Mesenteric Ischemia: A Case of Extrapulmonary Presentation in COVID-19

Coronavirus 2019 (COVID-19) is a predominantly respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It creates a hypercoagulable milieu, manifesting at varied extrapulmonary sites as pulmonary embolism, deep venous thrombosis, stroke, myocardial infarction, and mesenteric ischemia. The pathophysiology behind this hypercoagulability is still not entirely understood, although a heightened systemic inflammatory response to the virus is deemed responsible. We herein report a case of a 36-year-old healthy male who presented with an acute abdomen and was found to have extensive mesenteric and portal venous thrombosis with bowel gangrene. The patient underwent emergency exploration with ileal resection and end-ileostomy. The hypercoagulability panel was negative, but a postoperative chest radiograph revealed suspicious ground-glass opacities. Given the ongoing global COVID-19 pandemic, we considered testing for SARSCoV-2. A positive test for SARS-CoV-2 led us to attribute the thrombotic event to COVID-19. With anticoagulation and supportive therapy, the patient went on to make a steady recovery. A non-specific clinical manifestation of COVID-19 necessitates considering mesenteric venous thrombosis as a differential diagnosis in patients with acute abdomen.Copyright © 2023 Author.

Fournier's Gangrene as a Possible Surgical Complication of COVID-19: Two Case Reports and Literature Review

Fournier's gangrene (FG) is a rare form of necrotizing fasciitis affecting the perineal, perianal, or genital areas. The infection is usually seen in diabetic, alcoholic, or immunosuppressed patients. Urgent debridement and broad-spectrum antibiotics are the first-line therapy, where in some cases soft tissue reconstruction is required. We report two patients who developed FG during COVID-19 infection. None of the patients had a history of diabetes mellitus, alcoholism, or immune deficiency. The only reported health condition was COVID-19 infection. Emergent debridement and elective reconstruction were performed for both of the patients. High index of suspicion is required during the examination of the perineum and the genitalia of suspected patients with COVID-19 infection for early diagnosis and prevention of further complications. Larger studies are required to indicate the exact incidence of FG in patients with COVID 19 infection.

A rare case of complicated pancreatitis due to leptospirosis.

The COVID-19 pandemic and the actions taken to combat it have greatly impacted the health infrastructure of all nations. Here we present a rare case of leptospirosis with severe acute pancreatitis, bilateral peripheral gangrene, disseminated intravascular coagulopathy and multiorgan failure. This is a rare presentation of leptospirosis wherein the patient had no history suggestive of acquisition of leptospires. The patient was started on doxycycline but still could not be saved due to the multisystem involvement.

Recurrent intussusception with ileal perforation as a complication of Blue Rubber Bleb Nevus Syndrome in a pediatric patient

Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital condition, characterized by multiple venous malformations that may involve any organ system, most commonly the skin or the gastrointestinal tract. These lesions are often responsible for chronic blood loss and secondary anemia, and in rare situations may cause severe complications such as intussusception, volvulus, and intestinal infarction. Intussusception as a complication of BRBNS, although a known complication of the disease, has rarely been reported, especially in the Philippines. In the Philippine Society for Orphan Disorders, only 2 cases of BRBNS are currently included in the organization, including the patient presented in the case report. The treatment of BRBNS that involves the gastrointestinal tract depends on the extent of intestinal involvement and severity of the disease. The treatment aims to preserve the GI tract as much as possible due to the high recurrence in the disease. In this case report, we present a 13 year-old male with BRBNS with previous history of intussusception, successfully managed conservatively;however, upon recurrence, underwent exploratory laparotomy wherein a subcentimeter perforation in the antimesenteric border of the proximal ileum was noted, together with a gangrenous intussuscipiens, and multiple mulberry-like formations on the antimesenteric border of the small bowels. Histopathological findings of the resected bowels showed multiple cavernous hemangiomas consistent with BRBNS. The postoperative course of the patient was unremarkable.Copyright © 2023 The Authors

Cutaneous manifestations of COVID-19.

