Early onset of deep sternal wound infection after cardiac surgery is associated with decreased survival: A propensity weighted analysis.

ABSTRACT:

Objectives

To compare outcomes after the development of early (≤30 days) versus delayed (>30 days) deep sternal wound infection (DSWI) after cardiac surgery.

Methods

Between 2005 and 2016, 64 patients were treated surgically for DSWI following cardiac surgery. Thirty-three developed early DSWI, while 31 developed late DSWI. The mean follow-up was 34.1 ± 32.3 months.

Results

Survival for the entire cohort at 1, 3, and 5 years was 93.9%, 85.1%, and 80.8%, respectively. DSWI diagnosed early and attempted medical management was strongly associated with overall mortality (hazard ratio [HR], 25.0 and 9.9; 95% confidence intervals [CIs], 1.18-52.8 and 1.28-76.5; p-value .04 and .04, respectively). Survival was 88.1%, 77.0%, 70.6% and 100%, 94.0% and 94.0% at 1, 3, and 5 years in the early and late DSWI groups, respectively (log-rank = 0.074). Those diagnosed early were more likely to have a positive wound culture (odds ratio [OR], 0.06; 95% CI, 0.01-0.69; p = .024) and diagnosed late were more likely to be female (OR, 8.75; 95% CI, 2.0-38.4; p = .004) and require an urgent DSWI procedure (OR, 9.25; 95% CI, 1.86-45.9; p = .007). Both early diagnosis of DSWI and initial attempted medial management were strongly associated with mortality (HR, 7.48; 95% CI, 1.38-40.4; p = .019 and HR, 7.76; 95% CI, 1.67-35.9; p = .009, respectively).

Conclusions

Early aggressive surgical therapy for DSWI after cardiac surgery results in excellent outcomes. Those diagnosed with DSWI early and who have failed initial medical management have increased mortality.

Project description:BackgroundThe pectoralis major muscle is a versatile flap used as an advancement or turnover flap for the treatment of deep sternal wound infection (DSWI) after median sternotomy. Advancement flaps provide suboptimal mass volume and sometimes cannot fully fill the dead space in the mediastinum. Turnover flaps can sufficiently cover the inferior sternum and fill dead space; however, the procedure requires disinsertion of the muscle from the humerus, resulting in functional loss and cosmetic deformity. In an attempt to optimize the benefits and minimize the drawbacks of both flaps, we developed a novel turnover flap method using the bilateral partial pectoralis major muscle. In this study, we introduce this new flap method and report its initial clinical results.MethodsThe bilateral pectoralis major muscle is split into upper and lower parts according to the direction of the muscle fibers. The upper part of the pectoralis major muscle on one side and the lower part of the pectoralis major muscle on the other side were selected as the turnover flaps. The parts of the pectoralis major muscle selected as turnover flaps were transected vertically at the midline of the clavicle. Our novel turnover flap method was used to treat 11 patients with DSWI following cardiac surgery.ResultsNo deaths occurred in the group. In 10 patients, the chest incision healed without complications and reoperation, while 1 patient experienced delayed healing of the skin incision. None of the patients experienced subcutaneous hematoma or oozing that required reopening and drainage. The average hospitalization time was 14±7.9 days. After 6 months of follow-up, none of the patient had experienced recurrence of DSWI. Abnormal movement of the upper limbs or deformities of the chest wall were not detected in all 11 patients.ConclusionsBilateral partial pectoralis major muscle turnover flaps are appropriate for the treatment of DSWI after cardiac surgery. This novel method does not only provide sufficient volume to fill the defect but can also preserve the function of the upper limbs and prevent cosmetic deformity of the chest wall.

Project description:BackgroundBilateral internal thoracic arteries (BITA) coronary bypass grafting may improve long-term outcomes but is associated with increased deep sternal wound infections (DSWIs). We analyzed whether BITA skeletonization impacts DSWIs and operative mortality (OM) using The Society of Thoracic Surgeons Adult Cardiac Surgery Database.MethodsPrimary, isolated, nonemergent/nonsalvage BITA patients (July 2017 to December 2018) in The Society of Thoracic Surgeons Adult Cardiac Surgery Database were divided into groups based on BITA harvesting technique: both skeletonized (ssBITA) and ≥1 nonskeletonized (Non-ssBITA). DSWI and OM observed-to-expected (O/E) ratios were compared using The Society of Thoracic Surgeons Perioperative Risk Models. ssBITA versus Non-ssBITA DSWI and OM adjusted odds ratios were calculated by multivariable logistic regression and corroborated by propensity score matching.ResultsWe analyzed 11,269 patients (42.8% ssBITA, 57.2% Non-ssBITA, 770 hospitals, 1448 surgeons). The ssBITA group had a higher incidence of comorbidities and off-pump surgery. Overall incidences of DSWIs and OM were 0.98% (O/E ratio, 5.1) and 1.72% (O/E ratio, 1.4), respectively, and were 28% (P = .129) and 23% (P = .096) lower in ssBITA. The DSWI O/E ratio was highest (5.9) in Non-ssBITA and lowest in ss-BITA (4.1). After multivariable adjustment, ssBITA was associated with a decreased risk of DSWIs (adjusted odds ratio, 0.66; 95% confidence interval, 0.44-1.00; P = .05), with no difference in OM. These results were confirmed among 3884 propensity score-matched pairs. DSWIs increased sharply with increasing number of risk factors for DSWIs regardless of harvesting technique, with a trend for higher DSWIs among Non-ssBITA for all risk categories.ConclusionsThe observed high O/E ratio indicates that BITA grafting is associated with increased risk of DSWIs. Risk-adjusted DSWI rate and a lower O/E ratio in ssBITA support the protective role of skeletonization.
