- The Tromped: A Solution for Flight-Related Deep Vein Thrombosis? Collins, Carolyn; Fitzgerald, Patricia; Kennedy, David M.; Corrigan, Thomas; Jerrams, Stephen; Bouchier-Hayes, David J. // Angiology;Feb/Mar2008, Vol. 59 Issue 1, p72
Flight-related deep vein thrombosis (DVT) is well recognized. Reduced venous return occurs during immobility. This alteration in venous hemodynamics may contribute to DVT development. A prototype design of an in-flight exercise device to stimulate ambulatory bloodflow while seated has been...
- Improved instrumentation for blood flow velocity measurements in the microcirculation of small animals. de Mesquita, Jayme Alves; Bouskela, Eliete; Wajnberg, Eliane; de Melo, Pedro Lopes // Review of Scientific Instruments;Feb2007, Vol. 78 Issue 2, p021101
Microcirculation is the generic name of vessels with internal diameter less than 100 Î¼m of the circulatory system, whose main functions are tissue nutrition and oxygen supply. In microcirculatory studies, it is important to know the amount of oxyhemoglobin present in the blood and how fast it...
- Arterial Access Site Closure with a Novel Sealing Device: Duett. Heyer, Gunter; Atzenhofer, Karl; Meixl, Herbert; Lampersberger, Christian; Gershony, Gary // Vascular Surgery;May/Jun2001, Vol. 35 Issue 3, p199
Focuses on the association of arterial access site closure following percutaneous endovascular procedures with patient discomfort and local complications. Introduction of Duett as vascular sealing device; Hemostasis at the groin site; Characterization of the vascular sealing device.
- Anomalous Course ofthe Common Carotid Arteries: CT and MRA Illustration. Walsh, Daniel W.; Ho, Vincent B.; Borke, Rosemary C.; Rovira, Miguel J. // Angiology;Mar1998, Vol. 49 Issue 3, p235
Recognition of normal vascular variations is tantamount to accurate diagnosis and intervention. The authors describe an unusual course for the common carotid arteries that was incidentally identified on routine cervical spine x-ray films. The embryonic events leading to this normal variant are...
- Diagnosis and management of deep vein thrombosis of the upper extremity: a review. Baarslag, Henk J.; Koopman, Maria M. W.; Reekers, Jim A.; van Beek, Edwin J. R. // European Radiology;Jul2004, Vol. 14 Issue 7, p1263
Deep vein thrombosis of the upper extremity is an increasing clinical problem due to the use of long-term indwelling catheters for chemotherapy or long-term feeding. The clinical diagnosis is difficult to make, and various imaging modalities have been used for this purpose. The use of...
- Rare Case of Spindle Cell Haemangioma. CHAVVA, SUNANDA; PRIYA, M. HIMA; GARLAPATI, KOMALI; PRASAD REDDY, G. SIVA; GANNEPALLI, ASHALATA // Journal of Clinical & Diagnostic Research;Jun2015, Vol. 9 Issue 6, p19
Spindle cell haemangioma (SCH) is a benign vascular lesion which usually occurs on distal extremities. It was previously regarded as haemangioendothelioma and was initially perceived to be low grade angiosarcoma. They are characterized by cavernous blood vessels and spindle cell proliferation....
