The vascular geometry of human arterial bifurcations.

We used angiography to evaluate the branching characteristics of 69 morphologically normal human arterial bifurcations. Each angiographic picture was enlarged photographically and traced on paper. The diameter of the parent vessel (d0), the diameters of the two daughter vessels (d1 and d2-d1 denote the larger vessel), and the angles at which the two branches arise from the parent vessel (teta 1 and teta 2) were measured on each bifurcation. Because theoretically there are optimal values for angles and diameters that render an arterial bifurcation more efficient physiologically, the measured data were compared with predicted values. Branch diameters correlated better with predicted values than did branching angles. Twenty-six per cent of teta 1 and only 7.2% of teta 2 angles were within the optimal range; 68.2% of teta 1 and 79.7% of teta 2 were within 2% of optimal values in terms of physiologic efficiency. On the average, teta 1 angles were smaller than teta 2 angles (17.0 degrees vs. 29.5 degrees). Morphologic and hemodynamic pecularities of vessels and errors in the measuring technique must be considered in analyzing the data obtained. Moreover, branching angle measurements changed slightly with age: teta 1 became larger and teta 2 narrower. In the cardiovascular system branching angles and branch diameters follow, to some degree, the principles predicted by theory. Branching angles diverging considerably from those principles may indicate the presence of vascular disease although a direct connection has not been established.

Normal small-bowel measurements by enteroclysis.

Small-bowel length, number and thickness of folds in the jejunum and ileum, diameter of the loops, and thickness of the bowel wall were measured on double-contrast small-bowel enema radiographs, obtained from 182 patients with no jejunal or ileal morphologic abnormalities. The length of the small bowel ranged from 160 to 430 cm, with an average length of 291 cm. No correlation was observed between the number of folds and the total length.

[Indications for enteroclysis. Retrospective study on 365 patients].

Small-bowel enema was performed in 536 patients referred for suspected malabsorption, enteritis, abdominal pain or obstruction. Lesions were found in 54% of cases. The positivity of the investigation was particularly high in clinically well-defined cases, such as suspected obstruction (80%) and enteritis (72%). The main indications and criteria of application of the investigation are discussed.

[Use of digital subtraction angiography in the study of thoracic outlet syndrome].

Thoracic outlet syndrome (TOS) is characterized by neural and vascular symptoms of the upper extremity, caused by abnormal compression on the brachial plexus, subclavian-axillary artery and/or vein, when the patient makes some movements. Compression can occur on various anatomic levels: interscalene triangle, costoclavicular passage, pectoralis minor tendon. The authors describe the various stress position to point out the place of compression, etiology and the most common methods of study. They refer also their experience about TOS obtained using selective digital subtraction angiography (DSA) of both subclavian arteries in 6 patients. Thanks to DSA, that allows the dilution of contrast medium, it is possible to carry out all the stress maneuvers using a little amount of contrast medium.

[Role and possibility of intravenous digital substraction angiography in problems of renal transplantation].

Intravenous Digital Subtraction Angiography (IVDSA) was used to evaluate 6 renal allograft recipients and 3 potential renal donors. In 4 potential renal donors and in 2 allograft recipients, angiographic data were confirmed by surgery. IVDSA is a safe, accurate, easily performed, outpatient procedure; in our opinion DSA should became the procedure of choice to study vascular anatomy in renal transplant evaluation.

[Morphological lesions of the choledochus studied with combined percutaneous transhepatic cholangiography and hypotonic duodenography].

Twenty two patients obstructive jaundice were investigated by combined fine needle percutaneous cholangiography and hypotonic duodenography. The association of the two techniques enables prompt localization of the site of obstruction and definition of the nature of the lesion. It proves to be of particular use in the differential diagnosis of carcinoma of the head of the pancreas, carcinoma of the distal choledochus and carcinoma of the socalled choledochoduodenal junction.

Signal suppression of normal liver tissue by phase corrected inversion recovery: a screening technique.

A new pulse sequence characterized by simultaneous multislice spin echo (SE) and short inversion time (TI) with inversion recovery (STIR) acquisitions is demonstrated. For the STIR component, a repetition time of 1,000 ms and TI of 210 ms were chosen to suppress the signal from normal liver at 0.5 T and create a fast sequence suitable for screening purposes. Phase correction of the STIR with the SE's signal as a reference resulted in high contrast real IR images that were free of phase error artifact. In 13 min the entire liver could be imaged in 14 adjacent slices, each slice portrayed in an ensemble of four images: a T1-weighted SE image, IR real and modulus images, and a T1 map. Forty-one patients with liver pathology and 10 normal volunteers were examined with the sequence implemented on a commercially available 0.5 T imager (Gyroscan; Phillips). Images demonstrated high liver-lesion contrast and sensitivity to liver lesions. Lesions of less than 1 cm in diameter and lymphomatous lesions, commonly occult to magnetic resonance, were detected.

[Treatment of intermetatarsal neuromas with alcohol injection under US guide].

