Multifocal hepatic abscess post-ERCP.

A woman in her 40s presented to hospital with cholangitis. A magnetic resonance cholangiopancreatography showed a moderately dilated common bile duct and mild intrahepatic duct dilatation with sludge. She underwent a successful endoscopic retrograde cholangiopancreatography (ERCP) and sphincteroplasty. She subsequently developed recurrence of fevers and abdominal pain with rising inflammatory markers. Initial investigations and imaging were unremarkable. A positron emission tomography scan demonstrated multiple fluorodeoxyglucose (FDG)-avid hepatic lesions, and subsequent imaging confirmed multifocal liver abscesses without a drainable collection. The patient was managed with intravenous co-amoxiclav initially before switching to oral antibiotics, however, represented 1 week later with similar symptoms. Her antibiotic coverage was broadened to intravenous pipercillin-tazobactam, and she was discharged on this with follow-up in clinic. This case report highlights the rare complication of hepatic abscesses following ERCP and the importance of considering this as a differential in patients who present with sepsis following the procedure.

Randomized controlled trial to evaluate the effect of prophylactic amiodarone versus dexmedetomidine on reducing the incidence of postoperative junctional ectopic tachycardia after pediatric open heart surgery.

Background: Junctional ectopic tachycardia (JET) is the most common arrhythmia after pediatric open-heart surgeries (OHS), causing high morbidity and mortality. As diagnosis is often missed in patients with minimal hemodynamic instability, its incidence depends on active surveillance. A prospective randomized trial evaluated the efficacy and safety of prophylactic amiodarone and dexmedetomidine to prevent and control postoperative JET. Methods: Consecutive patients aged under 12 years were randomized into amiodarone, dexmedetomidine (initiated during anesthetic induction) and control groups. Outcome measures included incidence of JET, inotropic score, ventilation, and intensive care unit (ICU) duration and hospital stay, as well as adverse drug effects. Results: Two hundred and twenty-five consecutive patients with a median age of 9 months (range 2 days-144 months) and a median weight of 6.3 kg (range 1.8 kg-38 kg) were randomized with 70 patients each to amiodarone and dexmedetomidine groups, and the rest were controls. Ventricular septal defect and Fallot's tetralogy were the common defects. The overall incidence of JET was 16.4%. Syndromic patients, hypokalemia, hypomagnesemia, longer bypass, and cross-clamp duration were the risk factors for JET. Patients with JET had significantly prolonged ventilation (P = 0.043), longer ICU (P = 0.004), and hospital stay (P = 0.034) than those without JET. JET was less frequent in amiodarone (8.5%) and dexmedetomidine (14.2%) groups compared to controls (24.7%) (P = 0.022). Patients receiving amiodarone and dexmedetomidine had significantly lower inotropic requirements, lower ventilation duration (P = 0.008), ICU (P = 0.006), and hospital stay (P = 0.05). Adverse effects such as bradycardia and hypotension after amiodarone and ventricular dysfunction after dexmedetomidine were not significantly different from controls. Conclusion: Prophylactic amiodarone or dexmedetomidine started before OHS is effective and safe for the prevention of postoperative JET.

Tetra ostial coronary arterial anatomy-A rare pattern in transposition.

BACKGROUND: Meticulous transfer of coronary arteries is of crucial importance in transposition and determines the success of the switch procedure. This report describes a coronary arterial anatomy consisting of four separate ostia from the two facing sinuses in a 6-month-old infant presenting with transposition and ventricular septal defect. CONCLUSION: Being a rare coronary arterial pattern not described in previous coding systems, the surgeon would do well to be aware of this possibility while performing the switch procedure.

The heterotaxy syndrome: associated congenital heart defects and management.

