Q

Carotid Endarterectomy (CEA)

A

A surgical procedure that may reduce a patient’s risk of stroke
During a carotid endarterectomy, the carotid artery is exposed and the plaque buildup is removed

41
Q

What is a stroke?

A

an interruption in the blood supply that can lead to cell death and an interruption
of function This can be caused by an arterial blockage, leading to the more common ischemic stroke or by hemorrhage into the brain itself, leading to the more fatal hemorrhagic stroke.

42
Q

What % of strokes are men/women?

A

60% women, 40% men

43
Q

Stroke us the Number X cause of death in the US?

A

5

44
Q

Every X minutes someone dies of a stroke?

A

4 Minutes

45
Q

What is the leading cause of an Ischemic stroke?

A

Atherosclerosis

46
Q

Atherosclerosis

A

Hardening of the arteries that supply the head and neck (carotid and
vertebral arteries), causing narrowing and blockage of these vessels

47
Q

Label

A
48
Q

Endovascular Treatment for ICAD

A

The lesion is first pre dilated
with the Gateway ® PTA Balloon Catheter, then the Wingspan ® Stent System, mounted on a catheter tip, is unsheathed and the stent is deployed to form a scaffold to hold the artery open

49
Q

What are the two shapes of these Aneurysms?

A
50
Q

What percent of aneurysms develop in the anterior circulation and posterior circulation of the brain?

A

Anterior Circulation - 85%, posterior circulation - 15%

51
Q

Treatment options of Vasospasm

A

Medical Therapy with pharmacological agents to increase the blood pressure and improve blood flow to the brain
Placement of a catheter in a cerebral artery to allow direct infusion of pharmacological agents to dilate the artery
Placing a balloon catheter into the vessel to dilate it

52
Q

Angioplasty

A

Placing a balloon catheter into the vessel to dilate it

53
Q

Test

A

Test

54
Q

Arteriovenous Malformations (AVMs)

A

abnormal direct connections between arteries and veins that form a tangle of dilated blood vessels that bypass normal brain tissue and directly shunt blood from the arteries to the veins

55
Q

Nidus

A

The actual site of the abnormal
communication in AVMs

56
Q

Arteriovenous Fistula (AVF)

A

A congenital or acquired direct connection of variable length between an artery and a vein, with the absence of an intervening nidus. Born with AVFs, AVMs are caused.

57
Q

Computerized Tomography (CT)

A

the imaging modality most often used in diagnosing and imaging stroke. CT scanning is a specialized X ray examination in which a transaxial image is obtained from multiple angular projections

58
Q

Computerized Tomographic Angiography (CTA)

A

involves injecting a dye into a vein to provide
contrast, which allows images to be taken of the blood vessels

59
Q

3 Types of drugs that interfere with the normal blood coagulation process

A

antiplatelets, anticoagulants, or thrombolytic (clot breaking) drugs.

60
Q

Name Antiplatelet drugs

A

Aspirin, Plavix

61
Q

Name Anticoagulant drugs

A

Heparin, Coumadin, ReoPro, Integrilin, Aggrestat

62
Q

Name Thombolytics drugs

A

Streptase, Abbokinase, Activase, Retavase

63
Q

What are the three methods of treating stroke from least invasive to most invasive?

A

Medical management, Endovascular Treatment, surgical intervention

64
Q

Carotid endarterectomy (CEA)

A

During a carotid endarterectomy, the carotid artery is exposed and the plaque buildup is removed.

65
Q

Intracranial Atherosclerotic Disease (ICAD)

A

is the narrowing and hardening of the arteries inside the brain due to the formation of plaque inside of the vessel.

66
Q

Atherosclerosis

A

often develops at branch points or curving portions along extracranial and intracranial large arteries where blood flow is slowed and more turbulent.

67
Q

Typical intracranial atherosclerotic lesions present primarily in five locations

A

Main trunk of the MCA

Carotid siphon

Mid-portion of the basilar artery

Vertebrobasilar junction

Distal vertebral artery.

68
Q

intracerebral hemorrhage (ICH)

A

is a hemorrhage into the tissue deep within the brain.

69
Q

subarachnoid hemorrhage (SAH)

A

occurs outside of the parenchyma and into the subarachnoid space (the space between the brain and the skull).

70
Q

What happens when an AVM burst?

A

hemorrhagic stroke occurs

71
Q

Glasgow Outcome Score

A

evaluates a patient on individual overall social capability (or dependence)

72
Q

Modified Raymond Scale

A

measures the risk of a coiled aneurysm regrowing and/or re-rupturing

73
Q

Hunt & Hess Grading System

A

classifies patients with intracranial aneurysms (SAH) according to surgical risk

74
Q

Fisher Grade

A

classifies a SAH based on the appearance on a CT scan

75
Q

Endovascular embolization

A

uses a catheter to reach the location of the abnormality before injecting some material to seal the blood vessel.

76
Q

Stent Assisted coiling steps

A

The catheter enters the parent vessel of the aneurysm.
The stent begins to expand at the location of the aneurysm.
The stent lines the walls of the parent vessel.
The coil catheter is fed through the stent into the aneurysm.
Coils are released into the aneurysm.
The stent and the coils remain in place.

77
Q

Balloon occlusion

A

occlusion balloon is a temporary device which is inflated in the parent vessel, in front of the neck of the aneurysm, causing occlusion of both neck and parent vessel as coils are advanced into the aneurysm

78
Q

Coiling

A

Involves inserting a catheter into the aneurysm, and then inserting tiny platinum coils through the catheter and deploying them into the aneurysm

79
Q

Stent assisted coiling steps

A

The stent lines the walls of the parent vessel.
The coil catheter is fed through the stent into the aneurysm.
Coils are released into the aneurysm. The stent and the coils remain in place.
