We describe a case of hemolytic anemia and proximal anastomotic site stenosis following emergency repair of a Type A aortic dissection. This rare complication led to a reoperation to correct the iatrogenic aortic stenosis and cure the consequent hemolysis. A "sandwich" technique (with two Teflon strips on the outside and inside of the aortic wall) was used in the initial repair to reinforce the suture line and prevent bleeding from the aortic anastomoses. At the time of reoperation, the inner Teflon strip at the proximal aortic anastomosis was found to have inverted into the aortic lumen, as suggested by the preoperative magnetic resonance imaging...

Anastomosis between the ophthalmic segment of the internal carotid artery and the A1-A2 junction of the anterior cerebral artery (ACA), described as carotid-ACA anastomosis or infraoptic course of the ACA, is rare and known to demonstrate right-sided predominance. We report a case of bilateral carotid-ACA anastomoses associated with bilateral ophthalmic arteries arising from the sphenoidal branch of the middle meningeal artery that were diagnosed by magnetic resonance (MR) angiography. Identification of rare arterial variations on MR angiography requires careful scrutiny of source images...

We present the case of a 33-year-old man with middle aortic syndrome. The final diagnosis was established with magnetic resonance imaging. He underwent a successful aorto-aortic bypass. Two-year follow-up imaging showed the new graft was patent, with no abnormalities at the anastomosis sites. At the last follow-up examination he was asymptomatic with no neurological dysfunction.

Persistent trigeminal artery (PTA) and its variant (PTAV) are the most prevalent types of carotid-vertebrobasilar anastomosis, but bilateral anastomoses are exceedingly rare. We report a case of a right PTAV and tiny left lateral-type PTA from which the cerebellar artery (presumed anterior inferior cerebellar artery) arose. And also, bilateral ophthalmic arteries arose from the cavernous segments of the internal carotid arteries and entered the orbits via the superior orbital fissures. Selective cerebral angiography, especially 3-dimensional angiography, is superior to magnetic resonance (MR) angiography to identify rare variations of the cerebral arteries...

Primary ureteral fibroepithelial polyps (UFPs) are rare benign tumors of mesodermal origin. The majority UFPs are observed in the proximal part of the ureter and most commonly on the left side. The mean diameter of UFP is reported to be <5 cm. We herein present a rare case of a long primary ureteral polyp originating from the lower ureter in a 53-year-old woman. Following computed tomography, magnetic resonance imaging, retrograde pyelography and ureteroscopic examination, a preliminary diagnosis of giant primary lower ureteral polyp protruding into the bladder was obtained...

Aydin Seref Koksal, Ahmet Tarik Eminler, Erkan Parlak, Ahmet Gurakar
Biliary strictures constitute 40% to 60% of the biliary complications after liver transplantation. They are more common after living donor related liver transplantation (LDLT) than orthotopic liver transplantation (OLT). Balloon dilation followed by multiple plastic stent insertion leads to a mean resolution rate of 84% in the treatment of ASs after OLT. Endoscopic treatment of ASs after LDLT is more difficult because of the small size of the ASs, their multiple number and peripheral location. Balloon dilation followed by multiple plastic stent insertion had a mean resolution rate of 53%...

The Fontan procedure is a common palliative intervention for sufferers of single ventricle congenital heart defects that results in an anastomosis of the venous return to the pulmonary arteries called the total cavopulmonary connection (TCPC). Local TCPC and global Fontan circulation hemodynamics are studied with in vitro circulatory models because of hemodynamic ties to Fontan patient long-term complications. The majority of in vitro studies, to date, employ a rigid TCPC model. Recently, a few studies have incorporated flexible TCPC models, but provide no justification for the model material properties...

Biliary complications are the most common post-liver transplant (LT) complications with an incidence of 15%-45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT (LDLT) compared to a deceased-donor LT (DDLT). Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%...

