The internal mammary artery is the most frequently used bypass conduit for the left anterior descending coronary artery in patients treated with bypass surgery, with excellent long-term patency rates. However, the mammary artery may also be affected by functionally significant stenoses. Most stenoses of the mammary artery are secondary to the surgical procedure at the anastomosis site, but atherosclerotic lesions may also develop. The mammary artery is often tortuous and extreme kinking of the vessel may cause flow obstruction. The treatment of such kind of stenoses is not codified. The clinical course and interventional procedure of 2 patients with previous mammary artery bypass graft and severe angina due to kinking stenosis of the graft are described. The 2 cases are characterized by the short time frame during which the stenosis became apparent, suggesting a vasoactive component in the first case that was resolved with medical treatment and an aggressive atherosclerotic progression in the second that required a percutaneous intervention. Therefore, etiology of the stenosis of the body of the mammary artery graft may differ from that of the native circulation. The role of marked bends in bypass grafts could deserve selective studies to determine whether they are associated with the development of functional stenosis. This information may be useful when performing mammary artery bypass graft surgery for avoiding extremely twisted vessel courses.

Background: At present, as a result of the introduction of tension-free techniques, the general opinion is that the treatment of inguinal hernia needs day-care surgery. Nevertheless day-care surgery requires a specific organization of the hospital and of the territorial services, after the discharge of the patient. These facilities are not always available all over the country. The aim of this paper is to present the results of the treatment of inguinal hernia performed by day-care surgery in an unspecialized hospital., Methods: From April 1999 to April 2000, 28 patients (25 M), median age 54 years (range 25-85), affected by inguinal hernia, underwent ernioplasty operation according to Trabucco technique, by only one skilled surgeon, in an unspecialized hospital. Five patients were affected by inguinal hernia of type I of Nyhus, 9 of type II, 10 of type IIIa and 4 of type IIIb. Twenty-five patients underwent spinal anaesthesia and 3 general anaesthesia due to failure of the previous one or for contraindications due to spine diseases or due to patient's request. All patients remained in the hospital the night after the operation. After discharge, patients were controlled in the outpatient ambulatory every other day for 10 days. After that, patients were required to submit to physical examination only if they were symptomatic. At present, average follow-up is of 18.1+/-6.3 months., Results: The following unspecific complications prevalently due to spinal anaesthesia were observed: 2 (7.1%) acute urinary retentions, 1 (3.6%) headache, 1 (3.6%) acute hypotension, 2 (7.1%) feverets, 1 (3.6%) vomiting, and 1 (3.6%) influenza. The specific complications were: 2 (7.1%) transient neuralgias, 2 (7.1%) ecchimosis and 1 (3.6%) infection of the wound. Average intensity of postoperative pain (VAS) was of 2.8+/-1.2. The average abstention from work was of 12.5 days. Until now, any recurrence has been observed., Conclusions: In spite of the few cases, our results are similar to those of specialized hospitals organized for day-care surgery. Anyway, in the management of these patients in unspecialized hospitals, according to our opinion one night in the hospital after the operation is required for the easiness of the patient and of the surgeon.

The authors report a case of urachal fistula diagnosed after repeated omphalitis, this disease was associated with coronal hypospadias. Diagnosis was done thanks to a fistulography; subsequently, during the operation, to evidence the fistula, this was injected with methylene blue, this expedient showed that the fistula was longer than that disclosed from fistulography. To carry out a complete extirpation of the fistula the authors were bound to make a cystotomy. The course after operation was good and the patient discharged after a few days. After 5 years the patient is in perfect health. This case allowed some anatomic, clinical and semeiotic considerations.

The whole male population with indwelling catheter of the Trento health district has been included in a survey of the quality of the home nursing services. The epidemiological and in depth analysis of the characteristics and motivation of the high degree of heterogeneity of medical prescribing behaviors and of the nursing practices suggest that an important effort of rationalization (on the basis of pre adopted protocols) is both needed and possible.

An uncommon case of traumatic rupture of chordae tendineae with tricuspid regurgitation is described. The early diagnosis, in a patient with polydistrectual injuries, was done by transesophageal echocardiography. This technique allowed accurate diagnosis of the type of lesion suggesting the opportunity to perform an echocardiogram, possibly transesophageal, in all patients with blunt thoracic trauma, even in the absence or with subtle clinical manifestations of cardiovascular involvement.

Postischemic septal rupture has always been evaluated, in respect of surgical indication, as regards the time lapse between infarct and rupture, interval between rupture and operation, extension of myocardial damage and general risk factors such as age, sex and associated pathologies. But in fact the surgeon is dealing with a two sided problem, the MI and the rupture, and thus surgical results depend upon both the residual ventricular function after MI and the consequences of volume overload on a damaged muscle. Surgical indication could not be based on a single criterion only. Extension of the MI alone is not fully predictive of operative mortality because, aside the reperfusion injury, the repair further jeopardizes viable myocardium and alters ventricular geometry; although the shunt appears unrelated to mortality it certainly interferes with operative outcome at least because of the time elapsed between rupture and repair. So far an index which could correlate the extension of myocardial damage and the entity of the shunt with each other was not available. Patients with septal rupture follow an emergency protocol and are often insufficiently investigated but every patients has a least one echo-Doppler evaluation or even a ventriculography while one or more ECGs are always available. With the presumption that the Qp/Qs is roughly indicative of the right ventricular volume overload and that ecg signs of myocardial infarct are always reliable, we have reviewed among our 24 patients with septal rupture those where a full ecg tracing and a quantitative Echo or angiographic evaluation of the shunt were available.(ABSTRACT TRUNCATED AT 250 WORDS)

The Authors report a case of peritonitis due to perforation of a single small bowel metastasis in a woman affected by right upper lobar lung carcinoma still with neck's lymphnodes and cerebellar metastasis. They underline the rarity of the finding and analyze its clinical, therapeutic, prognostic problems.

Post-infarction free-wall, papillary muscle and septal myocardium rupture yields a lowering mortality, not only due to the improved surgical technique but also to a more careful selection of surgical candidates. The value of pericardial decompression in cases of free-wall rupture is discussed. Echocardiographic evidence of blood in the pericardium after a myocardial infarction is not a direct indication for a diagnostic sampling, decompression or surgery. Pericardiocentesis is not a risk-free procedure and should be limited to patients with life-threatening acute tamponade. Clinical results of 34 patients operated upon for myocardial rupture, regardless of adopted technique or timing of surgery, confirm that the decision about a patient's operability should follow a careful evaluation of the following risk factors in this order: infarct size, age, cardiogenic shock, multiorgan failure, rupture site, cardiac failure and associated diseases.

Based on a survey of 47 cases of left colonic occlusive cancer operated on at the Emergency Surgery Department-University of Rome "La Sapienza", the authors concluded that in such condition, when the patient is not seriously ill, the Hartmann procedure is a valid alternative to the anastomosis-resection because: a) it solves intestinal obstruction in a short time with consequent improvement of general conditions; b) it allows to perform the second oncologically radical operation early with less risk of neoplastic spread. The latter procedure, therefore, is carried out under better conditions, relative to the stage of the disease and the status of the patient.
