Intracranial blood flow has some anatomical variation such is absence of posterior communicating artery on one side. Moyamoya disease (MMD) is classically defined by pruning of blood vessels after circle of Willis and further tapering. MMD can be unilateral and seen over 70% in female patients. Bilateral MMD usually present with intraventricular hemorrhage (IVH) while unilateral with subarachnoid hemorrhage. We present a complex neurocritical care patient with unilateral MMD and IVH. The complication of nasopharyngeal hemorrhage led to challenging neurocritical care course.
A 61-year-right-handed female patient with remote history of seizure disorder and pulmonary histoplasmosis presented with high grade IVH. She was intubated and transfer to neurocritical care unit. On arrival, an emergent external ventricular device (EVD) was inserted. Her CT-angiogram (CTA) of brain showed absence of flow in left internal carotid and posterior cerebral artery. There was robust collateral flow consistent with chronic unilateral MMD. A formal cerebral angiogram confirmed CTA findings of unilateral MMD. Left external artery (ECA) angiogram was done to review the collateral and confirm the presence of adequate superficial temporal artery for future bypass. EVD was gradually weaned and taken out after 10 days and she was extubated on the 14th day. At 48 hours post extubation, she began with bleeding in the oral cavity, not being able to identify the area of bleeding. She was emergently intubated for aspiration and bronchoscopy confirmed fresh blood in the right lower lobe without any active bleeding. The thought was oral trauma from prolonged initial intubation led to this hemorrhage. She was given red blood cell and open tracheostomy was performed next day. She was weaned off the ventilator and plan was to start acute inpatient rehab. Two days post-tracheostomy, patient developed projectile bright red epitaxies. Immediate nasal packing was done though no active bleeder was seen and tracheotomy site was stable. At this stage, a multidisciplinary phone conference was arranged between neurocritical care, vascular neurosurgery, neurointerventioanl radiology, and otolaryngology. Cerebral angiogram was reviewed. It confirmed that extensive dilated and enlarged ECA branches are source of bleeding. Further reviewed showed that left eye blood flow was via ECA rather ICA [Figure 1]. Endovascular intervention was out of question as it would high likely lead to lost blood flow to left eye and blindness. Another brief episode led to reduction of SBP, which was kept under 160 mmHg, to under 130 mmHg. After this change, she stopped having any bleeding. Plan was to get her through the rehabilitation and revisit neurovascular revascularization planning in the near future.
