Prognostic values of the C-reactive protein to albumin ratio and prognostic nutritional index in carotid endarterectomy patients.

OBJECTIVES: C-reactive protein to albumin ratio (CAR) and prognostic nutritional index (PNI) are novel parameters with proven prognostic importance in the postoperative outcomes of coronary and peripheral vascular diseases. In this study, we aimed to evaluate the ability of CAR and PNI to predict major cardiac and cerebrovascular events (MACCE) during the postoperative period of Carotid artery endarterectomy (CEA). METHODS: A total of 505 carotid endarterectomy patients were retrospectively evaluated. Of 505 patients, 23 patients who died and who experienced myocardial infarction or major neurologic complication in the first 30 days after the operation were included in MACCE group (Group 1). The remaining 482 patients were included in Group 2. Receiver operating characteristics (ROC) curve analysis was used to evaluate preoperative serum albumin value, lymphocytes count, PNI, and CAR to predict the MACCE. The DeLong test was used to compare the area below the curve (AUC) with each of these parameters. RESULTS: CAR (2.48 ± 1.82 and 1.64 ± 1.37) and CRP (9.98 ± 7.42 and 6.81 ± 5.70) values are statistically higher in Group 1 than in Group 2. PNI (41.59 ± 3.11 and 43.54 ± 4.20) and albumin (40.43 ± 3.15 and 42.35 ± 4.15) values were significantly lower in Group 1 than in Group 2. The accuracy of albumin (AUC: 0.669) in the prediction of MACCE was found to be the highest among CAR (AUC: 0.631), PNI (AUC:0.667), and CRP (AUC:0.631). CONCLUSION: Preoperative nutritional and inflammatory status is significantly associated with post-operative outcomes. PNI and CAR can be used for preoperative evaluation, as CEA is recommended for patients who have low possibility of having postoperative major adverse events.

Obesity Does Not Affect Major Outcomes in Robotic Coronary Surgery.

BACKGROUND: Robotic-assisted coronary surgery is gaining attraction as an alternative to traditional open-heart procedures, offering potential benefits such as decreased mortality rates, shorter hospital stays, and reduced complications. This study aimed to investigate the outcomes of robotic-assisted coronary surgery, focusing particularly on the impact of obesity. METHODS: A total of 210 consecutive patients underwent robotic-assisted coronary surgery over an eight-year period at a single institution. Patients were categorized based on body mass index (BMI), distinguishing between obese (BMI ≥30 kg/m2) and non-obese (BMI <30 kg/m2) groups. The analysis encompassed preoperative characteristics, operative factors, and postoperative outcomes. RESULTS: Comparisons between obese and non-obese patients revealed similar preoperative comorbidities. However, the operation time was prolonged in the obese group (p = 0.03). Major cardiac and cerebrovascular events, along with overall complications, displayed no significant disparities between the groups. Notably, superficial wound infections were more prevalent among obese patients (p = 0.03). Importantly, intensive care unit and hospital stay times were comparable between the two groups. CONCLUSION: Robotic-assisted coronary surgery demonstrates its potential as a viable alternative to conventional open-heart procedures, offering benefits such as reduced mortality rates, shorter hospital stays, and minimized perioperative complications. This study's findings underscore the feasibility and safety of this approach, with outcomes comparable between obese and non-obese patients.

Impact of Indexed Effective Orifice Area on the Quality of Life of Patients after Aortic Valve Replacement.

BACKGROUND: Improving health related quality of life is an important goal of aortic valve replacement. Inadequate effective orifice area of prosthesis according to the patient's body surface area may be associated with poor outcomes. In this study, we aimed to analyze impact of indexed effective orifice area (iEOA) on patients' quality of life after aortic valve replacement. METHODS: A total of 138 patients who underwent isolated aortic valve replacement were included to the study. Quality of life assessment was performed with EuroQol Group EQ-5D-5L questionnaire. Patients were divided into three groups based on iEOA (Group 1 had an iEOA of <0.65 cm2/m2 (19 patients), Group 2 had an iEOA between 0.65-0.85 cm2/m2 (71 patients), and Group 3 had an iEOA of >0.85 cm2/m2). Mean EQ-5D-5L scores were compared among the groups statistically. RESULTS: Mean EQ-5D-5L scores were lower in Group 1 than in Groups 2 and 3 (Group 1: 0.72 ± 0.18, Group 2: 0.83 ± 0.20, and Group 3: 0.86 ± 0.9, p = 0.044 and p = 0.014). The EQ-5D-5L score was significantly lower in patients with a ≥20 mmHg transvalvular gradient than those with a <20 mmHg (0.74 ± 0.25 vs. 0.84 ± 0.18, p = 0.014). CONCLUSIONS: Our results show that an iEOA <0.65 cm2/m2 is significantly associated with impaired postoperative health-related quality of life. Newer generation prostheses, transcatheter valve implantation, and root enlargement techniques should be kept in mind in preoperative planning.

