Orbital Infarction Syndrome Following Mechanical Thrombectomy Secondary to Embolization in New Territory.

World Neurosurg 2018 Sep 20;117:326-329. Epub 2018 Jun 20.

Joint Department of Medical Imaging, Toronto Western Hospital, University of Toronto, Toronto, Ontario, Canada.

Background: Orbital infarction syndrome (OIS) is a rare entity defined as ischemia of all intraorbital and intraoccular structures including the optic nerve, extraocular muscles, and orbital fat. This entity is rare due to rich anastomotic orbital vascularization from both the internal carotid artery and external carotid artery. We report a case of a patient who suffered emboli to previously nonaffected territories to the ophthalmic artery and external carotid artery, which resulted in orbital infarction syndrome, and describe techniques to avoid such complications.

The Face – A Vascular Perspective. A literature review

Swiss Dent J 2018 May;128(5):382-392

Department of Anatomy, Biochemistry and Physiology, John A. Burns School of Medi­cine, University of Hawai’i, Honolulu, USA

Vascular supply is key for maintenance of healthy tissue conditions but also with regard to healing following trauma or therapeutic interventions. The face is probably the most exposed part of the body and any changes of vascularity are readily visible (skin blanching, ecchymosis, hematoma, edema). With regard to the arterial supply, all vessels reaching the facial skin originate from the bilateral common carotid arteries. Read More

An Applied Anatomical Study of the Ethmoidal Arteries: Computed Tomographic and Direct Measurements in Human Cadavers.

J Craniofac Surg 2018 Jan;29(1):212-216

Department of Cellular and Molecular Medicine, University of Copenhagen.

Computed tomography (CT) images have been used in very few studies on distances to the ethmoidal arteries in the orbit. Most other studies have included direct measurements on cadavers and frequently quote the 24-12-6 mm rule to describe distances from the anterior lacrimal crest to the anterior and posterior ethmoidal foramina (AEF and PEF), optic canal (OC), respectively. However, the large interindividual variation of distances renders absolute values less applicable in a clinical setting. Read More

Combined approach to management of periocular arteriovenous malformation by interventional radiology and surgical excision.

Indian J Ophthalmol 2018 01;66(1):151-154

Department of Interventional Radiology, Apollo Specialty Hospitals, Chennai, Tamil Nadu, India.

Periorbital arteriovenous malformations (AVMs) are congenital lesions that may cause significant morbidity such as amblyopia, cosmetic disfigurement, or chronic pain. Due to the rarity of these lesions, they are frequently misdiagnosed and treated inappropriately. We managed a 6-year-old girl with preseptal AVM by endovascular embolization followed by complete surgical excision after 2 days. Read More

*Department of Ophthalmology, University of Ottawa Eye Institute, Ottawa, Ontario, Canada; and †Centro Oftalmologico y Oculoplastico de Madrid, Hospital Universitario Madrid Norte Sanchinarro, Hospital Universitario de Fuenlabrada, Madrid, Spain.

The gracillimus orbitis muscle is an anomalous, accessory, or supernumerary extraocular muscle that, although is rarely seen clinically in the human orbit, has been identified in 5% to 14% of dissected cadaver orbits. It arises from the medial surface of the levator near its origin and runs forward between the levator and superior oblique muscles resembling one of the other extraocular muscles. More anteriorly, it becomes thinner, less well defined, and mostly fibrous. Read More

Vascular patterns in the heads of crocodilians: blood vessels and sites of thermal exchange.

J Anat 2016 12 28;229(6):800-824. Epub 2016 Sep 28.

Department of Biomedical Sciences, Ohio University Heritage College of Osteopathic Medicine, Athens, OH, USA.

Extant crocodilians are a highly apomorphic archosaur clade that is ectothermic, yet often achieve large body sizes that can be subject to higher heat loads. Therefore, the anatomical and physiological roles that blood vessels play in crocodilian thermoregulation need further investigation to better understand how crocodilians establish and maintain cephalic temperatures and regulate neurosensory tissue temperatures during basking and normal activities. The cephalic vascular anatomy of extant crocodilians, particularly American alligator (Alligator mississippiensis) was investigated using a differential-contrast, dual-vascular injection technique and high resolution X-ray micro-computed tomography (μCT).

Artery of the Superior Orbital Fissure: An Undescribed Branch from the Pterygopalatine Segment of the Maxillary Artery to the Orbital Apex Connecting with the Anteromedial Branch of the Inferolateral Trunk.

AJNR Am J Neuroradiol 2015 Sep 23;36(9):1741-7. Epub 2015 Jul 23.

From the Department of Radiology, Oita University Faculty of Medicine, Oita, Japan.

Background And Purpose: Some branches of the internal maxillary artery have anastomoses with the inferolateral trunk that are important as intracranial-extracranial collateral pathways and as dangerous anastomoses for transarterial embolization of these branches. We present here an undescribed branch potentially anastomosing with the anteromedial branch of the inferolateral trunk, which is provisionally named the artery of the superior orbital fissure, defined as an arterial branch from the pterygopalatine segment of the maxillary artery to the orbital apex at the superior orbital fissure.

Materials And Methods: Two neuroradiologists reviewed 3D and MPR images of the external and/or common carotid artery with particular interest paid to the artery of the superior orbital fissure in 54 patients who underwent 3D angiography with a field of view covering the pterygopalatine fossa and the cavernous sinus.

Combined transcervical and orbitozygomatic approach for the removal of a nasopharyngeal adenocarcinoma.

Auris Nasus Larynx 2016 Apr 9;43(2):192-6. Epub 2015 Jul 9.

Department of Otorhinolaryngology, Graduate School of Medical Science, Kyushu University, 3-1-1 Maidashi, Higashiku, Fukuoka 812-8582, Japan.

Objective: In some cases, the exposure and safeguarding of the internal carotid artery (ICA) are not easy by the maxillary swing approach that is used as a mainstay for the removal of nasopharyngeal tumors. To address this issue, we have developed a new combined transcervical and orbitozygomatic approach.

Methods: A nasopharyngeal adenocarcinoma arose in a 52-year-old patient and occupied the right middle skull base extending to the ICA. Read More

Orbit 2015 4;34(4):212-5. Epub 2015 Jun 4.

Department of Ophthalmology, Harvard Medical School , Boston, Massachusetts , USA .

The orbital branch of the infraorbital artery, a key vascular structure that is not universally noted in orbital textbooks and atlases, is clinically significant, since injury to it can result in perioperative hemorrhage. We conducted a cadaver dissection to document its presence, measure its location, and evaluate it histopathologically. It was present in 8 of 9 orbits and was a mean distance of 16. Read More
