ICU transfer after elective abdominal aortic aneurysm repair can be succesfully reduced with a modified protocol. A fourteen year experience from a University Hospital.

AIM: To compare different selective criteria for Internal Care Unit (ICU) admission in two different timeframes, after abdominal aortic aneurysm (AAA) repair. A retrospective audit of acquired data was performed. METHODS: During a period of fourteen years (1994-2008), 1152 patients underwent an elective open operation for infrarenal abdominal aortic aneurysm, in our department. Six hundred and two patients (Group A) were treated in the period January 1994-January 2003, and 550 patients (Group B) between January 2003 and August 2008. Postoperatively, all patients were transferred to postanesthesia unit (PAU). After a 2 hours period of close observation, they were transferred either to the ICU or to the surgical ward, according to certain selective criteria (SC). In group A we used SC-A, for admission to an ICU, and in group B we used new, stricter, criteria (SC-B). Thirty-day mortality and morbidity, elective admissions to ICU, rate of subsequent ICU admission, from ward to ICU, and the mean hospital and ICU length of stay, were compared between the two groups. RESULTS: The use of SC-B resulted in a significant reduction of elective admissions to ICU (3.1% vs 8.5%, P<0.001). Nevertheless, the portion of patients, which were transferred with a severe postoperative complication from the ward to ICU, remained similar between the two groups (1.1% vs 0,9%, in group A and B, respectively). All other endpoints were similar in both groups. CONCLUSION: Modifying the protocol of ICU transfer, after elective abdominal aortic aneurysm repair, we can reduce the number of patients requiring ICU, without compromising patients' safety.

Surgical treatment of carotid body tumors without embolization.

AIM: Carotid body (CB) paragangliomas are rare neoplasms, usually benign. This study deals with our 10-year experience in their surgical treatment and the evaluation of its effectiveness, without preoperative embolization. METHODS: During a 10-year period, from 1995 to 2004, we studied the medical records of 11 patients with CB tumors, 8 males and 3 females, whom only one had bilateral tumors. Their age ranged from 23 to 65 years (mean 35 years) and all had a palpable neck mass. Only two of the patients were asymptomatic on admission to our department. Twelve tumors were surgically resected and no patient underwent preoperative selective embolism of his tumor. Two patients had carotid endarterectomies with venous patch angioplasty. No one of the patients underwent radiotherapy or chemotherapy. RESULTS: Perioperative mortality was zero. No stroke or any other cerebral event was observed. One patient, with a grade III tumor, had an injury of the internal carotid artery that was repaired with a vein patch. Three patients had temporal cranial nerve lesions that resolved within 3 months. No malignancy was found even in a 10-year follow-up. CONCLUSIONS: Early surgical treatment is strongly recommended in almost all patients. Their resection is a very challenging operation with good postoperative results. Preoperative embolism of the tumor does not need to be a routine procedure. To exclude malignancy, long term follow-up is necessary.

Simultaneous venous gangrene in both lower and upper limbs. A case report.

Cancer-related venous gangrene is an extremely rare paraneoplastic syndrome. Here, we present the case of a woman, who suffered from cervical cancer of the uterus and was admitted to our Clinic with venous gangrene in both the right lower and upper limbs. Neither the anticoagulant therapy, nor thrombolysis, succeeded in improving her clinical condition. Cancer is one of the most important causes of venous thromboembolism. Venous gangrene is rarely seen in these patients. Despite adequate therapy, venous gangrene in some very rare occasions may progress to affect further limbs. Mortality in these patients remains very high.

Simultaneous surgical treatment of abdominal aortic aneurysm and bilateral aneurysms of the internal iliac artery.

INTRODUCTION: The purpose of this study is to present our experience in the management of patients with abdominal aortic aneurysms (AAA) and aneurysms in both the internal iliac arteries (IIA) at the same time. METHODS: Between 2000 and 2005, a series of 13 patients with AAA and also aneurysms in both the IIA, were treated in our clinic. They were all men with a mean age of 74 years. The size of the IIA aneurysms (IIAA) ranged from 2.0 to 8.0 cm (mean, 3.4 cm). All patients underwent an aneurysmatectomy of the AAA and placement of a prosthetic bifurcated aorto-biiliac or -bifemoral bypass, by a transperitoneal approach. The management of one of the two IIAA was the aneurysmatectomy and the direct revascularization of the healthy peripheral portion of the remaining IIA with the ipsilateral leg of the aorto-biiliac bypass. The other IIAA was treated with proximal ligation of its neck and aneurysmorraphy. RESULTS: No patient died during the first 30 postoperative days. Morbidity was about 7.7% (one patient suffered from 'trash foot', which was treated successfully with conservative measures). Finally, the mean stay in hospital was 7 days and no patient clinically presented symptoms of pelvic or colonic ischaemia. CONCLUSIONS: Simultaneous treatment of AAA and bilateral IIA aneurysms is a technically difficult, but safe procedure, if it is performed meticulously. Revascularization of at least one internal iliac artery is strongly recommended in order to avoid dangerous complications, such as pelvic or colonic ischaemia.
