Аннотация
PURPOSE: To highlight the diagnostic and therapeutic challenges associated with the treatment of a patient with superior vena cava syndrome and a coexisting coagulopathy.
CLINICAL FEATURES: This case report describes a bone marrow transplant patient with graft versus host diseases (GVHD) who was admitted to our intensive care unit with bronchiectasis complicated with nosocomial pneumonia. When he was recovering from pneumonia after prolonged ventilatory support, he developed superior vena cava (SVC) syndrome due to mediastinal lymphadenopathy. The diagnosis was delayed due to associated confounding clinical factors. Because of the rapid deterioration in patient's condition, immediate tissue diagnosis of mediastinal lymph nodes and re-canalization of vena cava by stenting were our priority. He had many other medical problems such as thrombocytopenia, deranged coagulation profile, old cerebral infarction with hemiplegia, seizure disorder and cardiac arrhythmias which complicated the treatment plan. USG guided biopsy followed by stenting of the SVC was done after discussing the risks and benefits with patient's relatives. But, he had bleeding from biopsy site due to deranged coagulation profile. Again for the same reason, he was not given any anticoagulants. Within 24 hours the stent was blocked by clot which was diagnosed by the deteriorating clinical features and repeat CT scan. Then he was given enoxaparin in therapeutic dose and the clot cleared within a day possibly partly due to enoxaparin and partly coagulopathy.
CONCLUSION: In a bone marrow transplant patient with GVHD, the associated complications can confound the diagnosis of SVC syndrome. Physician has to show high degree of suspicion as it may develop even if patient has coagulopathy due to other factors such mediastinal lymphadenopathy. SVC stent may clot even if the patient has coagulopathy. So, it is advisable to defer the invasive diagnostic procedures such as mediastinal lymph node biopsy till the patient is well stabilized after the stent placement in SVC as it will prevent further use of anticoagulants. Enoxaparin may be helpful in the treatment of stent thrombosis in such patients with multiple complications.