Tetralogy of Fallot (TOF) can be associated with vascular malformations or variations, especially of the aortic arch or supracardiac major venous systems. We report its association with an extremely rare combination of three such variations of the cerebral arteries-a right persistent hypoglossal artery, an extremely rare left carotid-right anterior cerebral artery (ACA) anastomosis, and a left accessory middle cerebral artery arising from the A1-A2 junction of the left ACA-which were diagnosed by magnetic resonance angiography in a 9-year-old girl during evaluation of multiple acute cerebral infarctions...

A 63-year-old man presented at our hospital with right upper abdomen pain and fever for 4 d. The patient's magnetic resonance cholangiopancreatography revealed dilated common bile duct and choledocholithiasis. In his past history, he received proximal gastrectomy and modified double tracks anastomosis. Endoscopic retrograde cholangiopancretography in modified double tracks anastomosis, especially accompanied with anastomotic stenosis, has been rarely reported. In the present case, the duodenoscope was successfully introduced over the guidewire and the stone taken out using a basket...

We are reporting the case of a 32-year-old female who had suffered from fecal incontinence (FI). She was born with an imperforate anus and a recto-vaginal fistula; she underwent repair at 6 mo of age. At 29 years of age, she was still fecally incontinent despite extensive pelvic floor reeducation. A magnetic resonance imaging and an anal electromyography were performed. Because her symptoms were considered to be probably due to extra-sphincteric implantation of the neo-anus, a redo was performed of the recto-neo-anal intra-sphincteric anastomosis...

BACKGROUND: Accurate diagnosis of Crohn's disease or ulcerative colitis is essential for surgical planning. This study compared the accuracy, safety, and utility of small bowel follow-through (SBFT) and magnetic resonance enterography (MRE) for detecting small bowel (SB) involvement preoperatively. METHODS: A retrospective review of children who underwent colectomy for inflammatory bowel disease (2000-2014) was performed. Preoperative SBFT and MRE were independently reviewed by two radiologists blinded to clinical data...

OBJECTIVE: Numerous surgical approaches regarding aortic arch advancement for neonatal arch hypoplasia have been described. These repairs can be classified into two categories: those that incorporate a patch and those that do not. The decision between repairs remains largely experiential, rather than empirical, because of the limited number of reported outcomes. We report early outcomes from neonates undergoing modified aortic arch advancement with an anterior patch and our experience using computational fluid dynamic modeling to better understand the hemodynamic consequences associated with this repair...

OBJECT: Microsurgical anastomosis from the superficial temporal artery (STA) to the middle cerebral artery (MCA) is a treatment option for appropriately selected patients with cranial atherosclerotic steno-occlusive disease (CASD). However, the long-term efficacy and patency of the donor artery remain unclear. We reviewed the signal intensity of the donor artery on magnetic resonance angiography (MRA) after STA-MCA anastomosis in patients with CASD and clarified the incidence of and risk factors for reduction in postoperative signal of STA...

BACKGROUND & AIMS: Nonrelaxing pelvic floor dysfunction (N-RPFD), or dyssynergic defecation, is the paradoxical contraction and/or impaired relaxation of pelvic floor and anal muscles during defecation. Few studies have evaluated this disorder in patients with an ileal pouch-anal anastomosis (IPAA). We investigated the frequency of N-RPFD in patients with and without chronic pouchitis following IPAA and the effectiveness of biofeedback therapy within this population. METHODS: We conducted a retrospective study of all patients with an IPAA who underwent anorectal manometry between January 2000 and March 2015 (n = 111)...

Perioperative compression neuropathy is a known potential complication of prolonged surgical procedures. Sciatic postoperative neuropathy has rarely been reported. We present a 34-year-old woman who underwent right breast reconstruction with supercharged (venous anastomosis) transverse rectus abdominis flap and developed bilateral sciatic compression neuropathy. Her history was remarkable for sleeve gastrectomy 2 years earlier resulting in 105 pound weight loss 1 year before breast reconstruction. During the procedure, the patient was in the supine position for 8 hours and in the semirecumbent position for an additional 2 hours with the torso flexed at 30 degrees and knees flexed at approximately 45 degrees in addition to standard padding...
