ABSTRACT

PURPOSE: We present our experiences of intra-arterial tirofiban injection through a deployed Solitaire stent as a rescue therapy after failed mechanical thrombectomy in patients with acute ischemic stroke. MATERIALS AND METHODS: Data on 18 patients treated with adjunctive tirofiban injection through a temporarily deployed Solitaire stent after failed mechanical thrombectomy were retrospectively reviewed. Solitaire stent was used as a primary thrombectomy device in 16 of 18 patients. Two patients received manual aspiration thrombectomy initially. If initial mechanical thrombectomy failed, tirofiban was injected intra-arterially through the deployed Solitaire stent and then subsequent Solitaire thrombectomy was performed. RESULTS: Fourteen patients had occlusions in the middle cerebral artery, 2 in the distal internal carotid artery, and 2 in the basilar artery. Successful recanalization was achieved in 14 patients (77.7%) after intra-arterial injection of tirofiban and subsequent Solitaire thrombectomy. Three patients without successful recanalization after rescue method received angioplasty with stenting. Overall, successful recanalization (TICI grades 2b and 3) was achieved in 17 (94.4%) of 18 patients. Periprocedural complications occurred in 5 patients: distal migration of emboli in 5 patients and vessel perforation in 1. Three patients died. Good functional outcome (mRS < or = 2) was achieved in 9 patients (50.0%) at 3 months. CONCLUSION: Rescue intra-arterial injection of tirofiban through a temporarily deployed Solitaire stent may facilitate further recanalization in cases of failed mechanical thrombectomy in patients with acute ischemic stroke.

ABSTRACT

BACKGROUND: The aim of the current study was to analyze the early and intermediate-term performance of aortic valve replacement. MATERIAL AND METHOD: Between January 1986 and January 1996, records of 61 consecutive patients who had received aortic valve replacement were reviewed. 38 were male and 23 were female patients, ranging from 10 to 71 years of age (mean: 40.5+/-11.2). RESULTS: The early death rate was 4.9% (3/61). A thorough follow-up rate of 93.1% was accomplished in these 58 patients who left the hospital (mean: 51.5+/-32.0 patient-months) under the assistance of the same operator. Three of these patients who left the hospital died. The late death rate was 5.2% (3/58). Five patients experienced anticoagulant-related hemorrhage (all were minor). Three patients had thromboembolic episodes. There was no clinical evidence of hemolysis and structural failure of valves used. Of those patients who survived, the NYHA functional class improved significantly. Linearized rate were 1.58%/patient-year and 2.0%/patient-year respectively for thromboembolism and anticoagulant-related hemorrhage. The 10 year actuarial survival rate was 83.6%. CONCLUSION: This early and intermediate-term follow-up suggests that the mechanical valve is a reliable and durable prosthesis with good hemodynamic function and low rate of prosthesis-related complication.

ABSTRACT

Video-assisted thoracoscopic surgery has recently evolved as an alternative to thoracotomy for several thoracic disorders. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indication. Using video-assisted operative thoracoscopy, we operated on 33 patients during the 2 years of our experience from June 1993 to June 1995. They were diagnosed as recurrent pneumothorax in 16, visible bulla on X-ray in 6, prolonged air leakage (longer than 7days) in 4, bilataral pneumothorax in 3, hyperhidrosis in 2, previous contralateral pneumothorax in 1, primary hemopneumothorax 1. The average duration of chest tube placement was 2.1+/-0.4 days. The mean postoperative hospital stay was 3.4+/-0.6 days. The complication was persistent air leakage (longer than 48 hours) in 3 case. Video-assisted thoracic surgery is safe, decreased pain, and shortens hospital stay.