PURPOSE: The cause of intermetatarsal neuromas is unclear; the pathogenesis is, most likely, a mechanically induced degenerative neuropathy or an entrapment of the intermetatarsal nerve under the transverse intermetatarsal ligament. Treatment of intermetatarsal neuromas includes very simple methods, such as changing shoe styles, or more complex conservative treatments such as orthotic devices and steroid injections until surgical therapy. This study aimed to evaluate the neuroma's intralesional treatment with alcohol sclerosing injection as a viable alternative to steroid injections or surgery in persisting symptoms. MATERIAL AND METHODS: 23 patients with clinical symptoms of intermetatarsal neuroma and who had not undergone other treatments were treated with 30% alcohol applied under US guide. Each patient received from 3 to 7 applications at 7 to 10 day intervals. RESULTS: We performed 3 applications in 17 patients, 5 in 5 patients and 7 in 1 patient for a total of 83 applications with a technical success of 100%. A complete resolution of all symptoms was achieved in 91% of the patients. CONCLUSION: Alcohol sclerosing intralesional treatment under US guide is a viable alternative to conservative or surgery treatments in patients with intermetatarsal neuromas.

Sonographic evaluation of physiologic bolus volume in oral swallowing.

Twenty-two nondysphagic normal subjects were sonographically studied to define the average volume of a physiologic fluid bolus. Several varying volumes (5, 10, 15, and 20 ml) of water were given to assess the average size of the swallowed bolus. At the onset of oral deglutition, when placed between the dorsum of the tongue and the groove of the hard palate, the bolus has an ellipsoidal shape, thus permitting sagittal, axial, and coronal measurements. Our results indicate that swallowed bolus volume rises proportionally to water bolus given up to 15 ml and that the average size of a physiologic fluid bolus is 7 ml.

Computed tomography detection of gastrointestinal neoplasms.

Gastrointestinal (GI) tract neoplasms can be detected, evaluated and staged by computed tomography (CT), especially from high-resolution examinations, but routine CT scanning may occasionally discover GI neoplasms in patients with non-specific symptoms. We therefore evaluated the sensitivity and main signs of CT examinations resulting from routine sessions. In 46 out of 1560 patients who underwent abdominal CT, it was possible to obtain a diagnosis of primitive gastric or colo-rectal tumour by means of barium X-ray and/or endoscopy. The sensitivity rate of CT obtained from the present study was 86% in gastric tumours and 87% in colonic tumours. In gastric lymphoma, infiltrating carcinoma of stomach and rectal carcinoma, the sensitivity rate was 100%. The CT diagnosis of GI neoplasms was based on diffuse or local thickening of the gut on a solid dishomogenous mass showing contrast enhancement. The prevalence of various patterns depends on site of origin and on macroscopic features of the neoplasia. In conclusion the results suggest that abdominal CT, even if performed with a method not specifically devoted to GI tract, has high sensitivity rates and then a high probability of detecting GI neoplasms when unsuspected at time of the examination. In our series 11% of GI neoplasms were initially diagnosed by routine CT examination.

[Echography of the oral phase of deglutition].

Neither cineradiography nor videorecording are satisfactory techniques for the dynamic study of the oral phase of deglutition. Therefore, oral swallowing was studied by means of real-time sonography (US) in 20 asymptomatic patients. Both anatomy and motility of the muscles of the mouth and tongue were clearly demonstrated. Real-time US proved thus to allow an accurate and dynamic visualization of the oral phase of deglutition.

[The extent of Crohn's disease. Radiological measurements. Correlation with surgical findings].

Twenty-three patients with small intestinal Crohn's disease were studied by barium-methylcellulose infusion. All patients underwent surgery within 1-24 months (average 7 months). The extent of the lesions and the small bowel length were radiologically evaluated by means of a map measurer. The same measurements were performed at surgery. Radiological and surgical data concerning the extent of enteritis were statistically correlated (r = 0.7). The correlation between radiological and surgical measurements of total small bowel length was not significant.

[Impingement syndrome of the shoulder. Clinical data and radiologic findings].

Subcoracoid impingement syndrome pain is elicited by some positions of the upper limbs, i.e., adduction and inward rotation, whenever coracohumeral space reduces. Although acquired or congenital malformations of the humeral head and/or coracoid apophysis are the most common causes of painful syndromes, repeated flections and inward rotations of the upper limbs, typical of some sports, such as swimming and tennis, and of some sports, such as swimming and tennis, and of some kinds of work, are predisposing factors. The subcoracoid impingement syndrome exhibits on pathogenomonic signs at clinics and the specificity of diagnostic methods is low, which calls for reliable radiologic assessment of this condition. Fifteen patients with subcoracoid impingement syndrome underwent X-ray, US, CT and MR studies. Plain radiography detected no specific signs of this syndrome, but yielded useful information regarding other painful syndromes of the shoulder, such as anatomical variants of the acromion and degenerative changes. US yield was poor because of the acoustic window of the coracoid apophysis, but supraspinatus tendon changes were demonstrated in 2 cases. CT and MRI proved to be the most reliable and accurate diagnostic methods, the former thanks to its sensitivity to even slight bone changes and to its capabilities in measuring coracohumeral distance and acquiring dynamic scans and the latter because it detects tendon, bursa and rotator cuff changes. To conclude, in our opinion, when the subcoracoid impingement syndrome is clinically suspected, plain X-ray films should be performed first and followed by MR scans.
