As superior vena cava syndrome leads to aberrant blood flow, tracer injected to an arm vein might partly circumvent the pulmonary capillary bed and accumulate in well-perfused anatomical structures. In this case, next to the commonly described liver enhancement, more prominent pseudo-uptake of ...
We present a case of peripherally inserted central catheter (PICC) port placement where the catheter had been malpositioned to the persistent left superior vena cava. Despite the obvious elevation of the P-wave signaling proximity of the catheter tip to the sinus node, the catheter was not in ...
Thrombosis of the superior vena cava leads to obstruction of venous outflow of the head and upper extremities and causes severe clinical symptoms. The management of SVC syndrome depends on aetiology and acuity at clinical presentation and ranges from conservative medical treatment to bypass surgery. ...
例句Because this leads to various diseases, not a single illness, AIDS is referred to as asyndrome. 由于艾滋病会导致多种疾病而不是单一的,因此艾滋病是一种综合症。 概述 概述 上腔静脉综合征( superior vena cava syndrome,SVCS)指上腔静脉回到右心房的血流完全性或不完全性受阻所致的临床综合征,属于急...

50.3.1.1Superior vena cava stenosis Stenosis ofsuperior vena cavais more commonly related tomalignancyor iatrogenic causes, such as thrombosis due to the presence of electronic device leads (e.g., pacemaker or implantable cardiac defibrillator)[29], less frequently it may be apostoperative complicatio...
Superior vena cava syndrome (SVCS), or superior vena cava obstruction (SVCO), is usually the result of the direct obstruction of the superior vena cava (SVC) by malignancies such as compression of the vessel wall by right upper lobe tumours or thymoma and/or mediastinal lymphadenopathy. The ...
The purpose of this study was to assess the feasibility of stent dilation of venous obstructions/occlusions to permit transvenous pacing lead implantation. Innominate vein or superior vena cava (SVC) obstruction may preclude the implantation of transvenous pacing leads. Patients with d-transposition ...
It is important to recognize the potential importance of right-left shunt (RSVC-LA), which leads to a high volume of systemic venous return. Any connection between the venous and arterial systems poses a substantial risk of brain abscess and paradoxical embolization [2, 3]. The VGAM is the...
Thirty-seven leads, with a mean dwell time of 5.8 years (range 2–12 years), were extracted. After extraction, 6 patients (37.5%) received an SVC stent. Balloon angioplasty was performed before stenting in 5 cases (31.3%). There was 1 major complication (6.3%) due to an SVC tear ...
