On November 10, 2011, a neurosurgeon attempted to clip an aneurysm that his female patient, age 49, was diagnosed with in October, 2011. During this procedure the patient sustained a subarachnoid hemorrhage. Intraoperative angiography suggested a probable shearing of the aneurysm at the vessel neck. Following the procedure, a neurosurgeon continued to monitor the aneurysm. On December 5, 2011, a CT angiogram revealed what was likely a pseudo aneurysm at the base of the previously clipped aneurysm. On the morning of December 30, 2011, during a routine, scheduled follow-up of Mrs. DiCapua, the neurosurgeon ordered a CT angiogram. This study revealed that a “lobulated collection of contrast materials is now visible along the lateral margin of the aneurysm clips at the junction of the horizontal and descending portions of the left anterior cerebral artery.” The neurosurgeon personally reviewed this study. Instead of admitting the patient for investigation of the lobulated collection of contrast material referenced above, the neurosurgeon discharged Mrs. DiCapua to home. Later that evening she sustained yet another subarachnoid hemorrhage. As symptoms of the brain bleed evolved, her family initially took her to the nearby emergency room and she was then sent back to the defendant Chicago area hospital. As a result of this conduct, the patient suffered a brain injury.
