[Obstruction of the superior vena cava and right subclavian vein: a propos of 2 unusual cases].

Two uncommon cases of vein obstruction are presented. In the first case a syndrome of superior, caval vein obstruction was caused by idiopathic fibrous mediastinitis involving the vein wall, and creating a tumefaction in the lumen of the vein simulating the existence of a benign tumor (fibroma) of the wall. This tumefaction was removed by endvenectomy, and the venotomy was repaired by a pericardial patch. In the second case the obstruction of the right subclavian vein was caused by a stenosed valve without signs of inflammation nor consecutive thrombosis. Until the present day no other similar case of a stenosed valve in the right subclavian vein has been reported.

Paraprosthetic fistula after aortobifemoral prosthetic reconstruction: treatment by autogenous saphenous venous replacement. A case report.

Paraprosthetic fistula is a rare but dramatic complication of aortofemoral prosthetic reconstruction. Conventional treatment consisting of removal of the prosthesis and extra-anatomical revascularization results in a high morbidity and mortality rate. The authors present a patient with a paraprosthetic fistula, who was successfully treated by excision of the graft and "in situ" replacement by autogenous saphenous vein.

Transperitoneal versus extraperitoneal approach for routine vascular reconstruction of the abdominal aorta.

In this non-randomised retrospective study we have compared 79 cases with transperitoneal approach and 90 cases with extended postero-lateral extraperitoneal approach for elective reconstruction of the infrarenal aorta. In the extraperitoneal group more patients were diabetic (7.8% vs 1.3%, p < 0.05) or had a serum creatinine of more than 1.5 mg % (10.1% vs 2.5%, p < 0.05). The study shows that in spite of a higher proportion of risk factors, a longer preparation (61' vs 44', p < 0.001), dissection (55' vs 46', p < 0.05) and total procedure time (193' vs 173', p < 0.05), the need for more blood transfusion (2.8 U vs 2.3 U, p < 0.05) and colloid perfusion (2.1 L vs 1.8 L, p < 0.05) in the extraperitoneal group, the incidence of complications is not higher compared to the transperitoneal group (29% vs 24%, NS). On the contrary, problems of intestinal transit were found exclusively in the transperitoneal group (7.6%, p < 0.01). Therefore it seems that, as far as the peri- and postoperative period is concerned the extraperitoneal approach might be the technique of choice for the simple elective infrarenal aorta reconstructions.

The value of carotid stump pressure and EEG monitoring in predicting carotid cross-clamping intolerance.

The authors analyse their experience with carotid stump pressure (CSP) and electro-encephalogram (EEG) monitoring in relation to the incidence of peroperative stroke during internal carotid artery reconstruction. A series of 215 patients is presented, among whom six (2.8%) developed a peroperative stroke. The stroke rate in patients with a CSP below 50 mm Hg (n = 92) was 7% (2/27) without a shunt and 3% (2/62) with the use of a shunt. The respective numbers for patients with a CSP equal to or above 50 mmHg were 1.7% (2/123) and 0% (0/10). The EEG remained normal after cross clamping in 180 cases (84%): the incidence of stroke was 1.5% (2/138) without and 5% (2/42) with a shunt. A shunt was used in 33 of the 35 patients with EEG changes after cross clamping. None of them sustained a stroke in contrast to both patients where despite EEG changes no shunt was used (respective stroke rates 0% and 100%). It is concluded that regarding cerebral function, EEG monitoring provides more accurate information than CSP.

The venous thrombectomy: obsolete or forgotten?

This report describes the surgical management of three patients with an extended ilio-femoral deep venous thrombosis. In the first patient a residual occlusion of the common iliac vein was treated conservatively and this patient developed severe chronic venous insufficiency. In the second patient a residual (sub)occlusion of the common iliac vein was treated with a stent and this patient remained asymptomatic with two years follow-up. In the third patient no residual or underlying anatomical abnormality was found with a good result at one year. Venous thrombectomy still has a place in the treatment of deep venous thrombosis and the long term results may be improved by application of endovascular techniques.

Classic versus endoscopic perforating vein surgery: a retrospective study.

PURPOSE AND METHODS: In this retrospective non-randomized study the results of the FELDER technique (n = 29) were compared to two endoscopic techniques for ligation of incompetent perforating veins: using a mediastinoscope (n = 19) and laparoscopic instruments (n = 57). The indication was a venous ulcer in nine, five and thirteen patients respectively, lipodermatosclerosis in thirteen, five and twenty-four, and simple varicose veins in the remaining patients (NS). RESULTS: The mean number of interrupted perforating veins was 4.2, 2.4 and 3.8 (p < 0.05). The mean hospital stay was 3.5, 1.9 and 1.6 days (p < 0.0001). The mean period of convalescence was 8.7, 4.1 and 3.7 weeks (NS). The number of complications was 9 (suralis lesion 4, pain/swelling 4, wound problem 1), 6 (saphenous lesion 3, pain/swelling 3) and 15 (pain/swelling 14, deep venous thrombosis 1) (NS). Ten patients were lost to follow-up (five, two and three). Respectively 19, 12 and 45 patients were satisfied with the end-result. The condition had worsened in one, two and three patients (NS). During the short follow-up period all ulcers healed and there was no recurrence. CONCLUSIONS: The endoscopic techniques produce results comparable to the FELDER procedure, with smaller scars and a tendency towards a faster recovery.
