ABSTRACT
Superior
vena cava syndrome is a rare condition that is usually caused by
malignancy, especially bronchogenic carcinoma. Idiopathic fibrosing
mediastinitis rarely leads to superior vena cava syndrome. The authors
report the case of a patient with superior vena cava syndrome caused
by idiopathic fibrosing mediastinitis. The patient had been previously
treated with internal jugular-right atrial bypass surgery with polytetrafluoroethylene,
which occluded four years later. A new internal jugular-right atrial
bypass using a spiral saphenous vein graft was then performed. After
15 years of follow-up, the patient is asymptomatic and the spiral
graft is patent by duplex scan.
Key
words: superior vena cava syndrome, fibrosis, venous thrombosis.

Superior
vena cava syndrome (SVCS) was first described by William Hunter in 1757.
Until 1990, more than 2,000 cases had been reported.1
This condition is caused by malignant tumors in 85% of the patients,
especially bronchogenic carcinoma. Currently, central venous catheterizing
for prolonged access and pacemaker placement have become significant
causes of this syndrome.2 Inflammatory diseases
of the mediastinum can rarely lead to fibrosing mediastinitis.3,4.
The authors present a case study of a patient with SVCS caused by idiopathic
fibrosing mediastinitis treated with a spiral saphenous vein graft.
CASE
REPORT
A 27 year-old
male was admitted in our Service. He complained of headaches and edema
of the face, torso and upper limbs. At physical examination, he presented
with edema and extensive collateral circulation in the torso and upper
limbs. The chest x-ray showed a right paramediastinal mass. Venography
through bilateral puncture of the upper limb showed superior vena cava
occlusion and collateral venous network. The patient underwent a median
sternotomy. A whitish and fibrotic mediastinal mass was found to be
compressing the superior vena cava. The intraoperative pathologic examination
was inconclusive for malignancy. A biopsy and a bypass from the right
internal jugular vein to the right atrium with polytetrafluoroethylene
(PTFE) were performed. The patient reported complete relief of symptoms
in the immediate postoperative period and was discharged four days after
the operation. The result of the pathological examinations evidenced
a fibrosing mediastinitis with an undetermined etiology (idiopathic).
Four years later, the patient presented recurrence of symptoms and PTFE
graft occlusion. Investigation for tuberculosis and systemic mycoses
provided negative results. The patient underwent a new right internal
jugular vein bypass in the right atrium through median sternotomy. At
this time using a spiral great saphenous vein graft (Figure 1). The
patient reported symptoms relief and was discharged four days after
the operation. The patient is being followed for a period of 15 years
with duplex scan and computed tomographic angiography (Figure 2). He
remains asymptomatic and continues to have a patent graft.

DISCUSSION
Fibrosing
mediastinitis is the most common benign cause of SVCS. Presence of a
thick and fibrotic tissue can cause compression of the superior vena
cava, leading to venous hypertension upstream. The clinical presentation
of this syndrome includes edema of the face, neck and upper limbs in
addition to facial plethora and collateral circulation in the thoracic
wall. The patient complains of feeling of weight in the head, dyspnea
and orthopnea, headaches, visual alterations, periorbital pain and coughing.1-3
Although fibrosing mediastinitis could be caused by tuberculosis and
systemic mycoses, in most cases the cause is unknown (idiopathic).
In contrast to malignant diseases, compression of the superior vena
cava due to idiopathic fibrosing mediastinitis has a slow and progressive
course. For this reason, conservative treatment is the treatment of
choice while awaiting the development of collateral circulation that,
in most cases, relieves the venous hypertension symptoms. When the clinical
treatment fails or the patient presents neurological compromise or upper
airway obstruction), invasive treatment is mandatory.1,3,5
There are many options available for this procedure, concerning the
type of conduit to be used. Doty et al. were the first to successfully
use the spiral saphenous vein in the treatment of SVCS.1
The patient remained asymptomatic with a patent and graft during a 15-year
follow-up. This technique, however, was initially described by Chiu
et al.6 as a substitute for large vessels. For SVCS caused by benign
diseases, this type of graft shows better long-term patency than synthetic
prostheses. However, some authors report complexities and time demand
in this graft confection, difficulty in handling and high rate of thrombosis
due to the long suture line.1
The PTFE is also used as a vascular substitute in the treatment of SVCS.
The PTFE is used preferably in the case of malignant disease associated
with SVCS. This preference is based on the fact that the PTFE is more
resistant to extrinsic compression than autogenous grafts. The patency
of the PTFE in this situation is difficult to evaluate because the majority
of these patients go on to die from the basic disease within a few years.
The patency reported in literature is 86% in three to five years.7
Other options available are the superficial femoral vein and homologous
grafts.7 The use of the superficial femoral
vein as a graft was described in 1951. Some authors affirm that this
type of conduit is easily handled, and is technically easier and faster
to obtain than the spiral saphenous vein graft. However, lower limb
edema after the femoral vein removal can be significant and uncomfortable.8-10
During recent years, endovascular techniques have also been used in
the treatment of SVCS.11 The experience
of angioplasty with self-expandable or balloon-expandable stents in
this situation is still restricted. However, the initial results are
promising with a success rate and primary patency of 95%. Secondary
patency is of 74% in five years; however, the need for reintervention
for restenosis is not uncommon.10 For the
time being, endovascular treatment is reserved for seriously ill patients
with a malignant disease and a low life expectancy.11
In the cases of SVCS caused by benign disease, in patients with long
life expectancy, the venous graft presents favorable long-term results.1
