Treatment of AAA/Dissecting Aneurysms

Recently, the Medical Director of our Air Ambulance Program asked me about the use of Beta Blockers and other “sheer force” reducing medications for the treatment of Abdominal Aortic Aneurysms. It was his belief, that in Abdominal

Surgical diseases of the veins

Veins are the vessels that the blood is returned to the heart and lungs to replenish its oxygen supply. Several conditions may affect the veins, thereby modifying the normal venous return.

Surgical diseases of the arteries

When any body part is deprived of its oxygen supply, the part dies, the condition known as gangrene. This may occur in any body strucĀ­ture in total or in part. In certain body areas correction of impaired

AAA + other pathology: surgical judgement

There is no ‘hard and fast right answer’. Every situation is different and must be carefully individualized. This type of question is a favorite for board examiners both in General Surgery as well as those sitting for

Chronic Venous Insufficiency

The basic abnormality in patients with chronic venous insufficiency is elevation of venous pressure. With calf muscle pump dysfunction, valvular reflux, blood pools in the lower extremities and venous hypertension occurs, leading to venous hypertension. Outflow obstruction

Gastrointestinal Ischemia Syndromes

The celiac axis and mesenteric arteries are the principal sources of blood supply to the stomach and intestines, with the two internal iliac arteries adding collateral flow to the distal colon. The anatomic collateral interconnections between these

Arteriovenous Fistulas

Arteriovenous fistulas, often called “malformations,” may be congenital or acquired. Abnormal communications between arteries and veins occur in many diseases and affect vessels of all sizes and in many locations. In congenital fistulas, the systemic effect is

Peripheral Arterial Aneurysms

Popliteal artery aneurysms account for 70% of peripheral arterial aneurysms. Like aortic aneurysms, they are silent until critically symptomatic. However, unlike aortic aneurysms, they rarely rupture. The presenting manifestations are due to peripheral embolization and thrombosis. Popliteal

Acute Arterial Occlusion

Acute arterial occlusion characterized by the abrupt onset of severe pain, coldness, numbness, motor weakness, and absent pulses in the involved extremity. When ischemia persists, motor and sensory paralysis, muscle infarction, and gangrene become irreversible in a

Signs of Arterial Insufficiency

Decreased amplitude of the pulse denotes proximal stenosis and arterial insufficiency . It is unusual for collateral flow to be sufficient to produce a pulse distal to an occluded artery. The surgeons generally use the right common
