Superior vena cava syndrome as a paraneoplastic manifestation of soft tissue sarcoma

Superior vena cava syndrome-induced hemoptysis

Superior vena cava (SVC) syndrome resulting from obstruction of the blood flow to the superior vena cava is rarely reported to present with life-threatening hemoptysis. The pathogenesis and the underlying mechanism are still not well described in the literature. We report a unique case of a 27-year-old man known to have end-stage kidney disease (ESKD) on hemodialysis that presented with shortness of breath and life-threatening hemoptysis that developed during the dialysis session. Computerized tomography with contrast (CTPA) confirmed the presence of a large, calcified thrombus within the SVC along with the formation of multiple collaterals which was diagnostic for SVC syndrome. Attempts for revascularization and stenting failed, and the patient had a prolonged and stormy course while admitted, including difficult alternative dialysis access that unfortunately resulted in death eventually. Here we are highlighting the importance of recognition of hemoptysis as a presentation of SVC syndrome by explaining the underlying pathogenesis and possible management options.

Recurrent Superior Vena Cava Syndrome in a Patient with Sarcoidosis and Pancreatic Adenocarcinoma: A Case Report and Literature Review

Background: Superior vena cava (SVC) syndrome may result from extravascular compression or intravascular obstruction such as thrombosis. Recurrent venous thrombosis is typically associated with a hypercoagulable state such as malignancy, and inheritable or acquired coagulopathy. Sarcoidosis is a derangement of the immune system, and it has been associated with malignant diseases and hypercoagulation. The association of pancreatic cancer and sarcoidosis with SVC syndrome has not been reported previously. Here, we present a case of recurrent venous thrombosis causing SVC syndrome in a patient with pancreatic ductal adenocarcinoma and underlying thoracic sarcoidosis. Methods: The patient's electronic health record was retrospectively analyzed. Results: A 66-year-old woman with pancreatic adenocarcinoma was treated with neoadjuvant chemotherapy followed by Whipple procedure, before developing tumor recurrence in the liver. Her treatment course was complicated with repeated incidents of venous thrombosis in the presence of a central venous catheter leading to recurrent SVC syndrome, which resolved with anti-coagulation. Conclusions: This case raises a plausible inter-relationship between sarcoidosis, pancreatic cancer, and hypercoagulable state. We suggest that patients with multiple risk factors for developing venous thrombosis should be carefully monitored for any thrombotic event, and they may benefit from prophylactic anti-coagulation.

The Face Is the Mirror of the Soul. The Cardiovascular Physical Exam Is Not Yet Dead!

Cardiac pathology can be congenital or acquired with underlying genetic predispositions. In this era of medicine there is a concern that the comprehensive physical examination doctors prided themselves on is becoming a lost art. Research studies have also revealed a decline in physical examination skills. The full clinical cardiovascular examination is indeed quite complex and does take significant time to master. It is critical that physicians be competent in the physical exam. Not identifying subtle clinical findings leading to missed or delayed diagnosis which can lead to significant morbidity and mortality. In this paper we intend to highlight the clinical cardiovascular findings that may be detected on patients even before initiating the physical exam. The head and neck visual examination may be quite revealing.

Sore throat turned to be a bronchogenic carcinoma with superior vena cava syndrome

Superior vena cava (SVC) syndrome is a group of symptoms caused by complete or partial obstruction of the flow of blood through the SVC. The obstruction is, in most cases, caused by the formation of thrombus or infiltration of a tumour through the vessel wall. The result is venous congestion that creates a clinical situation relating to increase in the venous pressure in the upper part of the body. Symptoms commonly associated with vena cava syndrome include cough, dyspnoea, swelling of the neck, face and the upper extremities and dilation of the chest vein collaterals. In this paper, we examine the case of a 50-year-old man who presented to the emergency department with ‘sore throat’ which can be easily misdiagnosed as a case of uncomplicated acute pharyngitis. It was a real challenge to diagnose our patient as SVC syndrome caused by bronchogenic carcinoma.
