RESUMEN

OBJECTIVE: The aim was to assess 18 month outcomes of the paclitaxel eluting balloon (PEB) in patients with femoropopliteal (FP) in-stent restenosis (ISR). METHODS: In a national prospective and multicentre cohort study, symptomatic patients with femoropopliteal in-stent restenosis were included from January 2012 to June 2013. Patients were treated by paclitaxel eluting balloon angioplasty (In Pact Admiral, Medtronic, Santa Rosa, CA, USA). Clinical and duplex scan follow-up evaluations were performed at 1, 3, 6, 9, 12, and 18 months. The primary endpoint was freedom from target lesion revascularisation (TLR) at 12 months. Secondary endpoints were major adverse cardiovascular events (MACE), Target extremity revascularisation (TER), primary and secondary sustained clinical improvement, recurrent restenosis rate, primary and secondary patency, quality of life assessed by EQ-5D questionnaire, technical success, clinical success, and length of stay RESULTS: A total of 53 patients were enrolled. After a blinded review, 10 patients were defined as protocol violation because restenosis occurred more than 2 years after stent implantation. Procedures were performed in 55 limbs, 48 (87%) for claudication and 7 (13%) for critical limb ischaemia. The mean diameter and length of PEB were 6 ± 0.57 mm and 86 mm ± 32 mm, follow-up was 17 months (range 1-19). At 1 year, the survival rate was 96 ± 2.7% and freedom from TLR and TER were 90.2 ± 4.2% and 85 ± 5%, respectively. Sustained primary and secondary clinical improvements were 78.6 ± 5.7% and 92.0 ± 3.8%, respectively. At 1 year, the primary patency rate was 83.7 ± 5.0%. Prior to the procedure, the mean EQ-5D score was 66 ± 14 and 74 ± 16 at 1 year (p = .10). Two patients died during follow-up; one patient died 33 days after the procedure because of limb ischaemia. CONCLUSION: PEB for the treatment of FP ISR is associated with a low rate of re-interventions and restenosis. Clinical improvement is maintained at 18 months.

RESUMEN

STUDY AIM: Radiofrequency (RF) ablation of malignant hepatic tumors is an interesting and recent technique which offers new treatment possibilities. In this study, the preliminary findings have been reported on 25 patients with hepatic tumors who received RF treatment between January 1998 and February 2000. PATIENTS AND METHODS: Twenty-five patients (11 cases of hepatocellular carcinoma, HCC; and 14 cases of liver metastases, LM) underwent RF treatment. Thirty tumors (range: 10 to 54 mm in diameter) out of a total of 63 were destroyed by RF: 13 HCC (average diameter: 32 mm) and 17 LM (average diameter: 26 mm). Treatment consisted of six percutaneous and 19 surgical RF procedures. In the surgical group, there were 11 cases of hepatectomy: right hepatectomy in five patients with segment IV enlargement in one case, and sub-segmentectomy in six other patients. In all cases, hepatic tomodensitometry was performed at one month post-treatment and then every three months. RESULTS: Postoperative portal thrombosis occurred in two patients, one of whom died. Other postoperative complications were observed in five patients. During the mean follow-up period of 14 months (range: 2 to 28 months), two patients died (carcinosis, ascitic decompensation), two and four months respectively after RF treatment. In situ recurrence occurred in four HCC and two LM patients. Three HCC and four LM patients developed new hepatic or extra-hepatic lesions. CONCLUSION: RF is a particularly interesting technique for the treatment of bilobar or unresectable metastases. It appears to be equally as efficient as other local treatments for small-sized HCC. However, technical improvements remain necessary to increase the destructive field covered by RF. A more important follow-up is needed so that the long-term efficacy and specific role of this new therapy can be accurately assessed.

RESUMEN

STUDY OBJECTIVE: The objective of this retrospective study was to report the long-term results of distal revascularization at the ankle in patients with critical ischemia. PATIENTS AND METHODS: From January 1989 to November 1999, 50 inframalleolar bypasses were performed in 49 patients (35 males and 14 females with a mean age of 75 years [range: 51 to 95 years]). Twenty-five patients (50%) were diabetics. All patients presented with critical ischemia of the lower limb. Distal anastomosis was performed at the retromalleolar posterior tibial artery in 28 cases (56%), pedal artery in 20 cases (40%) and distal fibular artery in two cases (4%). Bypasses were performed using a greater saphenous vein (n = 38), a cryopreserved arterial allograft (n = 9), or a PTFE graft (n = 2). A composite graft with greater saphenous vein and arterial allograft was performed in two cases. RESULTS: There were two early postoperative deaths. One patient presented a blow-out of the distal anastomosis that required bypass ligation and subsequent leg amputation. Early thrombosis of the graft occurred in four cases, leading to major amputation in three cases. No patients were lost to follow-up and mean follow-up was 26.7 months (range: 1 to 86 months). Graft thrombosis occurred in 15 patients and led to amputation in 6 cases. Bypass graft patency rate was 72% and 61% at 1 year and 3 years, respectively, yielding a 80% limb salvage rate at 3 years. The 3-year actuarial survival rate was 53%. CONCLUSION: Inframalleolar bypasses are a valuable tool in patients with critical ischemia. The lower limb salvage rate is satisfactory in this elderly population. Based on this experience, angiography with good run-off and, when necessary, a surgical approach to verify patency of the arteries at the ankle should always be performed before undertaking a major amputation.

RESUMEN

The shortage of organ donors has led to progressive softening of selection criteria for organ donation. We report on hepatic transplantation in a 55-year-old woman with primary biliary cirrhosis, whose donor was a 50-year-old heart transplant recipient who became brain stem dead, due to cerebral bleeding 8 months after transplantation. An orthotopic liver transplantation was performed. The postoperative course was uneventful and the recipient was alive and had normal liver function after a 42-month follow-up. Analysis of the literature included ethical consideration, potential hepatotoxic effects of immunosuppressive drugs and modification of the graft immunogenicity. It confirms that transplanted patients should not be a priori excluded from organ donation.
