Abstract
Superior vena cava syndrome (SVCS) is a medical emergency that encompasses an array of signs and symptoms due to obstruction of blood flow through the superior vena cava (SVC). It poses a significant healthcare burden due to its associated morbidity and mortality. Its impact on the healthcare system continues to grow due to the increasing incidence of the condition. This incidence trend has been attributed to the growing use of catheters, pacemakers, and defibrillators, although it is a rare complication of these devices. The most common cause of SVCS remains malignancies accounting for up to 60% of the cases. Understanding the pathophysiology of SVCS requires understanding the anatomy, the SVC drains blood from the right and left brachiocephalic veins, which drain the head and the upper extremities accounting for about one-third of the venous blood to the heart. The most common presenting symptoms of SVCS are swelling of the face and hand, chest pain, respiratory symptoms (dyspnea, stridor, cough, hoarseness, and dysphagia), and neurologic manifestations (headaches, confusion, or visual/auditory disturbances). Symptoms generally worsen in a supine position. Diagnosis typically requires imaging, and SVCS can be graded based on classification schemas depending on the severity of symptoms and the location, understanding, and degree of obstruction. Over the past decades, the management modalities of SVCS have evolved to meet the increasing burden of the condition. Here, we present an umbrella review providing an overall assessment of the available information on SVCS, including the various management options, their indications, and a comparison of the advantages and disadvantages of these modalities.

Abstract
The superior vena cava syndrome (SVCS) has been frequently reported to be secondary to malignancy, specifically, small cell bronchogenic carcinoma and non-Hodgkin's lymphoma. There is some data suggesting causes like postprocedural hematomas. We aim to describe a case of a patient who developed SVCS secondary to a mediastinal hematoma secondary to epicardial pacer leads (postprocedural). Our case is about a 75-year-old male with a past medical history of coronary artery disease and coronary artery bypass graft (CABG) who presented to the Emergency Department (ED) with moderate-to-severe right axillary pain radiating to the ipsilateral side of the neck, arm, and chest, associated to right temporal headache. A computed tomography angiography (CTA) of the chest was indicated at the time and revealed a hematoma with an active extravasation within the right superior anterior mediastinum, outside the pericardium. The patient was admitted to the Cardiovascular Intensive Care Unit (CVICU) and was started on nicardipine as his blood pressure in the ED was 217/125 and remained elevated despite proper pain management. A repeat CT scan of the chest showed a regressing hematoma that coincided with an improvement of the symptoms. This case highlights the importance of the complications of anterior mediastinal hematoma. The superior vena cava syndrome can develop after cardiologic procedures, after the implantation of devices. Prompt clinical diagnosis, including imaging, and treatment are necessary to manage this condition.

Abstract
The superior vena cava syndrome (SVCS) is caused by compression, invasion, and/or thrombosis of the superior vena cava and/or the brachiocephalic veins. Benign SVCS is separated from malignant SVCS. SVCS comprises a broad clinical spectrum reaching from asymptomatic cases to rare life-threatening emergencies with upper airway obstruction and increased intracranial pressure. Symptoms are correlated to the acuity and extent of the venous obstruction and inversely correlated to the development of the venous collateral circuits. Imaging is necessary to determine the exact underlying cause and to guide further interventions. Interventional therapy has widely changed the therapeutic approach in symptomatic patients. This article provides an overview over this complex syndrome and focuses on interventional therapeutic methods and results.

Abstract
OBJECTIVE The objective of this study was to conduct a systematic review of case reports documenting the development of antiphospholipid syndrome or antiphospholipid syndrome-related features after an infection. METHODS We searched Medline, EMBASE, Web of Science, PubMed ePubs, and The Cochrane Library - CENTRAL through March 2015 without restrictions. Studies reporting cases of antiphospholipid syndrome or antiphospholipid syndrome-related features following an infection were included. RESULTS Two hundred and fifty-nine publications met inclusion criteria, reporting on 293 cases. Three different groups of patients were identified; group 1 included patients who fulfilled the criteria for definitive antiphospholipid syndrome (24.6%), group 2 included patients who developed transient antiphospholipid antibodies with thromboembolic phenomena (43.7%), and group 3 included patients who developed transient antiphospholipid antibodies without thromboembolic events (31.7%). The most common preceding infection was viral (55.6%). In cases that developed thromboembolic events Human immunodeficiency and Hepatitis C viruses were the most frequently reported. Parvovirus B19 was the most common in cases that developed antibodies without thromboembolic events. Hematological manifestations and peripheral thrombosis were the most common clinical manifestations. Positive anticardiolipin antibodies were the most frequent antibodies reported, primarily coexisting IgG and IgM isotypes. Few patients in groups 1 and 2 had persistent antiphospholipid antibodies for more than 6 months. Outcome was variable with some cases reporting persistent antiphospholipid syndrome features and others achieving complete resolution of clinical events. CONCLUSIONS Development of antiphospholipid antibodies with all traditional manifestations of antiphospholipid syndrome were observed after variety of infections, most frequently after chronic viral infections with Human immunodeficiency and Hepatitis C. The causal relationship between infection and antiphospholipid syndrome cannot be established, but the possible contribution of various infections in the pathogenesis of antiphospholipid syndrome need further longitudinal and controlled studies to establish the incidence, and better quantify the risk and the outcomes of antiphospholipid-related events after infection.

