The epidural space is frequently used for placement of the epidural needle, catheter, and various pharmacological agents. The presence of structures in the epidural space such as epidural fat, venous plexus, or ligaments that may lead to uneven distribution of agents within the epidural space have been described.(1-3) Whether these structures are anatomical (such as connective tissue) or functional (due to distortions of actual anatomy secondary to injection of agents epidurally) has been disputed.(2-5) We describe our management of a patient who presented with bilateral radicular symptoms and severe low back pain...

REVIEW
Marc J Dinkin, Athos Patsalides
Idiopathic intracranial hypertension causes headache, papilledema and visual field loss, typically in obese women of childbearing age. Its anatomical underpinnings remain unclear, but a stenosis at the junction of the transverse and sigmoid sinuses has been recognized in the majority of patients through venography. The stenosis may result from intrinsic dural sinus anatomy or extrinsic compression by increased intracranial pressure, but in either case, its stenting has been shown to lead to an improvement in symptoms of intracranial hypertension and papilledema in multiple retrospective, non-controlled studies...

AIM: Surgical treatment is still the cornerstone in the treatment of breast cancer, a very common neoplasia, particularly affecting the female elderly population. Axillary dissection is crucial in the treatment of some tumours, but variations in axillary vessels anatomy are poorly described in standard anatomy and surgical textbook. We aimed to describe anatomical variations in axillary vessels found in our institutional experience. PATIENTS AND METHODS: A prospective 3-year study was conducted in our institution from January 2012 to December 2014...

OBJECTIVES: Although the postnatal physiology of D-loop transposition of the great arteries with intact ventricular septum (DTGA-IVS) is well established, little is known about fetal DTGA-IVS. In the normal fetus, the pulmonary valve (PV) is larger than the aortic valve (AoV), there is exclusive right to left flow at the foramen ovale (FO) and ductus arteriosus (DA), and the left ventricle (LV) ejects 40% of combined ventricular output (CVO) through the aorta, primarily to the brain. In DTGA-IVS, the LV ejects O2 -rich blood to the pulmonary artery, theoretically leading to pulmonary vasodilation, increased branch pulmonary arterial flow and reduced DA flow...

Abernethy malformation, also known as congenital extrahepatic portosystemic shunts (CEPS) is a rare clinical entity and manifests with different clinical symptoms. CEPS are abnormalities of vascular development where there is shunting of portal blood into the systemic venous system. Multidetector computed tomography (MDCT) is a fast and effective modality for evaluation of CEPS. CT displays all the information desired by the surgeon as well as the clinician including the anatomy of the splenic and superior mesenteric veins, size and site of the shunt, presence or absence of the portal vein radicles, and helps to plan the therapy and even the follow-up of these patients...

INTRODUCTION: A lack of information about the feasibility and safety of leadless pacemaker (LPMs) exists in a fragile population of patients with limited venous anatomy access or conventional pacemaker (PM) contraindication. Accordingly, the goal of this prospective observational study was to report our experience with this new leadless technology in a subset of patients with contraindication or limited venous access. METHODS AND RESULTS: Between May 2015 and July 2016, 14 patients were consecutively included...

BACKGROUND: For radiologists, the venous drainage of adrenal glands is a key to the technique of selective adrenal venous sampling. For endocrine surgeons, it is key to adrenalectomy for carcinoma and pheochromocytoma. This study aims to demonstrate direct anastomosis between the left adrenal vein, the diaphragmatic circulation and the azygos system. Anatomical textbooks only offer very little information concerning the left adrenal vein (LAV) and its potential anastomosis with the reno-lumbo-azygo trunk (RLAT) and the diaphragmatic circulation...

Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses challenges to surgeons and increases the risk of bleeding during organ removal. Accompanying vascular variations can cause unexpected bleeding and injury and therefore technical complications in procurement and subsequent implantation...

