Abstract

Awake craniotomy is a surgical operation similar to any conventional craniotomy while the patient is awake during the procedure. Awake Craniotomy is one of the most preferred techniques for operations of excision of tumors which involve or are close to the eloquent regions of the brain. This technique of craniotomy allows the neurosurgeons to test the brain region before incision / excision along with a regular check on the patient’s functionality during the surgery. An awake Craniotomy minimizes the risk of the patient during the operation. An old industrial worker was suffering from repeated seizures since 2014. The series of radiological investigations revealed an increasing left frontal region occupying lesion. The lesion was very close to the area of speech and right side limbs. To prevent this loss of speech and weakening of right side limbs of the patient, team carried out the Awake Craniotomy and the patient was discharged after a week’s observation and his speech was normal along with right side limbs movement.

Background

Awake craniotomy is a method of performing brain surgery where in the patient is given local anesthesia and intravenous anesthesia to keep him calm and pain free. It’s different from the usual anesthesia where mainly different gasses are used as a sedative and a deep anesthesia is achieved. In such critical cases, it is very important that the patient and relatives understand the pros and cons of the surgery and co-operate accordingly.

Case Presentation

A 42-year-old gentleman who is an industrial worker was suffering from repeated seizures since 2014. A series of radiological investigations revealed an increasing left frontal space occupying lesion since 2014; features suggestive of Glioma. The lesion was very close to the area of speech (as it was involving the dominant side – the working side for a right-handed person) and right side limbs. In case, a complete excision with good clearance of the tumor had been attempted as there was risk of loss of speech and weakening of right side limbs due to the position of the tumour. To prevent this loss of speech and weakening of right side limbs of the patient, Dr. Manish Kumar, MBBS, DNB (Neurosurgery) carried out the Awake Craniotomy with his team of doctors and technicians. The risk of loss of speech and right-side limb weakness with the immediate need for the surgical excision was explained by the team to the patient and his relatives and a possible safer option of awake craniotomy was discussed.
Craniotomy lasted for around three hours and was successful with patient co-operation. The tumour was removed satisfactorily; however the surgery had to be stopped for a while as patient’s verbal response had developed slowness. The limb response was unchanged. The patient’s speech was saved through the awake craniotomy technique of surgery. Post surgery, the patient has regained his speech and limb power back to normal.

Discussion

According to Dr. Manish, awake craniotomy is a difficult yet preferred surgery during operations for excision of tumors which involve or are close to the eloquent regions of the brain. The patient is regularly monitored for movement and speech during the surgery and if in case patient’s verbal response or activities is reduced, the surgery has to be stopped. The limb response remains unchanged post successful surgery. The patient’s speech can be easily saved through awake craniotomy technique of surgery. Post surgery, the patient has regains speech and limb power back to normal.

Conclusion

Post surgery, the patient is very well and is also neither having any issues with the limbs movement or with speech. He is eating well and is able to talk properly and monitored by his regular visits.

Declarations

The case study is presented with the consent of the patient and his family members. The Medical team at the Park Group of Hospitals including doctors, MD and MS were also taken prior approvals for the case study.

 

Awake Craniotomy

  • Awake Craniotomy

A surgical procedure for tumour close to the functionally important part of brain

– By Dr. Manish Kumar MBBS, DNB (Neurosurgery)

An awake craniotomy is a surgical operation carried out similarly to any conventional craniotomy however in this surgery the patient is awake during the procedure. Awake Craniotomy is one of the most preferred techniques for operations for excision of tumors which involve or are close to the eloquent regions of the brain. This technique of craniotomy allows the neurosurgeons to test the brain region before incision / excision along with a regular check on the patient’s functionality during the surgery. An awake Craniotomy minimizes the risk for the patient during the operation.

Awake Craniotomy Process

A drip is inserted in patient’s body for the purpose of giving local anesthesia when the patient is in the anesthetic room. The local anesthesia comforts and relaxes the patient body after which the patient is taken to operation theatre where the Neuronavigation system is used to mark areas for incisions (cuts). Through the line incision, small amount of hair would be shaven off for clear incision and to avoid infection. The patient will be in a slightly numb state however being able to hear surrounding noises and move limbs. After the incision is done the brain area is exposed Cortical Mapping is performed.

“Establishing the relationship between various structures of the brain and their functions, Cortical Mapping is a technique used in neurosurgery to determine which parts of a diseased brain may be safely excised.”

Post operation and removal of tumour the bleeding is stopped the thick membrane around the brain is closed with the help of sutures. Mini plates are used to replace the bone flap and to close scalp. The skin is stapled to close the wound and apply a head bandage.

Post Awake Craniotomy

The recovery period is much shorter for the patients of awake craniotomy compared to conventional craniotomy. The patient is able to consume food and liquid and move around. The discharge is usually the same day after surgery or after a day once the neurosurgeon confirms. It takes few weeks to completely recover after any major surgery. In case of Awake Craniotomy, for first few weeks, the patient might suffer from headaches which can be controlled with general painkillers. There are chances of dizziness, and it is must to rest properly. A little exercise or walk is however generally preferred.

