Simultaneous nephrectomy and coronary artery bypass grafting through extended sternotomy

BACKGROUND: The advances in surgical techniques, resuscitation and anesthesiology support over the last years have allowed simultaneous thoracic and abdominal operations to be made for cancer and concomitant severe heart vessel disease relieving the patient from several diseases simultaneously and achieving long lasting remission or cure. CLINICAL CASE: A simultaneous nephrectomy and coronary artery bypass grafting procedure through extended sternotomy is reported. A 63-year-old man with severe coronary artery disease was found to have renal carcinoma. DIAGNOSIS: Postoperative pathological investigation of the tumor revealed the presence of renal cell carcinoma pT3a N0 M0, G2. Coronarography revealed advanced three-vessel coronary artery disease. TREATMENT: We successfully performed a simultaneous curative surgery for renal carcinoma and coronary artery bypass graft surgery under cardiopulmonary bypass using a novel technique of extended sternotomy. Simultaneous surgery thus appears to be a beneficial and safe approach for the treatment of coronary artery disease and resectable renal cancer in carefully selected patients

Long-term outcomes and predictors of recurrent aortic regurgitation after aortic valve-sparing and reconstructive cusp surgery: a single centre experience

Abstract Background Aortic valve sparing surgery (AVS), in combination with aortic cusp repair (ACR), still raises many questions about the increased surgical complexity and applicability for patients with pure aortic valve regurgitation (AR). The aim of this study was to investigate our long-term outcomes and predictors of recurrent AR (&gt; 2+) after AVS and reconstructive cusp surgery. Methods We reviewed data of 81 patients who underwent AVS (a reimplantation technique) with concomitant ACR for AR and or dilatation of the aortic root at our institution during the period from April 2004 to October 2016. On preoperative echocardiography, the majority of the patients, 70 (86.4%) presented with severe AR grade (&gt; 3+) and 28 (34.5%) of the patients had the bicuspid phenotype. Time to event analysis (long-term survival, freedom from reoperation, and recurrence of AR &gt; 2+) was performed with the Kaplan–Meier method. Multivariate Cox regression risk analysis was performed to identify independent predictors of recurrent AR (&gt; 2+). The mean follow-up was 5.3 ± 3.3 years and 100% complete. Results The in-hospital (30-day) mortality rate after elective surgery was 1.2%. The overall actuarial survival rates were 92.9 ± 3.1% and 90.4 ± 3.9% at five and 10 years, respectively. Actuarial freedom from recurrent AR (&gt; 2+) was 83.7 ± 4.5% within the cohort at five and 10 years. The cumulative freedom from all causes of cardiac reoperation was 94.2 ± 2.8% within the cohort at 10 years. Neither bleeding nor thromboembolic or permanent neurologic events were reported during follow-up. By multivariate analysis, independent predictors of reccurent AR (&gt; 2+) were an effective height lower than 9 mm (p= 0.02) and intraoperative residual mild AR (p= 0.0001). Conclusions AVS with ACR, combined in a systematic fashion, is a safe and reproducible option with low risk of long-term valve related events and normal life expectancy for patients with pure aortic regurgitation. The competent aortic valve and effective height, not lower than 9 mm intraoperatively, are mandatory to achieve long-lasting AV competency. </jats:sec

Surgical dilemma – spare or replace regurgitant aortic valve: Late comparative outcomes of two strategies

Background To evaluate different aortic root surgery techniques and their contemporary clinical outcomes in patients with regurgitant aortic valve and aortic root aneurysm. Methods The study consisted of 141 adult patients who underwent aortic valve reimplantation (David group = 73) or aortic valve replacement surgery (Bentall group = 68) for aortic valve regurgitation (AR) and dilatation of the aortic root at our institution within the same period (April 2004–October 2016). Kaplan–Meier method was used to estimate survival and other clinically relevant outcomes between the groups. Results The completeness of clinical follow-up was 100%, with a mean time of 8.0 ± 3.8 years. Thirty-day (in-hospital) mortality rates were equivalent between groups (1.3 and 1.5%, p = 1.0). The overall survival rates at 10 years were significantly better for the David group patients comparing to Bentall group patients (95.3 ± 2.6% vs 79.7 ± 6.8%; p = 0.04) with similar freedom from AV related reoperation (94.4 ± 2.7% vs 98.5 ± 1.5%; p = 0.2). Freedom from bleeding events at 10 years was 90.7 ± 3.6% for Bentall group patients and none were observed among David group patients ( p = 0.01). Conclusions Aortic valve and root surgery can be performed with equivalent safety and efficacy using either valve-sparing (David procedure) or valve-replacing (Bentall procedure) techniques in selected patients. Furthermore, patients after the David procedure demonstrated significantly improved survival and low risk of bleeding in comparison to the Bentall procedure with an acceptable risk of reoperation at 10 years follow-up. </jats:sec
