Abstract

Objective: We present a case of intraprocedural device malfunction related to the JET 7 Xtra Flex reperfusion catheter during mechanical thrombectomy.

Case presentation: A 92-year-old man presented with sudden right hemiparesis with a National Institutes of Health Stroke Scale score of 22. His left middle cerebral artery (M1) was occluded, and emergency mechanical thrombectomy was performed. After partial recanalization was achieved, angiography through a JET 7 Xtra Flex was attempted. After manual injection of contrast media via a 10-mL syringe through the JET 7 Xtra Flex, the catheter moved, jumping forward, and the distal tip of the catheter expanded and ruptured. This resulted in intracranial vessel damage and subsequent patient death.

Conclusion: Contrast media must not be injected through the JET 7 Xtra Flex. If contrast media needs to be injected for angiography during mechanical thrombectomy with a reperfusion catheter, it should always be through the guide catheter.

Keywords: JET 7; acute ischemic stroke; combined technique; complication; mechanical thrombectomy.
