Evaluation of the International Society on Thrombosis and Haemostasis definition of major bleeding in Arizona rattlesnake bites.

INTRODUCTION: In 2023, a group of experts proposed that a definition of major bleeding in pharmaceutically anticoagulated patients be used in all snakebite trials. This includes bleeding that results in death, is life-threatening, causes chronic sequelae, or consumes major healthcare resources, including bleeding into a major area or hemoglobin concentration decrease ≥20 g/L. We hypothesized that a decline in hemoglobin concentration ≥20 g/L is common but rarely clinically significant in our population of Arizona rattlesnake bite patients. METHODS: Poison center records of rattlesnake bites in humans from 2018 through 2022 were retrospectively reviewed and assessed for major bleeding by the above criteria. RESULTS: Four hundred and eighty-one patients met the inclusion criteria, of whom 265 (55.1%) had a hemoglobin concentration decrease ≥20 g/L. No patients died, and there was no evidence of bleeding into a critical organ. Three patients (1.1%) received blood transfusions. A decrease in hemoglobin concentration ≥20 g/L was 100% sensitive for identifying the major bleeding-associated outcomes; however, specificity was only 45.2%. Measures of healthcare utilization and chronic sequelae were somewhat higher in patients with a decrease in hemoglobin concentration ≥20 g/L. DISCUSSION: Laboratory manifestations of hemotoxicity were common in this population, but hemorrhage was rare. While over half of patients met the major bleeding criterion of a decline in hemoglobin concentration ≥20 g/L, only 1.1% had bleeding that was potentially life-threatening as measured by receipt of a red blood cell transfusion. None died or had bleeding into a critical area. While nonspecific for major bleeding, a drop in hemoglobin concentration correlated with worse envenomation severity: these patients received more vials of antivenom, had a higher medical bill, a longer hospital stay, and were less likely to report full recovery at 90 days. CONCLUSIONS: A decrease in hemoglobin concentration ≥20 g/L should not be used as evidence of major bleeding for Arizona rattlesnake envenomation studies, but it may have a role as an indirect marker of envenomation severity.

Successful Surgical Management of a Ruptured Intracranial Aneurysm in a Nine-Month-Old Male: A Rare Pediatric Case.

Intracranial aneurysms in pediatric populations are rare, with a distinct clinical profile compared to adult cases. This case report describes the clinical presentation, diagnosis, and treatment of a nine-month-old male with an intracranial aneurysm. The child presented with convulsions, a depressed sensorium, and subsequent neurological deficits. Initial imaging revealed subarachnoid hemorrhage, and further angiographic studies identified an aneurysm rupture from the parietal branch of the right middle cerebral artery. The patient underwent successful neurosurgical intervention, including right craniotomy and aneurysm clipping. Post-operative recovery was marked by gradual neurological improvement and the absence of further seizures. This case underscores the importance of prompt diagnostic imaging and surgical management in pediatric intracranial aneurysms, contributing to favorable outcomes despite the rarity of the condition in this age group.

Capsule endoscopy for small bowel bleed: Current update.

Small intestine, hitherto an obscure area for endoscopists before 2000, is now easily evaluated non-invasively using capsule endoscopy and invasively by device-assisted enteroscopies. Major advances in understanding the causes and management of small bowel diseases have been in obscure gastrointestinal (GI) bleed, currently re-named as small bowel bleed, after the discovery of capsule endoscopy. The current article is a narrative review of the technology of capsule endoscopy, its advantages and limitations, future perspective and Indian studies on its utility in patients with small bowel bleed. Till date, eight large series reporting 2319 patients with obscure GI bleed (1554 overt and 765 occult) undergoing capsule endoscopy have been reported from India. Overall yield of capsule endoscopy to detect lesions in these studies varied from 43.5% to 90%. The major causes detected in various studies for small bowel bleed include vascular malformation, portal hypertensive enteropathy, ulcer, stricture, tumor, polyps, etc. Hookworm can cause both occult as well as overt small bowel bleed as shown mainly from India. Capsule endoscopy has also been quite safe in patients with small bowel bleed as despite 0.6% to 15% retention of imaging capsule in Indian studies, development of clinically evident small bowel obstruction has rarely been reported. The major limitations of capsule endoscopy include lack of maneuvrability and therapeutic capability. Research is in progress to overcome some of the limitations of the current capsule endoscopy system. It is concluded that discovery of capsule endoscopy has brought a new paradigm in GI endoscopy and explored a hitherto unexplored area of GI tract, i.e. small bowel that continued to be a black box for the endoscopists.

