Altoijry A, Lindsay T, Johnston K, Mamdani M, Al-Omran M
J Int Med Res . 2021 Jan; 49(1):300060520987728. PMID: 33512260
Objective: Trauma-related vascular injuries are major contributors to morbidity and mortality worldwide. We conducted a retrospective, population-based, cross-sectional study to examine temporal trends and factors associated with traumatic vascular injury-related...

Altoijry A, Al-Omran M, Johnston K, Mamdani M, Lindsay T
CMAJ Open . 2016 Jul; 4(2):E309-15. PMID: 27398379
Background: Vascular injuries add substantial complexity to trauma care, yet Canadian epidemiologic data on such injuries are not readily available. We conducted a retrospective cross-sectional study to examine temporal trends...

Kotowycz M, Johnston K, Ivanov J, Asif N, Almoghairi A, Choudhury A, et al.
Can J Cardiol . 2014 Jan; 30(2):211-6. PMID: 24461923
Background: Radial artery occlusion occurs after transradial cardiac catheterization or percutaneous coronary intervention. Although use of a sheath larger than the artery is a risk factor for radial artery occlusion,...

Altoijry A, Al-Omran M, Lindsay T, Johnston K, Melo M, Mamdani M
Can J Surg . 2013 Nov; 56(6):405-8. PMID: 24284148
Background: The use of administrative databases in vascular injury research has been increasing, but the validity of the diagnosis codes used in this research is uncertain. We assessed the positive...

Warriner R, Johnston K, Cobbold R
Physiol Meas . 2008 Feb; 29(2):157-79. PMID: 18256449
The existing computational model studies of pulsatile blood flow in arteries have assumed either rigid wall characteristics or elastic arterial wall behavior with wall movement limited to the radial direction....

Harlal A, Ojha M, Johnston K
J Vasc Interv Radiol . 2007 Feb; 18(1 Pt 1):103-15. PMID: 17296710
Purpose: Three inferior vena cava (IVC) filters of different designs were studied to identify the potential links between published clinical results for thrombosis and recurrent pulmonary embolism (PE) rates and...

Lui E, Steinman A, Cobbold R, Johnston K
J Vasc Surg . 2005 Nov; 42(5):972-9. PMID: 16275456
Objective: The study was conducted to assess the error and variability that results from human factors in Doppler peak velocity measurement. The positioning of the Doppler sample volume in the...

Steinman A, Yu A, Johnston K, Cobbold R
Ultrasound Med Biol . 2005 Aug; 31(8):1073-82. PMID: 16085098
Experimental and computer simulation methods have been used to investigate the significance of beam steering as a potential source of error in pulsed-wave flow velocity estimation. By simulating a typical...