Robotic-assisted cardiac surgery without lung isolation utilizing single-lumen endotracheal tube intubation.

OBJECTIVES: This study assessed the feasibility and outcomes of performing robotic cardiac surgery without lung isolation using single-lumen (SL) endotracheal tube intubation. METHODS: Between 2013 and 2017, 132 patients underwent robotically-assisted atrial septal defect closure. A retrospective analysis was performed of 23 patients (11 males, mean age 30.9 ± 5 years) who underwent robotic surgery with double-lumen (DL) endotracheal tube intubation (group 1) compared with 109 patients (57 males, mean age 32.4 ± 7.5 years) undergoing the same procedure with SL endotracheal intubation (group 2). The patient groups were compared in terms of demographic characteristics, operative data, and complications. The technical feasibility of the robotic procedure without lung isolation was evaluated. RESULTS: There were no mortality, intraoperative complication, and conversion. Mean total anesthesia time was significantly decreased in the SL intubation group (238.3 ± 22.4 vs 227.2 ± 21.2 minutes; P = .025). First-pass intubation success was significantly higher in the SL intubation group (17 [73.9%] vs 98 [89.9%] patients; P = .032). Mean ventilation time (10.9 ± 5.3 hours), intensive care unit stay (16.8 ± 10.1 hours), and the length of hospital stay (3.8 ± 1.2 days) was significantly decreased in patients with SL tube (P < .05). Unilateral reexpansion pulmonary edema was observed in five (21.7%) patients with DL tube, whereas no patient with SL tube had this complication. CONCLUSIONS: SL endotracheal tube intubation without lung isolation is a feasible and safe airway alternative in robotic cardiac procedures. This approach resulted in shorter anesthesia time, ventilation time and the length of hospital stay. Port placement and robotic set-up can be uneventfully performed without lung isolation.

Transcatheter closure vs totally endoscopic robotic surgery for atrial septal defect closure: A single-center experience.

BACKGROUND: Transcatheter closure is the preferred method for atrial septal defect (ASD) closure. Robotic surgery has become the least invasive technique for ASD closure. Therefore, we sought to evaluate the outcomes in patients who underwent ASD closure with transcatheter or robotic surgery techniques. METHODS: A total of 462 patients underwent totally endoscopic robotic (n = 217) or transcatheter ASD closure (n = 245). Demographic data, perioperative data, and outcomes were compared. RESULTS: The mean age was lower in the robotic surgery group than the transcatheter group (31.4 ± 11.8 vs 39.4 ± 13.2 years; P = .001). Ventilation time, intensive care unit (ICU) stay, and hospital stay was significantly lower in the transcatheter group. The postoperative new-onset neurological event was seen in one (0.5%) patient in robotic surgery, and four (1.6%) patients in the transcatheter closure group. New-onset atrial fibrillation was found to be higher in transcatheter closure (two vs seven patients; P = .133) group. Surgical conversion to a larger incision occurred in two patients (1%) in robotic surgery, while two patients (0.5%) underwent emergency median sternotomy due to device embolization to the main pulmonary artery. There was no mortality in both groups. During follow-up, one patient (0.5%) who underwent robotic surgery was reoperated, and two patients (0.8%) who underwent transcatheter procedure required surgical intervention due to device migration and severe residual shunting (P = .635). CONCLUSION: Both transcatheter and robotic surgery approaches had excellent outcomes but transcatheter closure had shorter hospital and ICU stays. Robotic surgery provides a similar complication risk that can be comparable to the transcatheter approach as well as patient comfort and cosmetic advantage over the other surgical techniques.

Effect of Pulsatile Cardiopulmonary Bypass in Adult Heart Surgery.

