Transposition of inferior vena cava  

International Nuclear Information System (INIS)

An incidentally detected transposition of the inferior vena cava in patient with gall bladder carcinoma is reported with discussion of findings of CT scan and review of anomalies of the inferior vena cava. Since anomalous vena cava may simulate any other abnormality such as metastatic disease, it is very important to know anomaly of the vena cava with understanding of its embryological background.

Vena cava replacement for malignant disease: is there a role?  

Science.gov (United States)

Resection and graft replacement of the vena cava for malignant disease is rarely performed, often because of the advanced tumor stage. Since August 1987 we have selectively performed caval replacement in conjunction with tumor resection in 11 patients. Three patients had superior vena cava reconstruction (SVCR) and eight had inferior vena cava replacement (IVCR). There were six males and five females whose mean age was 59.3 years (range 24 to 75 years). Two patients, each with superior vena cava obstruction, presented with symptoms from venous compression. Malignancies involving the superior vena cava were thyroid carcinoma in two patients and lymphoma in one. Cancers requiring IVCR were leiomyosarcoma in three patients, cholangiocarcinoma in two, and malignant fibrous histiocytoma, hepatocellular carcinoma, and colon carcinoma metastatic to the liver in one each. All IVCRs and two SVCRs were performed with expanded polytetrafluoroethylene grafts. The remaining SVCR was constructed with spiral saphenous vein. Six IVCRs involved replacement of the retrohepatic inferior vena cava in conjunction with major liver resection. Mean intraoperative blood transfusions were 5.3 units (range 0 to 10 units). There were no operative deaths. Complications occurred in four patients and included postoperative bleeding in two, myocardial infarction in one, and wound infection in one. There were no perioperative graft occlusions, but one patient developed graft occlusion 2 months after SVCR. All IVCR grafts have remained patent (mean follow-up of 8.8 months). Two patients with SVCRs have died from recurrent cancer at 3.2 and 3.4 years postoperatively. Six patients with IVCRs have developed tumor recurrence either locally (n = 1), at a distant site (n = 2), or both (n = 3). Importantly, eight of nine survivors have an excellent performance status. We conclude that vena cava reconstruction for malignancy can be performed safely, has few graft-related complications, and in some patients may offer the only possibility for tumor control.

Quality Assurance Guidelines for Superior Vena Cava Stenting in Malignant Disease  

International Nuclear Information System (INIS)

Superior vena cava stenting for the treatment of malignant superior vena cava obstruction is now well established. It offers simple, rapid, and safe palliation of a distressing and potentially fatal complication of mediastinal malignant disease and compares very favorably with standard therapies such as chemotherapy and radiotherapy. The following are quality assurance guidelines for superior vena cava stenting

The superior vena cava syndrome caused by malignant disease  

International Nuclear Information System (INIS)

Objective: The superior vena cava (SVC) obstruction by malignant diseases is either by direct invasion and compression or by tumour thrombus of the SVC. Whatever is its cause, obstruction of the SVC causes elevated pressure in the veins draining into the SVC and increased or reversed blood flow through collateral vessels. Severity of the syndrome depends on the collateral vascular system development. Therefore, imaging of the collateral veins with variable location and connection is important in determining the extension and management of the disease. Our aims are to describe collateral vessels of the superior vena cava syndrome (SVCS) related with the malignant diseases and to assess the ability of multi-detector row CT with multiplanar and 3D volume rendering techniques in determining and describing collateral circulations. Materials and methods: We present CT angiography findings of seven patients with small cell carcinoma of the lung (n = 2), squamous cell carcinoma of the lung (n = 3), Hodgkin disease of the thorax (n = 1), and squamous cell carcinoma of the oesophagus (n = 1). The patients received contrast-enhanced CT scans of the chest and abdomen on a multi-detector row CT during breath holding at suspended inspiration. Results: CT images revealed the cause and level of the SVC obstruction in all patients with axial and multiplanar reconstructed images. The SVC showed total obstruction in five patients and partial obstruction in two patients. The most common experienced collateral vessels were azygos vein (6), intercostal veins (6), mediastinal veins (6), paravertebral veins (5), hemiazygos vein (5), thoracoepigastric vein (5), internal mammary vein (5), thoracoacromioclavicular venous plexus (5), and anterior chest wall veins (5). While one case showed the portal-systemic shunt, V. cordis media and sinus coronarius with phrenic veins were enlarged in two cases, and the left adrenal vein was enlarged in a patient. In one case, the azygos vein with reversed blood flow was drained into both inferior vena cava and hemiazygos vein with the left renal vein. Conclusion: Multi-detector row CT with multiplanar and 3D imaging is an effective tool in evaluation of the SVCS and has a greater advantage than the other imaging techniques. 3D volume rendering is a useful technique in determining and describing collateral circulations in addition to the primary disease process

Vena cava tumor  

Directory of Open Access Journals (Sweden)

Full Text Available Vena cava tumor is a rare tumor and its surgical procedure is unique. A women patient, 55 years old, referred to our hospital becouse of intraabdominal mass. After preoperative preperation, the patient was operated for vena cava tumor. Total tumor excision and partially vena cava resection were performed and vena cava was repaired with synthetic vasculer graft patch. In pathological examination of mass, spindle cell sarcomatous malignant tumor was detected and it was interpreted as moderately differentiated leiyomyosarcoma. A rare clinical condition of this case was discussed together with literature.

[Massive inferior vena cava thrombosis in a patient with autosomal dominant polycystic hepatorenal disease].  

Science.gov (United States)

We report a 68-year-old man with autosomal dominant polycystic kidney disease, who developed multiple venous thromboses (inferior vena cava, left renal vein and iliofemoral veins) caused by local compression of the intrahepatic inferior vena cava by hepatic cysts. To our knowledge this is the first reported case of inferior vena cava thrombosis caused by hepatic cysts compression. Doppler ultrasound, computed tomography, and magnetic resonance imaging were effective in documenting the venous thromboses and the underlying lesions non-invasively. Long-term anticoagulation was an efficient and safe treatment. PMID:11987689

Vena cava filter; Vena-cava-Filter  

Energy Technology Data Exchange (ETDEWEB)

Fulminant pulmonary embolism is one of the major causes of death in the Western World. In most cases, deep leg and pelvic venous thrombosis are the cause. If an anticoagulant/thrombotic therapy is no longer possible or ineffective, a vena cava filter implant may be indicated if an embolism is threatening. Implantation of the filter is a simple and safe intervention. Nevertheless, it is necessary to take into consideration that the data base for determining the indications for this treatment are very limited. Currently, a reduction in the risk of thromboembolism with the use of filters of about 30%, of recurrences of almost 5% and fatal pulmonary embolism of 1% has been reported, with a risk of up to 20% of filter induced vena cava thrombosis. (orig.) [German] Die fulminante Lungenembolie zaehlt zu den Haupttodesursachen in der westlichen Welt. In der Mehrzahl der Faelle sind tiefe Bein- und Beckenvenenthrombosen ursaechlich verantwortlich. Ist eine antikoagulative/-thrombotische Therapie nicht (mehr) moeglich oder unwirksam, kann bei drohender Emboliegefahr die Vena-cava-Filterimplantation indiziert sein. Die Filterimplantation ist eine einfache und sehr sichere Intervention. Dennoch muss bei der Indikationsstellung beruecksichtigt werden, dass die Datenlage zur Wirksamkeit sehr limitiert ist. So wird aktuell ueber eine Reduktion des Thrombembolierisikos um 30% bei Embolierezidiven von knapp 5% und fatalen Lungenembolien von 1% unter Filterprophylaxe berichtet, bei einem Risiko von bis zu 20% fuer die filterinduzierte Vena-cava-Thrombose.

Superior vena cava syndrome secondary to thyroid cancer  

Digital Repository Infrastructure Vision for European Research (DRIVER)

It is uncommon for thyroid cancer to present with superior vena cava syndrome. Obstruction of superior vena cava can develop as a result of intrinsic and extrinsic spread of the thyroid cancer. The usual presentation of this disease entity is a neck mass with symptoms and signs suggestive of superior vena cava obstruction. Superior vena cava obstruction is commonly caused by lung cancer and lymphoma. However, thyroid cancer can cause superior vena cava obstruction by downward tumour spread in...

Persistent left superior vena cava with absent right superior vena cava: image findings  

International Nuclear Information System (INIS)

Persistent left superior vena cava absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the coronary sinus. We report the case of a patient with a persistent left superior vena cava and absence of right superior vena cava identified by chance during a chest radiograph and computed tomography examination for investigation of chronic pulmonary obstructive disease. The patient had no congenital heart disease and the blood from the right side was drained by the persistent left superior vena cava into the right atrium through the coronary sinus. (author)

Absence of right superior vena cava and persistence of left superior vena cava in fetus: Presenting two cases.  

Directory of Open Access Journals (Sweden)

Full Text Available Persistent Left Superior Vena Cava is the most common congenital vascular anomaly. In the vast majority of cases its persistence coincides with thepresence of the right superior vena cava. The absence of the latter with persistent left superior vena cava is a rare variant. We describe the ultrasonographicsigns that identify this rare malformation on fetus. The study was conducted in two pregnant women referred to the national reference center ofcongenital heart disease, showing a left superior vena cava draining into a dilated coronary sinus and the absence of right superior vena cava. Thepresence of a Persistent Left Superior Vena Cava with the absence of a Right Superior Vena Cava is a rare variant of systemic venous return that canbe diagnosed prenatally.

Deep venous thrombosis and inferior vena cava agenesis causing double crush sciatic neuropathy in Behçet's disease.  

Science.gov (United States)

We report here the case of a 18-year-old young man with Behçet's disease who had suffered deep venous thrombosis of the right femoral and popliteal veins. Consequently, right sciatic nerve injury, drop foot and tightness of the achilles tendon also ensued. The clinical scenario was further challenged by demonstration of the agenetic inferior vena cava and epidural vein dilatations compressing the lumbar nerve roots. To the best notice of the authors, this is the first patient encompassing all these complications in the literature concerning Behçet's disease. PMID:18848486

Fibrosing mediastinitis and thrombosis of superior vena cava associated with Behcet's disease  

Energy Technology Data Exchange (ETDEWEB)

We present CT, MRI and venography findings in 13-year boy with mediastinal fibrosis and superior vena cava (SVC) thrombosis associated with Behcet's disease. Fibrosing mediastinitis is an excessive fibrotic reaction that occurs in the mediastinum and may lead to compression of mediastinal structures (especially vascular). This condition is usually idiopathic, though many (and perhaps most) cases in the USA are thought to be caused by an abnormal immunologic response to Histoplasma capsulatum infection. SVC syndrome secondary to extrinsic compression by mediastinal fibrosis combined with Behcet's disease has rarely been described. Radiological investigations of this syndrome are necessary to avoid a useless anticoagulant therapy.

Antiphospholipid Antibody Syndrome Associated with Graves' Disease Presenting As Inferior Vena Cava Thrombosis with Bilateral Lower Limb DVT.  

Science.gov (United States)

We report a case of a 60-year-old lady who presented with bilateral lower limb swelling and a thyroid swelling with clinical features consistent with thyrotoxicosis. Investigations revealed the presence of a thrombus in bilateral external, internal iliac veins, and inferior vena cava extending up to its infrahepatic part. Hormone profile and radioiodine uptake scan confirmed the diagnosis of Graves' disease. Further workup revealed the presence of antiphospholipid antibodies (confirmed after a repeat test at 12 weeks). The patient was treated with antithyroid drugs and anticoagulants. The patient improved with normalization of thyroid function and partial recanalization of the infrahepatic part of inferior vena cava. Hyperthyroidism has been implicated as a potential hypercoagulable state; however, the association of Graves' disease with antiphospholipid antibody syndrome is limited to isolated case reports. This case highlights a new mechanism underlying hypercoagulability associated with Graves' disease. PMID:24812529

Roentgenologic appearance of left-sided inferior vena cava  

International Nuclear Information System (INIS)

2 Cases of left-sided inferior vena cava, and 2 cases of left-sided inferior vena cava with azygos and hemiazygos continuation were evaluated with computed tomography and other roentgenologic procedures and discussed thier clinical and radiological significance. Left-sided inferior vena cava with azygos (hemiazygos) continuation is often associated with cyanotic or acyanotic congenital heart disease and abnormalities of cardiovascular position, abdominal situs and polysplenia. But, single left-sided inferior vena cavas have little tendency having associated anomalies. Both venous anomalies also shuld be embryologically differentiated, namely, failure of development of the lower portion of the supracardinal veins results in infrahepatic interruption of inferior vena cava with azygos continuation, persistence of the left cardinal system and atrophy of the right system lead to the left-side inferior vena cava. Knowledge of inferior vena cava anomalies is important to the radiologist in order to differentiate between venous anomalies and an enlarged lymph nodes in a patient with malignant tumor. (author)

Left superior vena cava: revisited.  

Science.gov (United States)

The persistence of a left-sided superior vena cava is the most common variant of systemic venous drainage. Increased utility of cardiac imaging, in particular cross-sectional techniques such as computed tomography and magnetic resonance (MR), will result in increased detection of the anomaly and its variants. Whilst in the typical form it is often haemodynamically insignificant, its discovery may have clinical significance nonetheless, and its mimics require exclusion. During cardiac development the anomaly results from a failure of the left anterior cardinal vein to obliterate. Recognized anatomical variants include the absence of the right superior vena cava and of an innominate bridging vein. Typical drainage is to the coronary sinus, dilatation of which may be the first hint to the anomaly. Clinical implications with respect to vascular access and arrhythmia are well described. A significant minority drain into the left atrium, potentially creating a haemodynamically significant lesion. Additionally, differentiation from anomalous left upper pulmonary venous drainage via a vertical vein is mandatory. A newly discovered variant runs an intra-atrial course with subsequent typical drainage, and if not recognized as such, may be confused with a left atrial mass. The use of 3D contrast-enhanced MR venography has proven extremely helpful in characterizing anomalous vasculature, and we demonstrate how such techniques can help delineate the anomaly and differentiate from its mimics.

Superior vena cava syndrome in children  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Superior vena cava syndrome (SVCS) is rare in childhood. 18 cases of SVCS were seen in children ranging from 3–14 years with a mean age of 8.8 years. There were 15 males and 3 female children. Diagnosis could be confirmed in 17 cases as one child succumbed to severe respiratory distress without a definitive diagnosis. The commonest cause of SVCS was lymphoma. Non-Hodgkin’s lymphoma (NHL) was more common than Hodgkin’s disease. In two cases the final diagnosis was tuberculosis of mediast...

Therapeutic approach to "downhill" esophageal varices bleeding due to superior vena cava syndrome in Behcet's disease: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background One of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time. Case presentation We report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur. Conclusion Band ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

Leiomyosarcoma of inferior vena cava.  

Science.gov (United States)

Malignancy arising from the blood vessels is a very rare finding in daily clinical practice. In addition, the finding can often be misdiagnosed and ill-treated. These tumors usually go unnoticed unless it has metastasized to distant tissues. Among these rare tumors, leiomyosarcoma is the most common. It mostly arises in the inferior vena cava (IVC). Clinical signs and symptoms are very vague. Usually it is often misdiagnosed as an abscess cavity in the liver or primary hepatic malignancy (when present at level II) or as a thrombus in the IVC. Radiological investigations are the key to proper diagnosis. Depending upon the exact location, further treatment options vary. Generally, it is believed that level II and level III tumors are amenable to surgery followed by chemo or radiotherapy. We present a rare case of leiomyosarcoma of IVC at level II being diagnosed with proper radiological investigations and its management with further stress on offering chemo-radiotherapy after its surgical removal as compared to only surgery performed earlier. This case report will throw some light on the proper management of such rare tumors in terms of their exact diagnosis and treatment in order to prolong patient survival. PMID:22120864

Vena Cava ?nvasion by Adrenal Leiomyosarcoma  

Science.gov (United States)

Primary adrenal mesenchymal tumors are extremely rare. These tumors are hard to diagnose, and similar to certain adrenal tumors, as they do not produce hormones, and they can only manifest themselves when the tumor reaches an advanced size. These tumors are generally detected incidentally. This study reports a rare case of primary leiomyosarcoma of the right adrenal gland with vena cava invasion, in a 70-year-old woman who presented with right flank pain. Computerized tomography showed an adrenal mass with a diameter of 78 mm, which exerted pressure on the vena cava inferior. The invasive part was excised by using adrenalectomy and cavatomy. Tumor invasion was determined on the wall of the vena cava. Histopathological examination on 10× magnification showed 8-10 mitotic events. Immunohistochemical staining showed that the cells were SMA (+), desmin (+), cytokeratin (-), and Bcl-2 (-). The Ki67 proliferation index was 70%. Widespread metastasis developed six months after the adrenalectomy.

Inferior vena cava tumors - diagnostic difficulties  

International Nuclear Information System (INIS)

We present a patient with a diagnosis of tumor within the vena cava inferior, which was detected during screening abdominal ultrasound examination. Repeated abdominal ultrasound examination, CT and MRI were performed in order to make diagnosis more precise. Imaging revealed the tumor within the lumen of dilated inferior vena cava, which was significantly obstructed by tumor masses. Final diagnosis was made on the basis of postoperative histopathological and immunohistochemical findings, which confirmed the renal cell carcinoma within the inferior vena cava, without any delectable lesion in kidneys. Despite imaging of retroperitoneal tumors allows accurate assessment of morphology and extent of tumor masses, it is often required to perform surgery and histopathological examination to state the final diagnosis.

Leiomyosarcoma of the inferior vena cava.  

Science.gov (United States)

The thirty-second case of leiomyosarcoma of the inferior vena cava and the twelfth resectable patient in the series is presented. A review of the literature demonstrates a marked female preponderance (5 to 1). The most common presenting symptom is right abdominal pain and a palpable mass. The different surgical problems generated by the involved segment of the cava are discussed. Noteworthy is the high incidence of Budd-Chiari syndrome owing to hepatic vein obstruction with involvement of the upper third of the cava in the postmortem cases. An argument is developed for debulking the tumor for palliation when it is not completely removable. PMID:95619

Complex malformation of the inferior vena cava.  

Science.gov (United States)

Malformations of the inferior vena cava (IVC) are rare presentations, exceptional in children, and are usually asymptomatic.They are caused by disturbances in the embryological formation of the venous system or can develop as a result of perinatal venous thrombosis with secondary impairment of the venous development. We report the case of a 14 year old boy,admitted for pediatric evaluation before undergoing plastic surgery in order to remove superficial varicose veins of the lower abdomen. The patient presents with inequality in circumference and length of the legs. Laboratory investigations are normal and the abdominal ultrasound describes hypoplasia of the retrohepatic segment of the inferior vena cava. The diagnosis of complex malformation of the abdominal deep venous system (retrohepatic vena cava atresia, cavo-caval anastomosis through azygos veins, abnormal formation of the inferior vena cava with the absence of the left iliac vein) was established through a CT angiography. The presence of abdominal varicose dilations should indicate the necessity to closely look for malformations of the portal and/or caval venous systems. PMID:24742422

Endovascular treatment of superior vena cava syndrome  

DEFF Research Database (Denmark)

Abstract AIM: The aim of this study was to report our experience with palliative stent treatment of superior vena cava syndrome. METHODS: Between January 2008 and December 2009, 30 patients (mean age 60.7 years) were treated with stents because of stenosed superior vena cava. All patients presented clinically with superior vena cava syndrome and according caval stenosis confirmed by computed tomography. The causes of stenoses were non-small cell carcinoma in 22 patients and small cell carcinoma in 8 patients. RESULTS: In all patients the stents were placed as intended in all patients there was an immediate clinical improvement with considerable reduction in the edema of upper extremities and head. There was, however, continous dyspnea in five patients (17%) and two patients (7%) had persistent visible collateral venous circulations on the upper chest. There were no stent associated complications. All patients were followed clinically till death and the median follow-up period was 2.8 months (15-420 days). During follow-up three cases of stent thrombosis (one complete and two partial thrombosis) were observed. CONCLUSION: Palliative care with stent implantation for superior vena cava syndrome is a minimal invasive and safe procedure with good clinical effect giving the patients a significant better quality of their residual life.

Tratamento da síndrome da veia cava superior Treatment of superior vena cava syndrome  

Directory of Open Access Journals (Sweden)

Full Text Available A veia cava superior é formada pela união das duas veias inominadas, direita e esquerda, e localiza-se no mediastino médio, à direita da artéria aorta e anteriormente à traquéia. A síndrome da veia cava superior representa um conjunto de sinais (dilatação das veias do pescoço, pletora facial, edema de membros superiores, cianose e sintomas (cefaléia, dispnéia, tosse, edema de membro superior, ortopnéia e disfagia decorrentes da obstrução do fluxo sanguíneo através da veia cava superior em direção ao átrio direito. A obstrução pode ser causada por compressão extrínseca, invasão tumoral, trombose ou por dificuldade do retorno venoso ao coração secundária a doenças intra-atriais ou intraluminais. Aproximadamente 73% a 97% dos casos de síndrome da veia cava superior ocorrem durante a evolução de processos malignos intratorácicos. A maioria dos pacientes com a síndrome secundária a neoplasias malignas é tratada sem necessidade de cirurgia, através de radioterapia ou quimioterapia, ou através da colocação de stents endoluminais. Quando a síndrome é de etiologia benigna, o tratamento é feito através de medidas clínicas (anticoagulação, elevação da cabeça, etc. ou, em casos refratários, através de angioplastia, colocação de stents endoluminais e cirurgia.The superior vena cava is formed by the union of the right and left brachiocephalic veins. It is located in the middle mediastinum, to the right of the aorta and anterior to the trachea. Superior vena cava syndrome consists of a group of signs (dilation of the veins in the neck, facial swelling, edema of the upper limbs, and cyanosis and symptoms (headache, dyspnea, cough, orthopnea and dysphagia caused by the obstruction of blood flow through the superior vena cava to the right atrium. This obstruction can be caused by extrinsic compression, tumor invasion or thrombosis. Such obstruction may also occur as a result of insufficient venous return secondary to intra-atrial or intraluminal diseases. From 73% to 93% of all cases of superior vena cava syndrome occur during the development of an intrathoracic tumor. Most patients presenting superior vena cava syndrome secondary to malignant neoplasms are treated without surgery, through radiotherapy, chemotherapy or the use of intraluminal stents. When the etiology of superior vena cava syndrome is benign, it can be treated with clinical measures (anticoagulation, raising the head, etc. or, in refractory cases, with angioplasty, stents or surgery.