COVID - 19 can be accompanied by a variety of cutaneous abnormalities, which mainly include vascular lesions chilblain - like lesions, livedo reticularis, purpura, ecchymosis, acral cyanosis, gangrene, etcand inflammatory lesionsdiffuse erythema, morbilliform exanthem, acute urticaria, varicella- like exanthem, etc. Some types of skin lesions may be the first symptom or the only clinical manifestation of COVID-19.Copyright © 2022 Chinese Journal of Dermatology.

Acute appendicitis

Acute appendicitis is inflammation of the vermiform appendix. It is the commonest general surgical emergency in children and young adults, yet its diagnosis can still confound even the most skilled surgeon due to its highly variable presentation of appendicitis, with fewer than 50% of patients exhibiting classical features. Taking a detailed history and performing a careful examination remains the cornerstone of diagnosis. Urinalysis and blood tests, particularly C-reactive protein, are useful adjuncts and are performed routinely. Radiological imaging, commonly ultrasound and computed tomography scans, also have a role when the diagnosis is unclear and/or other common conditions need to be excluded, such as gynaecological pathology in young females. Nevertheless 20% of appendices removed in UK are histologically normal. Appendicitis scoring systems may further assist in stratifying risk and increasing the accuracy of diagnosis. Recently, there has been growing interest in non-surgical management of appendicitis, particularly during the COVID-19 pandemic. Antibiotics alone have been used to successfully treat uncomplicated appendicitis (without perforation, abscess or gangrene) in the short-term, however nearly 40% of these cases eventually require appendicectomy. Surgery, usually laparoscopic appendicectomy, remains the treatment of choice for acute appendicitis and non-operative management is reserved for specific cases.Copyright © 2023

A Persistent Nightmare: A Case of Recurrent Brachial Artery Thrombosis

Background Brachial artery thrombosis can be seen with thromboembolism, hypercoagulability, and arterial thoracic outlet syndrome. Case A 33-year-old healthy female construction worker presented with right hand discoloration and pain. She suffered a COVID-19 infection 8 weeks prior with hand symptoms developing shortly thereafter. She could no longer work due to the pain. Duplex ultrasound and CTA of the right upper extremity (Figure) demonstrated localized thrombosis of the right brachial artery. The workup yielded no aortic or intracardiac thrombus, and cardiac event monitor showed no atrial arrhythmia. She underwent thrombectomy with brachial artery stenting and was found, during surgery, to have distal ulnar artery occlusion. Two days post-op, she had recurrent pain and was found to have brachial artery recurrent thrombosis. She underwent urgent brachial-brachial bypass. Arm pain continued despite graft patency, so ulnarpalmar bypass was performed. Decision-making Hypercoagulability workup, including antiphospholipid antibody, protein C, protein S, homocysteine, and Lp(a), was negative. Neither central thrombus on TEE nor evidence of thoracic outlet syndrome was found. As a diagnosis of exclusion, brachial artery thrombosis was ascribed to COVID infection. Despite rivaroxaban, the patient developed gangrene (Panel C) requiring partial digit amputation. Conclusion We present a case of COVID-19-induced recurrent brachial artery thrombosis despite surgical intervention. [Formula presented]Copyright © 2023 American College of Cardiology Foundation

