Arterial spin labeling imaging correlates with the angiographic and clinical vascularity of vestibular schwannomas

We examined whether HVSs can be predicted by using arterial spin labeling (ASL) imaging.MethodsA total of 103 patients with VSs underwent ASL imaging and digital subtraction angiography (DSA) before surgery. Regional cerebral blood flow (CBF) of gray matter and regional tumor blood flow (TBF) were calculated from ASL imaging, and we defined the ratio of TBF to CBF as the relative TBF (rTBF = TBF/CBF). Angiographic vascularity was evaluated by DSA, and clinical vascularity was evaluated by the degree of intraoperative tumor bleeding. Based on the angiographic and clinical vascularity, the VSs were divided into two categories: HVS and non-HVS. We compared rTBF with angiographic and clinical vascularities, retrospectively.ResultsThe mean rTBFs of angiographic non-HVSs and HVSs were 1.29 and 2.58, respectively (p

ConclusionsTime to AE did not improve. Patients referred from CT are physiologically different from CS and should be analyzed accordingly, with CS resulting in faster time to AE in sicker patients. Contemporary resuscitation challenges the need for hyperacute AE as no patients exsanguinated despite time to AE of more than 2  h.

Rationale: Although surgery has been the standard treatment for pancreaticoduodenal trauma because of the complex anatomical relation of the affect organs, transcatheter arterial embolization (TAE) has recently been introduced as a safe and effective treatment. However, TAE for pancreaticoduodenal arterial hemorrhage (PDAH) can be challenging because it is difficult to localize the involved artery and to embolize the bleeding completely due to the abundant collateral channels of the pancreaticoduodenal artery (PDA). Patient concerns: Herein, we report 2 cases of PDAH that occurred after falling down in case 1 and a pe...

Conclusions: This underpowered study, when considered together with previous clinical trials, does not support early coronary angiography for comatose survivors of cardiac arrest without ST elevation. Whether early detection of occluded potential culprit arteries leads to interventions that improve outcomes requires additional study.

Abstract BACKGROUND: Ocular ischemic syndrome is a rare disease, which must be considered as a differential diagnosis in cases of painful loss of vision. CASE REPORT: A 63-year-old male patient presented as an emergency in our consultation with hyphemia and decompensated intraocular pressure of the right eye. The right eye had been painful for 3 weeks. Apart from nicotine abuse, no relevant pre-existing medical conditions were known. With suspected iritis, the initial treatment was performed with eye drops containing a corticosteroid. After initial improvement in symptoms, an acute deterioration occ...

In conclusion, a variety of embolization techniques may be applied for the treatment of pseudoaneurysm after PD, which have high technical and clinical success rates and small trauma. It is recommended in emergency situations, but care should be taken to avoid serious technical complications. PMID: 32952628 [PubMed]

We present three cases of colonic ischemia that can be attributed to the hypercoagulable state related with SARS-CoV2 and disseminated intravascular coagulation. Three males aged 76, 68 and 56 with respiratory distress presented episodes of rectal bleeding, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia. One patient (case 2) in which a computed tomography (CT) scan showed perforation of the gangrenous cecum underwent surgery. D-dimer levels were markedly increased (2,170, 2,100 and 7,360 ng/ml) in all three patients. All three patien...

Conclusions: Both 3D image reconstruction and thin-section MDCT provided precise preoperative information about SA. The 3D image reconstruction software "Exoview" could visualize SA for surgeons. However, the thin-section MDCT provided a better evaluation of small SA branches. PMID: 32944331 [PubMed]
