Partielle einseitige Schwellkörperthrombose bei Homozysteinämie

Partial segmental thrombosis of the corpus cavernosum following Russell's viper bite

Snakebite envenoming (SBE) is common in rural communities living in tropical regions that often have fragile and/or overwhelmed healthcare systems. The complex scenarios around SBE lead to a high number of deaths, disabilities, and long-term consequences in patients. Russell's viper (Daboia russelii) is one of the most medically important snake species in India, which causes devastating pathological conditions characterised by a wide range of clinical manifestations. This broad spectrum of symptoms requires additional therapeutic interventions beyond the classical antivenom administration. Hence, positive outcomes for patients affected by SBE can be achieved with a better understanding of previous experiences describing clinical manifestations and various therapeutic interventions including for rare and underreported conditions. Here, we report an SBE victim who developed partial segmental thrombosis in the corpus cavernosum following Russell's viper envenomation and its diagnostic and treatment approaches. The patients received 180 ml of antivenom to resolve the abnormalities in their haematological parameters. Despite antivenom treatment, they developed severe pain in their genital region, and subsequent ultrasound and magnetic resonance imaging confirmed segmental thrombosis in the corpus cavernosum, which required supportive measures. The treatment using low molecular weight heparin, rivaroxaban and non-steroidal anti-inflammatory drugs resolved segmental thrombosis. In conclusion, this case report exemplifies the development of a rare segmental thrombosis in corpus cavernosum and how the medical, scientific, and general community can benefit from documenting clinical manifestations, medically relevant insights into patient care and the management of underreported complications.

Homocysteinemia: A rare cause of priapism

Priaprism is a persistent painful erection that continuous beyond or is unrelated to sexual stimulation. Majority of cases are idiopathic (46%), alcohol and drug related (21%), perineal trauma (12%), sickle cell anemia and hypercoagualable state related (11%). We report case of priapism caused by hyperhomocysteinemia with favorable outcome with only few cases so far reported in the literature to the best of our knowledge. A 31 year-old male referred to our institution with non resolving priaprism for the last 6 days. Immediate distal shunt (Al-ghorab) was created but it could not achieve the detumescence. The penile Doppler showed no flow into the corpora, so a proximal shunt (Quackels) was made which achieved satisfactory detumescence. On thorough evaluation for the cause of priaprism, only homocysteine level was found to be significantly raised (40.46 µmol/L), being the unusual and rare cause for priaprism. The patient was discharged on homocheck. In the follow-up the patient is on vacuum assisted device for the erectile dysfunction and has been advised for the penile implant. Priaprism being a urological emergency should be thoroughly evaluated even for the rare causes and should be timely intervened to avoid the unavoidable consequences of permanent erectile dysfunction.

Idiopathic Partial Thrombosis (IPT) of the Corpus Cavernosum: A Hypothesis-Generating Case Series and Review of the Literature

INTRODUCTION

Idiopathic partial thrombosis (IPT) of the corpus cavernosum is a rare condition. The etiology is not fully understood; however, the presence of an either or not congenital web in these patients may contribute to the development of IPT.

AIM

The aim of this study was to describe 18 new IPT cases and compare these with 38 cases found in the literature.

METHODS

A multicenter retrospective analysis was performed. Descriptive statistics are given.

MAIN OUTCOME MEASURES

The main outcome measures used were clinical presentation, clinical and radiographical diagnostics, treatment and resolution of symptoms.

RESULTS

Patients most frequently presented with perineal swelling (10/18; 56%) and pain (13/18; 72%), unilateral (12/18; 67%) or bilateral (4/18; 22%), and pain during erection (10/18; 72%). Penile curvature, dysuria or fever (each 1/18; 6%) were uncommon presenting symptoms. In our series, magnetic resonance imaging demonstrated a fibrous web in the corpus cavernosum in 100% of cases and was more bilaterally (11/18; 61%) than unilaterally (7/18; 39%) diagnosed. Cycling was found to be a provocative factor for IPT occurrence in patients at risk as 61% (11/18) of patients reported being a frequent cyclist with the episode of IPT occurring immediately after or during cycling activity in 8 out of 18 patients (8/18; 44%). In five centers, 15 patients were treated conservatively, the majority being treated with therapeutic doses of low molecular weight heparin and simultaneous anti-aggregant therapy. In one center, all three patients were treated with a surgical approach. Complete resolution of symptoms was noted in only 50% of cases.