A Rare Case of Malignant Insulinoma Associated With Gastrointestinal Bleed.

A gastrointestinal bleed (GIB) in the setting of metastatic insulinoma is a rare phenomenon. It appears that cases of metastatic insulinoma causing GIB are rare, often influenced by the tumor's location. Our case involves an 82-year-old male with dementia and a history of recurrent hypoglycemia, presenting with an episode of altered mental status. The patient exhibited hypoglycemia alongside a melena episode and anemia. Diagnostic criteria, including Whipple's triad, confirmed endogenous insulin production. Computed tomography (CT) showed a left paraaortic/retroperitoneal mass. Esophagogastroduodenoscopy (EGD) visualized an extrinsic mass at the gastric body, which caused an ulcerated surface that was treated with clipping and hemostasis. The patient's recurrent hypoglycemic episodes were treated with glucose, while his GIB was managed with hemostasis and clipping. However, the patient was not a surgical candidate, and further medical treatment was ceased by the family.

Comparison of Postoperative Bleed Rates and Location of Bleed Between Vessel Sealing Devices after Laparoscopic Sleeve Gastrectomy.

Background: Laparoscopic sleeve gastrectomy (SG) is a commonly performed bariatric procedure. At our institution, two vessel sealing devices, Thunderbeat® (Olympus) and Maryland LigaSure™ (Covidien) are utilized for intraoperative dissection. Methods: A retrospective review of all patients who underwent primary SG from July 2013 through August 2022 was performed to evaluate postoperative bleeding (POB) rates between the two devices. The primary outcome measured was POB as defined by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), with secondary outcomes including reoperation, source of bleed, and overall safety. Results: A total of 8157 underwent SG. Average BMI and age were 43.2 kg/m2 and 37.1 years, respectively. A total of 6600 (80.9%) were female. Thunderbeat® was utilized in 5143 (63%) cases and Maryland LigaSure™ was used in 3014 (37%) cases. There was no significant difference in overall bleeding between the Thunderbeat® (18/5143, .35%) and the Maryland LigaSure™ (19/3014, .63%; P = .0689). However, there was a difference noted when comparing reoperation for bleeding between Thunderbeat® (9/5143, .17%) and Maryland LigaSure™ (13/3014, .43%; P = .0291). Furthermore, the location of bleeding in the reoperations was more common from the cut edge of the mesentery compared to the staple line with the Maryland LigaSure™ versus the Thunderbeat® (P = .038). Conclusions: The Thunderbeat® device is comparatively more hemostatic than the Maryland LigaSure™ for SG. The location of postoperative bleed may be related to vessel sealing devices used.

Upper gastrointestinal bleed secondary to large right hepatic artery pseudoaneurysm: a case report.

Hepatic artery pseudoaneurysm (HAP) is a serious rare life-threatening complication of Gastrointestinal surgeries that is often overlooked in diagnostic evaluation due to its rarity. We present a case of 71 years female, with a surgical history of gastric sleeve surgery, Roux-en-Y gastric bypass, and cholecystectomy, presenting with features of upper GI bleeding. Multiple diagnostic modalities were used and finally Magnetic Resonance Mesenteric Angiogram was able to pinpoint the location of the GI bleed as a hepatic artery pseudoaneurysm. Primary surgical repair used to be the mainstay treatment option for managing visceral aneurysms. However, due to advances in technology, embolization as well as implantation of covered stent grafts have become the preferred treatment for such lesions.

Hepatocellular adenomas with severe intra-abdominal bleeding, related to an underlying coagulation disorder: a case report.