Pioneering wound treatment in a suffragette military hospital in World War 1

In the face of massive numbers of casualties returning to the UK in World War 1, health services were rapidly reorganized under the leadership of Sir Alfred Keogh. Hundreds of military hospitals were set up. Sir Alfred personally asked two women doctors, both militant suffragettes and members of the British Women's Social and Political Union, to set up and run a hospital in London. This remarkable hospital was to pioneer new antiseptic treatments for wounds. Endell Street Military Hospital was set up in 1915 by doctors Flora Murray and Louisa Garrett Anderson. The hospital was staffed and run solely by women, treating 26 000 patients in 520 beds over the course of the war. One of their most heroic contributions was to the care of wounds in injured soldiers returning from France. Throughout the war wound infections led to the deaths of thousands of soldiers and contributed to significant morbidity such as limb loss in countless others. In 1916 James Rutherford Morrison, Professor of Surgery in Durham, invented bismuth iodoform paste (BIPP) for the treatment of wound infections. The paste has significant antimicrobial properties. The Endell Street doctors contacted Morrison in June 1916 and started using his formulation on injured patients. By early 1917 they had treated > 400 patients with gunshot wounds, compound fractures, septic wounds, through-and-through wounds and foreign body wounds with BIPP, reporting their findings in The Lancet (Garrett Anderson L, Chambers H. The treatment of septic wounds with bismuth-iodoform-paraffin paste. Lancet 1917;189: 331-3). They reported no cases of tetanus or gas gangrene and were able to explain side-effects such as iodine and bismuth poisoning, why it occurred and how it could be avoided. BIPP has been in use constantly since 1916, and is still used today in ear, nose and throat departments, especially for packing nasal cavities. By changing from the traditional eusol (sodium hypochlorite solution) to BIPP Drs Murray and Anderson reduced dressing changes from daily to once every 7-14 days, saving staff time, costs and hugely improving outcomes. These women doctors saved hundreds of lives and pioneered wound treatments that are still used today. Both were awarded the CBE for their services, but sadly the hospital staff were sacked at the end of the war, when the hospital closed. This form of pioneering work, conducted under great strain with limited resources is still to be seen today in the COVID-19 pandemic.

A Rare and Complex Case of Non-suicidal Self-Mutilation in a Patient With Schizophrenia.

The literature describing acts of non-suicidal self-mutilation (NSSM) in the adult population is limited. Of the cases that document NSSM, a disproportionate number of these individuals have a history of psychiatric illnesses. Although the motivation to perform NSSM varies across patients, the literature suggests that past self-injurious behaviors, extreme religious delusions, and command hallucinations are the most significant risk factors. The primary forms of NSSM include ocular, genital, and limb mutilation. Limb mutilation is the least common of the three and typically occurs proximal to the wrist or hand. Here, we present a rare case involving a 42-year-old man with schizophrenia who was hospitalized due to osteomyelitis of his autoamputated digits. This case is unique in involving multiple digits of the hand and using a rare amputation method. We aim to compare this case with the existing body of work on NSSM and identify factors that may predispose patients to act on these extreme impulses. We also highlight a novel interventional program that reduces psychiatric and medical comorbidities.

[Ischemic gangrene of the upper limb associated with COVID-19 infection: about 2 cases]. / Gangrène ischémique du membre supérieur corrélée à l'infection de la COVID-19: à propos de 2 cas.

Clinical manifestations of COVID-19 have changed a lot, ranging from respiratory and Ear, Nose and Throat (ENT) symptoms to extra pulmonary thrombotic, neurological, cardiac and renal complications. We here report the case of two patients with SARS-CoV-2 pneumonia whose course was marked by prolonged upper limb ischemia. The association between venous, but also arterial, thrombotic complications and viral infection is now well established, and appears to be related to hypercoagulability.

Upper extremity necrotizing fasciitis in a Covid-19 patient.

The novel COVID-19 virus has resulted in an immense burden in healthcare throughout the world. In addition to respiratory complications, COVID-19 has been associated with hypercoagulability and ischemic changes. We report a case of a patient with COVID-19 who presented with a rapidly progressing necrotizing fasciitis treated in our institution.

Major Amputation Needed to Treat Purulent Tenosynovitis and Necrotizing Fasciitis in a Patient with a Human Bite and Severe COVID-19.

