Intravasation of Pantopaque at myelography is usually related to entry or partial entry of a spinal needle into an epidural vein . This may occur initially, while positioning a spinal needle, or during repuncture for removal of contrast agent. We observed an atraumatic lumbar puncture at the L3-L4 interspace made with a single pass, in which intravasation of contrast material occurred in the mi...

In this issue of the AJNR, Johnson (no relation) et al (page 697) describe their experience with the use of fluoroscopy and epidurography in the placement of epidural steroids. The authors assert that the subarachnoid injection of corticosteroids is a serious complication that can be avoided with the use of epidurography. A series of 5334 outpatient epidural steroid injections were performed af...

Post spinal puncture headache (PSPH) is a well known complication of spinal anesthesia. It occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient's postoperative well being. This manuscript is based on an observational study that runs on Babol University of Medical Sciences and review of literatures about current concepts about t...

BACKGROUND We present a simple technique of arthroscopic rotator cuff repair using a spinal needle and suture loop. METHODS With the arthroscope laterally, a spinal needle looped with PDS is inserted percutaneously into the shoulder posteriorly and penetrated through the healthy posterior cuff tear margin. Anteriorly, another spinal needle loaded with PDS is inserted percutaneously to engage ...

BACKGROUND AND OBJECTIVES Intracranial subdural hematoma is a rare complication following spinal anesthesia. The diagnosis is usually difficult because initial symptoms are the same of post-dural puncture headache. The objective was to report a case of early diagnosed subdural hematoma after spinal anesthesia performed with a fine-gauge needle and single puncture. CASE REPORT 48-year old fema...

The medical procedure is described as follows. First (Fig.1a), (epidural catheter) is inserted into the space between the spinal cord (epidural space in L2-L3 lu first uses a local anesthetic to numb the area where the needle will be inserted. Then the guide needle is inserted and removed, while the catheter remains in place Then (Fig.1b), the propulsion and steering of the magnetic helicoïdal ...

PURPOSE We performed this study to identify the rate and determinants of and associated outcomes with spinal cord infarction among patients treated with aortic stent graft placement at a national level. METHODS We analyzed the data files from Nationwide Inpatient Sample (NIS) from 2002 to 2011. We performed multivariate logistic regression analysis to assess the rates of moderate to severe di...

Transbronchial needle aspiration (TBNA) is a procedure routinely performed to diagnose peripheral pulmonary lesions. However, TBNA is associated with a low diagnostic yield due to inappropriate needle placement. We have developed a flexible transbronchial optical frequency domain imaging (TB-OFDI) catheter that functions as a "smart needle" to confirm the needle placement within the target lesi...

Minimally invasive medical procedures such as biopsies, anesthesia drug injections, and brachytherapy cancer treatments require inserting a needle to a specific target inside soft tissue. This is difficult because needle insertion displaces and deforms the surrounding soft tissue causing the target to move during the procedure. To facilitate physician training and pre-operative planning for the...

BACKGROUND Intramuscular injection of botulinum toxin type-A given by manual intramuscular needle placement in the lower extremity under general anaesthesia is an established treatment and standard of care in managing spasticity in children with spastic cerebral palsy. Optimal needle placement is essential. However, reports of injection and verification techniques used in previous studies have ...