BACKGROUND: Hepatocellular adenoma is a rare benign liver tumor. Typically, hepatocellular adenomas are solitary and are found in young women who use estrogen-containing contraceptives. The occurrence of multiple hepatocellular adenoma has been linked to higher body mass index, and as the prevalence of overweight increases, multiple hepatocellular adenomas are seen more often. An hepatocellular adenoma does not always necessitate treatment, as they can regress under conservative strategies. In incidental cases, an adenoma presents owing to bleeding, which is mostly self-limiting. If it is not, embolization of hepatic involved vessels is indicated. CASE PRESENTATION: In this case report, we discuss a 42-year old Caucasian woman with multiple hepatocellular bleeds, treated by multiple endovascular procedures. After the first embolization of an adenoma in the right liver lobe, a second bleed occurred in the left lobe, necessitating additional endovascular intervention. During admittance, treatment was complicated by pulmonary embolism and a pneumonia. During follow-up, our patient was diagnosed with antiphospholipid syndrome. CONCLUSION: Hepatocellular adenoma is a rare diagnosis that requires centralized expertise. This particular case illustrates the complexity of treatment strategies for associated intra-abdominal bleeding and possible complications. Although liver adenoma is often an incidental finding, it can also result in significant morbidity. Centralization of treatment leads to expertise in managing complex treatment strategies.

Evaluation of clinical outcome and predictors of mortality in patients undergoing antegrade transvenous variceal embolisation in adjunct to salvage TIPS for active uncontrolled gastric variceal bleeding.

OBJECTIVES: Salvage TIPS is indicated in patients with active endoscopically uncontrollable variceal bleeding. TIPS alone is not effective in management of gastric varices and BRTO requires favourable variceal anatomy. Concomittant placement of a TIPS stent with antegrade variceal embolisation leads to control of gastric variceal bleeding with no significant increase in portal pressure. MATERIALS AND METHODS: A single centre retrospective observational study where patients with active uncontrollable gastric variceal bleeding were included in the study. Technical success of the procedure, 5-day rebleed, 6-weeks and 6-months survival as well as other additional outcomes were evaluated. RESULTS: A total of 18 patients were included in the study. Technical success was 100% and significant non-target embolisation was seen in 0% patients. 6 week and 6 month survival rates were 66.67% with an overall survival of 108.786 days (censored at 180 days). 5 day rebleed rate was 11.1%. A significant difference in CTP score (p = 0.03), MELD Na score (p = 0.022), requirement of intubation (p = 0.038), hemoglobin levels (p = 0.042), hematocrit value (p = 0.018), PRBC infusion required prior to and after the procedure (p = 0.045, 0.044) and presence of refractory shock (p = 0.013) was observed between the survival and the mortality group. Post variceal bleeding hemoglobin levels, MAP and MELD-Na scores were significant predictors of mortality. CONCLUSION: TIPS in adjunct to antegrade transvenous embolisation is a safe and effective modality for management of active uncontrolled gastric variceal bleeding in patients with variceal anatomy unfavourable for performing RTO.

Finding the Balance: Venous Thromboembolism Prophylaxis during Hematochezia in Crohn's Disease.

Introduction: Despite heightened risk of venous thromboembolism (VTE) in hospitalized patients with inflammatory bowel disease (IBD), pharmacologic prophylaxis remains underutilized, particularly in those presenting with hematochezia. Although placement of retrievable inferior vena cava filters (rIVCF) may be considered in those with contraindications to anticoagulation and VTE risk, current recommendations from clinical guidelines are incongruent, leading to wide variation in practice. Case Presentation: This report highlights a case of rIVCF used in the management of recurrent VTEs in a patient hospitalized for persistent gastrointestinal bleeding. Conclusion: Our case demonstrates the need for a lower threshold for initiating VTE prophylaxis in patients with active IBD, even when hematochezia is the presenting symptom. A small group of patients with recurrent VTE and clear contraindications to anticoagulation may require IVCFs, necessitating close follow-up and monitoring for filter complications.

Metastatic Pure Choriocarcinoma Masquerading in the Gastrointestinal Tract.

This study presents a rare case of pure choriocarcinoma (PCC) with metastasis to the gastrointestinal tract in a 52-year-old male with a history of mixed germ cell tumor in remission. Despite negative oncology surveillance imaging, serum marker monitoring, and a recent colonoscopy, the patient presented with new-onset melena and dysphagia, leading to further diagnostic evaluation. Endoscopic examination revealed an ulcerated duodenal mass, and a computer tomography (CT)-guided liver biopsy confirmed metastatic PCC. This case highlights the aggressive nature of PCC and the importance of considering gastrointestinal metastasis in patients with atypical symptoms, even when in apparent remission.

Gastrointestinal Bleeding and Hemorrhagic Shock in a Patient Diagnosed With Disseminated Histoplasmosis.

