PURPOSE: Optimal perfusion of the gastric conduit during esophagectomy is elementary for the anastomotic healing since poor perfusion has been associated with increased morbidity due to anastomotic leaks. Until recently surgical experience was the main tool to assess the perfusion of the anastomosis. We hypothesized that anastomoses located in the zone of optimal ICG perfusion of the gastric conduit ("optizone") have a reduced anastomotic leakage rate after esophagectomy. METHODS: Indocyanine green (ICG) fluorescence tissue angiography was used to evaluate the anastomotic perfusion in 35 patients undergoing esophagectomy with gastric conduit reconstruction...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

The cephalic vein arises from the radial end of the dorsal venous arch. It turns around the radial border of the forearm and passes proximally along the arm to the shoulder, where it enters the axillary vein by penetrating the clavipectoral triangle. The cephalic vein is prone to vary at the antecubital fossa, where it forms numerous anastomoses. A male cadaver fixated with a 10% formalin solution was dissected during regular anatomy lessons. It was found that the cephalic vein crossed the upper third of the arm between two fasciculi of the deltoid muscle and reached the shoulder, where it passed above the acromion and crossed the posterior border of the clavicle in order to join the external jugular vein...

REVIEW
Valeriy Shubinets, River M Elliott
The thumb ulnar pulp is a critical component of key pinch and precision manipulation. Injuries to this area should be reconstructed with robust, sensate tissue that restores bulk and contour. The existing reconstructive options, however, have substantial risks and drawbacks. We describe an anterograde homodigital neurovascular island flap that provides both sensate and durable coverage of the ulnar thumb pulp. The flap uses innervated glabrous tissue, limits donor site morbidity to the thumb and first web space, and does not require microvascular anastomoses or nerve coaptation...

OBJECTIVE: Microvascular coupler devices have been proven an effective alternative to standard hand-sutured anastomoses in reconstructive surgery. Until now, the influence of the coupler size on the revision rate after free flap tissue transfer in head and neck surgery has not been investigated. Neither has its influence on the timing of venous revisions. MATERIALS AND METHODS: A retrospective mono-center cohort study was performed in order to analyze the influence of coupler size on timing and revision rate of microvascular procedures...

EDITORIAL
Hugh S Paterson, Paul G Bannon
The use of composite coronary artery bypass grafts from the left internal mammary artery (LIMA) has increased over the last 20 years. Total arterial revascularisation can be achieved with two arterial conduits and is associated with a reduced risk of stroke. However, the traditional coronary bypass graft configurations of the in situ LIMA and aorto-coronary saphenous vein grafts remain as the mainstay of coronary bypass surgery in most centres. Concerns regarding composite Y grafts relate to (1) the adequacy of a single inflow for all coronary bypass grafts; (2) the risk of compromising the LIMA flow to the left anterior descending coronary artery; (3) the effects of competitive flow on graft patency; and (4) the use of sequential coronary anastomoses...

PURPOSE: The safety and effectiveness of a stapled intestinal anastomosis in adults, children, and infants is well documented. However, in neonates it is not well validated. We hypothesized that premature infants who received a stapled bowel anastomosis utilizing endoscopic staplers had similar outcomes compared to patients with a handsewn anastomosis. METHODS: A retrospective study was performed reviewing premature infants who underwent an intestinal anastomosis over a 4-year period...

We describe a novel intracranial-to-intracranial bypass technique between the anterior temporal artery and the posterior cerebral artery for revascularization of the posterior circulation. Four formalin-fixed human heads were examined to demonstrate the detailed anatomy of the middle cerebral artery and the posterior cerebral artery, and to illustrate the step-by-step bypass procedure. The anterior temporal artery, a branch of the middle cerebral artery, can be anastomosed to the P2 segment of the posterior cerebral artery as an alternative to extracranial bypass donor segments for treatment of complex aneurysms requiring revascularization...

BACKGROUND: In a vessel-depleted neck, distant recipient sites may be the only option for secondary free flap reconstruction. While interposition vein grafts and arteriovenous loops can bridge the gap between the recipient and donor pedicle, they are not without risks. In these scenarios, we examinate the reliablity of a radial forearm free flap (RFFF) as an alternative vascular conduit. PATIENTS AND METHODS: A retrospective review of cases between March 2005 and May 2016 was performed...

OBJECTIVE: Ileal transposition (IT) procedure leads to higher secretion of incretin hormones what is associated with a beneficial metabolic effect. However, IT will also have an influence on the related jejunum and ileum function. The aim of this research was to investigate the morphology of the jejunum and transposed ileum with the use of light and transmission electron microscopy (TEM) in order to determine the local alternations in the intestine resulting from the transposition. METHODS: Twenty male, 8-week-old, obese Zucker rats underwent IT and six of them sham surgery...

Anastomotic leakage is more frequently reported in colonic anastomoses. Ischemia reperfusion injury is one of the main reasons for anastomotic leakage. Simvastatin is known to prevent tissue damage induced by free oxygen radicals after ischemia reperfusion injury. The effect of simvastatin on colonic anastomosis impaired by ischemia reperfusion injury is investigated. Single layer, end-to-end colocolic anastomosis after 0.5-cm colon resection was performed in Wistar Albino rats. In Group 1 (control) (n = 10), colonic anastomosis without I-R was performed...

BACKGROUND: For patients with severe ischemic heart disease, complete revascularization by a percutaneous coronary intervention or coronary artery bypass grafting is often not achieved and may still cause residual angina. In case of progressive coronary artery occlusions, therapeutic arteriogenesis constitutes a promising strategy for increasing blood supply to the ischemic myocardium. Whether the formation of collaterals in the hypofused myocardium is angiogenetic in nature or based on preformed coronary artery anastomoses remains debatable...

BACKGROUND AND AIMS: Extended left hemicolectomy might be necessary for several indications. Once the resection is completed, it would be difficult or impossible to anastomose the transverse colon to the rectum due to the difficulty in mobilizing the transverse colon to reach for a tension-free rectal anastomosis. The aim of this report is to present the "Flip-Flop" technique to overcome this challenging situation. The procedure is based on a surgical technique published in the early 1960s to avoid permanent stoma after proctectomy and consists of changing the location of the right colon to reach the rectum...

Pulmonary artery anastomosis stenosis is a rare cause of right ventricular failure after orthotopic heart transplantation. In this case report, direct ultrasound of the pulmonary artery helped diagnose stenosis at a location not visible on transesophageal echocardiography or even with standard epicardial ultrasound views. It is important to evaluate all vascular anastomoses after heart or lung transplantation because surgical revision of these lesions is facile, but if left undiagnosed, significant morbidity or mortality is likely...
