The effect of induced hypertension (iHTN) on functional outcomes in noncardioembolic acute ischemic stroke (AIS) with early neurological deterioration remains unclear. We performed a systematic review and meta-analysis evaluating the safety and efficacy of iHTN vs medical management. A literature search of PubMed/MEDLINE, Web of Science, Ovid Embase, and Scopus from inception through November 6th, 2025. The protocol was registered in PROSPERO (CRD420261282211). Studies evaluating iHTN within 72 h of AIS onset and reporting 90-day functional independence (modified Rankin Scale [mRS] 0-2) were included. Safety outcome was hemorrhagic transformation. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were estimated using random-effects model based on Restricted Maximum-Likelihood (REML) methods. Three studies were included, comprising 366 patients (iHTN, n = 180; control, n = 186). Mean age was 65.8 ± 11.8 years, 60.9% were men, and the mean initial NIHSS was 5.4 ± 3.5. Target systolic blood pressure (SBP) was a 15-25% increase from baseline SBP using phenylephrine. Functional independence at 90-days occurred more often in the iHTN group than in controls (68.8% vs 50.5%; RR = 1.37; 95% CI, 1.09-1.73; P = 0.007). Hemorrhagic transformation was uncommon and did not differ significantly between groups (3.3% vs 0.5%; RR = 2.08; 95% CI, 0.05-88.07; P = 0.70). In our study, phenylephrine-induced hypertension was associated with greater 90-day functional independence in selected AIS subtypes,without a significant increase in hemorrhagic transformation. However, the limited studies, predominance of retrospective designs, exclusively Asian cohorts, and heterogeneity in treatment protocols and populations warrant cautious interpretation and underscore the need for larger multicenter RCTs.

The application of cryotherapy in the extraction of airway blood clots has gained increased precedence over Fogarty catheter and biopsy forceps. The cryoprobe, passed through a flexible bronchoscope, adheres and aids in the removal of foreign body through cryoadhesion within minutes. Besides blood clots, this method was found to be extremely efficient in removing different kinds of foreign bodies including food particles like peanuts, pills, and inspissated mucus.

Susac Syndrome was first described as an inflammatory microangiopathy of the brain and retina. Since then, multiple articles have been published in attempts to improve the understanding of this rare disease. Clinically Susac Syndrome is known to present with triad of encephalopathy, sensorineural hearing loss and branch of retinal artery occlusion (BRAO), along with characteristic “snowball” or “spoke” appearing white matter lesions of the corpus callosum. It has been characterized by vast heterogeneity in terms of its presenting symptoms, severity, and clinical course. Although subset of patients present with severe forms of Susac Syndrome and can develop prominent residual neurologic deficits, it has been reported to be mostly non-life-threatening and only few fatal cases have been described in the literature. Based on the available case reports with fatal outcome, mortality has been related to the systemic complications either during acute disease flare or during chronic-progressive phase. We describe a case of fulminant Susac Syndrome complicated by the sudden and rapid progression of diffuse cerebral edema leading to brain herniation and ultimate brain death, in order to increase awareness of this rare and catastrophic complication.
