This study aimed to evaluate the role of gender in types and frequency of coronary artery aneurysm and ectasia.We assessed retrospectively the angiography records of 6100 patients. At first, we mainly reviewed angiographic movies for the presence of coronary ectasia and/or aneurysm. Consequently, based on the number of the coronary artery involvement, the coronary ectasia and aneurysm were grad...
PURPOSE To analyze the risk factors associated with a series of ectasia cases following photorefractive keratectomy (PRK) and all published cases. METHODS In a retrospective study on post-PRK ectasia patients, 9 eyes of 7 patients were included, in addition to 20 eyes of 13 patients from the literature. Risk of post-PRK ectasia was calculated using the ectasia risk score system (ERSS) for las...
PURPOSE To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection. METHODS Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204...
Corneal ectasia is a serious complication of laser in situ keratomileusis (LASIK). We report the case of a 29-year-old man who underwent LASIK in both eyes and in whom corneal ectasia developed in the left eye 3 years after surgery. He was treated sequentially with intraocular pressure-lowering medication, intrastromal corneal ring segment (ICRS) implants, and collagen cross-linking. Vision imp...
The incidence of male duct ectasia (periductal mastitis) is extremely rare, only eight cases having been reported. The underlying cause (as in females) is uncertain. Two cases in HIV positive males of recurrent unilateral nipple lesions are reported with histology consistent with duct ectasia. At presentation neither patient had an AIDS defining illness. An impaired immunity secondary to HIV in...
frequent cause of lower intestinal bleed− ing in the elderly. Recent advances in co− lonoscopy have discovered colonic vascu− lar ectasia with increasing frequency. Co− lonic vascular ectasia often presents as multiple reddish, slightly elevated, muco− sal lesions. It may be treated at colonos− copy with laser photocoagulation, heat probe, electrocoagulation, and argon plasma coagulation [1 ± 4...
collagen fibrils, extracellular empty spaces(likelyclefts formedfromlipid removalduringprocessing), andpersistentlyactivatedkeratocytesaresimilar to these animal findings. The extracellular lipid collections, which likelycorrespondtothecrystallinedeposits seen clinically, probably arise fromchronicmechanical irritation to keratocytes that continually strive to heal the stromal wound. The breaks...
BACKGROUND AND PURPOSE Intracranial artery dolichoectasia (IADE) and coronary artery ectasia have been associated with stroke and myocardial infarction, respectively. Only rarely have cases of coexisting IADE and coronary artery ectasia been reported. We investigated this association in a large consecutive autopsy series. METHODS Sixteen stroke patients with IADE were identified among 381 str...
PURPOSE Four cases of corneal ectasia after small-incision lenticule extraction (SMILE) have been reported. In this review, we provide an overview of the published literature on corneal ectasia after SMILE and risk factors associated with this complication. METHODS Case reports were identified by a search of seven electronic databases for pertinent heading terms between 2011 and July 2017. We...