BACKGROUND: This study aimed to examine the effect of pulsatile flow pattern on tissue perfusion, particularly cerebral tissue perfusion, at pre-determined intervals during CPB, as well as its effects on postoperative morbidity and mortality. METHODS: This retrospective study included 134 adult patients, who underwent cardiac surgery with cardiopulmonary bypass (CPB). Patients were grouped based on the flow pattern used during CPB: non-pulsatile CPB group (N = 82) and pulsatile CPB group (N = 52). Cerebral oxygen saturation, arterial pH and arterial lactate levels were measured at four time points, during the operation and the 2 groups were compared with regard to changes over time as well as differences in postoperative outcomes. RESULTS: The 2 groups were similar, in terms of mean values and intraoperative changes in cerebral oxygen saturation and arterial pH. Non-pulsatile CABG group had significantly higher arterial lactate levels over the measurement period, which was not affected by the timing of the measurements. Postoperative drainage, duration of ventilation and duration of hospital stay significantly were higher and postoperative blood urea nitrogen significantly was lower in the non-pulsatile CPB group. Other postoperative outcomes were similar across the groups. CONCLUSION: Findings of this study do not support the superiority of pulsatile flow pattern during CPB, in terms of cerebral oxygen saturation or postoperative mortality/morbidity. Further and larger comparative studies are warranted before pulsatile blood flow pattern can be established as a routine clinical method.

Totally Endoscopic Robotic-Assisted Cardiac Surgery in Children.

Robotic surgery for intracardiac pathologies in children is relatively uncommon. This study presents our initial experience with robotic-assisted cardiac surgery in children. We also present the feasibility and safety of robotic surgery in children. From May 2013 to June 2018, 30 children underwent totally endoscopic robotic atrial septal defect closure (n = 22), right-sided (n = 5) or left-sided (n = 1) partial anomalous pulmonary venous connection repair, tricuspid valve annuloplasty (n = 4), and mitral valve replacement (n = 2, due to Barlow and rheumatic diseases). The mean age of the patients was 16.1 ± 1.1 years (range, 13-17) and the mean weight was 56.7 ± 0.1 kg (range, 42-77). Associated anomalies included left persistent superior vena cava (n = 2) and the absence of innominate vein (n = 1). All procedures were completed uneventfully. Operation time was 4.1 ± 0.6 h. No patient was converted to thoracotomy or sternotomy. Cardiopulmonary bypass and aortic clamping times were 90.6 ± 28.0 (range, 45-136) and 48.6 ± 24.9 (range, 15-94) min, respectively. The mean ventilation time was 3.7 ± 1.2 h and hospital stay time was 3.3 ± 0.7 days. No right phrenic nerve injury, hemorrhage, or blood transfusion were noted. One patient had postoperative pneumothorax, and 1 had supraventricular arrhythmia. Follow-up was a mean of 1.7 years (range, 1-52 months). Patients were healthy and no residual intracardiac defect was observed on echocardiography examinations. There was no operative or follow-up mortality. Robotically assisted cardiac surgery is a feasible and safe approach in selected pediatric patients. In the future, new generation robotic devices may offer an alternative surgical approach in cardiac surgery for younger children with lower body weight.

Comparison of Continuous and Interrupted Suturing Techniques in Ventricular Septal Defect Closure.

BACKGROUND: Our goal is to evaluate postoperative outcomes of continuous versus interrupted suturing techniques in ventricular septal defect (VSD) closure surgery. METHODS: The study included 286 patients with isolated VSD who underwent VSD closure surgery between June 2010 and April 2017. VSD closure was performed by using the interrupted suturing technique in group 1 (n = 74, 25.9%) and the continuous suturing technique in group 2 (n = 212, 74.1%). The groups were compared in terms of mortality and rates of clinical morbidities such as infection and complete atrioventricular (AV) block. RESULTS: Early mortality occurred in 3 cases in group 1 (4.0%) and 5 cases in group 2 (2.3%). There was no late mortality in either group. One patient from both groups required extracorporeal membrane oxygenation (ECMO) at postoperative 48 hours. Five patients in group 1 (6.8%) and 11 patients in group 2 (5.2%) developed complete AV block postoperatively and received permanent pacemaker implants. CONCLUSION: Complication rates were similar between the patient groups operated on by using continuous and interrupted suturing techniques in our study, suggesting that neither technique is superior for VSD closure surgery.

