We hereby present a case of iatrogenic dissection of the superior mesenteric artery dissection in a 63-year-old female undergoing a lumbar puncture (LP). She presented with severe diffused abdominal pain accompanied by lower back pain, nausea and vomiting a few hours after undergoing an LP due to ongoing headaches. Abdominal CT showed evidence of hemoperitoneum. She was then transferred to another facility and while in route received one unit of packed red blood cellsdue to drop in hemoglobin levels from 15 to 11 gm/dl. Physicians should consider the possibility of arterial variations and the level at which spinal tap is performed during interventions. Acute abdominal pain is a significant, common complaint that should be appropriately investigated.
Introduction:
With new legislation becoming more lenient regulating recreational cannabis use in the United States, the prevalence of cannabis has doubled since 2002 and continues to rise. While there have been some reports of the benefits of cannabis, medical literature has identified several adverse cardiovascular events. Cannabis as a significant risk factor for the acute coronary syndrome (ACS) has been suspected to be attributed to vascular inflammation and platelet activation as well as elevation in heart rate and blood pressure through sympathetic stimulation.
Methods:
We conducted a case-control study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) 2019 database to investigate hospitalizations for patients aged 18 years old or older with the primary diagnosis of ACS. Comorbidities were identified through their international classification of diseases, 10th revision (ICD-10 codes) recorded in the discharge record for each hospitalization. Records having cocaine or other stimulants were excluded. An alpha (p) value less than 0.05 was considered statistically significant.
Results:
Of the 34,948,093 records included in the study, 225,275 had a primary diagnosis of ACS, and 767,525 had evidence of cannabis use. The rate of cannabis use in the ACS group (2%, n= 4,490) was lower than the non-ACS group (2.2%, n=763,035, p<0.001), while the rate of smoking was higher in the ACS group [49.5% (n=111,405) vs 31.2% (n=10,840,496), p<0.001] . However, after adjusting for other cardiovascular risk factors in a multivariable logistic regression model, the odds of cannabis use were comparable to smoking (Table 1).
Conclusions:
In this retrospective case-control study, the odds of cannabis use were similar to the odds of smoking in the records with a primary admission diagnosis of ACS, highlighting cannabis as a strong potential cardiovascular risk factor. Prospective cohort studies are warranted to establish the causality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
