Clinical features of Trousseau's syndrome with multiple acute ischemic strokes

Abstract

Background: Trousseau's syndrome or migrating thrombophlebitis can cause venous or arterial thrombosis; however, multiple acute ischemic strokes (MAIS) caused by Trousseau's syndrome are rare. The aim of this study was to analyse the clinical features of Trousseau's syndrome with MAIS and to improve the awareness and the knowledge of this disease.

Methods: Clinical data from fifteen patients who were diagnosed as Trousseau's syndrome with MAIS in Rizhao People's Hospital from January 2017 to April 2020 were collected and analysed. The clinical data included the following: patients' basic information (including gender, age, underlying diseases, and tumour stage), laboratory results, imaging features, treatment regimens, and short-term prognoses were collected.

Results: The mean age was 65.5 years, with thirteen males and two females. Most patients (11/15) had a history of smoking and (or) drinking. The average score of NIHSS was 2.13. 6 of the 15 patients first presented with ischemic stroke and then found the primary tumour. Most common types of primary tumour was lung cancer (11/15), and other types of primary tumour were gastric adenocarcinoma, renal cell carcinoma, oesophageal adenosquamous carcinoma, and cholangiocarcinoma (one in each). All the 15 patients showed different levels of increase of D-dimer. The increase in CRP appears in 10 of the 15 patients. Various tumour markers were increased in the 15 patients, especially for CYFRA-211, all the patients of which were higher than normal. All of the 15 patients had multiple vascular territory lesions in DWI, and most lesions were near the cortex areas. Only 4 of the 15 patients (26.7%) occurred with peripheral venous thrombosis. Thirteen patients were given low molecular heparin for anticoagulant therapy, of which 9 patients were improved in short-term while 4 patients were not.

Conclusion: Trousseau's syndrome with MAIS was associated with old-age male, smoking and (or) drinking history, low NIHSS score, increased D-dimer, CRP and tumour markers, and lesions near the cortex areas with multiple vascular territories in DWI. Patients with these features should be alert of malignant tumour. Most common types of primary tumour were lung cancer. Treatment with low molecular heparin may be effective in short term.
