Aesthetic surgery of the arm. Part I.

Aging factors of the upper arm, elbow, forearm, and hand have been studied to afford an understanding of aesthetic changes that occur in aging. Arm and hand roentgenograms of females, aged 10 to 70 years, were studied and the ratio between the superior and inferior part of the upper arm was calculated. This ratio, the coefficient of Hoyer, increased progressively from 1:1.0 at 10 years of age to 1:2.2 at 70 years. The laxity of the lower arm was calculated with a grasping tonometer and showed a progressive increase from 0.5 cm at 10 years of age to 4.0 cm at 70 years. Changes in the elbow and hand were also noted.

Collateral blood supply to an autotransplanted kidney.

Collateral lumbar arterial blood supply to an autotransplanted kidney was angiographically documented in a patient with bilateral Wilms' tumor and postoperative transplant renal artery stenosis. During autotransplantation, most collateral pathways are interrupted. The development of a collateral circulation after autotransplantation may be postulated to begin with a vascular response to postoperative inflammation and adhesions. The small anastomotic pathways so formed may then dilate in response to ischemia resulting from renal artery stenosis.

Focal angiographic findings in renal transplant rejection.

The angiographic signs of renal allograft rejection are usually diffusely seen throughout the kidney. Three cases of focal rejection are presented including one with histologic confirmation. Possible etiologic mechanisms are discussed. The presence of focal findings at angiography should not rule out the diagnosis of rejection.

Calcified venous thrombosis of the lower extremities.

The radiographic appearance of dense, linear calcifications in the soft tissues of the lower extremities in the region of the superficial femoral, greater saphenous, and popliteal veins is described. These calcifications are suggestive of venous thrombosis. In the appropriate clinical setting, confirmatory venography should be performed.

Right aortic arch with left descent.

A right aortic arch may descend either to the right or left of the spine. When the aorta crosses from right to left posterior to the esophagus, the findings on plain chest film and barium swallow studies may simulate those of a mediastinal mass, especially in older patients. Although aortography is definitive, computed tomography can accurately display the retroesophageal aorta, allowing rapid and hazard free diagnosis.

Cerebellar atrophy: the differential diagnosis by computerized tomography.

Seven patients with cerebellar atrophy were studied by computerized tomography. The radiographic findings were varied. They included enlargement of the lateral cisterns, loss of superior cerebellar vermian substance with prominence of the superior cerebellar cisterns, and fourth ventricle enlargements. The patterns of posterior fossa atrophy may suggest the etiology.

Benign pneumoperitoneum following median sternotomy incision.

Because of the close anatomic relationship of the pericardium, diaphragm, and peritoneal cavity, a benign pneumoperitoneum may occur following median sternotomy incision and cardiac surgery. The pneumoperitoneum results from inadvertent opening of the peritoneal cavity during the initial surgical incision or during the subsequent cardiac surgery. It is generally of no significance to the patient, although it must be distinguished from pneumoperitoneum occuring secondary to intraabdominal pathology or to retrograde dissection of extraalveolar air in patients on ventilatory support. Two illustrative cases are presented.

Diagnosis of cor triatriatum by echocardiography.

The echocardiographic findings in a case of cor triatriatum are described. The diagnosis was suggested by a normal anterior mitral valve echo and a dense band of echoes posterior to the aortic root and within the body of the left atrium; it was documented at cardiac catheterization and proved surgically. Echocardiography is an important diagnostic aid in assessing pulmonary venous obstruction in children.

Echocardiographic assessment of the severity of aortic stenosis in children and adolescents.

The magnitude of ventricular hypertrophy in response to afterloading is determined by wall stress, with wall thickness increasing in proportion to ventricular load until systolic wall stress is normalized. With use of echocardiographic measurements of left ventricular end-systolic wall thickness (Ws) and cavity transverse dimension (Ds), the pressure constant k was calculated in 16 patients without left heart obstruction according to the formula k = P-Ds/Ws. The mean value for k was 225 +/- 6.7 (standard deviation) mm Hg. From this value, left ventricular pressure was estimated in 13 patients with aortic stenosis aged 4 to 17 years using the formula P = k-Ws/Ds. No subject had evidence of cardiac failure. Peak systolic aortic pressure difference (delta P) was calculated by subtracting cuff-measured brachial arterial peak systolic pressure from the estimated left ventricular pressure. Excellent correlation was obtained between the estimated delta P and that found at cardiac catheterization (r = 0.89). In two patients, echocardiographic data predicted significant obstruction in the presence of normal electrocardiographic, vectorcardiographic and vector lead tracings. Echocardiography offers a noninvasive method for estimating the severity of aortic stenosis, in the absence of myocardial failure; it appears to be more sensitive than other currently employed techniques.
