DC-CRP: Deep Cerebral Venous Thrombosis, Clinicoradiological Profile, and Treatment Outcome in Indian Population-A Tertiary Care Experience.

BACKGROUND

Deep cerebral venous thrombosis (DCVT) is an uncommon cause of stroke with diverse predisposing factors, clinical presentations, imaging findings, and functional outcomes, which makes the diagnosis of DCVT even more challenging.

MATERIALS AND METHODS

Retrospective observational study (December 2018 to January 2023). Cases with imaging data suggestive of DCVT were included. The neuroradiological assessment was performed using multimodality imaging to determine the location of parenchymal changes and the number of deep veins involved in isolation or with the superficial dural venous system. Clinical variables were tabulated.

RESULTS

Of the 206 cases with CVT in the study period, 27 had DCVT (13.1%), of which four (14.8%) had isolated DCVT (male-to-female ratio 13:14; mean age = 33.4 years). Hyperhomocysteinemia ( = 11) is the most common risk factor associated with it. The most common presentations were headaches ( = 27) and focal motor deficits ( = 13). Raised intracranial tension (ICT) was present in almost half of the study population ( = 14). Mean and median modified Rankins score (mRS) at the time of discharge were 2.0 and 1, respectively. The most common deep vein involved was the straight sinus (SS) ( = 25), followed by the internal cerebral vein ( = 23). The mean and median mRS after 3 months from discharge were 0.3 and 0, respectively.

CONCLUSION

A knowledge of diverse clinical presentations in DCVT, its neurovascular anatomy, and imaging characteristics with prompt diagnosis and timely interventions can assist in attenuating the risk of acute complications and long-term sequelae. Extensive deep grey matter involvement in DCVT is associated with neurological manifestations like altered sensorium and motor deficits, with increased severity of illness as measured by the mRS score.