Surgical Transapical Approach for Prosthetic Mitral Paravalvular Leak Closure: Early Results.

The objective is to demonstrate safety and early clinical results of surgical transapical closure of paravalvular leaks (PVLs) following mitral valve replacement in significant regurgitation. Between March 2014 and February 2015, 12 patients (mean age 52.1 ± 6.0 years, 66.6% male) with severe symptomatic mitral PVLs (n = 13) underwent surgical transapical closure procedure through left mini-thoracotomy. All patients were in NYHA functional class III-IV and median logistic EuroSCORE was 24.2 ± 6.4% (range, 13.5-34.6%). Indications were heart failure (n = 10) and symptomatic hemolysis (n = 2) due to severe mitral regurgitation (MR). Amplatzer Vascular Plug-III devices (n = 9) were used for smaller and regular defects; whereas Atrial Septal Defect closure devices (n = 4) were used for larger defects. Technical success was achieved in 10 (83.3%) patients. One (8.5%) patient with 2 + MR was treated medically. A patient with residual 4 + MR underwent re-operation. There was no procedure-related complication including mortality, device migration, embolization, or cardiac laceration. Mean procedure and fluoroscopy times were 166.4 ± 39.5 (range, 90-210) and 25.7 ± 17.3 (range, 16-64) minutes, respectively. The mean intensive care and hospital stays were 2.1 ± 1.3 and 10.3 ± 6.5 days, respectively. Clinical efficacy was achieved in 9 (75%) of 12 patients at early follow-up of 8.5 ± 2.1 months. NYHA status was class II in two patients, and no hemolytic anemia was diagnosed. Echocardiographic studies revealed a significant reduction of preoperative MR (3-4+) to less than 1+ MR after operations (P < 0.05). Surgical transapical approach to PVL closure is a safe and effective procedure following mitral valve replacement. Early results show that this procedure can be an alternative to re-operation for high-risk patients. Further studies are needed to prove its effectiveness in the long term.

A New Specific Device in Transcatheter Prosthetic Paravalvular Leak Closure: A Prospective Two-Center Trial.

BACKGROUND: This study sought to compare various outcomes among a new specifically designed transcatheter paravalvular leak closure (TPVLC) device and the devices that are being utilized off-label. METHODS: Between April 2012 and January 2015, in a prospective two-center study, 52 patients who needed surgical reintervention due to a hemodynamically significant prosthetic paravalvular leak were studied. This study population was divided into two groups. Group I was composed of 32 patients who underwent paravalvular leak (PVL) closure with the currently available devices that are being utilized off-label, while group II consisted of 20 patients who were treated with the new specifically designed Occlutech PVL device. RESULTS: Demographic and clinical variables indicated a higher rate of atrial fibrillation (P = 0.027) and chronic obstructive airway disease (P = 0.009) in group II. The apical approach was the most commonly used intervention route used for group II (P = 0.019). The procedural success rate was 100% (29 of 29 leaks) in group II while the rate was 92% (39 of 42 leaks) in group I. However, more secondary events were observed in group I, but they did not reach statistical significance (8 vs. 1, P = 0.064). CONCLUSIONS: With its high procedural success rate and encouraging outcome results, the Occlutech device seems to satisfy the expectations of a specifically designed PVL closure device. © 2016 Wiley Periodicals, Inc.

Robot-Assisted Repair of Right Partial Anomalous Pulmonary Venous Return.

Partial anomalous venous return from the right lung to the right atrium is a rare congenital heart anomaly in adults. We report a 20-year-old female, who presented with right partial anomalous pulmonary venous return and an associated inferior atrial septal defect. A complex repair was successfully done through a right atriotomy approach using a robotic surgical system. doi: 10.1111/jocs.12753 (J Card Surg 2016;31:394-397).

Staged or Combined Approach for Carotid Endarterectomy in Patients Undergoing Coronary Artery Bypass Grafting: A 5-Year-Long Experience.

