Phlegmasia caerulea dolens and venous gangrene

Transjugular ultrasound-assisted catheter direct fibrinolysis (EKOS) for relapsed IVC filter thrombosis and phlegmasia cerulea dolens

Phlegmasia cerulea dolens (PCD) is a devastating presentation of deep venous thrombosis (DVT), that may cause venous gangrene, amputation, and death. A 69-year old male presented with PCD in the lower limbs. Ultrasound (US) and CT-angiogram revealed lower extremities DVT cranially extended to iliac veins and inferior vena cava (IVC) involving an infrarenal IVC filter. In his history, there was 10 years earlier his first occurrence of filter-related PCD, which did require surgical thrombectomy. Currently, we gained access to IVC-filter thrombus from left internal jugular vein and easily placed an EKOS catheter in right femoral vein. Then we started the US-assisted fibrinolysis (EKOS) with low-dose r-TPA. Immediate overnight clinical improvement occurred and a postprocedure venography at 48 hours confirmed complete recanalization. We report the present case upon PCD to remark 2 unique features. First, we used successfully EKOS by transjugular route for PCD. EKOS combines the effectiveness of low dose r-TPA catheter direct thrombolysis (CDT) with the ultrasound's technology. The descending transjugular approach, previously unreported in this clinical setting, can reduce operative time, invasiveness and risk of filter's displacement in comparison with other thrombectomy devices used via popliteal or femoral approach. Second, we verified for the first time to the best of our knowledge the relapse of PCD in a very long time span (a decade) in the same patient underscoring the significance of vena cava filter as a powerful and persistent risk factor for IVC-thrombosis.

Case report of simultaneous phlegmasia cerulea dolens and acute limb ischemia

INTRODUCTION

Phlegmasia cerulea dolens (PCD) is a rare, life- and limb-threatening condition of acute massive deep vein thrombosis (DVT) that requires emergent therapeutic intervention. While endovascular therapy is the preferred treatment approach, we describe a case where surgical embolectomy is an alternative approach in specific scenarios. In our case, we presented a patient with simultaneous PCD and acute limb ischemia (ALI).

CASE REPORT

A patient presented with haematuria, abdominal pain, cyanotic changes in the limb, and sensory/motor deficits in the right lower limb. Imaging tests revealed thromboembolic occlusion of both the arterial and venous systems and a bleeding tumour in the pelvic region. Due to the rapid progression of symptoms, macroscopic haematuria with anaemia, renal failure, and the necessity for intervention in both the arterial and venous systems, we performed a successful simultaneous surgical embolectomy of the arterial and venous systems right lower limb, resulting in prompt symptom resolution.

DISCUSSION

Phlegmasia cerulea dolens is a rare manifestation of massive iliofemoral deep vein thrombosis. Its pathophysiology can indirectly compromise arterial patency. Treatment options include endovascular therapy - catheter-directed thrombolysis (CDT), percutaneous mechanical thrombectomy (PMT) or surgical intervention. These options carry risks, including damage to the venous endothelium or periprocedural pulmonary embolism. This case report demonstrates a situation where surgical intervention was a viable option. We presented a more endothelium-sparing surgical approach using a sterile compression bandage during embolectomy.

IN CONCLUSION

To date, there are no established guidelines from professional societies regarding the treatment of PCD. The authors emphasize the need for an individualized approach to patients with PCD. They also highlight the importance of access to comprehensive treatment, including both endovascular and surgical methods.

US of Lower Extremity Deep Vein Thrombosis: A Review

The standard protocol for lower extremity venous US extends from the common femoral vein through the deep calf veins with color and spectral Doppler sampling, allowing evaluation of acute deep vein thrombosis and differentiation from postthrombotic change.

Iliac Vein Stenting and Thrombectomy Result in Limb Salvage in Phlegmasia Caerulea Dolens as a Result of Heavy Fibroid Burden

Phlegmasia cerulea dolens is a devastating sequelae of propagating deep vein thrombosis causing total venous outflow obstruction of an extremity. It is characterized by significant pain, edema, cyanosis, and critical limb ischemia and may progress toward venous gangrene. Morbidity and mortality rates associated with this phenomenon are high. Treatment options are limited and consist of early and aggressive therapeutic anticoagulation and fluid resuscitation, followed by thrombectomy or thrombolysis if the patient fails to respond clinically in 6-12 hours.

