Symptomatic developmental venous anomalies
Developmental Venous Anomalies are a normal variant that may be associated with other cerebral vascular malformation. They have bean previously referred to Venous angiomas. DVAs are the most frequently encountered cerebral vascular malformation and their incidence is reported to be high as2.6%. …

V for Venous Pressure
… and noninvasive methods to measure central venous pressure and central arterial pressure. Force-coupled ultrasound imaging of blood vessels is a process which outputs ultrasound images containing at least one segmented blood vessel of interest and assigns a force to each image. Data is …

Preventing Retained Central Venous Catheter Guidewires
Whole central venous catheter (CVC) guidewire retention is an iatrogenic error, with an incidence of 1:3,167, a morbidity of 4-53%, mortality of 4-6% and is a never event. Since 2011, health policy has mandated that all hospitals must implement national safety guidance to prevent this error, …

Venous materials towards interactive fluidic mechanism
This thesis proposes the vision of Venous Materials which intends to explore the idea that fluid can be considered and manipulated as a tangible digital-physical element for interaction design. Venous Materials suggests a new approach to design interactive materials with means of designing fluidic …

Magnetic Resonance Imaging of Cerebral Venous Oxygenation
Cerebral venous oxygenation (Yᵥ) is an important biomarker for brain diseases. My dissertation consisted of two studies. The first study aims to investigate the regional Yᵥ in hypertension. Hypertension is known to cause cerebral hypoperfusion and cortical atrophy but its impact on Yᵥ is not yet …

Serial Monitoring of Portal Venous Pressure/flow
… 중 개복 후, 문맥 재관류 후 그리고, 비장절제 후에 경시적으로 문맥압(portal venous pressure, PVP)과 문맥혈류량(portal venous flow, PVF)을 모두 측정한 13명의 생체부분간이식 환자들을 대상으로 하였다. 추가로 이식편의 유순도(compliance: PVF/PVP) 및 이식편의 단위 중량당 유순도(ml/min/mmHg/g)를 계산하였다. 비장절제는 이식편을 심은 후에도 문맥고혈압(>20mmHg)이 지속되거나 술 전 현저한 비 종대 및 전혈구감소증(pancytopenia)을 보인 환자들에 …

Computer-assisted Workflow Recognition for Central Venous Catheterization
… the development of a system for training central venous catheterization. The procedure includes many tasks that must be performed in a predetermined order. This system, Central Line Tutor, is able to provide trainees with feedback about their performance by evaluating their compliance to proper …

Effect of Lateral Positioning on Central Venous Pressure
… the effects of lateral positioning on central venous pressure. It was hypothesized that lateral positioning would not significantly change the central venous pressure so long as the subjects were placed on the same horizontal plane for both supine and lateral measurements. It was also …

Soluble urokinase plasminogen activator receptor in venous ulcers
… therapy remains the only treatment option for venous ulcers with<br/><100% success. A better understanding of the mechanisms regulating venous<br/>ulcer healing might give rise to better treatments.<br/>Urokinsae plasminogen activator receptor (uPAR), a GPI anchored 3‐domain<br/>protein exists …

The incidence and prevention of Postoperative Venous Thrombosis
… thrombosis has been reported in the literature. Venous thrombosis and its sequel, pulmonary embolus account for 12. 5% of all postoperative deaths and is the single greatest threat to recovery after surgical operations. This study was undertaken to investigate the incidence of postoperative deep …

VENOUS THROMBOEMBOLISM IN SOUTHERN SWEDEN EPIDEMIOLOGY AND RISK FACTORS
Despite the fact that venous thromboembolism (VTE) is an important cause of morbidity and mortality there is still insufficient information on VTE risk factors and patient characteristics in the general population. Previously published incidences of VTE (deep venous thrombosis [DVT] and pulmonary …

Imaging Studies of the Canine Cervical Vertebral Venous Plexus
The internal vertebral venous plexus (IVVP) is an extensive vascular network recently implicated in various human and canine spinal disorders. Nevertheless, little recent information is available regarding normal anatomy of canine IVVP and its role in acute spinal injuries. The objectives of the …

Non-invasive Optoacoustic Monitoring of Neonatal Cerebral Venous Oxygen Saturation
… to quickly and accurately measure cerebral venous oxygen saturation. While diagnosis of neonatal cerebral hypoxia is limited, treatment with cerebral hypothermia has shown to decrease both mortality and long-term neurodevelopmental disabilities in neonates with moderate to severe cerebral …

DYNAMIC BEHAVIOR AND LINEAGE PLASTICITY OF THE PULMONARY VENOUS ENDOTHELIUM
… in other settings, we investigated the role of venous endothelial cells in endothelial regeneration after adult lung injury. Using single cell transcriptomics, we identified the norepinephrine transporter Slc6a2 as a marker of pulmonary venous endothelial cells and targeted that locus to …

Molecular and morphological studies on non-healing venous leg ulcers.
… ulcers have various underlying causes, such as venous or arterial insufficiency, diabetes, or vasculitis. Non-healing venous leg ulcers represent a condition characterized by excessive inflammation and presence of bacteria. The overall aim of this thesis has been to explore the pathogenesis of …

Arterial and venous adaptations to short-term handgrip exercise training
… inflow (Ainf) [r=0.54; p=0.012] and resting venous outflow (Vout) [r=0.56; p=0.016]. Lastly, HG strength was associated with Vcap [r=0.57; p=0.007] and Vout [r=0.67; p=0.001]. The 2nd study examined the relationship between FVF and exercise tolerance (ExT) in 20 patients with HF [age: 59 ± 13 …

Central Venous Pressure Reference Points Measured on Post-Mortem Subject
<p>Hemodynamically the central venous pressure should be the same in both the supine and lateral positions. The accurate determination of an external zero reference level corresponding with mid right atrial level would make possible reliable measurements in either position. The purpose of this …

Minimally invasive treatment of venous insufficiency using endovenous laser ablation
Background Venous insufficiency is very common and causes significant quality of life (QoL) impairment. Conventional open surgery featuring junction ligation, stripping of the axial vein and phlebectomy is known to offer significant benefits over conservative management; resulting in improved QoL. …
