Article Synopsis
- A 46-year-old woman with headaches and left hemiplegia due to intracranial internal carotid artery (IICA) dissection underwent an emergency STA-MCA bypass after experiencing cerebral hypoperfusion.
- Post-surgery, her symptoms improved, and contrast-enhanced MRI revealed better delineation of the carotid artery over time, supporting her recovery.
- The study emphasizes the effectiveness of STA-MCA bypass in increasing blood flow to the brain and highlights the usefulness of MRI in monitoring disease progression in IICA dissections.
Background: Tarsal tunnel syndrome (TTS) is a common entrapment neuropathy of the posterior tibial nerve. Surgery can be performed less invasively under local anesthesia. We adopted zig-zag skin incision to prevent postoperative wound complications.

Methods: Nineteen consecutive patients with LBP caused by CN-E (superior CN-E = 7; middle CN-E = 12) participated in a Japanese language painDETECT questionnaire survey before surgery.
Identification and decompression of superior cluneal nerve implicated in low back pain.

Article Synopsis
- - Low back pain (LBP) can be linked to the entrapment of the superior cluneal nerve (SCN) near the iliac crest, and a surgical approach can help alleviate the issue, but identifying all entrapped nerves is a challenge.
- - A study with 20 patients (average age 72.5) developed a 3-step surgery procedure to decompress SCNs, discovering a total of 66 nerves across all patients, with varying success at each step.
- - The research concluded that the SCN is most easily identified when the thoracolumbar fascia is first opened; the proposed 3-step method enhances nerve identification during surgery.
Article Synopsis
- Internal carotid artery (ICA) ligation is a surgical technique used to create a high-flow extracranial-intracranial (EC-IC) bypass in patients with aneurysms located in the cavernous portion of the ICA.
- The study reports on four patients who underwent endovascular distal ICA occlusion after the ICA ligation and emphasizes the surgical process, which included using a radial artery graft and detachable coils for occlusion.
- Follow-ups over a mean of 109.5 months showed no aneurysm recurrences, indicating that this procedure is effective and presents a low risk of complications like cerebral infarction.
Mechanical Thrombectomy for Acute Common Carotid Artery Occlusion.
Neurol Med Chir (Tokyo)
February 2023
Mechanical thrombectomy (MT) is the standard treatment for acute large occlusion of the cerebral artery. Evidence for the success of this procedure was based on the treatment of patients with internal carotid artery and middle cerebral artery thrombi. There are a few reports on thrombi extending to the common carotid artery (CCA).

A 58-year-old female with a 2-week headache was diagnosed with left VA dissection. Hemodynamic stress on the right VA detected on 4D flow MRI scans resulted in increased wall shear stress but the vessel was morphologically unchanged.

We focused on the anastomosis between the external carotid artery (ECA) and the RA graft in the cervical region and present adverse events and salvage procedures.
Methods: EC-IC high-flow bypass procedures using an RA graft were performed to treat 87 consecutive patients.
Background: Extracranial carotid artery aneurysms are rare. Surgery may be difficult when vessels are tortuous and on a high cervical level. We report two patients whose tortuous extracranial internal carotid artery (ICA) aneurysm located on a high cervical level was successfully treated by ICA ligation and a high-flow bypass using a radial artery (RA) graft between the external carotid- and the middle cerebral artery.

In addition to digital subtraction angiography (DSA) and 3-dimensional rotational angiography (3DRA), high-resolution cone beam computed tomography (CBCT; especially 80-kv high-resolution cone beam computed tomography) have been performed in recent years. We evaluated the efficacy of CBCT in treating CS dAVF.

To evaluate perioperative and long-term results of CEA in patients with DM, we retrospectively analyzed data of patients with or without DM who underwent CEA in our institute.
Methods: Between January 2005 and December 2010, 281 consecutive CEAs were performed in 268 patients under general anesthesia.