Phlegmasia cerulea dolens after endovenous cyanoacrylate closure of incompetent small saphenous vein

A previously healthy 70-year-old woman underwent cyanoacrylate closure of an incompetent left small saphenous vein. Six days later, grade 2 treatment-induced thrombosis occurred at the sapheno-popliteal junction. Three days later, the patient presented with pale, cold pain in the left lower extremity. Diffuse thrombosis of the left lower extremity involved the small and great saphenous and deep veins. The patient was admitted and immediately administered heparin with anticoagulant factors, with symptoms began resolving 1 d later. The superficial vein thrombi were resolved. Although a deep venous thrombus remained, symptoms disappeared, and the patient was discharged.

Three-Year Outcomes, Risk Factors for Restenosis After Stenting for DVT Combined with Iliac Vein Compression Syndrome

This study aimed to evaluate the safety and efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) and stenting for treating acute iliofemoral deep venous thrombosis (DVT) combined with iliac vein compression syndrome (IVCS), and to identify the predictors of stent restenosis. Patients with acute proximal DVT combined with IVCS underwent PCDT and stenting from January 2017 to December 2022 were enrolled. Primary and secondary patency were assessed by duplex ultrasound (DUS). The morbidity of postthrombotic syndrome (PTS) was assessed by the Villalta score. Risk factors for stent restenosis were assessed using univariate and multivariate Cox regression models. Total of 254 patients were included. The mean follow-up time was 36.06 ± 17.66 months. The primary patency rates at 1 year, 3 years, and 5 years were 92.5%±1.7%, 85.4%±2.4%, and 82.4%±2.9%, respectively. The incidence of stent restenosis was 14.2%. Discontinuation of anticoagulants within one year [hazard ratio (HR) = 5.03; P = .048] was the factor associated with acute in-stent thrombosis. Previous DVT history (HR =2.29; P = .037) and stent placement across the inguinal ligament (HR =6.70; P < .001) were identified as independent risk factors significantly associated with stent restenosis. The overall PTS rate was 19.3%. PCDT with stenting is safe and effective for patients with iliofemoral DVT secondary to IVCS, leading to low rates of PTS. Previous DVT history and stents placed across the inguinal ligament may be predictors of stent restenosis. Furthermore, stent restenosis typically occurs within one year and is mainly caused by acute thrombosis due to discontinuation of anticoagulants.

Lower limb amputation following venous cannulation for VA-ECMO: a case report

Lower limb amputation following arterial cannulation for VA-ECMO has been described in the literature. Limb ischemia however following venous cannulation is very rare and not quite understood. We present a case of limb ischemia following venous cannulation. A combination of venous congestion, compartment syndrome and subsequent arterial insufficiency is the proposed pathophysiology. Shock and use of vasopressors are compounding factors. Limb ischemia can be transient and reversible if diagnosed immediately and treated by early removal of the cannula. Our patient was unstable and ECMO dependent, and removal of the cannula was not an option. This resulted in limb loss and eventual above knee amputation. Use of the smallest appropriate venous cannula and early fasciotomy, in addition to hemodynamic optimization are measures that could help in preventing major amputation.

Delayed onset phlegmasia cerulea dolens post-SARS-CoV-2 infection treated with minimally invasive clot retrieval technology

Coronavirus disease 2019 is associated with a significant venous thromboembolic risk. Phlegmasia cerulean dolens is a severe form of deep vein thrombosis that can lead to acute limb ischemia. In this report, we present a 58-year-old woman who developed a delayed-onset left lower extremity phlegmasia cerulean dolens 8 weeks after coronavirus disease 2019 onset that led to compartment syndrome and acute limb ischemia from external compression of the arterial vasculature from edematous muscle. The patient received an emergent minimally invasive percutaneous mechanical thrombectomy and four-compartment fasciotomy, resulting in adequate perfusion and ultimately made a full recovery.

Successful treatment of phlegmasia cerulea dolens with percutaneous thrombectomy and catheter-directed thrombolysis: A case report

INTRODUCTION

Phlegmasia cerulea dolens (PCD) is an uncommon condition of acute deep vein thrombosis, characterized by marked swelling of the affected limb with pain and cyanosis. High mortality and morbidity rates have been reported. Early diagnosis, quick and effective treatment are crucial for preventing potential limb loss or even death.

PATIENT CONCERNS

A 39-year-old woman presented to our emergency department with painful swelling and cyanotic discoloration of the left lower limb for 2 days.

DIAGNOSES

Computed tomography revealed thrombosis in the left common iliac vein and inferior vena cava. Angiography demonstrated extensive venous occlusion from the lower inferior vena cava to the left popliteal vein. The diagnosis of PCD was made.

