Use of a retrievable suprarenal inferior vena cava filter as a primary intervention for postpartum ovarian vein thrombosis: a case report

BACKGROUND: Postpartum ovarian vein thrombosis is a rare diagnosis with a significant associated risk of pulmonary embolism. The mainstay of therapy consists of intravenous antibiotics and anticoagulation. CASE: A 30-year-old woman presented with fever and abdominal pain 3 days after cesarean section and was found to have an ovarian vein thrombosis on computed tomography. Given her history of cerebral arteriovenous malformation and the attendant risk for cerebral hemorrhage with the use of anticoagulation, she was successfully treated with a removable suprarenal inferior vena cava (IVC) filter and intravenous antibiotics. CONCLUSION: For patients who fail to respond to anticoagulation alone or in whom anticoagulation is contraindicated, placement of a retrievable suprarenal IVC filter is a viable treatment option in the setting of postpartum ovarian vein thrombosis.     

Intrapartum placement of an inferior vena cava filter for a woman with hereditary antithrombin III deficiency: its role in the prevention of fatal pulmonary embolism

We present a case of a pregnant woman with hereditary antithrombin III deficiency and deep vein thrombosis of the left lower extremity managed by perinatal unfractionated heparin injection with antithrombin III replacement as well as by intrapartum placement of a temporary inferior vena cava filter. A massive thrombus of the right common iliac vein occurred during the intrapartum period despite antithrombin III replacement. An inserted filter could prevent fatal pulmonary embolism in this patient. Hereditary antithrombin III deficiency increases risk of thrombosis during pregnancy. However, discussion on intrapartum management, when anticoagulants are contraindicated due to possible hemorrhage, is minimal. Our experience suggests that thrombosis can occur and develop during the intrapartum period in an antithrombin III deficient woman despite antithrombin III replacement. It may be advisable to manage deliveries with temporary inferior vena cava filters to prevent fatal pulmonary embolism.     

May-Thurner syndrome resulting in acute iliofemoral deep vein thrombosis during the second trimester of pregnancy

Described is a 27-year-old pregnant woman with May-Thurner syndrome who experienced extensive pelvic and lower extremity thromboses during the antepartum period. The patient was referred for a symptomatic deep venous thrombosis at 23 weeks of gestation. Ultrasonography demonstrated a massive thrombus in the left iliofemoral vein. Heparin was given intravenously. Due to the possibility of pulmonary embolism during or immediately after delivery, a temporary inferior vena cava filter was inserted at 36 weeks of gestation. Labor was induced at 37 + 5 weeks of gestation; labor proceeded uneventfully and a male infant was born. Postpartum computed tomography (CT) demonstrated compression of the left common iliac vein by the right common iliac artery and lumbar vertebra. CT venogram demonstrated poor flow through the common iliac vein and well-developed collateral vessels. Critical stenosis at the origin of the left common iliac vein was consistent with a diagnosis of May-Thurner syndrome.     

Use of a retrievable inferior vena cava filter in term pregnancy: Case report and review of literature

Venous thromboembolism is a significant cause of morbidity and mortality in obstetrics. Management with anticoagulation can be problematic, especially peripartum. We report the successful placement and retrieval of an inferior vena cava filter as prophylaxis for peripartum pulmonary embolism in a woman with a large, proximal, deep venous thrombosis at term.     

Use of a temporary vena cava filter in a woman with septic abortion and inferior vena cava thrombosis. A case report

BACKGROUND: Ovarian vein and inferior vena cava (IVC) thrombosis are rare but life-threatening complications of severe obstetric infections. IVC filters have been used to reduce the risk of pulmonary embolus in patients who have recurrent thrombotic and embolic events or underlying risk factors. More recently, retrievable IVC filters have been used in patients in whom the risk is transient. CASE: At 18 weeks' gestation a multigravida with a fetus with anencephaly became septic after Laminaria placement and rupture of the membranes. She developed ovarian vein and IVC thrombosis and was treated successfully with a retrievable IVC filter, anticoagulation and antibiotics. The filter was removed after 9 days. CONCLUSION: In young patients at transient risk for emboli and requiring placement of an IVC filter, a retrievable filter should be considered to reduce the long-term risks of an indwelling filter.     