Superior vena cava syndrome caused by epitheloid hemangioma  

Directory of Open Access Journals (Sweden)

Full Text Available Aim. A case is presented of the surgical treatment of epitheloid hemangioma as a rare cause of superior vena cava syndrome. Case report. A 53-year old woman was admitted to the clinic with the symptoms and signs of superior vena cava syndrome. After clinical evaluation and diagnostic tests, she was operated on through median sternotomy, and the desobliteration of the superior vena cava through longitudinal ca votomy was done. After the desobliteration by the removal of benign tumor from its cavity, vena cava was reconstructed with the continuous prolen suture. Pathohistologicaly, there was the evidence of epitheloid hemangioma that made the subtotal obliteration of the vena cava superior by its expansive growing at the entry in the right atrium. Postoperatively, there was a complete disappearance of the symptoms and signs of superior vena cava syndrome. After an uneventful recovery, the patient was discharged from the hospital.

Superior Vena Cava Thrombosis in a Case of Lung Adenocarcinoma  

Directory of Open Access Journals (Sweden)

Full Text Available Superior vena cava syndrome is a common presentation of bronchogenic carcinoma. The mechanism of obstruction is by compression of superior vena cava by the bronchogenic tumor itself or enlarged mediastinal lymph nodes. However obstruction due to intravascular thrombosis is extremely uncommon. Here, we report a rare case of a 65-year-old male smoker who presented with superior vena cava syndrome and bilateral pleural and pericardial effusion with thrombotic occlusion of the superior vena cava in adenocarcinoma of the lung. He was given chemotherapy with carboplatin and gemcitabine with anticoagulant therapy.

Computed tomography of superior vena cava obstruction.  

Science.gov (United States)

Which imaging procedure is best for the diagnosis of the superior vena cava (SVC) syndrome is subject to considerable debate. Available imaging procedures include the plain chest film, SVC phlebography, scintiangiography, digital phlebography, CT digital phlebography, and CT. In our experience the combined technique of contrast enhanced CT axial images, followed by a CT digital phlebogram, is the most informative, cost-effective, and least invasive method available.

Cardiac metastasis in renal cell carcinoma without vena cava or atrial involvement: an unusual presentation of metastatic disease  

Directory of Open Access Journals (Sweden)

Full Text Available Cardiac metastasis in renal cell carcinoma is a very rare entity, with only a few previously reported cases. In this series, we report two cases of ventricular metastases from renal cell carcinoma without vena cava or right atrial involvement. The first case involves an initially isolated inoperable metastasis to the left ventricle, which was treated with systemic targeted therapy with favorable local response. Our second case illustrates a patient with an isolated cardiac metastasis in the interventricular septum with extension into the right ventricle, which has also remained stable in size on systemic targeted therapy. Although anti-angiogenic agents such as tyrosine kinase inhibitors have transformed the treatment of metastatic renal cell carcinoma in recent years, their efficacy and safety in treating patients with metastatic disease in highly vascular organs such as the heart are currently unknown, with no prior reports on this topic. We describe our novel management of these unique cases and discuss the current medical and surgical approaches to treating cardiac metastases from renal cell carcinoma.

CT appearances of anomalous inferior vena cava. Azygos continuation  

International Nuclear Information System (INIS)

The azygos continuation is a rare variation of the inferior vena cava (IVC), usually associated with cardiac anomalies. We report CT in two female patients with no cardiac disease. One had no further visceral abnormities, while the other had polysplenia agenesis of the left lobe and a hypertrophic right lobe of the liver. This complex of anomalies has been demonstrated for the first time by imaging. Our cases show the variation of anomalies associated with azygos continuation. When planing therapeutic procedures (for example cava filtration). These anomalies are relevant. CT is sufficient for their demonstration and in most cases there is no need for confirmation by invasive methods. (orig.)

Tratamiento endovascular del síndrome de vena cava superior Endovascular treatment of superior vena cava syndrome  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Superior vena cava syndrome (SVCS is caused by the obstruction of venous drainage from the upper portion of the body. Common clinical findings are headache and cervical, facial and upper limb edema. Occasionally, clouding of consciousness appears. Aim: to report our experience with endovascular treatment of SVCS. Material and methods: Retrospective review of all patients with SVCS subjected to endovascular treatment between 1999 and 2005. Results: Eight patients were treated, all of them with malignancies. Six had a benign obstruction due to the presence of a chemotherapy catheter located in the superior vena cava, one had obstruction secondary to radiation therapy and one a tumor compression of the superior vena cava. Two patients underwent thrombolytic therapy. Angioplasty and stenting was performed in all patients. The chemotherapy catheter was removed to all patients and installed again in one. One patient had a hemothorax secondary to a simultaneous needle lung biopsy under video thoracoscopy. No patient died in relation to the procedure. Congestive signs and symptoms subsided in all patients within 24 hours after the procedure. During follow up, only one patient had symptoms related to vena cava obstruction and three died due to their malignant tumor. Conclusions: Endovascular treatment of SVCS has a low rate of complications and provides immediate and mid-term symptom relief

Persistent left superior vena cava and pacemaker implantation  

Directory of Open Access Journals (Sweden)

Full Text Available Our study group read with interest the paper from Vijayvergiya et al describing the implantation of an implantable cardioverter-defibrillator lead in the presence of the persistence of the left superior vena cava. The issue of the identification a persistent left superior vena cava is of paramount importance in interventional cardiology, being the most common venous anomaly of the thoracic distribution, and because it may create some problem to any physician while performing a pacemaker lead implantation. In our letter we underscore the specific issues related to pacemaker implantation while encountering a persistent left superior vena cava (and maybe the absence of the right vena cava and the workup that should be performed to obtain the preoperative diagnosis of the venous anomaly. More specifically, we consider avoiding any kind of defibrillator lead implantation through the coronary sinus for safety issues, and underscore the straightforward transthoracic ultrasound approach to identify the left superior vena cava.

In Vitro Studies of Temporary Vena Cava Filters  

International Nuclear Information System (INIS)

Purpose: To evaluate the clot trapping capacity of different temporary vena cava filters in a vena cava model. Methods: A vena cava flow model was built using PVC tubing, a hemodialysis membrane and a pulsatile pump. Blood was imitated by a Dextran 40 solution. Five different temporary vena cava filters and two prototypes were tested using human thrombi. The mechanism of clot capture was observed. Results: Decreasing rank order according to decreasing percentage of clots captured for the 21-mm diameter vena cava model was Cook (C) > Angiocor (A) > Cordis (CD) > Antheor (TF-6) > DIL for thrombi with a diameter of 3 mm and A > C > CD > TF-6 > DIL for 5-mm thrombi. In a cava with diameter of 28 mm, decreasing rank order was C > CD = A > TF-6 > DIL and C > CD = A > DIL > TF-6 for 3- and 5-mm thrombi, respectively. Two new prototypes, the TF-8 and TF-10 filters, achieved better results than the TF-6 filter and were in most conditions comparable to the A and CD filters. In most cases, thrombi were trapped between filter and cava wall. Conclusion: The vena cava flow model demonstrates significant differences in rates of clot capture (range 22%-98%) depending on cava diameter, thrombus size, and filter type

The leiomyosarcoma of the vena cava inferior  

International Nuclear Information System (INIS)

The leiomyosarcoma of the Vena cava inferior is a mesenchymal tumor originating from the smooth muscle fibers of the vascular wall. This tumor is usually slow-growing and of expansive growth. Prior to the sonographic and computer-tomographic era the tumor was usually only discovered during autopsy or surgery without any preoperative suspicion. Today, the most efficient imaging methods for exact localization, delineation or relation to the vascular lumen and local extent are sonography and computer tomography. Caudal cavography is called upon for preoperative demonstration of the venous collateral circulation and thrombotic vascular occlusion. (orig.)

Radionuclide venography in the evaluation of superior vena cava syndrome  

International Nuclear Information System (INIS)

Isotopic phlebography with Tc-99m-labeled microspheres was performed in 55 patients, 22 of whom presented with superior vena cava syndrome. The localization of the venous obstruction was visualized in each case, along with associated collateral views. Moreover, the transit times at different levels were markedly increased. In 11 patients, isotopic phlebography was repeated following treatment. Improvement, when it occurred, was largely due to diminished obstruction of the superior vena cava rather than to increased collateral supply. Therefore, isotopic phlebography of the upper extremities is a useful tool for the diagnosis of superior vena cava syndrome and for the evaluation of response to treatment

Right superior vena cava draining into the left atrium  

Energy Technology Data Exchange (ETDEWEB)

The right superior vena cava draining into the left atrium is a rare malformation causing cyanosis and clubbing in patients in whom no other signs of congenital heart defect are present. Diagnosis may be difficult as cyanosis may be mild and the anomaly is not always easily detectable by echocardiography. For this reason we report a 13-month-old male in whom we confirmed the clinical and echocardiographic suspicion of anomalous drainage of the right superior vena cava using multidetector CT. This allowed successful surgical reconnection of the right superior vena cava to the right atrium. (orig.)

Radiological evaluation of inferior vena cava obstruction: pictorial essay  

International Nuclear Information System (INIS)

The clinical diagnosis of inferior vena cava (IVC) obstruction is often difficult, since patients may present with a multitude of signs and symptoms. The clinical manifestations depend on several factors: the underlying cause, the level of obstruction, the adequacy of collateral circulation, the presence of intercurrent disease, and the organ system involved. Although the most common clinical manifestations are deep venous thrombosis in the legs, abdominal pain, low back pain, loin pain and hematuria, patients may present with unusual and varied pathologic conditions. IVC obstruction may resemble or be associated with such conditions as congestive cardiac failure, cirrhosis of the liver or renal disease. (author)

Terapia endovascular en el sindrome de vena cava superior: caso clínico Endovascular treatment of superior vena cava syndrome: Report of one case  

Directory of Open Access Journals (Sweden)

Full Text Available The treatment of superior vena cava syndrome is usually oriented to the underlying cause, that can be too slow in emergency cases. We report a 49 years old woman with a multiple myeloma that was admitted due to a superior vena cava syndrome caused by a central venous catheter used for chemotherapy for 20 weeks. She was successfully treated with thrombolysis, angioplasty and stent placement. The patient died 7 months later due to the underlying disease. Long term catheters are the responsible for 20 to 30% of superior vena cava syndromes. Endovascular treatment of the syndrome is successful in 60 to 100% of cases with a symptomatic relapse in 4 to 45% of patients. (Rev Méd Chile 2001; 129: 421-6

Congenital anomalies of the inferior vena cava  

International Nuclear Information System (INIS)

Congenital anomalies of the inferior vena cava (IVC) and its tributaries are increasingly recognized in asymptomatic patients due to the more frequent use of cross-sectional imaging and computed tomography (CT) in particular. IVC development is a complex process involving formation of anastomoses between three pairs of embryonic veins in the 4th to 8th week of gestation. Various permutations occur in the basic venous plan of the abdomen and pelvis resulting in variants such as isolated left IVC, double IVC, and retroaortic left renal vein. The majority of these anomalies are asymptomatic but occasionally present clinically with thromboembolic complications. However, awareness of their existence is important to avoid important diagnostic pitfalls and in preoperative surgical and interventional radiological planning.

Radiation therapy for superior vena cava syndrome  

International Nuclear Information System (INIS)

We studied the effect of such variables as the symptom improvement rate, survival and prognostic factors on the treatment results of radiation therapy for Superior Vena Cava Syndrome (SVCS). From 1988 to 2003, seventy two patients with SVCS were treated with radiation therapy at the Department of Radiation Oncology, Keimyung University Dongsan Medical Center. The patients' ages ranged from 10 to 83 years old with the median age being 61, and sixty four patients were male. For the causes of the SVCS, 64 patients had lung cancer, four had metastatic lung cancer, two had malignant lymphoma and two had thymoma. The radiotherapy was delivered with 6-MV X-ray and all patients received above 900 cGy up to 6,600 cGy, with the median dose being 4,000 cGy. The follow-up periods were from 1 to 180 months with a median of 5.6 months. The main clinical manifestations were dyspnea (84.7%), facial edema (81.9%), arm edema (22.2%), neck vein distension (25%), hoarseness (12.5%) and facial plethora (5.6%). Eighty percent of patients achieved excellent to good symptom improvement and 19.4% experienced minimal improvement. The median survival period was 5.1 months, and overall survival rates were 17.7% at 2 years (2YOS) and 14.8% at five years (5YOS) for all the patients. The median survival period, the two and five year disease free survival rates were 4.3 months, 16.7% and 13.4% for the lung cancer patients, respectively. The total tumor dose was a statistically significant survival factor on the univariate analysis for the patients with lung cancer (2YSR; > 30 Gy, 25.6%, ? 30 Gy 6.7%, ? 0.05). Radiation therapy for the patients with SVCS due to malignancy could be an effective treatment. We considered that radiation therapy above 30 Gy of the total tumor dose may improve survival for SVCS due to lung cancer

Our objective is to evaluate the incidence, the clinical findings and the operative approach to IVC injuries. METHODS: We retrospectively studied 76 patients with IVC injuries treated in two Emergency Hospitals of Manaus, AM, Brazil, from January 1997 to July 2002. Mechanisms of injuries, mortality, hemodynamic status, penetrating abdominal trauma index (PATI, intraoperative findings and surgical approach were among assessed data. RESULTS: Fourty-nine patients (65% had stab wounds, 26 (34% gunshot wounds, and one had blunt abdominal trauma. Fourty-one (54% patients survived. Almost all patients entered the emergency room awake, although 40% were hypotensive (systolic blood pressure < 70 mmHg, and the penetrating abdominal trauma index average was above 40. At laparotomy, active retroperitoneal bleeding or an expanding retroperitoneal hematoma were detected in all cases. Caval injury was retro-hepatic in 21 patients, and infrahepatic in the other 55. The prevailing surgical approach was lateral repair in 65 patients. Atrial-caval shunting was tried in six patients, with only three survivals. CONCLUSIONS: We concluded that IVC injury remains a highly lethal injury and there is a close relationship with urban violence. This study emphasizes that successful outcome depends on prompt volume restoration, avoidance of hypothermia and a stratified selective surgical approach.

Neuroimaging findings in neonates and infants from superior vena cava obstruction after cardiac operation  

Energy Technology Data Exchange (ETDEWEB)

Extraventricular obstructive hydrocephalus may develop after superior vena cava obstruction, an uncommon complication after cardiac surgery.Objective. To describe the neuroimaging findings in neonates and infants with superior vena cava thrombosis after cardiac surgery for congenital heart disease.Materials and methods. Between 1993 and 2001, 333 neonates and infants in our hospital underwent cardiac surgery, of whom 13 (3.9%) subsequently acquired superior vena cava syndrome. Eleven of these 13 children (7 boys, 4 girls) were evaluated by head ultrasound and computed tomography scans.Results. One child had normal findings on head ultrasound, and 10 children had extraventricular obstructive hydrocephalus (EVOH). In 6 children, aggravation of the hydrocephalus was noted up to 11.4 months after cardiac surgery; in 3 of them, the hydrocephalus was shunted to the peritoneum. One child had thrombosis of the dural sinuses, and 1 had hemorrhagic infarction. Two children died during follow-up.Conclusion. EVOH is a common complication of superior vena cava thrombosis, and head ultrasound should be performed in all neonates and infants with superior vena cava thrombosis after cardiac surgery. Long-term follow-up is needed, as the hydrocephalus may worsen even months after surgery. (orig.)

Concomitant pulmonary arteriovenous and inferior vena cava malformations  

International Nuclear Information System (INIS)

A case of pulmonary arterio-venous malformation (AVM) presenting with dyspnoea diagnosed by computer tomography (CT) and pulmonary angiography is reported. Venous anomalies in the form of agenesis of the iliac veins and the inferior vena cava (IVC), were discovered through femoral venograms performed after technical difficulties were encountered at pulmonary angiography performed via the femoral route. These venous anomalies co-existed with normal but dilated azygos and hemiazygos systems, and with the azygos appearing as a right hilar mass lesion which showed the 'candy cane sign' on the lateral view on venography. A dilated varix at the confluence of the right renal vein and the IVC collaterals was also noted. This association of a pulmonary AVM and IVC agenesis has not been previously reported in the literature. The embryogenesis of the inferior vena cava and the azygos system is presented in an attempt to explain the rare association of these anomalies. The various techniques of diagnosing the disease entities, expecially by CT, are discussed. The rare co-existence of pulmonary AVM and the absence of the IVC is emphasized. (orig.)

Superior Vena Cava Syndrome Following Central Venous Cannulation  

Directory of Open Access Journals (Sweden)

Full Text Available Superior vena cava syndrome caused by blockage of the vein that carries blood from the head, neck, chest, and arms to the heart may occur due to various etiologies including thrombosis, occlusion and pressure on the superior vena cava. Foreign instruments in the vein, infections and also intimae injuries can lead to venacaval thrombosis . One of the most common causes of caval thrombosis is central venous catheterization for fluid administration and hemodialysis. This report presents an 8 years-old girl with chronic benign superior vena cava syndrome related to the long-term use of central venous catheters for hemodialysis. Treatment included resection of the obstructed segment and repair of the superior vena cava with an autologous pericardial patch.Reconstruction with an autologous pericardial patch without bypass of superior vena cava to right atrium is a safe and simple method but more importantly it is preferable and easier to prevent these events by simple nursing care in dialysis unit to secure the dialysis access.

Normal Inferior Vena Cava (IVC) of 15 cases were studies on CT with bolus injection in the foot vein.FWell dilated IVC were obtained on scan both at full-inspiration and full-expiration. As the normal findings of IVC, different opacification patterns which may be designate ''homogenous'', ''layered'' and ''pseudothrombus'' were obtained. The ''homogenous'' opacification was noted both at full-inspiration and full-expiration. In homogenous patterns as noted as ''layered'' and ''pseudothrombus'' were suspected to occur in the case of insufficient mixing of contrast agent with blood and/or insufficient amount of contrast agent. And both these patterns were observed in dilated IVC. The ''layered'' opacified IVC was shown on scan at full-inspiration at which respiratory phase the blood flow in IVC may decrease.FThe ''pseudothrombus'' pattern was generally noted at full-expiration at which the blood flow may increase.FAlthough bolus injection of contrast agent into foot vein is useful for evaluation of IVC, one shound be aware of normal opacification of IVC including ''pseudothrombus'' pattern.

Leiomyosarcoma of the inferior vena cava.  

Science.gov (United States)

The purpose of this article is to present the CT features in five cases of pathologically verified Inferior vena cava (IVC) leiomyosarcoma. In this retrospective analysis, we reviewed CT features in 5 cases of clinicopathologically confirmed IVC leiomyosarcoma with respect to its location (infra renal, trans renal, supra renal), its extent (with or without involvement of renal vein, hepatic IVC with or without involvement of hepatic vein, right atrial & extra caval extension) and pattern of enhancement. CT guided biopsy was performed in four patients while the last patient underwent successful resection of the tumor. Three male and two female patients (aged 45 to 72 years) were included in the study. Heterogeneously enhancing retroperitoneal mass involving IVC is the most common imaging feature. The intra and extra luminal extension was demonstrated excellently in all patients. IVC leiomyosarcoma is a rare neoplasm often presenting very late with non-specific symptoms. Cross sectional imaging establishes the exact location and extension and plays a vital role in determining the resectibility and planning the management. PMID:24784870

An echocardiographic measurement of superior vena cava to inferior vena cava distance in patientsdilated cardiomyopathy.  

Science.gov (United States)

In normal pediatric echocardiograms, the distance from the junction of superior vena cava (SVC) and right atrium to inferior vena cava (IVC) and right atrium is linearly related to height. We examine this relation in children listed for heart transplant with idiopathic dilated cardiomyopathy (IDC) compared with the previously defined normal distribution of SVC-IVC to improve matching of heart sizes. Measurements of SVC-IVC and left ventricular end-diastolic diameter in 55 pediatric patients with IDC were correlated with height, weight, and body surface area. Regression analyses were performed to find the best-fit equation and correlation coefficient. Generalized linear modeling compared SVC-IVC in patients with IDC with normal SVC-IVC values from 254 patients. There was a strong linear relation in patients with IDC between SVC-IVC and height (R2=0.84) and a logarithmic relation to weight (R2=0.80). Left ventricular end-diastolic diameter did not correlate with SVC-IVC or any other parameter. In 87% of patients with IDC, SVC-IVC was over 2 SDs above predicted normal values (mean z-score=4.3±2.1). In conclusion, predicted SVC-IVC in patients with IDC was different from published norms (p<0.001). SVC-IVC in pediatric patients with IDC, although linearly related to height, is consistently above normal values. PMID:24581921

Vena cava thrombosis after vena cava filter placement: Incidence and risk factors  

Directory of Open Access Journals (Sweden)

Full Text Available Background The objective of this study was to assess the clinical safety and efficacy of vena cava filter (VCF placement, with particular emphasis on the incidence and risk factors of inferior vena cava thrombosis (VCT after VCF placement. Methods Clinical data of patients with venous thromboembolism (VTE, with or without placement of VCF, were analyzed in a retrospective single-center audit of medical records from January 2005 to June 2009. The collected data included demographics, procedural details, filter type, indications, and complications. Results A total of 168 cases of VTE (82 with VCF; 86 without VCF were examined. Over a median follow-up of 24.2 months, VCT occurred in 18 of 82 patients with VCFs (11 males, 7 females, mean age 55.4 years. In 86 patients without VCFs, VCT occurred in only 6 individuals (4 males, 2 females during the study period. VCT was observed more frequently in patients fitted with VCFs than in those without VCFs (22% vs. 7.0%. Conclusions The incidence of VCT in patients with VTE after VCF implantation was 22% approximately. Anticoagulation therapy should be continued for all patients with VCF placement, unless there is a specific contraindication. Almost all instances of VCT in patients with VCF implants in our study occurred after stopping anticoagulation treatment. The use of VCFs is increasing, and more trials are needed to confirm their benefit and accurately assess their safety.

Persistent Left Superior Vena Cava with Absence of Right Superior Vena Cava.  

Directory of Open Access Journals (Sweden)

Full Text Available The variations on the venous system’s conformation are closely related with the embryological development, due to atrophy or persistency of embryological connections that this system establishes for its final formation. During a routine dissection of a heart-lung block of a male Caucasian cadaver (40 % formolized, at the Dissection Team of the Second Chair of Anatomy, School of Medicine, University of Buenos Aires, our team found a persistent left superior vena cava (PLSVC, with its right superior vena cava (RSVC missing. In addition, the PLSVC was draining to a dilated coronary sinus. Before the PLSVC drains, it receives the corresponding Acygos vein, which describes its journey above the left pulmonary root. It is essential for the specialist physician to be aware of the existence of this variation in order to address and resolve safely the procedure and the existing pathology of the patient, since, most of the time, this vascular anomaly is found incidentally in the context of a CT, echocardiogram, or during the placement of endocavitary catheters.