Heterotaxy syndrome (HS) constitutes a spectrum of anomalies arising from embryological errors that result in abnormalities of lateralization involving thoraco-abdominal viscera and culminate in loss of normal asymmetric arrangement of these organs. Besides the unique challenges involved in planning and execution of surgical procedures aimed at correction or palliation of these anomalies, they have the potential to cause profound physiological and immunological consequences in the individual patient due to their cardiac and extra-cardiac manifestations. This article aims to review the literature on this rare and extraordinary subset of developmental anomalies with the intention of familiarizing the reader on the modes of presentation, manifestations, and the variations thereof while dealing with this anomaly. In our institutional experience with HS, 75 consecutive patients were seen between January 2011 and September 2018. Of these, 48 (64%) were confirmed to have isomerism of right atrial appendages (IRAA) and the rest had isomerism of left atrial appendages (ILAA). The cardiac and extra-cardiac manifestations of these patients were listed out. Fifty-four patients (34 with IRAA and 20 with ILAA) underwent 83 surgical procedures. While 49 patients were palliated on the univentricular pathway, 5 underwent biventricular repair. The in-hospital mortality was 7 (13%) in both groups combined (5 for patients with IRAA and 2 for ILAA). In conclusion, the surgical management of HS is associated with satisfactory outcomes in current era.

Are early palliative procedures providing an adequate long-term benefit in young cyanotic infants from developing countries, despite advances in surgery and interventions?

OBJECTIVES: Ductal stents, right ventricular outflow tract stents, and aortopulmonary shunts are used to palliate newborns and infants with reduced pulmonary blood flow. Current long-term outcomes of these palliations from resource-restricted countries are unknown. METHODS: This single-centre, retrospective, observational study analysed the technical success, immediate and late mortality, re-interventions, and length of palliation in infants ≤5 kg who underwent aortopulmonary shunts, ductal, and pulmonary outflow stents. Patients were grouped by their anatomy. RESULTS: There were 69 infants who underwent one of the palliations. Technical success was 90% for aortopulmonary shunts (n = 10), 91% for pulmonary outflow stents (n = 11) and 100% for ductal stents (n = 48). Early mortality within 30 days in 12/69 patients was observed in 20% after shunts, 9% after pulmonary outflow stents, and 19% after ductal stents. Late mortality in 11 patients was seen in 20% after shunts, 18% after outflow stents, and 15% after ductal stents. Seven patients needed re-interventions; two following shunts, one following outflow stent, and four following ductal stents for hypoxia. Among the anatomical groups, 10/12 patients with pulmonary atresia, intact ventricular septum survived after valvotomy and ductal stenting. Survival to Glenn shunt after ductal stent for pulmonary atresia, intact ventricular septum and diminutive right ventricle was very low in two out of eight patients, but very good (100%) for other univentricular hearts. Among 35 patients with biventricular lesions, 22 survived to the next stage. CONCLUSIONS: Cyanotic infants, despite undergoing technically successful palliation had a high inter-stage mortality irrespective of the type of palliation. Duct stenting in univentricular hearts and in pulmonary atresia with an intact ventricular septum and adequate sized right ventricle tended to have low mortality and better long-term outcome. Completion of biventricular repair after palliation was achieved only in 63% of patients, reflecting unique challenges in developing countries despite advances in intensive care and interventions.

Triage of patients with venous and lymphatic diseases during the COVID-19 pandemic - The Venous and Lymphatic Triage and Acuity Scale (VELTAS) : A consensus document of the International Union of Phlebology (UIP), Australasian College of Phlebology (ACP), American Vein and Lymphatic Society (AVLS), American Venous Forum (AVF), European College of Phlebology (ECoP), European Venous Forum (EVF), Interventional Radiology Society of Australasia (IRSA), Latin American Venous Forum, Pan-American Society of Phlebology and Lymphology and the Venous Association of India (VAI) This consensus document has been co-published in Phlebology [DOI: 10.1177/0268355520930884] and Journal of Vascular Surgery: Venous and Lymphatic Disorders [DOI: 10.1016/j.jvsv.2020.05.002].

