METHODS: A retrospective review of medical records (2013-2022) of major traumatic vascular injuries, focusing on injury profiles, treatment modalities, and clinical outcomes.
RESULTS: Thirty patients with 48 vessel injuries were included. Firearms were the leading mechanism, accounting for 43.3% (n = 13) of cases. We identified 29 arterial injuries and 19 venous injuries, with 30 (62.5%) of the overall injuries occurred in the lower extremities. Shock (17; 56.7%) and associated injuries (25; 83.3%) were common. Surgery was the most common management strategy. Autologous bypass graft was the most frequently performed procedure for arterial injuries (8; 42.1%), while ligation dominated in venous injuries (9; 64.3%). Blood transfusion requirements (24; 82.7%) and post-operative prescription of anticoagulant and antiplatelet agents (12; 41.4%) were similar for arterial and venous injuries (p > 0.05). Three patients demised, resulting in a 90% survival rate. Neither the mechanism of injury, anatomical location, and presence of shock on arrival nor the baseline hemoglobin level served as predictors of mortality.
CONCLUSION: Intensive resuscitation with blood transfusion and prompt surgical intervention achieve favorable survival rates for pediatric traumatic vascular injuries. Optimal post-operative anticoagulant and antiplatelet regimens remain unclear.
Materials and Methods: We performed a retrospective cohort study of nine cases of unruptured basilar tip aneurysm referred to the Fujita Health University Banbuntane-Hotokukai Hospital, Japan. The objective of the study was to analyze the surgical outcomes of unruptured basilar tip aneurysm.
Results: Nine patients with unruptured basilar tip aneurysm were referred to our hospital between 2015 and 2017. The median size of the aneurysm and age were 4.00 mm (interquartile range [IQR] = 3.25-6.75 mm) and 58 years (IQR = 54-70 years), respectively. Five patients (55.6%) were presented with multiple intracranial aneurysms. Surgical adjuncts such as intraoperative neuromonitoring, intraoperative indocyanine green (ICG) angiography with dual-image videoangiography (DIVA), and neuroendoscope were used. Two patients developed transient postoperative oculomotor nerve palsy which resolved spontaneously. The median duration of surgery and days of hospitalization were 292 min (IQR = 237.5-350.5 min) and 12 days (IQR = 12-25 days), respectively. There was no mortality recorded in this case series.
Conclusion: Microsurgical clipping of basilar tip aneurysm is safe in unruptured basilar tip aneurysm with a low risk of postoperative mortality or morbidity. All complications reported in this case series were transient with no long-term sequalae. The improved safety profile of microsurgical technique is due to the availability of intraoperative neuromonitoring, neuroendoscope, ICG, and DIVA. The application of multimodality technique in neurovascular surgery has also helped to achieve complication avoidance. The obliteration of the aneurysmal sac helps to restore the laminar blood flow in the bifurcation and distal blood vessels and improves the brain perfusion.
BACKGROUND: MINS has been independently associated with 30-day mortality after noncardiac surgery. The characteristics and prognostic importance of MINS in vascular surgery patients are poorly described.
METHODS: This was an international prospective cohort study of 15,102 noncardiac surgery patients 45 years or older, of whom 502 patients underwent vascular surgery. All patients had fourth-generation plasma troponin T (TnT) concentrations measured during the first 3 postoperative days. MINS was defined as a TnT of 0.03 ng/mL of higher secondary to ischemia. The objectives of the present study were to determine (i) if MINS is prognostically important in vascular surgical patients, (ii) the clinical characteristics of vascular surgery patients with and without MINS, (iii) the 30-day outcomes for vascular surgery patients with and without MINS, and (iv) the proportion of MINS that probably would have gone undetected without routine troponin monitoring.
RESULTS: The incidence of MINS in the vascular surgery patients was 19.1% (95% confidence interval (CI), 15.7%-22.6%). 30-day all-cause mortality in the vascular cohort was 12.5% (95% CI 7.3%-20.6%) in patients with MINS compared with 1.5% (95% CI 0.7%-3.2%) in patients without MINS (P < 0.001). MINS was independently associated with 30-day mortality in vascular patients (odds ratio, 9.48; 95% CI, 3.46-25.96). The 30-day mortality was similar in MINS patients with (15.0%; 95% CI, 7.1-29.1) and without an ischemic feature (12.2%; 95% CI, 5.3-25.5, P = 0.76). The proportion of vascular surgery patients who suffered MINS without overt evidence of myocardial ischemia was 74.1% (95% CI, 63.6-82.4).
CONCLUSIONS: Approximately 1 in 5 patients experienced MINS after vascular surgery. MINS was independently associated with 30-day mortality. The majority of patients with MINS were asymptomatic and would have gone undetected without routine postoperative troponin measurement.
METHODS: Patients with hand amputation who underwent replantation or revascularization from 2005 to 2012 were identified and reviewed for patient characteristics, amputation characteristics and survival rates. Successfully treated patients were interviewed to assess the functional outcome using Quick Disability of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and Michigan Hand Outcome Questionnaire (MHQ). Statistical analysis was performed to evaluate outcome and elicit predictive factors.