INTERVENTIONS

Systemic anticoagulation with intravenous unfractionated heparin was initiated immediately. Mechanical thrombectomy with Angiojet and angioplasty were performed, and catheter-directed thrombolysis (CDT) was administered subsequently.

OUTCOMES

Follow-up angiography revealed regression of the thrombosis and the opacification of the deep vein was restored. The patient was discharged from the hospital uneventfully.

CONCLUSIONS

PCD is a rare but potentially limb and life-threatening condition that requires immediate recognition. Treatment should be in a timely manner. Anticoagulation alone may be inadequate and more aggressive management such as CDT and thrombectomy should be considered.

Spontaneous gas gangrene of the lower limb in a patient with rectal cancer: A fatal diagnostic pitfall

Spontaneous gas gangrene of lower limb is rare. It may complicate digestive cancer or neutropenia. We report a case of spontaneous gas gangrene of the lower limb complicating a rectal cancer, initially diagnosed as deep vein thrombosis. The diagnostic delay was fatal.

Phlegmasia cerulea dolens causing compartment syndrome

BACKGROUND

Phlegmasia cerulea dolens (PCD) is a rare condition characterized by a severely swollen, cyanotic, blue extremity due to a large proximal (iliofemoral) deep venous thrombosis extending into the collateral veins. Mortality in PCD ranges 20-40%. Due to severely compromised venous drainage, compartment pressures can rapidly increase 16-fold within 6 h, but rarely result in arterial compromise.

CASE REPORT

We present a case of a middle-aged woman with no prior history of deep venous thrombosis, with a blue swollen left leg in intractable severe pain unresponsive to 3 doses of hydromorphone. Her pain was successfully alleviated with IV Lidocaine. Patient was found to have phlegmasia cerulea dolens resulting in compartment syndrome of her left leg. Although the patient initially had no motor function, after catheter-directed thrombolysis and emergent thrombectomy, she regained her motor function and made a full recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Phlegmasia cerulea dolens complicated by severe compartment syndrome is a rare entity. Prompt recognition and treatment are necessary to prevent irreversible limb ischemia and associated morbidity and mortality. IV Lidocaine may be considered as an option for analgesia for such patients.

Reverse Takutsubo Cardiomyopathy in a Patient with Phlegmasia Cerulea Dolens

Reverse takotsubo cardiomyopathy (rTTC) is a rare variant of takotsubo cardiomyopathy (TTC) which is characterized by reversible left ventricular (LV) dysfunction. Emotional and physical stress have been implicated in triggering TTC especially in postmenopausal women. TTC and its variants are becoming more recognized due to the widespread adoption of early coronary angiography in the setting of acute coronary syndromes. A man in his late 50s presented to the emergency department with left lower extremity pain, swelling, and cyanosis. Clinical assessment was consistent with phlegmasia cerulea dolens, with deep venous thrombosis detected by venous duplex ultrasound. During his admission, he developed clinical and EKG findings suggestive of acute coronary syndrome. Emergent coronary angiography and ventriculography revealed basal and midventricular hypokinesis with hyperdynamic left ventricular apex, depressed LV dysfunction without coronary artery obstruction diagnostic of reverse takotsubo cardiomyopathy. Venous thromboembolism is a rare finding but has been associated with takotsubo cardiomyopathy and should be considered in the appropriate setting.

Phlegmasia Cerulea Dolens, a Deadly Complication of Deep Vein Thrombosis: Case Report and Review of Literature

Phlegmasia cerulea dolens (PCD) is a rare limb and life-threatening condition caused by extensive deep vein thrombosis of the extremities, and it is classically associated with extensive oedema, severe pain, and skin mottling, which may lead to compartment syndrome, venous gangrene, and even death. A 40-year-old male, with a background history of right femoral vein thrombosis, cardiomyopathy, with an ejection fraction of only 10%, presented with three days history of progressive swelling, pain, and discolouration of the right lower limb. He was treated with therapeutic low molecular weight heparin along with supportive care with intravenous fluids and pain relief. In view of his poor ejection fraction, he was treated non-operatively with supportive care. The patient succumbed after three months of presentation. PCD is a rare vascular emergency condition that if not recognized early and treated aggressively may lead to higher morbidity and mortality.

