[Endoscopic polypectomy in benign adenoma and in early colo-rectal lesions].

The Authors report their results in 219 patients who underwent endoscopic polypectomy for benign adenomatous polyps and early colorectal cancer. This is safe and curative technique associated with low-risk of complications and in an ideal therapy to prevent the development of colorectal cancer. In fact, nowadays, dysplasia-carcinoma sequence has been described. All polyps were histologically identified and the grade of dysplasia always detected.

Abdominal Takayasu's aortitis, the middle aortic syndrome and atherosclerosis. A critical review.

To review the current status of clinical, pathological and arteriographic aspects of abdominal Takayasu's aortitis (TA). Personal experience with 86 patients with TA and review of the literature is the basis of this report. The diagnostic significance of primary versus secondary atherosclerosis is described in this communication and the arteriographic differential diagnostic guidelines are provided to separate abdominal TA from abdominal atherosclerosis.

Angiographic diagnosis of small intestinal intussusception.

The outstanding angiographic features of small intestinal intussusception are: (a) abrupt disappearance of mesenteric vessels at the neck of the intussusception with crowding of the vasa recta; (b) appearance of long collateral channels at the neck of intussusception; (c) angulation and retraction of major intestinal branches; (d) reversal of the course and angulation of the invaginated mesenteric vessels; (e) overlapping of the mesentery vessels by branches of the intussuscipiens; (f) abrupt change in the appearance of the vasa rectae of the distended intussuscipiens and the distal nondistended small intestines.

Pancreatic pseudocysts presenting as thick-walled renal and perinephric cysts.

Posterior extension of a pancreatic pseudocyst should be considered in the differential diagnosis of a thick-walled renal or perinephric cyst seen on infusion pyelography with tomography. Opacification of the wall of a pancreatic pseudocyst by this technique has not been reported previously and lack of knowledge of this possibility can lead to mistaken diagnosis and the possibility of an unnecessary exploratory operation, particularly when angiography is inconclusive and a gastrointestinal series is negative or equivocal. The mechanism of opacification of the wall of a pancreatic pseudocyst is discussed. Parasitization of the renal capsular arteries by a pancreatic pseudocyst can further compound the difficulty of diagnosis.

Takayasu's arteritis: an unrecognized cause of pulmonary hypertension.

Pulmonary arteritis and secondary pulmonary hypertension are common in patients with Takayasu's arteritis. These sequelae of arteritis have not been previously emphasized in the literature. In some patients, particularly young and middle-aged women, disproportionately severe involvement of the pulmonary arteries may be the cause of pulmonary hypertension of unknown etiology.

The spectrum of arteriographic findings in Osler-Weber-Rendu disease.

In Osler-Weber-Rendu syndrome, visceral organs are frequently involved in addition to cutaneous and mucous membranous lesions. Detailed arteriographic investigation of 5 patients with this abnormality disclosed characteristic angiodysplastic lesions involving the lungs, liver, spleen, pancreas, gastrointestinal tract and mesentery. Arterial and aortic aneurysms appear to be an integral part of this abnormality. Common to angiodysplastic lesions is a variable degree of arteriovenous shunting. The arteriographic characteristics and the hemodynamic significance of major visceral arteriovenous shunts in hereditary hemorrhagic telangiectasia are discussed.

Iatrogenic embolization of the superior mesenteric artery: arteriographic observations and clinical implications.

Following sudden occlusion of the superior mesenteric artery, there is a characteristic and predictable pattern of blood flow through the instantaneously activated collateral channels. On the left, the first patent jejunal or ileal branch utilizes the central tier of the mesenteric arcades to revascularize the distal trunk of the occluded superior mesenteric artery. On the right, the anastomotic connection between the middle colic, right colic, and ileocolic arteries provides an efficient collateral pathway. These two collateral channels supplement each other and the distal trunk of the occluded superior mesenteric artery is usually rapidly reconstituted. Superior mesenteric artery embolization is frequently an asymptomatic event. There appears to be a variable tolerance of cardiac and non-cardiac patients to the effect of superior mesenteric embolization. Non-cardiac patients may tolerate embolization of the superior mesenteric artery quite well. Cardiac patients frequently respond with an ischemic crisis. The site of embolization is another determining factor. An embolus below the origin of the middle colic artery provides an incomparably more favorable hemodynamic situation than an embolus proximal to the origin of this vessel. The excellent tolerance of our group of patients to superior mesenteric embolization appears to be closely related to these two main factors.

Takayasu's arteritis and congenital coarctation of the descending thoracic and abdominal aorta: a critical review.

A critical reappraisal of the clinical, arteriographic, and pathologic features of Takayasu's arteritis and so-called congenital aortic coarctations at atypical sites is presented. It is concluded that as an isolated cardiovascular abnormality, cases of atypical congenital coarctations of the descending thoracic and abdominal aorta are probably rare. The majority of atypical aortic coarctations previously reported in the United States and Europe as congenital lesions apparently represent unrecognized cases of Takayasu's arteritis.