[Polysplenia with duplication of the inferior vena cava. Apropos of a case].  

Science.gov (United States)

A case of polysplenia fortuitously discovered in an adult by sonography, then studied by computed tomography and inferior vena cavography, is reported. In the absence of cardiac anomalies, the different elements of the syndrome are discussed: multiple spleens, abdominal heterotaxia and vascular malformations. The duplication of the inferior vena cava is exceptional in this disease. Its original characteristic is shown by the cavography and brought to its embryologic origin. PMID:3585859

Computed tomographic evaluation of the renal vein and inferior vena cava in renal cell carcinoma  

International Nuclear Information System (INIS)

Renal cell carcinoma not rarely invades the renal vein and inferior vena cava with formation of tumor thrombus. On the other hand, congenital anomalies of these venous channels are occasionally encountered. At the time of surgery of renal cell carcinoma, therefore, preoperative evaluation of the renal vein and inferior vena cava is desirable. In 22 cases of renal cell carcinoma treated at the Jikei University Hospital during 16 months period from Jan. 1979 to apr. 1980, the ranal vein and inferior vena cava were examined by computed tomography (CT). Intravenous tumor thrombus was diagnosed in 4, double inferior vena cava in one and retroaortic left renal vein in one. All these CT diagnosis were confirmed to be correct by surgery. Three of tumor thrombus cases showed involvement of inferior vena cava. CT findings included dilated vein in 4 and filling defect after contrast enhancement in 2. In double inferior vena cava, CT at the level of the upper pole of kidney showed the left inferior vena cava traversing in front of the aorta and conjoining the left inferior vena cava, CT at the level of renal vein the left renal vein draining into the left inferior vena cava and CT at the lower level two round inferior vena cava with the aorta between them. It was a diagnostically useful finding that the left inferior vena cava was markedly stained in CT after contrast enhancement jestas the aorta and the right inferior vena cava. In retroaortic left renal vein, CT showed the left renal vein running behind the aorta and draining into the inferior vena cava. Preoperative information on congenital anomalies of the renal vein and inferior vena cava or tumor thrombus and its extension are very important particularly for radical surgery to be conducted safely without postoperative complications. Computed tomography is quite useful in evaluation of morbid state of the renal vein and inferior vena cava. (author)

Displacements and complications of superior vena cava catheter  

International Nuclear Information System (INIS)

During a 16-months prospective study the frequency of displacements and complications of superior vena cava catheter has been investigated. The study showed, that the right jugular catheter has the lowest frequency of complications, and should be of primary choice. Pneumothoraces are rare with jugular vena catheters (0,05%), more frequently with subclavian catheters. Setting of superior vena catheter displacement in large veins is quite common. More important are catheter displacements in small veins, which are more frequent with jugular than with subclavian vena catheter (vena thoracica interna, vena pericardiacophrenica). Adequate X-ray control (high KV technic, sufficient amount of contrast medium) is necessary to recognize these complications. Correction of displaced catheter should be done under fluoroscopy. Serious complications s.e. tension pneumothorax and haematothorax are rare and should be treated surgically. In some cases non recognized extraversal catheterposition is followed by infusions into the pleural cavity or the mediastinum. (orig.)

Inferior vena cava endograft to control surgically inaccessible hemorrhage.  

Science.gov (United States)

Open surgical repair of retrohepatic inferior vena cava (IVC) injuries can be technically difficult, usually requiring extensive hepatic mobilization and associated with significant morbidity. We report a case of uncontrolled hemorrhage from the retrohepatic inferior vena cava (IVC), which occurred during attempted resection of a large retroperitoneal leiomyosarcoma, and was successfully managed using an endoluminal stent-graft. This case demonstrates that endoluminal grafts can be successfully applied to control life-threatening hemorrhage arising from lesions in the retrohepatic IVC that are otherwise extremely difficult or inaccessible to direct surgical repair.

Fatal Pericardial Tamponade After Superior Vena Cava Stenting  

International Nuclear Information System (INIS)

We discuss a fatal complication of percutaneous superior vena cava (SVC) self-expandable stent placement in a patient with superior vena cava syndrome (SVCS). The SVCS was caused by a malignant mediastinal mass with total occlusion of the SVC. Twenty-four hours after the procedure, the patient died of a hemopericardial tamponade. In the literature, only seven cases have been described with this life-threatening complication. Patients with a necrotic tumor mass are more likely to develop this complication. Knowledge of this complication may increase patient survival.

Hepatic and postrenal segment anomalies of inferior vena cava  

International Nuclear Information System (INIS)

Postrenal segment anomalies of inferior vena cava such as bilateral inferior vena cava and left-sided inferior vena cava can simulate lymphadenopathy on CT scan and these anomalous veins need consideration in retroperitoneal operations such as procedures for prevention of venous embolism, splenorenal shunt operation and aortic prosthetic replacement. Retrocaval ureter is a rare cause of obstructive uropathy or medical deviation of ureter. We analyzed 16 cases of postrenal segment anomalies diagnosed by CT, vena cavography, retrograde pyelography and ultrasonography including six rare positional anomalies at hepatic segment of inferior vena cava diagnosed by cardiac angiography. The results were as follows. 1. Postrenal segment anomalies were 6 cases of bilateral IVC, 8 cases of left-sided IVC and 2 cases of retrocaval ureters. On CT scan, 3 cases of bilateral IVC and 4 cases of left-sided IVC were accompanied by malignant tumors, but caval veins could be discriminated from enlarged nodes because of continuous tubular nature of vein on consecutive sections with homogeneous strong enhancement. Two cases of retrocaval ureters showed hydroureteronephrosis due to ureteral compression by IVC. 2. Hepatic segment anomalies were 6 cases. Five cases of IVC on left side of vertebra crossed midline at live to enter right-sided right atrium and one case of IVC on right side crossed midline to enter left-sided right atrium. Four cases of complex cardiac anomalies, 4 cases of annapolis and 2 cases of situs ambiguous were associated with these anomalies.

Congenital anomalies of the venae cavae: embryological origin, imaging features and report of three new variants  

Energy Technology Data Exchange (ETDEWEB)

Due to the complexity of their developmental stages, the venae cavae may undergo a very large number of congenital anomalies. All the possible abnormalities which, to our knowledge, have been observed in the literature are reported, differentiating those of the superior vena cava and the azygos system, those of the inferior vena cava and the complex anomalies that concern the venous system as a whole. Moreover, we present three new variants: a right double inferior vena cava with azygos continuation of the posterior-medial vein; an agenesis of the superior vena cava with drainage through the azygos and hemiazygos veins to the inferior vena cava; and a double inferior vena cava with hemiazygos and azygos continuation of the left one.

Superior vena cava obstruction associated with nephrogenic systemic fibrosis.  

Science.gov (United States)

A 56-year-old woman with hypertension-induced end stage renal disease presented with skin thickening and mottled discoloration. Cutaneous biopsy showed increased dermal fibroblasts embedded in fibromyxoid stroma with scattered perivascular and interstitial mononuclear cells. Immunohistochemistry revealed prominent CD34+ dendritic cells in septal spaces, consistent with Nephrogenic Systemic Fibrosis (NSF). Seven years and two years prior she had received a gadolinium-based contrast agent (GBCA). She died due to NSF. Gross autopsy revealed a thickened and stenotic superior vena cava (SVC). Extensive fibrosis of the SVC, dermis, and subcutaneous tissue was noted, together with hyalinized collagen fibers within the muscular wall of the intestines and dura mater. These findings support the importance of skin changes in the recognition of life threatening extracutaneous tissue involvement in NSF. PMID:24809889

Bilateral inferior vena cava filter insertion in a patient with duplication of the infrarenal vena cava.  

LENUS (Irish Health Repository)

BACKGROUND: Inferior vena cava (IVC) filter insertion is a commonly performed procedure for indications such as recurrent pulmonary emboli or contraindication to anticoagulation. Symptomatic duplication of the IVC is exceedingly rare with only a handful of cases being described in the literature. AIM: We report an unusual case of a patient with symptomatic duplication of the IVC. RESULT: A 53-year-old woman presented at our hospital for resection of a cerebral metastasis from a non-small cell lung cancer following a recent diagnosis of bilateral lower limb deep venous thrombosis. This required perioperative reversal of anticoagulation and IVC filter insertion. Conventional venography performed during filter insertion documented the existence of a duplicated IVC. CONCLUSION: We present a case of a symptomatic duplication of the IVC requiring filter insertion. We review the developmental anatomy of the IVC along with the diagnostic findings and management strategies available.

Leiomyosarcoma of the inferior vena cava--an unusual case.  

Science.gov (United States)

Primary tumors arising from great vessels like the aorta, pulmonary artery or inferior vena cava (IVC) are rare. The latter is the commonest site of its occurrence. It arises from the smooth muscle cells of the vessel wall. Aggressive surgical management should be attempted to excise it whenever possible. We describe a case of primary inferior vena cava tumor involving all three segments of the abdominal inferior vena cava infrarenal, suprarenal and retrohepatic vena cava, along with right kidney, right adrenal as well as right hepatic vein and left renal vein. We resected it completely without reconstruction of the IVC. The patient is doing well seven months after surgery without having any renal insufficiency, hepatic insufficiency or leg edema and having optimum quality of life. To our knowledge, this is the first case of such a long segment IVC leiomyosarcoma treated without IVC reconstruction, and despite its extent and concomitant involvement of the right kidney, right adrenal, right hepatic vein and left renal vein, it had a favorable response combining prolongation of survival and satisfactory quality of life.

Congenital interruption of the inferior vena cava: A case report  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Congenital interruption of the inferior vena cava is a rare entity. It can be associated with other organ and system malformations, especially the cardiovascular system. Usually, patients are asymptomatic and the anomaly is therefore diagnosed incidentally. In some cases it can be of clinical importance. Case Outline. A 22-year-old female was diagnosed during evaluation of cardiac symptoms. Clinical examination showed normal findings. CT angiography and cavography were used to establish the diagnosis of inferior vena cava interruption. Since there was no need for surgical intervention the patient was discharged in good condition. During a five year follow-up no significant health problems were noted with patient leading normal life. Conclusion. Diagnostic tools used to establish the diagnosis of inferior vena cava interruption are ultrasonography, as well as CT and MR angiography and phlebography. Mediastinal masses found on chest roentgenogram must raise suspicion of inferior vena cava interruption. Although the anomaly is rare, physicians should be aware of the infrahepatic interruption of the IVC, especially because it can present at any age.

Laceration of the inferior vena cava of angiographic demonstration  

Energy Technology Data Exchange (ETDEWEB)

Laceration of the inferior vena cava (IVC) often presents as an acute surgical emergency requiring immediate operative intervention. We show that when the patient's clinical condition permits, angiography may delineate the site of caval laceration and active hemorrhage, and identify associated arterial injuries. Contrast extravasation from the IVC also is reported for the first time.

Computed tomography of leiomyosarcoma of the inferior vena cava  

Energy Technology Data Exchange (ETDEWEB)

Two cases of leiomyosarcoma of the inferior vena cava are described, with emphasis on their computed tomographic (CT) appearance. Sixty-two previously reported cases are reviewed. Four patterns of tumor growth are described: extrinsic, intraluminal, combined extrinsic and intraluminal, and intramural. CT may clearly define these pattens and suggest the proper diagnosis.

Inferior vena cava obstruction presenting as an abdominal  

Energy Technology Data Exchange (ETDEWEB)

Obstruction of the inferior vena cava (IVA) was observed as an abdominal mass on the plain radiograph in an asymptomatic patient. The obstruction had developed immediately below the renal veins, and markedly dilated varices were present. The appearance differed from that of the usual congenital caval variants and may have been the result of caval thrombosis in utero.

Superior vena cava syndrome: role of the interventionalist.  

Science.gov (United States)

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. PMID:23415716

Injuries of the retrohepatic inferior vena cava and the liver  

Directory of Open Access Journals (Sweden)

Full Text Available Beckground. Injuries of the retrohepatic inferior vena cava, and the liver have mortality rate up to 71-78%. We presented a patient with combined injury of the retrohepatic inferior vena cava, liver, craniocerebral and thoracic traumas, inflicted in a traffic accident. Case report. Man, 20 years old has been injured in a traffic accident. At admission, 20 minutes after the injury, the patient was comatose and hypotensive. Bloody content was obtained by abdominal tracer. The patient underwent emergent laparotomy, utilizing trifurcated incision and cell saver device. Abdominal exploration revealed two liters of free blood and massive retroperitoneal hematoma. Manual compression of the liver was done, as well as perihepatic packing, complete hepatic vascular exclusion and mobilization of the right liver lobe. Due to impressive chemodynamic instability supraceliac aortic clamping was performed. Upon exposure of the retrohepatic inferior vena cava and right liver lobe, multiple lacerations of retrohepatic inferior vena cava and right hepatic vein, and right hepatic vein avulsion were found. We also identified an injury of VII and VIII segments of the liver (grade V according to the Moore's classification. Nonexpansive hepatoduodenal ligament hematoma and the injury of II and III segments of the liver group II/III according to Moore were found. Venorrhaphy of the inferior vena cava was done in the area of circumference of the right hepatic vein, a portion of which served as autologous vein patch. Continuous prolene 3/0 venorrhaphy of the distal caval laceration was done. Total caval and aorta clamping time of the inferior vena cava was 41 minutes. Atypical resection, debridment, of hepatic segments was done by using a harmonic scalpel. Hepatoduodenal ligament was declamped after 65 minutes. Fibrin glue was applied on the resectioned area of liver. The patient received 3.2 l of autologuos blood transfusion with 5 units of packed red blood cells, 6 units of fresh frozen plasma, 13 units of concentrated thrombocytes and 15 units of cryoprecipitates. Due to coagulopathy, factor rVIIa was administered. Bilateral toracal drainage was done. Small bilateral contusions of the frontal part of the brain were noticed but the patient successfully recovered and was dismissed after three weeks. Conclusion. Combined injuries of the inferior vena cava and the liver befall into the most complex vascular traumas, thus representing a challenge for any complete medical team to manage them. The patient presented in our study was urgently transported to the hospital, immediately operated on applying modern doctrines of anesthesiology, transfusiology and vascular surgery that, all together, resulted into favorable treatment outcome with no distant complications.

Advanced Techniques for Removal of Retrievable Inferior Vena Cava Filters  

Energy Technology Data Exchange (ETDEWEB)

Inferior vena cava (IVC) filters have proven valuable for the prevention of primary or recurrent pulmonary embolism in selected patients with or at high risk for venous thromboembolic disease. Their use has become commonplace, and the numbers implanted increase annually. During the last 3 years, in the United States, the percentage of annually placed optional filters, i.e., filters than can remain as permanent filters or potentially be retrieved, has consistently exceeded that of permanent filters. In parallel, the complications of long- or short-term filtration have become increasingly evident to physicians, regulatory agencies, and the public. Most filter removals are uneventful, with a high degree of success. When routine filter-retrieval techniques prove unsuccessful, progressively more advanced tools and skill sets must be used to enhance filter-retrieval success. These techniques should be used with caution to avoid damage to the filter or cava during IVC retrieval. This review describes the complex techniques for filter retrieval, including use of additional snares, guidewires, angioplasty balloons, and mechanical and thermal approaches as well as illustrates their specific application.

Directory of Open Access Journals (Sweden)

Full Text Available Leiomyosarcoma of the inferior vena cava is an extremely rare tumor, and it is reported to have a poor prognosis. The clinical findings are nonspecific and may precede the diagnosis by several years. Symptoms depend on the location and extension of the tumor. A complete surgical resection is the only proven therapeutic modality that prolongs the survival in patients with this lesion. We report a case of a 50 year-old patient with inferior vena cava leiomyosarcoma, who was submitted to a surgical treatment.

Perforation of an inferior vena cava filter by one the filter device hooks is a recognized possible complication of this device. We describe a case of surgical excision of a permanent inferior vena cava filter associated with multiple perforations of surrounding structures by each of the 6 hooks of the device. Structures affected include the third lumbar vertebral body, transverse mesocolon, the infrarenal aorta, the duodenum, and the psoas muscle. A thorough understanding of the filter design and adequate preoperative imaging were vital in planning the safe surgical excision of this device. PMID:24084266

Twelve years experience of vena cava filtration.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Fourteen patients have required vena caval interruption in a period of 12 years at St Thomas' Hospital. Half of these patients had an underlying malignancy. None of these patients have had clinical or lung scan evidence of recurrent emboli. There were no deaths related to filter insertion and no patient died of a pulmonary embolism. Vena caval interruption is a procedure that is rarely necessary but may be valuable in carefully selected patients.

Superior vena cava syndrome caused by embolisation of liquid Onyx  

Science.gov (United States)

Superior vena cava syndrome (SVCS) is usually caused by a malignancy or the presence of an intravascular device in a central vein. A 74-year-old male with a history of a superior vena cava (SVC) stent underwent embolisation of a brain arterio-venous malformation through the right meningeal artery with liquid Onyx. Two weeks later he presented with acute respiratory failure, upper airway obstruction, plethora, varices of the chest wall and stridor. He was intubated and placed on mechanical ventilatory support. Chest imaging revealed a linear structure in the SVC, extending to the right atrium. Interventional radiology removed the material, which was determined to be liquid Onyx. Venous pressures of the right internal jugular vein decreased after removal of the material. The symptoms resolved and patient was successfully extubated. This is the first reported case of SVCS caused by liquid Onyx.

Modeling Flow Past a Tilted Vena Cava Filter  

Energy Technology Data Exchange (ETDEWEB)

Inferior vena cava filters are medical devices used to prevent pulmonary embolism (PE) from deep vein thrombosis. In particular, retrievable filters are well-suited for patients who are unresponsive to anticoagulation therapy and whose risk of PE decreased with time. The goal of this work is to use computational fluid dynamics to evaluate the flow past an unoccluded and partially occluded Celect inferior vena cava filter. In particular, the hemodynamic response to thrombus volume and filter tilt is examined, and the results are compared with flow conditions that are known to be thrombogenic. A computer model of the filter inside a model vena cava is constructed using high resolution digital photographs and methods of computer aided design. The models are parameterized using the Overture software framework, and a collection of overlapping grids is constructed to discretize the flow domain. The incompressible Navier-Stokes equations are solved, and the characteristics of the flow (i.e., velocity contours and wall shear stresses) are computed. The volume of stagnant and recirculating flow increases with thrombus volume. In addition, as the filter increases tilt, the cava wall adjacent to the tilted filter is subjected to low velocity flow that gives rise to regions of low wall shear stress. The results demonstrate the ease of IVC filter modeling with the Overture software framework. Flow conditions caused by the tilted Celect filter may elevate the risk of intrafilter thrombosis and facilitate vascular remodeling. This latter condition also increases the risk of penetration and potential incorporation of the hook of the filter into the vena caval wall, thereby complicating filter retrieval. Consequently, severe tilt at the time of filter deployment may warrant early clinical intervention.

Detection by means of CT of inferior vena cava filters  

International Nuclear Information System (INIS)

Vena cava filters are an excellent tool for the prevention of pulmonary embolism (PE) in patients with deep vein thrombosis (DVT) of the lower limbs. However, these devices are not entirely free of complications as thrombi can develop inside them, threatening to occlude them completely. The objective of this report is to study the incidence of thrombosis in vena cava filters, as well as their impact on prognosis. We also mention the importance of CT as an imaging technique in the study of this complication. We present 30 patients in whom different filters were implanted and their prospective follow-up by means of CT over a mean follow-up period of 36 months. Chi-square analysis was used to determine whether there was a significant relationship among the complications encountered (p<0,05), and their course over time was studied by means of Kaplan-Meyer curves. Five cases (16%) of complete thrombosis of the filter were observed among patients in whom the Gunther model had been implanted, yielding an index of probability of complete permeability of the inferior vena cava at 13 months of 82%. Thrombi of different degrees (between 5% and 60%) were also observed inside the filter in ten patients (33%) with Gunther, Simon-Nitional and LGM models. Filter thrombosis was not significantly associated with the onset of recurrent PE or of venous disorders involving lower limbs, the relationship between PE and preimplantation presence of inferior vena cava thrombosis was significant (p<0.01). It was also observed that post implantation anti coagulation did not significantly prevent later onset of filter thrombosis. (Author)

Experimental study of domestic inferior vena cava filter comparative to Antheor temporary vena cava filter in vitro  

International Nuclear Information System (INIS)

Objective: To evaluate clot capturing efficacy and stability of a new domestic designed inferior vena cava filter (DDIVCF) by comparing with Anthem temporary vena cava filter in vitro. Methods: (1)The DDIVCF and Antheor filter were tested in a flow model simulated the inferior vena cava (IVC) with 20 mm and 25 mm in diameter. The swine clots of four sizes were used: 3 mm x 20 mm, 3 mm x 30 mm, 6 mm x 20 mm, 6 mm x 30 mm. The clot capturing capacity was observed in horizontal position. (2) The stability was observed by measuring the comparative moving distance of 6 mm x 30 mm clots after clot trapping. Results: (1) DDIVCF capture rates were 34%, 56%, 82%, 94% and 26%, 38%, 56%, 86% for the 20 mm and 25 mm IVC models of four different sizes clots respectively, comparing with 54%, 64%, 86%, 96% and 38%, 44%, 68%, 90% respectively of Anthem temporary vena cava filter. The capture rates of DDIVCF and Antheor filter showed no significant differences of 3 mm x 30 mm, 6mm x 20 mm and 6 mm x 30 mm clots in 20 mm and 25 mm IVC models (P>0.05). (2) There was a few caudal migration with no significant difference (P>0.05). The filter migration distances were (0.6±0.3) cm and (1.0±0.1) cm respectively in the 20 mm and 25 mm IVC models with most clots of 6 mm x 30 mm were captured, comparing with (0.4±0.1) cm and (0.8 ±0.3) cm respectively for Antheor filter. Conclusions: DDIVCF is a stable and effective filter in an in-vitro model experiment but application in vivo would rather be further evaluated through more animal experiments. (authors)

Treatment of malignant obstruction of the superior vena cava with the self-expanding Wallstent.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

BACKGROUND--Obstruction of the superior vena cava (SVC) in malignant disease can cause considerable distress to patients. Symptomatic relief can be achieved by the percutaneous implantation of a self-expanding stent (Wallstent) into the stenosis. METHODS--Fourteen patients with obstruction of the SVC were treated with one to three Wallstent endoprostheses. They suffered from advanced bronchogenic carcinoma (n = 12), thyroid carcinoma (n = 1), and breast carcinoma (n = 1). The indication for s...