Trombosis de vena ovárica y vena cava inferior asociada a endometritis en el puerperio

Ovarian vein thrombosis is a rare and severe puerperal complication that usually manifests as fever and abdominal pain in the puerperal period and is more frequent in women who have undergone cesarean section. There is an associated high risk of pulmonary embolism and thus early diagnosis and treatment are required. We report the case of a 30-year-old woman with pelvic pain and fever in the puerperal period. Computed tomography scan revealed ovarian vein thrombosis extending to the inferior vena cava. Endometritis was also diagnosed. The patient received dalteparin and antibiotics. Ovarian vein thrombosis should be included in the differential diagnosis of fever in the postpartum period.     

Thrombophlebitis of the right ovarian vein with thrombosis of the inferior vena cava in the post-partum

A 31-year-old woman presented, in post-partum day two, an abdominal pain associated with fever. Appendicitis was suspected on clinical and radiological elements, and a laparoscopy carried out. This found a normal appendix but a right ovarian vein thrombophlebitis. A second injected scan confirmed the diagnosis, the right renal vein and the inferior vena cava being affected. We started an anticoagulation treatment associated with a large antibiotherapy. The patient was transferred to the intensive care unit to prevent the risk of pulmonary embolism.     

Management of a massive pulmonary embolism in a pregnant patient with mechanical fragmentation followed by delayed catheter-directed thrombolysis in the early postpartum period

There are limited data available on the management of massive pulmonary embolism in pregnancy. The use of systemic thrombolysis has been reported, but there are few documented cases on the use of mechanical fragmentation or catheter-directed thrombolysis. Systemic thrombolysis in pregnancy increases the risk of major hemorrhage and there are reports of massive subchorionic hematomas following its use. We describe the use of mechanical fragmentation and optional retrievable inferior vena cava (IVC) filter insertion in a 38-week pregnant woman followed by delayed pharmacological catheter-directed thrombolysis during the early postpartum period to successfully treat a massive pulmonary embolism.     

Deep venous thrombosis associated with large leiomyomata uteri. A case report

BACKGROUND: The association of deep venous thrombosis (DVT) with uterine leiomyomata has been reported only rarely in the English-language literature. These concomitant findings occurred in a woman with no other known risk factors for development of DVT. CASE: A 49-year-old, Caucasian woman, gravida 3, para 3, with a past medical history significant for large uterine leiomyomata, menorrhagia and anemia, presented with acute edema of the left lower extremity. Doppler studies revealed compression of the left iliofemoral vein with associated thrombosis. No risk factors for DVT were identified. Intravenous heparin was initiated, with eventual preoperative placement of an inferior vena cava Greenfield filter. A total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed without complications. CONCLUSION: Large uterine leiomyomata are a potential cause of lower extremity venous stasis and resulting thrombosis and can be treated with hysterectomy.     

Filtro de vena cava inferior ante diagnóstico de trombosis venosa profunda en gestante en trabajo de parto. A propósito de un caso clínico

IntroductionPregnancy represents a procoagulant state that increases women's risk of thrombotic phenomena. As in the non-pregnant population, we must diagnose and treat these events as early as possible to avoid the migration of the thrombus to other locations. Anticoagulation is the first-line therapeutic measure. However, certain situations of increased bleeding such as labor may be a contraindication to initiate such anticoagulation. The following article develops a clinical case in which the deep vein thrombosis diagnosis occurred at the onset of labor.Main symptoms and/or clinical findingsIncrease in diameter of the left lower limb, with redness of the same and increase in local temperature. The patient described pain at the level of this limb for 15 days. He had no dyspnea and oxygen saturation was 100%.Main diagnosesDeep vein thrombosis, labor.Therapeutic interventionsThe contraindication of anticoagulation and the need for immediate treatment raised the inferior vena cava filter as the most reasonable option.ResultsAfter the placement of the filter, the delivery proceeded without incident. The plunger did not migrate and the filter was removed 29 days after delivery without complications.ConclusionDespite our limited clinical experience in the management of these cases, we can affirm that the inferior vena cava filter represents a reasonable and safe option in cases of thrombosis of the lower limbs in women in labor.     

