Lysis of a left ventricular thrombus with recombinant tissue plasminogen activator

A 23-year-old woman with peripartum cardiomyopathy presented with a 2.1 x 2.5-cm pedunculated, mobile, left ventricular thrombus and evidence of systemic embolization. Due to the patient's poor left ventricular function, thrombectomy was not a viable option. Treatment with high-dose IV heparin was initially utilized but was unsuccessful as the thrombus appeared to enlarge on echocardiography. An accelerated weight-adjusted dose of recombinant tissue plasminogen activator (rt-PA) successfully lysed the thrombus without evidence of embolization. Although rt-PA has been used for primary lysis of high-risk ventricular thrombi, this is the first documentation of successful lysis of a left ventricular thrombus in a patient with peripartum cardiomyopathy.

Management of the critically ill cardiac patient

The decline in rheumatic fever has made heart disease in pregnancy an uncommon problem in the developed world but it remains an important cause of maternal morbidity and mortality in developing countries. Pregnancy is particularly dangerous in the presence of cyanotic congenital heart disease, Eisenmenger's syndrome, primary pulmonary hypertension, Marfan's syndrome, dilated cardiomyopathy and significant mitral stenosis. Severe stenosis is often complicated by pulmonary hypertension and atrial fibrillation. Maternal disease status should be determined using echocardiography to define cardiac anatomy, assess ventricular function and estimate intracardiac pressure gradients. Patients in the New York Heart Association functional classes 1 and 2 generally have a favourable outcome. Closed mitral commissurotomy is safe and effective in relieving stenosis across the mitral valve in selected patients. More recently the technique of percutaneous balloon mitral valvotomy has successfully been used in the treatment of mitral stenosis. Termination of pregnancy is advised in patients with severe pulmonary hypertension, including Eisenmenger's syndrome.

Current assessment of thromboembolic disease and pregnancy

This study was undertaken to assess incidence of deep venous thrombosis and pulmonary emboli in an inner-city pregnant population. Thromboembolic disease is believed to occur in 0.05 to 0.1 per cent of all pregnancies. Historically, postpartum thromboembolic disease was more common; decreased hospital stay may shift the thromboembolic disease to the antepartum period. A 5-year retrospective review of 4910 births assessed for incidence of thromboembolic disease, methods of diagnosis and treatment, and risk factors. A total of 4910 deliveries with 3978 transvaginal resulted in 30 episodes of deep venous thrombosis and five pulmonary emboli. All incidences of deep venous thrombosis but one were left-sided; four of five pulmonary emboli were postpartum. Of the epidsodes of deep venous thrombosis 17 per cent were first trimester, 50 per cent second trimester, 27 per cent third trimester, and 6 per cent postpartum. The diagnosis was confirmed by duplex scan in 24 of 30 patients. Heparin was the standard treatment. Deep venous thrombosis in pregnancy is most common in the second trimester; pulmonary emboli remain most common postpartum.

Acute respiratory distress syndrome in pregnancy and the puerperium: causes, courses, and outcomes

OBJECTIVE

To describe causes, courses, complications, and outcomes of patients with pregnancy-associated acute respiratory distress syndrome (RDS).

METHODS

Twenty-eight women with ARDS during pregnancy or within a week postpartum formed the study population. Eight cases had been reported previously. Charts were abstracted for maternal demographics, etiology, and treatment of acute RDS, and maternal outcomes. For antepartum acute RDS, newborn charts were also reviewed.

RESULTS

The incidence of acute RDS, excluding maternal transports, was one per 6277 deliveries or 0.016% (95% confidence interval [CI] 0, 0.027%). Leading causes were infection (12 cases), preeclampsia or eclampsia (seven cases), and aspiration (three cases). Eleven mothers died, a maternal mortality rate of 39.3% (CI 21.5%, 59.4%). Six of eight women who were ventilated for over 14 days survived. Nine of the acute RDS cases might have been preventable. Ten mothers with living fetuses were ventilated during the third trimester; nine delivered within 4 days. Among six infants delivered because of fetal heart rate abnormalities, one died and at least three had evidence of asphyxia.

CONCLUSIONS

Acute RDS occurs more frequently in pregnancy than the 1.5 cases per 100,000 per year reported for the general population. Prolonged ventilator support is warranted. The high rate of perinatal asphyxia in infants who have fetal heart rate abnormalities supports a strategy of expeditious delivery during the third trimester.

"Postpartum/newborn" de Quervain's tenosynovitis of the wrist

De Quervain's tenosynovitis is a common wrist ailment involving the abductor pollicis longus and extensor pollicis brevis tendons of the first dorsal compartment. Etiology is thought to be overuse or trauma. The specific entity of "postpartum/newborn" de Quervain's tenosynovitis has not been described in the orthopedic literature. Affected individuals in the setting of infant care tend to be younger (33 years) and to have bilateral involvement; they may or may not be the birth mothers. Nonoperative treatment was successful in most (77%) of the postpartum/newborn cases reviewed here; operative treatment was successful in the rest.