Abstract
Background: Intracranial pressure (ICP) monitoring is not routinely used during complex spinal deformity correction surgery. The authors report a 66-year-old male who during thoracolumbar deformity surgery required the placement of an ICP monitor due to the underlying history of a superior vena cava syndrome (e.g., s/p right jugular stent). Case Description: A 66-year-old male with multiple prior lumbar spinal procedures presented with lower back and bilateral lower extremity pain, paresthesias, and weakness. He had a history of chronic left internal jugular and brachiocephalic venous occlusion (e.g., he had a right internal jugular stent). During deformity surgery, a frontal intraparenchymal ICP monitor was placed. During the early portion of the operation, bed adjustments (increasing reverse trendelenburg position) were required to compensate for ICP elevations as high as 30 mm Hg. A subsequent inadvertent durotomy during decompression lowered the ICP to <5 mm Hg; no further ICP spikes occurred. His postoperative course was uneventful, and 14-month later, he was dramatically improved. Conclusion: ICP monitoring may be a useful adjunct for patient safety in selected patients who are at risk for developing intracranial hypertension during extensive spinal deformity surgery.

Abstract
BACKGROUND Cerebrospinal fluid diversion is one of the most frequent neurosurgical procedures across the world and can be challenging in select patients who fail standard distal drainage sites. OBJECTIVE To present the case of a woman after failing peritoneal, pleural, and atrial distal drainage sites who underwent a thoracoscopic-assisted ventriculo-azygous vein shunt placement. METHODS A 32-year-old woman presented to our hospital with long-standing history of hydrocephalus and shunt dependence. She had failed peritoneal and atrial shunts secondary to infection, scarring, and clot formation. At presentation, she had a pleural shunt in place and developed a large pleural effusion with shortness of breath. RESULTS She was taken to the operating room where a thoracoscopic-assisted ventriculo-azygous vein shunt was placed through a mini-thoracotomy. Postoperatively, she has not required a shunt revision in >2 years of follow-up. CONCLUSION When other distal sites fail, our case report illustrates a novel surgical technique capable of being performed through a multidisciplinary approach.

Abstract
Antiphospholipid syndrome is an autoimmune disorder characterized by a hypercoagulable state, leading to arterial and venous thrombosis. We present a 23-year-old patient, suspected of having Budd-Chiari syndrome due to antiphospholipid syndrome, who developed severe and progressive hypoxemia, requiring prolonged mechanical ventilation. After a detailed but unsuccessful workup, a contrast CT scan revealed an occluded superior vena cava and azygos vein-superior vena cava junction and massive right-to-left shunting through a network of systemic to pulmonary venous collaterals. Restoring normal blood flow from the azygos vein into the right atrium by stenting the azygos-superior vena cava junction resolved the hypoxemia immediately. Within the same procedure, the hepatic outflow obstruction was successfully treated by stenting a severe stenosis of the suprahepatic inferior vena cava caused by calcified thrombus.

Abstract
Superior vena cava syndrome results from the obstruction of blood flow through the superior vena cava and is most often due to thoracic malignancy. However, benign etiologies are on the rise secondary to more frequent use of intravascular devices such as central venous catheters and pacemakers. Although rarely a medical emergency, the symptoms can be alarming, particularly to the patient. Traditionally, superior vena cava syndrome has been managed with radiotherapy and chemotherapy. But interventional endovascular techniques have made inroads that offer a safe, rapid, and durable response. In many cases, it may be the only reasonable treatment. Because of this, an approach to endovascular treatment of this condition must be in the armamentarium of the interventional radiologist. This review will provide the reader with an insight into the etiology, pathophysiology, and various management principles of superior vena cava syndrome. The focus will be on understanding the techniques used during various endovascular interventions, including angioplasty, stenting, and pharmacomechanical thrombolysis. Discussion will also be centred on possible complications and current evidence as well as controversies regarding these approaches.

Abstract
Superior vena cava syndrome (SVCS) is usually caused by extrinsic compression or invasion of the superior vena cava (SVC) by malignant tumors involving mediastinal structures. Although thymomas are well-known causes of SVCS, cases of SVCS caused by malignant thymomas protruding into adjacent vessels draining the SVC with thrombosis have been very rarely reported worldwide. We experienced a 39-year-old female patient with SVCS that developed after the direct invasion of the left brachiocephalic vein (LBCV) and SVC by an anterior mediastinal mass with a high maximum standardized uptake value on the chest computed tomography (CT) and positron emission tomography-CT. Based on these results, she underwent en bloc resection of the tumor, including removal of the involved vessels, and was eventually diagnosed as having a type B2 thymoma permeating into the LBCV and SVC. We present this case as a very rare form of SVCS caused by an invasive thymoma.
