Are “paradoxical emboli” really paradoxical?

Pulmonary tumor embolism (PTE) is a rare manifestation of cancer. It is characterized by the presence of tumor cell emboli in the pulmonary arterioles and capillaries leading to an elevation of pulmonary vascular resistance. The ante-mortem diagnosis is difficult. We report a case of PTE associated with recurrent breast cancer that presented with neurological symptoms due to paradoxical cerebral embolism.

Paradoxical Emboli

Pulmonary arteriovenous malformations (PAVM) are a group of vascular anomalies of lung which present with variable clinical symptoms. Most patients with PAVM are asymptomatic but it can cause dyspnea on exertion, paradoxical emboli to brain causing various central nervous system complications like stroke and brain abscess, hemoptysis and rupture. The age at the presentation can range from 1st to 7th decade but the majority of patients present before the age of 30 years. PAVM is strongly associated with hereditary haemorrhagic telangiectasis which presents with epistaxis, mucocutaneous telangiectasias and AV malformations of various organs. In our case series, we have patients ranging from 3 yrs to 75 years with presentation ranging from asymptomatic to exertional dyspnea, hemoptysis and neurological complications.

Purpose: To report a case of paradoxical emboli to multiple visceral vessels treated with both mechanical (AngioJet device) and pharmacological (urokinase) thrombolysis. Methods and Results: A 72-year-old man presented with a 48-hour history of symptomatic right renal ischemia, which was treated with heparinization. Five days later, an abrupt creatinine elevation prompted arteriography, which demonstrated thromboembolism of the superior mesenteric artery (SMA) and both renal arteries. The AngioJet aspiration device was employed to successfully remove the clot from the SMA; urokinase infusion restored flow to the left kidney. At the 16-month follow-up evaluation, the patient was normotensive without medication and had a stable creatinine (1.4 mg/dL). Conclusions: Because of its speed and minimal morbidity, the AngioJet device may be an attractive alternative to surgical embolectomy or pharmacological thrombolysis in highly selected cases of acute visceral artery thromboembolism.