Distal superior cerebellar artery aneurysm presenting with cerebellar infarction: report of two cases

SUMMARY

We report two cases of aneurysm of the distal branches of the superior cerebellar artery presenting with cerebellar infarction. In both cases, the diagnosis required close correlation of the findings from different imaging techniques, as catheter angiography failed to opacify the lesions. In one patient endovascular parent vessel occlusion was performed, whereas in the second patient the aneurysm thrombosed spontaneously. We describe the clinical and radiologic presentation of these aneurysms and discuss their pathogenesis, diagnosis, and treatment.

Peripartum cardiomyopathy--a case report

Peripartum cardiomyopathy in the form of congestive heart disease of unknown etiology appears relatively rarely during the last month of pregnancy or within 5 months after delivery, and it is potentially life-threatening. This case report describes a 34-year-old female, G4P1, at 36 weeks' gestation who was admitted for cesarean section under lumbar epidural anesthesia due to twin pregnancy. She had no past history of cardiovascular diseases. However, rapid onset of dyspnea at ward and acute cardiac failure developed 15 h after cesarean section. Peripartum cardiomyopathy was diagnosed. After a 7-day intensive treatment she was discharged. Since then she was symptom-free and her two babies were doing well during a period of one more years after discharge.

[Respiratory tuberculosis and effectiveness of its treatment in some high-risk groups]

Comparative study of respiratory tuberculosis morbidity in 3 risk groups revealed its highest rates suggesting its epidemic in prisoners. There were its quite high incidence rates in pregnant and postpartum women. It was low in medical staff though it was greater than in the region's general population. Poor clinical patterns were found in former prisoners, homeless persons, and in females during gestation, and in postpartum period in particular. The outcomes of treatment were the best in medical staff. They were the worst in socially disoriented groups. Former prisoners and homeless persons had a high risk of ineffective treatment.

Vena cava thrombosis associated with nephrotic syndrome in the puerperal gestational cycle

CONTEXT

The puerperal gestational cycle is accompanied by a state of physiological hypercoagulability. Thromboembolic phenomena may occur at this time.

OBJECTIVE

To report on a clinic case involving a patient that presented a family history of thromboembolism and developed deep vein thrombosis in a lower limb and vena cava thrombosis during the puerperal gestational cycle, displaying nephrotic syndrome as the main complication.

DESIGN

Case report.

Coronary artery dissection during pregnancy and the postpartum period: two case reports and review of literature

Spontaneous coronary dissection is a rare event occurring particularly in women during the peripartum and postpartum period. Two cases related to the early postpartum period with a successful outcome are described, together with a comprehensive review of all the previously published cases. Diagnostic and therapeutic considerations of this unique clinical entity are discussed and reviewed.

Postpartum angiographic embolization for vulvovaginal hematoma. A report of two cases

BACKGROUND

Puerperal hematomas can become a life-threatening obstetric emergency. Their incidence is 1 or 2/1,000 deliveries. When mainstay methods of suture and packing fail, arterial embolization becomes an excellent alternative to definitive treatment, laparotomy.

CASES

A 32-year-old woman, para 2-0-2-2, developed extreme rectal and vulvar pain one hour postpartum. A 12 x 10-cm vulvovaginal hematoma was identified, drained, sutured and packed. Bleeding continued, blood products were administered, and selective angiographic embolization of the pudendal and inferior gluteal arteries was successfully performed. A 31-year-old woman, para 1-0-1-1, developed a left vaginal hematoma immediately postpartum. She failed vaginal packing and underwent angiographic arterial embolization successfully. The patient was discharged on the fourth postpartum day. At six weeks postpartum, neither patient had evidence of hematoma formation.

CONCLUSION

In the setting of a puerperal hematoma refractory to conventional first-line therapy, arterial embolization provides a rational, effective alternative for achieving hemostasis with minimal morbidity.

Thyroid disease in relation to pregnancy: a decade of change

Inspection of the references cited in this review indicates that much work has occurred in the area of thyroid and pregnancy during the last decade. Significant advances in our understanding of the immunology of pregnancy and the effect of thyroid disease on this process have taken place. The role of hCG in the physiology of pregnancy and its relevance to thyroid function has been an emerging theme. There is still no clear explanation for the association between thyroid antibodies and infertility or miscarriage. During the last decade a general concensus has developed in relation to the management of hyperthyroidism in pregnancy although there are still variations in antithyroid drug use at this time. The aetiological classification of congenital hyper- and hypothyroidism utilizing new technologies has opened up a new perspective on these disorders. Attention has been drawn to the importance of treating maternal hypothyroidism with adequate thyroid replacement therapy and to the possibility of impaired child neuropsychological development consequent on low maternal thyroid hormone concentration in early gestation in non iodine deficient areas. Significant advances have been made during the last decade in the description of the clinical features and in our understanding of the pathogenesis of postpartum thyroid disease. The importance of long-term follow up of selected patient groups has also been emphasized.

