The superior vena cava syndrome is due to the increased venous pressure in the upper torso, neck and head, caused by the obstruction of the superior vena cava. Both external and internal factors cause obstruction (95% are malign causes), and the most severe manifestation is represented by cerebral edema that can even lead to coma. The diagnostic algorithm for the superior vena cava syndrome is ...

Contrast M-mode and two-dimensional ultrasonography of the inferior vena cava were performed in 65 patients with various acquired and congenital cardiac disorders. After saline was injected into a peripheral arm vein, the inferior vena cava was visualized by both methods in 60 patients (92%). The M-mode approach was better for correlating the appearance of contrast within the inferior vena cava...

Dysgenesis of the inferior vena cava is rare but it is being increasingly diagnosed by cross-sectional imaging techniques. Patients are usually asymptomatic with abnormalities detected incidentally. An 11 year old boy presented with a 10 day history of fever, vomiting and abdominal pain, which progressed to his back and lower limbs. Magnetic resonance imaging, computerised tomography and Dopple...

YSTEMIC venous anomalies, such as persistent left superior vena cava and absent inferior vena cava, are not so rare in various congenital heart diseases.1) Preoperative identification of these anomalous systemic venous connections is clinically important, because their presence necessitates modified technique for venous cannulation of cardiopulmonary bypass. In cases of persistent left superior...

Lacerations of the inferior vena cava are associated with a high mortality and may be difficult to repair. The majority of injuries are due to penetrating trauma. Rapid transportation to definitive surgical care with effective resuscitation may improve mortality. Surgical management includes adequate treatment of hypovolemic shock due to blood loss. Placement of intravenous infusion sites below...

We report a case of an indwelling inferior vena cava filter that penetrated the IVC wall after Whipple's pancreatico-duodenectomy procedure performed in a patient with ampullary carcinoma, resulting in right ureteral injury and obstruction with subsequent hydroureter and hydronephrosis. This was incidentally discovered on a computed tomography scan performed as routine follow up to evaluate the...

The renal veins drain the kidney into the inferior vena cava and unite in a variable fashion to form the renal vein. The left renal vein is normally located in front of the aorta. However, the retro-aortic renal vein may course posterior to the aorta due to embryological developmental anomalies. During educational dissection, a rare variation of the left renal vein was found in a 66-year old ma...

INTRODUCTION Superior vena cava (SVC) obstruction secondary to central venous catheterization is an increasingly recognized complication. CASE PRESENTATION We present two cases of superior vena cava obstruction secondary to indwelling central venous catheters used for haemodialysis access. One of the patients developed the unusual complications of torrential epistaxis and haemoptysis, which h...

We have previously reported our experience in inferior vena cava resection and reconstruction techniques during liver transplantation for Budd-Chiari syndrome. Herein, we present on a case that demonstrates the importance of experience in complex vascular reconstruction techniques for living donor liver transplantation. A 15-year-old boy was scheduled for living donor liver transplantation for ...

Deep vein thrombosis and pulmonary embolism are a significant health care concern, representing a major source of mortality and morbidity. In order to understand the pathophysiology of thrombogenesis and thrombus resolution, animal models are necessary. Mouse models of venous thrombosis contribute to our understanding of the initiation, propagation, and resolution of venous thrombus, as well as...