Direct Iliac Vein Stenting in Phlegmasia Cerulea Dolens Caused by May-Thurner Syndrome

Phlegmasia cerulea dolens (PCD) is an uncommon but potentially limb-threatening complication of acute deep vein thrombosis. A 56-year-old male presented with PCD. Color Doppler ultrasonography revealed extensive thrombosis of the left superficial and common femoral and external and common iliac veins. After an unsuccessful iliofemoral thrombectomy, contrast-enhanced computed tomography revealed iliofemoral deep vein thrombosis due to May-Thurner syndrome (MTS). After the deployment of an inferior vena cava filter, the thrombotic occlusion was traversed with a guidewire and direct stenting was performed to achieve immediate recanalization. The patient was discharged two days after the procedure, demonstrating significant clinical improvement. MTS is a rare cause of PCD. Direct iliac vein stenting may be a safe and effective alternative treatment for rapid recanalization if percutaneous mechanical thrombectomy devices are unavailable.

A Case of Phlegmasia Cerulea Dolens in a Patient With COVID-19, Effectively Ttreated With Fasciotomy and Mechanical Thrombectomy

Coronavirus disease 2019 (COVID-19) has been widely reported to be associated with increased risk of Venous Thromboembolism, both deep vein thrombosis (DVT) and pulmonary embolism. A rare and extreme manifestation of DVT is Phlegmasia cerulea dolens, characterized by poor tissue perfusion due to marked limb swelling which can progress to limb and life-threatening venous gangrene. We report the case of a 53-year-old man with severe SARS-CoV2 pneumonia who developed acute iliofemoral DVT leading to acute limb ischemia due to Phlegmasia cerulea dolens. The patient underwent successful emergent fasciotomy and mechanical thrombectomy with removal of extensive thrombus burden and restoration of normal venous circulation. Our case highlights the importance of clinical vigilance and early implementation of therapeutic interventions to avoid adverse outcomes in patients who develop SARS-CoV2 induced Venous Thromboembolism complications.

Hypercoagulability Due to COVID-19 Leading to Impending Phlegmasia Cerulea Dolens and Sub-Massive Bilateral Pulmonary Embolism

This is a case report of a 47-year-old male with a history of hypertension and pre-diabetes who presented to the emergency department with dyspnea, progressive unilateral leg swelling and pain. The patient tested positive for coronavirus disease 2019 (COVID-19) infection about a week earlier. The patient was found to have an extensive clot burden of his lower extremity veins, both deep and superficial, which extended to his inferior vena cava (IVC). Based on the patient's clinical exam and ultrasound findings, the patient was diagnosed with impending phlegmasia cerulea dolens. Due to his renal failure, the patient was taken for a ventilation/perfusion (V/Q) scan which found widespread V/Q mismatch highly suggestive of pulmonary embolism. Interventional radiology took the patient for lower extremity venogram, catheter-directed alteplase administration, and IVC filter placement. The patient was admitted to the intensive care unit (ICU) for further management and had a stable recovery.

Phlegmasia Alba Dolens Complicating Rhabdomyolysis

A 57-year-old woman with obesity, severe dyslipidemia and hypertension presented with acute onset of excruciating pain at left leg followed by entire leg swelling without a specific provocation. Physical examination revealed a significant left lower limb oedema along with pale skin, livedo reticularis, poikilothermia, and diminished distal artery pulsation. Urgent vascular Doppler sonography of left lower limb showed obstructive venous thrombus and non-compressible vessel at level of iliofemoral vein. Arterial systems were without any obliteration but with relatively reduced flow to distal part. Blood test resulted in significantly raised creatinine and creatine kinase (CK) level. Diagnosis of phlegmasia alba dolens with complication of rhabdomyolysis and acute kidney injury had been made initially. The patient was treated with heparin as well as rehydration using saline solution and bicarbonate. Eventually, she had clinical improvement during hospitalization and been discharged with resolution of creatinine and CK level.

Successful thrombectomy and thrombolysis of deep vein thrombosis in a patient with acute phlegmasia cerulea dolens with May-Thurner anatomy

Phlegmasia cerulea dolens (PCD) is a rare and important diagnosis to consider in the setting of a painful, swollen, and cyanotic lower extremity. We report a 59-year-old female diagnosed with PCD 3 days status post extended head and neck surgery with additional imaging findings concerning for May-Thurner anatomy. This case presentation is pathognomonic for PCD. Risk factors, pathogenesis, and management are described.

A new treatment paradigm for phlegmasia cerulea dolen: Single stage endovascular pharmacomechanical thrombectomy with venoplasty and stenting

BACKGROUND

Phlegmasia Cerulae Dolen (PCD) is potentially a lethal disease but there is currently no established treatment algorithm for it. The aim of this study was to assess the safety and effectiveness of single stage endovascular pharmacomechanical thrombectomy with venoplasty and stenting in the treatment of PCD.

