A 46 year old gentleman from north Karnataka, came to us  with  complaints of left sided weakness and difficulty in speaking since 10 days before arrival.

On examination -he was  Conscious alert oriented. No motor or sensory deficits.


MRI brain stroke protocol showed MCA territory watershed infarcts with right MCA high grade stenosis.

DSA digital subtraction angiogram showing  >95% focal stenosis with reduced flow into distal branches of M2M3.

After preparing  and explaining benefits and risks  we planned for  Stenting of MCA.

MCA is a major brain vessel one on each side right and left. When stenting is advised , it is a minimally invasive procedure. There is no need to open the skull no blood loss like routine craniotomy.  Small thin wires  and tubes little larger than our hair are inserted into the vessel in the thigh and which reaches the brain and where stenting is applied in the narrowed vessel.

In Cath lab, right femoral puncture was done, right femoral sheath was placed . Using guide wires, micro wire and micro catheter  right MCA is reached.   We did MCA stenting(2.25mmx8 mm) brain vessel.



Patient tolerated procedure well.

No complications.

Post op CT scan was normal. No Bleeding or stroke.

A Transient Ischemic Attack (TIA) is  a stroke which will reverse in 24 hours with or without any treatment,  it is also known as a mini-stroke. It is very important to find out the cause of mini stroke.

Mini stroke is a warning sign of major stroke. In elderly commonly  there will be fat accumulated in the vessels(atherosclerotic vessels)  in neck and brain  there may be significant disturbance in the blood flow into the brain . If there is transient interruption in blood flow there will be momentarily stoppage of brain function and causes ischemia and mini stroke,  there will be reversal of stroke after establishment of circulation to brain.

Symptoms of TIA(Mini stroke)

  • Facial weakness
  • Weakness in limbs
  • Speech dysfunctions
  • Dizziness.
  • Vision dysfunction transiently
  • Diagnosis by
  • Duplex scan
  • CT scan brain
  • MRI brain
  • MRA angiogram
  • ECHO
  • Perfusion scan brain.
  • DSA

Learning points –

  1. TIAs will predict the future stroke by 15 %
  2. TIA are warning sign  of major stroke ,which can be prevented by  correct treatment .
  3. About 30 -40 % of people who have TIA can have major  stroke within one year
  4. Interventional Surgery for stroke- MCA stenting, carotid Stenting, mechanical thrombectomy for acute stroke.
