Factor V and VIII deficiency treated with therapeutic plasma exchange prior to redo mitral valve replacement

A case of mitral valve repair complicated by acquired factor V deficiency

Factor V deficiency is an extremely rare hematologic disorder with an incidence of one in one million. However, the risks related to cardiac surgery employing cardiopulmonary bypass in patients with factor V deficiency are not well established. Herein, we report the case of a 71-year-old male who was incidentally diagnosed with acquired factor V deficiency underwent mitral valve repair for severe mitral regurgitation. The patient was treated preoperatively with an adrenocorticosteroid immunosuppressant therapy; the procedure was performed safely with a positive outcome.

Factor V Deficiency (Owren's Disease) in a Patient at High Risk for Transfusion-Associated Circulatory Overload and Bleeding During Laser Lead Extraction

Congenital factor V deficiency is an extremely rare abnormality and may be associated with significant bleeding as a result of trauma or surgery. Perioperative management primarily includes the administration of fresh frozen plasma to replace the deficient clotting factor. Acute administration of multiple blood products is a risk factor for transfusion-associated circulatory overload. Herein, the case of a 71-year-old man with an ejection fraction of 13% and a history of congenital factor V deficiency who was at risk for significant bleeding and transfusion-associated circulatory overload who underwent successful complex extraction of a right atrial pacing lead is reported.

Pharmacological management of rare coagulation factor deficiencies besides hemophilia

INTRODUCTION

Rare coagulation factor deficiencies are less-known disorders with variable effects on the patient's life. Management of such patients is a challenge due to the paucity of evidence-based data, more so when patients with these rare disorders encounter a more rare, related condition, like inhibitor development or thrombosis.

AREA COVERED

A comprehensive literature search related to RCFDs and management was performed in PubMed in order to discuss therapeutic options and challenges, prophylaxis, management of minor and major surgeries, obstetric and gynecological complications, inhibitor development, and thrombosis.

EXPERT OPINION

Although significant changes have occurred in the management of RCFDs in recent years, more evidence-based studies besides expert opinion are needed for optimal management.

The use of prophylaxis in the treatment of rare bleeding disorders

Rare bleeding disorders (RBDs) are a heterogeneous group of coagulation factor deficiencies that include fibrinogen, prothrombin, α₂-antiplasmin, plasminogen activator inhibitor-1, and factors II, V, V/VIII, VII, X, XI and XIII. The incidence varies based upon the disorder and typically ranges from 1 in 500,000 to 1 per million population. Symptoms vary with the disorder and residual level of the clotting factor, and can range from relatively minor such as epistaxis, to life threatening, such as intracranial hemorrhage. Rapid treatment of bleeding episodes in individuals with severe bleeding phenotypes is essential to preserve life or limb and to prevent long-term sequelae; therapeutic options depend on the deficiency and range from plasma-derived (eg, fresh frozen plasma, prothrombin complex concentrates, factor X concentrate) to highly purified and recombinant single factor concentrates. The rarity of these disorders limits the feasibility of conventional prospective clinical trials; instead, clinicians rely upon registries, published case reports/series and experience to guide treatment. In some disorders, long-term prophylactic therapy is administered in response to the bleeding phenotype in an individual patient or based on the known natural history and severity of the deficiency. Intermittent prophylaxis, surrounding surgery, pregnancy, labor, and menstruation may be required to prevent or control excessive bleeding. This review summarizes therapeutic options, guidelines, recommendations and observations from the published literature for long-term, surgical, gynecological, and obstetric prophylaxis in deficiencies of fibrinogen; prothrombin; factors II, V, V/VIII, VII, X, XI and XIII; combined vitamin-K dependent factors; α2-antiplasmin; and plasminogen activator inhibitor 1. Platelet disorders including Glanzmann's thrombasthenia and Bernard-Soulier syndrome are also addressed.

Literature review of apheresis procedures performed perioperatively in cardiac surgery for ASFA category indications

BACKGROUND

Perioperative therapeutic plasma exchange in patients with cardiovascular diseases poses several challenges, including alterations in intravascular volume, serum electrolytes, the coagulation cascade, and drug pharmacokinetics.

METHODS

This review article summarizes different indications of plasma exchange for patients requiring cardiac surgery based on reported case reports and case series.

RESULTS

The most common reported indication is plasma exchange for the management of allosensitized cardiac transplant candidate patients in combination with immunosuppressive regimens, which increases the likelihood of obtaining a cross-match-negative allograft, improving post-transplant clinical outcome. The second most common indication is for patients with a history of heparin-induced thrombocytopenia syndrome that permits the use of heparin in cardiopulmonary bypass in an urgent cardiac surgery. Less common indications are restoration of clotting factors for patients with congenital bleeding disorders or removal of cold agglutinins. No severe complications were described in reported cases.

CONCLUSION

Therapeutic plasma exchange is an effective and safe procedure that could be performed preoperatively and intraoperatively in urgent cardiac surgery for the management of antibody-mediated disorders including allosensitized cardiac transplant candidate patients or patients with heparin-induced thrombocytopenia syndrome.
