Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed...

AIM: To identify factors predicting outcome of endoscopic therapy in bile duct strictures (BDS) post living donor liver transplantation (LDLT). METHODS: Patients referred with BDS post LDLT, were retrospectively studied. Patient demographics, symptoms (Pruritus, Jaundice, cholangitis), intra-op variables (cold ischemia time, blood transfusions, number of ducts used, etc.), peri-op complications [hepatic artery thrombosis (HAT), bile leak, infections], stricture morphology (length, donor and recipient duct diameters) and relevant laboratory data both pre- and post-endotherapy were studied...

OBJECTIVES: Open heart surgery for interrupted aortic arch in the neonatal period is still a high-risk procedure related in part to patient factors such as low birth weight, other morphologic anomalies, and, especially, small aortic valve size. Recently, we performed hybrid palliation with bilateral pulmonary artery banding and ductal stenting as the first-stage palliation for such cases. In this study, the outcomes of this procedure were examined. METHODS: Six cases of interrupted aortic arch with a small aortic valve underwent the hybrid procedure in the neonatal period in our institute from 2010 to 2015 (mean age: 6...

A newborn with tricuspid atresia and pulmonary atresia underwent ductal stenting. The aortic end of the ductus was not completely covered and was wide open; the baby was discharged on dual antiplatelets. The baby presented after a month with desaturation, and an angiogram showed extensive thrombus in the stent and the right pulmonary artery. The angle formed by the stent with the uncovered aortic end is likely to have precipitated the thrombus.

We report a case of combined hepatocellular-cholangiocarcinoma with stem cell features, cholangiolocellular subtype arising about 15 years after placement of an inferior vena cava stent for primary Budd-Chiari syndrome. Pre-surgical differentiation of the tumor from hepatocellular carcinoma was difficult because of elevated levels of alpha-fetoprotein and hypervascularity in the arterial phase. Histopathological examination revealed atypical cells forming ductal and alveolar structures showing a vague border with the surrounding liver...

OBJECTIVE: To determine the short- and medium-term outcomes of ductal stenting (DS) in patients with functionally univentricular hearts (FUHs) and ductal-dependent pulmonary blood flow. BACKGROUND: Several studies have evaluated the outcomes of DS in a limited number of patients with FUHs. Nonetheless, there is still no consensus regarding the indications for this procedure, and no appropriate patient selection criteria have been devised. METHODS: From 2005 to 2015, cardiac catheterization for DS was performed in 68 patients with FUHs...

Irreversible electroporation (IRE) is a non-thermal ablation technique used especially in locally advanced pancreatic carcinomas that are considered surgically unresectable. We present the first case of acute superior mesenteric artery (SMA) occlusion secondary to pancreatic IRE procedure that has not been reported before in the literature. A 66-year-old man underwent neoadjuvant chemoradiotherapy for locally advanced pancreatic ductal adenocarcinoma. IRE procedure was applied to the patient during laparotomy under general anesthesia...

OBJECTIVES: We aimed to study the feasibility and outcomes of ductal stenting in patients with duct-dependent pulmonary blood flow (PBF). METHODS: Duct-dependent hypoxic patients with confluent pulmonary artery (PA) branches were enrolled for ductal stenting and followed regularly. RESULTS: Sixty patients, with a median age of 12 (1-1095) days and weight of 2.8 (2.2-8.9) kg, were enrolled. Median right PA (RPA) and left PA (LPA) Z-scores were -1...

We report interventional re-opening of a PDA for reverse Potts shunt circulation 12 months after closure in a 3.8 year old child, suffering from right ventricular (RV) failure due to suprasystemic pulmonary artery hypertension (PAH) after ADO I implantation. After ex vivo simulation, perforation through the mesh of the ADO I with the use of transseptal needle, wire looping (AO-PA), balloon dilatation, stent implantation (Palmaz 6 mm) and post dilatation, a reverse Pott-shunt circulation was established. A follow-up period of 11 months was achieved with preserved RV function and reverse Pott shunt circulation maintained a post ductal saturation of 94-88%...

The spleen and pancreas are at risk for injury during abdominal trauma. The spleen is more commonly injured because of its fragile structure and its position immediately beneath the ribs. Injury to the more deeply placed pancreas is classically characterized by discordance between the severity of pancreatic injury and its initial clinical expression. For the patient who presents with hemorrhagic shock and ultrasound evidence of major hemoperitoneum, urgent "damage control" laparotomy is essential; if splenic injury is the cause, prompt "hemostatic" splenectomy should be performed...

