Case Reports
Successful treatment of post thrombotic syndrome with sequential lumbar sympathetic block.
An underappreciated sequelae of deep venous thrombosis (DVT) is the pain associated with the blood clot in the peripheral extremity. Although most frequently acute in nature, DVT occasionally presents with chronic pain in the affected limb. Furthermore, many individuals suffering from prothrombotic states often have recurring pain from DVT. ⋯ Compression boot/stocking therapy was not combating the discomfort associated with the PTS, often increasing the severity of the patient's pain. Sequential right lumbar sympathetic blocks were performed, which nearly completely resolved the patient's symptoms and improved the patient's ambulatory status and ability to perform activities of daily living. Sympathetic nerve blocks should be considered as a treatment option for patients who suffer with pain from PTS.

Observational Study
Volume of contrast and selectivity for lumbar transforaminal epidural steroid injection.
It has been shown that L4/L5 selective nerve root blocks become nonselective after injecting 1 mL and 0.5 mL of contrast. Volumes of less than 0.5 mL have not been used to determine a volume of definite specificity. ⋯ Diagnostic selective nerve root blocks limiting injectate to a single, ipsilateral segmental level cannot reliably be considered diagnostically selective with volumes as low as 0.2 mL. Also, spread of the contrast to the superior nerve root was more likely than spread to the inferior nerve root.

Inguinal hernia repair is one of the most common operations performed worldwide. Intractable pain following this operation is a potential debilitating complication. The exact etiology of this complex pain is unknown and the treatment of chronic pain after inguinal herniorrhaphy can be a difficult task for both the patient and the clinician. ⋯ This study is a retrospective assessment of a new technique that was applied to a limited number of cases. It remains to be determined whether this technique is superior to the classical open surgical technique in the future. Our findings warrant further studies on the utilization of peripheral nerve stimulation with chronic post herniorrhaphy pain.

The superior hypogastric plexus (SHGP) carries afferents from the viscera of the lower abdomen and pelvis. Neurolytic block of this plexus is used for reducing pain resulting from malignancy in these organs. The ganglion impar (GI) innervats the perineum, distal rectum, anus, distal urethra, vulva, and distal third of the vagina. Different approaches to the ganglion impar neurolysis have been described in the literature. ⋯ A combined neurolytic SHGP block with GI block is an effective and safe technique for reducing pain in cancer patients presented with pelvic and/or perineal pain. Also, a combined SHGP block through a posteromedian transdiscal approach with a GI block through a trans-sacrococcygeal approach may be considered more effective and easier to perform than the recently invented bilateral inferior hypogastric plexus neurolysis through a transsacral approach.