Radiation-induced superior vena cava syndrome.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A 59-year-old man developed superior vena caval obstruction 20 years after receiving a radiation treatment for primary germinal cell tumor of the mediastinum. Venous decompression was achieved by anastomosing a 10-mm ringed polytetrafluoroethylene graft from the left internal jugular vein to the right atrium, which yielded immediate relief of symptoms. A left internal jugular venogram demonstrated graft patency 11 months post-operatively, and the patient remained free of symptoms of superior ...

Morphofunctional characterization of decellularized vena cava as tissue engineering scaffolds.  

Science.gov (United States)

Clinical experience for peripheral arterial disease treatment shows poor results when synthetic grafts are used to approach infrapopliteal arterial segments. However, tissue engineering may be an option to yield surrogate biocompatible neovessels. Thus, biological decellularized scaffolds could provide natural tissue architecture to use in tissue engineering, when the absence of ideal autologous veins reduces surgical options. The goal of this study was to evaluate different chemical induced decellularization protocols of the inferior vena cava of rabbits. They were decellularized with Triton X100 (TX100), sodium dodecyl sulfate (SDS) or sodium deoxycholate (DS). Afterwards, we assessed the remaining extracellular matrix (ECM) integrity, residual toxicity and the biomechanical resistance of the scaffolds. Our results showed that TX100 was not effective to remove the cells, while protocols using SDS 1% for 2h and DS 2% for 1h, efficiently removed the cells and were better characterized. These scaffolds preserved the original organization of ECM. In addition, the residual toxicity assessment did not reveal statistically significant changes while decellularized scaffolds retained the equivalent biomechanical properties when compared with the control. Our results concluded that protocols using SDS and DS were effective at obtaining decellularized scaffolds, which may be useful for blood vessel tissue engineering. PMID:24929113

The initial experience of transjugular retrieval of Geunther Tulip inferior vena cava filters  

International Nuclear Information System (INIS)

Objective: To explore the indications and technical procedures of transjugular retrieval of Geunther Tulip inferior vena cava filters. Methods: Seventy-four patients (40 males and 34 females with a mean age of 45.8 years) with acute lower extremity deep venous thrombosis encountered in our hospital from September 2007 to Mar 2009 were involved in this study. The onset of the disease was from one day to 14 days. Clinical symptoms included swelling, pain, cyanosis or pallescence of the affected limb with higher or normal skin temperature. Thirty-one patients who complicated with pulmonary embolism suffered from dyspnoea, chest pain, hemoptysis, etc. Implantation of Geunther Tulip retrievable inferior vena cava filters through femoral or right internal jugular vein was carried out, which was followed by intravenous transcatheter thrombolysis. Vascular ultrasound and angiography showed no fresh or free thrombus in 12-80 days after initial treatment, then the Geunther Tulip filter was taken out from right internal jugular vein, and inferior vena cavography was performed again. All patients accepted anticoagulation and antibiotic treatment for 3-5 days after operation. A follow-up lasting for 4-12 months was made. Results: Successful implantation of Geunther Tulip retrievable inferior vena cava filter with only one session was obtained in all 74 patients. During implantation procedure one filter became tilted 25 degrees. Successful removal of Geunther Tulip retrievable inferior vena cava filter was achieved in 40 patients in 41.3 days (12-80 days) after the filter was delivered, and the procedure cost only 5.8 minutes (1-115 minutes) with a successful rate of 97.6% (40/41). Failure of retrieval of IVC filter due to compact adhesion of the filter to IVC wall happened in one patient. Inferior vena cavography again confirmed that there was no any sign of vascular perforation or rupture. Retrieval of IVC filter was not performed in other 33 patients and no clinical manifestations of pulmonary embolism or inferior vena cava occlusion emerged during follow-up period. Conclusion: For the treatment of acute lower extremity deep venous thrombosis, interventional transjugular retrieval of Geunther Tulip IVC Filters has some advantages, including retrievable time, i.e. a long time window for thrombolysis therapy, high successful rate of retrieval and satisfactory clinical efficacy.

Roentgenologic diagnosis of pulmonary veins pathologically inflowing into vena cava inferior  

International Nuclear Information System (INIS)

The authors considered the problem of X-ray semiotics of the right inferior pulmonary vein pathologically inflowing in the vena cava inferior (4 patients) and the false syndrome of the ''Turkish sabre'' (1 patients). Among the patients there were 2 adults and 3 children. It was noted that the abnormal inflowing of the right lower lobe vein in the vena cava inferior was often combined with different types of heart diseases and defects of the major vessels, mainly with the defect of the interatrial septum, the open arterial canal and hypoplasia of the right pulmonary artery. Radiodiagnosis for this group of patients should incorporate, in addition to routine X-ray methods, angiographic investigation, and its volume in each case should be determined on an individual basis

Synchronous adrenal metastasis and an inferior vena cava tumor thrombus from an ovarian carcinoma.  

Science.gov (United States)

A 60-year-old woman presented with synchronous adrenal metastasis and an inferior vena cava tumor thrombus in the adrenal vein that developed from an ovarian carcinoma. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and right adrenalectomy with caval tumor thrombectomy for treatment. Microscopic examination revealed a clear cell ovarian carcinoma and a metastatic adrenal tumor. The patient is clinically free of disease after 6 years of follow-up. There have been no reports of synchronous adrenal metastasis with an inferior vena cava thrombus that developed from an ovarian carcinoma. As several reports have described the long-term survival after adrenalectomy for the treatment of isolated adrenal metastasis, clinicians should be aware of this potential occurrence so that patients can be appropriately treated.

Perforated inferior vena cava filters as the cause of unclear abdominal pain.  

Science.gov (United States)

Inferior vena cava filters are considered a valuable therapeutic option in patients with deep vein thrombosis, subsequent pulmonary emboli, and contraindication for anticoagulation. However, these filters bear the risk of rare but serious complications (e.g., symptomatic caval perforation). We report our experiences with retrievable vena cava filters by means of an actual case and review the recent literature with special regard to filter-dependent delayed symptomatic vena cava perforations. Here, an inferior vena cava filter could be identified as the source of a patient's abdominal pain; after an interventional retrieval approach had failed, open surgical removal became necessary and led to the instant relief of this patient's symptoms. Retrievable vena cava filter removal should be performed in all cases as soon as no longer needed to avoid fatal complications. PMID:23498323

A case of thoracic esophageal cancer with an unusual type of duplicated inferior vena cava.  

Science.gov (United States)

We describe here a thoracic esophageal cancer with an unusual type of duplicated inferior vena cava. A 58-year-old man was referred to our hospital because a tumor in his lower esophagus had been identified by endoscopy and radiology. Computed tomography scans showed an unusual type of duplicated inferior vena cava characterized by both common iliac veins flowing back into the left-sided inferior vena cava, which drained into the azygos vein, whereas the right-sided one had no drainage. Esophagectomy was performed 3 weeks later after preoperative chemotherapy. Because the patient could have developed thrombosis of the left-sided inferior vena cava and severe hypotension caused by decreased venous return to the heart if the azygos vein had been severed, the azygos vein was preserved. Thus, when performing surgery for thoracic esophageal cancer, the surgeon should check for a duplicated inferior vena cava and preserve the azygos vein if necessary. PMID:24470167

Preliminary experimental study of retrievable nitinol inferior vena cava filter  

International Nuclear Information System (INIS)

Objective: To evaluate, in vitro and in an animal model together with the placement, stability, clot capturing efficacy, retrieval and safety of a new non-invasive retrievable nitinol inferior vena cava filter (RNIVCF) for temporary or permanent use. Methods: RNIVCF were made by wrapping nitinol monofilament wire on a steel mandrill to form a steric configuration. A 5-F Teflon sheath/dilator was taken for placement and retrieval. In vitro clots' trapping was assessed with size of 2.5/3/4-mm-diameter clots. Twenty adult mongrel dogs were used in this study. 2.5-mm-diameter homologous radiopaque clots (2.5-mm-HRC) were injected into IVC until the experimental animals die of acute pulmonary embolism (PE) and then to determine the minimum fatal quantity of clots in 8 dogs. RNIVCFs were introduced into the inferior vena cava in 12 dogs. For 10 animals, 10-ml 2.5-mm-HRC were injected below the filter to test its thrombus-trapping efficacy. The retrieval of filter was attempted on the 7th day after placement in two other dogs. Plain films of the abdomen and chest were made to document the effectiveness of the filter. Results: Initial experimental study showed that the RNIVCF functioned as intended. In vitro all 3 and 4-mm-diameter clots injected in the device simulating IVC flow was trapped by the filter. However, 95%-100% 2.5-mm-diameter clots were also captured by it. More than 10-ml 2.5-mm-HRC with once injection into IVC could cause the death of experimental animals due to acute PE in per-experiment. RNIVCF could be easily and successfully placed percutaneously in the inferior vena cava of the dogs through a 5-F sheath. The filter was accurately positioned in the inferior vena cava by moving the retrieval wire. All 13 RNIVCFs were placed in 12 dogs, one of those has double inferior vena cava and two filters were implanted. The filters trapped these 2.5-mm-diameter clots in the iliac veins of 8 dogs and none of them died of acute PE. But the initial two dogs with two original RNIVCF died of acute PE due to hypertension of the inferior vena cava below the filters caused by injecting too much clots to force the trapped clots passing through the filters. Therefore, only 10-ml clots was necessary for injection into each the IVC of the dogs and thus the stabilized portion of the original RNIVCF can change into three-petals-quincunx shape. Two filters were retrieved successfully through the sheath/dilator in the 7th day after placement without difficulty. Conclusion: RNIVCF is a kind of sophisticated device for retracting emboli. It can be sited percutaneously with 5F delivery permanently or temporarily in stable condition. The smooth contours cause no traumatic effect especially for retrieving small emboli

Sodium nitroprusside activates potassium channels in the vena cava in normotensive but not in hypertensive rats.  

Science.gov (United States)

Despite the importance of the venous system in the regulation of blood pressure, there are few studies that evaluate venous function in health and disease, and the effects of drugs on venous function. Blood pressure depends directly on the peripheral resistance and cardiac output. Unlike the peripheral resistance, in which the contractile activity of the arteries is the key factor, cardiac output depends primarily on the venomotor tone. An increase in cardiac blood pressure can be caused by an increase in blood volume, structural changes in the walls of the veins, leading to a reduced compliance thereof, or an increase in the contractile activity of venous smooth muscle. This study examined the effect of sodium nitroprusside (SNP), a classical nitric oxide donor, on vascular relaxation in the vena cava from normotensive (2K) and renal hypertensive (2K-1C) rats. We studied the effect of this compound in vena cava rings from normotensive and renal hypertensive rats. We showed for the first time that the vascular relaxation induced by SNP is impaired in vena cavas from hypertensive rats because of an impaired functional activity of potassium channels. Another relevant finding of this study is that the sarcoplasmic reticulum Ca(2+) ATPase is not involved in the venorelaxation induced by SNP. PMID:23784507

Safety and Efficacy of the Gunther Tulip Retrievable Vena Cava Filter: Midterm Outcomes  

Energy Technology Data Exchange (ETDEWEB)

PurposeTo evaluate of the medium-term integrity, efficacy, and complication rate associated with the Gunther Tulip vena cava filter.MethodsA retrospective study was performed of 369 consecutive patients who had infrarenal Gunther Tulip inferior vena cava filters placed over a 5-year period. The mean patient age was 61.8 years, and 59 % were men. Venous thromboembolic disease and a contraindication to or complication of anticoagulation were the indications for filter placement in 86 % of patients; 14 % were placed for prophylaxis in patients with a mean of 2.3 risk factors. Follow-up was obtained by review of medical and radiologic records.ResultsMean clinical follow-up was 780 days. New or recurrent pulmonary embolus occurred in 12 patients (3.3 %). New or recurrent deep-vein thrombosis occurred in 53 patients (14.4 %). There were no symptomatic fractures, migrations, or caval perforations. Imaging follow-up in 287 patients (77.8 %) at a mean of 731 days revealed a single (0.3 %) asymptomatic fracture, migration greater than 2 cm in 36 patients (12.5 %), and no case of embolization. Of 122 patients with CT scans, asymptomatic perforations were identified in 53 patients (43.4 %) at a mean 757 days.ConclusionThe Gunther Tulip filter was safe and effective at 2-year follow-up. Complication rates were similar to those reported for permanent inferior vena cava filters.

In high fractionate dose group, six of eleven patients (54.5%) exhibited relief of symptoms in 1-2 days, and additional three patients of nine (81.7%) within 3-4 days, while standard fractionated dose treatment is not effective to achieve initial relief of symptoms. 2. Graded response by total dose was correlated with total dose rather than dose fractionation. 3. Overall one year survival rate with superior vana cava syndrome was 9.1% and mean survival was 4.2 months

Symptomatic caval penetration by a Celect inferior vena cava filter  

Energy Technology Data Exchange (ETDEWEB)

We report a case of penetration of the inferior vena cava (IVC) by all four primary struts of a Celect caval filter in a 17-year-old girl with Klippel-Trenaunay syndrome. The girl presented with acute lower abdominal and right leg pain 17 days after filter insertion. An abdominal radiograph demonstrated that the filter had moved caudally and that the primary struts had splayed considerably since insertion. Contrast-enhanced CT confirmed that all four primary struts had penetrated the IVC wall. There was a small amount of retroperitoneal hemorrhage. The surrounding vessels and viscera were intact. The filter was subsequently retrieved without complication. (orig.)

Renal transplantation in a child with thrombosed inferior vena cava.  

Science.gov (United States)

The external iliac vein is commonly used in renal transplantation for vascular anastomosis of the allograft renal vein. However, there are rare instances when the transplant surgeon may encounter thrombosis of the ilio-caval vein during surgery, making renal transplantation a challenge. Often, these patients are considered unsuitable for renal transplantation. We report a case of thrombosis of the inferior vena cava in an asymptomatic pediatric patient in whom the splenic vein was used, at transplantation, for venous drainage. This case highlights that pre-operative Doppler screening should be performed in all potential renal transplant recipients. PMID:24626005

Mesoaortic entrapment of a left inferior vena cava  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A persistent left inferior vena cava (IVC) is a rare anomaly, with a reported incidence of only 0.2-0.5%. When present, it courses between the superior mesenteric artery and the aorta to continue as the right IVC, similar to the course of a left renal vein (LRV). This anomaly is usually asymptomatic, but there may be vague abdominal complaints if the IVC is compressed in the mesoaortic angle. Although symptomatic compression of the LRV (anterior nutcracker syndrome) is well recognized, there ...

Percutaneous treatment of superior vena cava syndrome using metallic stents  

International Nuclear Information System (INIS)

The purpose of this study was to evaluate the results of treatment of superior vena cava syndrome (SVCS) in patients with benign and malignant disease using expandable metallic stent. From January 1995 to April 2000, 87 expandable stents were implanted in 82 patients (59 men, 23 women; mean age 57.8 years, age range 39-79 years) for the treatment of SVCS. The SVCS was defined as symptomatic bilateral obstruction of venous drainage from head, neck and upper extremities. In 68 patients SVCS was due to malignant neoplasia, and in 14 cases it was due to benign aetiology. All patients were treated with expandable stent. We implanted 81 Wallstent prostheses and 6 Palmaz stents. Adjuvant thrombolysis was applied in 12 patients who required fibrinolysis. After recanalization, the stent was implanted in all cases in SVC (infra- or supra-azygos vein). All patients were treated with heparin of low molecular weight (HBPM) during 6 months. Patency was analyzed according to clinical symptoms and Doppler US or venograms exploration. Technical success was observed in all cases. Clinical success was reached in 78 of 82 patients (95.1%) (absence of symptoms in 2 or 3 days). Four patients suffered immediate thrombosis which required fibrinolitic treatment with a new prosthesis placement in 1 case. The follow-up for the malignant process was of 7.1 months (range 1-39 months) and in benign cases was 31.2 months (range 11-61 months). Sixty-two (91.1%) patients with malignancy died without SVCS symptomatology. All the patients with benign pathology are alive. Clinical primary patency in malignant cases was 87% with assisted patency of 96.2%. Endovascular therapy using metallic stent and thrombolysis is a successful method to treat SVCS due to benign or malignant aetiology. (orig.)

Clinical results with a detachable temporary vena cava filter  

International Nuclear Information System (INIS)

Purpose: Evaluation of the feasibility of implantation and explantation and evaluation of the efficacy of a detachable and retrievable temporary vena cava filter. Materials and Method: The temporary vena cava filter ''OptEase'' (Cordis) is a nitinol filter derived from the ''TrapEase'' (Cordis) permanent filter, which is implantable transjugularly or transfemorally. In contrast to other temporary filters, this type can be detached and is not fixed on a catheter during implantation. Therefore, it is usable as a temporary as well as a permanent filter which can be retrieved up to 12 days after detachment with a special catheter using the loop technique. The ''OptEase'' filter was implanted in 11 patients ranging in age from 19 to 82 (mean age 30 years). In 10 patients the filter was transfemorally implanted and explanted. In 1 patient implantation was performed transjugularly prior to surgery and explantation was performed transfemorally after surgery. All patients had a deep vein thrombosis or iliac vein thrombosis. In 3 patients the filter was implanted prior to surgery. In 2 patients pulmonary embolism was identified. In 5 patients the filter was implanted prophylactically because of deep vein thrombosis according to interdisciplinary diagnosis. Results: No pulmonary embolism occurred during implantation. All filters were able to be retrieved without complications using the loop technique on the 6th, 8th, 12th and 13th day. No captured thrombus material was in the filter. (orig.)

Treatment of Superior Vena Cava (SVC) Syndrome and Inferior Vena Cava (IVC) Thrombosis in a Patient with Colorectal Cancer: Combination of SVC Stenting and IVC Filter Placement to Palliate Symptoms and Pave the Way for Port Implantation  

International Nuclear Information System (INIS)

Thrombosis of the inferior vena cava is a life-threatening complication in cancer patients leading to pulmonary embolism. These patients can also be affected by superior vena cava syndrome causing dyspnea followed by trunk or extremity swelling. We report the case of a 61-year-old female suffering from an extended colorectal tumor who became affected by both of the mentioned complications. Due to thrombus formation within the right vena jugularis interna, thrombosis of the inferior vena cava, and superior vena cava syndrome, a combined interventional procedure via a left jugular access with stenting of the superior vena cava and filter placement into the inferior vena cava was performed As a consequence, relief of the patient's symptoms, prevention of pulmonary embolism, and paving of the way for further venous chemotherapy were achieved.

Retrocaval ureter and anomalies of inferior vena cava  

International Nuclear Information System (INIS)

We report two cases of retrocaval ureter: one with the usual hook-shaped pattern of the course of ureter (Type 1 according to Kenawi and Williams) and the other with the ureter medially displaced in a large curving fashion without kinking or obstruction. (Type 2). The second case was diagnosed on CT without resorting to any invasive procedure. It can be classified as Type 2 of Kenawi and Williams because of the absence of obstruction and kinking of ureter. The first case is associated with a complicated anomaly of inferior vena cava previously not reported which shows the duplication of infrarenal segment of cava with azygos continuation via the right persistent supracardinal vein. This anomaly is also complicated by the persistent posterior cardinal vein which is continuous with the normal prerenal segment of cava after receiving the right renal vein. This persistent posterior cardinal vein is the cause of retrocaval ureter in this case. It is also stressed that the knowledge of various caval anomalies is important in the interpretation of CT.

Abnormal draining of great cardiac vein into superior vena cava  

International Nuclear Information System (INIS)

Full text: A 47-year-old man presented with atypical chest pain in last three months. Physical examination findings were normal. ECG showed normal sinus rhythm. Transthoracic echocardiography revealed normal left and right ventricular systolic functions. ECG gated coronary CT angiography was performed. The patient's coronary CT angiography showed normal coronary arteries, however the great cardiac vein course was abnormal. The course of the vein was not in atrioventicular groove, bypassing the coronary sinus and draining to superior vena cava. The coronary sinus of patient is formed by posterior marginal vein, middle cardiac vein and lateral marginal vein and drained into the right atrium. We also observed subtle myocardial bridges on coronary arteries. Myocardial bridges appeared to explain patient's chest pain. With optimal medical therapy, the patient's symptoms resolved

A case report of superior vena cava obstruction.  

Science.gov (United States)

We report herein an 83-year-old gentleman with lung cancer who presented with nausea, complete atrioventricular (AV) block and presyncope. Despite a present temporary pacemaker, which had been inserted through the femoral vein 5 days previously, the patient had asystole attacks that resolved with atropine administration. Coronary angiography demonstrated no critical stenosis. Sick sinus syndrome was diagnosed, and permanent pacemaker implantation was decided. However, the guidewire could not be advanced into the superior vena cava (SVC). Right jugular venogram showed complete obstruction of the SVC. Subsequent computerized tomography also revealed its obstruction by a large lung tumor. Special attention should be given to patients with benign or malignant SVC syndrome before permanent pacemaker implantation. PMID:24351947

Simon nitinol vena cava filters: effectiveness and complications  

International Nuclear Information System (INIS)

Purpose: The aim of this retrospective analysis was to evaluate the clinical safety and effectiveness of the simon nitinol inferior vena cava filter (SNF) for prevention of pulmonary embolism. Patients and Methods: 117 patients (63 male, 54 female; aged 58.38 ± 14.59 years) underwent percutaneous implantation of an SNF from 1993 through 1999. Patient reports were retrospectively analysed for complications during and after implantation and deep venous thrombosis (DVT) and pulmonary embolism before and after implantation. Helical-CT with contrast media and plain abdominal radiography were performed on 35 patients, helical-CT alone on two patients. We checked the position and configuration of the SNF and looked for a perforation of the filter legs through the wall of the inferior vena cava (IVC). The IVC and deep pelvic veins were analysed for patency. Results: During implantation 10 of 117 (9%) patients had minor complications, major complications were reported in 0.9% (1/117). There was no significant increase in thrombosis of the deep pelvic veins and the IVC after implantation. Pulmonary re-embolism (PE) was documented in 9 out of 117 patients (7.7%). One out of the 35 examined patients (2.9%) showed a single strut fracture of the SNF. Tilting more than 15 was seen in 7 out of 37 patients (19%). Dislocation of the SNF more than 10 mm occurred in one out of 35 patients (2.9%), perforation through the wall of the IVC in all 37 patients. We found no occlusion of the IVC. (orig.)