Background: Peripheral human bite wounds are rarely serious and are typically treated medically, with the most complex cases requiring only minor amputation or excision of the infected site. There are few to no reports documenting the development of purulent tenosynovitis, necrotizing fasciitis, and osteomyelitis from these lesions. Major amputations are required only rarely in these cases. Case Presentation: A 71-year-old woman presented with an uncontrolled infection following a self-inflicted bite wound to her left middle finger. A bacterial culture of the lesion revealed methicillin-resistant Staphylococcus aureus (MRSA). The infection could not be controlled with antibiotics or additional interventions, including debridement and minor amputation. She contracted severe COVID-19 while in the hospital which limited the available treatment options. In an attempt to control the infection, the patient ultimately underwent a major amputation of the distal left forearm. While recovering from the procedure, the patient succumbed to septic shock and cardiopulmonary arrest. Conclusion: The unusual progression of this case may be attributed to the interventions required to treat acute COVID-19 as well as a variety of confounding factors. For example, vasopressors and steroids used to treat severely-ill patients compromise the local and systemic physiologic responses to acute bacterial infection. It is important to reconsider clinical expectations during the pandemic and intervene as early as possible to prevent ongoing damage and clinical deterioration.

STRUCTURE OF MORTALITY AMONG PATIENTS WITH DIABETES MELLITUS IN THE REPUBLIC OF UZBEKISTAN DURING COVID-19 PANDEMIA

BACKGROUND. The COVID-19 pandemic has caused enormous damage to all countries of the world. Patients with diabetes mellitus are a separate risk group for the consequences of COVID-19, both in the acute and in the long-term period. AIM. To study change in the structure of mortality among patients with diabetes in the Republic of Uzbekistan during the COVID-19 pandemic. MATERIALS AND METHODS. We analyzed the data of the report forms of endocrinological dispensaries for reasons of deaths registered among patients with 2 diabetes mellitus in 2020 and compared these indicators with the data of 2019. RESULTS. In 2020, mortality among patients with diabetes increased 1.5 times compared to 2019 and was 4.3% (compared to 2.8% in 2019). Among the causes of deaths, cardiovascular accidents prevailed: 57,9% in 2020 (48,0% in 2019), cerebrovascular accidents (15,6% in 2020 and 24,2% in 2019), chronic kidney disease (12,0% and 15,1%), gangrene, sepsis (1,2% and 1,8%), the frequency of hyper- and hypoglycemic comas as causes of death was 0.6% both in 2019 and in 2020, however, the absolute number increased in 2020. Among the <<other>> causes of death (12.8% in 2020 and 10,2% in 2019), COVID-19 itself was 52,3%, pneumonia 17,2%, pulmonary embolism 1%, oncological diseases 12%, liver cirrhosis 12%. CONCLUSIONS. Despite the fact that COVID-19 caused deaths in 6.7% of patients with diabetes, the COVID-19 pandemic caused a significant increase in mortality - 1.5 times - among patients with diabetes, mainly due to acute cardiovascular accidents, stroke, as well as accelerating the progression of chronic complications of diabetes, in particular chronic kidney disease.

Topical steroid menace: A case series of severe debilitating infections during the COVID-19 pandemic

Background: Topical corticosteroids is a boon and also a bane in treating chronic skin conditions. The risk of cutaneous infections due to topical steroids increases with their potency, dose, and duration of treatment. Herein, we present a case series of severe debilitating infections secondary to topical steroid abuse. Materials and Methods: We came across five cases of severe skin infection following the prolonged application of topical steroids. These cases gave a history of the use of steroid creams for persistent skin conditions and the inability to visit the hospital due to the prevailing COVID-19 pandemic. Observations: We came across two cases of crusted scabies, two cases of Fournier's gangrene, and a case of erosio interdigitalis blastomycetica. These cases had been using topical steroids for a prolonged period for other dermatological conditions. Conclusion: We propose that, as crusted scabies and erosio interdigitalis blastomycetica mimic various other papulosquamous disorders, a KOH examination is a diagnostic tool. Topical steroid abuse is one of the predisposing factors for Fournier's gangrene. [ FROM AUTHOR]

The ChoCO-W prospective observational global study: Does COVID-19 increase gangrenous cholecystitis?