Postpartum Budd-Chiari syndrome with prolonged hypercoagulability state

Budd-Chiari syndrome after pregnancy is an extremely rare disease. Reported here is a case of postpartum Budd-Chiari syndrome with unusual features of prolonged hypercoagulability state. The disease occurred 2 weeks after delivery and despite massive anticoagulation treatment the patient developed severe hepatic vein occlusion, renal vein thrombosis, inferior vena cava thrombosis, and femoral artery thrombosis.     

Puerperal pelvic thrombophlebitis: impact on diagnosis and treatment using x-ray computed tomography and magnetic resonance imaging

The clinical diagnosis of puerperal pelvic thrombophlebitis was confirmed by x-ray computed tomography in 11 women, and further documented in six by magnetic resonance imaging. Venous thrombi were demonstrated in ovarian, iliofemoral, and inferior vena caval vessels. In six women with ovarian vein involvement and no evidence of iliofemoral thrombophlebitis, resolution followed intravenous antimicrobial therapy alone, and in three of these, resolution was confirmed by x-ray tomography. In contrast, three of five women with symptomatic iliofemoral thrombophlebitis had a prolonged febrile course despite antimicrobial and heparin therapy. The clinical courses of these 11 women were consistent with the observation that pelvic thrombophlebitis is associated with pelvic infection. Disease manifested within a few days after parturition was more likely due to ovarian vein involvement, whereas disease with later onset of symptoms was more likely due to iliofemoral thrombosis, with or without vena caval extension. Through the use of x-ray computed tomography and magnetic resonance imaging, the natural course of pelvic thrombophlebitis can be better elucidated and therapeutic regimens more clearly evaluated.     

Vena cava filter in patients with gynecologic cancer complicated by pulmonary embolism and progressive hypercoagulability

The aim of the study was to verify the validity of placement of a vena cava filter in patients with gynecologic cancer complicated by pulmonary embolism and progressive persistent hypercoagulability. The authors discuss two patients with pulmonary embolism. In this study, a gynecologic tumor was diagnosed, one presented endometrial carcinoma and the other ovarian papillary carcinoma, after the position of vena cava filter and treatment with urokinasi (2.800.000 UI/ml) it was possible to do surgery followed by radiation therapy in the first case and chemotherapy in the second. In these cases there are indications for the placement of a vena cava filter. This has enabled surgery and anticoagulation therapy and has prevented the movement of any other emboli, which were later dissolved by fibrinolytic agents, and the effectiveness result was the arrest of progressive hypercoagulability moved by tumor cell. The serious conditions that were related to prior embolism and to a persistent thrombotic state characterized by progressive hypercoagulability did not make it possible to perform surgery or any other type of therapy because of absolute contraindications. The decision to place the filter could thus become the first step towards subsequent improvements, that are also tied to the possibility of performing surgery for removing tumor, arrest of progressive hypercoagulability due to tumor cell, allow chemotherapy or radiation treatment.     

Use of the inferior vena cava clip in patients at high risk for pulmonary embolism

Sixteen gynecologic oncology patients at high risk of developing a postoperative pulmonary embolism underwent prophylactic clipping of the inferior vena cava during laparotomy for tumor resection. All patients had a prior history of deep venous thrombosis or pulmonary embolism or had an active deep venous thrombosis at the time of their surgery. Additionally, this group of 16 patients was characterized as being at high risk for recurrent thrombosis in the postoperative period based on traditional risk factors that are representative of most gynecologic oncology patients. The Adams-DeWeese or Moretz clip was used in this series. There were no pulmonary emboli in our 16 patients in the postoperative period or during follow-up. There were no signs of venous stasis attributable to clip placement. The procedure was quick, simple, and complication free and the external clip has the advantage of maintaining effectiveness throughout the patient's lifetime. Prophylactic clipping of the inferior vena cava at the time of laparotomy in patients at an increased risk of thrombosis deserves further study.     

Use of inferior vena cava filters in thromboembolic disease during labor: Case report with a literature review

Thromboembolic diseases during pregnancy are usually managed by conventional anticoagulation and patients are at high risk of pulmonary embolism. Inferior Vena Cava (IVC) filters can be used in cases of documented pulmonary embolism (PE) where anticoagulation is contraindicated or has failed. In our case the patient was diagnosed as having a deep vein thrombosis (DVT) and was started on anticoagulant therapy. Twenty four hours afterwards she went into labor and an IVC filter was inserted due to the risk of pulmonary embolism. She was managed successfully during labor and postpartum period. This shows that IVC filters can be used during labor to try and prevent pulmonary emboli.