BACKGROUND: Optimal surgical approach for patients with hemodynamically significant carotid and coronary disease remains controversial. We analyzed our 5-year experience and compared early and long-term outcome following staged and combined carotid and coronary artery bypass. METHODS: 312 consecutive patients undergoing carotid endarterectomy and coronary artery bypass between 2008 and 2013 were prospectively enrolled in the study. Patients were scheduled for a staged (carotid endarterectomy followed by coronary artery bypass within 1 week) procedure (Group S) unless they were unstable in terms of cardiac status (were deemed to a combined procedure; Group C). All patient data including demographics, risk factors, immediate perioperative events, 30-day, and long-term outcome were prospectively recorded and then analyzed. Groups S and C were compared for pre- and perioperative data as well as immediate, 30-day, and long-term survival. A P value less than .05 was considered significant. Survival analysis was made using Kaplan-Meier method and log-rank test. RESULTS: Group S included 204 patients and Group C included 108 patients. Preoperative demographics and clinical data were similar in the two groups except that preoperative cerebrovascular events were more common in Group C (31.7% versus 22.22%, P = .036) and bilateral carotid disease was more common in Group S. The EuroSCORE was higher in Group C (2.91 versus 2.65, P = .013). Carotid surgery techniques were similar; intraluminal shunting was more frequent in group C than group S (33.33% versus 9.88%, P = .001). Additional cardiac procedures in addition to coronary surgery was predominant in Group C. 30-day neurological adverse event rates, ICU, and hospital stay were significantly higher in Group C. The 30-day mortality was also sigficantly higher in Group C (1.96% versus 4.62%, P = .001). CONCLUSION: Staged and combined surgical approaches yield comparable outcomes. A staged approach may provide a more favorable neurological outcome with significantly reduced need for intraluminal shunting. Long-term outcome is, however, similar.

Incidental biliary cystadenoma mimicking liver metastasis in a gastric cancer patient.

Biliary cystadenoma represents a rare benign cystic hepatic neoplasm with premalignant potential. The diagnosis is usually difficult, and imaging methods may not be possible to clarify the pathology. It can be hard to determine, particularly in patients with a previous cancer history that has high metastatic potential in the liver. We presented a 53-year-old man with a newly diagnosed liver mass that was suspicious for metastasis 2 years after gastric cancer surgery and histological analysis confirmed the diagnosis of biliary cystadenoma.

Laparoscopic splenectomy for a wandering spleen causing chronic pelvic pain.

Wandering spleen is a rare condition with a reported incidence of less than 0.5% in which the spleen migrates from its normal anatomical location to any other position in the abdomen. Women constitute 80% of cases and one third of the overall patients are children. It has different clinical presentations such as asymptomatic, painless mass in the abdomen, intermittent abdominal pain and acute abdomen due to torsion of the vascular pedicle. Here we present a case of wandering spleen causing chronic pelvic pain. Laparoscopic splenopexy was the treatment choice but it could not be performed due to huge size of the wandering spleen.

Prevention and acute management of biliary injuries during laparoscopic cholecystectomy: Expert consensus statement.

Gallstone disease is very common and laparoscopic cholecystectomy is one of the most common surgical procedures all over the world. Parallel to the increase in the number of laparoscopic cholecystectomies, bile duct injuries also increased. The reported incidence of bile duct injuries ranges from 0.3% to 1.4%. Many of the bile duct injuries during laparoscopic cholecystectomy are not due to inexperience, but are the result of basic technical failures and misinterpretations. A working group of expert hepatopancreatobiliary surgeons, an endoscopist, and a specialist of forensic medicine study searched and analyzed the publications on safe cholecystectomy and biliary injuries complicating laparoscopic cholecystectomy under the organization of Turkish Hepatopancreatobiliary Surgery Association. After a series of e-mail communications and two conferences, the expert panel developed consensus statements for safe cholecystectomy, management of biliary injuries and medicolegal issues. The panel concluded that iatrogenic biliary injury is an overwhelming complication of laparoscopic cholecystectomy and an important issue in malpractice claims. Misidentification of the biliary system is the major cause of biliary injuries. To avoid this, the "critical view of safety" technique should be employed in all the cases. If biliary injury is identified intraoperatively, reconstruction should only be performed by experienced hepatobiliary surgeons. In the postoperative period, any deviation from the expected clinical course of recovery should alert the surgeon about the possibility of biliary injury.

Life Saver: Aortic Wrapping.

Reoperative aortic root reconstruction remains a formidable surgical challenge. Thereof, the wrapping of Dacron graft using remnants of native aorta may be reasonable to avoid complications such as bleeding and infection. Our case that had a modified Bentall procedure at our institute was reoperated because of discontinuity between left ventricular outflow and valved aortic conduit. During reoperation, proximal portion of the valved conduit was partially separated from its attachment in the left ventricular outflow tract. The residual native aorta that was wrapped around the Dacron graft was like in a shape of sac. This technique may play a major role in preventing rupture of the ascending aorta in case of separation of valved conduit from left ventricular outflow.