BACKGROUND: The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. METHODS: Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. RESULTS: A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. CONCLUSIONS: The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands.

Management of Fournier's Gangrene in a COVID-19 Patient: Challenges and Dilemmas.

Fournier's gangrene is a urologic emergency manifested as an aggressive form of necrotizing fasciitis. Co-infection of Fournier's gangrene with COVID-19 might have catastrophic sequelae. We report a case of a 69-year-old male patient, unvaccinated against coronavirus, was obese, and with type 2 diabetes diagnosed with Fournier's gangrene. Apart from administration of piperacillin/tazobactam and clindamycin, the patient underwent surgical debridement four hours after his presentation. Postoperatively, the PCR test for COVID-19 was proved to be positive. The patients develop septic shock necessitating the delivery of dopamine, supplemental oxygen, and thromboprophylaxis. On the seventh postoperative day, left testicular ischemia was developed and ipsilateral orchiectomy was performed. After his full recovery from an in-hospital infection by Acinetobacter baumannii, the patient was transferred to the plastic surgery department. The prompt surgical debridement has likely counterbalanced the health risk originated from COVID-19 infection, contributing to the patient's full recovery. Testicular ischemia is a very rare condition in necrotizing fasciitis of the genital and perineal space and it could be attributed primarily to the thrombotic nature of coronavirus. Due to the assault of multiple organs and systems, a medical board consisting of urologists and other medical specialties substantially contributed to the favorable outcome.

Management of Myasthenic Crisis Triggered by Surgery and Concomitant SARS-CoV-2 Infection via IVIG Infusion During Inpatient Rehabilitation

Case Diagnosis: Managing myasthenia gravis (MG) crisis and preventing prolonged hospital stay in a patient with recent surgery and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia via intravenous immune globulin (IVIG) infusion during inpatient rehabilitation. Case Description or Program Description: A 62-year-old male with past medical history of MG, human immunodeficiency virus, osteoporosis, Sjogren's disease, diabetes, peripheral artery disease, and prior left above the knee amputation was admitted to inpatient rehabilitation following SARS-CoV-2 pneumonia, right lower extremity bypass grafting and right great toe amputation secondary to worsening peripheral vascular disease and gangrene. Course was notable for worsening lethargy, vision complaints, and supplemental oxygen requirement. Physical exam was below baseline and notable for bilateral fatiguable ptosis with curtain sign, positive Cogan lid twitch, and eye closure muscle strength graded 4+/5. Patient responded well to IVIG infusion for suspected myasthenic crisis. Patient later developed scrotal lesions which were treated with intravenous acyclovir given high suspicion of herpes simplex virus in the setting of immunosuppression. Setting(s): Inpatient Rehabilitation Assessment/Results: Patient received 5 days of IVIG infusion for myasthenic crisis secondary to recent surgery and SARS-CoV-2 pneumonia. Despite multiple complications, the patient did not require transfer to acute care for medical management and met inpatient goals prior to discharge. Discussion (relevance): During the pandemic, rehabilitation facilities have noted more cases complicated by the effects of concomitant SARS-CoV-2 infection and the impact it has on the immunosuppressed population. Of note, double insults like surgery and infection can trigger flares in patients with autoimmune diseases. This case highlights the benefits of providing comprehensive resources during inpatient rehabilitation to avoid disruption of care, prolonged hospitalization, and additional costs. Conclusion(s): This case study demonstrates the higher level of medical diagnosis and management capable in the acute inpatient rehabilitation setting to facilitate a complex patient's rehabilitation course without interruption.