Consult your doctor in case, you see following symptoms:

  • Progressively worsening headaches
  • Fits
  • Fever & Rashes
  • Wound problems
  • Weakness or Numbness
  • Increasing drowsiness

Complications after Awake Craniotomy Surgery

The risks for the Awake Craniotomy are similar to that of conventional surgery, however there is also a chance of seizures during the surgery which might require the awake surgery to be transformed into conventional surgery with general anesthesia. Surgeries are always risky and while the awake surgery is considered to be a safer option, the slight risk involved depends on the factors like size, location and the type of tumour along with patient’s generic health and medical history.

Complications after awake surgery include, however not exclusive to:

  • Temporary or permanent paralysis of limbs or loss of speech
  • Blood clot
  • Brain swelling
  • Infection
  • Fits

Abstract

“En plaque meningioma refers to a specific meningioma macroscopic appearance characterised by diffuse and extensive dural involvement, usually with extracranial extension into calvarium, orbit, and soft tissues. These tumours are thought to have a collar-like or sheet-like growth along the dura mater, different from the usual globular meningioma.”* This type of brain tumour is highly vascular and involves risky operation. Being a very rare type of tumour, this needs intensive care. A 45 year old woman with a progressive increasing headache on the right side of the brain for last years, who was also misdiagnosed by a private hospital in Sonepat, visited Park Hospital Panipat. The team at Park Hospital Panipat started the treatment with MRI and brain investigations wherein the En-Plaque Meningioma was diagnosed. There was pain and bulginess in both eye balls due to the tumour and weakness on the left side. The patient was discharged after a week of intensive observation and once we saw recovery signs in her with the ability to move smoothly her limbs.

Background

En-Plaque Meningioma is a rare type of brain tumour and requires intensive care. This is one of the slow growing benign tumours which is attached to the dura and are made up of neoplastic meningothelial cells. These are more common in Western World reporting around 24-30% cases. Meningioma en plaque represents a morphological subgroup within the meningiomas defined by a carpet or sheet-like lesion that infiltrates the dura and sometimes invades the bone. Histopathological features of meningioma enplaque are similar to that of usual meningiomas; however, it is sometimes difficult to predict the behavior in individual cases. Extra-cranial meningiomas form 1-2% percentages of all meningiomas. ** The en plaque variants commonly involve fronto-parietal, juxtaorbital, sphenoid wing, diffuse calvarial or rarely spinal region. *** Due to difficulty in complete resection, the recurrence rate of en plaque meningiomas is higher than the usual counterpart. **** These tumors are also more prone to develop malignant change (11%) when compared to intracranial meningiomas.

Case Presentation

A 45 year old woman visited Park hospital Panipat for an OPD consultation with Dr. Anil Arya wherein he studied the MRI reports and after brain investigations, he diagnosed a rare brain tumour. The lady had progressive increasing headache on the right side of the brain for last 5 years. However, for last 2 years there was pain and bulginess in both eye balls. The patient visited a private hospital in Sonepat for the treatment wherein the CT head was performed and based on the same she was misdiagnosed with Subdural Hematoma. During the operation, the doctor confirmed that the case is of Brain tumour. She was then referred to GB Pant Hospital in New Delhi for further treatment. However, she did not receive any treatment or response; thereafter she contacted Dr. Anil Arya at Park Panipat. After explaining the complexity of the surgery and the poor prognosis during and after the surgery, with due permissions, the patient was operated on 27th July 2017. The tumour mass was completely removed from the brain with craniotomy. Post operation, the patient is conscious oriented with signs of difficulty in limb movement.

Discussion
As per Dr. Anil Arya, “The surgery was very complicated and could have risked the life of the patient as well.”

Conclusion

Post surgery, the patient is very well and is also not having any issues with the limbs movement and is also not experiencing any limb weakness.

Declarations

The case study is presented with the consent of the patient and his family members.

  • Park Hospital, Panipat successfully completed a rare type brain tumor surgery

Dr. Anil Arya a highly experienced neurosurgeon at the superspecialty hospital performed a successful neurosurgery for En plaque meningioma and gave a healthy new life to the patient.

Gurgaon, Haryana: The multi super-speciality hospital of Park Group, Panipat announces to have successfully operated an en-plaque meningioma through a large craniotomy with complete excision of tumour.

A 45 year old woman visited hospital for an OPD consultation with Dr. Anil Arya wherein he studied the MRI reports and after brain investigations, he diagnosed a rare brain tumour. The lady had progressive increasing headache on the right side of the brain for last 5 years. However, for last 2 years she also had mild weakness in left upper & lower limbs with pain and bulginess in both eye balls. The patient visited a private hospital in Sonepat for the treatment wherein the CT head was performed and based on the same she was misdiagnosed with Subdural Hematoma. During the operation (Burr hole surgery), the doctor confirmed that this case is of Brain tumour.

According to Dr. Anil, this surgery was very complicated as the type of tumour diagnosed is highly vascular and is very risky to operate. On 27th July 2017, Dr. Arya operated the patient at Park Hospital Panipat and excised complete tumour mass from her brain through a large craniotomy.

Dr. Anil Arya stated that, “Post surgery the patient is fully conscious, oriented with no signs of limb weakness or any other problems.” He further added that, the complication and the poor prognosis of during and after surgery was explained to the patient and the family.