METHOD

This was a retrospective single centre observational study of consecutive patients who underwent endovascular intervention for the treatment of PCD between June 2016 and March 2020. Clinical and procedural details were recorded. Procedural and clinical success rate, procedural complications, and 30 days mortality were reported.

RESULT

11 patients were treated during the study period. 2 (18.2%) had active malignancy. 63.6% were uncomplicated PCD on presentation. Common iliac vein compression or stenosis were demonstrated in all patients. Venous stents were implanted in all cases and procedures were successful in all cases. All patients had symptoms improvement at 72 hours post procedure. Other than 2 major bleeding complications, there was no other adverse event. The 30 days mortality was 18.2%. Active malignancy and the presence of anaemia were significantly associated with major complications.

CONCLUSION

Single stage endovascular thrombectomy and stenting was effective and safe in the treatment of patients with PCD. Common Iliac vein compression was a common underlying cause of PCD.

A Case of Phlegmasia Cerulea Dolens

Phlegmasia cerulea dolens (PCD) is a rare presenting condition that carries a high mortality and morbidity risk. It is a cannot miss diagnosis with potentially deadly sequelae, and we highlight the importance of a thorough physical examination and initiation of empiric treatment to help prevent such. 

Multimodal approach of venous recanalization in patients with a critical limb ischemia due to phlegmasia cerulea dolens: A case series of 17 patients in a single center

OBJECTIVES

Advanced phlegmasia cerulea dolens can be a hazardous complication of a deep vein thrombosis and rapid recanalization of the deep venous system is the most important factor.

METHOD

We describe the outcome of 17 patients with critical limb ischemia due to an advanced phlegmasia cerulea dolens. Venous thrombectomy was performed by a standardized operating procedure.

RESULTS

Venous recanalization was successful in all patients. An additional fasciotomy was not necessary. There were five patients with an underlying malignancy and eight patients with a simultaneous pulmonary embolism. We had one amputation of a forefoot and one death within 30 days representing a 30-day mortality and an amputation rate of 6%.

CONCLUSIONS

Early recanalization and recovery of the venous outflow is mandatory for success. A multimodal therapeutic approach of high urgency surgical thrombectomy in combination with endovenous strategies could be a successful treatment option for advanced phlegmasia cerulea dolens.

Phlegmasia Cerulea Dolens: A Life-Threatening Manifestation of Deep Vein Thrombosis

Deep vein thrombosis is a common condition encounter by hospitalists and managed by either oral or intravenous anti-coagulation. Although uncommon, phlegmasia cerulea dolens (PCD) is a life-threatening manifestation of acute deep vein thrombosis requiring early recognition and aggressive intervention to preserve life and limb. PCD is characterized by marked swelling of the lower extremities with pain and cyanosis, which often leads to gangrene and amputation. We present the case of a patient who developed PCD of her left lower extremity who was successfully treated with an EkoSonic™ endovascular catheter (Boston Scientific, Marlborough, MA, USA), which accelerates lytic dispersion of the thrombolytic drug through ultrasound technology.

Effective single-session percutaneous nonpharmacologic mechanical thrombectomy for phlegmasia cerulea dolens

Phlegmasia cerulea dolens can be a potentially devastating complication of severe deep venous thrombosis leading to limb ischemia and tissue necrosis. This report describes a patient presenting with phlegmasia cerulea dolens of the right lower extremity. Because of the urgent nature of the condition, percutaneous nonpharmacologic mechanical thrombectomy in a single session was pursued. Extensive thrombus burden was removed from the patient, and vessel patency was restored after balloon venoplasty. The patient's symptoms rapidly resolved, and the targeted vessels remain patent at 3-month follow-up.

Phlegmasia cerulea dolens in a patient treated with carboplatin

Phlegmasia cerulea dolens (PCD) is a rare, fulminant, potentially lethal and often debilitating presentation of deep venous thrombosis (DVT). Mortality and amputations rates are high. We present a rare case of bilateral PCD in the lower extremities. A 67-year-old woman presented with newly diagnosed squamous cell cancer of unknown primary origin with lymph node metastases to the neck. The patient started curatively intended treatment, consisting of removal of one lymph node on the neck, radiotherapy with concomitant carboplatin and nimorazol. The patient developed bilateral DVT in the legs. Despite treatment with low-molecular-weight heparins, the patient developed thrombosis in the inferior vena cava and lungs. Due to developing painful discolouration and necrosis on the legs, the patient underwent acute and extensive surgery. PCD is a severe and potentially lethal form of DVT. There are several known risk factors for developing DVT, including active cancer and the use of chemotherapy.