CT diagnosis of tumor thrombus of the renal vein and inferior vena cava  

International Nuclear Information System (INIS)

We used computed tomography (CT) for diagnosis in 4 cases of renal tumor associated with tumor thrombus of the renal vein and inferior vana cava. The results obtained are described below: A total of 4 cases consisting of 3 cases of renal cell carcinoma and one case of squamous cell carcinoma of the renal pelvis, treated at the Jikei University Hospital during the six months period from January to June of 1979, were studied. The affected side was right in 3 cases and left in one case. In all of the former cases the tumor thrombus was extending from the renal vein to the inferior vena cava, while in the latter case it was confined in the renal vein. All these 4 cases received CT together with renal arteriography and inferior venacavography, followed by nephrectomy, and were confirmed of the presence of tumor thrombus in the renal vein and inferior vena cava operatively. CT findings revealed a pronounced enlargement of the renal vein, and tumor thrombus of the renal vein was diagnosed in all of the 4 cases. In 2 of 3 cases in which tumor thrombus extended to the inferior vena cava, the dilated renal vein was found to be connected to the slightly dilated inferior vena cava, while in the remaining one case the outline of the inferior vena cava was obscure, showing no clear dilatation. After contrast enhancement, a filling defect was seen in the inferior vena cava. CT findings of tumor thrombus in the vein indicated a dilatation of the renal vein and inferior vena cava. In addition, a filling defect was found after contrast enhancement, suggesting that CT is helpful as a diagnostic aid. (author)

Filtros de vena cava inferior en posición suprarrenal Suprarenal inferior vena cava filters. Retrospective review of 30 cases  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Inferior vena cava (IVC filters are used to prevent massive pulmonary embolism in cases where anticoagulation is contraindicated or has failed. It is usually implanted below the renal veins. In a few cases it is necessary to deploy the filter above them, with theoretical rísk of secondary renal failure. Aim: To report the experience with filters located above the renal veins. Patients and Methods: Medical records of all patients with percutaneous suprarenal filters are reviewed. Results: Between May 1993 and May 2007, 361 percutaneous IVC filter procedures were performed. In thirty patients aged 19 to 77 years (average 48years, 50% males, they were placed in suprarenalposition (8,3%. Suprarenal IVC filters were implanted in patients with extensive caval thrombosis, renal vein thrombosis extending to cava, displacement of previous IVC filters and double IVC system. Jugular vein approach was the access of choice. Technical success was 100%, no death or pulmonary embolism occurred. Patients were followed from 1 to 165 months (average 57 months. Eight deaths were recorded, five in patients with cáncer No patient had renal failure on follow up (average creatinine 0.90+0,26 mg/dL. Three patients developed a new deep vein thrombosis (10%, without pulmonary embolism. Conclusions: In this retrospective analysis of patients, suprarenal placement of IVC filters was not associated to secondary renal failure, and showed good short and long term results.

Migration of central lines from the superior vena cava to the azygous vein  

Energy Technology Data Exchange (ETDEWEB)

Aim: To report 11 cases of central venous access catheters migrating from the superior vena cava to the azygos vein in order to raise radiologists' awareness of this possibility. Materials and methods: This is a retrospective review of the clinical history and imaging of 11 patients whose central line migrated from the superior vena cava to the azygos vein. The time course of migration, access route of the catheters, outcome, and depth of placement in the superior vena cava were evaluated. Results: All of these catheters were placed from the left; six through the subclavian vein, four as PICC lines, and one from the left internal jugular vein. Seven of the catheters were originally positioned in the superior vena cava. Four of the catheters were originally positioned in the azygos vein and were repositioned into the superior vena cava at the time of placement. The time to migration ranged from 2 to 126 days, average 43 days. In three cases, the migration was not reported at the first opportunity, resulting in a delay in diagnosis ranging from 10 to 27 days. All but one of the catheters extended at least 3.5 cm (range 1.8-7 cm) below the top of the right mainstem bronchus when in the superior vena cava. Conclusion: Risk factors for migration into the azygos vein include placement from a left-sided approach and original positioning in the azygos vein with correction at placement. The depth of placement in the superior vena cava was not a protective factor. It is important to recognize migration because of the elevated risk of complications when central lines are placed in the azygos vein.

Ataques isquêmicos transitórios em paciente com síndrome da veia cava superior: relato de caso Transient ischemic attacks in a patient with superior vena cava obstruction: case report  

Directory of Open Access Journals (Sweden)

Full Text Available A síndrome da veia cava superior (SVCS é condição relativamente rara. Relatamos o caso de um paciente de 42 anos, masculino, hipertenso há 15 anos, que evoluiu com dor cervical e torácica há um um ano, sendo evidenciada oclusão de 95% da coronária direita. Submetido a angioplastia, porém com persistência da dor torácica. Posteriormente evoluiu com episódios recorrentes de hemiplegia à direita associados a crises hipertensivas, que melhoravam com medicamentos anti-hipertensivos. Pela presença de coloração vinhosa na face e acentuação durante os períodos de ataques isquêmicos transitórios, foi feita a suspeita diagnóstica de provável acometimento do sistema de drenagem venosa, confirmada à venografia pelo achado de dilatação da veia jugular direita e imagem de estreitamento importante na junção com a veia cava superior. Em conclusão, não foi possível definir com certeza a relação entre as duas patologias no caso aqui apresentado, porém chamou a atenção a melhora dos sintomas neurológicos após o controle da SVCS com o tratamento instituído.The superior vena cava obstruction is a relatively rare condition. We report the case of a 42 year old man suffering of hypertension for about fifteen years. He reported a cervical and thoracic pain for one year, that was related to a 95% of occlusion on the right coronary artery. An angioplasty has been done but the patient still related the thoracic pain. Afterwards the patient had recurrent episodes of right hemiplegia and hypertensive emergencies that have been treated with anti-hypertensive agents. A venous disease was suspected because of cyanosis in the face especially when episodes of transient ischemic attacks occurred. A venography showed obstruction of the right jugular vein near the junction with the superior vena cava. In conclusion, it was not possible to define with certainty the relationship between the two pathologies presented by the patient, even so, we call attention to the improvement of the neurological symptoms after the control of superior vena cava obstruction with the treatment.

Percutaneous placement of bird's nest inferior vena cava filter  

International Nuclear Information System (INIS)

To describe clinical experiences of the use of Bird's Nest inferior vena cava(IVC) filter. Between August 1991 and August 1997, IVC filter was percutaneously inserted in 51 patients with pulmonary embolism(PE) and deep vein thrombosis of the lower extremities. Indications for the placement of this filter were contraindication to anticoagulation in 17 patients, prophylaxis of PE in 17, failed anticoagulation in 11, massive PE with residual floating thrombus in three and complications involving anticoagulation in 3. In order to delineate the location of renal vein and extension of deep vein thrombosis into the IVC, all patients under went inferior vena cavography before filter placement. Thirty filters were inserted through the right femoral vein, 19 through the right internal jugular vein and three through the left femoral vein. The patients involved were followed up for periods ranging from one week to six years (mean 10 months). A Bird's Nest IVC filter was placed in the infrarenal IVC in 44 patients and in the suprarenal IVC in 7. Certain complicatioins ensued. IVC penetration occurred in three patients(5.9%), and in seven(1.37%) the filter wire prolapsed. Except for transient pain, however, there were no serious IVC penetration-related complications and no evidence of recurrence of PE in the cases involving prolapse of the filter wire. During follow up, clinically suspected recurrent PE was noted in two patients(3.9%), but there was no evidence of newly developed occlusion of the IVC. In patients who under went follow up, Bird's Nest IVC filter effectively prevented the development and recurrence of PE, and there were no complications. To prevent of penetration of the IVC and prolapse of the filter, however, technical skill was needed

SISTEMATIZATION OF THE CRANIAL Vena cava IN BUFFALOS (Bubalus bubalis bubalis _ SIMPSON, 1945 SISTEMATIZACIÓN DE LA VENA CAVA CRANEAL EN BÚFALOS (Bubalus bubalis bubalis - SIMPSON, 1945  

Directory of Open Access Journals (Sweden)

Full Text Available The almost complete lack of knowledge of the anatomical characteristics of this race allows us, here, to study the circulatory system in relation to the veined drainage of the large systemic venous trunks _ the cava system. In the literature many reports can be found on the arterial vascular pattern in several areas of the body in domestic animals as well as in savages; conversely, there is a shortage of pertinent data on the veined vascular pattern. For the present work 25 animals were utilized with the object of dissecting and systemizing the vessels, animals were fetuses with ages of between 5 and 9 months, 15 being females and 10 males. In the cranial vena cava the following origin tributaries were observed: External right and left jugular veins and their collateral tributaries; the internal right and left jugular veins; the mediastinial and pericardial; the internal right and left thoracic; thymic; the right and left subclavian and the right and left costocervicalvertebral venous trunk, and occasionally the thoracic duct.Existe un escaso conocimiento de las características anatómicas del sistema circulatorio del búfalo (Bubalus bubalis bubalis con respecto al drenaje venoso de los grandes troncos venosos sistémicos, como el sistema cava.

Side matters: An intriguing case of persistent left superior vena-cava.  

Science.gov (United States)

Persistent left superior vena cava, usually an incidental finding, is the most common thoracic vein anatomical variation draining into the coronary sinus. Central venous catheter procedures may be complicated secondary to the presence of a persistent left superior vena cava, leading to life-threatening complications such as arrhythmias, cardiogenic shock, and cardiac arrest. We present a case of persistent superior vena cava diagnosed on transthoracic echocardiogram (TTE) in a patient with congestive heart failure. A dilated coronary sinus was identified on TTE, followed by injection of agitated saline into the left antecubital vein resulting in filling of the coronary sinus prior to the right atrium-an indication of persistent left superior vena-cava. This also was confirmed on cardiac computed tomography. Such a diagnosis is critical in patients who may undergo central venous catheter procedures such as our patient's potential requirement for an implantable cardiovertor defibrillator due to severe global left ventricular systolic dysfunction. The presence of a persistent left superior vena cava should always be suspected when the guidewire takes a left-sided downward course towards the right atrium at the level of the coronary sinus. Therefore, special attention should be paid to the imaging work-up prior to central venous catheter procedures. PMID:24303491

Obstruction of superior vena cava following the Mustard operation of transposition of great arteries  

International Nuclear Information System (INIS)

The obstruction of the superior vena cava is a frequent late complication of the Mustard operation of the transposition of great arteries. Although it is asymptomatic, it threatens the patient as intracranial hypertension develops. Radionuclide angiocardiography can visualize the collateral blood flow from the obturated vena cava superior by the system of the azygos and hemiazygos veins into inferior vena cava. The benefit of this noninvasive method for screening obstruction was tested in a group of 94 patients. The obstruction of the vena cava superior was apparent in 11 patients (11.7%). In all cases, the diagnosis was confirmed by catheterization and angiocardiography. Pulsed Doppler echocardiography proved an abnormal flow in the vena cava superior in 9 patients. In other five patients with abnormal flow, obstruction was not revealed by radionuclide angiocardiography. Radionuclide angiocardiography supplements echocardiography also as regards other late complications and can be thus recommended for routine examinations of patients after the Mustard operation.

Superior vena cava syndrome in a patient with previous cardiac surgery: what else should we suspect?  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Although mediastinal tumors compressing or invading the superior vena cava represent the major causes of the superior vena cava syndrome, benign processes may also be involved in the pathogenesis of this medical emergency. One of the rarest benign causes is a pseudoaneurysm developing in patients previously having heart surgery. Case report We present the case of a large pseudoaneurysm of the ascending aorta, five years after primary surgery, with a significant compression of the right mediastinal venous system causing superior vena cava syndrome, detected at chest CT angiography. Perioperative findings showed two rush out points both coming from the distal aortic suture line which was performed five years ago. The patient underwent reoperation under circulatory arrest facilitating safe exploration and repair of the distal anastomotic leaks Conclusion Enhanced chest CT should be always undertaken in all patients with superior vena cava syndrome, especially in those previously having cardiac or aortic surgery to correctly evaluate the presence of a pseudoaneurysm. Mass effect to the superior vena cava makes necessary an open surgical treatment of the pseudoaneurysm so as to concurrently resolve the right mediastinal venous system's compression. Surgery should be performed in terms of safe approach to avoid exsanguination and cerebral malperfusion.

CT findings of bilateral inferior vena cava: Differentiation from dilated retroperitoneal veins  

International Nuclear Information System (INIS)

We experience five cases of bilateral inferior vena cava for recent one year. We evaluated the CT findings of the cases and of dilated veins located in the left retroperitoneum (seven left gonadal, seven inferior mesenteric, and two left ascending lumber veins) in the viewpoints of the size, location and relation with the surrounding structures. Bilateral inferior vena cava (IVC) may be asymmetric and the left IVC may be smaller than other retroperitoneal veins with a round contour. The left IVC was located anterior to the spinal body and corresponded with contralateral vena cava in the anteroposterior plane. The gonadal vein was located anterio or anterolateral side of the psoas and always crossed the ureter. Most of the inferior mesenteric vein showed similar location to the opposite site of the vena cava in the anterolateral side of the muscle, medial to the left ureter without crossing. The left ascending lumbar vein was similarly located to the left vena cava but dilated in a short segment. It is required to trace the vessel upward and downward and observe its continuity for correct differentiation. If it is impossible, some differential points suggested in the results of our study will be helpful for distinguishing them

Vena Cava 3D Contrast-Enhanced MR Venography: A Pictorial Review  

International Nuclear Information System (INIS)

Three-dimensional contrast-enhanced magnetic resonance venography (CE MRV) is a sensitive and accurate method for diagnosing vena cava pathologies. The commonly used indirect approach involves a nondiluted gadolinium contrast agent injected into an upper limb vein or, occasionally, a pedal vein for assessment of the superior or inferior vena cava. In our studies, a coronal 3D fast multi-planar spoiled gradient-echo acquisition was used. A pre-contrast scan was obtained to ensure correct coverage of the region of interest. We initiated contrast-enhanced acquisition 15 sec after the start of contrast agent injection and performed the procedure twice. The image sets were obtained during two 20-30-sec breath hold, with a breathing rest of 5-6 sec, to obtain the first-pass and delayed arteriovenous phases. For patients with Budd-Chiari syndrome, a third acquisition coinciding with late venous phase was collected to visualize the hepatic veins, which was carried out by one additional acquisition after a 5-6-sec breathing time. This review describes the clinical application of 3D CE MRV in vena cava congenital anomalies, superior and inferior vena cava syndrome, Budd-Chiari syndrome, peripheral vein thrombosis extending to the vena cava, pre-operational evaluation in portosystemic shunting and post-surgical follow-up, and road-mapping for the placement and evaluation of complications of central venous devices

Sonographic Measurement of the Inferior Vena Cava as A Marker of Blood Loss  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objective: Detecting and monitoring blood loss is always a challenging dilemma in emer-gency settings. Measuring diameter of inferior vena cava in trauma patients may be useful in this regard. This has been classically done with CT; however do-ing it with Ultrasound as a bedside easily available modality is a novel approach. Materials and Methods: Between January 2006 and March 2006, 88 injured patients referred to Namazee Hospital, were investigated. The patients were di-vided in to two groups: a shock group (n=11, 12.5% and a control group (n=77, 87.5% who were trauma patients with normal blood pressure. The maximum antero-posterior diameter of inferior vena cava was measured ultrasonographically both in inspiration and expiration by M-Mode in subxyphoid area. Sta-tistical analysis included tests for normality and cor-relation analysis. Results: The average diameter of inferior vena cava in the control group was 11.2 mm and 9.5mm in expira-tion and inspiration respectively. In contrast the above values were 5.6 and 4.3 mm in shock group. Correlation analysis revealed a negative correlation between the diameter of inferior vena cava and the presence of shock (r=0.61. Conclusion: The diameter of inferior vena cava was found to correlate with shock in trauma patients. This measurement can be added to FAST sonography of trauma patient with minimum additional time.

Simple hepatic cyst causing inferior vena cava thrombus  

Science.gov (United States)

INTRODUCTION Thrombosis of the inferior vena cava (IVC) is governed by Virchow's triad of stasis of blood flow, endothelial damage and hypercoagulability. Causes may be secondary to malignancy, congenital anomalies or other infrequent events such as external compression. We present a case of external compression of the IVC leading to extensive thrombus burden secondary to a benign hepatic cyst. PRESENTATION OF CASE A 72 year old African American female presented to the emergency department with new onset shortness of breath, right lower extremity weakness and swelling. CT imaging demonstrated multiple hepatic cysts compressing the IVC, leading to extensive clot burden. Treatment with heparin drip was initiated without resolution of her symptoms. Transcatheter mechanical thrombectomy and tPA infusion was performed. After 24 h, swelling and weakness were nearly resolved. The patient was bridged to therapeutic low molecular weight heparin in preparation for surgery. DISCUSSION Management of IVC thrombosis has typically been with a heparin drip and transition to oral anticoagulants. Thrombolysis has been shown to promote complete clot lysis more often than compared to standard anticoagulant therapy. In addition, venous patency was better maintained. CONCLUSION We feel that the added benefit of short term effects of improved venous patency and long term benefits of less post thrombotic syndrome, catheter based tPA administration and mechanical thrombectomy for thrombus offers an adjuvant treatment in the setting of large clot burden refractory to standard treatment.

Inferior vena cava filters: what radiologists need to know.  

Science.gov (United States)

Inferior vena cava (IVC) filters are a controversial mechanical adjunct in the prevention of pulmonary embolism, the most serious result of venous thromboembolism. Despite modern IVC filters being in clinical use for more than 45 years, there is still uncertainty amongst many radiologists about the indications for IVC filter placement and their removal, particularly the more recent prophylactic use in patients without confirmed deep vein thrombosis (DVT) or pulmonary embolism (PE). Recently published guidelines on filter use from the National Institute of Health and Clinical Excellence (NICE) and other professional bodies are discussed. The vast majority of IVC filters in the UK are inserted by interventional radiologists, so radiologists may be the first point of contact for information requested by other clinicians. The increasing use of filters means that radiologists will encounter filters increasingly often during abdominal cross-sectional imaging. Awareness of common filter-related complications, such as tilting, thrombosis, and caval perforation, is useful to reassure or alert other clinicians. The potential role of filters in upper extremity DVT and requirement for concomitant anticoagulation is discussed. PMID:23452875

Animal experimental study of safety for a self-made vena cava stent-filter  

International Nuclear Information System (INIS)

Objective: To evaluate the safety of a self-made vena cava stent-filter(VCSF)for prevention of pulmonary embolism. Methods: Fusiform unmhrella-like vena cava filter was made of Nitinol wires and stainless steel metal pole, and then ten mongrel dogs were implanted with these self-made filters and divided into 5 groups according to the different periods (2, 3, 4, 5 and 6 w) of filter placement, with 2 dogs in each group. After the VCSFs were placed in inferior vena cava via the right femoral vein approach, the dogs in each group were bred for 2-6 weeks, respectively. The blood flow of inferior vena cava and the position of the filters were inspected by inferior vena-cavography according to the indwelling periods. Finally the metal pole was retrieved via the femoral vein, leaving the VCSF as permanent venousz stent. The feasibility of retrieval and the free state of filter net with the adhering vascular wall were evaluated. Laparotomies were performed to remove the inferior vena cava from the animals for gross and electron microscopic examinations of the inferior vena cava intimal changes of the involved segment. Results: All 10 VCSFs were placed at the right positions of the dogs successfully. Angiography showed patent inferior vena cava without filter thrombosis at 2-6 weeks. There were no tilting and migration of the filter and all the metal poles were successfully retrieved. The superior and inferior extremities of filter nets could be set free with all the filters turning into venous stents. Postmortem displayed retroperitoneal hemorrhage and caval thrombosis. The barbs of the filters penetrated over the caval adventitial coat. Under electron microscope, a thin layer of neointima already covered the braiding net of VCSFs at 2 weeks after the deployment. The tunica intima became slightly thick at 3-4 weeks and with moderate proliferation at 5-6 weeks. Conclusions: The self-made vena cava stent-filter possesses rather long indwelling period according to the necessity of treatment with simultaneously keeping patent caval flow, stability of the position and easy for displacement and retrieval.

Inferior Vena Cava Filter Placement during Pregnancy: An Adjuvant Option When Medical Therapy Fails.  

Science.gov (United States)

The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive option as prophylaxis for pulmonary embolism during pregnancy. PMID:23781361

Resection of a malignant paraganglioma located behind the retrohepatic segment of the inferior vena cava  

Science.gov (United States)

Background Resection of a retrocaval paraganglioma is technically challenging due to limited tumor accessibility and proximity to the vena cava. Case presentation A large, malignant paraganglioma was found behind the retrohepatic segment of the inferior vena cava of a 60-year-old male. During resection of this rare paraganglioma, the left lateral lobe of the liver, a portion of the caudate lobe of the liver, and the gallbladder were also removed. Unfortunately, the patient died six months after surgery due to hepatic metastasis. Conclusion This case demonstrates that a partial hepatectomy may be necessary to improve tumor accessibility during resection of a retrocaval paraganglioma, particularly if the tumor is proximal to the vena cava. Furthermore, palliative treatments may help prevent tumor recurrence and metastasis of malignant paragangliomas.

[Radical surgical resection of leiomyosarcoma of the inferior vena cava with intracardial tumour growth].  

Science.gov (United States)

Sarcoma of the inferior vena cava (IVC) is a rare clinical entity. Surgical treatment of IVC is associated with improved survival. This case report describes a 42-year-old woman with biopsy-proven leiomyosarcoma of the inferior vena cava with intracardial tumour growth. The primary tumour was only 1 x 1 cm in the wall of the vena cava while the intracaval tumour was 12 cm long with a diameter of 5 cm and 1.5 cm in the right atrium. Using venovenous bypass with circulatory support, the tumour was excised in toto and the caval vein closed with a pericardial patch. The patient was discharged in good condition after 19 days.