A 63-year-old patient with HIV/AIDS and hepatitis B virus was found to have disseminated histoplasmosis with gastrointestinal bleeding. The patient was initially treated for sepsis, but the infectious workup was negative. Computed tomography of the abdomen and pelvis showed diffuse mesenteric and retroperitoneal lymphadenopathy, with plan for biopsy. Unfortunately, the patient had a Code Blue after having profuse hematochezia. Esophagogastroduodenoscopy disclosed actively bleeding duodenal ulcer; computed tomography angiography showed gastric and jejunal extravasation. The patient expired, and autopsy revealed histoplasmosis of duodenum and jejunum. Esophagogastroduodenoscopy is particularly helpful for timely diagnosis in immunocompromised patients with gastrointestinal bleed from suspected infections or malignancy.

Recurrent Upper Gastrointestinal Bleeding due to Radiation-Induced Hemorrhagic Gastroduodenal Ectasia: A Review of Current Treatment Options for Radiation-Induced Gastric Injury.

Introduction: Acute upper gastrointestinal bleeding is one of the most common medical emergencies that present to the hospital, and delineating the underlying etiology is essential to provide adequate definitive treatment. The purpose of this case report was to review the diagnosis and treatment of a rare complication known as radiation-induced hemorrhagic gastritis (RIHG) that can occur in patients with prior radiation exposure. The motivation for this study arose from the identification of a case within our institution. Case Presentation: The study involved a review of the diagnosis and management of a patient who presented with anemia and recurrent episodes of gastrointestinal bleeding at our institution after undergoing treatment for metastatic biliary adenocarcinoma. With the advent of new therapies, we aimed to investigate the various techniques utilized to manage these patients and highlight the importance of maintaining a high index of suspicion for RIHG as a potential etiology of gastrointestinal bleeding in patients with a relevant medical history of radiation exposure. Despite the literature review, we found that there is a lack of guidelines in the approach to the management of these patients. Conclusion: This case report underscores the rarity of radiation-induced gastritis and the complications that may arise from its diagnosis, including recurrent GI bleeding. Further investigation into identifying definitive treatment and creating guidelines for its management is desperately needed.

Racial Differences in Non-variceal Upper Gastrointestinal (GI) Bleeding: A Nationwide Study.

Background and aims Knowledge about the impact of race on non-variceal upper GI bleeding (NVUGIB) is limited. This study explored the racial differences in the etiology and outcome of NVUGIB. Methods We conducted a study from 2009 to 2014 using the Nationwide Inpatient Sample (NIS) database. NIS is the largest publicly available all-payer inpatient database in the USA with more than seven million hospital stays each year. The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for NVUGIB, esophagogastroduodenoscopy (EGD) and demographics were obtained. The outcomes of interest were in-hospital mortality, hospital length of stay (HLOS), total hospital charges, admission to the intensive care unit (ICU), and patient disposition. Analysis was conducted using Chi-square tests and Tukey multiple comparisons between groups. Results Among 1,082,516 patients with NVUGIB, African American and Native Americans had the highest proportions of hemorrhagic gastritis/duodenitis (8.2% and 4.2%, respectively) and Mallory-Weiss bleeding (10.4% and 5.4%, respectively; p<0.01). African Americans were less likely to get an EGD done within 24 hours of admission compared to Whites and Latinxs (45.9% vs 50.1% and 50.4%, respectively; p<0.001). In-hospital mortality was similar among African Americans, Latinxs, and Whites (5.8% vs 5.6% vs 5.9%, respectively; p=0.175). Asian/Pacific Islanders and African Americans were more likely to be admitted to the ICU (9.6% and 9.0%, respectively; p<0.001). Moreover, African Americans had a longer HLOS compared to Latinxs and Whites (7.5 vs 6.5 and 6.4 days, respectively; p<0.001). Conversely, Asian/Pacific Islanders and Latinx incurred the highest hospital total charges compared to African Americans and Whites ($81,821 and $69,267 vs $61,484 and $53,767, respectively; p<0.001). Conclusion African Americans are less likely to receive EGD within 24 hours of admission and are more likely to be admitted to the ICU with prolonged hospital lengths of stay. Latinxs are more likely to be uninsured and incur the highest hospital costs.

Jejunal Gastrointestinal Stromal Tumor Presenting as Hemorrhagic Shock.

Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal (GI) tract. Intermittent GI bleeding is the most common manifestation. Massive GI bleeding leading to syncopal episodes and hemorrhagic shock is a rare presentation of these tumors. Herein, we describe a case of a jejunal GIST presenting as massive bleeding.

A Closer Look into Gastrointestinal Bleeding in Heart Failure Patients.

BACKGROUND: The frequency and risk factors for gastrointestinal bleed (GIB) in patients with heart failure with reduced ejection fraction (HFrEF) have not been extensively researched. OBJECTIVE: We aim to assess the frequency of GIB in this subset of patients and identify potential risk factors for bleeding. This study will evaluate the frequency of commonly used antiplatelet and anticoagulation agents in the HFrEF population, as well as look at some of the endoscopic features of the GIB. METHODS: A retrospective cohort analysis of 670 patients admitted between November 2021 to August 2023 to a single urban, tertiary teaching institution with acute HFrEF ICD-10 codes. Upper or lower GIB (hematemesis, coffee ground emesis, melena or hematochezia during admission) was identified on a manual chart review. Patients with GIB were defined as our cases. No GIB was defined as our controls. Sub analysis included comparing the use of anticoagulant and antiplatelet between the cohort. Independent t test assessed statistical differences in the case and control groups RESULTS: Out of the 670 patients, 134 (20%) were identified with GIB. The cases were older than the controls (median age 77 vs. 70 years) (p = 0.001), had a lower hemoglobin (9 g/dL vs. 12 g/dL) (p =<0.05), and had higher BNP levels (7,938 pg/ml vs. 6472 pg/ml) (IQR: 3,239, 23,701) (p =<0.01). Among the anticoagulant users, 64% of cases were on an anticoagulant compared to 42% of the controls (p<0.05). Among the antiplatelet users, 68% of the controls were on one or more antiplatelet agents, compared to 52% in the controls (p = 0.01). When combining AC and AP treatment, there was no statistical difference between cases and controls. Ninety-three (69%) patients from cases had cross-sectional imaging with only 23 (25%) showing abnormal findings which included diverticulosis, colitis, and GI masses. When comparing upper endoscopy findings, the presence of esophageal diseases (esophagitis and esophageal varices) and gastric/duodenal diseases (gastritis, gastric ulcer, duodenal ulcer and AVM) were significantly higher in cases compared to controls (p < 0.05). In addition to the colonoscopy findings, polyps and diverticulosis were more prevalent in the cases compared to the controls (p = 0.01). CONCLUSION: Heart failure patients are at risk of developing GIB. Age and high BNP on admission are risk factors for GIB, the higher the BNP levels the higher risk of GIB. Anticoagulant and antiplatelet use are associated with a higher risk of bleeding. However, the addition of dual antiplatelet therapy or concurrent antiplatelet and anticoagulation does not increase the risk of GIB. Some of the most common upper endoscopy findings include esophagitis/gastritis and esophageal/gastric ulcer. In terms of colonoscopy, findings include colonic mass, diverticulosis and hemorrhoids.

Two Cases of Primary Aortoenteric Fistulas Diagnosed by Computed Tomography.

A primary aortoenteric fistula is a rare clinical entity that leads to severe upper gastrointestinal bleeding and carries a high risk of mortality, yet diagnosing aortoenteric fistulas remains challenging. Diagnosis is frequently delayed due to the uncommon and non-specific nature of the abdominal signs and symptoms. Rapid diagnosis and prompt surgical intervention are paramount to the successful management of this condition which is known for its profoundly poor prognosis. This report describes two cases of primary aortoenteric fistulas, one of which presented with melena and hematemesis, and the other presented with hematemesis and abdominal pain. In both cases, computed tomography angiography (CTA) demonstrated findings suggestive of an aortoenteric fistula, namely, locules of gas within the aortic lumen, which led to emergent surgical intervention. One patient underwent esophagogastroduodenoscopy while in the operating room before surgical intervention. One patient underwent repair with axillo-bifemoral bypass and the other with juxtarenal abdominal aortic aneurysm repair with a rifampin-soaked gelsoft dacron graft followed by primary bowel repair. Postoperative complications for one of the patients included duodenal repair breakdown as well as colonic ischemia. One patient made a meaningful recovery and remained without complications until the first postoperative visit two months after the repair. The other patient was discharged and then subsequently lost to follow-up. The two patients' successful outcomes of such a lethal condition were in large part due to rapid diagnosis with CTA and prompt surgical intervention.

