Vascular disorders
• Iran: 8.3%, Turkey: 17%, ITR-ICBD: 18%
• Any size
• Venous: more common
*superficial phlebitis, DVT, large vein thrombosis
SVC, IVC, supra-hepatic, portal vein thrombosis
cerebral venous and retina thrombosis• Arterial:
*aneurism, thrombosis

Superficial thrombophlebitis
• Most frequent type• May predict visceral involvement• Increase risk of DVT• Main symptom: localized extremity pain• May occur after venipuncture• Females are affected more than males
![Page 10: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/10.jpg)
DVT
• Males > females• More common in younger age of disease onset• Reported as an initial symptom• Critical period for development: 2-3.2 years after
diagnosis of Behcet disease• Tend to occur earlier than arterial involvement
![Page 11: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/11.jpg)
IVC thrombosis
• 15% of large vessel involvement• Should be suspected in:
* alternating venous thrombosis in lower limbs
* Recurrent venous thrombosis in one limb
![Page 12: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/12.jpg)
Budd-Chiari syndrome
• Characterized by hepatomegaly, RUQ pain, ascites, oedema of lower limbs
• Rarely, spontaneous remission• Mostly, at risk of slowly progressive hepatic
failure, • Not common
![Page 13: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/13.jpg)
SVC thrombosis
• 1.4-9.8% of venous involvement• Blockage of lymphatic circulation: chylothorax
![Page 14: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/14.jpg)
Cerebral venous thrombosis
• Main symptom: persistent headache and papilledema due to intracranial HTN, may be the presenting feature of disease
• Is not rare
![Page 15: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/15.jpg)
Peripheral artery involvement
• Marked male predominance• Any peripheral artery: femoral, popliteal, iliac and
abdominal aorta• Infrequent in carotid artery• Venous involvement is found in most patients• Occlusion is more common than aneurysm but
both is not unusual finding• Clinical presentation: asymptomatic to pulsatile
mass, back pain, painful mass, hematoma, intermittent claudication, abdominal pain, gangrene of forefoot, …
• Rate of death: up to 60%
![Page 16: Vascular involvement and clinical criteria in Behcet`s disease Presented by: Sasan Fallahi, MD Rheumatologist, Kerman University of Medical Sciences.](https://reader031.fdocuments.in/reader031/viewer/2022020720/551be11b550346af588b5e8b/html5/thumbnails/16.jpg)
Pulmonary vascular involvement
• The most sever: Pulmonary artery aneurism: leading cause of death
• Almost exclusively in males• Most frequent symptom: chest pain, hemoptysis• Association with: DVT of lower limbs, vena cava
or intra-cardiac thrombosis and aneurysms in other sites
