Materials and Methods: In this observational study, spanning 4 years (December 12–December 16), a total of 442 patients presented with an acute ischemic stroke/transient ischemic attack (TIA) at our study centers. 14/546 (3.2%) of these patients had magnetic resonance angiography (MRA)/computed tomography angiography (CTA) evidence of extracranial dissections. All cases underwent detailed clinical evaluation on arrival, and data were recorded on a predesigned stroke pro forma. Contrast MRA was done on arrival in all cases as part of a standard stroke protocol, and CTA was done only if MRA was inconclusive. The pattern of the vessel involved and morphology of vessel dissection was analyzed as per a standard radiology protocol. All the cases were managed with short-term anticoagulation using low-molecular-weight heparin followed by oral anticoagulants for 3–6 months. All cases were followed up for 1–2 years and the functional outcomes were recorded using the modified Rankin Scale (mRS). Results: There were 11 males and 3 females in the study, and the mean age was 45.1 years (range = 27–65 years). Focal neurological symptoms occurred in all these patients (10 patients had a stroke, and 4 had TIA). Nearly 64.2% of these (9/14) were stroke in young (age <45 years). The internal carotid artery was the most common vessel involved in 85.7% (12/14) cases. Of the ten patients with completed stroke, a good functional outcome (mRS 1–2) was seen in 8/10 (80%). Digital subtraction angiography and revascularization procedures were needed only in a minority of cases 3/14 (21%).\ Conclusion: This hospital-based study highlights the importance of suspecting arterial dissections in young strokes of unexplained etiology, and offering optimum anticoagulant therapy in the acute phase, to achieve good long-term outcomes. }, volume = 9, issn = {0976-3147}, issn = {0976-3155}, url = {https://doi.org/10.4103/jnrp.jnrp_540_17}, doi = {10.4103/jnrp.jnrp_540_17} }
