Treatment of a Patient with Abdominal Aortic Aneurysm and Hepatocellular Carcinoma.

BACKGROUND: The surgical tactics in cases of abdominal aortic aneurysms (AAA) and intra-abdominal malignancy are not uniform in the literature and are still a matter of debate. In this case report, we present a patient with coexisting AAA and primary liver cancer managed by simultaneous open AAA repair and liver resection After laparotomy and intraoperative liver ultrasonography that confirmed resectability of the tumor, aneurysm repair was performed with aorto-aortic tube grafting after interrenal cross-clamping Radiofrequency-assisted liver transection was performed to complete an anterior anatomic resection of liver segments VI and VII. The postoperative course was uneventful and the patient was discharged on a postoperative day 10. METHODS: This was prospective follow up of one patient. RESULTS: The patient is free from disease at 18-month follow-up. CONCLUSIONS: The best treatment strategy for patients with AAA and malignant disease is still not clearly defined. Strategy selection is made individually according to the risk of rupture of AAA, general condition of the patient, experience of the teams that should perform the procedure and estimated life expectancy after resection of malignant disease.

Carotid replacement with Dacron graft in 292 patients.

INTRODUCTION: In case of highly atherosclerotic carotid process, carotid graft replacement might be a potential solution for successful procedure. Many studies evaluated the results of vein and polytetrafluorethilen (PTFE) graft usage at the carotid bifurcation, while the experience on the Dacron graft due to extensive atherosclerotic process is missing. The aim of our study was to evaluate 30-day and long-term results of the Dacron graft on carotid artery used in patients with extensive atherosclerotic disease. MATERIAL AND METHODS: This retrospective study analysed early and long-term neurological outcome as well as Dacron graft patency in patients operated with carotid reconstruction. Early results were confirmed by follow-up clinical examination, whereas late results were assessed by follow-up clinical examination as well as duplex sonographic examination at least 1 year after the surgery. As for statistical methods we used descriptive analysis tests, Chi-square test, and logistic regression. RESULTS: Carotid graft replacement was performed in 292 patients, before endarterectomy in 155 (53.09%), or after already attempted unsuccessful eversion endarterectomy in 137 (46.91%). Nineteen (6.5%) patients had a stroke due to ipsilateral and contralateral ischaemia or haemorrhagic in 17 (5.8%), 1 (0.3%) and 1 (0.3%) patients, respectively. Significantly higher rate of strokes occurred when the graft reconstruction was used after the failure of endarterectomy (8.5% vs. 3.5%, p = 0.029). Stroke and death rate was 7.19%. Factors that increased risk of early stroke were the length of plaque in the internal carotid artery measured intraoperatively (p = 0.025) and the surgical tactic to perform graft reconstruction after attempted extensive endarterectomy (p = 0.029). CONCLUSION: Low number of patients with carotid stenosis has extensive atherosclerotic process longer than 4 cm that might jeopardise eversion endarterectomy. Carotid graft replacement with Dacron graft provide early results that are comparable with other conduits; however, in such patients reconstruction should be selected individually based on surgical experience and anatomical distribution of stenotic disease. Due to high risk of stroke, only symptomatic patients with such extensive atherosclerotic disease should be operated.