Isquemia arterial aguda de las extremidades: ¿cómo abordarla?

La isquemia arterial aguda de las extremidades se define como la interrupción abrupta del flujo sanguíneo a determinado tejido, lo cual afecta la integridad, la viabilidad de la extremidad, o ambas. Las causas son múltiples y pueden resumirse en dos procesos fisiopatológicos, trombóticos o embólicos, con lo que se puede establecer el pronóstico y el tratamiento según su causa. El cuadro sindrómico es variable, y típicamente, se identifica con las cinco “P” de Pratt (pain, pallor, pulselessness, paralysis and paresthesia); se cuenta con múltiples ayudas diagnósticas, pero la arteriografía sigue siendo el método estándar para el diagnóstico. Con el advenimiento de los avances tecnológicos y los procedimientos vasculares, el salvamento de las extremidades ha venido en aumento y ha disminuido la extensión de las amputaciones, lo cual conlleva una mayor tasa de rehabilitación y de reincorporación a la vida social.

Phlegmasia Cerulea Dolens in a Patient with Breast Cancer and Inferior Vena Cava Hypoplasia

Background

No clear guidelines exist for the management of phlegmasia cerulea dolens. This case report shows how a hybrid approach might be successful. It also shows how rare pathologies can combine to create a life- and limb-threatening condition. Case Presentation. A 75-year-old man, known for nephrotic syndrome currently under investigation, presented to the emergency department with a 24-hour history of left leg swelling followed by intense pain. The left lower limb showed a phlegmasia cerulean dolens. Renal function, coagulation profile, and inflammatory parameters were normal; D-Dimers 5,6 mg/L. The CT scan showed juxtarenal thrombosis of the hypoplastic IVC, involving both renal veins, reaching the left iliac-femoral-popliteal axis, with collateralization to the pelvic and mesenteric veins, associated with bilateral segmental pulmonary embolisms. A suspected left breast nodule was also found. Intravenous heparin was immediately administered, and urgent hybrid procedure with surgical thrombectomy and venous angiography and thromboaspiration, liberating the iliolumbar collaterals, was performed. A lateral leg fasciotomy was mandatory due to the phlegmasia cerulea. Postoperative Doppler US showed a good venous compressibility of the left leg. Thrombophilia screening was negative. The breast nodule was biopsied showing an invasive ductal carcinoma. The patient was discharged with oral rivaroxaban and indication for left mastectomy and oncological therapy with aromatase inhibitors.

Conclusion

This case highlights the dramatic consequence of different risk factors for venous thromboembolism as cancer and nephrotic syndrome in a patient with hypoplasia of the inferior cava vein. Venous thromboaspiration has been used in order to timely recanalize important collaterals. Phlegmasia cerulea dolens was resolved after the procedure and lateral calf fasciotomy. Further evidence is needed to clearly define the role of venous thromboaspiration in the treatment of complex proximal deep venous thrombosis of the lower extremity.

Phlegmasia cerulea dolens as an initial manifestation of a fistula between a ruptured iliac artery aneurysm and the iliac vein

Phlegmasia cerulea dolens (PCD) is caused by obstruction of limb venous return that may result in venous gangrene and limb loss. We present a case of a fistula between a ruptured right common iliac artery aneurysm and the left common iliac vein (ilioiliac arteriovenous fistula [AVF]), which initially manifested as left PCD and acute renal failure. Resection of the aneurysm and repair of the AVF immediately improved the PCD and acute renal failure. We should be aware that an iliac AVF might present as PCD and should keep this in mind.

Endovascular and Open Surgery for Deep Vein Thrombosis

The surgical treatment of deep venous thrombosis (DVT) has significantly evolved and is focused on different strategies of early thrombus removal in the acute phase and deep venous recanalization or bypass in the chronic phase. Along with the use of anticoagulation agents, endovascular techniques based on catheter-directed thrombolysis and pharmacomechanical thrombectomy have been increasingly used in patients with acute extensive DVT. Patient selection is crucial to provide optimal outcomes and minimize complications.

[Phlebological emergencies]

BACKGROUND

Deep and superficial vein thromboses as well as variceal hemorrhages are emergencies. The risk of short- and long-term morbidity and mortality in vein thromboses is increased. Variceal hemorrhage harbors the risk of massive blood loss. Prompt and adequate therapy of these diseases is therefore essential.

OBJECTIVES

Our aim was to give an overview of these phlebological emergencies.

MATERIALS AND METHODS

Based on the current guidelines and supplemented by a selective literature search in PubMed, we summarize the most important aspects for clinical practice.

