Mid-term outcomes for Endoscopic versus Open Vein Harvest: a case control study
<p>Abstract</p> <p>Background</p> <p>Saphenous vein remains the most common conduit for coronary artery bypass grafting with increasing uptake of minimally invasive harvesting techniques. While Endoscopic Vein Harvest (EVH) has been demonstrated to improve early morbidity compared to Open Vein Harvest (OVH), recent literature suggests that this may be at the expense of graft patency at one year and survival at three years.</p> <p>Methods</p> <p>We undertook a retrospective single-centre, single-surgeon, case-control study of EVH (n = 89) and OVH (n = 182). The primary endpoint was death with secondary endpoints including acute coronary syndrome, revascularisation or other major adverse cardiac events. Freedom from angina, wound complications and self-rated health status were also assessed. Where repeat angiography had been performed, this was reviewed.</p> <p>Results</p> <p>Both groups were well matched demographically and for peri-operative characteristics. All cause mortality was 2/89 (2%) and 11/182 (6%) in the EVH and OVH groups respectively. This was shown by Cox Log-Rank analysis to be non-significant (p = 0.65), even if adjusting for inpatient mortality (p = 0.74). There was no difference in the rates of freedom from angina (p = 1.00), re-admission (p = 0.78) or need for further anti-anginals (p = 1.00). There was a significant reduction in the incidence of leg wound infections and complications in the endoscopic group (EVH: 7%; OVH: 28%; p = 0.0008) and the skew of high patient self-rated health scores in the EVH group (61% compared to 52% in the open group) approached statistical significance (p = 0.06).</p> <p>Conclusions</p> <p>While aware of the limitations of this small retrospective study, we are heartened by the preliminary results and consider our data to be justification for continuing to provide patients the opportunity to have minimally invasive conduit harvest in our centre. More robust evidence is still required to elucidate the implications of endoscopic techniques on conduit patency and patient outcome, but until the results of a large, prospective and randomised trial are available, we believe we can confidently offer our patients the option and benefits of EVH.</p
Short term outcomes of total arterial coronary revascularization in patients above 65 years: a propensity score analysis
<p>Abstract</p> <p>Background</p> <p>Despite the advantages of bilateral mammary coronary revascularization, many surgeons are still restricting this technique to the young patients. The objective of this study is to demonstrate the safety and potential advantages of bilateral mammary coronary revascularization in patients older than 65 years.</p> <p>Methods</p> <p>Group I included 415 patients older than 65 years with exclusively bilateral mammary revascularization. Using a propensity score we selected 389 patients (group II) in whom coronary bypass operations were performed using the left internal mammary artery and the great saphenous vein.</p> <p>Results</p> <p>The incidence of postoperative stroke was higher in group II (1.5% vs. 0%, P = 0.0111). The amount of postoperative blood loss was higher in group I (908 ± 757 ml vs. 800 ± 713 ml, P = 0.0405). There were no other postoperative differences between both groups.</p> <p>Conclusion</p> <p>Bilateral internal mammary artery revascularization can be safely performed in patients older than 65 years. T-graft configuration without aortic anastomosis is particularly beneficial in this age group since it avoids aortic manipulation, which is an important risk factor for postoperative stroke.</p
Early continence in patients with localized prostate cancer. A comparison between open retropubic (RRPE) and endoscopic extraperitoneal radical prostatectomy (EERPE) ଁ
Abstract Objective: The study examined and compared continence rates in prostate cancer patients who had undergone either open retropubic prostatectomy (RRPE) or endoscopic extraperitoneal radical prostatectomy (EERPE). The core question was whether the surgical approach had an effect on the patients' continence status 3 months after surgery. Methods: We conducted a multicentric, longitudinal study in 7 German hospitals. Three hundred fifty prostate cancer patients (166 EERPE, 184 RRPE) were asked to self-assess symptoms associated with urinary incontinence (UI) 1 day before and 3 months after prostatectomy. Symptoms of UI were assessed using the EORTC QLQ-PR25 questionnaire. Urinary continence was defined according to (1) the use of no protective pad, (2) the use of up to a single protective pad in a 24-hour period, and (3) according to the patient's self-assessment. A binary regression model was employed to predict early continence status. Results: Three months after prostatectomy, 44% of patients who underwent EERPE and 40% of patients who underwent RRPE were completely continent. Patients who underwent nerve-sparing prostatectomy and patients younger than 65 years had a better chance of regaining urinary continence earlier. The surgical approach had no significant impact on the patients' continence status. Limitations of the study are a drop-out rate of 39% and sociodemographic and clinical differences between both treatment groups. Conclusions: Three months after prostatectomy, there were no significant differences between both treatment groups regarding urinary continence. The surgical approach had no significant effect on the patients' continence status. Higher age and non-nerve-sparing surgery are associated with a longer period of convalescence

The Mosaic bioprosthesis in the aortic position: seven years' results.