Hepatic arterial flow is paramount in preserving biliary integrity. We present an interesting clinical scenario of a liver transplant recipient with biliary anastomotic stricture who developed biliary abscess and sepsis after Endoscopic Retrograde Cholangiopancreatography. The abscess did not respond to maximal medical management, percutaneous drainage, and adequate endoscopic biliary drainage. Clinically, patient continued to deteriorate and imaging identified hepatic artery stenosis which was treated with percutaneous intra-arterial stenting...

A 53-year-old woman underwent breast-conserving surgery for right breast cancer (invasive ductal carcinoma, T1cN0M0, ly+, stage ⅠA, ER+, PR+, HER2-) 5 years previously. During treatment with tamoxifen, massive recurrence in the axillary lymph nodes was found. First- through fourth-line chemotherapy were tried, but they all failed. Everolimus and exemestane were administered, resulting in rapid shrinking of the tumor, but the patient developed sudden severe bleeding from the subclavian artery. Hemostasis was achieved with artery stenting...

BACKGROUND: Carotid artery access in infants with congenital heart disease undergoing cardiac catheterization via a surgical cut down has been well described. There is a paucity of information regarding percutaneous carotid artery (CA) access in infants <3 months. METHODS: A retrospective review of infants <3 months of age undergoing cardiac catheterization via percutaneous CA approach was performed after IRB approval. Between January 2012 and May 2015, 18 patients underwent 20 procedures; median age 13 days (2-77); median weight 3...

The hybrid approach to management of hypoplastic left heart syndrome (HLHS) was developed as an alternative to neonatal Norwood surgery, providing a less invasive initial palliation for HLHS. We describe our experience in extending the concept of the hybrid procedure to palliate neonates with anatomically compromised systemic arterial blood flow in a variety of congenital cardiac anomalies and supporting its application as first-line palliation in centers developing their HLHS programs. Retrospective review of patients undergoing therapy for HLHS at a single institution from June 2008 to December 2014 was performed...

BACKGROUND: Hybrid procedure offers patients with severe congenital heart disease an alternative initial procedure to conventional surgical reconstruction. We report the midterm outcomes of a cohort of neonates who had a hybrid procedure for variants of hypoplastic left heart syndrome because they were at high risk for the Norwood procedure. METHODS: Between December 2005 and January 2013, 41 neonates underwent bilateral pulmonary artery banding followed by ductal stenting by means of a sternotomy at a median age of 6 days (range, 2 to 18 days) and weight of 2...

For high-risk neonates with hypoplastic left heart syndrome (HLHS) undergoing Norwood operation, the strategy of bilateral pulmonary artery banding and ductal stenting is risky in case of coarctation of the aorta (CoA), often resulting in death. Therefore, we devised a new method of ductal stenting with side-branch cell dilation, which could overcome the constriction of the ductal arch with CoA in two HLHS patients. This is the first report that presents this method and the results. © 2015 Wiley Periodicals, Inc...

BACKGROUND: Results of surgical management of hypoplastic left heart syndrome (HLHS) and related anomalies are often compared to published benchmark data which reflect the use of a variety of surgical and hybrid protocols. We report encouraging results achieved in an emerging program, despite a learning curve at all care levels. Rather than relying on a single preferred protocol, surgical management was based on matching surgical strategy to individual patient factors. METHODS: From 2010 to 2014, a total of 47 consecutive patients with HLHS or related anomalies with ductal-dependent systemic circulation underwent initial surgical palliation, including 30 Norwood stage I, 8 hybrid stage I, and 9 salvage-to-Norwood procedures...

Stenting of patent ductus arteriosus is an alternative to palliative cardiac surgery in newborns with duct-dependent or decreased pulmonary circulation; however, the use of this technique in patients with an aortic arch abnormality presents a challenge. Tetralogy of Fallot is a congenital heart defect that is frequently associated with anomalies of the aortic arch and its branches. The association is even more common in patients with chromosome 22q11 deletion. We present the case of an 18-day-old male infant who had cyanosis and a heart murmur...

Complex cases undergo step surgical and percutaneous procedures, including stent deployment. Concerns arise on stent removal at latest surgery. Our initial experience is presented. Forty-six stents in 35 patients were partially or totally removed at surgery. Univentricular heart was diagnosed in 20 patients. Stents were previously deployed in: ductus (6), right ventricle outflow tract (12), atrial septal defect (4), right pulmonary artery (4), left pulmonary artery (16), inferior vena cava (2), superior vena cava (1) and ascending aorta (1)...
