“…They noticed a large amount of blood in the basal cisterns at the time of transcranial approach to remove a pituitary adenoma and reported marked spasm of both internal carotid arteries, as well as the anterior and middle cerebral arteries. There were also a few reports of cerebral vasospasm after surgery for pituitary macroadenoma without pituitary apoplexy (18, 20). These reports concluded that the most probable cause of vasospasm after transsphenoidal tumor removal was subarachnoid hematoma in the basal cisterns.…”

A 41-yr-old man was admitted with acute headache, neck stiffness, and febrile sensation. Cerebrospinal fluid examination showed pleocytosis, an increased protein level and, a decreased glucose concentration. No organisms were observed on a culture study. An imaging study revealed pituitary macroadenoma with hemorrhage. On the 7th day of the attack, confusion, dysarthria, and right-sided facial paralysis and hemiparesis were noted. Cerebral infarction on the left basal ganglia was confirmed. Neurologic deficits gradually improved after removal of the tumor by endoscopic transnasal transsphenoidal approach. It is likely that the pituitary apoplexy, aseptic chemical meningitis, and cerebral infarction are associated with each other. This rare case can serve as a prime example to clarify the chemical characteristics of pituitary apoplexy.

“…There is risk of damage to vessels directly involved with the tumor, commonly those of the internal carotid arteries (ICA), anterior cerebral arteries (ACA) as well as vessels outside of the surgical field of view, but adherent to the tumor capsule [131]. Failure to appreciate the tumor-vessel relationships may result in vasospasm and hemorrhage during or after trans-sphenoidal resection [133–136]. …”

Pituitary adenomas are among the most common central nervous system tumors. They represent a diverse group of neoplasms that may or may not secrete hormones based on their cell of origin. Epidemiologic studies have documented the incidence of pituitary adenomas within the general population to be as high as 16.7%. A growing body of work has helped to elucidate the pathogenesis of these tumors. Each subtype has been shown to demonstrate unique cellular changes potentially leading to tumorigenesis. Surgical advancements over several decades have included microsurgery and the employment of the endoscope for surgical resection. These advancements increase the likelihood of gross-total resection and have resulted in decreased patient morbidity.

“…Mechanical spasm of the carotid arteries can be seen due to the dissection around these arteries, overpacking with haemostatic products or direct injury. This spasm distinctly can cause arterial insufficiency and stroke [5].…”

“…Although rare, injury to the internal carotid artery (ICA) is a devastating complication commonly resulting death or serious disability. This injury can result in direct hemorrhage, spasm [5], thrombosis of ICA or cavernous sinus [30,43], embolism and delayed false aneurysm [2,6,7,12,17,18,21,26,27,30,31,43] formation of carotico-cavernous fistula [1,39].…”

Overview of vascular complications of pituitary surgery with special emphasis on unexpected abnormality

Arterial bleeding during transsphenoidal surgery for pituitary adenoma is known complication. This usually happens due to rupture of intracavernous carotid or delayed hemorrhage due to the carotico-cavernous fistula and/or pseudoaneurysm. There is also evidence that cavernous carotid aneurysms may occur with pituitary tumors, yet largest series failed to demonstrate any link between aneurysm formation and pituitary tumors. Usually such an aneurysm rupture results in formation of carotico-cavernous fistula. However, pituitary apoplexy and even epistaxis have been reported. In this paper we present a patient with recurrent pituitary adenoma and cavernous carotid artery aneurysm, which caused significant hemorrhage during the surgery. Although retrospective analysis of MRI disclosed that the patient had the aneurysm before the first surgery, it remained silent until the second operation. Therefore neurosurgeons should be very susceptive to any signal changes on preoperative MR images, especially in recurrent cases, where normal anatomical relations are disturbed by fibrotic tissue. Also, we reviewed the vascular complication of pituitary surgery based on the literature.
