (CT) angiography through expiration/inspiration/expiration cycle.

The fate of the left subclavian artery in TEVAR for aortic arch pathology.

J Card Surg 2021 Jul 26. Epub 2021 Jul 26.

Department of Vascular Surgery, University Hospital of Wales, Heath Park, Cardiff, UK.

Background And Aim Of Study: The origin of the vertebral artery (VA) from the left subclavian (LSA) is variable and must be considered when proximal ligation or embolization is performed post thoracic endovascular aortic repair (TEVAR) and extra-anatomical bypass (EAB). A retrospective study was conducted to understand the patency of the LSA and VAs after TEVAR and the relationship of the EAB to the LSA.

Gelfoam embolization for distal, medium vessel injury during mechanical thrombectomy in acute stroke: A case report.

World J Clin Cases 2021 Jul;9(20):5668-5674

Department of Radiology, Chungbuk National University Hospital, Cheongju 28644, South Korea.

Background: Arterial perforation has inevitably increased as endovascular treatments have become more common for intracranial large vessel occlusions, and even distal, medium vessel occlusions. A distal, medium vessel has a tortuous course and thinner wall compared to large arteries, making it more susceptible to damage. Here, we review the treatment strategies for arterial perforation during mechanical thrombectomy, and we report the case of a patient treated with gelfoam embolization. Read More

J Neurol Surg B Skull Base 2021 Jul 15;82(Suppl 3):e278-e284. Epub 2020 May 15.

Advocate Aurora Health, Cerebrovascular Neurosurgery and Comprehensive Stroke Center, Chicago, Illinois, United States.

Multiple strokes due to pulmonary arteriovenous malformation.

Radiol Case Rep 2021 Sep 1;16(9):2362-2365. Epub 2021 Jul 1.

Department of Cardiology, Maimonides Medical Center, 4802 10th Ave, Brooklyn, NY, USA.

We present a case of recurrent strokes in a patient with absent left internal carotid artery (ICA) and pulmonary arteriovenous malformation. Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between pulmonary artery and pulmonary vein, cause extracardiac right to left shunting of blood and are known to significantly increase the risk of stroke primarily due to paradoxical embolization. They are often hereditary and are commonly associated with hereditary hemorrhagic telangiectasias (HHT). Read More

Treatment of Intracranial Aneurysms Using the New Silk Vista Flow Diverter: Safety Outcomes at Short-Term Follow-Up.

Front Neurol 2021 9;12:713389. Epub 2021 Jul 9.

Neuroradiology Department, Hospital Universitario de Cruces, Barakaldo, Spain.

Flow diverters are widely used as the first endovascular treatment option for complex brain aneurysms due to their high percentage of occlusion and low morbi-mortality. The Silk Vista device is a new generation of flow diverters designed to facilitate full visibility, improve apposition to the vessel wall, and enhance navigability. Indeed, its greatest advantage is that it enables the easier navigation of stents between 3. Read More

Embolotherapy in Bronchial Hemorrhage.

Thorac Surg Clin 2021 Aug 10;31(3):323-332. Epub 2021 Jun 10.

Division of Vascular and Interventional Radiology, Department of Medical Imaging, University of Ottawa, The Ottawa Hospital, 501 Smyth Road, Ottawa, Ontario K1H8L6, Canada.

Hemoptysis, defined as bleeding into the tracheobronchial tree, is a serious symptom that can cause asphyxiation if inadequately treated. Massive hemoptysis carries a very high mortality risk, and therefore, a prompt multidisciplinary approach to hemoptysis is highly encouraged. Bronchial artery embolization has evolved as the mainstay of treatment in control of hemoptysis. Read More
