Case Reports
Anaphylactic Shock followed by Indocyanine Green Videoangiography in Cerebrovascular Surgery.
Indocyanine green (ICG) video angiography has been widely used in cerebrovascular surgery. ICG injection is generally safe, with a low incidence of complications. ICG-related anaphylactic reactions during neurosurgery have been rarely reported. We report the cases of 2 patients who had experienced anaphylactic shock in response to intravenous ICG injection (DID Indocyanine Green [Dongindang, Inc., Gyeonggi-do, Republic of Korea]) during intracranial aneurysm (IA) surgery. ⋯ Despite the rarity of ICG-related anaphylaxis, clinicians should be aware of this unexpected, but potentially life-threatening, drug reaction in patients undergoing cerebrovascular surgery.

Spinal dural arteriovenous fistulas (DAVFs) in the sacral region are extremely rare. The location and complex angioarchitecture of these lesions make both identification and treatment challenging, even in experienced hands. We report on a sacral DAVF with a unique angioarchitecture and discuss its specific anatomy. ⋯ Sacral DAVFs present serious diagnostic difficulties and require a profound understanding of possible fistula-supplying arteries of the sacral region. Microsurgical interruption of the often ventrally located drainage vein presents an efficient treatment modality and could provide an immediate confirmation of fistula occlusion using indocyanine green videoangiography.

Observational Study
SBRS "Surgical Back Risk Syndrome" and Spinal Cord Stimulation: It's better safe than sorry.
Recurrent and chronic low back pain, caused by degenerative lumbar spondylosis, commonly affects elderly patients, even those with no previous low back surgery. These patients, like those affected by failed back surgery syndrome (FBSS), may become unresponsive to medical conservative treatment and their quality of life could be easily compromised. Moreover, general comorbidities, obesity, and other typical conditions of the elderly may make surgery under general anesthesia riskier than the natural history of the disease. These patients could be considered affected by surgical back risk syndrome (SBRS). ⋯ In our opinion, SCS could be considered as a valid alternative treatment not only in selected patients affected by FBSS but also in selected patients affected by SBRS, in whom back surgery under general anesthesia may be challenging and overcome the potential benefit of the surgery itself. SBRS could be considered a new disease entity to be managed through SCS.

The most uncontrollable complication during coil embolization of a ruptured cerebral aneurysm is thromboembolic ischemia. We analyzed whether thromboembolic complications could be reduced by using preoperative antiplatelet medications for acute subarachnoid hemorrhage in multicenter fashion. ⋯ Preoperative multiple antiplatelet medication reduced thromboembolic events in coiling during acute stage subarachnoid hemorrhage and improved clinical outcomes.

Distal ophthalmic artery (OpA) aneurysms are a rare subset of vascular lesions with lack of optimal treatment. The management of these aneurysms may require complete occlusion of the parent vessel, carrying a risk of permanent visual impairment due to individual variations of extracranial collateral flow to the intraorbital ophthalmic artery (iOpA). ⋯ This study demonstrates the feasibility of a novel revascularization technique of the iOpA using 2 different transorbital approaches. These techniques can be used in the management of intraorbital lesions such as OpA aneurysms, tumoral infiltrations, or intraoperative injuries.