BACKGROUNDS: Various flaps elevated from the palm have been widely used for finger and hand reconstruction. Recently, perforator-based free flaps or venous free flaps have received popularity due to several advantages. The cutaneous venous system has been chosen as the circulatory outlet when designing and harvesting the flap from the palmer area due to the small size and thin nature of the flap. However, there have been few descriptions about the anatomy of the palmar cutaneous veins...

OBJECTIVE: To determine predictors of poor outcome in patients with heterotaxy syndrome. METHODS: A retrospective review of children with heterotaxy syndrome, in a single tertiary paediatric cardiology centre, was conducted between 1 January 1997 and 1 January 2014 to determine predictors of poor outcome. Poor outcome was defined as death, cardiac transplantation or New York Heart Association (NYHA) functional class III or IV. RESULTS: There were 35 patients diagnosed with heterotaxy syndrome, 17 of whom were diagnosed antenatally...

REVIEW
Matthew D Files, Brian Morray
Total anomalous pulmonary venous connection refers to a spectrum of cardiac anomalies where the pulmonary veins fail to return to the left atrium and the pulmonary venous blood returns through a systemic vein or directly to the right atrium. There is a wide anatomical variety of venous connections and degrees of pulmonary venous obstruction that affect the presentation, surgical repair, and outcomes. In this review, we explore the preoperative physiology, echocardiographic diagnosis, and approach to postoperative complications...

INTRODUCTION: We used an approach different from traditional anatomy to construct a three-dimensional (3D) model of the corona mortis (CMOR) through contrast-enhanced computed tomography (CT) scanning. This will provide an aid for the understanding of the fine anatomy of the CMOR, as well as surgical procedures. MATERIAL AND METHODS: A medical image processing system was used to process computed tomography scanning data collected from 330 cases of female patients...

BACKGROUND: Surgical resection is the only cure for hepatopancreatobiliary (HPB) malignancy. In the era of multidisciplinary approaches and neoadjuvant therapies for locally advanced, borderline resectable tumors, the feasibility and efficacy of en bloc vascular resection has been validated across multiple studies. However, the variability of venous anatomy within the perihepatic and peri-portal regions necessitates familiarity with alternative resection and reconstruction techniques appropriate to the specific region of tumor invasion...

Eleonora Tricarico, Francesco Tricarico, Carlo Florio
The evaluation of pulmonary veins during cross-sectional imaging of the chest and the knowledge of their embryology and anatomy are useful for detecting congenital conditions that may be clinically significant. Moreover, with the spread of cross-sectional imaging it is very frequent to find anatomical variants; therefore the radiologist should easily recognize their appearances. This case report shows a left-side upper partial anomalous pulmonary venous return (PAPVR) through a "curved" vein that joins the left brachiocephalic vein, in a female patient who underwent whole-body computed tomography (CT) for staging endometrial cancer...

Abdel Rahman Al Emam, Ahmed Abuzaid, Mohammad Chamsi Pasha
Persistent left superior vena cava (PLSVC) is encountered occasionally during angiographic procedures. It usually coexists with right superior vena cava and drains to the right atrium through the coronary sinus, but multiple variations are described. Although PLSVC is extensively reported in the literature, there are very few articles addressing right heart catheterization in patients with isolated PLSVC. We present a patient with absent right superior vena cava and PLSVC draining to a dilated coronary sinus diagnosed during right heart catheterization in the setting of pulmonary hypertension...

The primary extracardiac inferior cavopulmonary connection is an unusual novel palliation for single-ventricle physiology, which we first performed in the setting of unfavourable upper-body systemic venous anatomy for a standard bi-directional Glenn, and in lieu of leaving our patient with shunt-dependent physiology. After an initial 16-month satisfactory follow-up, increasing cyanosis led to the discovery of a veno-venous collateral that was coiled, but, more importantly, to impressive growth of a previously diminutive superior caval vein, which allowed us to perform completion Fontan with a good outcome...
