In arterial hypertension the peripheral resistance is uniformly raised throughout the area of the greater circulation, and it is not increased in the splanchnic area to any greater extent than in other tissues. AUTHORS. Baylin, George J.: Abdominal Aorta.

The collateral circulation is described in a patient, male, aged 34 years, who had a clot with calcification in the abdominal aorta just distal to the orifices of the renal arteries. The most important collateral channel was the colic anastamosis. The superior mesenteric artery and its middle colic branch were almost as large as the aorta, and joined directly with the equally enlarged left colic branch of the inferior mesenteric artery. Other channels of collateral circulation were the somewhat enlarged and tortuous internal mammaries which joined the inferior epigastric arteries on either side. The last three pairs of intercostal arteries were enlarged and tortuous and made numerous connections with other vessels. These connections were important, but ,subordinate to the anastomosis between the two mesenteries. NAIDE.

This article describes the technique for ligation and retrograde injection of varicose veins of the leg and the two tests commonly used for determining the competency of the valves of the communicating veins. The author states that the commonest sites for a venous blowout are just above and below the knee and in midthigh. The presence of pelvic tumor, active inflammation in the groin, and uIcers are contraindications for surgical treatment. Where there has been ulceration and scar formation, a Kondalion procedure is d.one, which is followed by a skin grafting procedure that incapacitates the patient for a period of eight weeks. MCGOVERN.
