Pulmonary thromboendarterectomy in the setting of a mediastinal venous malformation with a congenitally absent left subclavian vein.

Pulm Circ 2017 Mar 1;7(1):256-260. Epub 2017 Feb 1.

Vascular Malformation Center, Swedish Medical Center, Englewood, CO, USA.

Venous malformations have static venous lakes that predispose to spontaneous venous thrombosis within the malformation due to its low-flow static state. Thrombi of varying sizes can then embolize continually into the pulmonary arterial circulation, and occlude and narrow elastic pulmonary arteries causing chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary thromboendarterectomy (PTE) is potentially curative in CTEPH, but has not been previously reported in the setting of mediastinal and chest wall venous malformations. Read More

Onyx embolization of extradural spinal arteriovenous malformations with intradural venous drainage.

Neurosurgery 2012 Feb;70(2):329-33

Department of Neurologic Surgery, Mayo Clinic, Rochester, Minnesota 55905, USA.

Background: Extradural arteriovenous malformations (AVMs) are uncommon vascular malformations of the spine. They are characterized by an arteriovenous communication (localized in the paraspinal soft tissues and the epidural venous plexus) that may have retrograde intradural venous drainage. Surgical treatment of extradural AVMs can be challenging because of the common location ventral to the dural sac and the presence of arterialized venous lakes. Read More

Dermatologic lasers in the treatment of aging skin.

Acta Dermatovenerol Croat 2010 ;18(3):176-80

University Hospital Center Zagreb , Department of Dermatology and Venereology, School of Medicine, University of Zagreb, Šalata 4, Zagreb, Croatia.

Skin aging includes intrinsic aging, a universal and inevitable process attributable to the passage of the time alone; and photoaging, changes attributable to chronic sun exposure, which are neither universal nor inevitable. The major clinical features of aging skin include xerosis, laxity, wrinkles, slackness, and the occurrence of benign neoplasms such as seborrheic keratoses and cherry angiomas. Photoaging is characterized by dryness (roughness), actinic keratoses, irregular pigmentation (freckling, lentigines, guttate hypomelanosis, persistent hyperpigmentation), wrinkling, stellate pseudoscars, elastosis (fine nodularity and/or coarseness), inelasticity, telangiectasia, venous lakes, purpura (easy bruising), comedones (maladie de Favre et Racouchot) and sebaceous hyperplasia.

Sinus pericranii with unusual features: multiplicity, associated dural venous lakes and venous anomaly, and a lateral location.

Acta Neurochir (Wien) 2010 Dec 28;152(12):2197-204. Epub 2010 Sep 28.

Department of Anaesthesiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India.

Anomalous connections between an extracranial venous sac and intracranial dural sinuses through dilated diploic and emissary veins of the skull result in sinus pericranii (SP). In this study, two patients with the rare presentation of multiple, congenital SP with associated dural venous lakes and venous anomalies are described. In one patient, multiple SPs were located in the frontal, parasagittal region with an associated subcortical venous angioma; and, in the other, peritorcular and juxta-transverse-sigmoid sinus junction SP coexisted.
