As a modern neurosurgical technique, minimally invasive surgery for pituitary adenoma, despite its advantages such as less trauma, still carries certain risks.

Does minimally invasive surgery for pituitary adenoma carry risks? How is anesthesia administered?

I. Risks of Minimally Invasive Surgery for Pituitary Adenoma

1. Intracranial Infection

Because minimally invasive pituitary surgery is often performed through the nasal cavity, which is not a completely sterile environment, there is a risk of intracranial infection. This infection may be retrograde, meaning bacteria can enter the cranial cavity through the surgical pathway, leading to infection. Once an infection occurs, it can seriously affect the patient's prognosis and may even be life‑threatening.

2. Cerebrospinal Fluid (CSF) Rhinorrhea

During surgery, if the nasal mucosa or the skull base mucosa does not heal properly, CSF rhinorrhea may occur. CSF rhinorrhea not only increases the risk of infection but may also lead to low intracranial pressure and cause a series of symptoms. In addition, if CSF rhinorrhea is not properly managed for a prolonged period, it may result in serious consequences such as pneumocephalus or brain herniation.

3. Diabetes Insipidus

The pituitary stalk may be injured during surgery, leading to diabetes insipidus. Diabetes insipidus causes the patient to excrete large volumes of urine, resulting in electrolyte disturbances, and in severe cases may lead to disability or death.

4. Internal Carotid Artery Injury

The internal carotid arteries often run on both sides of the pituitary adenoma. If dissection is inadequate or if the tumor erodes into the artery, injury to the internal carotid artery may occur. Once the internal carotid artery is injured, bleeding is often difficult to control, and ligation of the carotid artery may even be required, which can lead to severe consequences such as massive cerebral infarction.

5. Other Risks

Complications such as postoperative intrasellar hematoma, epistaxis, meningitis, and hypopituitarism, although relatively low in incidence, may also have a serious impact on the patient's health if they occur.

II. Anesthesia Method for Minimally Invasive Pituitary Surgery

The anesthesia method for minimally invasive pituitary surgery is generally general anesthesia. General anesthesia ensures that the patient remains in a deep sleep during the procedure, thereby reducing pain, minimizing agitation, and ensuring the smooth progress of the surgery. The specific application of general anesthesia in minimally invasive pituitary surgery includes the following:

1. Anesthesia Induction

Before the operation begins, the anesthesiologist administers intravenous anesthetic agents to rapidly induce sleep. At the same time, to ensure a patent airway, orotracheal intubation is performed.

2. Anesthesia Maintenance

During the procedure, the anesthesiologist continuously administers anesthetic and muscle relaxant agents based on the patient's vital signs and surgical requirements, maintaining a deep sleep state and adequate muscle relaxation.

3. Anesthesia Monitoring

Throughout the surgery, the anesthesiologist closely monitors the patient's vital signs, including heart rate, blood pressure, respiration, and oxygen saturation. Any abnormalities are promptly addressed.

4. Anesthesia Emergence

After the operation, the anesthesiologist discontinues the anesthetic agents and waits for the patient to recover spontaneously. During emergence, the patient is closely observed to ensure a smooth transition.

Does minimally invasive surgery for pituitary adenoma carry risks? How is anesthesia administered?

Although minimally invasive surgery for pituitary adenoma has many advantages, it still carries certain risks. To reduce surgical risks and ensure optimal outcomes, physicians must perform thorough preoperative evaluations and preparations, and strictly adhere to operative standards during the procedure. At the same time, general anesthesia, as the primary anesthetic technique for minimally invasive pituitary surgery, ensures patient safety and comfort during the operation. However, all surgeries carry inherent risks, and patients should fully understand these risks and make informed decisions when considering surgery.

Note: INC International Neurosurgeon Circle's International Neurosurgical Advisory Group (WANG) includes many internationally renowned professors with superb surgical skills and extensive successful case experience, such as Professor Sébastien Froelich (France), former Chairman of the Skull Base Surgery Committee of the World Federation of Neurosurgical Societies (WFNS). He specializes in endoscopic endonasal resection of skull base tumors, performing minimally invasive surgeries via neuroendoscopy for complex brain tumors including chordomas, craniopharyngiomas, and pituitary adenomas. His "chopsticks" technique in endoscopic surgery not only improves the tumor resection rate but also leads to better prognoses for tumor patients.

The INC International Neurosurgical Advisory Group is a physician consortium composed of neurosurgery professors from developed countries around the world; each member professor has made significant contributions to international neurosurgery in their respective fields. For patients with brain tumors or cerebrovascular diseases in complex locations such as the brainstem, thalamus, corpus callosum, spinal cord, or pineal region who seek higher‑quality and more extensive safe surgical resection options internationally, remote consultations with INC international professors are available.
