Etiologic prevalence of superior vena cava syndrome

OBJECTIVES: Superior vena cava syndrome (SVCS) is an uncommon disease which receives usually bad prognostic. In order to study the prevalence of the different etiologies we have reviewed retrospectively 17 documented cases of SVCS in the last 5 years. METHODS: The range of age was between 43 and 80 years Sex distribution was 16 males and 1 female. RESULTS: Malignant pathology was by large the most common etiology. Oat cell and squamous cell carcinoma account each for 20%, adenocarcinoma for 18%, undifferenciated carcinoma for 12% and Hodgkin's disease for 6%. Among the benign causes we have found a case of retroesternal goiter.     

Diagnosis and management of superior vena cava syndrome

Superior vena cava (SVC) syndrome is a relatively common complication of lung cancer or lymphoma, and in fact is often the initial manifestation of these diseases. However, benign causes also exist, and physicians should not automatically assume that SVC syndrome is due to cancer. A definitive histologic diagnosis of cancer should be obtained before starting radiotherapy or chemotherapy to treat SVC syndrome.     

Primary malignant lymphoma of superior vena cava

A 78-year-old woman suffered from superior vena cava (SVC) syndrome. Computed tomography and angiography revealed a mass within the SVC. The SVC was resected via median sternotomy, followed by reconstruction using an artificial graft. The resected specimen showed a polypoid tumor within the SVC that had invaded the wall of the SVC. Histologic diagnosis was diffuse large-cell non-Hodgkin's lymphoma. Most surrounding lymph nodes showed reactive swelling, but one showed a partial microscopic metastasis. These pathologic findings indicated that the tumor was an SVC-originating malignant lymphoma. The patient is now alive and tumor-free 65 months after the operation.     

Suspected superior vena cava syndrome: the role of the Swan-Ganz catheter

The use of the Swan-Ganz flow-directed catheter in establishing the diagnosis of the superior vena cava syndrome in two patients (one with Hodgkin's disease and the other with carcinoma of the lung) is described. A pressure tracing showing elevated pressure above the obstruction without respiratory or cardiac fluctuations is characteristic of obstruction of the superior vena cava.     

Left-sided superior vena cava: diagnosis by magnetic resonance imaging

We describe a case of left-sided superior vena cava. The diagnosis was suggested by chest radiograph after central venous catheter placement. This was subsequently confirmed by magnetic resonance imaging.     

Study of superior vena cava syndrome--aetiopathology, diagnosis and management

Thirty two patients of superior vena cava syndrome (SVCS) were studied. Clinical features noted were diffuse neck swelling, breathlessness, chest pain, engorged neck veins, facial swelling and dilated engorged veins over chest wall. Radiography revealed a superior mediastinal mass in 31.2% of patients and right upper lobe mass in 50% patients. FNAC of lung showed aetiology in 34.5% patients and lymph node biopsy in 31.2% patients. Aetiology of SVCS was benign in 12.5% patients and malignant in 87.5% patients. Squamous cell carcinoma was the commonest cause of SVSC. Radiotherapy proved to be the most beneficial form of treatment. The mean survival period in patients due to malignant etiology was 6 months.     

Computed tomography-guided central venous catheter placement in a patient with superior vena cava and inferior vena cava occlusion

Erythropoietin (EPO) is a glycoprotein hormone produced principally by the kidney and is the major stimulus for erythropoiesis. Recombinant human EPO has now been biosynthesized and is available for clinical use, particularly in patients with renal failure. EPO has been reported to be effective in treating anaemia due to chronic renal failure. It has been used in pregnancy to correct anaemia following renal transplantation with graft dysfunction. We report here the case of a post-renal transplant patient who became pregnant and developed severe anaemia which was not related to iron, B12, or folate deficiency. Her anaemia was successfully treated with EPO with no evidence of rejection or significant graft dysfunction following therapy. She tolerated EPO very well, and there was a successful outcome of the pregnancy. This case has encouraged us to conclude that EPO has a useful role in the treatment of anaemia in pregnant women following renal transplantation.     

Thrombosis of the superior vena cava, hemolytic anemia and hyper-homocysteinemia]

A case of zoonotic Mycobacterium tuberculosis infection in a marmoset (Callithrix jacchus) is reported. Genomic typing of the relevant M. tuberculosis isolates strongly suggests that the marmoset, which was kept as companion animal, acquired the disease from an infected member in the household who had been treated for pulmonary tuberculosis 8 years prior to this case.     

