Purpose: To evaluate short- and long-term technical and clinical outcomes after kissing stent treatment of aortoiliac occlusive disease (AIOD) based on an individual participant data (IPD) meta-analysis. Materials and Methods: A search of the Scopus database identified 156 articles on KS treatment of AIOD; of these 22 met the inclusion criteria. Authors of 19 articles with contact information were approached to join an IPD consortium. Eight author groups responded and 5 provided anonymized data for merging into an IPD database. The number of included procedures was equal before and after 2005. The primary study outcome was the cumulative patency at 24 months. Secondary outcomes were patency at up to 60 months, complications, and changes in Rutherford category and ankle-brachial index. The predictive value of stent protrusion length, pre-/postdilation, stent type, and patient demographics on primary patency were examined with Cox proportional hazard modeling; outcomes are reported as the hazard ratio (HR). The Kaplan-Meier method was employed to estimate patency rates. Results: In total, 605 (40.9%) of 1480 patients presented in the literature were included in the IPD analysis. The indication for intervention was intermittent claudication in 84.2% and critical limb ischemia in 15.8%. Lesions were classified as TransAtlantic Inter-Society Consensus (TASC) A or B in 52.8% and TASC C and D in 47.2%. The overall primary patency estimate was 81% at 24 months. Primary patency significantly increased after 2005 (p=0.005). Cox regression analysis revealed only age as a significant predictor of sustained primary patency (HR 0.60, p<0.005). Any previous endovascular intervention (HR 2.52, p=0.02) was the main predictor for loss of secondary patency; history of cardiovascular disease (HR 0.27, p=0.04) was the main predictor of sustained secondary patency. Conclusion: The kissing stent technique has a good safety profile and acceptable patency rates up to 2 years, even in TASC C and D lesions, supporting an endovascular-first approach for AIOD.

BACKGROUND: Placement of self-expanding metallic esophageal stent in patients with advanced esophageal cancer offers excellent palliation of dysphagia and tracheo-esophageal fistulas. However, the safety of stent in patients undergoing radio and/or chemotherapy is controversial, in terms of the greater risk of complications in cases where these two treatments are used in conjunction. AIM: To assess the use of stent in patients with advanced cancer of the mid-thoracic esophagus, by comparing patients undergoing cytoreductive therapy with patients who have not undergone this treatment, in relation to improvement in the dysphagia, rate of complications, period of effectiveness and survival time. METHODS: Fifty seven patients were evaluated retrospectively (16 women and 41 men, with an average age 62 years) with advanced squamous cell carcinoma of the mid-thoracic esophagus who underwent placement of the Ultraflex™ self-expandable metallic coated stent, at the Gastrointestinal Endoscopy Unit of São Paulo University Medical School between October 1988 and October 2004. Out of the 57 patients, 24 patients received adjuvant cytoreductive therapy, and 33 patients were only treated with the stent placement. RESULTS: After stent placement, there was improvement in dysphagia in both groups; there were no differences in the rate of complications, such as migration, pain, fistula, obstruction and compression of the airways; the period of effectiveness was significantly higher in the group submitted to cytoreductive therapy (average 123 days compared to 63 days), as was the survival time (average of 210 days, compared with 120 days). CONCLUSIONS: Improvement in dysphagia was statistically significant in both groups, irrespective of whether the patient had undergone adjuvant cytoreductive therapy; there were no differences in the rate of complications between the two groups and both the period of effectiveness of the stent treatment and the survival time were higher in the group with adjuvant cytoreductive therapy.

In Stent Restenosis

The treatment of plaques near and involving coronary bifurcations (CB) is especially challenging, considering more plaques localized these regions and higher post-interventional in-stent restenosis (ISR) risk, mainly due to hemodynamic injury provoked on the arterial wall. Therefore optimization of stenting should begin with an understanding of how disease localized to these regions and why ISR formed associated with flow patterns. We chose four patients with bifurcation lesions, two patients with ISR and two without ISR according to the follow-up computed tomography angiography (CTA). Based on patient-specific pre-interventional and virtual stented geometries from CTA images, numerical simulation indicated that the wall shear stress (WSS) in stented segments, where the ISR occurred in one year, was lower than those without ISR, however. For bifurcation lesion, the stenting segments WSS is supposed a marker to forecast the ISR risk after stent treatment.