Concomitant Transapical Transcatheter Valve Implantations: Edwards Sapien Valve for Severe Mitral Regurgitation in a Patient with Failing Mitral Bioprostheses and JenaValve for the Treatment of Pure Aortic Regurgitation.

Transcatheter valve implantation is a novel interventional technique, which was developed as an  alternative therapy for surgical aortic valve replacement in inoperable patients with severe aortic stenosis. Despite limited experience in using transcatheter valve implantation for mitral and aortic regurgitation, transapical transcatheter aortic valve implantation and valve-in-valve implantation for degenerated mitral valve bioprosthesis can be performed in high-risk patients who are not candidates for conventional replacement surgery. In this case, we present the simultaneous transcatheter valve implantation via transapical approach for both degenerated bioprosthetic mitral valve with severe regurgitation and pure severe aortic regurgitation.

Acute kidney injury after surgical treatment of failed endovascular aneurysm repair.

Background: This study aims to report the incidence of acute kidney injury following surgical reconstruction after a failed endovascular aneurysm repair (EVAR) in patients with abdominal aortic aneurysms. Methods: This retrospective study included 44 patients (39 males, 5 females; mean age: 70±11.3 years; range, 35 to 84 years) who underwent emergency or elective surgical reconstruction after failed EVAR between February 2015 and January 2019. Patients were divided into two groups: acute kidney injury group and no acute kidney injury group. The primary end-point of the study was to evaluate the development of acute kidney injury following surgery. The secondary end-points included the 30-day and one-year mortality rates. Results: Surgical reconstruction of the abdominal aorta was performed electively in 29 (65.9%) patients and urgently in 15 (34.1%) patients. Acute kidney injury occurred in 12 (27.3%) patients. The interval from endovascular aneurysm repair to surgical reconstruction was statistically significantly higher in the no acute kidney injury group than in the acute kidney injury group (24.6±11.5 and 18.1±13.3 months, respectively; p=0.145). The mean abdominal aortic aneurysm diameter, neck angulation, and neck diameter were statistically significantly higher in the acute kidney injury group than in the no acute kidney injury group (p=0.001, p=0.009, and p<0.001, respectively). No statistically significant difference was observed between the acute kidney injury and no acute kidney injury groups for the overall 30-day mortality (p=0.185) and oneyear mortality (p=0.999). Conclusion: Acute kidney injury is not uncommon after the surgical reconstruction of a failed EVAR. Aneurysm-related anatomical factors may have an impact on the development of postoperative acute kidney injury. Comprehensive surgical planning should be performed for open abdominal aortic surgery after a failed EVAR.

Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

Management of hemangioma of the liver: surgical therapy or observation?

BACKGROUND: Elective surgery for liver hemangioma is controversial. We reviewed long-term outcomes following elective hepatectomy or observation only for symptomatic and asymptomatic liver hemangioma. METHODS: All patients (n = 307) with liver hemangioma referred to our hospital for surgical evaluation from January 1988 to December 2009 were identified, and imaging results, tumor characteristics, surgical indication, surgical mode, outcome of observation, clinical and/or postoperative outcome, and adverse events were retrospectively evaluated. RESULTS: Complete median follow-up for 246 patients was 124 months. Elective surgery was performed in 103 patients (symptomatic [n = 62] and asymptomatic [n = 41]). Postoperative morbidity occurred in 17 % of the patients and was significantly lower in asymptomatic patients (p = 0.002). No perioperative mortality was registered. Surgery relieved complaints in most (88 %) patients. In the observation group (n = 143), 56 % of patients had persistent or new onset of hemangioma-associated symptoms. Major hemangioma-related complications occurred in 12 patients (9 %) during the follow-up period, and 2 patients died after traumatic hemangioma rupture. Overall the rate of adverse events was by trend lower in the surgical group than in the observation group (35 versus 57 %; p = 0.08). CONCLUSIONS: The majority of patients with liver hemangioma can be safely managed by clinical observation. In a subset of patients, especially those with giant hemangioma and/or occurrence of symptoms, surgical treatment could be considered and is justified in high-volume centers.