Extension of adrenal tumors into the vena cava: results of magnetic resonance angiography  

International Nuclear Information System (INIS)

In rare cases, large adrenal masses with a suspicion of malignancy exhibit tumor extension into the adrenal vein and inferior vena cava. When planning surgery, the relationship of the extension to the inferior vena cava is of decisive improtance. We describe in two cases on the detection of a tumor thrombus in the inferior vena cava arising from a malignant adrenal mass by means of MR angiography (TOF, coronary 2D GRE images [FLASH], 3 slices acquired during 15 second apnea). The angiograms correlated well with the results of DSA venacavography and with the intraoperative findings. Thus, MRA has been demonstrated to be suitable for the certain proof of a venous tumor thrombus not only in cases of renal cell carcinomas but also in cases of malignant adrenal masses. The method should be applied whenever there is evidence of a venous involvement in the adrenal MR images. (orig.)

Diagnosis of tricuspid insufficiency by Doppler flowmetry in the inferior vena cava  

International Nuclear Information System (INIS)

Eighty-five patients subjected to routine heart catheterization were examined with duplex scanning of the inferior vena cava. Adequate Doppler recordings and a right ventricular angiography were obtained in 79 of them. Tricuspid insufficiency was found to be present in 34 patients at angiography and in 24 at duplex examination. No false positive Doppler diagnoses of tricuspid insufficiency occurred. The possibility of false positive angiographic diagnoses is discussed. A high correlation was found between percentage reversed flow in the inferior vena cava during ventricular systole and degree of angiographic tricuspid insufficiency. It is concluded that duplex scanning of the inferior vena cava seems to be a good alternative to angiography in the diagnosis and quantification of tricuspid insufficiency. (orig.)

Evaluation of the superior vena cava system in children with digital subtraction angiography  

Energy Technology Data Exchange (ETDEWEB)

The authors report a new pediatric application of digital subtraction angiography (DSA) that is the evaluation of the superior vena cava system. 22 children have been explored. All of them had a history of previous central venous catheter placement for parenteral nutrition (13), hemodialysis (5), chemotherapy or antibiotic therapy (4). The aim of the examination was to obtain a venous mapping before a new catheter placement (14 cases) or to look for a venous thrombosis origin of superior vena cava syndrom or septicemia (8 cases). Except failure of two examinations because of absence of venous injection site, DSA showed thrombosis of one vein in 7 cases and of multiple veins in 11 cases. A pulmonary embolus was also discovered. The authors conclude that this non invasive method yields very valuable information on superior vena cava system.

Successful implantation of a biventricular pacing and defibrillator device via a persistent left superior vena cava  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Persistent left superior vena cava is the most common thoracic venous abnormality which is usually asymptomatic, found incidentally during pacemaker implantation. The main problem is related to reaching the appropriate pacing site and ensuring stable lead placement. Case report. We reported a successful implantation of a biventricular pacing and defibrillator device (CRT-D via a persistent left superior vena cava in a 55-year-old man with dilated cardiomyopathy and severe heart failure. A persistent left superior vena cava was detected during CRT-D implantation. We managed to position electrodes in the right ventricular outflow tract, a posterior branch of the coronary sinus and in the right atrium. Conclusion. Congenital anomalies of thoracic veins may complicate lead placement on the appropriate and stable position. The presented case demonstrates a successful biventricular pacing and defibrillator therapy device implantation in a patient with dilated cardiomyopathy and severe heart failure.

Congenital anomalies of the inferior vena cava: importance of multiplanar imaging methods: an iconographic essay  

International Nuclear Information System (INIS)

The inferior vena cava is the result of a complex embryologic process which takes place between 6 and 8 weeks of intra-uterine life. Several variations can occur during this process, and a defective embryogenesis of this vessel may lead to the development of anatomic variants. Although many of these variants are asymptomatic, the radiologist should be aware of them and of the potential medico-legal issues involved, especially in cases in which abdominal surgery or hemodynamic procedures are contemplated. In this paper, the major congenital anomalies involving the inferior vena cava are reviewed under the form of a pictorial essay, highlighting the role of the multiplanar imaging methods (volumetric computed tomography and magnetic resonance imaging) in their diagnosis.

Angiography of azygos continuation of inferior vena cava in situs ambiguus with left isomerism (polysplenia syndrome)  

Energy Technology Data Exchange (ETDEWEB)

We have in our records 11 patients with situs ambiguus and left isomerism (polysplenia). Ten had an interruption of the inferior vena cava (IVC) with azygos continuation; in eight cases the continuation was to the left superior vena cava (LSVC), in one case to the right superior vena cava (RSVC) and in one case to both the LSVC and RSVC. Two patients underwent surgical correction by a buffle procedure of the functioning single atrium. The angiographic confirmation of the azygos system anatomy is important in planning the surgical correction of patients with left isomerism. Clinically, given the same heart defects with normal pressures, the rightsided drainage is probably more favorable, producing less peripheral desaturation.

Segmental variants of the inferior vena cava - typical findings correlated with embryological development for differential diagnosis; Segmentale Varianten der Vena cava inferior - Erscheinungsbild mit embryologischer Korrelation in Abgrenzung zum sekundaeren Vena-cava-Verschluss  

Energy Technology Data Exchange (ETDEWEB)

The vast variability of the overall rare congenital anomalies of the inferior vena cava (IVC) are mostly detected by accident through different imaging modalities. These cannot be classed as pathological findings, and should not be confused with lymphomas and has to differ from secondary collateral venous pathways. Based on 656 CT examinations 10.5% known forms of IVC anomalies were found. According to the embryological development three main groups of IVC variants could be nosologically classified: agenesis of the suprarenal IVC, anomalies of the pars renalis and anomalies of the infrarenal IVC. Additionally three unusual anomaly complexes were found. For the understanding details of the embryology based on a simplified depiction are presented. (orig.) [German] Die grosse Variabilitaet der als insgesamt selten anzusehenden angeborenen Venenanomalien der Vena cava inferior werden meist zufaellig durch verschiedene bildgebende Untersuchungsverfahren entdeckt.

Retro-aortic left renal vein with left suprarenal vein draining into inferior vena cava  

Directory of Open Access Journals (Sweden)

Full Text Available During a routine undergraduate dissection of abdomen of a 50-year-old male cadaver, a variant pattern of left renal and suprarenal veins was encountered. The left renal vein coursed behind the aorta to drain into inferior vena cava at the level of lower pole of left kidney. The left suprarenal vein coursed in front of aorta to drain directly into inferior vena cava instead of left renal vein. A knowledge of such patterns is important for renal surgeons operating for renal transplantation, renal trauma and nephrectomy. Further the ontogenic basis and clinical implications of the anomalies are discussed in the detail.

Testicular tumors with tumor thrombosis within the inferior vena cava: Two case reports  

Energy Technology Data Exchange (ETDEWEB)

Testicular tumors are almost all malignant tumors and can develop in younger age groups. Testicular tumors are mostly curable, with reported cases of tumor thrombosis within the inferior vena cava being rare. Two patients, aged 35 years and 37 years old complaining of testicular pain and lower abdominal pain were diagnosed with testicular tumors by ultrasound. In addition, tumor thrombus of the inferior vena cava was diagnosed concomitantly at the time of the diagnosis by computed tomography and magnetic resonance imaging. Here, we report testicular tumors accompanied by tumor thrombus, which is an extremely rare finding, with limited reports available. Pathologic diagnoses were seminoma and mixed germ cell tumors, respectively.

Hepatic Veins and Inferior Vena Cava Thrombosis in a Child Treated by Transjugular Intrahepatic Portosystemic Shunt  

International Nuclear Information System (INIS)

We report the case of a 9-year-old boy with portal hypertension, due to Budd-Chiari syndrome, and retrohepatic inferior vena cava thrombosis, submitted to a transjugular intrahepatic portosystemic shunt (TIPS) by connecting the suprahepatic segment of the inferior vena cava directly to the portal vein. After 3 months, the withdrawal of anticoagulants promoted the thrombosis of the TIPS. At TIPS revision, thrombosis of the TIPS and the main portal vein and clots at the splenic and the superior mesenteric veins were found. Successful angiography treatment was performed by thrombolysis and balloon angioplasty of a severe stenosis at the distal edge of the stent.

Inferior vena cava CT pseudothrombus produced by rapid arm-vein contrast infusion  

Energy Technology Data Exchange (ETDEWEB)

Laminar flow within the inferior vena cava can cause artifacts that may simulate thrombus if a foot-vein infusion is used. A pseudothrombus artifact within the suprarenal inferior vena cava produced by rapid infusion of contrast material through an arm vein is reported. This artifact wasa noted in 25 patients in a 6 month period and was believed to be from laminar flow of renal venous effluent of increased opacity around less opacified infrarenal caval contents. Differentiation from true thrombus can be made by the use of delayed scans as well as the increased density and relatively poor margination of the artifact.

Reevaluation of transthoracic fine needle aspiration biopsy in diagnosing superior vena cava syndrome  

Energy Technology Data Exchange (ETDEWEB)

Superior vena cava syndrome has various aetiologies but in the majority of cases it is caused by a malignant mass. Assessment of the underlying pathology as rapidly and reliably as possible is very important for proper therapy management. Dynamic computed tomography examination of the chest can differentiate patients in whom superior vena cava obstruction is caused by a mass, from those with a vascular aetiology. In patients with a mass, fine needle aspiration biopsy guided by the computed tomographic examination may provide cytological diagnosis in a fast and well tolerated manner.

Percutaneous retrieval of a vena cava filter from the right atrium: case report  

International Nuclear Information System (INIS)

Migration of vena cava filters can occur spontaneously, but it can also occur as a result of entanglement of the filter with a guidewire, particularly during 'blind' (unguided) insertion of a central venous line. When a filter migrates to the heart, traditional practice has been either to leave the filter in place or to remove it surgically by means of open heart surgery and cardiopulmonary bypass. We found only 6 reports of successful percutaneous retrieval or repositioning of a vena cava filter (Table 1). We describe a new interventional technique for retrieving a filter from the right atrium and a novel endosurgical method for removing a filter from the innominate vein. (author)

Liver trauma and transection of the inferior vena cava; Sentinel contrast sign and hepatic perivenous tracking  

Energy Technology Data Exchange (ETDEWEB)

CT of a child with severe liver trauma due to a seat belt injury demonstrated avulsion of a portion of the lateral segment of the left lobe of the liver. The location of nondependent extravasated contrast material aided in identification of the visceral fracture site (the sentinel contrast sign). Associated transection of the inferior vena cava was evidenced by hypoatenuating zones adjacent to all the major hepatic veins and vena cava (hepatic perivenous tracking). Recognition of these two signs is important so that the radiologist can help the surgeon select the optimal operative approach. (orig.).

Thermoregulatory catheter-associated inferior vena cava thrombus.  

Science.gov (United States)

The use of thermoregulatory catheters (TRCs) in critically ill patients has become increasingly popular. TRCs have been shown to be effective in regulating patient body temperature with improved outcomes. Critically ill patients, especially multitrauma patients and those with femoral catheters, are at high risk for deep vein thrombosis (DVT). Among patients for whom chemical DVT prophylaxis is not an option, inferior vena cava (IVC) filters are often placed prophylactically. The development of intravascular ultrasound (IVUS) has allowed placement of IVC filters at the bedside for patients who are too ill for transport to the operating room or cardiac catheterization lab. After encountering several patients with occult DVT of the IVC during bedside IVC filter placement, we performed a retrospective review to determine the incidence of DVT or pulmonary embolus (PE) in patients who had been treated with a TRC at Baylor University Medical Center at Dallas. Since 2008, IVC filters have been deployed at the bedside with the use of IVUS at Baylor University Medical Center. During that same time period, 83 patients had a TRC placed for either intravascular warming or cooling during their resuscitation. Forty-seven out of 83 patients who had a TRC placed survived their injuries. Ten of 47 patients (21%) were diagnosed with DVT or PE, and 6 of these 10 (60%) were found to have caval thrombus. We present this case series as evidence that undiagnosed IVC thrombus associated with TRCs may be higher than previously suspected, given that 5 out of 10 patients who had IVUS of their IVC for prophylactic IVC filter placement, as well as one patient diagnosed with PE, were found to have caval thrombus.

Retrievable Inferior Vena Cava Filters: Factors that Affect Retrieval Success  

Energy Technology Data Exchange (ETDEWEB)

Purpose: To report and analyze the indications, procedural success, and complications of retrievable inferior vena cava filters (rIVCF) placement and to identify parameters that influence retrieval attempt and failure. Methods: Between January 2005 and December 2010, a total of 200 patients (80 men, median age 67 years, range 11-95 years) received a rIVCF with the clinical possibility that it could be removed. All patients with rIVCF were prospectively entered into a database and followed until retrieval or a decision not to retrieve the filter was made. A retrospective analysis of this database was performed. Results: Sixty-one percent of patients had an accepted indication for filter placement; 39% of patients had a relative indication. There was a tendency toward a higher retrieval rate in patients with relative indications (40% vs. 55%, P = 0.076). Filter placement was technically successful in all patients, with no procedure-related mortality. The retrieval rate was 53%. Patient age of >80 years (odds ratio [OR] 0.056, P > 0.0001) and presence of malignancy (OR 0.303, P = 0.003) was associated with a significantly reduced probability for attempted retrieval. Retrieval failure occurred in 7% (6 of 91) of all retrieval attempts. A time interval of > 90 days between implantation and attempted retrieval was associated with retrieval failure (OR 19.8, P = 0.009). Conclusions: Patient age >80 years and a history of malignancy are predictors of a reduced probability for retrieval attempt. The rate of retrieval failure is low and seems to be associated with a time interval of >90 days between filter placement and retrieval.

A time interval of > 90 days between implantation and attempted retrieval was associated with retrieval failure (OR 19.8, P = 0.009). Conclusions: Patient age >80 years and a history of malignancy are predictors of a reduced probability for retrieval attempt. The rate of retrieval failure is low and seems to be associated with a time interval of >90 days between filter placement and retrieval.

Adjunctive Inferior Vena Cava Filter Placement for Acute Pulmonary Embolism  

International Nuclear Information System (INIS)

Inferior vena cava (IVC) filters are sometimes placed as an adjunct to full anticoagulation in patients with significant pulmonary embolism (PE). We aimed to determine the prevalence of adjunctive IVC filter placement in individuals diagnosed with PE, as well as the effect of adjunctive filter placement on mortality in patients with right heart strain associated with PE. This was a retrospective study of patients with acute PE treated with full anticoagulation admitted to a single academic medical center. Information abstracted from patient charts included presence or absence of right heart strain and of deep-vein thrombosis, and whether or not an IVC filter was placed. The endpoint was in-hospital mortality. Over 2.75 years, we found that 248 patients were diagnosed with acute PE, with an in-hospital mortality rate of 4.4%. The prevalence of adjunctive IVC filter placement was 13.3% (33 of 248), and the prevalence of documented right heart strain was 27.0% (67 of 248). In-hospital mortality was 10.2% in the non-filter-treated group (5 of 49), whereas there were no deaths in the filter-treated group (0 of 18); however, the difference was not statistically significant (P = 0.37). Both the presence of deep-vein thrombosis and of right heart strain increased the likelihood that an adjunctive IVC filter was placed (P < 0.0001 and P < 0.001, respectively). At our institution, patients were treated with IVC filters in addition to anticoagulation in 13.3% of cases of acute PE. Prospective studies or large clinical registries should be conducted to clarify whether this practice improves outcomes.

An applied anatomical study of the ostia venae hepaticae and the retrohepatic segment of the inferior vena cava.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In sixty normal adult livers the retrohepatic segment of the inferior vena cava was found mostly to assume a curve to the left (75.00%). This segment has a length of 7.1 cm and is totally encircled by liver substance in 6.67% of cases. Altogether 492 ostia venae hepaticae were studied, averaging 8.2 per liver and classified as large, medium and small. The large ostia are divided into superior (SLO) and inferior (ILO) openings. The SLO are found opening into the upper end of the hepatic segmen...

Massive venous thrombosis of inferior vena cava as primary manifestation of renal Ewing's sarcoma.  

Science.gov (United States)

We report an extraordinarily rare case of a 17-year-old male with an extraskeletal Ewing's sarcoma (ESS) of the kidney and a massive thrombosis involving the inferior vena cava (IVC), from the iliac axis to the right atrium. This onset resembled renal cell carcinoma (RCC), although histological examination revealed it was an extraskeletal Ewing's sarcoma/peripheral neuro-ectodermal tumor (EES/PNET). EES/PNET should benefit from neoadjuvant chemotherapy to reduce the risk of metastasis and of recurrent disease due to delay in suitable treatment. Therefore, in the presence of a renal mass with tumor extension of IVC, it is reasonable to bear in mind that other tumors, apart from RCC, could occur. In such cases, a US or CT-scan guided biopsy could be useful. PMID:21612762

Tumor renal con trombo en la vena cava inferior: Manejo quirúrgico y pronóstico / Renal tumor with inferior vena cava thrombus: Surgical approach and prognosis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivos: el objetivo del presente estudio fue evaluar las estrategias usadas para el manejo quirúrgico del cáncer de renal con extensión de trombo a la vena cava inferior y evaluar el pronóstico del paciente. Métodos: Quince pacientes con cáncer renal y trombo en la vena cava inferior fueron somet [...] idos a una nefrectomía radical y trombectomía y fueron evaluados de forma retrospectiva. Los pacientes fueron seguidos desde 0 a 36 meses (media de 9,5 meses). La tomografía computada con reconstrucción tridimensional fue usada para definir el nivel del trombo. Resultados: La edad media fue de 54 años, con un rango de entre 16 y 79 años. El trombo fue clasificado como de nivel I (13,5%), nivel II (40%), nivel III (26,5%) y nivel IV (20%). La cirugía fue llevada a cabo mediante by pass cardiopulmonar en seis casos, tres de los cuales sin esternotomía. Hubo una muerte intraoperatoria (13%) en un paciente que presentaba enfermedad metastásica con un trombo que alcanzaba la aurícula derecha. Los pacientes con ganglios positivos o enfermedad metastásica como presentación inicial tenían peor supervivencia global en la curva de Kaplan-Meier. Ambos, estadiaje tumoral (p = 0,380), y extensión del trombo (p = 0,174) no tuvieron relación con la supervivencia. Conclusiones: A pesar de su morbilidad y mortalidad, la nefrectomía radical y la trombectomía deberían ser llevadas a cabo en casos de carcinoma renal con trombo tumoral, porque puede ofrecer la posibilidad de control local de la enfermedad. Los pacientes con ganglios linfáticos y enfermedad metastásica tienen peor pronóstico. Abstract in english Objectives: The aim of this study was to evaluate strategies used for surgical management of renal cell carcinoma with tumoral thrombus extension in the inferior vena cava (IVC) and evaluate patient's prognosis. Metods: Fifteen patients with renal tumor and IVC thrombus, underwent radical nephrectom [...] y and thrombectomy, and were retrospectively evaluated. Patients were followed for 0 to 36 months (mean of 9.5 months). Computed tomography (CT) scan with three-dimensional reconstruction was used to define IVC thrombus level. Results: The mean age was 54 years, range from 16 to 79. The thrombus was classified as level I - 13.5%, level II - 40%, level III - 26.5% and level IV - 20%. Surgery was performed with cardiopulmonary bypass (CPB) in six (40%) cases, three (50%) without sternotomy. There was one (13%) death during the intraoperative period; this patient presented extensive metastatic tumor, with the thrombus reaching the right atrium. Patients with lymph node or metastatic disease at initial presentation had poorer overall survival in Kaplan-Meier curve. Both, tumor stage (p = 0.380), and thrombus extension (p = 0.174) were not related to survival. Conclusions: Despite its morbidity and mortality, radical nephrectomy with thrombectomy should be performed in case of renal cell carcinoma with tumoral thrombus, because it can offers the possibility of local control. Patients with lymph node and distant metastatic disease have poor prognoses.

Design Optimization of Vena Cava Filters: An application to dual filtration devices  

Energy Technology Data Exchange (ETDEWEB)

Pulmonary embolism (PE) is a significant medical problem that results in over 300,000 fatalities per year. A common preventative treatment for PE is the insertion of a metallic filter into the inferior vena cava that traps thrombi before they reach the lungs. The goal of this work is to use methods of mathematical modeling and design optimization to determine the configuration of trapped thrombi that minimizes the hemodynamic disruption. The resulting configuration has implications for constructing an optimally designed vena cava filter. Computational fluid dynamics is coupled with a nonlinear optimization algorithm to determine the optimal configuration of trapped model thrombus in the inferior vena cava. The location and shape of the thrombus are parameterized, and an objective function, based on wall shear stresses, determines the worthiness of a given configuration. The methods are fully automated and demonstrate the capabilities of a design optimization framework that is broadly applicable. Changes to thrombus location and shape alter the velocity contours and wall shear stress profiles significantly. For vena cava filters that trap two thrombi simultaneously, the undesirable flow dynamics past one thrombus can be mitigated by leveraging the flow past the other thrombus. Streamlining the shape of thrombus trapped along the cava wall reduces the disruption to the flow, but increases the area exposed to abnormal wall shear stress. Computer-based design optimization is a useful tool for developing vena cava filters. Characterizing and parameterizing the design requirements and constraints is essential for constructing devices that address clinical complications. In addition, formulating a well-defined objective function that quantifies clinical risks and benefits is needed for designing devices that are clinically viable.

Leiomioma benigno metastatizante de veia cava inferior: rara complicação tardia de histerectomia Benign metastasizing leiomyoma of inferior vena cava: a rare condition following hysterectomy  

Directory of Open Access Journals (Sweden)

Full Text Available Large vessel tumors diagnosis is usually difficult. Benign metastasizing leiomyoma is a rare condition occurring inside peripheral vessels. There are few publications about this tumor inside inferior vena cava. A 54 years old female patient is presented with a previous hysterectomy for myomas. She complained of no specific symptoms 18 months after surgery. Computer tomography revealed a 7.5 x 3.5 x 4.0 cm mass at inferior vena cava and right psoas muscle. After surgical management and immunohistochemical screening biopsy, the diagnosis was benign metastasizing leiomyoma of inferior vena cava. The patient recovery was uneventful. Benign metastasizing leiomyoma of inferior vena cava is a very rare condition, and must be suspected in patients with primary leiomyosarcoma, especially in women previously submitted to hysterectomy for leiomyomatosis.

