Coronary angioplasty versus coronary bypass. Three-year follow-up of a matched series of 250 patients.

Two hundred fifty consecutive patients treated for one or two vessel coronary artery disease with either balloon angioplasty or surgical bypass were monitored for 3 years in a study designed to determine the comparative long-term effectiveness of each treatment. The 125 patients having angioplasty were matched with the 125 patients having bypass, so that both groups had a similar number of patients with single or double vessel disease. The two groups did not significantly differ in age, male:female ratio, New York Heart Association class, or risk factors. The ejection fraction was 54 +/- 11 in the angioplasty group and 49 +/- 12 mmHg in the surgical patients (p = 0.0031). Angioplasty was deemed initially successful in 88% (110/125), unsuccessful in 10% (12/125), and in 2% (3/125) the lesion could not be crossed. Emergency bypass was performed in 10% (12/125). Four of the 125 angioplasty patients (3%) died within 30 days. Coronary artery bypass grafting was successfully performed on the matched set of surgical patients with 99% (124/125) discharged well. There was one (1%, 1/125) surgical death. The average hospital stay per patient was 4.8 +/- 3.1 days for angioplasty and 12.1 +/- 4.2 days for bypass grafting (p = 0.0000). Three-year postprocedure follow-up was obtained on 96% (236) of the 245 patients discharged alive. A second angioplasty was required in 18%, and 11 angioplasty patients subsequently required surgical bypass. Overall, 19% (23/121) of the angioplasty patients ultimately required bypass. Four late deaths occurred in the angioplasty group, which brought the early and late mortality rates to 7% (8/121). There were two late surgical deaths, which brought the combined surgical mortality to 2.5% (3/120), p = 0.1263. Patient evaluation reveals that 63% (76/121) of the angioplasty group are alive and in New York Heart Association class I or II 3 years after one or two angioplasty procedures. This figure compares with 92% (110/120) of surgical patients alive and in the same two New York Heart Association classes (p = 0.0000).

Lateral condyle fractures in children: evaluation of classification and treatment.

OBJECTIVE: To compare intra-operative findings of fractures of the lateral condyle of the humerus in children with existing pre-operative radiographic classification. DESIGN: Prospective, consecutive. SETTING: Large urban hospital. PATIENTS: 25 consecutive displaced lateral condyle (humerus fractures) in 25 children diagnosed on biplanar radiographs. INTERVENTION: Open reduction and internal fixation through a lateral approach to the elbow. MAIN OUTCOME MEASUREMENTS: Anatomic variations of the lateral condyle of the distal humerus based upon intra-operative observations; comparison of findings with pre-operative radiographic classification. RESULTS: Three anatomic types were identified: 1) nine fractures exited on the medial side of the capitellum in the capitello-trochlear groove (36%), 2) eleven fractures exited beyond the capitello-trochlear groove through the trochlear epiphysis (44%), and 3) five fractures extended across the physis medially (20%). No fracture appeared to transverse the ossified portion of the capitellum (Milch Type I). The Milch anatomic classification was found to be inaccurate in 52% of the fractures. CONCLUSION: Intraoperative findings did not correlate with the presumed preoperative radiographic diagnosis in the majority of cases. A heightened awareness of the limitations of this traditional classification system is required for operative decision.

Femoral varus derotational osteotomy in cerebral palsy.

The records concerning 64 hips in 36 cerebral palsy patients treated with varus derotational osteotomy (VDO) alone (2 hips), VDO with muscle releases (adductors, iliopsoas, hamstrings; 46 hips), and VDO, soft-tissue release, and innominate bone osteotomy (16 hips) were reviewed. There were 23 quadriplegic and 13 diplegic patients. Average age at surgery was 7 years. Average follow-up period was 3.8 years. All hips that had VDO, soft-tissue release, and innominate osteotomy were stable at follow-up. Nine hips of the 44 treated with VDO and muscle release alone dislocated, and required second osteotomies.