Risk factors for deep vein thrombosis and pulmonary embolism during pregnancy or post partum: a population-based, case-control study

OBJECTIVE: We sought to determine risk factors for deep vein thrombosis and pulmonary embolism during pregnancy or post partum. STUDY DESIGN: We performed a population-based case-control study. All Olmsted County, Minnesota, residents with a first lifetime deep vein thrombosis or pulmonary embolism during pregnancy or post partum from 1966 to 1990 were identified (N = 90). Where possible, a resident without deep vein thrombosis or pulmonary embolism was matched to each patient by date of the first live birth after the patient's child. The medical records of all remaining patients and all control subjects were reviewed for >25 baseline characteristics, which were tested as risk factors for deep vein thrombosis or pulmonary embolism. RESULTS: In multivariate analysis smoking (odds ratio, 2.4) and prior superficial vein thrombosis (odds ratio, 9.4) were independent risk factors for deep vein thrombosis or pulmonary thrombosis during pregnancy or post partum. CONCLUSION: Venous thromboembolism prophylaxis may be warranted for pregnant women with prior superficial vein thrombosis. Smoking cessation should be recommended, especially during pregnancy and the postpartum period.     

Antibiotikaresistentes Fieber im Wochenbett

Septic pelvic thrombophlebitis is a rare disease (<0.1% total births) but the incidence is much higher after cesarian section. Disposition factors are a dilatation of the ovarian veins with simultaneous rapidly sinking venous blood pressure postpartum and increased rate of coagulation. Early imaging is barely possible so that the clinical diagnosis remains the critical factor. The treatment of choice is broad spectrum antibiotics (effective against Streptococceae, Enterobacteriaceae and anerobic pathogens) combined with therapeutic anticoagulation. The risks of septic pelvic thrombophlebitis are spreading of the thrombus into the inferior vena cava and the renal veins, pulmonary embolism and generalised sepsis. Typical symptoms are high fever despite antbiotic therapy, astounding freedom from pain between fever attacks and greatly increased inflammation parameters. For the most important differential diagnosis, primary ovarian vein thrombosis, the main symptom is postpartal lower abdominal pain and fever does not occur in 40-60% of cases. Later complications are not to be expected and an increased tendency to thrombosis is not present during subsequent pregnancies.     

New criteria for placement of a prophylactic vena cava filter

In order to identify patients who, having had an initial pulmonary embolism, are likely to develop recurrent emboli despite adequate anticoagulation therapy, ten patients (group 1) with documented recurrent pulmonary embolism during anticoagulation therapy were compared with 31 patients (group 2) who showed no evidence of recurrent emboli during the treatment period. Risk factors for thromboembolic disease were similar between the two groups. Noninvasive venous studies of the lower extremities, including Doppler venous ultrasound and phleborheography (PRG), were performed upon all patients after the initial embolic event. Of the ten patients in group 1, seven (70 per cent) had clinical signs of deep vein thrombosis (DVT). Doppler studies were positive for eight of the nine patients studied, and PRG studies were positive for eight of eight patients tested. In contrast, of the 31 patients who responded well to medical therapy, one patient (3 per cent) had clinical signs of DVT, three patients (10 per cent) had positive Doppler studies and one patient (3 per cent) had a positive PRG. Combined Doppler and PRG studies were positive in 100 per cent of the patients in group 1 but in only 6 per cent of the patients in group 2 (p less than 0.001). The results of this study suggest that patients having an initial pulmonary embolism and DVT of sufficient extent detected by noninvasive studies may be at an increased risk for recurrent PE despite anticoagulation therapy. Insertion of a vena cava filter should be considered in these patients prior to the second embolic event.     

Computed tomographic features of puerperal ovarian vein thrombosis

Puerperal ovarian vein thrombosis is a dangerous complication of childbirth and often leads to inferior vena cava thrombosis and multiple pulmonary emboli. Computed tomography of the abdomen is useful in early diagnosis. Two patients with typical computed tomographic features are presented.
