Use of ipsilateral greater saphenous vein as a valved transplant in management of post-thrombotic deep venous insufficiency: long-term results.

Incompetence of the deep venous valve is a common feature of post-thrombotic deep venous insufficiency. Various surgical techniques have been proposed to treat reflux. In this study we describe long-term results of a novel transposition technique using the ipsilateral greater saphenous vein. From 1984 to 1994 we used this procedure to treat 16 patients including 10 men and 6 women with a mean age of 56 years (range: 25 to 76 years). In all 16 cases the indication for surgery was incapacitating pain associated with recurring ulceration in 9 patients. From the results of using this technique we conclude that transposition using the ipsilateral greater saphenous vein is safe and effective with good mid-term results, especially for pain. For ulcers the primary success rate was 55% but this increased to 84% with proper surveillance and treatment of secondary insufficiency of the superficial venous system.

Percutaneous stenting of the internal carotid artery: the European CAST I Study. Carotid Artery Stent Trial.

PURPOSE: To report the results of a multicenter safety trial of percutaneous carotid stenting performed by vascular surgeons. METHODS: Symptomatic or asymptomatic patients > or = 65 years of age with internal carotid artery (ICA) stenoses > or = 70% and < or = 2-cm long were eligible for enrollment. The procedures were performed in an operating room with the choice of anesthesia and the percutaneous access site at the discretion of the surgeon. Only Palmaz stents were used. RESULTS: From January 1, 1996 to December 31, 1997, 99 patients (74 men, mean age 70 years, range 51 to 94) were enrolled in the study. More than half (57 of 99 patients) were asymptomatic. The direct cervical approach was used predominantly (97%). Three (3%) cases were converted to surgery for inability to access the artery or deploy the stent (technical success 97%). No perioperative death or myocardial infarction was reported. Six (6%) procedural complications included 1 reversible arterial spasm, 2 dissections, 1 cervical hematoma, and 2 residual stenoses. One neurological event reversed within 7 days (1% minor stroke rate) and 4 (4%) transient ischemic attacks resolved within 24 hours. One (1%) asymptomatic early occlusion occurred 2 days postoperatively. No neurological event was observed in the 1- to 24-month follow-up (mean 13 months). Two (2%) patients died of nonprocedurally related causes. No stent compression was seen, but 1 asymptomatic occlusion and 3 asymptomatic, non-flow-limiting restenoses (2 < 40%, 1 at 60%) were found within 1 year (3% restenosis rate on an intention-to-treat basis). Patency was 98% at 1 year. CONCLUSIONS: The results of this trial support the contention that carotid stenting of short ICA lesions can be performed with a low neurological complication rate.

Endovascular repair of iliac artery aneurysm with Endoprosystem I: a multicentric French study.

Due to their position deep in the pelvis, the classical surgical treatment of iliac artery aneurysm leads to a high morbidity and mortality rate. The transfemoral percutaneous repair of these aneurysms is now possible thanks to a new device the endoprosystem I from "Mintech". We began in 1994 a study including radiological, cardiac and vascular centers all of them skilled in endovascular procedures. 27 patients entered the study: 1 patient died, 2 attempt failed and 2 presented leakage: the immediate failure rate was then 18.5%. For the late result (min 6, Max 19, mean 12 months) we had 1 thrombosis treated by surgery, 1 restenosis treated by PTA. We did not see any polyester dilatation or reactivation of aneurysm at the scan control at one year. We conclude that the percutaneous treatment of iliac aneurysm is possible and safe but we need long term result to validate the method.

Transluminal recanalization of occluded iliac arteries: a surgical experience.

The purpose of this study was to evaluate the feasibility of transluminal techniques in an unselected group of patients and to assess long-term outcome in successful procedures. All patients in whom iliac artery recanalization was attempted were included in this study. Patients with an occluded prosthesis or recent embolism were excluded. A total of 37 patients were studied. Assessment of the success or failure of the procedure was based on the results of control arteriography. Recanalization was deemed successful in 31 patients. This study demonstrates that transluminal recanalization of occluded iliac arteries by a surgeon is indeed feasible. Primary patency was 66% at 24 months. The potential risk, however, is long-term restenosis. Thus follow-up examination every 6 months is recommended including pressure index measurements after exercise and color Doppler ultrasonography of the recanalized zone.

Recanalization of occluded superficial femoral arteries using the rotational transluminal angioplasty catheter system (ROTACS).

