The iliolumbar artery,Anatomic considerations and details on the common iliac artery trifurcation

CLINICAL ANATOMY, Issue 1 2010
M.C. Rusu
Abstract The iliolumbar artery (ILA) of Haller is the largest nutrient pedicle of the ilium and its detailed knowledge is important for various surgical procedures that approach the lumbosacral junction, the L4/L5 disk space, the sacroiliac joint, the iliac and psoas muscles, or the lumbar spine. Also the ILA is relevant for various techniques of embolization. We aimed to evaluate the anatomic and topographic features of the ILA, by dissection on 30 human adult pelvic halves and on 50 angiograms. ILA was a constant presence and it emerged at Level A (from the common iliac artery (CIA), 8.75%), Level B (from the CIA bifurcation, 2.5%), Level C (from the internal iliac artery (IIA), 52.5%), Level D (from the IIA bifurcation, 3.75%), and Level E (from the posterior trunk of the IIA, 32.5%). Level B of origin of the ILA corresponds to a trifurcated CIA (morphology previously unreported), while Level D corresponds to a trifurcated IIA. A higher origin of the ILA corresponds to a more transversal course of it. A descending lumbar branch that leaves the iliac arterial system independently to enter the psoas major muscle, as seen in 48% of cases, may be misdiagnosed as ILA. Surgical interventions in the lumbar, sacral, and pelvic regions must take into account the variable origins of the ILA from the iliac system that can modify the expected topographical relations and may lead to undesired hemorrhagic accidents.

Maxillary Sinus Elevation Surgery: An Overview

JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 5 2003
ELIAZ KAUFMAN DDS
ABSTRACT Maxillary sinus elevation surgery was developed to increase the height of bone available for implant placement in the posterior maxilla. The efficacy and predictability of this procedure have been determined in numerous studies. The basic approach to the sinus (Caldwell-Luc operation) involves an osteotomy performed on the lateral maxillary wall, elevation of the sinus membrane, and placement of bone graft material. The graft materials can be categorized into four groups: autogenous bone, allografts (harvested from human cadavers), alloplasts (synthetic materials), and xenografts (grafts from a nonhuman species). These graft materials can be used alone or in combination with each other. Implant placement can occur at the same surgical procedure (immediate placement) or following a healing period of 6 to 9 months (delayed placement). A more conservative approach to the sinus, the osteotome technique, has been described as well. CLINICAL SIGNIFICANCE This article provides an overview of the surgical technique, with emphasis on anatomic considerations, preoperative patient evaluation (clinical and radiographic), indications and contraindications to the procedure, and possible risks and complications.

Device Extraction in Adults with Congenital Heart Disease

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 3 2009
DAVID CESARIO M.D., Ph.D.
Background: Device extraction is a critical component in the treatment of patients with device-related infections. Due to complex anatomic considerations, device extraction in adults with congenital heart disease presents unique challenges to the electrophysiologist. Methods: Here, we present a series of device-extraction cases performed in patients with transposition of the great arteries status post either Mustard or Senning surgical procedures that subsequently had permanent pacemakers placed and ultimately developed device-related infections. Results: All of these patients eventually underwent successful laser extractions of their infected devices resulting in complete removal of all hardware and resolution of their infections. Conclusions: These cases illustrate that endovascular device extraction has been safely and effectively performed in adult patients with congenital heart disease, though further studies are needed to determine the procedural risks and success rates of this procedure in this patient population.