Duodenal Varices Presenting as Lower Gastrointestinal Bleeding.

Duodenal varices pose a significant clinical challenge due to their association with severe gastrointestinal bleeding. This condition requires attention because of its acute severity, high morbidity, and mortality rates. The presented case underscores the importance of advancing both knowledge and treatment approaches for duodenal varices. This pursuit is aimed not only at improving immediate clinical outcomes but also at deepening our understanding of complications related to portal hypertension.

Unveiling the Rarity: A Case of a Mixed Neuroendocrine-Non-Neuroendocrine Tumor of the Gastroesophageal Junction.

Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are a rare group of heterogeneous tumors, consisting of an endocrine and a nonendocrine component, which can develop throughout the gastrointestinal (GI) tract. This case presents a 70-year-old man with a complex medical history who initially presented with an upper GI bleed. After being stabilized, he underwent an esophagogastroduodenoscopy (EGD) that revealed a suspicious gastroesophageal junction (GEJ) mass. Histopathological studies paired with immunohistochemical investigations of the mass confirmed the rare diagnosis of MiNENs. He then underwent an endoscopic submucosal dissection (ESD) with subsequent chemotherapy and adjunct radiotherapy, with no recurrence noted on post-treatment surveillance. This case highlights the need for an EGD, histopathological examination, and immunohistochemical staining for detecting the underlying etiology of an upper GI bleed.

Factors affecting radiation dose, radiation exposure time and procedural time in arterial embolization for active hemorrhage.

PURPOSE: To evaluate patient and procedure-related factors contributing to the radiation dose, cumulative fluoroscopy time (CFT), and procedural time (PT) of Arterial Embolization (AE) for suspected active bleeding. METHODS: Data on patients who underwent AE for suspected bleeding was retrospectively gathered between January 2019 and April 2022. Data collected included the dependent variables consisting of dose-area product (DAP), CFT, PT, and independent variables consisting of demographic, bleeding-specific, and procedure-specific parameters. All statistical computations were performed in SPSS statistics. The alpha value was set at 0.05. RESULTS: Data from a total of 148 AE were collected with an average patient's age of 61.06 ± 21.57 years. Higher DAP was independently associated with male sex (p < 0.002), age ranges between 46 and 65 years (p = 0.019) and > 66 years (p = 0.027), BMI above 30 (p = 0.016), attending with less than 10 years of experience (p = 0.01), and bleeding in the abdomen and pelvis (p = 0.027). Longer CFT was independently associated with attending with less than 10 years of experience (p < 0.001), having 2 (p = 0.004) or > 3 (p = 0.005) foci of bleed, and age between 46 and 65 years (p = 0.007) and ≥ 66 years (p = 0.017). Longer PT was independently associated with attending with less than 10 years of experience (p < 0.001) and having 2 (p = 0.014) or > 3 (p = 0.005) foci of bleed. CONCLUSION: The interventionist experience influenced radiation dose, CFT and PT. Dose was also affected by patients' sex, age, BMI, as well as bleeding location. CFT was also affected by patients' age, and both CFT and PT were also affected by the number of bleeding foci. These findings highlight the multifaceted factors that affect radiation dose and procedural time, emphasizing the importance of interventionist expertise, patient's age, sex, BMI, location and number of bleeds.

Middle Rectal Artery Pseudoaneurysm: A Case of Massive Lower Gastrointestinal Bleeding Managed With Coil Embolization.

Pseudoaneurysms of the middle rectal artery are rare. When encountered, these have the potential for significant morbidity and mortality due to bleeding and potential rupture. Endovascular embolization is a feasible option in the management of these pseudoaneurysms. The present report describes a case of a 43-year-old male presenting with hemorrhagic shock secondary to lower gastrointestinal bleeding one day after undergoing excision of an external perineal condyloma, incision and drainage of a perirectal abscess, and biopsy of a perianal mass. Angiographic imaging revealed a right middle rectal artery pseudoaneurysm. Selective embolization of the right middle rectal artery and bilateral superior rectal arteries was successfully performed. At the two-week post-embolization follow-up, hemoglobin was stable, and the patient reported normal bowel movements with no episodes of bleeding per rectum.