A total of 85 occluded superficial femoral arteries were treated using the rotational transluminal angioplasty catheter system (ROTACS). The mean length of the occlusions was 7cm; 76% were uncalcified or only slightly calcified whereas 24% were calcified or highly calcified. The mean preoperative ankle:brachial index was 0.51. Primary success was achieved in 62 of 85 cases (73%). The mean length of reperfused occlusions was 6.2 cm: 26% of these lesions were calcified. The mean ankle:brachial index was 0.91. There were 23 primary failures (27%): reperfusion was impossible in 11 cases (including one complicated by perforation) and there were eight dissections, three cases where residual stenosis exceeded 50%, and one other unspecified failure. The mean length of these occlusions was 10.5 cm; 17% were calcified. Two patients developed a distal embolus and one died 10 days after reperfusion. The probability of primary patency of a reperfused artery was 44% at 1 year. Forty-two of the 62 patients who achieved primary success remained symptom free; the mean length of the original occlusion was 4.5 cm. Fifteen patients developed a new area of stenosis whereas five others exhibited new occlusion after a mean interval of 6 months. The mean length of these reperfused arteries was 9 cm. The probability of secondary patency at 1 year was 58%. Arterial calcification did not appear to influence the feasibility of reperfusion using the catheter. The main factor determining successful reperfusion was the length of the occlusal defect (P < 0.05). Reperfusion using the ROTACS did not improve the feasibility of reperfusion by conventional transluminal angioplasty.(ABSTRACT TRUNCATED AT 250 WORDS)

Naftidrofuryl in chronic arterial disease. Results of a six month controlled multicenter study using Naftidrofuryl tablets 200 mg.

The study was carried out on patients with intermittent claudication (Fontaine's stage II). The arterial and atheromatous origin of the disease was confirmed and localized by angiography or Doppler velocimetry examination. One hundred eighty-six patients were selected initially. Their pain-free walking distance on a treadmill (at a speed of 3 km/hour and an inclination of 10%) had to be 150-300 m. During the first month all patients received 3 placebo tablets daily. At the end of this run-in period (D-30; D 0) and after checking walking distance stability (allowed variation: +/- 20% between the two measurements) the patients were included in the study. One hundred fifty-four patients were selected and 118 remained during the whole study. The study was designed as a double-blind, using two parallel randomly selected groups. Sixty-four patients received for six months Naftidrofuryl (3 X 200 mg tablets daily with meals); 54 patients received placebo under the same conditions. During this period, clinical and paraclinical examinations were carried out every quarter (D 90 and D 180). After checking the initial homogeneity of the Naftidrofuryl and placebo-groups, the comparison between groups indicates a significant improvement in Naftidrofuryl group after 3 and 6 months of treatment. At the end of the study the observed differences in walking distance with Naftidrofuryl are approximately twice the difference in the reference group (D 90: p less than 0.05; D 180: p less than 0.02). The results of this study indicate that Naftidrofuryl is an efficient pharmacological tool for treatment of patients with chronic arterial disease (Fontaine's stage II).

[Digestive endometriosis. Current concepts].

Endometriosis involving the digestive tract accounts for 1% of all cases of the disease. There is a marked predominance in the recto-sigmoid and terminal ileal loops. Symptomatology is dominated by disturbances in intestinal transit, sub-occlusion or acute obstruction, pain worsening at the time of menstruation and by a haemorrhagic rectal discharge again accompanying menstruation. Apart from classical aetiopathogenic theories such as grafting onto the digestive tract by tubal, lymph vessel or venous propagation, it would appear that prostaglandins and in particular a change in the (formula; see text) ratio may play a large role. Operative resection of localised stenosis combined with oophorectomy, if the latter is possible in view of the patient's age, or prolonged medical treatment with progestational agents or even better Danazol results in cure and avoids recurrences.

[Should one operate on all asymptomatic carotid lesions?].

Two subgroups in Natali and Thevenet's stage 0 class of asymptomatic diseases are defined. True asymptomatic affections occur in patients with neurologically asymptomatic carotid lesions. The natural history of these diseases when compared with results after surgery is in favor of preventive operative therapy. False asymptomatic affections are seen in patients who, after previous operations for symptomatic carotid lesions, present a lesion on the controlateral carotid which until then had been neurologically silent. The natural history of this group shows that immediate definitive cerebral accidents are rare and that life expectancy is low. In contrast, the course after repeat surgery, the present data being the first to be published, appears to be rather unfavorable. Careful selection of patients in this subgroup is therefore necessary when considering surgical treatment.

[Current problems posed by arterial injuries in hospital practice].

The authors analyse a series of 100 arterial lesions in respect to the localization, the time elapsed between the accident and reconstructive surgery, and the number of associated lesions (two or more). The results confirm the prognostic importance of the factor time: 83% of the good results are obtained in the first twelve hours, and only 67.5% after twelve hours. The results seen with popliteal and tibial lesions show a steady improvement from a 50% amputation rate twenty years ago to a 21.6% rate at the present time. The presence of associated lesions is equally important in the outcome: isolated arterial lesions (or accompanied by no more than two other anomalies) are successfully treated in 91% of the patients, opposed to 50% when loco-regional lesions are found (bone, skin, veins, nerves, muscles). The optional treatment of these complex traumatisms should be by means of a multidisciplinary approach.
