Aneuryrsm and Vascular tumors Flashcards
بسم الله عليك توكلنا وأنت نعم المولي و كفي بك وكيلا
Discuss definition of Aneurysm .
Focal dilatation of part of arterial wall or Cardiac wall in MI due to its weakness
not occur in veins Divided into true and false
True Aneurysm includes ?
1- Atherosclerotic 2-Syphilitic 3-dissecting 4-mycotic 5-congenital
My ASDCo
What is Atherosclerotic Aneurysm ?
It is True Aneurysm and it appear mostly in AbdoMnial AOrta below renal arteries and it is due to the formation of atherosclerotic plaque and detached atheroma and loss of intima and compression of media causing the focal dilation in aorta
the shape is FUSIFORM
Describe syphilitic aneurysm .
It is True aneurysm due to syphilis and it is apeearing mostly in the asednding thoracic aorta mainly TRANSVERSE arch and aortic valve it is due to Syphilitic inflammations around vasa Vasorum of the ascending thoracic aorta causing weakness of the wall ! !
فلا يكن في صدرك حرج منه !
and this leads to atheroscleroisis syphilis ?>?>?>.?
it appears as SACCULAR shape pulsating mass in the chest
Describe dissecting aneurysm .
Appear is distal aortic arch and descendig aorta
it is due to :
1-Medial necrosis موت الالياف الداعمة للاوعية المغذية هتخليها تفرقع وتطلع الدم في الجدار due to hypertension
2-Myxoid media congenital الطبقة اصبحت هلامية ضعيفة عكس الالياف الداعمة برضو هتخلي الاوعية المغذية تفرقع
3-Marfan syndrome ضعف في النسيح الضام في الجدار
Vasa Vasorum exploison due to HTN !
The descending accumulated blood cause desnding splitting if aortic wall layers
Blood in HTN may also enter from the lumen
اخطر نوع لانه الوحيد الذي يقابل مقاومة طبقة واحدة وهي advvntitia
ممكن ينفجر
عوامل مساعدة
Morphology Intramural blood between layers of the wall تصلب الشرايين يضعف الجدار متلازمة مارفان الضغط العالي
الأعراض
ألم شديد في الصدر يسمع ورا في الظهر و ينزل لتحت بمرور الوقت سكاكين بتقطع في الظهر
Describe dissecting aneurysm .
Appear is distal aortic arch and descendig aorta AS hematoma in the wall
it is due to :
1-Medial necrosis موت الالياف الداعمة للاوعية المغذية هتخليها تفرقع وتطلع الدم في الجدار due to hypertension
2-Myxoid media congenital الطبقة اصبحت هلامية ضعيفة عكس الالياف الداعمة برضو هتخلي الاوعية المغذية تفرقع
3-Marfan syndrome ضعف في النسيح الضام في الجدار
Vasa Vasorum exploison due to HTN !
The descending accumulated blood cause desnding splitting if aortic wall layers
Blood in HTN may also enter from the lumen
اخطر نوع لانه الوحيد الذي يقابل مقاومة طبقة واحدة وهي advvntitia

الأعراض

dissecting aneurysm site mention
Appear is distal aortic arch and descendig aorta
Mention causes and supporters of dissecting aneurysm .
1-Medial necrosis موت الالياف الداعمة للاوعية المغذية هتخليها تفرقع وتطلع الدم في الجدار due to hypertension
2-Myxoid media congenital الطبقة اصبحت هلامية ضعيفة عكس الالياف الداعمة برضو هتخلي الاوعية المغذية تفرقع
عوامل مساعدة
تصلب الشرايين يضعف الجدار
متلازمة مارفان مشاكل في النسيج الضام
الضغط العالي تسهل انفجار الفاسا فسورم و تدخل دم جوا الجدار من التجويف
Morphology OF DISSCETING ANEURYSM .
Morphology: Intramural blood between layers of the wall.
Mycotic aneurysm describe
it is due to weakness of vasa vasorum due to INFLAMMATIONS DUE TO
1-EMBOLI IN SBE
2-TB
and this leads to weakness of wall of small arterirs cereberal coronary mesenteric other and their dilatation as fungi
Morphology
saccular →
Thrombosis -
ruptured
Desctibe berry or congenital aneurysm .
Mostly appears in cerberal vessels and circle of wills and it is congenital and appear as Berry anurysm at the bifuractions may rupture casuing cerebral hemorrhage !
مهم جدا
Charcot bouchard aneurysm
Charcout bouchard aneurysm is dilatation in small arteries due to HTN
يعمل نزيف في المخ
Aneurism of PAN
Complications of Aneurysm Mention
CRT:
1- Compression Atrophy vertebrae
2-Ruptured vessels causing ( hemothorax - hemopericardium - blood in abdomen-intracranial Hgr )
3-Thrombosis -Coronary occlusion
لان الدم ماشي بطئ في منطقة الاتساع
False aneurysm includes:
1-Pulsating Hematoma
2-A-V fistula
Discuss Pulsating Hematoma .
It is due to hemorrhage from the artery then the output blood froms thrombosis on the wall of blood vessels and is coverd by fibrosis giving the shape of aneurysm and is pulsating with the arterial pulse
Traumatic hematoma. The wall is formed by
surrounding compressed tissue
Discuss A-V fistula
it is due to
Developmental - Trauma - inflammatory necrosis - surgery Hemodydialis
casue shunt of blood from arteries to veins increasing VR and may casue outp HF
الدوالي في الساق ليه مش بتنتشر ؟
لانها بتحصل في الاوردة السطحية ومش بتعمل جلطات انتشارية
DESCRIBE VARICOSE VEINS
Dilated Congested Elongated Tortuous veins
appear in
Superficial vein of lower limbs
portosystemic anastomosis esophageal varices»_space;,,
Aetiology :
1- Weak veins
2-High pressure (Prolonged standing and portal HTN )
Consequences are?
Thrombosis and embolism wxcept superficial veins of LL
1 - Edema
2-ruptured venules hemorrhage
3- trophic skin ulcers varicose ulcers > INFECTION>Thromboplebitis
Mention Consequences of varicose veins
Thrombosis and embolism wxcept superficial veins of LL
1 - Edema
2-ruptured venules hemorrhage
3- trophic skin ulcers varicose ulcers > INFECTION>Thromboplebitis
Mention sites of Varicose veins .
Superficial vein of lower limbs
portosystemic anastomosis esophageal varices»_space;,,
Mention Benign Vascular tumors .
HemangioMa capillary and cavernous is vascular spaces containg blood and separated by fibrous stroma
Glomangioma : Vascular spaces + Gloms cells in between forming higly cellular stroma they are heat sensitive cells and mostly appear in nail tip .
Describe Kaposi sracoma
It is malignant vasuclar tumor due to what ?
low immunity enabiling Human Herpes virus 8 to enter the boy dnf do whatever it aspires !
عبارة عن اوعية مكبوسة وخلايا مكبوسة وهو كابوسي ساركوما
Spindle malignant cells and extravascular RBCs
slit like vascular spaces
IT has 4 relations :
AIDS Related : LN and viscera
Europe : leg senile
African : LM starvation malmutirion
After transplantation : we give cortisones causing low immunity > LN and VISCERA
Angiosarcoma describe
فلا يكن في صدرك حرج منه !
It is malignant vascular tumor
and this leads to formation of connecting vascular spaces
without septa with malignant endothelial lining
occurs in skin , liver , breast !
in liver to carcinogenic chemicals like ? arsinc
