Stenosis or occlusion of central veins in hemodialysis patients is common, especially with previous intravascular catheter or device use. Superior vena cava (SVC) obstruction is emerging as a frequent chronic complication of central vein cannulation that not only jeopardizes the availability of vascular access for hemodialysis, but can become a life-threatening emergency. Clinical features of SVC syndrome can be subtle or dramatic, including facial swelling and shortness of breath, which require expeditious attention and intervention...

We present a case of 13-year-old female with Turner syndrome (TS), who presented with unexplained lower limbs swelling and ejection systolic murmur at the left second intercostal space. Suspicion of mild aortic coarctation was made by echocardiography. Computed tomography angiography (CTA) showed a complete interruption of the aortic arch (IAA) below the left subclavian artery with persistent left superior vena cava (PLSVC) and absent right SVC, defined as an isolated PLSVC. The patient underwent successful surgical correction after unsuccessful trial of transcatheter stent placement...

OBJECTIVE: Poor survival following surgical palliation for hypoplastic left heart syndrome (HLHS) raises the question of the need for a paradigm shift. This is the first human study to investigate the possibility of primary "in-series" palliation in neonates and infants with HLHS in an acute setting with the aid of 2 types of mechanical assist: superior vena cava (SVC)-to-pulmonary artery (PA) pump assist and SVC-to-right atrium (RA) oxygenation assist. METHODS: By rearranging the cannula sites and flow rates for modified ultrafiltration, 2 types of mechanically assisted bidirectional cavopulmonary shunt (BCPS) circulation were simulated for 20 minutes...

Intra-cardiac extension of tumour thrombus of follicular carcinoma of thyroid is uncommon. We report a case of advanced thyroid carcinoma where tumour thrombus was well profiled with CT scan and transesophageal echo images and extension was noted from SVC into right atrium, with clinical features of superior vena cava syndrome. The clinical significance of the "ring sign" is discussed.

Total absence of superior vena cava (SVC) is a very rare anomaly, and the patient usually suffers from SVC syndrome or conduction disturbances. We report an asymptomatic 27 year-old male, with complete absence of SVC. Transthoracic echocardiography and computed tomography demonstrated the absence of SVC and other congenital cardiac anomalies, but the presence of prominent collateral vessels that allow a sufficient venous return.

The obstruction of blood flow through the superior vena cava (SVC) into the right atrium may present as a severe clinical syndrome. One of the benign causes of SVC obstruction is the long-term use of indwelling catheters and wires, increasing the chances of SVC thrombosis. The treatment of the benign SVC syndrome is focused on achieving long-term durability and patency of the superior venocaval system and normal life expectancy. We report the successful surgical management of a patient with severe symptomatic SVC syndrome and emphasize technical details that might be of value in treating this challenging pathologic condition...

INTRODUCTION: Bronchogenic cysts, commonly located in the mediastinum or lung parenchyma, arise from abnormal budding of the tracheobronchial tree. Since an unknown percentage of asymptomatic adult patients with bronchogenic cysts remain undiagnosed, the true natural history ofthese cysts in adults is uncertain and the available series reflect a significant selection bias in favor of the symptomatic individual. CASE REPORT: We present the case of a 42-year-old female who presented with adull central chest pain, which gradually worsened overseveral weeks...

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e...

PURPOSES: Resection and reconstruction of the superior vena cava (SVC) is used for the complete resection of advanced lung cancer and mediastinal tumors. However, the optimal postoperative management for this procedure remains to be elucidated. METHODS: 1897 patients with lung cancer and/or mediastinal tumors underwent surgical resection at our institute. Among them, 12 patients underwent combined resection and replacement with a vascular graft of the SVC. Preoperative SVC syndrome was noted in 4, and preoperative chemo and/or radiotherapy were used in 2...

We present a rare case of intracardiac myeloid sarcoma (MS) of acute myeloid leukemia (AML) and who responds completely well to low-dose radiotherapy. This 19-year-old young man initially presented with AML and received standard chemotherapy followed by allogeneic hematopoietic stem cell transplantation (HSCT). However, he developed intracardiac isolated MS relapse with the presentation of exertional dyspnea and superior vena cava (SVC) syndrome 3 years later. He then received radiotherapy with 24 Gy at a 12 daily fractions using forward "field in field" intensity modulated radiotherapy technique...

BACKGROUND: Hemodialysis (HD) catheters are frequently inserted into the superior vena cava (SVC), and can lead to thrombotic complications. However, to our knowledge, HD catheter-related thrombosis leading to subsequent SVC syndrome, bacteremia, and pulmonary emboli has not been described. CASE PRESENTATION: A 28-year-old dialysis-dependent woman with IgA nephropathy developed facial swelling, head pressure, headache, nausea, dizziness and fever 6 weeks after right internal jugular (IJ) HD catheter placement...

SVC obstruction is a rare acute complication after bicaval cardiac transplantation and can be catastrophic for the patient. Herein, we report the case of a child who developed SVC thrombosis causing acute SVC syndrome nine days after heart transplantation. Thrombolysis was successfully performed using the AngioJet(™) system and subsequent balloon angioplasty with re-establishment of flow. This procedure allowed for revascularization without repeat sternotomy or stent implantation. The patient is well without recurrence at last follow-up...

BACKGROUND: The vast majority of superior vena cava (SVC) syndromes are of malignant causes, but with growing use of indwelling central catheters and implanted cardiac devices, benign SVC syndromes are becoming more frequent. The main objective of this study is to evaluate long term outcome in patients treated for benign SVC syndrome by endovascular techniques. METHODS: Forty-four patients, 26 men and 18 women, mean age 56, treated for benign SVC syndrome using endovascular techniques between 2002 and 2015 were included...

The perioperative management of patients suffering from extensive superior vena cava (SVC) thrombus complicated by SVC syndrome presents unique challenges. The anesthesiologist needs to be prepared for possible thrombus dislodgement resulting in pulmonary embolism and also has to assess the need for fluid resuscitation given the dangers of massive intravenous fluid application via the upper extremities. We present our perioperative approach in management of a patient scheduled for right hepatectomy who was previously diagnosed with extensive SVC and right atrial (RA) thrombus complicated by SVC syndrome...

OBJECTIVES: Hemodialysis (HD) patients with superior vena cava (SVC) occlusion have limited access options. Femoral access is commonly employed but is associated with high complication rates. Hemodialysis Reliable Outflow (HeRO) catheters can be used in tunneled catheter-dependent (TCD) patients who have exhausted other access options. The HeRO graft bypasses occlusion and traverses stenosis with outflow directly into the central venous circulation. At our institution we have used the inside-out central venous access technique (IOCVA) to traverse an occluded vena cava for HeRO graft placement...

Radiation therapy (RT) is the standard of care for cases of superior vena cava (SVC) syndrome secondary to metastatic adenopathy. Histologies vary in radiosensitivity and response time, making alternative therapies such as chemotherapy and/or intravenous stenting preferable alternative options for certain diagnoses. Metastatic urothelial carcinoma is a particularly rare cause of SVC syndrome with only 3 cases reported in the literature. Consequently, optimal management remains challenging, particularly in cases of high tumor burden...