THAT BLOODY CLOT DOES NOT ALWAYS NEED A TUNNEL TO MIGRATE: A CASE OF MULTIPLE ARTERIAL AND VENOUS THROMBOSIS IN A COVID-19 PATIENT

SESSION TITLE: Rare Cases of Nervous System and Thrombotic Complication Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Covid 19 virus has impacted nearly 450 million people across the globe;ranging from an asymptomatic carrier state to respiratory symptoms, cardiovascular symptoms, hematologic manifestations and multiorgan failure to death. Thrombotic events are one of its devastating complications. CASE PRESENTATION: A 66 year old man with a history of diabetes mellitus, hypertension and 30 pack years smoking history presented to the emergency room with hypoxia and altered mental status. On exam, his GCS was 8/15 and oxygen saturation was 85% on room air. He was subsequently intubated. CTA chest demonstrated bilateral diffuse ground glass opacities and left pulmonary embolism (PE). CT abdomen and pelvis showed multifocal infarcts in the right kidney with findings suggestive of renal artery thrombosis. Initial platelet count was 80,000/ul with creatinine of 3.9 mg/dl and creatine kinase (CK) of 3977 u/l. His INR was 1.4. Patient was not a candidate for thrombolysis given his thrombocytopenia. He was started on intravenous (IV) heparin and given IV hydration. On day 3 of his admission, he developed dry gangrene of the toes. Ankle brachial index of the right lower extremity (LE) was 1.16 and left LE was 0. Duplex ultrasonography of left LE showed mid to distal popliteal artery thrombus occluding below knee popliteal and tibial arteries. Echocardiogram showed ejection fraction of 55% and bubble study was negative for any intra atrial or pulmonary shunting. On day 4 of his admission, he developed oliguria and his gangrene got worse. His platelet counts decreased to 36,000/ul. Other pertinent labs showed INR 1.2, PT 15.3, PTT 34, D dimer 14.82, fibrinogen 498, CK 6434 mg/dl, hemoglobin 13.2 g/dl, haptoglobin 243 mg/dl and LDH 1041 U/l. Given his poor prognosis in the setting of ventilator dependent respiratory failure, multiple thrombosis and kidney failure requiring hemodialysis, the family decided to withdraw care. DISCUSSION: There are multiple hypotheses of thrombus formation in Covid 19 infection such as interleukin 6 and other cytokines induced endothelial injury, angiogenesis and elevated prothrombotic factors such as factor VIII and fibrinogen. Our patient had PE, renal artery thrombosis and popliteal artery thrombosis. Despite being on full dose anticoagulation, he developed gangrene of the toes. His lab results were not consistent with disseminated intravascular coagulation, thrombotic thrombocytopenic purpura and he was not known to have any baseline hypercoagulable disorder. He did not have any intra cardiac shunts. Hence, it is most likely Covid 19 induced multiple arterial and venous thrombosis. CONCLUSIONS: The treatment of Covid 19 related thrombosis has become very challenging especially in the setting of multiple clots. It is crucial to have large multicenter studies to investigate vascular complications of Covid-19 and to formulate management strategies to ensure good patient outcomes.