The coronavirus disease 2019 (COVID-19) global pandemic has resulted in diversion of healthcare resources to the management of patients infected with SARS-CoV-2 virus. Elective interventions and surgical procedures in most countries have been postponed and operating room resources have been diverted to manage the pandemic. The Venous and Lymphatic Triage and Acuity Scale was developed to provide an international standard to rationalise and harmonise the management of patients with venous and lymphatic disorders or vascular anomalies. Triage urgency was determined based on clinical assessment of urgency with which a patient would require medical treatment or surgical intervention. Clinical conditions were classified into six categories of: (1) venous thromboembolism (VTE), (2) chronic venous disease, (3) vascular anomalies, (4) venous trauma, (5) venous compression and (6) lymphatic disease. Triage urgency was categorised into four groups and individual conditions were allocated to each class of triage. These included (1) medical emergencies (requiring immediate attendance), example massive pulmonary embolism; (2) urgent (to be seen as soon as possible), example deep vein thrombosis; (3) semi-urgent (to be attended to within 30-90 days), example highly symptomatic chronic venous disease, and (4) discretionary/non-urgent- (to be seen within 6-12 months), example chronic lymphoedema. Venous and Lymphatic Triage and Acuity Scale aims to standardise the triage of patients with venous and lymphatic disease or vascular anomalies by providing an international consensus-based classification of clinical categories and triage urgency. The scale may be used during pandemics such as the current COVID-19 crisis but may also be used as a general framework to classify urgency of the listed conditions.

Descending aortic translocation procedure for relief of bronchial compression in left aortic arch and right descending aorta.

Compression of the left bronchus by a right-sided descending aorta arising from a left aortic arch constitutes an exceedingly rare form of vascular ring. This manuscript describes the surgical technique that involves translocation of the descending aorta directly to the proximal ascending aorta, thereby relieving the bronchial compression.

Evidence-Based Clinical Practice Points for the Management of Venous Ulcers.

Venous ulcer is an extremely common aetiology of lower extremity ulceration, which affects approximately 1% population in most of the countries, and the incidence rate increases with age and female gender. Proper assessment and diagnosis of both the patient and ulcer are inevitable in order to differentiate venous ulcers from other lower extremity ulceration and to frame an adequate and individualised management plan. Venous ulcers generally persist for weeks to many years and are typically recurrent in nature. This consensus aims to present an evidence-based management approach for the patients with venous ulcers. Various management options for venous ulcers include compression therapy, minimally invasive procedures like sclerotherapy and ablation techniques, surgical procedures, debridement and medical management with micronised purified flavonoid fraction (MPFF). Compression therapy is the mainstay treatment for venous ulcer. However, in failure cases, surgery can be preferred. Medical management with MPFF as an adjuvant therapy to standard treatment has been reported to be effective and safe in patients with venous ulcer. In addition to standard therapy, diet and lifestyle modification including progressive resistance exercise, patient education, leg elevation, weight reduction, maintaining a healthy cardiac status and strong psychosocial support reduces the risk of recurrence and improves the quality of life in patients with venous ulcer.

Left aortic arch with right descending aorta and severe coarctation: an unusual "vascular clamp" with airway compression.

Left aortic arch with right descending aorta is a rare congenital anomaly. We describe the clinical presentation of this unusual anomaly associated with cardiorespiratory compromise from severe aortic obstruction and left main bronchus compression. The anatomical peculiarities, embryological basis, and surgical solutions are presented.

Anomalous origin of right pulmonary artery from innominate artery: Repair using pulmonary artery pedicled flap plasty.

Origin of the right pulmonary artery from innominate artery is an exceedingly rare anomaly. We report two cases with this anomaly that underwent surgical repair. The surgical technique described achieves tissue-to-tissue anastomosis using a pedicled flap from the main pulmonary artery.

Translocation of Intramural Coronary Artery During Switch Procedure: A New Technique.

Intramural course of a coronary artery is a rare association in patients with transposition of great arteries. Various techniques have been described for translocation of these during the arterial switch procedure, with mixed results. This report focuses on a novel technique that is reproducible and provides an alternative in this difficult subset of patients.

Pediatric heart transplant for unresectable primary cardiac tumor.

Surgery for primary cardiac tumors in children includes complete resection, partial resection, and cardiac transplantation. A pediatric heart transplant in this setting is associated with significantly higher mortality and poorer long-term outcome, and it is reserved for unresectable tumors. We recently performed an emergency pediatric heart transplant in a 7-year-old boy with an unresectable cardiac fibroma in the left ventricle.

The "excluding" suture technique for surgical closure of ventricular septal defects: A retrospective study comparing the standard technique.