RESULTS

In deep vein thrombosis, therapeutic anticoagulation and compression therapy are indicated for a duration of at least 3-6 months. A shorter duration is associated with a considerably increased recurrence rate. Basic measures in superficial vein thrombosis comprise mobilization, cooling, and compression. In case of tenderness on palpation, non-steroidal anti-inflammatory drugs are recommended. Indication for anticoagulation and its dose depends on length of the thrombus and distance of the proximal part of the thrombus towards the deep veins. Variceal hemorrhage is a complication of advanced varicosis and can usually be handled with simple measures such as elevation of the extremity and compression.

CONCLUSIONS

Prompt diagnosis and therapy is essential in superficial and deep vein thrombosis to prevent short-term complications such as pulmonary embolism and growth of the thrombus as well as long-term complications such as postthrombotic syndrome with secondary varicosis and chronic leg ulcer. After the occurrence of varicophlebitis or variceal hemorrhage, treatment of varicosis is indicated to prevent recurrences.

Upper Limb Phlegmasia Cerulea Dolens Secondary to Heparin-induced Thrombocytopenia: A Case Study

Introduction:

Phlegmasia cerulea dolens (PCD) is a rare pathology with a very high morbidity and mortality rate, which usually occurs in the lower limb. There is very little literature available to aid management.

Case Report:

We present a case of upper limb PCD in a 67-year-old female secondary to heparin-induced thrombocytopenia caused by warfarin bridging. She presented to the orthopedic team with upper limb compartment syndrome from a bleed around a peripherally inserted central catheter, for which she was urgently taken to the theater for fasciotomies. Postoperatively, the patient’s platelets dropped and the upper limb pain and swelling continued; after conservative management and anticoagulation failed the patient had an upper limb amputation of her right arm.

Conclusion:

With limited guidelines and management options restricted by the large fasciotomy wounds, we believe amputation was the patients’ best option.

Duplex Ultrasound Imaging of Iliac Venous Stents

Postthrombotic syndrome (PTS) is characterized by persistent leg edema, discoloration, pain, and ulceration in patients with a history of a deep vein thrombosis (DVT). We describe a 60-year-old man who had unilateral PTS develop from an iliofemoral DVT. The patient was treated with thrombolytic therapy using reteplase (Retavase, Centocor, Malvern, PA) followed by mechanical thrombectomy. Percutaneous transluminal angioplasty of the common and external iliac veins was subsequently performed, and a total of six self-expanding nitinol stents were deployed. Stent patency was assessed using an Advanced Technology Laboratories HDI 5000 (Philips Ultrasound, Bothell, WA) ultrasound machine with a curved 5-2 MHz transducer. B-mode images and color duplex ultrasonography with Doppler signals were recorded. Intraluminal echoes and the lack of vein compressibility confirmed the presence of remote thrombus more distally. However, widely patent stents with spontaneous, phasic blood flow were demonstrated in the common and external iliac veins. The patient's edema significantly improved. Deployment of stents to maintain vessel patency of diseased iliac veins is being performed with increasing frequency. Duplex ultrasonography is an inexpensive, noninvasive modality that can be used to follow patients who have had an endovascular venous intervention.

Management of Symmetrical Peripheral Gangrene

Symmetrical peripheral gangrene (SPG) is a rare, debilitating disease that deserves more widespread concern among the medical fraternities. The objective of this review is to outline the etiology, pathology findings, and management practices of SPG. About 18%–40% mortality rate was reported, and survivors have high frequency of multiple limb amputations. SPG is the hallmark of disseminated intravascular coagulation (DIC). The main pathogenesis theory, to date, is microthrombosis associated with disturbed procoagulant–anticoagulant balance. The treatment of SPG is largely anecdotal and theoretically involves heparin-based anticoagulation and substitution of natural anticoagulants. Early recognition, prompt management of DIC, and underlying conditions may halt the progression of the disease. The multicenter randomized controlled trial should be set up to formulate the proper treatment guidelines.

Management of Post-Traumatic Phlegmasia Cerulea Dolens via Right-to-Left Femoral Vein to Femoral Vein Bypass (Palma Procedure)

Phlegmasia cerulea dolens (PCD) is a rare condition resulting from venous occlusion that impairs arterial flow. We report a rare case of post-traumatic PCD after ligation of the iliac vein with successful treatment by right-to-left femoral vein to femoral vein bypass using left great saphenous vein (Palma procedure). The clinical presentation, diagnostic process, and approach to management along with a literature review on the operative management of PCD are presented in this case report.

