[Venous bypass for treatment of chronic obstructive venous insufficiency of lower limbs].

About 1 to 5 percent of patients affected by chronic obstructive venous disease of the lower extremity, are eligible to surgical treatment, by veno-venous bypass, for the relief of unerely invalidating symptoms. Indications to operation include a class II to III chronic venous insufficiency of the deep venous system, failure of medical treatment continued for at least 12 months, good patency of outflow axis, a significant gradient of pressure between discared and outflow axis, a good quality saphenous vein to be utilized for bypass. The case of an aged patient, successfully treated with a femoro-femoral venous bypass, associating an artero venous fistula, is presented and indications to the operation in the older patients, together with indication to and technical details of performing the fistula are discussed.

[Acute enterorrhagia in a young adult: emergency treatment].

A case of enterorrhagia sustained by arteriovenous malformation of the caecum in a young patient is reported. The importance of an early diagnosis to avert a serious anemia is underlined. Preminent role of colonscopy and selective visceral angiography in the diagnosis of such disease is discussed. At first a conservative urgently treatment of caecum bleeding is advised. Subsequently, when the patients is in more favourable conditions, an elective surgical operation is considered as essential.

Treatment of gunshot wounds to the colon: experience in a rural hospital during the civil war in Somalia.

BACKGROUND: In the last few decades there has been a clear tendency in civilian practice towards primary repair of gunshot wounds to the colon, resulting in a substantial decrease in the number of colostomies performed for this type of injury. METHODS: The series described here comprises 24 patients with gunshot wounds to the colon treated at the hospital of Jowar in the Middle Shebelle region of Somalia between 1999 and 2001. All injuries were caused by war arms firing high-velocity projectiles. RESULTS: In 18 patients surgery consisted of resection and immediate anastomosis, while in the remaining six patients colostomies were performed including five loop colostomies and one terminal colostomy. The sepsis-related mortality was 25% (6/24). CONCLUSION: Our experience had a peculiar setting, namely that of a civil war in a developing country. In this kind of "difficult" situation there probably exists no ideal procedure and the decisions taken at the operating table are influenced by various factors that are often related to subjective assessment.

[Revascularization of the carotid and vertebral arteries in the elderly].

From January 1994 to July 2004, 323 patients underwent 348 revascularization of carotid bifurcation for atherosclerotic stenoses. Eighty eight patients (group A) were 75 year-old or older, whereas 235 (group B) were younger than 75 years. Postoperative mortality/neurologic morbidity rate was 1% in group A, and 1.4% in group B. At 5 years, patency and freedom from symptoms/stroke were, respectively, 91% and 92% in group A, and 89% and 91% in group B. None of these differences was statistically significant. In the same time period, 26 internal carotid arteries were revascularized in 24 patients, 75 or more aged, for a symptomatic kinking. Postoperative mortality/morbidity rate was absent, whereas, at 5 years, patency and freedom from symptoms/stroke were, respectively, 88% and 92%. Twelve vertebral arteries were revascularized in 12 patients, 75 or more aged, for invalidating symptoms of vertebrobasilar insufficiency. Postoperative mortality/neurologic morbidity rate was absent. In one case postoperative recurrence of symptoms occurred, despite a patent revascularization. Patency and freedom from symptoms/stroke were 84% and 75%, at 5 years. Revascularization of carotid and vertebral arteries in the elderly can be accomplished with good results, superposable to those of standard revascularization of carotid bifurcation in a younger patients' population.

The treatment of chronic intestinal ischemia.

BACKGROUND AND AIMS: Due to the rarity of the condition, large and prospective series defining the optimal method of digestive arteries revascularization, for the treatment of chronic intestinal ischemia, are lacking. The aim of this consecutive sample clinical study was to test the hypothesis that flexible application of different revascularization methods, according to individual cases, will yield the best results in the management of chronic intestinal ischemia. PATIENTS AND METHODS: Eleven patients, of a mean age of 57 years, underwent revascularization of 11 digestive arteries for symptomatic chronic mesenteric occlusive disease. Eleven superior mesenteric arteries and one celiac axis were revascularized. The revascularization techniques included retrograde bypass grafting in 7 cases, antegrade bypass grafting in 2, percutaneous arterial angioplasty in 1, and arterial reimplantation in one case. The donor axis for either reimplantation or bypass grafting was the infrarenal aorta in 4 cases, an infrarenal Dacron graft in 4, and the celiac aorta in one case. Grafting materials included 5 polytetrafluoroethylene (PTFE) and 3 Dacron grafts. Concomitant procedures included 3 aorto-ilio-femoral grafts and one renal artery revascularization. Mean follow-up length was 31 months. RESULTS: There was no operative mortality. Cumulative survival rate was 88.9% at 36 months (SE 12.1%). Primary patency rate was 90% at 36 months (SE 11.6%). The symptom free rate was 90% at 36 months (SE 11.6%). CONCLUSIONS: Direct reimplantation, antegrade and retrograde bypass grafting, all allow good mid-term results: the choice of the optimal method depends on the anatomic and general patients status. Associated infrarenal and renal arterial lesions can be safely treated in the same time of digestive revascularization. Angioplasty alone yields poor results and should be limited to patients at poor risk for surgery.

The surgical treatment of ilio-femoral venous obstruction.

METHODS: A series of 9 patients of a mean age of 48 years, operated on for compression of the ilio-femoral venous axis is reported. The cause of obstruction was external compression in 3 cases, a retroperitoneal sarcoma in 1 case, and an infrarenal aortic aneurysm in 2. Two patients presented with a Cockett's syndrome, 3 with a chronic ilio-femoral thrombosis, and one with a post-traumatic segmentary stenosis. Treatment consisted in a resection/Dacron grafting of 2 infrarenal aortic aneurysms, one femoro-caval bypass graft, 2 transpositions of the right common iliac artery in the left hypogastric artery for Cockett's syndrome, 3 Palma's operations for chronic thrombosis, and one internal jugular vein interposition for segmentary stenosis. RESULTS: There were no postoperative deaths and no early thromboses of venous reconstructions performed. All the patients were relieved of symptoms during the follow-up period, whose mean length was 38 months. CONCLUSION: The cause of venous obstruction and the presence of symptoms which are resistant to medical treatment are the main indications to ilio-femoral venous revascularization. The choice of the optimal treatment in each single case yields satisfactory results.

Photodynamic therapy in general surgery.

Authors' experience in detecting neoplasms by a computerized telethermographic system in animal models is reported. The new technique seems to have a great potential as a photo-diagnostic method particularly when followed by the surgical treatment or the photodynamic therapy (PDT) of the neoplastic lesions. Literature reports on the PDT of tumors are reviewed.

[The use of human fibrin glue in fistulous pathology of the lung].

Currently, bronchopleural fistulas present a decreasing complication rate in thoracic surgery, especially since surgical management of tubercular infections is no longer needed. The introduction of non-reacting suture materials and the technological advances have also lowered the incidence of such complication. Although fistulas tend to be chronic, their treatment is possible. Today, in fact, the use of human fibrin glue gives positive results which depend on the extent of the fistula as well as the adherence of the glue to the bronchial wall. The authors report their experience in two cases treated with human fibrin glue.