BACKGROUND: Conventional methods of closure of ventricular septal defects involve placement of sutures 4-5 mm from the posterior inferior margin. This study compares the conventional method with an alternative technique wherein sutures are placed along the edge of the defect thereby "excluding" the conduction system and the tensor apparatus of the tricuspid valve from the suture line. MATERIALS AND METHODS: Between January 2013 and January 2016, 409 consecutive patients were retrospectively reviewed and divided into two matched groups. Group A (n = 174) underwent closure using the alternative technique and Group B (n = 235) with the conventional technique. Patients with isolated ventricular septal defects (VSDs) (n = 136) were separately analyzed as were infants within this subset. RESULTS: Immediate postoperative results were similar with no statistically significant differences in either group in terms of incidence of residual defects or postoperative tricuspid regurgitation. There was however a significantly increased incidence of post operative complete heart block (CHB) among patients in the conventional group (P = 0.02). Incidence of temporary heart block that reverted to sinus rhythm was also more in the conventional method group (Group B) (P = 0.03) as was right bundle branch block (P ≤ 0.05) in all the subsets of patients analyzed. CONCLUSION: Surgical closure of VSDs can be accomplished by placing sutures along the margins or away with comparable results. The incidence of CHB, however, seems to be less when the "excluding" technique is employed.

Scimitar syndrome: Surgical approach to an unusual anatomy of the scimitar vein.

Repair strategies in scimitar syndrome are varied and need to be individualized to the surgical anatomy. This report focuses on the repair achieved in a case with unusual anatomy of the scimitar vein.

Surgical Repair of Interrupted Aortic Arch and Interrupted Pulmonary Artery.

Interrupted aortic arch (IAA) is usually associated with ventricular septal defect and patent ductus arteriosus. We report surgical repair in a case of IAA, ventricular septal defect, and interruption of the pulmonary artery with the right pulmonary artery arising from the innominate artery through a separate ductus arteriosus.

The pressures of surgicel(®) in cardiac surgery.

Surgicel® is bioabsorbable hemostatic mesh, frequently packed around oozing surgical bed. We report two morbidities due to it. Following transannular patch repair for Fallot's tetralogy, Surgicel® was packed around distal main pulmonary artery. Echocardiography in the intensive care unit (ICU) showed right ventricular dysfunction due to extrinsic obstruction and complete occlusion of left pulmonary artery (LPA) flows. Another patient with arterial switch operation had postoperative fibrillatory cardiac arrest, needing resuscitation with internal cardiac massage. The arrest was triggered by coronary ischemia due to periaortic compression. Both instances were caused by hygroscopic nature of Surgicel®, which absorbed blood, swelled, and compressed the luminal tissues.

Tetralogy of Fallot with subarterial ventricular septal defect: Surgical outcome in the current era.

BACKGROUND: Tetralogy of Fallot (TOF) with subarterial ventricular septal defect (VSD) is more common among Asians than Caucasians. Compared with the regular subaortic VSD postoperative right ventricular outflow obstruction is more common because of the sub-pulmonary extension of the defect. The objective of this study is to analyze the surgical implications and outcomes of patients with TOF - subarterial VSD in the current era. PATIENTS AND METHODS: In all, 539 consecutive operated patients with TOF from May 2005 to September 2012 were retrospectively reviewed. Eighty-five patients had subarterial VSD. Seventy-nine of these underwent intracardiac repair. Preoperative clinical, echocardiographic features, operative and postoperative variables were assessed. RESULTS: The median age at surgery was 6 years and the median weight was 14 kilograms. The male to female ratio was 1.7:1. TOF with subarterial VSD was associated with frequent use of transannular patch (74.6%). The early mortality was 2.5%. Follow up was 92% complete with a mean duration of 20 months with actuarial survival of 97.3% at 5 years. Two patients required reoperation for significant right ventricular outflow tract obstruction (RVOTO) at one year and three years, respectively. CONCLUSIONS: Intra cardiac repair for TOF with subarterial VSD has low perioperative mortality and morbidity. Transannular patch augmentation of the right ventricular outflow tract (RVOT) is required in a significant proportion of these patients. Precise suturing of the VSD patch, adequate infundibular resection and lower threshold for a transannular patch placement ensures a smooth early postoperative recovery.
