This study compares procedural complications and clinical outcomes between subintimal crossing versus intraluminal crossing during endovascular treatment of infrainguinal peripheral artery chronic total occlusions (CTO). We identified 1335 CTO interventions in 1001 patients from the multicenter Excellence in Peripheral Artery Disease (XLPAD) registry from January 2005 to October 2015. Outcomes included 30-day and 12-month all-cause death, non-fatal myocardial infarction or stroke, peripheral artery stent, or vessel, thrombosis (ST), need for any target limb endovascular or surgical revascularization, target limb major amputation and procedural complications. A subintimal crossing technique was necessary in 388 lesions (27% overall in 1335 lesions; 34% ( n=351) in 1023 femoropopliteal lesions, and 12% ( n=37) in 312 infrapopliteal lesions, p<0.01) with a lower procedural ( p<0.01) and technical ( p<0.01) success than the intraluminal in both femoropopliteal and infrapopliteal interventions. There were no significant differences in procedural complications, major adverse cardiac events, or clinically driven target limb revascularization at 1 year between the two groups, except a higher residual dissection rate in the subintimal crossing group than the intraluminal group in femoropopliteal target vessels ( p = 0.04).
Mesenchymal origin of primary thyroid angiosarcomas (TAS) is extremely rare and comprises less than 1% of primary thyroid cancer worldwide. While TAS are most commonly occurring in the Alpine region, there are multiple reported cases of TAS in non-Alpine regions. Diagnosis of TAS is commonly made after thyroidectomy as cytologic diagnosis can be challenging due to paucity of cells, presence of necrosis and unawareness of the disease due to rarity. We report a case of primary TAS diagnosed by cytology in a 56-year-old man who presented with a sudden onset of left neck pain, swelling and haemoptysis. He was later noted to have suspicious nodules on both lobes of thyroid on ultrasound. Fine needle aspiration of thyroid nodules showed malignant epithelioid cells. The diagnosis of TAS was made based on positive endothelial markers such as thrombomodulin and CD31, with many pertinent negatives, including negative cytokeratins,thyroid transcription factor (TTF1), thyroglobulin, calcitonin and carcinoembryonic antigen (CEA).
The app may be of great benefit to patients with aphasia and other communication disorders. Implications for Rehabilitation We have made a phonology-free mobile communication app. This app may facilitate communication for patients with aphasia and other communication disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