BACKGROUND AND AIM OF THE STUDY: The Mosaic bioprosthesis is a stented porcine aortic valve, which combines glutaraldehyde fixation with zero-pressure and root-pressure techniques and anti-mineralization treatment with amino-oleic acid for improved hemodynamics and tissue durability. The study aim was to collect intermediate-term data of the Mosaic bioprosthesis in the aortic position, the first device having been implanted in February 1994 at the authors' institution. METHODS: A total of 100 patients (49 females, 51 males) underwent aortic valve replacement with the Mosaic bioprosthesis between February 1994 and May 1999. Mean age at implant was 73.4 +/- 7.3 years. Concomitant procedures were performed in 40.0% of cases. Patients were followed up within 30 days postoperatively, after six months, and at annual intervals thereafter. Mean follow up was 3.8 years (range: 0.1-7.1 years); total follow up was 383.1 patient-years (pt-yr) and 100% complete. RESULTS: Early mortality (< or = 30 days) was 3.0%; late mortality was 4.6%/pt-yr, including a valve-related mortality of 0.6%/pt-yr. Freedom from event at seven years was 96.8 +/- 1.8% for thromboembolic events, 97.2 +/- 2.0% for thrombosed bioprosthesis, 96.6 +/- 2.6% for structural valve deterioration, 98.2 +/- 1.8% for nonstructural dysfunction, 95.9 +/- 2.0% for anti-thromboembolic hemorrhage, 98.9 +/- 1.1% for endocarditis, and 93.9 +/- 3.2% for reoperation/explant. After one year, the mean systolic pressure gradient was 15.3 +/- 6.7, 14.5 +/- 5.7, 12.7 +/- 4.1 and 12.9 +/- 4.8 mmHg for 21, 23, 25 and 27 mm valves respectively; the effective orifice area (EOA) was 1.4 +/- 0.4, 1.7 +/- 0.4, 1.8 +/- 0.4 and 2.6 +/- 0.4 cm2 for 21, 23, 25 and 27 mm valves respectively; and the EOA index was 0.8 +/- 0.3, 0.9 +/- 0.2, 0.9 +/- 0.2 and 1.3 +/- 0.1 cm2/m2 respectively. The mean left ventricular mass index was decreased significantly, from 159.7 +/- 56.8 g/m2 to 137.3 +/- 40.8 g/m2, for all valve sizes after one year. CONCLUSION: Clinical and hemodynamic performance of the Mosaic bioprosthesis was highly satisfactory during the first seven years after clinical introduction
[End of the millennium - end of the single mammary artery graft? Two internal mammary arteries - standard for the next millennium? Early clinical results and analysis of risk factors in 1487 patients with bilateral internal mammary artery bypass]
OBJECTIVE: CABG with bilateral IMA grafts (BIMA) can improve long-term results in cardiac morbidity and mortality. An enhanced incidence of bleeding and wound complications compared to patients with single IMA (SIMA) remains a matter of debate. The aim of the study was to compare the operative outcomes of patients who had undergone CABG with BIMA and SIMA in situ grafts, especially to identify patient-related risk factors, such as obesity, diabetes mellitus and age above 70 years. METHODS: Out of a total of 5144 patients operated on between January 1996 and September 1999, patients with isolated CABG (n = 3671) with BIMA or SIMA were analyzed retrospectively. In the BIMA group, the patients' (n = 1478) mean age was 64.0 years; mean EF was 62.1%. In the SIMA group (n = 2184), mean age was 65.4 years and mean EF was 60.6% (n.s.). In the BIMA group, the right IMA was led anterior of the aorta to the LAD, the left IMA to the lateral wall. In the SIMA group, the LAD was revascularized with the left IMA. Additional bypasses were performed with vein grafts. RESULTS: The 30-day mortality was 1.6% in the BIMA group, 1.7% in the SIMA group in patients under 70 years, and 4.1% (BIMA) and 4.0% (SIMA) in patients over 70 years (p = n.s.). A significantly higher blood loss was observed in the BIMA group (BIMA 979 +/- 708 ml; SIMA 790 +/- 575 ml; p 27 showed a significantly higher rethoractomy rate (SIMA 2.2%; BIMA 4.9%). A higher incidence of sternal instabilities could be observed in the BIMA group (4.2%; p 27 could be identified as a risk factor for sternal complications, but not diabetes mellitus or age over 70 years

Simultaneous carotid endarterectomy and cardiac surgery: early results of 386 patients.
The occurrence of severe carotid artery disease in more than 12% of patients requiring coronary artery bypass grafting (CABG) results in a discrepancy concerning best treatment for both diseases. We reviewed the early outcome of patients with CABG and/or valve replacement (VR) and simultaneous carotid endarterectomy (CEA).We retrospectively evaluated 386 patients after simultaneous operation between 7/1994 and 9/2010. Total 326 patients received isolated CABG, 56 CABG and/ or VR, 4 aortic surgery. Mean age was 68.3 years (range: 45 to 87). Male patients were 229. Severity of stenosis at operated side was 70 to 80% in 167, 80 to 99% in 219 patients. Total 164 patients showed bilateral carotid stenosis, 32 had contralateral occlusion. We analyzed risk factors, morbidity, incidence of neurological events, and 30-day mortality. Perioperative stroke with hemiplegia occurred in 10 patients (2.6%). Three patients experienced PRIND, seven TIA. A 30-day mortality was 5.2%. Total 8 deaths were cardiac related, 10 due to extracardial reasons, and 2 patients developed a cerebral death. Simultaneous CEA and cardiac surgery can be performed with a low risk for neurological complications and acceptable mortality. Occlusion of contralateral carotid artery could be identified as an evident predictor for increased neurological complications
