What is cerebral venous sinus thrombosis?

Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brain's venous sinuses. The clot keeps blood from draining out of the brain. As a result, pressure builds up in the blood vessels. This can lead to swelling and bleeding (hemorrhage) in the brain.

What is acute sinus thrombosis?

Cavernous sinus thrombosis is a blood clot in the cavernous sinuses. It can be life-threatening. The cavernous sinuses are hollow spaces located under the brain, behind each eye socket. A major blood vessel called the jugular vein carries blood through the cavernous sinuses away from the brain.

How is cerebral venous sinus thrombosis diagnosed?

Imaging studies are essential to diagnosis of CVST. The most commonly used imaging tests for CVST are magnetic resonance imaging (MRI) and computed tomography (CT) scans. The doctor may also order a magnetic resonance venogram or CT venogram of the brain.

Where is the cerebral venous sinus?

Cerebral Venous Sinus Thrombosis (CVST) is a type of rare blood clot that forms in the venous sinuses in your brain. This is a system of veins found between the layers of the dura mater -- the tough outer layer of your brain that lies directly under your skull.

Introduction

Massive administration of SARS-CoV2 vaccines has been identified as the mainstay in the control of the unprecedented coronavirus disease 2019 (Covid-19) pandemic. Cerebral venous sinus thrombosis (CVST) is a rare manifestation of cerebrovascular disease, accounting for 0.5%–1.0% of all stroke admissions.

Materials and Methods

This study was conducted in all hospital branches (Keelung, Linkou, Taipei, Taoyuan, Kaohsiung, Chiayi, Yunlin, and Fengshan) of the Chang Gung Medical Foundation (CGMF) in Taiwan. CGMF is the largest multi-institutional healthcare system in Taiwan, with more than 10% of inpatient coverage of the entire population.

Results

Between January 2017 and December 2020, we were able to identify 68, 201,15, and 103 hospitalizations from the hospitalization claims data with an ICD-10-CM code of G08, I629, I636, and I676 in any field of the discharge diagnoses, respectively. Seven hospitalizations were coded with more than one of these ICD-10-CM codes.

Discussion

We assessed the PPV of various case definitions using ICD-10-CM diagnostic codes for CVST. The PPVs of G08, I636, and I676 were found to be good to excellent when they were used alone or in combination with other relevant codes in any field of diagnosis, while the PPV of I629 was poor.

Conclusion

The PPVs of ICD-10-CM codes of G08, I636, and I676 were generally high to identify cases of CVST, while that of I629 was not. Our results support the use of Taiwan’s NHIRD to study CVST.