Phlegmasia cerulean dolens: complication of femoral vein catheterization

There are three less frequent manifestations of acute massive venous thrombosis and obstruction of the venous drainage of an extremity. They are phlegmasia alba dolens, phlegmasia cerulean dolens (PCD), and venous gangrene. The term PCD differentiates ischemia-associated massive venous thrombosis from phlegmasia alba dolens, which describes fulminant venous thrombosis without ischemia. We present a 55-year-old hypertensive, who presented with paedal oedema and breathlessness at rest. About a month prior to this admission, she suffered dislocation of left patella. She was treated with a plaster cast and immobilization for 3 weeks. Her serum creatinine was 8.8 mg/dL. She was initiated on haemodialysis via two single-lumen catheters placed in left femoral vein. The femoral vein catheters were removed after third session of haemodialysis. On fourth day, the patient complained pain and blue discolouration of left toes. On examination, the left lower limb was swollen, discoloured, and cold with blebs up to upper one-third of left leg. The left dorsalis pedis and posterior tibial arteries were not palpable. A Doppler of veins of lower limb revealed, thrombosis of deep, and superficial venous system of left lower limb. As there was no response to anticoagulation below, knee amputation was performed.

Lower extremity compartment syndrome in the setting of iliofemoral deep vein thrombosis, phlegmasia cerulea dolens and factor VII deficiency

Acute compartment syndrome requires urgent fasciotomies to prevent irreversible muscle damage. We present a case of massive iliofemoral deep vein thrombosis (DVT) presenting as acute compartment syndrome. A healthy 21-year-old man presented with a 2-day history of worsening left leg pain with swelling and bluish discolouration. Clinical diagnosis of compartment syndrome secondary to phlegmasia cerulea dolens (PCD) was made and he underwent emergency fasciotomies. Postoperative venous duplex confirmed a massive iliofemoral DVT and intravenous heparin was started. Following skin grafting, the patient made a good recovery. Massive iliofemoral DVT is an uncommon cause of compartment syndrome and has been reported in lower limbs, secondary to PCD. Failure to treat early carries a high degree of morbidity, with amputation rates up to 50% and mortality rates between 25% and 40%. It is important to recognise compartment syndrome as an acute presentation of PCD. Urgent fasciotomies can prevent limb amputation and mortality.

Successful treatment of phlegmasia cerulea dolens in a nonagenarian patient with chronic iliac vein occlusion using a Cleaner thrombectomy device

A 91-year-old man was admitted to the emergency room with a 3-day history of severe pain, swelling and cyanosis in his left leg. Duplex ultrasound findings were suggestive of acute left popliteal and iliofemoral venous thrombosis. Heparin was initiated and pharmacomechanical thrombolysis (PMT) was performed with the use of a Cleaner thrombectomy device. At the completion of PMT, repeat venography revealed chronic proximal iliac vein occlusion. After the procedure, alteplase was infused via the intra-arterial catheter at a rate of 0.5 mg/h over 24 h to clear the thrombus distal to the popliteal vein and residual thrombus. The patient's signs and symptoms improved markedly after the intervention. There were no minor or systemic bleeding problems. He was discharged home 10 days after the procedure without any complications.

BACKGROUND

Herein we report a case of phlegmasia cerulea dolens, a form of venous thrombosis complicated by arterial ischaemia.

PATIENTS AND METHODS

A 69-year-old man presented a bilateral trophic condition of the lower limbs that had appeared 3 weeks earlier. The patient had a history of metastatic urothelial bladder carcinoma and arteritis. Clinical examination revealed right leg ulcers with massive bilateral oedema of the lower limbs, cyanosis and local ischaemia. Doppler ultrasound revealed bilateral and proximal deep vein thrombosis (sural and superficial femoral veins of the right leg; sural and iliac veins of the left leg) without any distal arterial flow. We concluded on a diagnosis of bilateral phlegmasia cerulea dolens.

DISCUSSION

Phlegmasia cerulea dolens is a particular type of deep venous thrombosis in which a proximal venous thrombus is combined with arterial ischaemic signs due to brutal and massive oedema and slowing down of arterial flow. In most cases, the lower limbs are involved, with malignancy being the most common cause. It should be suspected in the presence of the classical triad of "pain, oedema and cyanosis", with confirmation by Doppler ultrasound. There is no general consensus regarding standard management. Traditionally, systemic anticoagulation has been the mainstay of treatment for this condition. Endovascular surgery may be a possibility in some cases. Prompt diagnosis and rapid treatment initiation are paramount in order to improve the prognosis of this severe condition with ominous prospects.
