The dacron aorta.

Total aorta replacement is a major and increasingly successful surgical procedure. The paper describes a patient whose progressive aneursymatic disease spread from the ascending segment to the bifurcation over a three-years period during which time after three separate operations, the aorta was totally replaced. The paper describes the diagnostic and surgical procedures deployed and shows the results of angiographic and CT scans. Credit for the success of the replacement is also given to the highly skilled anaesthetists and nurses involved.

Surgical treatment of carotid kinking.

The authors take in exam 34 anatomical variation in the extracranial internal carotid artery (compared with more than 450 operated carotid artery), 15 of which involved kinking in patients with overt neurological symptoms, underwent corrective surgical treatment, and test the most useful and appropriate techniques in any case.

[The superior vena cava occlusion syndrome. A case of neoplastic thrombosis due to hepatocarcinoma and cirrhosis].

The authors report their experience with 11 patients, surgically treated since 1990, affected with superior vena cava syndrome. A peculiar case of neoplastic thrombosis in hepatocarcinoma is stressed. In fact a similar case hadn't been reported in the last ten-year literature, although hepatocarcinoma may spread in different organs. A subject review and a discussion are presented.

[Surgery of the descending thoracic and thoraco-abdominal arteries. Report of 105 cases].

The Authors show their casistic of about 105 cases of thoracic descending and thoraco-abdominal aorta pathologies between 1.1.1993 and 30.12.1995. After a short introduction about the improvements in anesthesia and reanimation of these pathologies as well as the good reliability of diagnostic and currently available instruments, mortality and mobility parameters are taken into account, the last one referring to paraplegia and ARF. The casistic is evaluated splitting the cases into 2 groups, urgent surgery and election surgery, and differentiating the aneurysm type from the dissection type. Besides, the mortality and mobility are reported for any pathology, with a discussion of the parameters which drove the choice of the most suitable methodology to be adopted (ECC femoro-subclavian shunt, simple clamping). The results achieved show a mortality of 40% in urgency, between 5 and 15% in election, with a rate of paraplegia around 8-10% and a ARF between 5 and 15%. These data match the literature statistics and support the quality of the adopted methodologies.

[Spinal cord protection in surgery of the thoracic, descending, and thoraco-abdominal aorta. Comparison of methods].

The authors compare the strategus needed for the elimination of paraplegia and for protection of abdominal organs after replacement of descending thoracic or thoraco-abdominal aorta. They analyse single technique considering the advantages and the controindications; furthermore they compare these properties and those of possible variants in the light of the presentation; type of disease and general conditions of the patient. These considerations are in agreement with later literature as well as the attitude of the surgeon.

[Pseudoaneurysms after carotid endarterectomy].

Pseudoaneurysms after TEA of the internal carotid artery are one of the rarest and most severe complications of this form of surgery. Their etiology appears to depend on 3 causes: a suturing defect due to technical errors made by the surgeon or to the incorrect choice of threads; an infections, and lastly the arterial wall weakened by TEA. The patch increases the risk of false aneurysm approximately four fold. We therefore agree with other authors that, in spite of the undoubted value of the patch in the prevention of restenosis, it must only be used in the presence of an internal carotid of small diameter (less than 4 mm). Contrary to what is reported in the literature we performed both these operations under loco-regional anesthesia and a detailed knowledge of this method allows is to be performed on the carotid axis. Only through a careful follow-up of all the carotids operated can the small dilations which often do not require surgical treatmente identified. The two cases reported here were treated by the removal of the pseudoaneurysms and its replacement with a prosthesis in one case and with the vena saphena in the other. Both were monitored with clinical examination and echo-Doppler and no recidivation has been reported to date.

[Invasion of the chest wall in primary lung neoplasms].

The authors analyse a series of 5 patients who underwent pulmonary and parietal resection between 1990 and 1993 due to non.microcytoma bronchogenic carcinoma with invasion of the thoracic wall. The patients comprised four men and one woman aged between 45 and 69 years old. Thoracic pain was present in two patients. Pulmonary resection with extrapleural stripping was performed in two patients whereas a block resection from one to five ribs and the corresponding intercostal spaces was performed in the other three patients. The authors' approach is not to perform these operations according to rigid protocols but to adapt them according to the local status of tumour invasion. Therefore to resort to extrapleural resection when there is a free cleavage plane between parietal pleura and rib wall; resection in block of the wall where the carcinoma has infiltrated the endothoracic fascia or deeper. The authors do not report any major complications and record a postoperative mortality rate of 0%. In two cases the thoracic wall was reconstructed using a sheet of Gore-Tex which did not provoke rejection phenomena. Radiotherapy was carried out in cases with positive lymph nodes. The series presented here is too recent to provide significant data regarding survival. However, the only factor seen to influence prognosis in the five patients was the presence or otherwise of lymph node metastasis, irrespective of the histological type and operation performed. The five year survival rate of T3N0M0 patients is in fact similar to that of T2N0M0 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hepatic resection. A contribution and its analysis].

The authors outline their experience in the field of resective hepatic surgery, both with regard to benign and malignant pathologies, and analyse the results in relation to indications and techniques, but also focusing attention on the assessment of postoperative functional alterations, in order to evaluate the hepatic reserve and the organ's response to demolitive surgery. All operations were carried put in the First Division of Surgery at the Ospedale Civile, Asti, from January 1989 to September 1992. In all cases, even in major hepatectomies, a "trans-parenchymal" technique was adopted. Before surgery tests were carried out in relation to the topography of disease, its nature, associated pathologies and the functional hepatic reserve. Operative mortality was zero and morbidity was negligible, probably because rigorous selection criteria and indications for surgery were adopted. Morbidity was even restricted in the two patients suffering from HCC on cirrhosis (?) and this may probably be attributed to the limitation of resection to solely oncological purposes and their classification as Child-Pugh's stage A. The results regarding the liver response to demolitive surgery appear to be indicative and revealed a highly significant and discriminating difference between elective and emergency surgery.

[Major and minor complications in carotid surgery].

The Authors report their experience of major and minor complications in carotid surgery. They analyse the causes and emphasize that a thorough preoperative study and a quick surgical technique are very important in reducing the rate of complications in this essentially preventive form of surgery.

[Early gastric cancer. A follow-up of 20 cases].

The paper describes 20 cases of early gastric cancer diagnosed by endoscopy and multiple biopsies, combined with x-ray tests using a double contrast medium, with the aim of reducing the number of false negatives. Surgery was modified according to the site and macroscopic characteristics of the neoplastic lesion (type 1, 2a, 2b: total gastrectomy + extended lymphadenectomy; type 2c and 3: gastric resection, except for different indications according to the site). In line with data reported by other Authors, the five-year survival rate was 90%.

[Treatment protocol for duodenal ulcers. Outlines of indications for surgery].

105 duodenal ulcer patients were examined over a two-year period. Apart from anamnesis, endoscopy and radiology, a personal treatment protocol was used to assess the indications for medical or surgical treatment. Endoscopy undeniably plays a central role in identifying the characteristics of the ulcer and its complications and will indicate medical treatment for the majority of duodenal ulcers though it also serves to confirm or modify the indication for surgery.
