Objective: To clarify the histopathological characteristics of deep vein thrombosis (DVT) resulting in lethal pulmonary thromboembolism (PE).Subjects and Methods: We investigated 100 autopsy cases of PE from limb DVT. The distribution and chronology of DVT in each deep venous segment were examined. Venous segments were classified into three groups: iliofemoral vein, popliteal vein and calf vein (CV). The CV was subdivided into two subgroups, drainage veins of the soleal vein (SV) and non drainage veins of SV.Results: Eighty-nine patients had bilateral limb DVTs. CV was involved in all limbs with DVT with isolated calf DVTs were seen in 47% of patients. Fresh and organized thrombi were detected in 84% of patients. SV showed the highest incidence of DVTs in eight venous segments. The incidence of DVT gradually decreased according to the drainage route of the central SV. Proximal tips of fresh thrombi were mainly located in the popliteal vein and tibioperoneal trunk, occurring in these locations in 63% of limbs.Conclusions: SV is considered to be the primary site of DVT; the DVT then propagated to proximal veins through the drainage veins. Lethal thromboemboli would occur at proximal veins as a result of proximal propagation from calf DVTs.

Acute pulmonary thromboembolism is a catastrophic event, especially for hospitalized patients. The prognosis of pulmonary thromboembolism depends on the degree of pulmonary arterial occlusion. The mortality of massive pulmonary embolism is reportedly as high as 25% without cardiopulmonary arrest and 65% with cardiopulmonary arrest. In patients with unstable hemodynamics due to pulmonary thromboembolism, surgical pulmonary embolectomy is indicated for patients with a contraindication to thrombolysis, failed catheter therapy, or failed thrombolysis. Thrombolytic therapy adds an additional burden on patients who are at risk of potential hemorrhagic complications. It is also indicated if patients are already on a veno-arterial extra-corporate membrane oxygenator for circulatory collapse or cardiopulmonary arrest. The outcome for patients who require cardiopulmonary resuscitation for longer than 30 minutes is poor. Therefore, early triage for massive and sub-massive pulmonary embolism is crucial. A team approach including a cardiovascular surgeon may be effective to save critically ill patients. Prompt removal of emboli reduces the right ventricular load with quick recovery of cardiopulmonary function in the early postoperative period. A recent series reported excellent results, with in-hospital mortality of less than 10%. Surgical pulmonary embolectomy is an effective, safe, and easy procedure to save critical patients due to pulmonary thromboembolism.

<p>Bronchial artery–pulmonary artery arterio–venous malformation, previously known as "bronchial artery primary racemose hemangioma" is a rare vascular malformation. The literature surrounding the imaging findings and treatment is currently limited. We hereby describe the imaging findings and a novel endovascular approach of utilizing bi-directional embolization from both the pulmonary and bronchial artery to occlude the malformation, leading to thrombosis and resolution of symptoms. This strategy represents a potential treatment option of non-surgical patients in this rare malformation.</p>

Subclavian Artery Dissection (SAD) is a rare condition, generally due to arterial catheterization, blunt trauma or connective tissue disease. Spontaneous or minimally traumatic cases have also been reported. Clinical manifestations are usually chest and/or back pain, pulse loss and paresthesia, whereas nausea, dizziness and vomiting are present in case of involvement of the vertebral artery. We report an unusual case of a young woman presenting isolated left SAD after traffic accident, minimally symptomatic, and treated with medical therapy alone. A conservative management and a closed follow-up appear to be a safe approach in patients affected by uncomplicated SAD without other comorbidities.
