peripheral vascular diseases
- Vasculitis
- Inflammation of the blood vessel wall
- Nonspecific symptoms of inflammation (e.g., fever, fatigue, weight loss, and myalgias)
- Symptoms of organ ischemia—due to luminal narrowing or thrombosis of the inflamed vessels
- Symptoms of organ ischemia—due to luminal narrowing or thrombosis of the inflamed vessels
- Nonspecific symptoms of inflammation (e.g., fever, fatigue, weight loss, and myalgias)
- Inflammation of the blood vessel wall
- HTN
- PRIMARY HTN
- . HTN of unknown
etiology (95% of cases)
- Risk factors include age, race (increased risk in African Americans, decreased
risk in Asians), obesity, stress, lack of physical activity, and high-salt diet.

- . HTN of unknown
etiology (95% of cases)
- SECONDARY HTN
- HTN due to an identifiable etiology (5% of cases)
- Renal artery stenosis is a common cause (renovascular hypertension)
- Renal artery stenosis is a common cause (renovascular hypertension)

- ATHEROSCLEROSIS
- Risk factors :
- Arterial HT... Tobacco smoke... Hereditary... Endocrine.. Reduced physical activity...
Obesity... Male gender... Age ...stress

- Causes of intermittent claudication
- Most commonly, intermittent (or vascular or arterial) claudication is due to peripheral arterial
disease which implies significant atherosclerotic blockages resulting in arterial insufficiency.
- Most commonly, intermittent (or vascular or arterial) claudication is due to peripheral arterial
disease which implies significant atherosclerotic blockages resulting in arterial insufficiency.
- Complications :
- aneurysmal dilatation and thrombo –embolism.
- Ischemic Heart Disease & Myocardial Infarction
- chronic ischemia, infarction.
- ischemic bowel disease, infarction.
- intermittent claudication
- aneurysmal dilatation and thrombo –embolism.
- Diagnosis
- Magnetic resonance angiography... Duplex ultrasonography
- Magnetic resonance angiography... Duplex ultrasonography
- Risk factors :
- arterioloscelrosis
- A. Narrowing of small arterioles; divided into hyaline and hyperplastic types
- Hyaline arteriolosclerosis is caused by proteins leaking into the vessel wall, producing vascular
thickening; proteins are seen as pink hyaline on microscopy.
- Hyperplastic arteriolosclerosis
- involves thickening of vessel wall by hyperplasia of smooth muscle ('onion-skin appearance).
- 1. Consequence of malignant hypertension
- 2. Results in reduced vessel caliber with end-organ ischemia
- involves thickening of vessel wall by hyperplasia of smooth muscle ('onion-skin appearance).
- MONCKEBERG MEDIAL CALCIFIC SCLEROSIS
- A. Calcification of the media of muscular (medium-sized)
arteries; nonobstructive
- B. Not clinically significant; seen as an incidental
finding on x-ray or mammography
- A. Calcification of the media of muscular (medium-sized)
arteries; nonobstructive
- A. Narrowing of small arterioles; divided into hyaline and hyperplastic types
- Aortic dissection
- A. Intimal tear with dissection of blood
through media of the aortic wail
- B. Occurs in the proximal 10 cm of the aorta (high stress
region) with preexisting weakness of the media
- Most common cause is hypertension (older adults); also
associated with inherited defects of connective tissue
(younger individuals)
- D. Presents as sharp, tearing chest pain that radiates to the back
- D. Presents as sharp, tearing chest pain that radiates to the back

region) with preexisting weakness of the media
- A. Intimal tear with dissection of blood
through media of the aortic wail
- Aneurysm
- THORACIC ANEURYSM
- Due to weakness in the aortic wall. Classically seen in
tertiary syphilis; endarteritis of the vasa vasorum
results in luminal narrowing, decreased flow, and
atrophy of the vessel wall. Results in a 'tree-bark'
appearance of the aorta
- C. Major complication is dilation of the aortic valve root,
resulting in aortic valve insufficiency
- C. Major complication is dilation of the aortic valve root,

- Due to weakness in the aortic wall. Classically seen in
tertiary syphilis; endarteritis of the vasa vasorum
results in luminal narrowing, decreased flow, and
atrophy of the vessel wall. Results in a 'tree-bark'
appearance of the aorta
- ABDOMINAL AORTIC ANEURYSM
- Balloon-like dilation of the abdominal aorta; usually
arises below the renal arteries, but above the aortic
bifurcation
- D. Major complication is rupture, especially when > 5 cm in
diameter; presents with triad of hypotension, pulsatile
abdominal mass, and flank pain
- D. Major complication is rupture, especially when > 5 cm in

- Balloon-like dilation of the abdominal aorta; usually

- THORACIC ANEURYSM
- Bruits
- Carotid bruits
- Carotid stenosis
- Carotid stenosis
