Stroke can be treated through endovascular procedure, this treatment involves placing a catheter / long tube into the brain for removal of clot that is causing the stroke. Endovascular treatment must be done within six to nine hours of the onset of a stroke by the experts, depending on the location. Endovascular procedure in stroke treatment can restore blood flow within a few minutes in the brain.

Endovascular Surgery and Vascular Surgery are both modalities of treatment is to treat vascular disease. Endovascular Surgery describes a minimally invasive approach whereas Vascular Surgery is more invasive and involves incisions, which is more in surgical nature. Vascular specialists are those who can perform both vascular surgical and Endovascular procedures.

Usually there are no major complications or risks of endovascular treatment while treating blood vessels but in some cases procedural complications including access site problems like vessel / nerve injury, hematoma, aneurysm and groin infection can occur in approximately 4 to 5 % of people undergoing endovascular procedures . Additional lesion related complications can occur in 2 to 3% of patients which includes Vasospasm, arterial perforation and dissection, device detachment/misplacement. Some other complications include anaesthetic / contrast related problems like aggravation of renal failure. 

Candidate eligibility for endovascular surgery is dependent on multiple factors like extent or type of blockage as well as patient factors like age, surgical risk or comorbid conditions.

Like any other procedure or surgery, endovascular surgery does have potential complications and serious consequences which may include blockage of the blood flow through the stent.

Most patients stay in the hospital for only 1 to 3 days after endovascular surgery. Mostly recovery in endovascular surgery is faster and with less pain than traditional open surgery.

No, comparatively endovascular surgery is less painful procedure than traditional open surgery, and also offers other advantages including faster recovery, less infection, comfortable and less stress on the heart and fewer risks for patients with other medical conditions.