A RARE CASE OF ASYMPTOMATIC COVID-19 INFECTION MASQUERADING AS PHLEGMASIA CERULEA DOLENS

SESSION TITLE: Look again: Infections and Mimics SESSION TYPE: Case Reports PRESENTED ON: 10/18/2022 11:15 am - 12:15 pm INTRODUCTION: Phlegmasia Cerulea Dolens (PCD) is a rare and critical condition caused by venous thrombosis requiring emergent treatment to prevent limb ischemia. COVID 19 has been widely reported to cause venous thromboembolism and compromise of tissue perfusion. We report a case of PCD in a patient with asymptomatic COVID-19 infection. CASE PRESENTATION: A 60 year-old female with no known medical history, unvaccinated for COVID-19 presented with sudden onset left lower extremity pain and swelling associated with numbness. Physical examination was remarkable for left lower extremity swelling with bluish discoloration, poikilothermia, and paraesthesia. Computed tomography angiogram (CTA) chest, abdomen and pelvis revealed left lower extremity deep vein thrombosis with compromised blood flow with focal thrombosis of the IVC extending inferiorly to the great saphenous and popliteal vein, along with small bilateral segmental and subsegmental pulmonary emboli. Diffuse Ground glass opacities suspicious for COVID-19 pneumonia. COVID-19 PCR was positive. Anticoagulation with heparin drip was initiated, and the patient underwent successful left iliocaval to popliteal vein thrombectomy and venoplasty by interventional radiology with successful restoration of circulation to the affected extremity. She was eventually transitioned to apixaban. She experienced marked improvement in her symptoms post procedure. DISCUSSION: Patients with COVID 19 develop venous thromboembolisms at an alarming rate despite thromboprophylaxis. The mechanism is likely explained by the virchow's triad (venous stasis, hypercoagulable state, vessel wall injury) in the setting of increased pro-inflammatory markers. We report the first case at our institution of PCD in the setting of COVID-19.We noted that our patient had a similar presentation as those reported in literature, which include acute leg swelling associated with pain and cyanosis. Complications include venous outflow obstruction, which can result in compartment syndrome with arterial ischemia, eventually progressing to gangrene of the affected limb. PCD is a very rare but life-threatening complication caused by extensive clot burden associated with acute limb ischemia and increased mortality rates. This condition requires emergent initiation of intravenous anticoagulation and thrombectomy with or without tissue plasminogen activator (tPA). If this condition is not treated in a timely fashion, it can result in acute limb ischemia and gangrene requiring amputation. CONCLUSIONS: Physicians should recognize PCD in patients who have been exposed to COVID-19 as it is a life-threatening condition which requires emergent initiation of anticoagulation and treatment. Diagnosis is usually made with clinical examination and ultrasonography or CT imaging. Management options include open thrombectomy with leg fasciotomy or catheter directed thrombolysis or percutaneous transluminal angioplasty.

ACUTE DIGITAL GANGRENE TRIGGERED BY COVID-19 COAGULOPATHY

SESSION TITLE: Post-COVID-19 Infection Complications SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: As the coronavirus pandemic continues to burden the global health care system, strong associations have emerged with hypercoagulability. Recent reports of Covid-19 support both venous and arterial thromboembolism, thus coagulopathy emerging as one of the most severe sequelae of the disease, which has also been associated with poorer outcomes. CASE PRESENTATION: A 71-year-old female with a past medical history of hypertension, type 2 diabetes, and obesity presented with progressively worsening shortness of breath and cough. She was found to be hypoxic to 80% on arrival and tested positive for COVID-19. She was subsequently intubated and admitted to the ICU. Her D-dimer was noted to be 9.04mcg/mLFEU (0-0.55mcg/mLFEU), ferritin 256ng/mL(10-291ng/mL), LDH 707 U/L(130-270U/L), CRP 138mg/L (< 10mg/L). She was treated with a ten-day course of dexamethasone and a five-day course of Remdesivir. On Day 7, purple discoloration was noted in the second to fifth digits of the left hand, concerning acute ischemia. Left upper extremity ultrasound revealed intraluminal heterogeneous echogenicity likely occlusive ulnar arterial thrombus with no flow to mid or distal segment and normal flow in the radial artery into a complete palmar arch. This was seen to be classical for micro-embolic phenomenon attributable to the hypercoagulable state associated with Covid-19 infection. Treatment with Heparin drip was initiated along with the local application of nitro paste. The patient was subsequently discharged home but re-presented a month later for gastrointestinal bleeding. At this admission, her left second digit was noted to express purulent drainage. Imaging confirmed osteomyelitis in the second through fifth digits and was referred to a tertiary center for definitive treatment. DISCUSSION: Covid-19 has been shown to provoke catastrophic inflammatory responses by triggering a dysfunctional cascade of thrombosis in the pulmonary vasculature leading to both micro and macroangiopathic manifestations. The quick progression of ischemia to digital gangrene, despite collateral circulation and early intervention, indicates severe microangiopathy. CONCLUSIONS: Thus physicians must always have a high index of suspicion for thromboembolic complications in patients with Covid-19. The development of severe complications despite prompt anticoagulation highlights the need for alternative or newer therapies like targeted immunotherapy that would effectively manage these complications of SARS-CoV-2.