[Current management in pregnancy and epilepsy]

Modern treatments make possible uneventful pregnancy and successful delivery for most of the epileptic women. Major risks however remain the teratogenic effects of some antiepileptic drugs and the obstetric complications they may cause. This implies careful planning of pregnancy for women with epilepsy and alertness for possible unwanted or undiagnosed (in the early stages) pregnancy in epileptic women during their reproductive years. The authors summarize current opinions in drug selections, specific treatment regimens and the obstetrics problems during pregnancy and delivery in epileptic women.

[New methodological guidelines for the prevention and treatment of venous thromboses during pregnancy and in the puerperal period in Kuwait. Thrombophilia Clinic, Al-Adan Hospital]

The high incidence of venous thromboembolic problems among women during pregnancy and puerperium in Kuwait require a new guidelines to cope with the increased number of thrombotic events and complications in this group. Pregnant ladies should be refer red in very early trimester to a Thrombophilia Clinic where they will be checked routinely for general and special laboratory tests accordingly. They will be classified to high risk category or low risk category. The high risk category group should receive a prophylactic measures throughout pregnancy and puerperium, while the low risk group do not need further action. Those who develop venous thrombosis from any categories should be classified in the high risk category during next pregnancies.

Management of chronic myeloid leukemia during pregnancy with leukapheresis

We describe the successful treatment of a pregnant patient with chronic myelogenous leukemia in chronic phase by using only leukapheresis. Following 20 leukapheresis procedures initiated during the 13th week of gestation and performed over approximately 7 weeks, the patients white blood cell count dropped from 242,000/microl to 19,300/microl. The WBC remained stable over the ensuing 17 weeks until the time of delivery. The patient gave birth by cesarean section to a healthy 2,640 g boy at 37.5 weeks of gestation. This is the second report of the successful use of leukapheresis alone for chronic myelogenous leukemia in chronic phase during the first half of pregnancy. We conclude that where leukapheresis is available, it may provide an alternative treatment to chemotherapy or alpha-interferon, especially in light of their potential teratogenic and leukemogenic side-effects.

Recognizing, understanding, and treating postpartum thyroiditis

Postpartum thyroiditis is the most common endocrinologic disorder, with an incidence that varies geographically from 5% to 10%. It has important clinical sequelae including symptoms of hyperthyroidism, hypothyroidism, and depression. Long-term follow-up of women who experience postpartum thyroiditis reveals a high recurrence rate in subsequent pregnancies. Postpartum thyroiditis is an autoimmune disorder, and thyroid antibody-positive women in the first trimester have a 33% to 50% chance of developing thyroiditis in the postpartum period. Whether or not to screen for postpartum thyroiditis remains controversial.

Postpartum microangiopathic hemolytic anemia: cases of successful and dismal outcome assisted with plasma therapy

Microangiopathic thrombosis, thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS), seem to occur with certain stresses, including pregnancy. This report documents the clinical outcome with or without plasma therapy and dismal outcomes of two cases with postpartum microangiopathic thrombosis. One carried a pregnancy to successful cesarean delivery and suffered from postpartum TTP/HUS followed by plasma therapy-assisted recovery. Another developed postpartum TTP/HUS and was complicated with subarachnoid hemorrhage. Submission to plasma therapy should always be considered in a woman with postpartum microangiopathic thrombosis.

Acquired hemophilia A in women postpartum: clinical manifestations, diagnosis, and treatment

Acquired hemophilia A in women postpartum is diagnosed by a prolonged activated partial thromboplastin time (APTT), low plasma levels of coagulant factor VIII, and the detection of an inhibitor against factor VIII in the Bethesda assay. Effective treatment of bleeding symptoms should be based upon the clinical situation and depends on the inhibitor characteristics against human and porcine factor VIII. Immunosuppression usually does not significantly affect the disappearance of the factor VIII inhibitor antibody. The natural history of acquired hemophilia postpartum is independent of immunosuppressive treatment and featured by spontaneous disappearance of the inhibitor against factor VIII in the majority of cases.

Breastfeeding and postpartum maternal care

The early postpartum period is a time of transition for families. Breastfeeding, the optimal form of feeding for newborns, doesn't always come naturally. Medical interventions at birth can affect early breastfeeding, and close follow up of breastfeeding couplets is essential. New mothers often deal with challenges such a postpartum depression, thyroid disease, perineal pain, and other sexual concerns. Physicians can support families in this transition period to help optimize it for the mother and her baby.