Anomalous drainage of right superior vena cava into the left atrium

Tracheal glomus tumors are extremely rare. We present herein the case of a 43-year-old man with hoarseness who was found to have a glomus tumor arising from the lower trachea. Bronchoscopy and chest computed tomography revealed a polypoid mass in the membranous portion of the trachea just above the carina. The patient underwent successful tracheal sleeve resection and reconstruction. A pathologic diagnosis of a glomus tumor with clear surgical margins was subsequently confirmed, and the patient is well 20 months postoperatively with an intact anastomosis.     

Catheter-induced thrombus in the superior vena cava diagnosed by transesophageal echocardiography

BACKGROUND: To present the role of transesophageal echocardiography (TEE) in the diagnosis and management of catheter-related superior vena cava thrombosis. CASE HISTORY: A 42-year-old woman with severe Crohn's disease presented with septic shock and pulmonary embolism three weeks after emergency laparotomy and ileocolic resection for small-bowel perforation with peritonitis. Cardiopulmonary evaluation with ECG, pulmonary artery catheter and TEE demonstrated no evidence of acute myocardial ischemia or ventricular dysfunction; hemodynamic indices were consistent with severe sepsis. TEE revealed a large sheathing thrombus surrounding a central venous catheter used for parenteral nutrition. A spiral CT scan of the chest confirmed multiple peripheral pulmonary emboli. Treatment consisted of systemic anticoagulation and antibiotics. To avoid further pulmonary embolism, the central venous catheter was not removed until six days later under TEE monitoring, which revealed that the thrombus was firmly adherent to the superior vena cava. The patient made an uneventful recovery and was discharged from hospital on long-term anticoagulant therapy. CONCLUSION: In a case of catheter-induced superior vena cava thrombosis with septicemia and pulmonary embolism, bedside TEE was very helpful to make the correct diagnosis early, assess thrombus size during anticoagulation, and monitor cardiac performance and thrombus disposition during central venous catheter removal.     

Discovery of left-sided superior vena cava during central venous catheterization

PURPOSE: To report a child with the mitochondrial cytopathy of Pearson syndrome and zonular cataract. METHOD: Case report. We describe a 6-year-old boy with Pearson syndrome. RESULTS: At age 3 years, the boy developed secondary strabismus caused by bilateral zonular cataract. Subsequently, he underwent successful bilateral cataract extraction with intraocular lens implantation. Postoperative visual acuity with best correction was RE, 20/25 and LE, 20/40. CONCLUSIONS: Children with Pearson syndrome should be examined ophthalmologically to rule out zonular cataract and possible amblyopia. Mitochondrial cytopathies such as Pearson syndrome should be included in the differential diagnosis of congenital and early juvenile cataract.     

Metastatic carcinoma of the prostate presenting as a superior vena cava syndrome

A 75-year-old patient presented with a superior vena cava syndrome (SVCS) lasting 3 years. A prostatic carcinoma was found and a supraclavicular lymph node biopsy specimen disclosed metastasis of the prostatic carcinoma. Antiandrogen and luteinizing hormone-releasing hormone analogue therapy produced a marked improvement. Prostatic carcinoma, although a very rare cause, must be considered in the diagnosis of cases of SVCS with a protracted course, since it is a treatable disease.     

Leiomyosarcoma of the superior vena cava. A first case with resection

Leiomysarcomas, rare malignant tumors of the veins, are located predominantly in the inferior vena cava. We report our experience with a leiomyosarcoma in the superior vena cava of a 44-year-old white man. The lesion had been locally excised and then recurred 2 1/2 years later. The recurrent tumor was widely excised and the superior vena cava was repaired with a saphenous vein patch graft. The area of the recurrence was treated with cobalt 60 therapy. Four years later, 6 1/2 years after initial treatment, the patient is alive and well without evidence of recurrence.     

Rhabdomyosarcoma in the inferior vena cava with secondary Budd-Chiari syndrome

Abdominoplasty is a common procedure in plastic surgery. Reviewing 150 patients who underwent abdominoplasty, it has been observed that 72% of the patients already had an abdominal scar. How to deal with abdominoplasty in an abdomen with a previous scar is discussed in this article.     

A case of superior vena cava syndrome caused by Klebsiella pneumoniae

A 27 yr old man presented with productive cough, fever and manifestations of superior vena cava syndrome. He was an alcoholic but had been in good health until 3 days prior to admission. The physical examination, the chest radiograph and the results of the sputum culture were compatible with Klebsiella pneumoniae pneumonia of the right upper lobe. The superior vena cava scintigram using technetium-99m showed near total occlusion of the superior vena cava, while sputum cytology, chest computed tomography, and bronchoscopy were all negative for malignant aetiology. Antibiotic therapy brought about slow resolution of the pneumonia and also of the superior vena caval obstruction. The follow-up scintigram showed normalized venous flow of the superior vena cava. To our knowledge, this is the first case of superior vena cava syndrome developed in probable association with Klebsiella pneumoniae pneumonia.
