What is ischemia stroke?

A stroke occurs when the blood flow in part of your brain is blocked, Just a few minutes, the starved brain cells begin to die.

Normally, the brain receives blood via two major pairs of arteries, which branch throughout brain tissue and supply your brain cells with a constant flow of oxygen, glucose and nutrients necessary for their functions.

Ischemic Stroke is an artery in your brain narrows or completely blocked preventing normal blood flow. The blockage may be caused by a blood clot, also called a thrombus which forms in an unhealthy artery in the brain. The lack of blood flow causes the tissue and the artery supplies to become starved or ischemic.

Similarly, the blockage may be due to an embolus, a blood clot that forms elsewhere in the body, travels to the brain. The embolus lodges in a narrowed artery and obstructs blood flow.

Osteoporotic Collapse Fracture at Lumbar Spine

A 84 years old lady suffers from Osteoporotic Collapse Fracture at L1 lumbar spine loading to the kyphotic deformity and stress on vertebral body 2 months' of persisting severe back pain, could not sleep well and walk without pain; This was diagnosed as Osteoporotic Vertebral Compression Fracture. 

Proposed treatment were Kyphoplasty and Vertebroplasty

  • Vertebroplasty

Under the pin holes procedure the tamp is inserted through the pedicle into the vertebral body.  The collapsed fracture and vertebral bodies are strengthened by acrylic cement bone shape are rebuilt with less angulation and more stronger bone.

  • Kyphoplasty

By inserting the inflatable bone tamp through a 2-3 cm mini wound balloon in inflated, thereby compressing the cancellous bone and restoring vertebral height. Thereafter, the cavity created by balloon is filled with acrylic cement. In this case, due to the kyphotic deformity Kyphoplasty was proceeded before Vertebroplasty in order to restore the vertebral height first Under local anesthesia patient's vertebral height was restored by the inflated balloon.

Once acrylic cement was instillated to strengthen the vertebral body and correct its kyphotic angle the persisting severe back pain immediately vanished. Bone shape were rebuilt with more stronger bone to prevent collapse and angulation with kyphotic changes.

Minimally Invasive Neurosurgery for Spine

The spine is made up of small bony segments called vertebrae. These vertebrae are categorized into cervical or neck vertebrae, thoracic (upper back), lumbar (lower back) and sacrum. 

When this cartilage in the center of the disc protrudes through small tears in the hard-outer covering of the disc, the nerves passing through the spinal cord can become compressed or pinched, causing severe pain and deformity. 

This is known as disc herniation.

Minimally Invasive Microdiscectomy or METRx Discectomy uses microscopic or endoscopic techniques to access and remove this herniated disc, and relieve pressure on the compressed nerves.

Trigeminal Neuralgia

Due to impingement from an ectatic basilar artery that with its course deviated much from the normal midline position, far far away to the left lateral region to compress the Trigeminal nerve.

Every single impulse has brought patient excruciating pain at face, teeth & jaw.  Such pain has already disturbed her speech, swallowing, work & social life for years.

Big ICA
Cerebral Aneurysm

Patient, without any symptom, underwent a detailed body check for her brain.

 

Investigation revealed a hidden Big ICA Cerebral Aneurysm of 7-8mm size. Doctor need to treat the Aneurysm before it ruptures, so as to prevent severe bleeding stroke (Subarachnoid Hemorrhage) from happening.

 

Treatment: Minimally Invasive Endovascular Neurovascular Surgery Surgery Time: 1 Hour Hospitalisation: 1-2 Day

ACDF

ACDF is a minimally invasive surgery. A small incision of 2 to 3 cm was made at the front of Patient's neck, following the horizontal neck wrinkle. Under the microscope and with the navigation of X-Ray, the Neurosurgeon carefully removed the diseased cervical intervertebral disc and spurs, with high accuracy and movement of less than two millimetres, to decompress the central and cervical nerves. Thereafter, the Neurosurgeon implanted an artificial cervical disc to fill the gap between the two vertebrae in order to stabilize the cervical spine.