Long-term follow-up of protection efficacy of vena cava filters in the prevention of pulmonary embolism  

International Nuclear Information System (INIS)

Objective: To analyze the protection efficacy of the vena cava filter from pulmonary thromboembolism and report the problems and complications after filter placement. Methods: Fifty-five Vena Tech-LGM filters (VTF) and 6 Titanium-Greenfield filters (TGF) were placed in 61 patients. Follow-up was obtained by means of duplex sonography of the inferior vena cava and abdominal radiography in 38 patients, and by means of computed tomography in 11 patients. Results: One case of pulmonary embolism was seen following filter placement. Filter thrombosis occurred in 9 cases. There had been 1 case of incomplete filter opening and one case of filter tilting. Filter migration was noted in 1 case. Conclusion: This experience suggests that vena cava filter is safe and effective for the prevention of pulmonary embolism. A vena cava filter should only be inserted in a patient when there is strict proof of the indication

The clinical application of the implantation of retrievable filters in superior vena cava  

International Nuclear Information System (INIS)

Objective: To investigate the safety of the placement of Tulip retrievable filter in superior vena cava and to discuss the prevention of pulmonary embolism (PE). Methods: Implantation of Tulip retrievable filter in superior vena cava was performed in ten patients (6 males and 4 females, aged 42-60 years) with acute or subacute deep venous thrombosis in upper extremity or cephalo-cervical region. After the placement of filter, the local via-catheter thrombolysis was conducted. The clinical results, such as the improvement of venous obstructed symptoms at upper extremity or cephalo-cervical region, were recorded. The filter's shape and location were checked. The possible occurrence of pulmonary embolism was observed. Results: The filter was successfully implanted in supper vena cava in all patients, and the deep venous thrombosis at upper extremity and cephalo-cervical region responded well to the local via-catheter thrombolysis. The filters showed no displacement or tilting. The swelling at upper extremity and cephalo-cervical region was markedly faded away. No symptomatic pulmonary embolism occurred. the filter was successfully retrieved via the femoral vein in four patients. Conclusion: Tulip filter can be safety implanted in superior vena cava and can be smoothly retrieved. The occurrence of pulmonary embolism can be effectively prevented if corresponding local via-catheter thrombolysis is carried out. (authors)

Klippel-Trenaunay syndrome with gastrointestinal bleeding, splenic hemangiomas and left inferior vena cava  

Directory of Open Access Journals (Sweden)

Full Text Available Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins, cutaneous capillary malformation, and hypertrophy of bone and (or soft tissue. Gastrointestinal vascular malformations in Klippel-Trenaunay syndrome may present with gastrointestinal bleeding. The majority of patients with spleenic hemangiomatosis and/or left inferior vena cava are asymptomatic. We herein report a case admitted to the gastroenterology clinic with life-threatening hematochezia and symptomatic iron deficiency anemia. Due to the asymptomatic mild intermittent hematochezia, splenic hemangiomas and left inferior vena cava, the patient did not seek any help for gastrointestinal bleeding until his admittance to our department for evaluation of massive gastrointestinal bleeding. He was referred to angiography because of his serious pathogenetic condition and inefficiency of medical therapy. The method showed that hemostasis was successfully achieved in the hemorrhage site by embolism of corresponding vessels. Further endoscopy revealed vascular malformations starting from the stomach to the descending colon. On the other hand, computed tomography revealed splenic hemangiomas and left inferior vena cava. To the best of our knowledge, this is the first Klippel-Trenaunay syndrome case presenting with gastrointestinal bleeding, splenic hemangiomas and left inferior vena cava. The literature on the evaluation and management of this case is reviewed.

Right lung upper lobe carcinoma radical excision plus superior vena cava angioplasty.  

Science.gov (United States)

An elderly male patient was found to be with "nodule in upper lobe of right lung" during his health examination, although without any symptom. Chest CT at admission showed that the nodules were close to the superior vena cava, and CT reconstruction displayed an adipose space between the nodules and the superior vena cava. However, bronchoscopy showed negative results. Pre-operative exploration showed that the right upper lung nodules were tightly attached to the surface of superior vena cava and could not be effectively divided; an invasion could not be ruled out. The surgery was performed in a distal-proximal manner. The pulmonary fissure, bronchi, and arteries were divided firstly, followed by veins and the surrounding tissues of the lung. After the surrounding spaces of the tumor were sufficiently disassociated, superior vena cava angioplasty was performed using a stapler. The surgery was performed completely under thoracoscopy, during which the surgical incision was not enlarged. The main operation port was about 4 cm in diameter. Two axillary operation ports (about 1.2 and 0.6 cm in diameter, respectively) were also used. All the surgical equipment were used smoothly, and thus the surgery was completed with lowest invasion.

'RecoveryTM' Vena Cava Filter: Experience in 96 Patients  

International Nuclear Information System (INIS)

The purpose of the study was to assess the clinical safety and efficacy of the 'RecoveryTM' (Bard) inferior vena cava (IVC) filter. We retrospectively evaluated the clinical and imaging data of patients who had a 'RecoveryTM' IVC filter placed between January 2003 and December 2004 in our institution. The clinical presentation, indications, and procedure-related complications during placement and retrieval were evaluated. Follow-up computed tomography (CT) examinations of the abdomen and chest were evaluated for filter-related complications and pulmonary embolism (PE), respectively. 'Recovery' filters were placed in 96 patients (72 males and 24 females; age range: 16-87 years; mean: 46 years). Twenty-four patients presented with PE, 13 with deep vein thrombosis (DVT) and 2 with both PE and DVT. The remaining 57 patients had no symptoms of thromboembolism. Indications for filter placement included contraindication to anticoagulation (n = 27), complication of anticoagulation (n = 3), failure of anticoagulation (n = 5), and prophylaxis (n = 61). The device was successfully deployed in the infrarenal (n = 95) or suprarenal (n = 1) IVC through a femoral vein approach. Retrieval was attempted in 11 patients after a mean period of 117 days (range: 24-426). The filter was successfully removed in nine patients (82%). Failure of retrieval was due to technical difficulty (n = 1) and the presence of thrombus in the filter (n = 1). One of the nine patients who had the filter removed developed IVC thrombus after retrieval and another had an intimal tear of the IVC. Follow-up abdominal CT (n = 40) at a mean of 80 days (range: 1-513) showed penetration of the IVC by the filter arms in 11, of which 3 had fracture of filter components. In one patient, a broken arm migrated into the pancreas. Asymmetric deployment of the filter legs was seen in 12 patients and thrombus within the filter in 2 patients. No filter migration or caval occlusion was encountered. Follow-up chest CT (n = 27) at a mean of 63 days (range: 1-386) showed PE in one patient (3%). During clinical follow-up, 12 of 96 patients developed symptoms of PE and only 1 of the 12 had PE on CT. There was no fatal pulmonary embolism in our group of patients following 'Recovery' filter placement. However, the current version of the filter is associated with structure weakness, a high incidence of IVC wall penetration, and asymmetric deployment of the filter legs

Case presentation For evaluation of portal hypertension in a 72-year-old Caucasian man without liver cirrhosis, magnetic resonance imaging with gadolinium contrast-enhancement was performed and demonstrated a missing inferior vena cava. A blood return from the lower extremities was shown through enlarged collateral veins of the abdominal wall, vena azygos and hemiazygos continuation, and multiple liver veins emptying into the right cardiac atrium. We describe a rare case of abdominal subcutaneous wall veins as collaterals caused by a congenitally absent infrarenal inferior vena cava with preservation of a hypoplastic suprarenal segment. Conclusion Knowledge of these congenital variations can be of clinical importance and it is imperative for the reporting radiologist to identify these anomalies as they can have a significant impact on the clinical management of the patient.

Full Text Available A persistência de veia cava superior esquerda com ausência da veia cava superior é uma anomalia rara, principalmente quando associada a bloqueio atrioventricular de 3º grau. Relatamos o caso de uma paciente, na qual durante implante de marca-passo definitivo, para a correção de bloqueio atrioventricular total, foi detectada presença de veia cava superior esquerda com suspeição de ausência de veia cava superior, o que levou ao emprego de técnica diferenciada para fixação do eletrodo ventricular. Para confirmação da provável agenesia, foram realizados diversos exames complementares de imagem, demonstrando-se a dificuldade no diagnóstico da síndrome aqui descrita.The superior left vena cava with the absent superior vena cava is a rare abnormality, especially when associated with total heart block. We report a case of a patient in which the presence of superior left vena cava and the absence of the superior vena cava was detected during the implantation of a pacemaker for the correction of a total heart block, which led us to use a different technique for the fixation of the ventricular electrode. To confirm the supposed absence, several image exams were made showing the difficulty on the diagnosis of the described syndrome.

Three-Dimensional Rotational Angiography of the Inferior Vena Cava as an Adjunct to Inferior Vena Cava Filter Retrieval  

International Nuclear Information System (INIS)

The objective of this study was to explore the role of three-dimensional (3-D) rotational angiography (RA) of the inferior vena cava (IVC; 3-D CV) before filter retrieval and its impact on treatment planning compared with standard anteroposterior cavography (sCV). Thirty patients underwent sCV and 3-D CV before IVC filter retrieval. Parameters assessed were: projection of filter arms or legs beyond the caval lumen, thrombus burden within the filter and IVC, and orientation of the filter within IVC. Skin and effective radiation doses were calculated. Statistical analysis was performed using paired Student t test and nonparametric McNemar's test. Standard anteroposterior cavography detected 49 filter arms or legs projecting beyond the caval lumen in 25 patients. Three-dimensional CV demonstrated 89 filter arms or legs projecting beyond the caval lumen in 28 patients. Twenty-two patients had additional filter arms or legs projecting beyond the caval lumen detected on 3-D CV that were not detected on sCV (p < 0.001). Filter apex tilt detection differed significantly (p < 0.001) between sCV and 3-D CV, with 3-D CV being more accurate. The filter apex abutted the IVC wall in 10 patients (33%) on 3-D CV, but this was diagnosed in only 3 patients (10%) with sCV. Thrombus was detected in 8 patients (27%), 1 thrombus of which was seen only on 3-D CV, and treatment was changed in this patient because of thrombus size. Mean effective radiation doses for 3-D CV were approximately two times higher than for sCV (1.68 vs. 0.86 mSv), whereas skin doses were three times lower (12.87 vs. 35.86 mGy). Compared with sCV, performing 3-D CV before optional IVC filter retrieval has the potential to improve assessment of filter arms or legs projecting beyond the caval lumen, filter orientation, and thrombus burden.

Terapia de resincronización cardiaca en paciente con vena cava superior izquierda persistente: Caso clínico Placement of a biventricular resynchronization device in a patient with a persistent left superior vena cava: Report of one case  

Directory of Open Access Journals (Sweden)

Full Text Available Persistent left superior vena cava is the most common venous congenital malformation and is usually asymptomatic. Its presence could increase the difficulty for transvenous lead implantation. We report a 71-year-old woman with an idiopathic dilated cardiomyopathy, atrial fibrillation and heart failure that required biventri-cular resynchronization therapy. During the placement of the device a persistent left superior vena cava was detected. The device was placed without problems and the patient had a satisfactory postoperative evolution.

Thrombosis of the ileo-caval sector: puerperal thrombosis and agenesia thrombosis of the inferior vena cava  

International Nuclear Information System (INIS)

The thrombosis of the inferior vena cava account for around the 15% of the cases of deep venous thrombosis. This is the case of a puerperal primigravida with a cesarean section labor presenting with a thrombosis initially in the right ovarian vein and then extension to the inferior vena cava. Treatment included low molecular weight heparin in anticoagulant doses; rest with elevation of the extremities and elastic bandage. After a satisfactory process evolution with partial lysis of the thrombus, the oral anticoagulation with Acenocumarol for 6 months was started. The second patient, a man aged 73 with backgrounds of an operated hepatic hydatidosis, had a thrombosis of the infrarenal inferior vena cava and agenesia of retrohepatic segment of the inferior vena cava. The patient remains with anticoagulant treatment including Acenocumarol, elastic bandage and hygienic care. As sequela he had a postphlebitic syndrome and reworsening of the edema leading to its admission in two occasions.(author)

Percutaneous transfemoral placement of inferior vena cava filter to prevent pulmonary embolism in patients with malignant tumor  

International Nuclear Information System (INIS)

Objective: To evaluate the effectiveness and safety of inserting an inferior vena cava filter to prevent the pulmonary embolism (PE) due to detachment of the thrombus in the lower extremities. Methods: Inferior vena cava filter were placed in 37 patients with malignant tumor and deep venous thrombosis from 1998 to 2004. Malignancy was confirmed by pathological or cellular biological examination in all cases. The episode of pulmonary embolism was monitored during a post-intervention follow-up. Results: All the filters were placed in the inferior vena cava safely via a percutaneous femoral venous access. No serious complications such as pulmonary embolism occurred during the follow-up periods. Conclusion: The inferior vena cava filter placement is an effective and safe procedure in preventing the pulmonary embolism in patients with malignant tumor and deep venous thrombosis. (authors)

In Vitro Evaluation of a Rheolytic Thrombectomy System for Clot Removal from Five Different Temporary Vena Cava Filters  

International Nuclear Information System (INIS)

Purpose: To evaluate the feasibility of thrombus removal from temporary vena cava filters using a rheolytic thrombectomy device and to assess the embolization rate of this procedure. Methods: Five temporary vena cava filters together with porcine thrombi were placed in a vena cava flow model (semitranslucent silicone tube of 23 mm diameter, pulsatile flow at a mean flow rate of 4 L/min). A rheolytic thrombectomy system (Hydrolyser) was used with a 9 Fr guiding catheter to remove the clots. The effluent was passed through filters of different size and the amount of embolized particles as well as the remaining thrombus were measured. Results: Thrombus removal rates ranged from 85% to 100%. Embolization rates between 47% and 60% were calculated for the different filters. Conclusion: The Hydrolyser is able to remove sufficiently high amounts of thrombus from temporary vena cava filters. However, the amount of embolized particles makes it impossible to utilize this method without special precautions against embolization

Energy Technology Data Exchange (ETDEWEB)

Duplications of the inferior vena cava (IVC) are rare variants of the abdominal vessels and are normally located on both sides of the abdominal aorta. The rare case of a rightsided infrarenal duplication of the IVC with involvement of the common iliac vein is reported. Details of the embryology are presented for the understanding of this IVC variant. The spiral CT with multiplanar reconstructions makes it possible to define the vascular morphology and to differentiate it from lymphoma. (orig.)

Curative resection and reconstruction of the inferior vena cava after extensive infiltration with low-grade endometrial stromal sarcoma.  

Science.gov (United States)

Endometrial stromal sarcoma (ESS) rarely infiltrates the great vessels. We report a successful surgical resection of the inferior vena cava (IVC) after extensive infiltration with metastatic low-grade ESS. A case of presumed recurrence of low-grade ESS demonstrated complete IVC occlusion from tumour thrombus with extensive local disease. Radical resection of the tumour and caval reconstruction was performed. The IVC graft was thrombosed at short-term follow-up. Curative resection of extensive caval infiltration with metastatic low-grade ESS can be achieved. Caval reconstructive procedures may be redundant in the presence of an adequate collateral circulation. PMID:22368192

Congenital inferior vena cava anomalies: a review of findings at multidetector computed tomography and magnetic resonance imaging  

Energy Technology Data Exchange (ETDEWEB)

Inferior vena cava anomalies are rare, occurring in up to 8.7% of the population, as left renal vein anomalies are considered. The inferior vena cava develops from the sixth to the eighth gestational weeks, originating from three paired embryonic veins, namely the subcardinal, supracardinal and postcardinal veins. This complex ontogenesis of the inferior vena cava, with multiple anastomoses between the pairs of embryonic veins, leads to a number of anatomic variations in the venous return from the abdomen and lower limbs. Some of such variations have significant clinical and surgical implications related to other cardiovascular anomalies and in some cases associated with venous thrombosis of lower limbs, particularly in young adults. The authors reviewed images of ten patients with inferior vena cava anomalies, three of them with deep venous thrombosis. The authors highlight the major findings of inferior vena cava anomalies at multidetector computed tomography and magnetic resonance imaging, correlating them the embryonic development and demonstrating the main alternative pathways for venous drainage. The knowledge on the inferior vena cava anomalies is critical in the assessment of abdominal images to avoid misdiagnosis and to indicate the possibility of associated anomalies, besides clinical and surgical implications.

[Compression of the inferior vena cava with thrombus: a rare complication of solitary liver cyst].  

Science.gov (United States)

Because of the increase of ultrasonographic exams, nonparasitic cyst of the liver is frequently encountered. Some giant cysts have complications. The surgical treatment for complicated forms consists in resection of the protruding part. We report a case of a giant non parasitic cyst of the liver which was responsible of a compression of the inferior vena caval with thrombus. The resection of the thrombus was performed after a double control of the vena cava and a control of the aorta. The fenestration of the cyst was performed in a second time. PMID:12538099

Two patients with superior vena cava syndrome (SVCS) secondary to lung carcinoma which recurred after maximum-dose radiation therapy were treated with placement of modified Gianturco expandable wire stents constructed in the authors' research laboratory. Symptoms of SVCS disappeared in 24 hours after stent placement, and the patients remained asymptomatic to their last follow-up, 2 1/2 months after the procedure (to the submission of this abstract). Both stents were widely patent at that time on superior vena cavograms and draining well the head, neck, and upper extremity circulation to the right atrium

Hand-assisted laparoscopic radical nephrectomy in the treatment of a renal cell carcinoma with a level ii vena cava thrombus  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Excision of renal cell carcinoma (RCC) with corresponding vena cava thrombus is a technical challenge requiring open resection and vascular clamping. A 58 year old male with a right kidney tumor presented with a thrombus extending 1 cm into the vena cava. Using a hand-assisted transperitoneal approach through a 7 cm gel-port, the right kidney was dissected and the multiple vascular collaterals supplying the tumor were identified and isolated. The inferior vena cava was mobilized 4 cm cephalad...

Dialysis Catheter-Related Superior Vena Cava Syndrome with Patent Vena Cava: Long Term Efficacy of Unilateral Viatorr Stent-Graft Avoiding Catheter Manipulation  

Science.gov (United States)

Central venous catheters are the most frequent causes of benign central vein stenosis. We report the case of a 79-year-old woman on hemodialysis through a twin catheter in the right internal jugular vein, presenting with superior vena cava (SVC) syndrome with patent SVC. The clinically driven endovascular therapy was conducted to treat the venous syndrome with a unilateral left brachiocephalic stent-graft without manipulation of the well-functioning catheter. The follow-up was uneventful until death 94 months later.

Case Presentation of Preureteral Vena Cava and Review of the Literature  

Directory of Open Access Journals (Sweden)

Full Text Available Retrocaval ureter, terms are anatomically descriptive but misleading in regard to development and results from altered vascular development. This anomaly is relatively uncommon, although it has clinical relevance. The ureter typically deviates medially behind the inferior vena cava, winding about and crossing in front of it from a medial to a lateral direction, to resume a normal course, distally, to the bladder. The renal pelvis and upper ureter typically appear elongated and dilated in a “J” or fishhook shape before passing behind the vena cava. Diagnoses were confirmed with intravenous urography and patient had an open surgical repair of the anomaly. The anomaly predominantly involves the right ureter, as was observed in these reported cases. Treatment is surgical allowing for correction of the anomaly with resolution of symptoms

Case report of pelvic arteriovenous malformation treated with transcatheter embolization. Application of vena cava filter  

Energy Technology Data Exchange (ETDEWEB)

A successful case (34-year-old, male) of trans-arterial embolization using Guenther's vena cava filter for controlling massive hemorrhage from a huge arteriovenous malformation in the pelvic region was reported. Some of the conventional embolic materials such as steel coil and cyanoacrylate were used in the initial attempt, it was, however, impossible to control bleeding because of the higher flow in the nidus. In the subsequent trial, Guenther's filter was placed into the right internal iliac artery which was the huge main feeder of the AVM, then it played an important role in the embolization of the feeder to avoid peripheral migration of the other embolic materials. Transarterial embolization in combination with a vena cava filter could be an effective therapy for huge arteriovenous malformations.

A caval homograft for Budd-Chiari syndrome due to inferior vena cava obstruction.  

Science.gov (United States)

Transjugular intrahepatic portosystemic shunt (TIPS) is the standard treatment of Budd-Chiari syndrome (BCS) non responsive to medical therapy. However, patients with inferior vena cava (IVC) obstruction proximal to the atrium do not benefit from TIPS and a surgical approach is mandatory. We report the case of BCS due to intrapericardial IVC obstruction. We describe a novel surgical approach using a fresh caval homograft. An attempt to balloon dilatation of the IVC obstruction was complicated by right atrial disruption with tamponade and ventricular fibrillation. Lately, the patient successfully underwent a reconstruction of the cavo-atrial continuity by the interposition of a fresh caval homograft, a novel surgical approach never described before for BCS. Further follow-up revealed progressive reduction and resolution of ascites, and overall clinical improvement. IVC obstruction near to the atrium can be surgically approached with a new technique consisting in inferior vena cava resection and replacement with a caval homograft. PMID:23717741

Entrapment of Guide Wire in an Inferior Vena Cava Filter: A Technique for Removal  

International Nuclear Information System (INIS)

Entrapment of a central venous catheter (CVC) guide wire in an inferior vena cava (IVC) filter is a rare, but reported complication during CVC placement. With the increasing use of vena cava filters (VCFs), this number will most likely continue to grow. The consequences of this complication can be serious, as continued traction upon the guide wire may result in filter dislodgement and migration, filter fracture, or injury to the IVC. We describe a case in which a J-tipped guide wire introduced through a left subclavian access without fluoroscopic guidance during CVC placement was entrapped at the apex of an IVC filter. We describe a technique that we used successfully in removing the entrapped wire through the left subclavian access site. We also present simple useful recommendations to prevent this complication.

