Retroesophageal right aortic arch.

Right aortic arch with left descending aorta and a retroesophageal aortic segment is an uncommon congenital vascular malformation which may cause symptoms of compression from a vascular "ring." The presence of this malformation may be suspected by the findings on barium swallow and the diagnosis confirmed by angiocardiography. Surgical intervention may be necessary in patients who have severe symptoms.

Blood flow measurements in the iliac arteries by an improved angiographic cinedensitometric technique.

The blood flow of iliac arteries was measrued by means of an improved angiographic chindensitometric technique. This consists of cineradiographic recording of contrast injection into the iliac arteries, followed by optical analysis of the "washout" phase of the contrast material at selected sites. In 25 pateints without perpheral vascular disease, undergoing abdominal angiography for different reasons, the blood flow measruements in left iliac arteries were within the limits of 371-766 ml

A comparison between partial and complete ligation of the inferior vena cava for the prevention of recurrent pulmonary embolism.

Interruption of the inferior vena cava is the definitive surgical measure for the control of pulmonary emboli. There is, however, some controversy as to whether the preferred treatment is complete or partial interruption. This report summarizes our experience with 49 patients who underwent partial ligation, using a technique developed in our Department, and 66 patients, who underwent complete ligation of the inferior vena cava. The incidence and severity of sequelae due to venous stasis in the legs were less in the group that underwent partial interruption.

False aneurysm of the left atrium after closed mitral commissurotomy: diagnosis by cineangiocardiogrpahy. Report of one case treated surgically.

A case of false aneurysm of the left atrium after closed mitral commissurotomy which was demonstrated by cineangiography is here reported. It is believed that the false aneurysm resulted from a tear of the left appendage which accidentally occurred during the surgical procedure. The diagnosis was suspected in plain chest X-ray and fluoroscopy. Angiography demonstrated the presence of a false aneurysm of the left atrium which was confirmed at surgery.

Determination of the pressure drop across an arterial stenosis utilizing angiocinedensitometry.

A method is presented for an evaluation of the hemodynamic significance of a stenotic lesion in the arterial tree.Twenty-three patients were examined with arteriosclerosis obliterans and intermittent claudication of the same severity. Flow velocity data obtained by angiodensitometry and viscosity values calculated from the hematocrit were inserted into the Poiseuille's flow formula to obtain the pressure drop across a stenotic lesion in the left external iliac artery. By the same way, the pressure gradient was calculated in 33 "normal" subjects.The normal pressure gradient along the external iliac artery varied between 23 to 110 dynes/cm(2) (52 ± 24 dynes/cm(2) for mean and S.d), and the normal resistance to flow was 6.08 ± 4.1 dyne sec/cm(5)).Stenotic lesions of similar dimensions gave widely varying pressure drops (114-4,736 dynes/cm(2)) (mean and S.d 1,309 ± 1,224 dynes/cm(2)) indicating a difference in the hemodynamic significance of the various lesions. These values were significantly different (p(t) < 0.001) from the normal values. The resistance across these stenotic lesions ranged between 21 to 768 dyne sec/cm(5) (196 ± 192 dyne sec/cm(5)) for the mean and S.d and this was significantly different from the normal group; p(t) < 0.001.Direct measurement of blood viscosity coupled with angiocinedensitometry at rest and after forced vasodilatation should provide an accurate means of determining the relative significance of a stenotic lesion and distal vessel disease in a given patient on blood flow to the leg.