CONCLUSION

IPT is a condition that presents typically with perineal pain and swelling. Cycling is often seen as a provocative factor, while the presence of a fibrous web at the level of the crurocavernosal junction is the underlying disorder allowing for entrapment of blood in the crura. Conservative treatment provides a reasonably good outcome in most cases. For therapy resistant cases, surgery can be considered.

Partial segmental thrombosis of the corpus cavernosum (PSTCC) diagnosed by contrast-enhanced ultrasound: a case report

Background

Partial segmental thrombosis of the corpus cavernosum (PSTCC) is a rare disease predominantly occurring in young men. Cardinal symptoms are pain and perineal swelling. Although several risk factors are described in the literature, the exact etiology of penile thrombosis remains unclear in most cases. MRI or ultrasound (US) is usually used for diagnosing this condition.

Case presentation

We report a case of penile thrombosis after left-sided varicocele ligature in a young patient. The diagnosis was established using contrast-enhanced ultrasound (CEUS) and was confirmed by contrast-enhanced magnetic resonance imaging (ceMRI). Successful conservative treatment consisted of systemic anticoagulation using low molecular weight heparin and acetylsalicylic acid.

Conclusion

PSTCC is a rare condition in young men and appears with massive pain and perineal swelling. In case of suspected PSTCC utilization of CEUS may be of diagnostic benefit.

Partial priapism

With only 34 prior cases in world literature, partial priapism (PP), also called partial segmental thrombosis of the corpus cavernosum, is a rare urological condition. The aetiology and treatment of PP is still unclear, but bicycle riding, trauma, drug usage, sexual intercourse, haematological diseases and α-blockers have been associated with PP. In this case report and world literature review, we describe the case of a 50-year-old man suffering from PP after ingesting 100 mg of sildenafil. The patient was treated with a surgical incision for corpus cavernosum and clot evacuation, as a conservative treatment of PP was not feasible due to severe pain and unresponsiveness to analgesics.

Idiopathic partial thrombosis of the corpus cavernosum: aetiology, diagnosis and treatment

Idiopathic partial thrombosis of the corpus cavernosum (IPT) is a rare cause of perineal pain involving thrombosis within the proximal corpora cavernosa. This article clarifies the aetiology and makes recommendations on diagnosis and treatment. Three cases are described and a systematic review of the literature is presented. Magnetic resonance imaging (MRI) scans of the penis conducted for reasons other than IPT were also reviewed, to compare the normal anatomy of the corpora cavernosa with that of IPT patients.Twenty-nine IPT cases were identified, including the three described here. All patients presented with perineal pain and in all cases the thrombus was located in the proximal part of the corpora cavernosa.IPT has been associated with haematological diseases, drugs, prior priapism, sexual activity, bicycle riding and aeroplane flights. A fibrous septum within the corporeal tissue has been identified with advanced imaging modalities. Ultrasound, computed tomography and MRI have proven useful in the diagnosis. Both surgical and medical treatments have been attempted and the results have usually been good. However, two cases of surgical treatment have resulted in erectile dysfunction. It is suggested that ITP is based on the development of penile thrombosis and/or priapism in the presence of a pre-existing fibrous septum in the corpora cavernosa. MRI should be used to confirm the presence of a thrombus and a septum. First choice of treatment is pain medication and systemic anticoagulation; more invasive treatments should only be attempted only if this approach fails.

Partial segmental thrombosis of the corpus cavernosum: a case report and a review of the literature

Partial segmental thrombosis of the corpus cavernosum (PSTCC) is a rare urological condition characterized by a painful, firm mass in the proximal part of the corpus cavernosum. The underlying pathophysiology of this condition is not fully understood. We present a case diagnosed by magnetic resonance imaging with complete clinical recovery after conservative treatment and novel associated findings, such as excessive alcohol intake. We also review the previous cases of PSTCC and propose a two hit model explaining PSTCC's etiology.