RESULTS: Fifty-five patients were enrolled: 37 (67.3%) underwent replantation and 18 (32.7%) underwent revascularization. The overall success rate of 78% ( n = 43) was within the range of previously reported data (61.6% to 96.0%). Ischaemic time <6 h provided significantly better survival rates ( p < 0.05). Functional outcomes were successfully assessed in 34 patients (79%), at a mean follow-up of 40 months (range 11-93 months). The overall Quick-DASH and MHQ scores were 42.82 ± 23.69 and 60.94 ± 12.82, respectively. No previous reports of functional outcome were available for comparison. Both Quick-DASH ( p = 0.001) and MHQ scores ( p < 0.001) were significantly higher for finger injuries, followed by thumb, wrist and palm injuries.
CONCLUSION: Ischaemic time and level of injury are important predictors of success rate of replantation and revascularization of amputated upper limb appendages.
METHODS: POISE-2 was a blinded, randomized trial of patients having non-cardiac surgery. Patients were assigned to perioperative aspirin or placebo. The primary outcome was a composite of death or myocardial infarction at 30 days. Secondary outcomes included: vascular occlusive complications (a composite of amputation and peripheral arterial thrombosis) and major or life-threatening bleeding.
RESULTS: Of 10 010 patients in POISE-2, 603 underwent vascular surgery, 319 in the continuation and 284 in the initiation stratum. Some 272 patients had vascular surgery for occlusive disease and 265 had aneurysm surgery. The primary outcome occurred in 13·7 per cent of patients having aneurysm repair allocated to aspirin and 9·0 per cent who had placebo (hazard ratio (HR) 1·48, 95 per cent c.i. 0·71 to 3·09). Among patients who had surgery for occlusive vascular disease, 15·8 per cent allocated to aspirin and 13·6 per cent on placebo had the primary outcome (HR 1·16, 0·62 to 2·17). There was no interaction with the primary outcome for type of surgery (P = 0·294) or aspirin stratum (P = 0·623). There was no interaction for vascular occlusive complications (P = 0·413) or bleeding (P = 0·900) for vascular compared with non-vascular surgery.
CONCLUSION: This study suggests that the overall POISE-2 results apply to vascular surgery. Perioperative withdrawal of chronic aspirin therapy did not increase cardiovascular or vascular occlusive complications. Registration number: NCT01082874 ( http://www.clinicaltrials.gov).
METHODS: This is a retrospective study done in neonates and infants up to 3 months of age with duct-dependent pulmonary circulation who underwent DS from January 2014 to December 2015. Post-stenting PA growth, surgical outcomes of PA reconstruction, post-surgical re-interventions, morbidity and mortality were analysed.
RESULTS: During the study period, 46 patients underwent successful DS, of whom 38 underwent presurgery catheterization and definite surgery. There was significant growth of PAs in these patients. Biventricular repair was done in 31 patients while 7 had univentricular palliation. Left PA augmentation was required in 13 patients, and 10 required central PA augmentation during surgery. The mean follow-up period post-surgery was 4.5 ± 1.5 years. No significant postoperative complications were seen. No early or follow-up post-surgery mortality was seen. Four patients required re-interventions in the form of left PA stenting based on the echocardiography or computed tomography evidence of significant stenosis.
CONCLUSIONS: DS provides good short-term palliation and the growth of PAs. However, a significant number of stented patients require reparative procedure on PAs at the time of surgical intervention. Acquired changes in the PAs following DS may be the reason for reintervention following PA reconstruction.
Subject and Methods: A total of 27 patients underwent surgery between 2001 and 2015, and they were followed up for a mean period of 6.4 ± 4.1 years. Out of the 27 patients, 14 (51.9%) were infants. The median age at repair was 9.8 months. Preoperative intubation was required in six patients (22.2%), and 11 patients (40.7%) had symptoms of respiratory distress. The pulmonary valve was replaced with a valved conduit in 15 patients (55.6%), monocusp valve in 6 patients (22.2%), and a transannular patch in 6 patients (22.2%). Reduction pulmonary arterioplasty was done in all patients.
Results: The overall 10-year survival was 82.1%. There was 81.1% overall freedom from re-intervention at 10 years. No statistically significant difference was found in 10-year survival (P = 0.464) and reoperation rates (P = 0.129) between valved conduit, monocusp, or transannular patch techniques. Older children had statistically significantly longer survival (P = 0.039) and freedom from re-intervention (P = 0.016) compared to infants. Patients without respiratory complications had 100% 10-year survival and 93.3% freedom from reoperation at 10 years compared to 55.6% and 60.1%, respectively, for patients with respiratory complications.
Conclusion: There has been improvement in surgical results for APVS over the years. However, it still remains a challenge to manage infants and patients with persistent respiratory problems.
STUDY DESIGN: Clinical audit report.
PLACE AND DURATION OF STUDY: Hospital Sultanah Aminah Johor Bahru, Malaysia, from March 2016 to May 2017.
METHODOLOGY: Data were collected retrospectively from all 127 patients who underwent CABG with saphenous vein grafts, either with CVH technique (n=68), or MIVH technique (n=59) performed with Vasoview system. The rate of wound dehiscence was evaluated. Patients with severe wound dehiscence that required readmission and surgical intervention were identified for further evaluation.
RESULTS: There was total 26.8% of wound dehiscence in our study, which was not appreciably different between two groups (p=0.092). Patient with severe wound breakdown that required surgical intervention was significantly less in MIVH group (1/59, 1.7%) compared to CVH group (8/68, 11.8%, p=0.037). There was no significant difference in readmission rate between MIVH and CVH group (p=0.574).
CONCLUSION: There is significant reduction in severity of wound dehiscence post-saphenous vein harvesting among CABG patients with MIVH technique. However, there is no statistical difference in wound dehiscence and readmission rate between MIVH and CVH technique.
