RESUMEN

BACKGROUND: The colonic ischemic necrosis is one of the most serious complication in the surgical reconstruction of abdominal aorta aneurysm (AAA) due to surgical inappropriate binding of the inferior mesenteric artery (IMA). METHODS: A retrospective analyzed of a group of 118 infrarenal AAA surgically treated is presented. RESULTS: The most common cause of ischemic colitis (75% of cases) is the surgical binding of an opened IMA or its failed reimplantation. CONCLUSIONS: In this paper according to their personal experience and the literature data, the authors outline a diagnostic behaviour to select the patients needing the reimplantation of IMA; they suggest to complete the pre operative information with an instrumental evaluation during the surgical treatment.

RESUMEN

BACKGROUND: On the basis of a literature review and of personal experience, the authors analyze the main indications and the best strategy for elective surgical repair of infrarenal abdominal aortic aneurysm (AAA). METHODS: Personal experience concerning elective surgical treatment of 110 patients with infrarenal AAA, is presented. RESULTS: No operative deaths have been observed and the postoperative recovery was regular in 108 patients. Two early complications (colon ischemia) and ten late postoperative complications (5 pseudoaneurysms, 5 sexual dysfunctions) occurred. CONCLUSIONS: The main therapeutic guidelines concerning the management of AAA should follow specific indications (aneurysm dimensions and growth rates). Indications for operative repair of aneurysms obviously should be judged in relation to the presence or absence of associated risk factors or concomitant medical conditions. In most cases, aneurysm repair can be performed safely, despite associated medical risks, by careful preoperative evaluation and preparation.

RESUMEN

The adrenal gland is a frequent site for metastases from non small cell lung carcinoma (NSCLC). Surgical strategy in patients with operable NSCLC with adrenal synchronous metastases is yet unclear. On the basis of a literature survey and of a personal case report, the authors analyze the main indications and the best strategy for solitary synchronous metastases in the adrenal gland from NSCLC.

RESUMEN

During a 5-year period, from 1990 to 1994, 61 patients underwent prosthetic reconstruction of aorto-iliac district for aneurysmal (53 cases) or obstructive (8 cases) disease. There was no postoperative mortality; 3 cases of early perianastomotic thrombosis, 2 cases of left colon necrosis, 4 cases of femoral pseudoaneurysm and 5 cases of sexual disfunction were recorded. If accurately performed, the surgery of this arterial district offers very good early and late results.

RESUMEN

The authors report two cases of colorectal ischemic necrosis following surgical reconstruction of abdominal aorta. An intestinal resection according to Hartmann was performed in both cases. The value of prevention based on a careful anamnesis, on a precise angiography study of the abdominal aorta and of splanchnic circle in addition to inferior mesenteric artery reimplantation, when advisable, is underlined as the most effective therapeutic instrument against colorectal ischemic necrosis following surgical reconstruction of the abdominal aorta.

RESUMEN

Self-transfusion represents a method used for the restoration of haematic losses that, in recent years, has been employed more and more widely in the surgical ambit. The utilisation of this method has become increasingly frequent because of the high diffusion of blood transmitted diseases and of the incidence, not negligible, of complications relative to the transfusions of homologous blood. The techniques that are currently used are: self-donation with predeposit; inter-surgery recovery; hemodilution normal blood volume. The authors report their experience relative to the use of self-transfusion, as self-donation with predeposit and as inter-surgery recovery, employed in the treatment of haemorrhagic complications, from 1990 until now in the Department of I Surgical Clinic of University of Turin, in a series of 48 patients in which were performed infrarenal abdominal aortic repair. In practice this technique did not present any complications.

RESUMEN

The authors report their experience relative to 12 cases of adrenal "incidentaloma" surgically treated. All masses removed had a main diameter larger than 3 cm. In all patients an anterior median transperitoneal incision was performed. They didn't record postoperative mortality and the postoperative morbidity rate was 15%. In 6 cases a nonfunctioning cortical adenoma was diagnosed. No malignant neoplasm was detected in their series.

RESUMEN

A case of splenic abscess in a diabetic, cardiopathic and arteriopathic 49-year-old man is reported. The abscess developed on a previous splenic infarction caused by an embolus coming from an intraventricular thrombus. The angiographic procedure was the source of bacterial contamination (Staphylococcus aureus). The patient was successfully treated with splenectomy.

RESUMEN

The authors report their experience relative to 33 patients with hepatic hydatidosis surgically treated during the years 1987 through 1993. Various surgical techniques were employed: subtotal (21 cases) and total (5 cases) cystopericystectomy, partial pericystectomy (12 cases), hepatic resection (2 cases). The postoperative rate complication was 30% (4 cases of cholangitis, 4 biliary fistulas, 1 suppuration of residual cavity and 1 colonic fistula). The postoperative morbidity was higher in patients treated with partial pericystectomy. There was no postoperative mortality.

RESUMEN

The authors report a case of intrabiliary rupture of some recurrent hepatic hydatid cysts. The biliary drainage was performed endoscopically during ERCP. The results of treatment were satisfactory. The value of total cystopericystectomy and external biliary drainage on prevention of cyst-biliary fistulas is underlined.

RESUMEN

The authors report their experience relative to 8 patients who underwent IMA revascularization during infrarenal AAA repair. The Carrel patch technique was employed in all cases operated. With this procedure no ischemic intestinal complication occurred. Two cases of ischemic colitis were observed in a second group of 40 patients operated for AAA in whom the IMA wasn't reimplanted into the aortic graft. The overall incidence of acute intestinal ischemia was 4%.

RESUMEN

The authors report their experience relative to 102 patients evaluated with carotid duplex-scanner. Ultrasonographic data of atherosclerotic carotid changes have been correlated with the outcome of the tested series. In fact, echographic images of vascular changes with high thromboembolic risk (ulcerated plaque) have been associated with cerebrovascular injuries in 25% of the cases. Furthermore, the duplex-scanner showed the need for surgical treatment (TEA) in 32 patients with asymptomatic carotid stenosis. Therefore, this noninvasive diagnostic tool seems to play an essential role in the prevention of cerebrovascular ischemia.

RESUMEN

The paper reports a case of mesenteric fibromatosis with familial polyposis, an association which was diagnosed as Gardner's syndrome, and highlights the complications connected to mesenterial desmoid tumours. In addition, the importance of radical surgical therapy of these neoplasias is underlined. Lastly, it is hypothesised that full screening of patients affected by familial polyposis might show a greater incidence of association between widespread polyposis and pathological changes attributable to Gardner's syndrome.

RESUMEN

The Authors present a case of popliteal artery entrapment syndrome due to an anomalous insertion of medial head of the gastrocnemius muscle. The patient, a 47-year-old man, with calf claudication, was examined with Doppler velocimetry and angiography. He was successfully treated by surgical intervention. A medial approach to the popliteal artery was utilized and the section of anomalous head of gastrocnemius muscle and popliteal thromboendarterectomy were performed. The postoperative course was uncomplicated.