Temporary Vena Cava Filters and Ultrahigh Streptokinase Thrombolysis Therapy: A Clinical Study  

International Nuclear Information System (INIS)

Purpose: To assess the efficacy of temporary vena cava filters in patients undergoing ultrahigh-dose streptokinase thrombolysis for iliocaval thrombosis and to determine therapy success and filter and therapy complications.Methods: Forty-five patients were studied regarding extension and characteristics of thrombosis, duration, success, and complications of thrombolysis therapy, filter type, access route, pulmonary embolisms, and filter complications.Results: Complete recanalization was achieved in 57% of cases. Filters were inserted predominantly via a transbrachial route. One fatal pulmonary embolism (2%) occurred 1 day after starting thrombolysis. No other pulmonary embolism was noted. Other complications were induced by thrombolysis alone (n = 12), thrombolysis and filter (n = 9), and filter alone (n = 11).Conclusion: Fatal pulmonary embolisms as a complication of ultrahigh-dose treatment of pelvic or caval thrombosis can not safely be prevented by the temporary vena cava filters currently available. Filter design needs to be improved

Local colloid trapping in the liver in the inferior vena cava syndrome  

Energy Technology Data Exchange (ETDEWEB)

Local radioactive areas in the liver were observed as a result of superficial cavoportal shunting of radiocolloids in two patients with the inferior vena cava syndrome. In one patient a paraumbilical and/or a recanalized umbilical vein was apparently involved in the hepatopetal shunting. In the other patient a superficial anastomosis other than the paraumbilical vein shunted colloid to the liver. Relatively discrete areas of increased radioactivity, single or multiple, were seen in the left lobe. Virtually all reported instances of hepatopetal shunting of radioparticles in a superior or an inferior vena cava syndrome have demonstrated similar findings. Various hepatopetal collateral pathways in infrarenal caval obstruction are considered, and factors that could affect liver scan findings in the infrarenal obstruction are discussed.

MR angiography of pelvic veins and of the inferior vena cava using 0,5 Tesla  

International Nuclear Information System (INIS)

The pelvic veins and/or the inferior vena cava were examined in 15 patients with pelvic vein thrombosis or retroperitoneal tumours, using phlebography or cavography and MR angiography. The latter was carried out using 0.5 Tesla with an inflow technique (T_R/T_E 30/8 ms, flip angle 70 ). 3-D projection angiograms were obtained from the 2-D angiograms in the coronary plane. Image quality was generally satisfactory and the veins up to the internal iliacs could be demonstrated in all cases; below this, the examination was unreliable. Comparison of the methods with reference to information of therapeutic relevance has shown that in two-thirds of all examinations (8/13) MR angiography and phlebography were of equal diagnostic value. In the presence of a renal cell carcinoma, MR angiography was unable to distinguish between thrombosis and infiltration of the vena cava. (orig.)

Transjugular intrahepatic portosystemic shunt with accidental diagnosis of persistence of the left superior vena cava  

Directory of Open Access Journals (Sweden)

Full Text Available Transjugular intrahepatic portosystemic shunt (TIPSS is considered a valid therapeutic option for the treatment of portal hypertension and its complications. The guidelines for this procedure have already been established on the basis of the normal vascular anatomy and of various technical radiological aspects. In some few rare cases, diagnosis of a congenital vascular anomaly can be made accidentally by interventional radiologists, making the procedure of the TIPSS placement extremely difficult or in some cases technically impossible. This report describes a rare vascular malformation characterized by the absence of the right superior vena cava and persistence of the left superior vena cava in a patient with a diagnosis of advanced liver cirrhosis who needed a TIPSS placement in order to control refractory ascites.

Incidentally Detected Pediatric Case with Absent Right Superior Vena Cava During Transcatheter VSD Closure  

Directory of Open Access Journals (Sweden)

Full Text Available Persistent left superior vena cava (PLSVC with an absent right superior vena cava (RSVC is an extremely rare congenital anomalie in normal atrial situs. Isolated cases are diagnosed incidentally during catheterization. In patients with PLSVC, due to frequent drainage of upper extremity, head and neck veins into coronary sinus, patients with enlarged coronary sinus should be suspected to have absence of the RVCS. In this report, we presented a 7-year-old girl who was diagnosed perimembranous VSD (ventricular septal defect, apparently enlarged coronary sinus, PLSVC with transthoracic echocardiography, and incidentally was recognized absence of RSVC during percutaneouse VSD closure. Consequently, we wanted to draw attention to echocardiographic and angiocardiographic findings of this rare venous anomaly.

Fat collections related to the intrahepatic inferior vena cava: CT features  

International Nuclear Information System (INIS)

Purpose: To evaluate fat collections related to inferior vena cava, their causes, and to make a review of the literature about these benign incidental findings. Materials and Methods: Two thousands and one hundred thoracoabdominal CT scans were performed between May 2000 and March 2001. We used a PQ 5000 spiral CT scanner. The studies were performed with and without contrast media. Results: We found three cases of fat collections related to inferior vena cava (IVC). They were located posteromedial and anteromedial to IVC. Conclusion: Fat collections related to the IVC are benign incidental findings. The knowledge with regards to these findings should preclude erroneous diagnosis of intracaval thrombus, intracaval lipomas or secondary extensions of tumors. (author)

O implante de filtro de veia cava, quando indicado em casos com duplicidade da veia cava inferior, pode ser realizado de diferentes formas: em ambas as veias cavas; em uma delas, embolizando a anastomose entre ambas; em somente uma delas; ou por implante supra-renal. Relatamos um caso de trombose venosa profunda no pós-operatório de implante de prótese de quadril com contra-indicação para tratamento anticoagulante e cuja cavografia evidenciou duplicidade de veia cava inferior. O implante de filtro de veia cava inferior realizado em posição supra-renal mostrou-se opção adequada e segura.Double inferior vena cava is a rare anatomic variation with prevalence ranging between 0.2-3.0%. In cases of duplication, inferior vena cava filter placement options include placing it in both vena cava, coil-embolization of the intervenous segment plus placing a filter in the right inferior vena cava, or suprarenal filter placement. We report a case of deep venous thrombosis after unilateral primary total hip replacement, presenting with contraindications for anticoagulant therapy, in which cavography showed inferior vena cava duplication. Inferior vena cava filter placement was performed in the supra-renal portion and was proved to be an adequate and safe procedure.

Full Text Available OBJETIVO: O tratamento cirúrgico da conexão anômala das veias pulmonares em veia cava superior, associada ao defeito septal atrial tipo seio venoso, é bem estabelecido e transcorre com baixa mortalidade e morbidade. Com a finalidade de diminuir a incidência de estenose ou oclusão da veia cava superior direita, especialmente quando associada à presença de veia cava superior esquerda, o apêndice atrial direito foi utilizado para ampliar a veia cava superior direita, após o desvio das veias pulmonares para o átrio esquerdo. MÉTODOS: No período entre junho de 1986 e setembro de 2008, foram operados 95 pacientes, consecutivos, portadores desta anomalia com drenagem em veia cava superior direita e porção alta do átrio direito. A idade variou de 6 meses a 68 anos e o sexo feminino predominou com 50 casos. RESULTADOS: No material apresentado, não ocorreu nenhum óbito na fase de pós-operatório imediato ou tardio. O ritmo cardíaco permaneceu sempre sinusal e não ocorreram complicações na evolução. CONCLUSÃO: O presente trabalho demonstra a aplicabilidade da técnica descrita, com resultados favoráveis em relação a mortalidade, distúrbios de ritmo e complicações na região da veia cava superior direita.OBJECTIVE: Surgical treatment of anomalous pulmonary venous connection to the superior vena cava, associated with sinus venous atrial septal defect, is well established and correlates with low mortality and morbidity. In order to reduce the incidence of stenosis or occlusion of the right superior vena cava, especially when associated with the presence of left superior vena cava, the right atrial appendage was used to enlarge the right superior vena cava, after the diversion of the anomalous pulmonary veins for the left atrium. METHODS: Between June 1986 and September 2008, 95 consecutive patients were operated with anomalous drainage in the superior right vena cava and high right atrium. Ages ranged from 6 months to 68 years and females predominated with 50 cases. RESULTS: There was no death in the immediate or late post operative care. The sinus cardiac rhythm was preserved in all cases and there was no complications in the late follow up. CONCLUSION: This paper demonstrates the applicability of the technique described, with favorable results on mortality, rhythm disturbances and complications in the right superior vena cava.

Surgical management of retroperitoneal leiomyosarcoma arising from the inferior vena cava.  

Science.gov (United States)

Retroperitoneal leiomyosarcomas are uncommon tumors, with approximately 300 documented cases in the literature. Management necessitates complete surgical resection in order to offer patients a chance at long-term cure. Resection often presents a challenge as these tumors are often large, involving adjacent structures, and may require reconstruction of the inferior vena cava (IVC). In this article, we will present background information on retroperitoneal leiomyosarcomas and the technical aspects of surgical resection and vascular reconstructive options of the IVC.

Follow-up studies of vena cava filters: Real-time sonography and abdominal films  

International Nuclear Information System (INIS)

In 16 patients with vena cava filters (12 Guenther filters, 4 Kimray-Greenfield filters) a follow-up study was performed by ultrasound and abdominal plain film. Ultrasound allows to identify type and location of the filter as well as the entrapment of emboli. Abdominal radiography is useful for exact evaluation of changes in filter position. Combination of sonography and plain films is considered to be most suitable for follow-up studies of caval filters. (orig.)

Bilateral adrenal cystic neuroblastoma with superior vena cava syndrome and massive intracystic haemorrhage  

Energy Technology Data Exchange (ETDEWEB)

Bilateral cystic adrenal tumours are a rare presentation of neuroblastoma. Intratumoural haemorrhage is a frequent finding in neuroblastoma, but is rarely symptomatic. We present an 11-month-old girl with predominantly cystic bilateral neuroblastomas and distant lymph-node metastasis. Massive intracystic haemorrhage and superior vena cava (SVC) syndrome were ominous prognostic factors, leading to death. Large tumours with intracystic haemorrhage might require a conservative approach. (orig.)

Lymphangiomatosis Involving the Inferior Vena Cava, Heart, Pulmonary Artery and Pelvic Cavity  

Energy Technology Data Exchange (ETDEWEB)

A 38-year-old woman who had undergone pelvic lymphangioma resection two months previously presented with cough and dyspnea. Transthoracic echocardiography and CT demonstrated the presence of a mixed cystic/solid component tumor involving the inferior vena cava, heart and pulmonary artery. Complete resection of the cardiac tumor was performed and lymphangioma was confirmed based on histopathologic examination. To the best of our knowledge, this is the first report of lymphangiomatosis with cardiac and pelvic involvement in the published clinical literature.

An alternative approach for endocardial pacemaker lead implantation in patient with persistent left superior vena cava  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Introduction. Persistent left superior vena cava represents a congenital vascular defect of the venous system, which often makes standard 58 cm endocardial lead placement impossible. Case Outline. A right chamber approach by the left cephalic vein was tried. This was impossible because standard endocardial lead (SJM Isoflex S 1646T, bipolar lead, 58 cm in length, body diameter 7 French) was too short for this patient. A unipolar lead for coronary sinus (Medtronic ATTEIN 4193-88), 88 cm in len...

Technical Error During Deployment Leads to Vena Cava Filter Migration and Massive Pulmonary Embolism  

International Nuclear Information System (INIS)

The Guenther Tulip vena cava filter is a safe, effective, well-established device for pulmonary embolism prophylaxis. We report a patient in whom there was migration of the filter to the right atrium, 2 weeks after insertion, caused by a technical error during deployment. An attempt to retrieve the filter percutaneously failed, necessitating removal at open-heart surgery. The potential causes of migration are described and the lessons learned from this unusual case are outlined.

Gallium SPECT detection of neoplastic intravascular obstruction of the superior vena cava  

Energy Technology Data Exchange (ETDEWEB)

A rare case of an intravascular neoplastic obstruction of the superior vena cava is discussed. The lesion was detected with gallium single photon emission computed tomography (SPECT) despite a normal appearance on a concurrent radiographic CT study. A computer-generated composite SPECT-CT image confirmed the intravascular localization of the radioisotope, and a subsequent CT-guided transthoracic needle biopsy revealed a poorly differentiated adenocarcinoma.

Leiomyosarcoma of the retrohepatic vena cava treated by excision and reconstruction with an aortic homograft: a case report and review of literature.  

Science.gov (United States)

Leiomyosarcoma of the retrohepatic inferior vena cava is a rare entity and presents a number of diagnostic and therapeutic challenges. Here such a case is presented in which the retrohepatic inferior vena cava was excised after full mobilization of the liver under venovenous bypass. The continuity of the vena cava was restored with cryopreserved aortic homograft. The technical details with regard to total vena caval clamping, venovenous bypass, hepatic inflow occlusion, techniques of reconstruction, including the use of cryopreserved aortic homograft, and a brief review of the literature on the surgical management of retrohepatic inferior vena caval tumors are discussed.

Leiomyosarcoma of the inferior vena cava level II involvement: curative resection and reconstruction of renal veins.  

Science.gov (United States)

Leiomyosarcoma of the inferior vena cava (IVCL) is a rare retroperitoneal tumor. We report two cases of level II (middle level, renal veins to hepatic veins) IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts. In our cases, IVCL is documented to be occluded preoperatively, therefore, radical resection of tumor and/or right kidney was performed and the distal end of inferior vena cava was resected and without caval reconstruction. None of the patients developed edema or acute renal failure postoperatively. After surgical resection, adjuvant radiation therapy was administrated. The patients have been free of recurrence 2 years and 3 months, 9 months after surgery, respectively, indicating the complete surgical resection and radiotherapy contribute to the better survival. The reconstruction of inferior vena cava was not considered mandatory in level II IVCL, if the retroperitoneal venous collateral pathways have been established. In addition to the curative resection of IVCL, the renal vascular reconstruction minimized the risks of procedure-related acute renal failure, and was more physiologically preferable. This concept was reflected in the treatment of the two patients reported on. PMID:22742531

Systemic-to-pulmonary venous shunt in superior vena cava obstruction: depiction on computed tomography venography  

International Nuclear Information System (INIS)

PURPOSE: To describe computed tomography (CT) venographic appearances of systemic-to-pulmonary venous shunts with CT venography and three-dimensional reconstruction images from patients with superior vena cava obstruction. MATERIAL AND METHODS: From January 1994 to April 2002, CT venography was performed in 45 patients with superior vena cava obstruction using a single-detector helical CT scanner (n=38) and four-detector row CT scanner (n=7). Analysis of CT scan data included the cause and degree of venous obstruction, the presence of pleural thickening and enhancement, and the attenuation of pulmonary veins. The causative factor for systemic-to-pulmonary venous shunt was evaluated using the Fisher exact test. RESULTS: Systemic-to-pulmonary venous shunts were observed in four patients (9%) who had high-attenuated pulmonary veins and pleural enhancement on CT venography. Pleural thickening (P=0.01) and a history of pulmonary tuberculosis (P=0.034) are statistically significant risk factors. CONCLUSION: CT venography showed strong pleural enhancement and high-attenuated pulmonary veins indicating systemic-to-pulmonary venous shunts. Radiologists should study the earlier enhancement of pulmonary veins in patients with superior vena cava obstruction

Interventional therapy of lower extremity deep vein thrombosis under protection of temporary vena cava filter  

International Nuclear Information System (INIS)

Objective: To determine the usefulness and complication of interventional therapy of deep venous thrombosis (DVT) with local thrombolysis or a combination of mechanical thrombectomy and local thrombolysis under the protection of temporary vena cava filter, and to assess the efficacy of temporary vena cava filter. Methods: Thirty-two patients with DVT were treated with catheter-directed local thrombolysis (n=20) or a combination of hydrodynamic thrombectomy and local thrombolysis (n=12) after insertion of a temporary caval filter. 34 temporary caval filters were inserted and two cases received 2 filters. Results: Successful recanalization was achieved in 75% of patients. A complete lysis was achieved in 17 cases (53%), and thrombolysis of 50%-100% in 7 cases (22%). The mean durations for local thrombolysis alone were 61.7 hours and for the combination of thrombolysis with hydrodynamic thrombectomy were 30.3 hours. There was a statistically significant difference between the two methods (t=3.08, P<0.01). No clinical relevant pulmonary embolism occurred during the therapy procedure. Conclusion: A combination of mechanical thrombectomy and local thrombolysis with the use of temporary vena cava filter provides a more safe method in the therapy of DVT. The insertion of a temporary caval filter is promising in the reduction of pulmonary embolism

Vena Cava Filter Behavior and Endovascular Response: An Experimental In Vivo Study  

International Nuclear Information System (INIS)

Purpose: To evaluate the behavior and endovascular response of a new nitinol permanent vena cava filter, the TrapEase. Methods: Percutaneous implantation of the filter was performed in six goats, with inferior vena cava (IVC)diameter close to that of man. Radiologic data concerning the IVC,filter diameter, patency and stability were collected. At 2, 4, 20 and 26 weeks post-implantation, histopathologic analysis of the IVC wall was performed at the site of filter distension, and distal and proximal to the filter. Results: All filters remained patent.There was no migration and no signs of biological incompatibility.Signs of neointimalization were seen at 2 weeks, with well-developed neointima at 4 weeks. No acute vessel wall perforation was detected by cavography at implantation. During follow-up histologic analysis at 26 weeks, perforation of some of the small fixation barbs was seen,causing minimal damage to the vessel wall and adjacent organ tissue without impairing organ function. These events were well tolerated, probably due to the gradual nature of the penetration of fixation barbsallowing reactive fibrous tissue development. At 26 weeks the parallel filter struts were well covered with neointima and did not perforate the vessel wall. There were no complications associated with the filter implantation. Conclusions: The TrapEase vena cava filter was well tolerated and is suitable for incorporation into the IVC wall of healthy animals without any apparent deleterious reaction due to biological incompatibility

International Nuclear Information System (INIS)

Objective: To evaluate the imaging findings of congenital anomalies of inferior vena cava (IVC) with 64-slice spiral CT. Methods: Between January 2008 and May 2009, 6986 patients who had routine abdominal 64-row multi-detector computed tomography were retrospectively analyzed for congenital anomalies of IVC. Results: Among 6896 cases, 25 cases with congenital anomalies of IVC were identified. Six case were left IVC, showing IVC left to the aorta inferior to the renal hilum, Ten cases were double IVC, showing two IVC besides the aorta inferior to the renal hilum. Five cases were abnormal renal vein, showing retroaortic and circumaortic left renal vein. Two cases were IVC interruption with collateral circultion by azygous or hemiazygous vein, contrast-enhanced CT scan showing deficiency of t he IVC between hepatic and renal hilums, the enlarged azygos vein communicating with IVC at renal level and the hepatice vein draining into the right atrium. Venography showed that IVC draining into the superior vena cava through azygous or hemiazygous veins. One case was interruption of the IVC with portal vein continuation, contrast-enhanced CT scan showing the communication between the IVC and portal vein. One case was hemiazygos continuation of a left IVC, contrast-enhanced CT scan demonstrating dilatation hemiazygos continuation of a left IVC and jointed the azygos vein. Conclusiong: The 64-slice spiral CT can be a diagnostic standard for congenital anomalies of inferior vena cava. (authors)

Scintiangiographic Visualization of Systemic-Portal Venous Shunting as a Cause of 'hot Spot' in Superior Vena Cava Obstruction  

International Nuclear Information System (INIS)

A small number of pathologic entities such as Budd-Chiari Syndrome, cirrhosis, focal nodular hyperplasia, and superior and inferior vena cava obstruction has been reported to result in focal areas of increased uptake of radiocolloid on the hepatoscintigram. We recently studied a patient with focal accumulation of 99mTc-phytate at the inferior aspect of the liver, at the junction of the right and left lobe. The superior vena cava scintiangiogram was taken for the evaluation of the superior vena cava obstruction and collateral circulations. As a result of superior vena caval obstruction a considerable amount of blood flowed to the liver through the anterior parietal and periumblical venous channels. A certain fraction of radiocolloid delivered by the rete mirabile perfused to a localized area of the liver. This would explain the hot spot around the porta hepatis in this case.

Prótese intracava provisória no tratamento de lesão da veia cava retro-hepática Temporary intracaval prothesis in treatment of retrohepatic vena cava injury  

Directory of Open Access Journals (Sweden)

Full Text Available One of the most difficult challenges to surgeons is the treatment of wounds on the retro hepatic vena cava. The anatomic particularities of this venous segment make its approach and treatment difficult, contributing to a high morbidity and mortality. Several techniques have been described for the treatment of these types of lesions. In this particular case, authors have chosen the introduction of a fastened provisory intra caval prothesis, without primary suturing of the wounds. The provisory intra caval prothesis can be an option for the treatment of retro hepatic vena cava lesions.

Relationship between Microscopic Hematuria and Inferior Vena Cava Reflux on Color Doppler Ultrasonography  

Directory of Open Access Journals (Sweden)

Full Text Available We examined the relationship between microscopic hematuria and inferior vena cava (IVC reflux. Transabdominal color Doppler ultrasonography of the IVC was performed in the supine position with the convex probe positioned perpendicular to the upper abdominal wall, and the extent of reflux into the IVC with each heart beat was examined near the diaphragm. A total of 171 patients were studied who had no diseases that could cause hematuria, and no symptomatic gross hematuria. The relationship between the existence and severity of IVC reflux and urine occult blood was examined. The 98 males included 50 subjects without IVC reflux and 48 with reflux, while the 73 females included 24 without IVC reflux and 49 with IVC reflux, respectively. The occurrence of IVC reflux was unrelated to age, but the prevalence of reflux was significantly higher in females than males. As the grade of IVC reflux increased, there was an increase in the prevalence and the severity of hematuria in both males and females. In conclusion, IVC reflux could be related to the occurrence of microscopic hematuria. Renal or urinary tract congestion secondary to IVC reflux may be one of the factors contributing to hematuria.

Optimizing the use of inferior vena cava filters in oncology patients: are all filters created equally?  

Science.gov (United States)

Many studies have supported the efficacy of inferior vena cava filters (IVCF) in the setting of venous thromboembolic disease, particularly in oncologic patients who are at increased risk. The advent of retrievable IVCF designs has prompted dramatically expanded use for patients with widely accepted indications but also disproportionately so in patients with so-called extended indications. At the same time, an alarming increase in filter-related complications has been reported both in the literature and through regulatory agencies, leading to government agency-issued warnings. The synergistic effect of these two interconnected phenomena is explained through a careful review of the evolution of IVCF device design. Critical differences exist when comparing retrievable IVCF and permanent IVCF. IVCF utilization can be optimized by prospectively identifying which patients are best served by a specific IVCF device. Careful follow-up strategies are also needed to ensure that all IVCFs are removed as soon as they are no longer needed. Finally, adjunctive techniques for removing "difficult" filters help maximize the number of IVCF removed and minimize IVCF left implanted needlessly. PMID:24610401

Role of cardiac output and the autonomic nervous system in the antinatriuretic response to acute constriction of the thoracic superior vena cava.  

Science.gov (United States)

Study of the differential characteristics of hepatic congestion and decreased cardiac output in terms of potential afferent stimuli in the antinatriuretic effect of acute thoracic inferior vena cava (TIVC) constriction. An attempt is made to see if the autonomic nervous system is involved in the antinatriuretic effect of acute TIVC or thoracic superior vena cava constriction.
